RX-300热旋压机电气控制系统的研制

Development of the electrical control systems of RX-300 hot spinning machine

ＲＸ－３００热旋压机的电气控制部分分为五个系统：（１）中频感应加热系统；（２）主轴传动系统；（３）辊轮进给系统；（４）液压操作系统；（５）工作参数测量和数字显示系统．它不但解决了传统旋压机存在的对工件加热不均匀，易使工件变形烧损的难题，同时也提高了工作效率和产品质量．该机适合于旋压多种金属管材，生产钨、钼等难熔金属薄壁管材更显示出其优越性．

The electrical control part of RX-300 hot spinning machine consists of five sys- tems: (1) mid-frequency induction heating system; (2) main shaft transmission system ; (3) roll wheel feeding system ; (4) hydraulic operating system ; (5) system for working para- meter measurement and digital display. The use of these systems can not only solve the problems existing in a traditional spinning machine, such as uneven heating to the workpiece and tendency to deform and burn the workpiece, but also raise the work efficiency and assure the quality of products. Equipped with those systems, RX-300 hot spinning machine is suit- able for spinning of metallic tubes, especially thinned-wall tubes of refractory metals such as W and Mo.
