Abstract

PURPOSE: A producing device for corrugated ribs providing projections parallel to ribs on one surface of a die grasping the part near the curved part on both sides of the projectionlike ribs formed from a flat plate and which prevents the occurrence of elastic deformation, deviation in amplitude, etc. owing to the slip of the material.
CONSTITUTION: After a flat-plate-like material W is fed to the predetermined position on a die 2, a blank holder plate 3 is lowered to press and grasp the material W on a cover plate 2. In this case, the projectionlike ribs 1a to be formed and parallel projections 5 are provided to the cover plate 2; therefore, the grooves engaging the projections 5 are formed by these. Hence, the material W is so held in said groove parts as to prevent the movement in the lateral direction. Thence, an ejecting plate 4 is moved upward to cause the plate 3 to force the work W into the gap 3a, thereby forming the ribs 1a. As a result, the slip, etc. of the material W are eliminated and the accuracy of its working may be improved considerably.
