Forging Process Development of Thrust Cone Based on Simulation Technology

以推力锥锻造成形工艺开发为目的,分析了推力锥产品锻造工艺的可行性,提出了2种锻造工艺方案,利用金属塑性成形仿真软件DEFORM-3D,对2种工艺的推力锥锻造成形过程进行了仿真.通过工艺优化,提出了精备料、准定位、快成形的推力锥锻造成形新工艺,即锯切下料、空气锤上镦粗及预锻、摩擦压力上机终锻的推力锥锻造工艺.通过生产试制及产品检测,获得了壁厚差在1.5 mm以内、摩擦面的平面度低于0.7 mm、无需后续机械加工的推力锥锻件.

In order to develop forging process of thrust cone, its feasibility is analyzed. Two forging process schemes are proposed and simulated by using Metal plastic forming software DEFORM-3D. A forging process of accurate stock preparation, precise fix position and quick formation is made after optimized. The process is that saw cutting, upset and preforge on pneumatic hammer, finish-forge on friction press. Trial-manufacture indicates： forging p feasible ; wall thickness difference value of the forging piece is less than 1.5 mm; its plateness of than 0.7 mm ; the further machining operation is not needed.
