Punch Retaining Device

US Patent:
4688459, Aug 25, 1987
Filed:
Nov 14, 1985
Appl. No.:
6/797842
Inventors:
Wayne L. Osborn - Emporia KS
Monty L. Neff - Emporia KS
Assignee:
Didde Graphics Systems Corp. - Emporia KS
International Classification:
B26F 108, B26F 114
US Classification:
83698
Abstract:
A punch assembly is provided wherein individual punches may be quickly released and extracted from a punch ring by depressing an elongated retainer member positioned adjacent and transverse to each of the punches. The retainer member has walls defining a concave groove, and the retainer walls are selectively engageable with complemental, groove-defining walls of each punch. A spring normally biases the retainer member to a position where the retainer walls tightly engage the punch walls and thereby retain the punch within a bore of the punch ring. When the punch must be removed from the ring for repair or replacement, the retainer can be depressed against the bias of the spring and shifted to a position wherein the groove-defining retainer walls disengage the groove-defining punch walls, thereby enabling the release of the punch from the punch ring.
