Based on the rigid-plastic deformation finite element method and the heat transfer theories, the forming process of cross wedge rolling was simulated with the finite element software DEFORM-3D. The temperature field of the rolled piece during the forming process was analyzed. The results show that the temperature gradient in the outer of the work-piece is sometimes very large and temperature near the contact deformation zone is the lowest while temperature near the center of the rolled-piece keeps relatively stable and even rises slightly. Research results provide a basis for further study on metal flow and accurate shaping of work-piece during cross wedge rolling.

Cylindrical Workpiece

The vacuum hot bulge forming has been used in aerospace industry to manufacture cylindrical workpiece with improved mechanical properties and reduced fabrication cost. Vacuum hot bulge forming is based on the material soften and the stress relaxation theory. Different from other metal forming techniques, deformation of the workpiece takes place well below yield point and the amount of plastic deformation is directly relaxed to heating temperature and holding time. In this paper, a two-dimension thermo-mechanical coupled finite element model was developed. In this model, nonlinear radiation heat transfer and thermal physical properties of material depending on temperature were considered. This paper carried out numerical simulation of vacuum hot bulge forming of BT20 Ti-alloy cylindrical workpiece by using finite element software MSC.Marc. The temperature field, deformation field and stress field of hot bulge forming of BT20 Ti-alloy cylindrical workpiece were calculated. Numerical simulation results were accorded with experimental ones, which provided for the practice production as theory bases.

Continuous extrusion is an advanced process for manufacturing copper strip. Its successfully industrial application is to manufacture copper strip. Based on finite element method (FEM), using the Deform-3D software, this paper simulates continuous extrusion forming process for copper strip, and analyzes the effect of different feedstock diameter on metal flowing temperature, effective stress, velocity, rotating torque. The results show that: feedstock diameter greatly affects the continuous extrusion forming process; Under the same rotating speed, as feedstock diameter increases, the metal flowing velocity increases. It is benefit to enhance the productivity; As feedstock diameter increases, the temperature of the billet and tooling increases, and the torque of extrusion wheel increases, which leads to tooling wear seriously.
