Patent
CA 2268636
A noise-reducing structure of a processing machine reduces the noise generated when a movable member of the processing machine abuts against a workpiece located on a workpiece holder of the processing machine. The processing machine may be a drawing die including a punch, a blank holder fitted around the punch and a vertically movable die disposed to face the punch. The workpiece may be a thin plate which is placed on the blank holder. As the die is lowered, the thin plate is sandwiched between the blank holder and the die. A lower die base plate is provided with a pivotable lever member for pushing the blank holder so that the blank holder begins movement before the die collides against the thin plate. An operation cam for driving the lever member is disposed at a position on the die facing the lever member, and the die collides against the thin plate on the blank holder after the blank holder is in motion.
