[0028] How it works

[0029] Place the two ends of the sheet metal flat on the toothed anti-skid bottom pads 22 on the two sets of movable seats 18. After adjusting the fixed position, start the micro cylinder 26, control the piston rod of the micro cylinder 26 to push out and drive the toothed anti-skid clamping plate 27 to descend, until the toothed anti-skid clamping plate 27 contacts the surface of the sheet metal, and then clamp the sheet metal on the toothed anti-skid bottom pads 22 to complete the rapid fixation of the sheet metal. When the bending position of the sheet metal needs to be automatically adjusted, control the direction of rotation of the output shaft of the driving motor 6 and drive the threaded screw 7 to rotate inside the mounting seat 3 through the mounting bearing 8. The movable nut seat 9 is driven by the engagement of the rotation of the threaded screw 7 and at the same time moves on the positioning slide Under the limiting action of the sliding of the block 10 and the guide slide rail 5, the movable nut seat 9 can make linear motion on the threaded screw 7, thereby driving the automatic clamping and placing seat device 14 on the connecting arm 12 to move horizontally, thereby adjusting the position between the sheet metal and the bending pressure block 30, and realizing automatic adjustment of the bending position. Finally, the piston rod of the hydraulic cylinder 29 is controlled to be pushed out to drive the bending pressure block 30 to descend. When the bending pressure block 30 descends and contacts the surface of the sheet metal, the sheet metal is automatically bent. Under the impact force of the descending bending pressure block 30, the sheet metal can drive the two sets of movable seats 18 to slide on the damping guide rail 17 through the telescopic spring 20 and the damping sleeve 19.
