摘要：

以非线性有限元软件Dynaform为平台，对1716印涂铝盖在不同单边间隙下的冲压拉深过程进行数值模拟，分析了首次拉深工序件的最大壁厚、最大壁厚与最小壁厚差值、壁厚减薄率和最小壁厚随模具单边间隙变化的曲线；同时，综合考虑工序的工艺特点、工艺要求、拉深模的磨损规律、模具寿命要求等诸多因素，最终确定拉深模单边间隙的合理范围，并进行了生产验证。结果表明：拉深模单边间隙的合理范围是0.30~0.31 mm；模具单边间隙为0.31 mm时，工序件最小壁厚最大，减薄率最小；考虑磨损规律和模具的寿命要求，实际生产中模具的单边间隙值可取0.30 mm，可成形出合格的工序件。

The drawing processes of 1716 printed and coated aluminium cover under different die unilateral clearances were simulated by the nonlinear finite element analysis software Dynaform, and the curves of the maximum wall thickness, difference values between the maximum and the minimum wall thicknesses, wall thickness reduction ratio and the minimum wall thickness versus die unilateral clearance were analyzed. At the same time, the process characteristics, requirements, wear characteristics of drawing die, die life and so on were comprehensively considered. At last, a reasonable range of the drawing die unilateral clearance was determined and verified by practical production. The results show that the reasonable range of the drawing die unilateral clearance is 0.30-0.31 mm. When the die unilateral clearance is 0.31 mm, the minimum wall thickness is the thickest, while the reduction ratio is the smallest. Considering the wear characteristics and die life requirements, the drawing die unilateral clearance is recommended as 0.3 mm so as to produce a qualified production.
