Abstract

PURPOSE: To prevent the generation of an end roll-over and to improve a working efficiency by highly forming the edge part at the upper end of a die hole, forming a recessed part at the punching place of a clad material and arranging the upper end edge part of the die inside this recessed part.
CONSTITUTION: A recessed part 12 is formed by curving the punching plate of a clad material 1 to the opposite side to the punching direction. The upper end edge part 11 of a die fitting 9 is formed higher than the receiving face 10 of the clad material. A punch 7 and die fitting 9 are arranged in opposition pressurizably and the clad material 1 is mounted on the receiving face 10 of the die fitting 9 as well. In this state, the upper end edge part 11 of the die fitting 9 is arranged inside the recessed part 12 of the clad material 1. In succession, the punch 7 is descended to pressurize the opposite place of the recessed part 12 of the clad material 1, and the clad material 1 is clamped by the receiving face 10 of the die fitting 9 as well. The punch 7 is subjected to rolling reduction further, the lower face of the recessed part 12 of the clad material 1 is press-fitted to the upper end edge part 11 of the fitting 9 and the recessed part 12 of the clad material 1 is punched in the space with a die hole 8 to form a hole.
