摘　　要：成型模具是钢管模压校直设备的关键组件之一,实际使用过程中出现变形量较大的问题,对钢管校直的精度产生不利影响。针对使用过程出现的问题,通过Ansys有限元分析软件,建立钢管校直机模具的参数化模型,并对其静态性能进行分析研究。在分析结果的基础上,提出改进和优化的方案,并且对改进后的方案再进行有限元分析验证。结果表明,改进后的模具可以满足使用的要求,最大变形量缩小至原结构变形量的5%。Steel molding mold is the key component of straightening equipment, and which is an important problem of deformation during actual use, and affecting the accuracy of steel pipe straightening seriously. In order to solve the structural problems of the mold, using ANSYS finite element analysis software to build parametric models of steel straightening machine molds, analyzing and studying the static performance of the molds. Based on the analysis results, propose improved and optimized programs, and validated the improved program using finite element analysis. Results showed that the improved mold meet the using requirements well, and the maximum deformation reduced to 5% comparing the deformation of the original structure.
