Abstract

PURPOSE: To produce a drawing-molded product for use in containers being light and excellent in a bottom strength, by a method wherein the generation of creases is prevented in a drawing process, and the shape is protected from being deformed in a molding process for reinforcing by imparting rugged surface and in a punch-extracting process.
CONSTITUTION: A punch 1 and a blank holder 9 are lowered, blanking of a material 23 being performed by means of a cutter 11 just in prior to bring a lower surface 9a of the holder into contact with the flexible material 23 placed on a dice 16b. A crease-pressing force is approximately simultaneously applied on the material 23 by means of a cushion pin 12 and the holder 9. When it begins to be molded with the punch further lowered, the material being drawn such that it is pressed against a cylindrical portion 1b made of an elastic material by a dice shoulder curvature portion 16a, whereby the generation of creases can be prevented. An rugged surface is provided on a bottom 25a of the drawing-molded product as a result of the bottom being pressed between a bottom surface 1e of the punch and an upper surface 24a of a tool. Since the drawing-molded product 25 presses a flange 25b against the holder 9 and is fastened thereat, the drawing-molded product 25 is prevented from being deformed in the shape due to returning of the cylindrical portion to the original shape thereof. Furthermore, since pressured air is fed into the molded product through a punch perforation 1c, the shape can also be protected from being deformed due to the reduction in the pressure.
