Research and Application of Warm Extrusion Forming Technology for Internal Combustion Engine Piston Head

Abstract:

In order to improve the performance of the piston head on the existing conditions, and the warm extrusion forming technology was put forward based on the internal combustion engine piston head traditional production process. The warm extrusion process scheme and finite element boundary conditions was designed reasonable based on research the piston head forming process, the thermal-mechanical coupling model was established. The numerical simulation of the warm extrusion forming was carried out on the DEFORM software platform. The distributions of warm extrusion forming process strain field, stress field and temperature field were forecasted through the theoretical calculation and simulation. And the production equipment tonnage and die structure form were determined preliminarily. The possible problems of forming process were discussed, and the countermeasures were also put forward, provide the reliable reference for internal combustion engine piston head forming process improvement.
