摘　　要：采用车削加工生产的轴瓦零件,其表面粗糙度较高、耐磨性较低、易发生胶合失效、零件寿命较短。改用冷挤压精密整形工艺可以降低轴瓦表面粗糙度,提高轴瓦的成形质量。本文通过Q-Form-3D模拟分析和试验相结合,对轴瓦精密整形进行了工艺分析和设计,得出了工艺参数,并依据分析结果设计了合理的模具,为轴瓦的生产提供了理论依据。By turning processing production of bearing parts,the surface has high roughness,low wear resistance,is liable to agglutination failure,resulting in short life parts. The use of cold extrusion for precision plastic technology can reduce the surface roughness of bearing,and improve the quality of the bearing shell forming.Through Q-Form-3D simulation and experiment,the combination of process analysis and design of bearing precision plastic,the process parameters were obtained,and according to the results of analysis,the reasonable mold was designed,for the bearing shell. It provides a theoretical basis for its production.
