Design of dies for sheet metal operation.

In this article i will be exploring the 5 types of dies used in sheet metal operations at respective stages and strokes. This plate prevents the metal from wrinkling as it flows into the cavity. Draw dies create the part shape by controlling metal flow into a cavity and over the forming punch. In bending and embossing of sheet metal the female die is replaced with rubber pad rubber pad forming rpf is a metalworking process where sheet metal is pressed between a die and a rubber block made of polyurethane.

The different types of dies used in sheet metal operations are as follows. Draw dies utilize a special pressure loaded plate or ring called a draw pad or blank holder to control the metal s flow into the cavity. Under pressure the rubber and sheet metal are driven into the die and conform to its shape forming the part.

Different types of dies. The profiled sheet metal slug removed from the sheet by this process is called the blank or starting piece of sheet metal that will be cut or formed later see. Blanking a dual purpose cutting operation usually performed on a larger scale blanking is used in operations in which the slug is saved for further pressworking it also is used to cut finished piece parts free from the sheet metal.
