Abstract
The purpose of this invention is to standardize die shoes, which are the upper and lower portions of a fabrication die that supports the working portion of a die and punch. They are also used to mount the die into the stamping press. Standardization would reduce the die shoes into standard re-usable components which could be used year after year, which would reduce waste of material, plus allow interchangability between dies. Also, standardization will allow die shoes that can be changed to a larger shut height to suit larger die construction or larger presses. This feature will eliminate extra plates being added to dies when it is necessary to change the die to a larger press, which will improve safety. Standardization of die shoes amounts to breaking down the die shoes as commonly designed into standard components which can be reused and interchanged from die to die, press to press, year after year.
