Abstract

PURPOSE:To prevent tearing off phenomenon and heighten rigidity of a plate by eliminating the presence of a flange having facing direction that coincides with the direction of bending load at a place to be bent at the time of bending work. CONSTITUTION:Flanges 2, 2 are formed on both sides of a plate 1. On one side (a), the plate 1 is bent to become gently convex to the same direction with the direction of formation of the flange 2. Parts 3 corresponding to the flange are bulged out from the lower end of the flanges 2 to both outsides corresponding to decrement of the flange 2 caused by bending of the plate 1. Then, bending load is applied to the direction of arrow x and the plate 1 and the parts 3 corresponding to the flanges are bent making a line (l) as a bending line. Thus, a plate B on both sides of the position (a) is bent to intersect at right angles. The plate 1 is bent to a curved plate, and the flange 2 is worked to a bent flange.

Conventionally, the forming of the 7-flange was carried out by simultaneously bending the 7-lunge when obtaining a flat plate, but the flat plate and the flange formed on the side of the flat plate were Due to the nature of the lunges, their plane directions are different.If the bending load direction is set perpendicular to the plane direction of the flat plate body in order to bend the flat plate body, the bending cart direction will be 7. Since the direction is the same as the surface direction of the flange, the bending process of the flange is difficult, and the phenomenon of ``tearing due to wrinkles'' occurs in the flange.・A curved plate body and a bent 7-lunge are formed on the seam by applying seam processing.

However, in deep drawing, there is a limit to the depth of the drawing, so in addition to the problem of limiting the shape of the split product, deep drawing also requires punching at the same time. Therefore, in general molding that requires outline cutting, the outline cutting process must be carried out separately from the drawing process, which leads to the problem of an increase in the number of processes. It also had

Below, we will explain the processing procedures of the present invention and the conventional method (one based on the slow drawing process) for a more specific product (Figure 6).
! : I will briefly explain by comparing. First, in the present invention, in order to shape parts other than part a, shallow drawing and outline cutting are performed (Fig. 7), and all parts that were used as pad holding parts during the shallow drawing are removed. (Fig. 8) Cutting process for punching the holes on the plate part 1 (Fig. 8), and cutting and cutting the part A to make the shape (Fig. 6) 9. On the other hand, In the conventional method, deep drawing is applied to one part of A I/C.
2. The outside punching process is performed (Fig. 1O), the cutting process is performed on the part that was the pad holding part at the time of the external punching force, and the Taisei process is performed on the plate part 1 (Fig. 11), and The parts other than part a are bent to form seven flange 2 (see Figure 6).

In the present invention, the drawing process to obtain the shape of the metropolitan areas other than part a is not a closed drawing process, but a shallow drawing process to round/ζ-shaped (the presser is used at retail, and during the drawing process) Second, in the conventional method, in the processing process from the 1'JHO diagram to Figure 11, that is, the process in which cutting and Taisei machining are performed simultaneously, Since the key cutting direction is different from Taisei machining, a special type so-called six-cam structure is used.
Although there is a necessity to change 1 by 5, in the present invention, the series of machining is all performed in one direction (X direction, !: press machining related to a run whose direction is simply different from the Y direction). Therefore, in the case where the above-mentioned special mold is not cheap, in the present invention, the press processing for shaping one part a, that is, the processing from FIG. 8 to FIG. 6, is shown in FIGS. 12 to 14. The details will be explained based on the following.

First, with the press upper mold 4 positioned at its top dead center, the workpiece 16 is set on the lower mold cushion lO (Fig. 12) 9. At this point, the upper mold 4 is lowered; As the process progresses, the pad 9 is also bent, and the workpiece 16 is held between the pad 9 and the molded cushion 10. ,−
After t, the pad 9 is bent due to the deflection of the pad spring 7.
-rPi1! While the upper die 4 is stopped, the upper die 4 will continue to bend the workpiece 16 (Fig. 13). Due to the deflection of the lower mold cushion 12, the lower mold cushion 10 is lowered, and the workpiece 16 itself is lowered, so that the above-mentioned portion a is processed by the upper mold curved blade 6 and the lower mold curved blade 14. FIG. 14 shows the bottom dead center state of the upper mold 4, that is, the state at the time when processing of the workpiece 16 is completed.
