摘要
变值轧制成型是采用轧制的方式制造零件或毛坯的工艺方法 ,是一种新兴的有发展前途的制造技术。介绍了变值轧制成型工艺的基本原理和工艺方法 ,变值轧制成型时 ,辊缝跟踪设定的数值 ,辊缝是工件长度的函数 ,同时分析了设定辊缝、轧制压力、轧机刚度等因素对被成型工件厚度精度的影响。以变截面板弹簧形成理论和制造过程为例 ,介绍了变值轧制成型技术在农业机械和农用运输车变截面板簧制造方面的应用。变值轧制成型技术将成为制造具有变截面形状结构零件的主要方法。
The variable data rolling forming that is variable cross-section rolling forming, is a new technological method which has a bright future in the building technique, using the rolling method to produce work-pieces or semi-finished products. Basic principle of the variable data rolling forming technology is introduced in this paper. When variable cross-section rolling, roll gap opening changes with the preset data which is the function of the length of work-piece. The influence on precision of work-piece thickness by preset gap and rolling force as well as mill rigidity, is analyzed. The application of the variable data rolling is introduced by example of the forming theory and manufacturing process of taper leaf spring of farming machinery and vehicle and truck. The variable data rolling forming will become the major methods to produce work-piece which has variable section structure.
