Impact of process parameters on the auto claw-pole thixoforming process

Thixoforming of steel is a potential forming technology, which can realize near-net-shape forming process with good quality in one forming step. in this paper, thixoforming process was used to replace the conventional hot forging process to form the auto claw-pole. The finite element code Forge2008© was used to simulate the auto claw-pole thixoforming process. The impact of three main process parameters such as initial billet temperature, punch speed and die temperature on the forming process were investigated. The reasonable process parameters for the auto claw-pole thixoforming were obtained: initial billet temperature 1430∼1440°C, punch speed 100∼200mm/s and die temperature 300∼400°C. © (2011) Trans Tech Publications.
