ABSTRACT:
A pierce cam is compact, can save space, can be easily mounted, can reduce cost, can even be mounted to a sloped surface, and a pierce punch and required accessories can be ordered in bulk from a single source. A pierce cam includes a pierce punch, a body which is detachably provided with the pierce punch, a stripper which is fitted to the pierce punch inward of a leading end portion of the pierce punch and is biased by a coil spring in a direction away from the body, a rotating arm which is swingably mounted on the body and is movable into contact with a rear end surface of the pierce punch, and a driver which transfers a descending force of a press machine to the rotating arm, and hooks and ascends the rotating arm at the time of moving upward.
