前言矫直工序几乎是金属加工制品必经的一道工序,而矫直工序的作用对成品质量平直度和平面度有很大的影响。但是对于反复弯曲矫直的基本原理的研究,迄今才进行到一定程度,而对矫直过程中变形原理的综合研究还几乎没有。通常,对棒材、板材的纵向曲率进行矫平时,因为矫平后的平直度和平面度决定于矫直机出口材料的曲率及矫平直后的回弹量,所以研究矫直后的平直度和平面度时,在解析中不仅必须考虑材料通过矫直机时的变形过程,而且必须考虑在此期间的加工滞后现象。本文为了阐明棒材或板材的反复弯曲矫直的变形原理,提出了求二维反复矫直后材
Foreword Straightening process is almost a metal processing products must pass a process, and the role of straightening process on the finished product quality flatness and flatness have a great impact. However, the research on the basic principle of repeated bending and straightening has been carried out to some extent so far, and there is almost no comprehensive study on the deformation principle in the straightening process. Normally, when leveling the longitudinal curvature of bars and plates, the flatness and flatness after leveling depend on the curvature of the material at the exit of the leveler and the amount of rebound after straightening. Therefore, Flatness and flatness, the deformation process must not only be considered in the analysis of material through the straightening machine, but also must consider the processing lag during this period. In this paper, in order to clarify the deformation of bar or plate bending and straightening repeatedly proposed two-dimensional repeated straightening after the material
