铜阴极板辊式矫直机参数研究

矫直是一个复杂的过程,包括几何非线性、材料非线性、接触非线性等问题,其数值模拟涉及到多个学科。以铜电解阴极板加工机组中的矫直机为研究对象,采用有限元软件ANSYS建立了矫直辊和阴极板的仿真模型,利用计算机模拟了铜阴极板的矫直过程,最终以矫直后的残留率和最大残余应力作为评价指标,利用正交因素法比较分析不同矫直参数对矫直效果的影响,获得最佳的矫直参数组合,对企业矫直机的设计开发提供参考,具有一定的实用价值及生产指导意义。

Parameter Research on Copper Cathode Board Roller Type Straightening Machine

Straightening is a complex process, which includg geometric nonlinear, material nonlinear, contact nonlinear and so on, therefore, the numerical simulation of the straightening is concerned with many subjects. The main study object of this paper was roller type straightening machine as a part of the production line to process copper electrolysis cathode. The simulation models of straightening roller and copper cathode board had been established by finite element software AN SYS, and the straightening process of copper cathode board was imitated by computers. Taking bending curvature residual rate and the biggest residual stress as appraisement criterion when the straightening have been completed, orthogonal factor law was adopted to study the influence of different straightening parameter for straightening effects, getting the best straightening parameter combination, which can provide reference for the design and development of the straightening machine for enterprises, and have certain practical value and production guidance meaning.
