[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] This utility model discloses a bending device for aluminum profile production.
[0025] Reference Figure 1-3 A bending device for aluminum profile production includes a base plate 1 and a bending blade 15. A U-shaped plate 16 is provided on one side of the upper part of the base plate 1. A hydraulic cylinder 11 is rotatably mounted on the lower surface of the U-shaped plate 16. A push plate 14 is fixedly connected to the end of the piston rod of the hydraulic cylinder 11. The bending blade 15 is fixedly mounted on the lower surface of the push plate 14. An avoidance groove is provided on the upper surface of the base plate 1 and below the bending blade 15 to minimize interference between the bending blade 15 and the base plate 1. Fixing pipes 1 are fixedly mounted on both sides of the lower surface of the U-shaped plate 16 and on both sides of the hydraulic cylinder 11. 2. A movable rod 13 is movably sleeved inside the fixed tube 12. The lower end of the movable rod 13 is fixedly connected to the push plate 14, so that the push plate 14 can move stably. Vertical plates 2 are fixedly installed on both sides of the upper surface of the base plate 1. A first transmission mechanism that drives the U-shaped plate 16 to move is set between the upper ends of the two vertical plates 2. A second transmission mechanism that drives the hydraulic cylinder 11 to rotate is set below the first transmission mechanism. L-shaped plates 3 are fixedly installed on the upper surface of the base plate 1 and inside the two vertical plates 2. Clamping mechanisms are set inside the L-shaped plates 3.
[0026] Reference Figure 1-3 The first transmission mechanism includes a lead screw 7 and a motor 9. The lead screw 7 is rotatably mounted between the upper ends of the two vertical plates 2. The upper end of the U-shaped plate 16 is threadedly connected to the lead screw 7. The motor 9 is fixedly mounted on the upper outer wall of one side of the vertical plate 2. The output end of the motor 9 is fixedly connected to one end of the lead screw 7. A horizontal bar 8 is arranged parallel to the lower side of the lead screw 7. Both ends of the horizontal bar 8 are fixedly connected to the corresponding vertical plate 2. Both ends of the U-shaped plate 16 are movably mounted on the horizontal bar 8, so that the U-shaped plate 16 will not rotate with the lead screw 7, that is, it can slide stably.
[0027] Reference Figure 1-3 The second transmission mechanism includes a gear 18 and a rack 10. The lower end of the U-shaped plate 16 has through holes on both sides. The rack 10 passes through the inner side of the two through holes. Both ends of the rack 10 are fixedly connected to the corresponding vertical plate 2. A rotating rod 17 is rotatably mounted on the upper surface of the middle end of the U-shaped plate 16. The lower end of the rotating rod 17 is fixedly connected to the upper end of the hydraulic cylinder 11. The gear 18 is fixedly sleeved on the upper end of the rotating rod 17. The gear 18 meshes with the rack 10.
[0028] Reference Figure 1-3 The clamping mechanism includes a clamping plate 4 and a threaded rod 5. The clamping plate 4 is slidably disposed on the lower side of the L-shaped plate 3. A threaded hole is opened in the middle of the upper surface of the L-shaped plate 3. The threaded rod 5 is threadedly sleeved inside the threaded hole. The lower end of the threaded rod 5 is rotatably connected to the clamping plate 4. Sliding holes are opened on both sides of the threaded hole on the upper surface of the L-shaped plate 3. A sliding rod 6 is slidably sleeved inside the sliding hole. The lower end of the sliding rod 6 is fixedly connected to the clamping plate 4, so that the clamping plate 4 will not rotate with the threaded rod 5, that is, it can move stably.
[0029] In this utility model, when in use, the aluminum profile to be bent is first placed under the L-shaped plate 3 on one side, and the threaded rod 5 is rotated. Since the threaded rod 5 is threaded into the threaded hole on the upper surface of the L-shaped plate 3 and its lower end is rotatably connected to the clamping plate 4, and at the same time, one end of the sliding rod 6 is fixedly connected to the clamping plate 4 and the other end slides in the sliding hole, when the threaded rod 5 is rotated, the clamping plate 4 will move stably under the L-shaped plate 3 until the clamping plate 4 clamps and fixes the aluminum profile.
[0030] Then start the motor 9. The output end of the motor 9 drives the lead screw 7 to rotate. Because the upper end of the U-shaped plate 16 is threadedly connected to the lead screw 7 and both ends are movably connected to the crossbar 8, when the lead screw 7 rotates, the U-shaped plate 16 will slide stably on the crossbar 8 along the axial direction of the lead screw 7, moving the hydraulic cylinder 11 and the bending knife 15 to the side of the workstation where the aluminum profile is placed.
[0031] During the movement of the U-shaped plate 16, the racks 10 with their ends fixedly connected to the vertical plate 2 are inserted through the through holes on both sides of the lower end of the U-shaped plate 16, and the gear 18 fixedly sleeved on the upper end of the rotating rod 17 rotatably disposed on the upper surface of the middle end of the U-shaped plate 16 meshes with the racks 10. Therefore, when the U-shaped plate 16 moves, it will drive the gear 18 to move relative to the racks 10, causing the gear 18 to rotate. The gear 18 drives the rotating rod 17 to rotate, the rotating rod 17 drives the hydraulic cylinder 11 to rotate, and then drives the bending knife 15 to rotate, rotating the bending direction to the side closer to the aluminum profile.
[0032] Next, the hydraulic cylinder 11 is started, and the piston rod of the hydraulic cylinder 11 extends, pushing the push plate 14 to move downward. Since the lower end of the movable rod 13 inside the fixed tube 12 is fixedly connected to the push plate 14, the push plate 14 can move downward stably. The push plate 14 drives the bending knife 15 to move downward, and performs bending operation on the aluminum profile. When the bending knife 15 is pressed down, the clearance groove on the base plate 1 can prevent the bending knife 15 from interfering with the base plate 1.
[0033] After the aluminum profile on one side of the workstation is bent, the motor 9 is started and reversed, causing the U-shaped plate 16 to move the hydraulic cylinder 11 and the bending knife 15 to the top of the other side of the workstation. At this time, the material on the side of the workstation that has been bent can be unloaded, and a new aluminum profile to be bent is placed on the other side of the workstation and clamped and fixed by rotating the threaded rod 5. Then, the above steps are repeated to perform the bending operation on the aluminum profile on the other side of the workstation, realizing the alternating work of the two workstations, reducing the time wasted on changing materials, and improving production efficiency.
[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
