河北省昌黎县标准件厂在生产光螺母中,原采用压球、压六角、冲孔三道工序,后改为成形、冲孔两道工序,并在单机自动的基础上实现了双工位自动生产。该双工位自动装置如图示,其工作原理是:料豆(毛坯)从料斗口顺弹簧管进入嘴架14,当滑板10下行时,滚轮11压迫斜铁13,使滑块17向右运动,驱使成形钳16摆到成形模位置,冲孔钳20摆到冲孔位置。这时成形冲头、
Changli County, Hebei Province, the standard parts factory in the production of light nuts, the original pressure ball, pressure hexagonal, punching three processes, later changed to forming, punching two processes, and stand-alone automatically on the basis of a duplex Automatic production. The duplex automatic device is as shown in the figure, and its working principle is as follows: the bean (raw material) enters the mouth frame 14 through the spring tube through the mouth of the hopper; when the slide plate 10 descends, the roller 11 presses the wedging iron 13 to make the slider 17 to the right The forming forceps 16 is driven to move to the forming die position, and the punching forceps 20 is put into the punching position. At this time forming punch,
