Computer aided design for cross wedge rolling tools of automobile semi-axes

The multi-wedge cross wedge rolling (MCWR) is a new advanced technology of forming automobile semi-axes with many advantages such as saving the surface of roller remarkably and reducing the size of equipment. The design and calculation of dies is complex, therefore, the technology of MCWR forming automobile semi-axes is limited in practical application to some extent. In order to solve the problems above, the Pro/Engineer was further developed using visualized basic program language, and the complex calculation program for the parameters was worked out including main wedges and side wedges, the movement of the end of rolled part in rolling and shaping curves in each phase on MCWR tools of automobile semi-axes, and then the calculated results were placed in access database and using the software of Pro/Engineer to module for the MCWR tools, which achieve the CAD parametric design for automobile semi-axes and provide an efficient method for the production of automobile semi-axes.
