基于行程控制的校直工艺理论研究

STUDY ON THE STRAIGHTENING TECHNICAL THEORY BASED ON THE STROKE CONTROLLED

已有的校直工艺数学模型为压力控制型，在实际生产中难以实现，故需研究行程控制型校直工艺数学模型。通过研究弹区比在精密校直过程中的影响，建立了弹区比、力参量和应变比的方程，进而提出一种校直行程计算方法。实验表明，该方法对轴类零件的校直参数计算是有效的，对精密校直机的设计和制造有一定的指导意义。

In this paper,the effect of the elastic region ratio on precise straightening has been studied.From this ,we built up an equation of elastic region ratio,power and strain,and put up a new method of precise straightening based on the stroke controlled, which will be a great help to design and manufacture of automatic precise straightening press.
