Abstract

PURPOSE:To provide a titled structure for fixing a punch pin which improves the ease of the operation for attaching and detaching the punch pin by fixing the punch pin to the upper die of a press by means of a punch pin holder having the diameter larger than the diameter of the punch pin and screwing said holder to the upper die. CONSTITUTION:A punch pin 50 and a punch pin holder 58 having the diameter larger than the diameter of said pin are connected by means of a connecting member 74. More specifically, a member 74 is inserted into the insertion hole 62 of the holder 58 and at the same time the top end of a hexagon wrench 86 is inserted into a tool mounting groove 84 of the member 74 then the wrench 86 is turned to connect the pin 50 and the holder 58. After the top end of the pin 50 is inserted via a hole 42 into a punch pin insertion hole 30, a hexagon wrench 72 mounted in a tool mounting groove 66 via the hole 42 is turned to screw a groove 32 and a groove 56 thereby fixing the pin 50 to a punch pin fixing part 28. The work 22 on a lower die 16 is trimmed by such pin 50. When the top end of the pin 50 is bent, the operator separates an upper platen 10 from an upper die 12, inserts the top end of the wrench 86 into the groove 84 of the member 74 and releases the screwing of the pin 50 by turning the wrench 86.

A threaded groove is formed on the outer circumferential surface, and a through hole that penetrates approximately the center in the radial direction along the axial direction of the punch pin holder and a tool mounting groove that communicates with this through hole and has a larger diameter than this through hole are formed. A tool mounting groove is formed on the head end surface of the fastening member, which is arranged in parallel and can be screwed into the thread groove of the bunch pin, and which passes through the through hole of the punch pin holder and projects from the end of the through hole. Since the punch pin and the punch bin holder are attached and detached, and the punch bin holder and the bunch pin fixing part are attached and detached using the tool attachment groove and the attachable tool, the workability of the punch pin attachment and replacement work is improved. It has the excellent effect of improving the
