ABSTRACT:
A stripper apparatus retains a workpiece in position relative to a punch press apparatus during the punching operation without marking or damaging a contacted surface of the workpiece. The stripper device is an axially elongate, resiliently compressible sleeve with a through axial bore which freely passes over the punch permitting the punch to travel therethrough. The stripper device removably attaches to a coupler or coupling portion which is also used to attach the punch to a punch stem of the punch press apparatus. Removable attachment is achieved utilizing keyways formed in the coupling portion and matingly engagable keys integrally formed on a corresponding surface of the stripper device. Additionally, peripheral flanges are integrally formed on the stripper which mate with the outside surface of the coupling portion to provide greater retention of the stripper device on the coupler. The stripper device eliminates the need for numerous stripper and punch combinations and permits easy removal of the stripper device from the coupler when necessary.
