A Study on the Design of Compound Die with Constant Blank Holder Pressure
This paper introduces blanking, drawing and compound die of the cylindrical parts. The compound die applies the special structure to maintain a constant blank holder pressure, which is not increased by drawing. It reduces the processes and improves the efficiency of production.
