Design Of Dies For Sheet Metal Operation

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.

Design of dies for sheet metal operation.

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. So let me give you the overview of these dies. Sheet metal forming processes and die design second edition is the long awaited new edition of a best selling text and reference. Titlesheet metal forming processes and die design authorvukota boljanovic year2004 various die operations and performance evaluation shows the comparative advantages and liabilities for each.

This plate prevents the metal from wrinkling as it flows into the cavity. 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. Draw dies create the part shape by controlling metal flow into a cavity and over the forming punch. Under pressure the rubber and sheet metal are driven into the die and conform to its shape forming the part.
