Abstract

PURPOSE: To prevent the surface of a product from getting rough, by carrying out bending working of band metallic material with U-section, pressing it in the direction of thickness by use of one pair of opposed form punches and dies.
CONSTITUTION: On the material setting part 21a which has been finished to a mirror surface, of the straight dies 21 is placed the material W in a free state. The upper dies 10 are lowered by operating a proper lifting means, and the lower top part of the form punches/11 is made to contact the upper surface of the material. When the upper dies approach the lower dies 12, one pair of dies holders 19, 19 are turned in such a way as they are opened downwards centering around the shaft 20, and also the straight dies are slided along the external circumferential face of the punches by the distance corresponding to the difference of turning displacement of the dies holders and length of the belt 22, and the material is bent by pressure. Accordingly, since the mateial dilates and deforms the whole surface, being affected by the load in the direction of thickness, it is molded with a good finished surface without causing wrinkles and flows.
