|
分析了台阶成形过程中模具及金属变形的特点。发现产生螺旋状台阶的原因及其存在区间。从理论上阐明了设计楔横轧模具过渡段应遵循的准则。对比分析了多种满足过渡段设计准则的方案，指出最佳过渡方案为截止轧齐法，并给出了求解轧齐曲线方程的三种体积平衡原理及相应公式。最后应用微体积平衡原理求解了斜台阶轧齐曲线方程。

The characteristics of the die appearance and metal deformation in the process of step shaping were analyzed in this paper. The cause of producing the spiral step and its region was discovered. The criterion that should be obeyed as designing the die transition of cross wedge rolling was expounded in theory. Contrasting and analyzing many schemes that are satisfied with the transition criterion, the way of cut-off step shaping was pointed out as optimum. Three principles of volume balance and its relevant formula were presented to solve the formula of step shaping curve. In the end, the shaping curve of oblique step was done with the principle of micro volume balance.
