The punch load of nickel plated steel strip and steel strip was compared,and the surface morphology of inside wall of circular cups with different stamping depths was analyzed.
在RG2000型微机控制电子万能试验机上对镀镍钢带进行冲压成型试验,研究了镀镍钢带在不同压边力作用下的成型性能,对比了镀镍钢带与未镀镍钢带在冲压成型中所需的冲头载荷,对不同冲压深度杯形件侧壁内表面形貌变化做了比较研究。
Through analysis it is concluded that for a given rock and given tooth profile,the cut-in displacement(depth)is in a linear relationship with cut-in load,the volume of breaking pit decreases with t.
对试验结果进行分析,得到了围压作用下对于所试验的岩石和齿形,压入载荷和压入位移成线性关系;岩石破碎坑的体积随压入载荷的增加而减小;在以相同齿形压入相同岩石的条件下,岩石的破碎面积和体积随围压的增加而减小。
