单轴变截面冷弯成型系统设计

摘要

Roll fanning is a high-efficiency,energy-saving and material-saving forming technique for the plate metal.Based on stating the characteristics of roll forming, a new roll forming technology-flexible roll forming, which concept and composition are introduce d.Then the mechanical structure of the single-axis flexible roll forming machine designed by North China University of technology is expounded,and the basic control strategy for variable cross-section forming as well.Moreover,the control system structure and control principle of the forming roll are analyzed and the software environment of the control system is summerized in this paper.By forming experiment, the precision of track control and effect factors are analyzed which provides useful experience for further developing variable cross-section roll forming production line.%冷弯成型是一种高效、节能、节材的板金属成型工艺.在阐述冷弯成型基本特点的基础上,介绍了一种新型冷弯成型技术一柔性冷弯成型的概念与系统构成.详细介绍了北方某大学研发的单轴变截面冷弯成型机的机械结构,阐述了实现板材变截面成型的基本控制策略,分析了变截面轧辊的控制系统结构与控制原理,简述了控制系统的软件平台.通过轧制实验,分析了变截面板材轨迹控制精度及各种影响因素,为今后进一步开发变截面生产线提供了有益的经验.
