基于仿真技术的推力锥锻造工艺开发

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1.5mm以内、摩擦面的平面度低于0.7mm、无需后续机械加工的推力锥锻件.

Forging Process Development of Thrust Cone Based on Simulation Technology

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 pre-forge on pneumatic hammer,finish-forge on friction press.Trial-manufacture indicates: forging process of thrust cone is feasible;wall thickness difference value of the forging piece is less than 1.5 mm;its plateness of friction surfaces is less than 0.7 mm;the further machining operation is not needed.
