The prior art will be explained with reference to FIGS. 1 to 4. A curved flange R 1 as shown in Fig. 1,
The molding of parts R and L, each having L 1 , is carried out in the second
As shown in the figure, two parts R and L are cut out so that their respective flanges R 1 and L 1 face each other,
It was processed by bending flange R 1 upward and pressing flange L 1 downward at the same time, but the bending edge R 2 of the lower die for upward bending and the bending edge L of the upper die for downward bending were used. 2 , the thickness of the bending edges R 2 and L 2 must be increased.
Therefore, when cutting parts R and L, both parts R and L are
It is necessary to set the distance a between the opposing edges to a predetermined value or more to obtain bending edges R 2 ′, L 2 ′ that enable high-yield board cutting with the opposing edges in contact, as shown in Figure 3. I couldn't do it.

The press mold of this invention is characterized by sliding the back surfaces of opposing bending blades that operate in opposite directions. According to this configuration, each of the bending blades is The lateral pressure acting on the bending blade is offset by the back surface of the bending blade. Therefore, since the thickness of each bending edge can be made thinner, a single part with two flanges bent in different directions can be made with a narrow flange interval, and a single part with one flange can be made into two parts. For things that need to be trimmed, it is possible to produce boards with high yields.

持する方向に付勢されている。 The press die is composed of an upper die 1 and a lower die 2, and a lower bending blade 3 is attached to the upper die 1. On both sides of the lower bending blade 3, there are pads 4A for the lower bending blade and pads for the upper bending blade. 4B is supported so that it can move up and down. On the other hand, an upper bending blade 5 is attached to the lower mold 2, and a cushion 6A for lower bending and a cushion 6A for upper bending are provided on both sides of the upper bending blade 5, facing the pads 4A and 4B for lower bending and upper bending. A cushion 6B is disposed, and both cushions 6A and 6B are supported so as to be movable in the vertical direction in cooperation with the pads. The lower bending blades and upper bending blades 3 and 5 are arranged on the upper mold 1 and the lower mold 2 so that their back surfaces 3A and 5A move up and down while contacting each other. Each of the pads and cushions is made of an elastic body 7.

プされて加工時の前面からの圧力が相殺される。 Next, the operation of the above embodiment will be explained. The pressing force of the cushions 6A, 6B at the start of the molding process is made equal to the pressing force of the pads 4A, 4B. In the press die constructed in this manner, the upper die 1 is lowered and the cushions 6A, 6B and pad 4 are
When the workpiece a is held between A and 4B and the upper mold 1 is further lowered, the bending blade 5 of the lower mold 2 and the bending blade 3 of the upper mold 1 begin to process the workpiece a simultaneously,
The back surface 3A of the lower bending blade 3 and the back surface 5A of the upper bending blade 5 are in contact (see FIG. 5). Further, as shown in FIG. 6, when the upper die 1 is lowered further, the back surface 3A of the lower bending blade and the back surface 5A of the upper bending blade are sliding.
The upper bending blade 5 forms the upper bending flange a1 , and the lower bending blade 3 forms the lower bending flange a2 , and the processing is completed. As described above, according to the embodiment of the present invention, the back surface 3A of the lower bending blade and the back surface 5A of the upper bending blade contact and slide, thereby pressing the back surfaces against each other and being backed up and removed from the front surface during processing. pressure is canceled out.

Since this device is configured as described above, during the molding process, the back pressure applied to the lower bending edge of the upper mold and the upper bending edge of the lower mold is reduced by the back pressure of the bending blades that are sliding against each other. Since the thickness of the bending edge t
Sufficient strength can be obtained even if the plate is thin, the distance between the upper bent flange and the lower bent flange can be reduced, and the yield of board cutting can be increased.
