摘要：

针对多楔带轮旋压增厚成形过程中零件上端结构的内侧过渡区材料折叠，基于Simufact平台建立了多楔带轮旋压增厚三维有限元模型，并采用有限元模拟分析变形区材料塑性流动规律和折叠缺陷产生机理，提出使变形区材料在上端局部增厚、下端有效过渡的旋轮结构设计方法。模拟结果表明：应用该方法可有效约束材料流动，使得外壁成形质量得到显著提高，且旋平后圆角处折叠得到消除。根据模拟获得的最优工艺参数组合进行了生产试制，成形后试制件过渡区未出现折叠裂纹，且外壁增厚到3.5 mm，上下凸筋成形较好，因此有限元模拟分析和模具优化思路是可行的。

In order to avoid material folding in the inner transition region of upper structure for multi-wedge pulley during the spinning thickening forming process, a three-dimensional finite element model of multi-wedge pulley spinning thickening was established based on Simufact platform, and the plastic flow law of material in the deformation region and the mechanism of folding defects were analyzed by finite element simulation. Then, a design method of rotating wheel structure was put forward, which made the material in the deformation region thicken locally at the upper end and transfer effectively at the lower end. The simulation results show that the method can effectively restrain the material flow, greatly improve the forming quality of outer wall, and eliminate the folding at rounded corners after spinning flattening. According to the optimal combination of process parameters obtained by the simulation, the trial production is conducted without folding crack in the transition region, and the outer wall is thickened to 3.5 mm, and the upper and lower ribs are well formed. Thus, the finite element simulation analysis and mold optimization ideas are feasible.
