摘　　要：文章从拉伸机改造前液压系统的现状出发,针对液压系统存在的问题和用户对液压系统改造的要求,对液压系统进行了优化设计,液压系统的优化设计从主泵控制方式的选择、主拉伸缸控制方式的选择及固定夹头同步控制设计三个方面进行详细阐述。改造后设备及液压系统的主要技术参数、控制系统的功能、生产的产品厚度、机列速度等技术参数均达到合同及设计的要求,机组运行正常。Based on the current situation of the hydraulic system before the transformation of the stretching machine,the paper optimizes the hydraulic system in view of the existing problems of the hydraulic system and the user’s requirements for the transformation of the hydraulic system.The optimization design of the hydraulic system is elaborated from three aspects:the selection of the control mode of the main pump,the selection of the control mode of the main drawing cylinder and the sunchronous control design of the fixed chuck.After the transformation,the main technical parameters of the equipment and hydraulic system,the function of the control system,the thickness of the product produced,the train speed and other technical parameters meet the requirements of the contract and design,and the unit runs normally.
