摘　　要：针对一汽主机厂汽车内板件模具在调试过程中存在的调试效率低、工艺寻优困难、过度依赖人员经验等问题,结合汽车内板件的成形特点,运用Dynaform软件和Box-Behnken设计模拟不同工艺参数下板料的成形过程,采用响应面法建立压边力、拉延筋阻力系数、摩擦因数与产品减薄率之间的二次拟合模型,从而获得合理的工艺参数,完成二元工艺过程图的绘制。结合模型开展全面试验法,以三角形为边界区域完成三元工艺过程图的绘制。试验结果表明,利用响应面法建立的工艺过程图能够真实地反映板料冲压成形过程中产品的减薄率情况,并对模具调试人员在实际生产中有着很强的指导作用。In view of the problems of low debugging efficiency,difficulty in process optimization and over-reliance on personnel experience in the debugging process of automobile inner panels die in FAW main engine factory,combined with the forming characteristics of automobile inner panels,the forming process of sheet metal under different process parameters was simulated by Dynaform software and Box-Behnken design,and the response surface method was used to establish the quadratic fitting model between blank holder force,resistance coefficient of drawing rib,friction factor and thinning rate of product so as to obtain reasonable process parameters and complete the binary process drawing.Then,the ternary process drawing was completed by a comprehensive test method combined with the model taking the triangle as the boundary region.Test results demonstrate that the process drawing established by the response surface method can accurately reflect the thinning rate of product in the stamping process of sheet metal,and provide valuable guidance to die debugging staff in the actual production.
