摘　　要：常规电镦机各工艺参数多为恒值,在镦粗过程中不能实时控制。本文介绍一种新型电镦机计算机控制系统。在对镦粗速度、加热电流、镦粗压力等主要工艺参数分析的基础上,建立了工艺过程的优化控制系统。优化目标为最佳成形温度,而温度的控制主要通过压力控制来实现。In normal electric upsetting machines,the process parameters were constant and could not be controlled online. In this paper a new computer controlled electric upsetting system is introduced. Based on analysis of main process parameters such as upsetting velocities,heating current,upsetting pressures etc.,the optimum control system of process parameters is determined. The control object is the optimum forming temperature and it is realized by controlling forming pressure.

关 键 词：工艺参数 金属变形 电热镦粗 最优控制
