在冲杯成形过程中,合理的冲头圆角、凹模圆角和模具间隙参数可以提高拉深变形的均匀性,降低易拉罐的生产成本。通过有限元仿真可以得出结论:增加凹模圆角,杯体圆角厚度减小,杯壁厚度增加,所需的成形载荷增加;增加冲头圆角,杯体圆角厚度和杯壁厚度均增加,所需的成形载荷减小;增加模具间隙,杯体圆角厚度和杯壁厚度均减小,所需的成形载荷减小。因此,通过优化凹模圆角、冲头圆角和模具间隙参数,能获得较为理想的杯体性能和较小的能量。

@@@@The pull deep deformation uniformity can be improved and production cost of cans can be reduced if the mould has the reasonable punch fillet、 die fillet and mould gap parameters in the punch forming process .Based on the finite element simulation analysis, some conclusions can be drawn .If the die fillet increases, the thickness of the cup body fillet reduces, the thickness of the cup wall increases , then the forming load will increases.If the punch fillet increases, the fillet thickness of the cup body and the cup wall thickness increase , then the forming load reduces.If the clearance of die increases, the fillet thickness of the cup -body and the cup -wall thickness decrease, then the forming load reduces.Thus the ideal performance of a cup body and a smaller energy can be ob -tained by optimizing the die fillet, the fillet of the punch and die gap parameters .
