摘要
Flat metal strips are deformed progressively into profiles with certain geometry sections by a series of successive rotating rolls at the room temperature, and it is called the cold roll-forming. An effective method is given for roll design to avoid major defects via finite element method （FEM） simulation using a booting model. The simulation gives reasonable fit to the actual product in the two major roll-forming defects, i.e. , edge wave and springback. The redesigned rolls using the approach of multi-stand FEM simulation can effectively control these two defects.
辊弯成形工艺是一种在常温下将平板金属材料通过连续转动的成形辊成形为所需截面的加工方法。本文通过有限元模型建立了一套避免重大产品质量缺陷的设计方法。通过对真实产品的仿真,在设计中考虑了两个辊弯成形主要缺陷,即边波和回弹。设计结果表明,该设计方法能够有效地控制这两大质量问题。
