Sharp has seen fit to make a 60-inch LCD display and curved convex: a solution a bit different from the one we are used to, since so far the screens offered by the various companies were all concave, and in fact we have seen LG G Flex and LG G Flex 2 mount this type of display, of course, in addition to other products belonging to the area smartphones (and the scope TV, especially).

We said that the use of this display 60-inch mainly concerns the field of advertising, but not exclude a use in the field of information, since the screen can be installed especially on the columns, which are almost completely embraced by it (and this allows, of course, an at least partial vision from all perspectives, differently from what might happen with a screen not curved).

We have not yet release date and price available, as this Sharp 60-inch LCD display was simply an initial model: we will keep you updated if we were to find out more.

There’re more than 300 procedures to produce TFT LCD. The most advanced LCD, in which the array and cell process are highly automatic. Technically, every step in the process can lead to defects, and most of the defects have been eliminated through the development of TFT LCD technology.

Point defect is a kind of defect that some point on your screen don’t display correctly. There are mainly three situations: the point keeps displaying black or whitewhen the screen is working or the point can only display a single color.

In LCD, newton’s rings may occur on screen when two glass substrate haven’t been sealed well, so that one of the glass may form a convex lens and lead to light interference.

You may notice there are some screens have uneven display, which means some white area appears in dark picture or vice versa. We call this ‘mura’, a word originated from Japanese.

Mura is very common but it doesn’t affect the screen function severely, however it still bring bad look. Hence, many high end display manufacturers have their own standards of mura, and the displays without mura are of the best quality.

The present invention relates to a method for manufacturing a support frame of a display panel being used as a display device for personal computers, TV (television) sets, or a like; and more particularly to the method of manufacturing the support frame of the rectangular display panel which is used to support a portion surrounding the rectangular display panel and to the support frame of the rectangular display panel manufactured by the above method and to the display device equipped with the above support frame.

As a rectangular display panel, an LCD (Liquid Crystal Display) panel, a PDP (Plasma Display Panel), or panels made up of light emitting elements such as an EL (Electroluminescence), an LED (Light Emitting Diode), a VFD (Vacuum Fluorescent Display), or a like are conventionally available. In the LCD panel, a region surrounded by a scanning electrode mounted in a row direction and by a data electrode mounted in a column direction is used as a pixel, and by feeding a data signal produced from an image signal to a data electrode and by feeding a scanning signal produced from a synchronous signal to the scanning electrode, a character or an image is displayed on a display screen. Also, in the LCD panel, a data electrode driving circuit adapted to generate the above data signal and a scanning electrode driving circuit adapted to generate the above scanning signal, together with control circuits used to control these circuits, gray-scale power source, or a like, are formed integrally as an LCD module. As shown in FIG. 29, in an LCD module 1, a front of a portion surrounding the LCD module 1 is supported by an approximately □-shaped front frame 2 and a rear of the portion surrounding the LCD module 1 is supported by an approximately □-shaped center frame 3.

In the LCD module 1 shown in FIG. 29, the control circuits, gray-scale power source, or a like are mounted on a printed board 4, while the data electrode driving circuit made up of semiconductor circuits (ICs) is mounted on a film carrier tape electrically connecting the printed board 4 and an LCD panel 5 by each of a plurality of corresponding data electrodes and is packaged as TCPs (Tape Carrier Packages) 6 1to 6 8. The printed board 4 is attached to an upper frame 3 aof the center frame 3. Moreover, positioning members 7 (another positioning member 7 in a lower right portion is not shown) shown in FIG. 29 is used to correctly attach the LCD module 1 in a specified position of the center frame 3. In the positioning member 7 made of a resin, as shown in FIG. 30, two rectangular parallel-piped bodies 9 are formed integrally on an upper face of an approximately L-shaped substrate 8 in such a manner that axial lines of the two rectangular parallel-piped bodies 9 intersect each other at right angles and, in the vicinity of the two rectangular parallel-piped bodies 9, one circular hole 10 is formed. The positioning member 7 is fixed at the center frame 3 in a method as described below. That is, first, each of the two rectangular parallel-piped bodies 9 of the positioning member 7 is inserted, from a rear side of the center frame 3, into a larger size inserting hole 11 than each of upper areas of the two rectangular parallel-piped bodies 9 each being formed in four corners of the center frame 3. Then, a thread (not shown) is fitted, with some tolerance being allowed, into the circular hole 10 from a rear side of the L-shaped substrate 8 and is inserted fitly into a thread hole 12 formed in the vicinity of the inserting hole 11 of the center frame 3 to fix the positioning member 7 to the center frame 3.

Moreover, in a Japanese Patent Application Laid-open No. 2000-314872, another technology is disclosed. That is, in the example, as shown in FIG. 31, a □-shaped center frame 13 is assembled so as to have an approximately □-shaped configuration which is made up of two approximately L-shaped component members 13 aand 13 band end portions of each of the L-shaped component members 13 aand 13 bare placed at corners of the □-shaped center frame 13 being diagonally opposite to each other. Moreover, as shown in FIGS. 32A and 32B, a fitting/coupling section 14 made up of plane pierce-shaped convex portions 14 aand plane pierce-shaped concave portions 14 bis provided at a place where the L-shaped component member 13 ais to be coupled to the L-shaped component member 13 band another fitting/coupling section 15 with plane pierce-shaped convex portions 15 aand plane pierce-shaped concave portions 15 bis provided at a place where the L-shaped component member 13 ais also to be coupled to the L-shaped component member 13 b. In the L-shaped component members 13 aand 13 b, portions being extruded from a side line of each of the L-shaped component members 13 aand 13 bor being partitioned by dotted lines in side portions of each of the L-shaped component members 13 aand 13 bare bending margins 13 cto be used when the L-shaped component members 13 aand 13 bare bent so as to be approximately L-shaped in cross sections.

A constricted portion 14 cis formed in each of the plane pierce-shaped convex portions 14 aand a constricted portion 15 cis formed in each of the plane pierce-shaped convex portions 15 aand the constricted portion 14 cis formed in each of the plane pierce-shaped concave portions 14 band the constricted portion 15 cin each of the plane pierce-shaped concave portions 15 bTherefore, this causes the plane pierce-shaped convex portions 14 aand the plane pierce-shaped concave portions 15 ato be tightly fitted each other, thus preventing them from being separated from each other in a horizontal direction. In the plane pierce-shaped convex portions 14 aand 15 aare formed boss portions 14 dand 15 drespectively in a half-punched state by a press working method.

Next, a method for manufacturing the center frame 13 is explained. First, the fitting/coupling sections 14 and 15 in each of the L-shaped component members 13 aand 13 bare positioned to be fitted from upward and downward directions to cause the plane pierced-shaped convex portions 14 aand 15 ato be mechanically fitted into the plane pierced-shaped concave portions 14 band 15 b. Next, when the fitting/coupling sections 14 and 15 are crimped from upward and downward directions by using a pressing machine, each of the boss portions 14 dand 15 dis plastic-deformed and expanded, which causes the plane pierce-shaped convex portions 14 aand 15 aand the plane pierce-shaped concave portions 14 band 15 bto be fitted more tightly and to be integrated. Then, by bending the bending margins 13 cof each side using the pressing machine, the □-shaped center frame 13 having approximately the same shape as the □-shaped center frame 3 shown in FIG. 29 is manufactured. Hereinafter, this technology is called a “second conventional example”.

However, the first conventional example has a disadvantage in that, since the melting and bonding processes are included in the method of manufacturing the support frame for the display panel provided in the first conventional example, generally, long working hours are required. Another problem is that, when a laser deposition method is used for the melting and bonding processes, in particular, additional special equipment has to be prepared.

On the other hand, the method for manufacturing the support frame for the display panel provided in the second conventional example also has a disadvantage in that, since the formation of the constricted portions 14 cand 15 cis necessary, if hardness of the employed component member is very high, it is difficult to form such the constricted portions 14 cand 15 cprecisely. Thus, the constricted portions 14 cand 15 ccause low strength of the support frame itself. As a result, if the constricted portions 14 cand 15 chave not been precisely formed, when the plane pierce-shaped convex portions 14 aand 15 aand the plane pierce-shaped concave portions 14 band 15 bare mechanically fitted, there is a danger that the fitting/coupling sections 14 and 15 would not be fitted completely. Moreover, depending on conditions applied when the plane pierce-shaped convex portions 14 aand 15 aand the plane pierce-shaped concave portions 14 band 15 bare mechanically fitted, a case may occur in which both the plane pierce-shaped convex portions 14 aand 15 aand plane pierce-shaped concave portions 14 band 15 bor either of the plane pierce-shaped convex portions 14 aand 15 aor plane pierce-shaped concave portions 14 band 15 bare broken in the constricted portions 14 cand 15 c. This means that, in the second conventional example, types of component members or manufacturing conditions that can be applied are limited and, if types of the component members are erroneously selected or the manufacturing conditions are erroneously set, defectives continuously occur and a yield is decreased, as a result. Furthermore, in the case of the second conventional example, after the plane pierce-shaped convex portions 14 aand 15 aand the plane pierce-shaped concave portions 14 band 15 bare mechanically fitted, process of crimping the fitting/coupling sections 14 and 15 from upward and downward directions using the pressing machine is needed, which causes low productivity in manufacturing the support frame.

Furthermore, in an upper portion of the above LCD module 1, as shown in FIG. 29, a plurality of ICs making up the data electrode driving circuit is mounted on a film carrier tape which is packaged in a form of the TCPs 6 1to 6 8. Since the plurality of ICs generates data signals to be fed to the data electrode in the LCD panel 5, high frequency noises of about several kHzto 1 GHzoccur and, therefore, unless an electromagnetic shielding unit is provided, the noises cause an EMI (Electro Magnetic Interference) to other electronic devices. To solve this problem, it can be thought that, as a material for the front frame 2, iron or aluminum having high conductivity is used to have it serve also as an electromagnetic shielding unit. However, iron has a high specific gravity and high hardness and, therefore, when it is used for a large screen, a weight of a display device becomes high and iron is difficult to be processed. Aluminum has also a disadvantage because it is expensive. As a material for the front frame 2, conventionally, stainless steel is used which has low conductivity but small specific gravity and low hardness and, in a portion above the data electrode driving circuit, a copper foil having high conductivity is pasted up. Therefore, a process of pasting up the copper foil is additionally required which causes an increase in component counts and in the number of processes.

Moreover, in the conventional support frame, in order to attach the LCD module 1 exactly to a specified position in the center frame 3, the positioning member 7 is used. Therefore, a process of mounting the positioning member 7 is additionally required which also causes an increase in component counts and in the number of processes. Such the inconvenience as in the LCD also occurs more or less in the display panel such as PDP or panels made up of light emitting elements such as the EL, LED, VFD or a like in an approximately same manner.

In view of the above, it is a first object of the present invention to provide a method for manufacturing a support frame of a display panel which is capable of fabricating the support frame of the display panel having high strength within short working time, without use of additional special equipment, without limitations imposed by types of component members and/or manufacturing conditions and at a high level of productivity and to provide the support frame and the display panel using the support frame. It is a second object of the present invention to provide the method for manufacturing the support frame of the display panel which is capable of preventing EMI, insulating circuits, or positioning the display panel in small component counts and in small numbers of processes and to provide the support frame and the display panel using the support frame.

wherein end portions of the first and second component members are fitted and coupled by placing the convex portions and the concave portions in such a manner that the shear droop of each of the convex portions faces the burr of each of the concave portions and the burr of each of the convex portions faces the shear droop of each of the concave portions.

In the foregoing, a preferable mode is one wherein each of the convex portions and the concave portions has an approximately trapezoidal configuration.

According to a seventh aspect of the present invention, there is provided a display device equipped with a support frame which supports a rectangular display panel and a portion surrounding the rectangular display panel described above.

With the above configuration, a plurality of component members each having convex portions and concave portions arranged alternately at an end portion of each of the plurality of component members in a manner that each of the convex portions and the concave portions is bilaterally symmetrical, while a shear droop and a burr are formed at each end portion of each of the plurality of component members is taken from a plate material. Next, the convex portions making up an end portion of one of the plurality of component members to be used for assembling and the concave portions making up an end portion of another of the plurality of component members to be used for assembling are placed in such a manner that the shear droop of each of the convex portions faces the burr of each of the concave portions and the burr of each of the convex portions faces the shear droop of each of the concave portions and that a force is applied so that the convex portions and the concave portions are pushed towards each other and by pressing the convex portions and the concave portions in upward and downward directions using a pair of metal molds on which projected portions are formed on a surface of one of the metal molds in a position being apart by a specified distance from an end portion of two of the component members out of the plurality of component members or from an end portion of one of the plurality of component members. As a result, end portions of the plurality of component members are fitted and coupled. Therefore, a support frame of a rectangular display panel can be manufactured within short working time, without use of special equipment, without limitations imposed by types of component members and/or manufacturing conditions and at a high level of productivity.

With another configuration as above, a component member made of a metal out of a plurality of the component members each having the convex portions and the concave portions arranged alternately at an end portion of each of the plurality of component members in a manner that each of the convex portions and the concave portions is bilaterally symmetrical and making up the support frame by being assembled, while a shear droop and a burr are formed at each end portion of each of the plurality of component members is taken out from a plate material and, in the case where the plurality of the component members to be assembled in combination is made up of component members made of a same metal or made of a different metal, the convex portions making up an end portion of one of the plurality of component members and the concave portions making up an end portion of another of the plurality of component members placed in such a manner that the shear droop of each of the convex portions faces the burr of each of the concave portions and the burr of each of the convex portions faces the shear droop of each of the concave portions and that a force is applied so that the convex portions and the concave portions are pushed towards each other and by pressing the convex and concave portions in upward and downward directions using a pair of metal molds on which projected portions are formed on a surface of one of the metal molds in a position being apart by a specified distance from an end portion of two of the component members out of the plurality of component members or from an end portion of one of the plurality of component members and, in the case where the plurality of the component members to be assembled in combination is made up of a first component member made of a metal and a second component member made of a resin, the convex portions making up an end portion of the first component member and the concave portions making up an end portion of the second component member placed in such a manner that the shear droop of each of the convex portions faces the burr of each of the concave portions and the burr of each of the convex portions faces the shear droop of each of the concave portions and that the end portion of the first component member is pushed toward the end portion of the second component member and by pressing the convex and concave portions in upward and downward directions using a pair of metal molds on which projected portions are formed on a surface of one of the metal molds in a position being apart by a specified distance from the end portion of the first component member, thus causing end portions of the plurality of component members to be fitted and coupled. Therefore, it is possible to take countermeasures against EMI and/or to insulate circuits in small component counts and in small numbers of processes.

FIG. 2 is an expanded view illustrating the fitting/coupling section 22 only. In FIG. 2, a diagram on a left side shows an expanded view of an A portion of FIG. 1 and a diagram on a right side shows an expanded view of a B portion of FIG. 1. The trapezoidal each of convex portions 22 aand 23 a(not shown in FIG. 2) and trapezoidal concave portions 22 band 23 b(not shown in FIG. 2) is preferably bilaterally symmetrical when easiness in assembling and in fitting and coupling, strength of a display frame to be obtained after fitting and coupling processes, or a like are taken into consideration. Moreover, a size of each of the trapezoidal convex portions 22 aand 23 aand of trapezoidal concave portions 22 band 23 bthat is, a length of each of the trapezoidal convex portions 22 aand 23 aand of trapezoidal concave portions 22 band 23 bin a direction orthogonal to an end face of an end portion of each of the L-shaped component members 21 aand 21 bserving as a portion for fitting and coupling between the L-shaped component members 21 aand 21 bis, for example, 2.0 mm. Furthermore, in each corner portion of each of the trapezoidal convex portions 22 aand 23 aand trapezoidal concave portions 22 band 23 ba portion having a radius R is formed. The radius (R) is, for example, 0.1 mm. A portion having the same radius as above is formed in each of the trapezoidal convex portions 22 aand 23 aand the concave portions 22 band 23 bdescribed hereafter.

Next, a method for fabricating the front frame 21 will be described below. First, a method for fabricating the L-shaped component members 21 aand 21 bthemselves is explained. As a material for the L-shaped component members 21 aand 21 bstainless steel is preferably used from a point of easiness in processing. Punching is performed, using a pressing machine, on a belt-shaped stainless steel plate material 24 being wound into a roll to produce the L-shaped component members 21 aand 21 b. At this point, as shown in FIG. 3, between a lower metal mold 25 and an upper metal mold 26 both being used to perform punching on the belt-shaped stainless steel plate material 24 is provided a clearance “t” having a width being equal to about 12% of a thickness (for example, 1.0 mm) of the belt-shaped stainless steel plate material 24. The width of this clearance “t” is about two times larger than that (about 6%) employed in a normal case. As shown in FIG. 4, in an end portion of each of the L-shaped component members 21 aand 21 bobtained after the punching process, for example, in the convex portion 22 aof the L-shaped component member 21 a, are formed a shear droop 27 which is a small part of an end portion of the L-shaped component member 21 ahanging down from a surface of the L-shaped component members 21 aand a burr 28 having a width being equal to about 10% of the thickness (for example, 1.0 mm) of the belt-shaped stainless steel plate material 24, which is a small part of the end portion of the L-shaped component member 21 aoverhanging from a surface of the L-shaped component members 21 a.

Next, as shown by arrows in FIG. 6B, while a force (pressure) is being applied to both the L-shaped component members 21 aand 21 bSO that both end portions of the L-shaped component members 21 aand 21 bare pushed towards each other, the upper metal mold 30 is put on the L-shaped component members 21 aand 21 bwith force being applied to them from an upper direction. In this case, the force used for pushing the upper metal mold 30 is, for example, about 10 tons and time during which pressing is made by the upper metal mold 30 is, for example, about one second. Since each of the line-shaped projected portions 30 aand 30 bis provided with the portion having a radius, each of the line-shaped projected portions 30 aand 30 bcuts into each of the L-shaped component members 21 aand 21 b. As a result, a part of the L-shaped component member 21 abeing equivalent to a volume of the line-shaped projected portion 30 band the burr 28 move smoothly toward the shear droop 27 in the L-shaped component member 21 band the burr 28 cuts into the shear droop 27 in the L-shaped component member 21 b, while a part of the L-shaped component member 21 bbeing equivalent to a volume of the line-shaped projected portion 30 aand the burr 28 move smoothly toward the shear droop 27 in the L-shaped component member 21 aand the burr 28 cuts into the shear droop 27 in the L-shaped component member 21 a. Therefore, as shown in FIG. 6C, the convex portion 22 aand concave portion 22 bare fitted each other in a mechanical manner. At this point, each of the line-shaped projected portions 30 aand 30 bcut into each of upper surfaces of the L-shaped component member 21 aand 21 bon both sides of the fitting/coupling section and, as a result, grooves 31 and 32 each having an approximately V-shaped cross section are formed as shown in FIG. 6C. After the processes shown in FIGS. 6A, 6B, and 6C have been performed on the fitting/coupling section 23 between the L-shaped component member 21 aand 21 b, as in the case of the above second conventional example, by bending a bending margin of each side using a pressing machine, the front frame 21 having the same shape as the front frame 2 shown in FIG. 29 is manufactured. Moreover, a center frame having the same shape as a center frame 3 shown in FIG. 29 is also manufactured by approximately the same method as described above.

Also, according to the method of the first embodiment, since, in each of the fitting/coupling sections 22 and 23, the trapezoidal convex portions 22 aand 23 aand trapezoidal concave portions 22 band 23 bare provided, such the constricted portions 14 cand 15 cas employed in the above second conventional example are not incorporated, the front frame 21 can be precisely formed and can have high strength, irrespective of strength of the component members.

Next, as shown in FIG. 8B, while a force is being applied to the L-shaped component members 21 aand 21 bso that end portions of the L-shaped component members 21 aand 21 bare pushed towards each other, the upper metal mold 34 is put on the L-shaped component members 21 aand 21 bwith force being applied to them from an upper direction. In this case, the force used for pushing the upper metal mold 34 is, for example, about 10 tons and time during which pressing is made by the upper metal mold 34 is, for example, about one second. The line-shaped projected portion 33 acuts into the L-shaped component members 21 band the line-shaped projected portion 34 acuts into the L-shaped component member 21 a. As a result, since the portion having a radius R is formed in the line-shaped projected portion 33 a, a part of the L-shaped component member 21 bbeing equivalent to a volume of the line-shaped projected portion 33 aand the burr 28 move smoothly toward the shear droop 27 in the L-shaped component member 21 band the burr 28 cuts into the shear droop 27 in the L-shaped component member 21 bwhile, since the portion having a radius R is formed in the line-shaped projected portion 34 a, a part of the L-shaped component member 21 abeing equivalent to a volume of the line-shaped projected portion 34 aand the burr 28 move smoothly to the shear droop 27 in the L-shaped component member 21 band the burr 28 cuts into the shear droop 27 in the L-shaped component member 21 b. Therefore, as shown in FIG. 8C, convex portions 22 aand 23 aand concave portions 22 band 23 bare fitted each other in a mechanical manner. At this point, since the line-shaped projected portion 33 acuts into a lower surface of the L-shaped component member 21 band the line-shaped projected portion 34 acuts into an upper surface of the L-shaped component member 21 a, as shown in FIG. 8C, grooves 35 and 36 each having an approximately V-shaped cross section are formed in a position being approximately symmetric with respect to a point in the fitting/coupling section 22. Next, after the processes shown in FIGS. 8A, 8B, and 8C have been performed on a fitting/coupling section 23 between the L-shaped component member 21 aand 21 b, as in the case of the above second conventional example, by bending a bending margin of each side using a pressing machine, the front frame 21 having the same shape as the front frame 2 shown in FIG. 29 is manufactured. Moreover, a center frame having the same shape as a center frame 3 shown in FIG. 29 is also manufactured by approximately the same method as described above.

The front frame 41 of the third embodiment is assembled so as to have an approximately □-shaped configuration and is made up of an approximately -shaped component member 42 amaking up its upper portion, an approximately I-shaped component member 42 bmaking up its right side portion, and an approximately L-shaped component member 42 cmaking up its left side portion and its lower portion. A fitting/coupling section 43 having trapezoidal convex portions 43 aand trapezoidal concave portions 43 bis provided at a place where the -shaped component member 42 ais coupled to the approximately L-shaped component member 42 c, a fitting/coupling section 44 having trapezoidal convex portions 44 aand trapezoidal concave portions 44 bis provided at a place where the -shaped component member 42 ais coupled to the approximately I-shaped component member 42 band fitting/coupling section 45 having trapezoidal convex portions 44 aand trapezoidal concave portions 44 bis provided at a place where the approximately I-shaped component member 42 bis coupled to the approximately L-shaped component member 42 c. FIG. 10 is an expanded view explaining the fitting/coupling section 45 only. In FIG. 10, a diagram on a left side is an expanded view of an A portion of FIG. 9 and a diagram on a right side is an expanded view of a B portion of FIG. 9. In FIGS. 9 and 10, each of the trapezoidal convex portions 43 a, 44 a, and 45 aand trapezoidal concave portions 43 b, 44 b, and 45 bis preferably bilaterally symmetrical when easiness in assembling, in fitting and coupling and, strength of a display frame to be obtained after the fitting and coupling processes have been performed are taken into consideration.

Next, a method for fabricating the front frame 41 will be explained below. First, a method of fabricating the -shaped component member 42 a, the I-shaped component member 42 b, and the L-shaped component member 42 cthemselves is explained. As a material for the component members 42 band 42 cother than the -shaped component member 42 a, stainless steel is preferably used from a view point of processing. On the other hand, since TCPs 6 1to 6 8and/or printed board 4 (see FIG. 29) are disposed below the -shaped component member 42 a, as a material for the -shaped component member 42 a, a metal having high conductivity such as copper, aluminum, iron, or a like is used, in order to prevent EMI. FIG. 11 shows specific conductivity of each of materials at a frequency of 0 to 150 kHz when conductivity of copper (5.5×107s/m) is defined to be 1 (one). As the material for the -shaped component member 42 ain addition to copper, aluminum, or iron, galvanized iron being generally used as a shielding material may be employed. Punching is performed, by using a pressing machine, on a belt-shaped plate material 24, being wound into a roll, made of stainless steel, copper, aluminum, iron, or galvanized iron to produce the -shaped component member 42 a, the I-shaped component member 42 b, and the L-shaped component member 42 c. At this point, as shown in FIG. 12, between a lower metal mold 25 and an upper metal mold 26 both being used to perform punching on the belt-shaped plate material 24 is provided a clearance “t” having a width being equal to about 12% of a thickness (for example, 1.0 mm) of the belt-shaped plate material 24. The width of this clearance is about two times larger than that (about 6%) employed in a normal case. As shown in FIG. 13, in an end portion of each of the -shaped component member 42 a, the I-shaped component member 42 b, and the L-shaped component member 42 c, for example, in the convex portion 44 a, are formed a shear droop 27 which is a small part of an end portion of the belt-shaped plate material 24 occurring after being punched and hanging down from a surface of each of the -shaped component member 42 a, the I-shaped component member 42 band the L-shaped component member 42 cand a burr 28 having a width being equal to about 10% of the thickness (for example, 1.0 mm) of the belt-shaped plate material 24 which is also a small part of the end portion of the belt-shaped plate material 24 occurring after being punched and overhanging from a surface of each of the -shaped component member 42 a, the I-shaped component member 42 b, and the L-shaped component member 42 c.

Next, as shown by arrows in FIG. 15B, while a force is being applied to each of the -shaped component member 42 aand the L-shaped component member 42 cso that end portions of the -shaped component member 42 aand the L-shaped component member 42 care pushed towards each other, the upper metal mold 30 is put on the -shaped component member 42 aand the L-shaped component member 42 cwith
