板材在成型加工中,其深冲值和压力强度是选择设备、制定工艺的重要依据。当深冲时,随着深冲量的增加,板材的厚度逐渐减薄,冷作硬化,并引起强度和塑性的剧烈变化,很难用确切的公式表达。为了解决这个难题,研究人员采用模拟测试,分别测出几种常用板材在不同深度与面 Plate forming process, the deep-value and pressure intensity is the choice of equipment, an important basis for the development process. When the deep drawing, with the increase of the amount of deep impulse, the thickness of the sheet gradually thinning, cold hardening, and lead to dramatic changes in strength and plasticity, it is difficult to use the exact formula to express. In order to solve this problem, the researchers used simulation tests, were measured several commonly used plates at different depths and surfaces
