根据作者的实践,木文从冷挤模架、凸模、凹模三方面对模具结构合理性进行分析,并着重于介绍与现有资料所推荐的模具的不同处。 一、冷挤模架 在冷挤加工中,凸模和凹模的安装方法对工具寿命和冷挤件精度的稳定有很大影响。冷挤模架的设计应该确保凸模和凹模的安装精度以及保证挤压精度不受压力机框架的变形影响。并谋求凸、凹模小型化以降低
According to the author’s practice, from the cold extrusion die frame, punch, die three aspects of mold structure rationality analysis, and focuses on introducing and existing information recommended by the mold at different points. First, the cold extrusion die in cold extrusion process, the installation of punch and die on the tool life and cold extrusion precision has a significant impact on the stability. The design of cold extrusion mold frame should ensure the accuracy of the installation of the punch and the die and the extrusion accuracy is not affected by the deformation of the press frame. And to seek convex, die miniaturization to reduce
