【摘要】 在明确辊式冲压工作原理的基础上,结合辊式冲孔机的结构分析,针对在冲孔形状上出现的误差,提出了凸模的优化模型。同时,针对由齿轮间隙引起的两冲辊之间(即凸、凹模之间)相位角的变化,提出设计角度调整机构的理念。更多还原

【Abstract】 Based on the operational principle and the structural analysis of rolling punch,this paper demonstrates the optimal design of convex-mold,which can solve the error problems of bore-shape.Meanwhile,it puts forward the conception of angle adjusting mechanism from the fact that the wheel clearance could lead the changes of phase-angle between two roller.更多还原
