Abstract
PURPOSE: To prevent ocurrence of a crack and fissure at acute parts by arranging the counter holding member opposing to a punch and die, and setting up the pressure member for pressing the area nearby acute angle parts of the product against the counter holding member.
CONSTITUTION: After loading the material 5 on the lower counter holding member 18 and rising the ram, the material 5 is put between the upper counter holding member 19 and die 14, also punch 10 and lower counter holding member 18. When the ram further rises, the punch 10 goes into the material 5, and the rod 28 goes back to upward. While this process, the upper and lower counter holding members 19 and 18 are holding the material 5 with certain pressure. From the starting time of blanking, the pressing member 29 is pressed by means of the oil pressure piston pressed by pressure oil, and the ram is further rised, then blanking is completed.
