MISFEED PREVENTING APPARATUS FOR PROGRESSIVE MOLD

摘要

A miss feed detecting apparatus of the progressive mold in which the guide punch pin interval is connected in the progressive mold which at the same time, makes the end type terminal strap more than 2 rows. A miss feed preventing apparatus of the progressive mold comprises a lower holder(10) in which the lower retainer(14) in which the die(15) is installed; an upper holder(20) is equipped in the upward of the lower holder and relatively going up and down about the lower holder and is formed so that the penetration hole in which elastic members(25,48) is settled while an upper retainer(40) is equipped be penetrated; a plurality of guide punch pins(50) which the one end is supported by the elastic member, and a pin hole(52) is formed and the other end fixes one side of the workpiece settled in die; a key block(60) which unites so that two guide punch pins which are positioned between the guide punch pin and are adjacent be together ascended and descended; and a switch operated with a coupling bar(45) connected with the operation of the guide punch pin overcoming the elastic force of the elastic member.
