一、原理: 冲孔压弯自动装置采用了简单的射流技术,用射流元件控制气缸完成它的送料动作。把这套装置安装在模具上,把料自下而上放在料斗里,放满为止,打开气源,当冲床滑动块上升碰上限气行程开关,双稳元件进行切换,控制双相放大器,使气缸活塞向前运动,带动推料块,把料推到模具里,冲压滑块下降碰下限行程开关,双稳元件再一次进行切换控 First, the principle: Piercing bending automatic device uses a simple jet technology, with jet components to control the cylinder to complete its feeding action. The device is installed on the mold, put the material from bottom to top on the hopper, fill it up, open the gas source, when the press slide up limit run limit switch, bistable components to switch, control of dual-phase amplifier, So that the piston forward movement of the cylinder, driven pusher block, the material pushed into the mold, press the slider down to touch the limit switch, bistable components once again switch
