Abstract

PURPOSE:To improve the accuracy of forming and to reduce the cost by forming a material palte to be U-shaped and forming the bottom thereof into the flat surface parallel to a raw material plate to be T-shaped or L-shaped. CONSTITUTION:A raw material plate 4 is formed into a U-shaped form by press forming metal molds 6, 7. The U-shaped form 5 is press formed into a form 3 T-shaped or L-shaped in section as an oblong engaging portion 1, in such a manner that with the base portions 9, 9 of the U-shaped form 5 left as they are, portions 12 outside a portion 11 corresponding to an opening portion 10 are substantially closely overlapped.

Description

[Detailed description of the invention]

This article relates to a gum manufactured by press molding as a blank plate for holding an article, ff4 flat metal plate t, having the shape of the following item tIJ. As shown in Fig. 1 and Fig. 2, there is a T-shape on the I# surface that continues along the entire length of the IAI in the width direction of the panel surface.
(Fig.) Also, the #-1tL-shaped (Fig. 2) horizontally elongated locking portions (1) are arranged parallel to each other in a highly distributed densely connected manner to the panel body, 21

However, it is inevitable that the raw board will undergo extremely large deformations and severe distortions, such as P%9. The deformation caused by t/res de ameto,/...'' is small and gentle.Moreover, it has a U-shape in the shape of C4 at the L root, and in addition to this, the final form C4 is U-shaped. The basic 1-bi, rimari 1-hand and L-shaped conversions ($ line) with j in the shape of a tuft or L-shape ($ line)-f make the conversion of 7 easy and good. This is a preliminary form that is unlikely to be implemented. Therefore, it can be press-formed into a predetermined T-shape or L-shape while primarily preventing distortion and cracking. As described above, the method of the present invention makes it possible for the first time to carry out press forming of a spring for holding an article with the shape described in item II above. (a) It has greatly contributed to the promotion of mass production and cost reduction based on sheet metal presses, and (b) Moreover, it has produced high quality products with no distortion or cracks in the horizontally long locking parts. It is possible to do this. Next, I will explain the uninvented embodiment.

In this case, the movement control of the mold becomes complicated, but the installation space is reduced, and the feeding process of the blank plate (4) is reduced by half compared to the example of No. 1.8g.
