Abstract
PURPOSE: To elude a material to the periphery and to prevent the roll-over of the peripheral side part of a parts by providing the projecting part corresponding to the peripheral side part of the parts punched from a blank on the reverse plate pressing body pressing the blank with the force in the reverse direction to the punch.
CONSTITUTION: When a blank 6 is fed onto a die 3 and a punch 4 is descended, a plate pressing body 5 is interlocked with the descent of the punch 4 to interpose the blank 6 with the die 3. Then, in the case of a part being punched from the blank 6, a reverse plate pressing body 9 is elastically press-fitted to the lower face side of the blank 6 to exert the force reverse direction to the punch 4 on the part where the part is punched. The projecting part 12 formed on the end face of the reverse plate pressing body 9 is then pressfitted to the lower face of the parts. Then, a recessed part is formed on the lower face of the parts by the projecting part 12 and the material in the same amt. as this recessed part is made to elude to the peripheral side part of the recessed part. Consequently, the roll-over caused on the parts peripheral side can de prevented.
