WEAR TOLERANCE INDICATOR FOR STAMPING DIES

摘要

A stamping die includes an upper die member, a lower die member, and at least one guidance member operably disposed to guide relative movement between the upper and lower die members. The members are movable relative to one another in reciprocating motion along an axis to generate work-pieces. The guidance member has a guiding surface for guiding relative movement between the die members. The guidance member also has at least one wear indicator cavity recessed from the guiding surface. A depth of the wear indicator cavity corresponds to the extent of acceptable wear of the guiding surface. The cavity allows for visual inspection of the extent of wear of the at least one guidance member and thus obviates the requirement that the guidance member be removed from the stamping die for inspection.

1. A stamping die comprising:
an upper die member; a lower die member, the upper and lower die members movable relative to one another in reciprocating motion along an axis to generate work-pieces; and at least one guidance member having a guiding surface operably disposed to guide relative movement between the upper and lower die members and having at least one wear indicator cavity recessed from the guiding surface, wherein a depth of the at least one wear indicator cavity from the guiding surface corresponds to an extent of acceptable wear of the guiding surface such that the at least one wear indicator cavity allows for visual inspection of the extent of wear of the at least one guidance member while the at least one guidance member is operably disposed on the stamping die.
