ABSTRACT:
In accordance with the present invention, a punching assembly is provided which includes a punch slidably mounted in a housing. An air chamber is located between the punch and the housing for air cooling the punch, with means associated between the housing and the punch for automatically transferring air into the chamber in response to the reciprocation of the punch in the housing. The punch has a flange with a sliding fit in the housing to define a piston for changing the volume of the air chamber. In accordance with another feature of the invention, the stripper plate is removable and is automatically locked in place when inserted, i.e., it is self-locking.
