中央で切断できる。Therefore, during the drawing process, the support plate 20, which had been prevented from descending due to contact with the ridges of the sawtooth sections 59 and 60, is moved downward by the ram 47 further lowering the lower blocks 52, 53, upper blocks 55, 56, and the sawtooth sections. Following the drawing process of the upper die 12 guided by the guide tool 14 consisting of portions 59 and 60, the movable drawing die 3 is lowered diagonally downward at an angle of 45°, thus creating a groove shape between it and the stationary drawing die 2. The material W can be cut, for example, at the center of the drawing section A.

作業に比べて生産性を大巾に向上できる。As mentioned above, the mold of the present invention has a stationary drawing die and a movable drawing die adjacent to each other, and the movable drawing die is equipped with a guide for moving the drawing die obliquely. It is possible to draw the side pieces of the channel-shaped material and then cut it in one process, and to form a drawn part at each end of the channel-shaped material, instead of the conventional cutting and drawing in two steps. Productivity can be greatly improved compared to machining work performed on each end.
