【摘要】 介绍了冲压板材的成形性直接影响到冲压件的质量，板材性能的评价指标也应随着对冲压件的质量要求的提高进行更新和进步。为了与要求冲压件不破裂、形状精度高和尺寸精度高相适应，从抗破裂性能、抗起皱性能和抗弹复性能三方面衡量板材的冲压性能，比只考虑抗破裂性能更合理、更科学、更具有实用性。更多还原

【Abstract】 To describe that forming property of stamping sheet metal can directly effect quality of stampings. Estimating target to property of sheet metal should be replaced and improved by new ones with improvement of stampings quality required. In order to suit the requirements such as unbroken, high shape precision and high dimensional accuracy of stampings, stamping property of sheetmetal should be measured from three aspects of antibroken, anticrisp and antispring-go. It is more rational, scientific and practical than only consider from aspect of antibroken.更多还原
