Title Stamping die design and forming simulation of the   Automobile parts

Abstract

The sheet metal parts is widely used in automobiles, this topic researches on designing a stamping die for automobile sheet metal structure . First design the method of processing automobile structural components,using the DYNAFORM software to simulate and analyze the molding process, accurate prediction the forming process ,Thickness variation, strain and metal flow of sheet metal, so as to provide the best plan for die design.using the SolidWorks software to design the punch and die, positioning device,discharge device and fixed structure, completed the design of the die structure.according to automobile structure shape,size, precision, process requirements and The design parameters from DYNAFORM software for sheet metal analysis, in accordance with the relevant design process, finish all the design of the car parts stamping die. Finally draw overall plans and some of the engineering drawings.

Keywords Structural parts Stamping die design Sheet metal parts solidworks dynaform
