Feeding gantry and turning system We use the pneumatic feeding flap mechanism and the discharging flap mechanism. The structure and working principle are the same. Only the material flow direction is opposite, so the design principle of the flap is different. There are mainly bracket seat, flap mechanism, connecting rod, tie rod, double-head thread adjusting joint, buffer cylinder, etc. When loading, the piston rod contracts, the blank is lifted, and the blank is immediately rolled to the front end of the turning board and blocked, This position is exactly the center of the conveyor roller), and as the piston rod elongates, the blank will land smoothly on the conveyor roller. Similarly, the turning mechanism is contracted, the piston rod is shrunk, the bad material is lifted off, and the billet is separated from the conveying roller, and the billet is rolled onto the discharging cold bed bench. Its characteristics work smoothly and without impact, thus ensuring the straightness of the workpiece. It is completely different from other turning mechanisms, characterized by large action and large impact force.
