A Novel Approach For Design Of Progressive Die For Sheet Metal Components

Design of progressive tools for the sheet metal component is one of the important phase in sheet metal manufacturing. Sheet metal press working process by progressive tools is a highly complex process that is vulnerable to various uncertainties such as variation in progressive tools geometry, strip layout, die shear, material properties, component and press working equipment position error and process parameters related to its manufacturer. These uncertainties in combinations can induce heavy manufacturing losses through premature die failure, final part geometric distortion and production risk. In this work the use of a software namely AUTOCAD and UG-NX for designing a progressive die to manufacture floating contact for the push button system has been incorporated. A progressive die is a multiple station die. In this work we have designed a progressive die which has four stages of operation. The operations are piercing, dimple forming, bending and then blanking. All these operations are performed simultaneously in a single stroke of press, thus enabling the user to obtain the final product in a single stroke.
