铝合金接触网零件锻造自动化工艺关键点分析

Analysis of Key Points of Automatic Process for Forging of Aluminum Alloy Fittings of OCS

铝合金以其质量轻、强度高、耐腐蚀性好等特点,成为高速铁路接触网腕臂定位的首选材料。随着简统化新型腕臂定位装置的推广应用,锻造铝合金连接件在高铁领域应用逐渐增多,由于铝合金锻造的工艺特殊性,在零件锻造过程中靠人工很难保证产品质量,必须使用自动化的生产线。本文根据具体工艺要求,针对铝合金锻造自动生产线自动化设计,分析了整个生产线的工艺流程,从可行性分析、产品优化设计、自动化工艺设计、自动喷雾润滑系统等关键项点进行了研究,为接触网铝合金零件锻造自动化工艺的实现提供了支撑。

The aluminum alloy, featured with characteristics of lightweight, high strength, corrosion resistant, is becoming the preferred material for OCS registration devices of high speed railway. Along with the development and application of registration devices on a new type of cantilevers which are more simplified and unified, the forged aluminum alloy connection fittings being applied in high speed railways are becoming more popular;the fittings must be forged by means of the automatic production line since the special characteristics of the process for forging the fittings, quality of which is difficult to be guaranteed by manual forging. The paper, in accordance with the actual requirements of the process and with regard to the design of automatic production line for forging, analyzes the technological process of the whole production line, studies the key points of feasibility analysis, production optimized design, automatic process design, automatic spraying lubrication system, providing support for realizing of automatic process for forging of aluminum alloy fittings of OCS.
