If the box 1 is assembled from a metal plate, if the concave-concave handle portion 2 can be drawn by stamping, the number of manufacturing steps and the cost can be reduced, which is advantageous.

ばならない。Usually, the drawing of the drawn portion such as the handle portion 2 is performed by one-time stamping. However, as shown by the arrow in FIG. 8, in the case of a metal plate (blank) 6 which is particularly poor in drawability due to its material and has only a slight elongation, forming the draw part 7 into a predetermined shape means This is possible by transferring the meat of the portion 8 to the narrowed portion 7. However, when sufficient elongation of the material cannot be obtained in the peripheral portion 8 of the narrowed portion 7, for example, when the narrowed portion 7 is far from the edge of the metal plate 6, the narrowed portion 7 is cracked 11 as shown in FIG. Will occur. In addition, even if the narrowed portion 7 is formed so as not to cause the crack 11 as described above in the product specifications, the meat of the peripheral portion 8 is pulled by the depth of the narrowed portion 7, so that the drawing As shown by the comparison between the two-dot chain line and the solid line in 8,
The outer shape of the metal plate 6 is greatly distorted, and as it is, the value as a product is lost. On the other hand, in order to obtain a product, the metal plate 6 must be punched and cut into a predetermined shape as shown by the one-dot chain line a in FIG. 8, but this will increase the number of steps and the yield. Further, as shown in FIG. 10, wrinkles 12 may occur in the portion 8 around the narrowed portion 7. Further, as shown in FIG. 9, in the metal plate 6, by forming a relief portion 13 such as a hole or a notch line in advance in a portion 8 around the area to be the narrowed portion 7, cracks 11 and wrinkles can be formed. It is possible to form the drawn portion 7 without generating 12, but the relief portion
13 is unnecessary as a product, so to get a product,
Again, the metal plate 6 must be cut as indicated by the one-dot chain line b.

することが困難である問題があった。As described above, in the past, the drawn portion was formed by one-time stamping, so that the drawn portion is cracked in the case of a metal plate having poor extensibility or when the drawn portion is deep. However, there is a problem that it is difficult to form the drawn portion without causing distortion and wrinkles or the like in the peripheral portion of the drawn portion.

The shallow drawing portion has a drawing amount smaller than that of the drawing portion to be finally formed, and does not cause breakage of the metal plate. Then, the drawn portion is drawn into a predetermined shape by stamping, and at that time, the shallow drawn portion is crushed and stretched.However, due to the elongation of the metal plate by the above-mentioned shallow drawn portion, the elongation necessary for forming the drawn portion has already been increased. It is secured to some extent. Therefore, even in the case of a metal plate having poor extensibility, even when the narrowed portion is deep, without causing cracks in the narrowed portion or causing distortion or wrinkles in the peripheral portion of the narrowed portion, The narrowed portion will be molded.

At the time of draw forming, first, as shown in FIGS. 1A and 2A, a flat metal plate 31 having a predetermined shape is mounted on the lower mold 21. Then, as shown in FIGS. 1 (b) and 2 (b), the first punch 25 feeds one stage to form a plurality of shallow drawn portions 32 on the metal plate 31. Then, another step is sent,
By the second punch 26, the drawn portion 33 having a predetermined shape is superposed on the shallow drawn portion 32 on the metal plate 31 and drawn. At the time of stamping, the die 22 and the pressing plate 24 are used to form a portion 34 around the shallow drawn portion 32 or the drawn portion 33 in the metal plate 31.
When the punches 25 and 26 are pressed from above by the metal plate 31 in a state where the punches are sandwiched and pressed, the shallow drawn portion 32 or the drawn portion 33 is drawn. Particularly, when the narrowed portion 33 is formed, the metal plate 31 is sandwiched and pressed between the die 22 in the second recess 28 and the lower end portion of the second punch 26.

The plane shape is a parallel straight line shape, and the cross-sectional shape is a wavy shape. Further, the drawing amount of the shallow drawn portion 32 is smaller than that of the drawn portion 33, but it should be as close as possible to the limit of ductility of the material of the metal plate 31. At the same time, the plurality of shallow drawn portions 32 are formed in almost the entire area c of the metal plate 31 which will be the drawn portions 33. In this way, by forming the shallow drawn portion 32, the region c of the metal plate 31 that becomes the drawn portion 33 is
It can be stretched to the limit of the extensibility of 31 materials. Then, in the subsequent molding of the drawn portion 33, the shallow drawn portion 32 is crushed and stretched. Incidentally, it is desirable that the surface of the drawn portion 33 becomes smooth as shown in FIG. 4 along with the forming of the drawn portion 33 by the stamping, but as shown in FIG. If the unevenness of the trace 32a of the diaphragm 32 remains, if necessary, repeat stamping, etc.
33 Finishing to smooth the surface is added.

ある。As described above, at the time of forming the drawn portion 33 by stamping, first, the plurality of shallow drawn portions 32 having a smaller drawing amount than the drawn portion 33 are drawn to form the metal plate 31.
When the region c which will be the narrowed portion 33 is extended, and then the shallow narrowed portion 32 is crushed and stretched to draw the originally intended narrowed portion 33, a metal plate 31 having a hard and poor ductility such as an aluminum-plated steel plate is obtained. Even if there is, or even if the throttle portion 33 is deep, it may cause cracks in the throttle portion 33,
The squeezed portion 33 can be molded without causing distortion or wrinkles in the peripheral portion of the portion 33. This is because the elongation of the metal plate 31 due to the forming of the shallow drawn portion 32 is applied to the forming of the drawn portion 33. Of course, the drawing amount of each of the shallow drawn parts 32 is such that the metal plate 31 is not broken, but the plurality of shallow drawn parts 32 as a whole ensure the elongation necessary for forming the drawn parts 33. Is there. In the present embodiment, the surface area of the entire shallow throttle portion 32 is about the surface area of the throttle portion 33.
100 to 110%. Then, the influence of the molding of the narrowed portion 33 on the surrounding portion 34 can be reduced, the movement of the meat in this portion 34 can be reduced, and the strain generated in this portion 34 can be reduced. As a result, the drawn portion 33 having an arbitrary shape can be formed at an arbitrary position on the metal plate 31, and moreover, the metal plate 31 can be directly manufactured without being subjected to a post-treatment such as cutting. Also, the manufacturing is easy because it requires a two-step pressing process.
