Abstract：

The tube forging is the important part of mechanical equipment,such as petroleum and drilling industries,so it is requested to have the high intensity,high anti-pull and anti-fatigue properties.During the upset forging of tube parts,it is easy to occur the instability and enfold.At the same time,the forging blank volume is hard to control,which makes the forming difficult and forging quality hard to control.In this paper,the upset forging tube part's forming process is simulated and analyzed by the Deform-3D software,meanwhile,the defects are predicted.Based on the simulating results,the original forming progress and the die structure are improved and optimized.The simulation results using the Deform-3D software have a good agreement with the experimental results.So the simulation results and its processing parameters have a good guide for designing the head upsetting die of the drill pipe.
