Connector for rigidly connecting punch tip to punch pad

摘要

A punch has a punch tip with a shank and a punch pad with an orifice for receiving the shank. The punch pad includes a hole positioned closely adjacent the orifice to define a thin wall between the hole and the orifice. The thin wall has a slot which extends through its thickness to define at least one, and preferably two, tabs. An insert, which may be a pin, is provided for insertion into the hole and deforming the tab into supportive, retaining contact with the shank of the punch tip within the orifice. The shank of the punch tip may be provided with a shoulder for abutting the inwardly deformed tab or tabs to restrain withdrawal of the punch tip from the punch pad during operation.
