模具加工工艺与技术是保证模具制造质量的重要手段。本文优化了汽车覆盖件模具制造流程,提出了汽车覆盖件模具拉延、修边、冲孔、翻边、整形等模具流水线制造模式,论述了这种流水线制造模式“一个生产流程”的加工工艺,是汽车覆盖件模具生产企业生产方式的发展方向,对于控制质量、加强模具制造过程中计划的准确性、生产的均衡性、最大地发挥企业现有资源有一定的参考价值。 Mold processing technology and technology is to ensure the quality of mold manufacturing an important means. This paper optimizes the mold manufacturing process of automobile cover parts and puts forward the production line of mold assembly line such as drawing, trimming, punching, burring and shaping of automobile cover mold, and discusses the manufacturing process of “one production line” , Is the development direction of production methods of automobile panel mold manufacturing enterprises. It has certain reference value for controlling the quality, enhancing the accuracy of the plan during mold manufacturing, the balance of production and maximizing the existing resources of enterprises.
