苏联难熔金属及硬质合金研究所申请的一项专利中,推荐采用链式连续项推拉拔机生产管材、线材及棒材。从结构图中可以看出,这一个拉拔装置2及六个拉模3等组成。当链条10运动时,工件14进入顶推装置1的槽形件13内。支承辊18沿曲线滚道17滚动时,链条10与支座15发生作用,将工件14推入拉模3。拉模3是借电磁铁5及杠杆4动作的。在工件14的种设备是用顶推与拉拔相结合的方法生产各种型材的。链式连续顶推拉拔机由一个顶推装置1、
In a patent application filed by the Institute for Refractory Metals and Cemented Carbides in the United States, it is recommended to use chain-type continuous push-pull machines to produce pipes, wires and rods. It can be seen from the structure diagram that the drawing device 2 and the six pulling dies 3 are composed. When the chain 10 moves, the workpiece 14 enters the trough 13 of the jacking device 1. When the backup roller 18 rolls along the curved raceway 17, the chain 10 acts on the support 15 to push the workpiece 14 into the die 3. The drawing die 3 is operated by the electromagnet 5 and the lever 4. In the workpiece 14 kinds of equipment is the combination of push and pull the production of various profiles. Chain continuous push pull machine by a push device 1,
