为了满足市场对高精度超细管材的需求,以现有的十辊矫直机为基础,通过研究十辊矫直机的矫直原理,设计了一种新型的超细管材矫直机。介绍了超细管材矫直机的主要技术要求、矫直系统的构成,分析了各个主要部件的结构特点及创新。同时,利用有限元软件Abaqus建立了超细管材矫直机的有限元模型,并对超细管材的矫直过程进行了动态仿真研究。根据设计要求,分析了超细管材矫直后的椭圆度、直线度和残余应力,证明了超细管材矫直机设计的合理性。
In order to meet the market demand for high-precision ultra-thin pipe, based on the existing ten-roller straightening machine, a new type of ultra-thin pipe straightening machine is designed by studying the straightening principle of the ten-roller straightening machine. The main technical requirements of the straightener and the straightening system are introduced. The structural features and innovations of each main component are analyzed. At the same time, the finite element model of the ultra-thin tube straightening machine is established by the finite element software Abaqus. The straightening process of the ultra-thin tube is simulated by the dynamic simulation. According to the design requirements, the ellipticity, straightness and residual stress after the straightening of the ultrafine pipe are analyzed, which proves the rationality of the design of the ultrafine pipe straightening machine.
