Abstracts: A Hydraulic press is a machine using a hydraulic cylinder to generate a compressive force. Our college has a Hydraulic Press of 25 tonne capacity. We are designing a punch and die assembly to produce a Washer. The die we are using is a Compound Die that performs two functions : Blanking and Piercing. A blanking die produces a flat piece of material by cutting the desired shape in one operation. The finish part is referred to as a blank. Generally a blanking die may only cut the outside contour of a part, often used for parts with no internal features. The piercing operation is used to pierce holes in stampings. The ejection method that we used is a spring that will force the washer up after the operation.
