Development And Prospect Of Cold-drawing Machine
- Feb 15, 2017 -

With in the 1990 of the 20th century, China began research, and application cold pulled pipe technology yilai, cold pulled pipe technology to widely reference Yu monomer hydraulic cylinder tube and the engineering mechanical oil cylinder of manufacturing, cold pulled machine as cold pulled pipe of main processing equipment, it is for at room temperature Xia pulled business black and the nonferrous metals Rod material material and on hot, and extrusion zhihou of shortage tube for two times processing, is production small, precision, thin-walled, make mechanical performance pipe of main processing equipment. 1 cold drawing machine type: cold drawn according to the bed structure, can be roughly divided into three separate, both frameworks. According to the driving pattern, can be divided into chains, hydraulic, rack, screw type, such as various types of drawing machine. Before the 80 's of last century, China's steel tube cold-drawing machine for single-chain, double chain drive type drawbench and fixed bed type hydraulic cold-drawing machines, straightening machines.
