One of the valid method to reduce the vertical breaking in deep-drawing of 18-8stainless steel is to adopt a die clearance which is less than the plate thickness.

防止18 - 8型不锈钢技深件纵向开裂的有效措施之一是在拉深时采用小于板料厚度的凸凹模间隙。

By simulating in DYNAFORM, the influences of the factors, such as the friction coefficient, die clearance and material parameter 'sn and r, on stamping formability were studied.

应用dynaform软件进行模拟计算分析，研究了摩擦系数、模具间隙、材料参数(n, r值)等因素对零件成形的影响。

Through choosing the blanking clearance of material in reasonable, just by one die blanking the different thickness of very thin gaskets, the die structure was simple and practical.

通过对材料冲裁间隙的合理选取，只用一副冲模就实现了对厚度不同的超薄垫圈的生产，且模具结构简单、实用。
