As the press ram descends the pressure pads make
contact with the die plate driving the die and part downward in a vertical motion. At the
same time a series of cams drive the die and part horizontally toward the punch from four
directions. This action causes the scrap material to be sheared from inside toward the
outside of the part leaving virtually no burr on the outside. After trimming, the part and
scrap can be air ejected out of the die.
This method of trimming gives you a clean sheared edge leaving 100% material
thickness at the trimline. Overall height tolerances from the inside of the part can
normally be held within a few thousandths of an inch.
Standard dies can be used in almost any type of press. Our die requires the use of
an air cushion but if one is not available we can supply a die with a built in cushion.
In many cases the shimmy die process has been able to eliminate several
manufacturing operations. Our ability to trim and notch in one stroke can save you
excessive handling and labor. |
