| 摘 要： | 目前快速深拉伸液压机大多采用液压开关式控制系统,它存在着响应速度低、冲击振动大及拉伸件废品率高等问题。文章在比较了3种液压控制技术性能及特点的基础上,设计了一种快速深拉伸液压机的电液比例控制系统,使压边力的变化符合了拉伸工艺要求,滑块速度转变平稳,较好地解决了上述问题。

| Abstract: | In most of high-speed hydraulic deep drawing presses,the switch-type hydraulic control system is adopted,and there exist some problems such as the low speed of response,large impact vibration,and the high rate of waste product.Based on the comparative analysis of three kinds of hydraulic control systems,an electro-hydraulic proportional control system is designed for this kind of press.This control system makes the change of blank-holding pressure fit the requirement of the drawing craft,and it also makes the conversion of the slide's speed smooth and steady. |
