DESIGN & FABRICATION OF PROGRESSIVE DIE FOR MAKING WASHER
Main Article Content
Abstract
The process of designing and fabrication of progressive die set for making washer, methods and techniques are required which improve the efficiency and productivity of manufacturing product, large scale and higher speed requires helper tool known as press tool. Manufacturing of Washer is accompanied by two types of press tool operation namely blanking, piercing .Itis a metal stamping operation in which the sheet metal is punched to get the needed outer profile of the sheet metal component. During the blanking process, the blanking punch penetrates into the sheet metal & forces the material into the blanking die. The portion of the sheet metal which coming out through the blanking die opening is the component with the demanded profile. Piercing operation made up of simply hole punching. It differs from blanking such that the punching is the scrap and the strip is the work piece. Piercing is nearly always accompanied before the blanking operation, after or else at the same time.
