摘要
目的研究汽车曲轴盖板复合加工工艺的可行性。方法根据零件特点,采用多道次拉深和整形相结合的加工工艺成形零件,并利用有限元技术,对成形过程进行了数值模拟分析,然后结合物理实验对工艺可行性进行了验证。结果试制出的零件表面质量较好,法兰内缘处梯形凸台尺寸精度达到了要求,和有限元仿真模拟结果相吻合。结论采用多道次拉深和整形复合工艺所获得的汽车曲轴盖板,完全满足零件实际使用要求,成形工艺有效、可行。
The aim of this study was to investigate the feasibility study of the cover of automobile crankshaft machining process. According to the characteristics of the part,parts were assembled by machining process combined with multi pass drawing with shaping,and the numerical simulation of forming process was analyzed by the finite element technology. Finally,the feasibility of process was verified using physical experiments. The surface quality of the trial is good,the size precision of the trapezoidal bulge at the inner edge of the flange meet the requirements,which was consistent with the finite element simulation results. The automobile crankshaft cover board processed by multi-pass drawing and plastic composite technology can fully meet the requirements of the actual use,and the forming process is effective and feasible.
