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。 The roll forming process is a processing method of forming a sheet metal material into a desired cross-section through a continuously rotating forming roll at ambient temperature. This article through the finite element model to establish a set of design methods to avoid major product quality defects. Through the simulation of the real product, the two main defects of roll forming are considered in the design, that is, side wave and rebound. The design results show that the design method can effectively control these two quality problems.
