模拟分析了原工艺流程中弹簧座的拉深成形状况,模拟结果与其在局部位置的减薄和增厚难以满足生产要求的现状高度吻合。针对产品的质量状况,以工件凸台部位对应的凸模圆角半径和模具间隙作为影响因素,建立了工件最大减薄率和最大增厚率回归模型。在回归模型的基础上进了多目标优化,优化得出的参数为产品的质量提供了保障。
Simulation analysis of the original process of spring seat deep drawing forming conditions, the simulation results and its location in the local thinning and thickening difficult to meet the production requirements of the status quo is highly consistent. According to the quality condition of the product, the regression model of the maximum reduction rate and the maximum increase rate of the workpiece was established by taking the radius of the punch radius and the mold clearance corresponding to the boss part of the workpiece as influential factors. Based on the regression model, a multi-objective optimization is carried out. The optimized parameters provide the guarantee for the quality of the product.
