摘要
本文研究了相对弯曲半径、型材内缘宽度等绕弯件几何参数对LY12M帽形型材张力绕弯过程中的断面形状精度的影响,提出了改进绕弯件断面形状精度的措施,为实际生产提供了指导。
In this paper,the effect of relative bending radius and the width of the inner fringe on the section precision of LY12M hat-section profile in rotary draw bending process with stretching force is studied The measure of improving the section precision of parts is proposed
