摘　　要：重型机械中的轴类零件在高温锻造后需要进行矫直处理,以满足实际使用要求。综合现有的机械矫直和检测方法,设计大型轴类零件矫直设备的主机和液压控制系统。介绍矫直设备的结构及工作原理、矫直机的数控系统和控制方案;提出矫直、检测、清理氧化层的液压控制方案,并且对检测系统的稳定性进行理论分析和AMESim仿真,最后分析了矫直机的伺服系统,它提高了矫直机的精度。该矫直机设计有氧化皮清理机构,提高了矫直和检测的精度,减小了误差,检测矫直处于同一工位并形成反馈系统,提高了生产效率,为大型轴类零件的矫直提供了一种实用高效的新方法。In order to meet practice requirements,the heavy shaft should be straightened after forging.Based on existing mechanical straightening and testing methods,a hydraulic system for straightening equipment was designed.The structure and working principle of the straightening equipment were introduced.The numerical control system and control scheme of the straightening machine were raised.Then the hydraulic control scheme of straightening,probe,and oxide cleaning was put forward.In order to demonstrate the stability of the probe hydraulic system,the mathematics analysis and AMESim simulation of the system were carried out.Finally,the servo system that improved the stability of the straightener was discussed.The designed straightening machine with the oxide cleaning mechanism has high accuracy of straightening and testing;the production efficiency is improved because probe and straightening are at the same station with the feedback system.It provides a practical and efficient method for heavy shaft straightening.
