本文提出了求不规则压延件展开毛料的热传导模拟法,通过计算机数值求解,得到了任意形状不规则压延件的毛料外形。由典型零件的压延实验和实际生产零件毛料的对比分析证明,热传导模拟法是合理的,可行的。本文还提出了确定多次不规则压延件过渡形状的合理方法。

A heat couduction analogue method is put forward for determing the blank contour of irregular cups. A program FEMBLC based on the finite element method has been elaborated for this purpose without preassigning an arbitrary chosen point on the contour curve, the computer will perform the calculation automatically until a preassigned precentage of precision has been attaind. Furthermore, it is shown that the geometry of the transient part shapes in multi-stage drawing are all isothermals and can be egually drawn using the FEMBLC. The blank contours drawn this way show good conformity with the experiment.
