[0036] How it works

[0037] When the U-shaped aluminum groove bending machine starts to start from a static state, the raw material plate 13 is disposed at the loading plate 14 from the conveyor belt 22 via the unloading plate 24. The raw material plate 13 is pressed down by gravity, and the loading plate 14 drives the sensing slide bar 16 to move in the direction of the loading spring 15. The sensing slide bar 16 pushes the sensing slider 56 to move in the direction away from the ejecting rod 18. The sensing slider 56 is separated from the ejecting rod 18, and the ejecting rod 18 drives the ejecting head 17 to move in the direction of the raw material plate 13 and lifts the raw material plate 13 to the suction cup 36. The suction cup 36 is lifted and drives the suction cup slide bar 38 to move. The suction cup slide bar 38 squeezes the hydraulic fluid and pushes the ejector piston 55 to move. The ejector piston 55 drives the ejector 54 to move in the direction away from the rotating motor 26. The ejector 54 pushes the baffle bar 51 to drive the grinding slide 44 to move, and the grinding head 40 moves to the edge of the raw material plate 13. When the pull rod 45 is close to one end of the pull rod spring 46 and contacts the bracket rod 25, the pull rod 45 and the grinding slide 44 slide relative to each other, the pull rod 45 pushes the blocking rod slider 53 to drive the blocking rod 51 to move in the direction of the blocking rod spring 52, the blocking rod 51 is out of contact with the top rod 54, and the grinding slide 44 moves in the direction of the rotating motor 26 under the action of the slide spring 47, and the grinding head 40 contacts and closely adheres to the edge of the raw material plate 13. At this time, the grinding motor 48 starts to deburr the edge of the raw material plate 13, and the rotating motor 26 starts to make the rotating frame 29 rotate around, so that the grinding head 40 grinds the raw material plate 13 around to prevent the raw material plate 13 from having burrs on the edge of the raw material plate 13. The unevenness leads to stress concentration, which may break when bending.

[0038] When the raw material plate 13 is polished all around, the main hydraulic cylinder 11 starts to drive the support rod 25 to move toward the ejector rod 18, and the suction cup 36 drives the raw material plate 13 to push the ejector rod 18 to its original position. The lower bending hydraulic cylinder 21 starts to drive the lower bending rod 19 to move toward the raw material plate 13, and the lower bending rod 19 contacts the raw material plate 13. At the same time, the upper bending motor 30 starts to drive the bending gear 32 to rotate through the bending pinion 33, and the bending gear 32 drives the bending head 34 to move and contact the raw material plate 13 through the bending screw 31. The bending head 34 moves relative to the lower bending rod 19 to bend the raw material plate 13, and the main hydraulic cylinder 11 resets and moves, and the air pump 37 moves to blow air into the suction cup 36, and the suction cup 36 is separated from the raw material plate 13, and the bending is completed. After the bent raw material plate 13 is taken away, the main hydraulic cylinder 11 moves toward the ejector rod 18 again, and the suction cup 36 contacts and pushes the ejector head 17 to move toward the ejector rod 18. The suction cup 36 passes through the middle through hole of the carrier plate 14 to push the ejector rod 18 to its original position and fix it.
