Abstract

A punch guide assembly is provided for removably carrying a stripper plate. The punch guide assembly comprises a punch guide and a stripper plate guide movable axially with respect to the punch guide. The stripper plate guide has a locked position wherein the stripper plate is secured to the punch guide assembly and an unlocked position wherein the stripper plate can be readily removed from the punch guide assembly. The stripper plate guide is resiliently biased axially toward its unlocked position yet is restrained against axial movement relative to the punch guide when in its locked position.

Description

technical field [0001] The present invention relates generally to punch guides, such as punch guides used with industrial punching presses. More particularly, the present invention relates to stripper plate retention assemblies for punch guides and the like. Background technique [0002] Multi-station hexagonal punching machines can provide up to 72 different punch stations for use with the same number of opposing dies. In such machines, each punch station serves as a punch set holder for a removable punch set comprising a centrally arranged punch ( punch), the punch is surrounded by a punch guide and biased by a punch spring. Despite the flexibility offered by the 72-desk, operators may wish to change some or all punch and die combinations from time to time. For example, an operator may wish to use different punch tip shapes or sizes within a punch set. It is desirable to minimize the time required and to be able to simply change the composition of the punch and die in ...
