ABSTRACT:
A punch retainer which, in one preferred form, includes at least one bolt head seat formed in the retainer's body for receiving a bolt by which the retainer is fixed to a punch press's mounting plate. The seat is defined in the retainer's bottom face adjacent a peripheral side wall, and a section of the peripheral side wall is removed from the retainer's body to provide access to the seat in a direction generally parallel to the plane of the retainer's bottom face. The punch retainer, in another preferred form, includes a backing plate and a body. A method of assembling this latter punch retainer with a punch press' mounting plate includes press fitting a registration dowel in assembled relation with the retainer's backing plate and body in a tight press fit relation so as to connect firmly the backing plate with the body. If a piercing punch with a circular shaped nib is selected for use with the retainer, that registration dowel can simply be driven wholly into the retainer while maintaining the interconnection between the retainer's backing plate and body. If a piercing punch with an irregular shaped nib is selected for use with the retainer, then the registration dowel is kept extended from the retainer's backing plate for interfit with a registration hole in the press' mounting plate. This method prevents the need for welding or adhering or bolting or otherwise connecting the retainer's backing plate with the retainer's body, and the registration dowel provides a double function when a punch with irregular shaped nib is selected for use.
