PUNCH HOLDER AND PUNCH CONFIGURATIONS

摘要

Punch holders and corresponding punch configurations configured to increase the ease and speed by which maintenance and/or modification of punches used with the holders can be performed. In some cases, the punch holder can be configured with one or more upper and lower collars operatively situated on differing areas of the holder, with each collar adapted to perform a different action with regard to a punch held by the holder. In some cases, when the upper collar is rotated, a corresponding height adjustment of a punch held by the holder results. In some cases, when the lower collar is rotated, a punch held by the holder is released.

1. A punch holder comprising:
an upper portion and a lower portion, the upper portion comprising head unit for the punch holder and the lower portion comprising punch coupling unit for the punch holder, the upper portion operably coupled yet selectively adjustable relative to the lower portion; a first collar encircling a lateral extent of the upper portion, the first collar being movable in position relative to the lower portion, whereby movement of the first collar provides a corresponding adjustment in overall height of the punch holder; and a second collar encircling a lateral extent of the lower portion, the second collar being movable in position relative to the lower portion, whereby movement of the second collar corresponds to a shift from a locked configuration to an unlocked configuration for the lower portion relative to a punch held thereby.
