冷弯成型过程中变形过渡区的研究

On the Transition Zone of Deformation in Cold-Bend Forming

采用能量法原理对冷弯变形过程进行研究与分析，建立了变形过渡区长度的理论表达式．通过实测证实了理论值与实测结果吻合良好，对深入探讨冷弯成型过程中的力能参数具有十分重要意义．

The cold-bend forming process was studied using energy method and a theoretical length expression of the transition zone of delormation was thus derived. The values catculated are in conformity tothose measured. It is of significance to further understanding the force-energy parameter in the process ofcold-bend forming.
