本文介绍了用于高纯铜、微合金化铜及复杂多元铜合金等高性能铜合金棒材、管材生产和试验的800吨挤压机的工艺设计。根据挤压产品的产品方案进行挤压工艺系统的设计,确定了该挤压机的结构、特点,进行了挤压轴、穿孔针结构设计及强度校核。 This article describes the process design for the 800-ton extruder for the production and testing of high-performance copper alloys such as high-purity copper, microalloyed copper and complex multi-element copper alloys. According to the product scheme of the extrusion products, the design of the extrusion process system was confirmed, the structure and characteristics of the extrusion machine were confirmed, and the design of the extrusion shaft and perforation needle structure and the strength check were carried out.
