Description

Technical Field

[0001] This utility model belongs to the field of polyethylene profile production, specifically a polyethylene profile bending device. Background Technology

[0002] Polyethylene profiles are industrial profiles made primarily of polyethylene (PE). They are widely used in various industries, such as construction, machinery, electronics, and chemicals. Polyethylene is one of the most common thermoplastics and has good chemical stability, wear resistance, corrosion resistance, and electrical insulation properties.

[0003] In the existing technology, the bending of polyethylene profiles is mostly carried out manually in conjunction with bending devices. However, the existing bending devices are relatively simple in function, only able to achieve a single bending radius, and lack the function of adjusting the bending radius. This means that when bending with different radii is required, other models of bending devices need to be replaced, which is quite troublesome and not conducive to improving processing efficiency.

[0006] In a preferred embodiment, the adjustment assembly includes an adjustment screw and a linkage unit.

[0007] In a preferred embodiment, the linkage unit includes a first bevel gear, which is fixedly connected to the outside of the motor output end. A worm gear is rotatably connected to the outside of the worktable via a limiting block. A second bevel gear is fixedly connected to one end of the worm gear.

Slide plates are slidably connected at equal intervals to the multiple arc-shaped blocks inside the fixed frame. Multiple springs are respectively provided between the outside of the fixed frame and the multiple arc-shaped plates.

[0008] In a preferred embodiment, the adjustment assembly further includes sliders, which are slidably connected to the interiors of two rotating frames respectively.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1-5 A polyethylene profile bending device includes a workbench 1, a lifting platform 2 slidably connected to one side of the top of the workbench 1, a limit frame 3 symmetrically fixedly connected to one side of the top of the lifting platform 2, a clamping plate 4 slidably connected to the inner side of the limit frame 3, a fixed frame 5 fixedly connected to one side of the outer of the workbench 1, an arc plate 6 slidably connected to the outer side of the fixed frame 5 at equal intervals, a rotating frame 7 rotatably connected to both sides of the outer of the fixed frame 5, a bending column 9 slidably connected to the inner side of the two rotating frames 7, and an adjustment component provided on the outer side of the workbench 1.

[0022] Specifically, the adjustment assembly includes an adjusting screw 10 and a linkage unit. The adjusting screw 10 is rotatably connected to the outer side of the worktable 1 via a limit block. A motor 11 is fixedly connected to the outer side of the worktable 1 and below the adjusting screw 10 via a mounting block. The output end of the motor 11 is fixedly connected to the adjusting screw 10. The outer side of the lifting platform 2 is connected to the outer side of the adjusting screw 10 via a screw-nut pair. The arc plate 6 can slide through the linkage unit. The linkage unit includes a first bevel gear 12, which is fixedly connected to the outer side of the output end of the motor 11. A worm gear 13 is rotatably connected to the outer side of the worktable 1 via a limit block. One end of the worm gear 13 is fixedly connected to a second bevel gear 14. The first bevel gear 12 meshes with the second bevel gear 14. The fixed frame 5 is rotatably connected to a rotating column 15 inside. One end of the rotating column 15 extends through a rotating shaft to the outside of the fixed frame 5 and is fixedly connected to a worm gear 16. The worm gear 16 meshes with a worm 13. Arc-shaped blocks 17 are fixedly connected at equal intervals to the outside of the rotating column 15. Slide plates 18 are slidably connected at equal intervals to the multiple arc-shaped blocks 17 inside the fixed frame 5. Multiple springs 19 are respectively provided between the outside of the fixed frame 5 and the multiple arc-shaped plates 6. The adjustment assembly also includes sliders 8, which are slidably connected to the inside of two rotating frames 7. A bending column 9 is fixedly connected between the two sliders 8. A second screw 21 is threadedly connected to one side of the top of the rotating frame 7. The bottom of the second screw 21 extends into the inside of the rotating frame 7 and is rotatably connected to the corresponding slider 8.

[0023] The above technical solution involves first placing the profile to be bent on top of the lifting platform 2, then passing it under the clamping plate 4 and bending column 9. Rotating the two first screws 20 causes the clamping plate 4 to move downwards until the profile is clamped on one side by the two clamping plates 4. Then, manually pushing the handrail causes the rotating frame 7 and bending column 9 to rotate, thus bending the profile under the support of multiple arc plates 6. After bending, the profile can be disassembled and removed. When the bending radius needs to be adjusted, the motor 11 is started by the external controller. The output end of the motor 11 drives the adjusting screw 10 and the first bevel gear 12 to rotate, causing the adjusting screw 10 to drive the lifting platform 2 to rise through the screw nut pair. At the same time, the first bevel gear 12 can drive the second bevel gear 14 and the worm gear 13 to rotate through meshing. The worm gear 13 then drives the worm wheel 16 and the rotating column 15 to rotate through meshing. 5 drives multiple external arc-shaped blocks 17 to rotate, causing the arc-shaped blocks 17 to push the corresponding slide plates 18 to slide outwards. The slide plates 18 then push the corresponding arc-shaped plates 6 to slide outwards, while stretching the springs 19, causing the springs 19 to deform. The top of the upper arc-shaped plate 6 is always flush with the lifting platform 2. After adjusting to the required bending radius, the motor 11 is turned off, and then the second screw 21 is rotated, causing the slider 8 and the bending column 9 to move inside the rotating frame 7. This allows for corresponding adjustments, enabling the bending column 9 to better bend the profile. This device has a simple structure and can bend the profile by pushing the bending column 9 through simple operation. When it is necessary to adjust the bending radius of the profile, the height of the lifting platform 2 and the extension distance of the arc-shaped plate 6 can be adjusted accordingly, thereby arbitrarily adjusting the bending radius, effectively improving the practicality and flexibility of the device.

[0024] Specifically, the top of the limiting frame 3 is threaded with a first screw 20, the bottom of the first screw 20 extends to the inside of the limiting frame 3 and is rotatably connected to the clamping plate 4, the outside of the rotating frame 7 is fixedly connected with a handrail, the motor 11 is electrically connected to an external controller, and the top of the lifting platform 2 is fixedly connected with a rubber pad.

[0025] Through the above technical solution, the motor 11 can be quickly controlled by the staff through the external controller, and the rubber pad can further improve the stability when bending the profile.

[0026] In use, first place the profile to be bent on top of the lifting platform 2, then pass it under the clamping plate 4 and bending column 9. Rotating the two first screws 20 will drive the clamping plate 4 downward until the profile is clamped on one side by the two clamping plates 4. Then, manually push the handle to drive the rotating frame 7 and bending column 9 to rotate, so that the profile can be bent under the support of multiple arc plates 6. After bending, it can be disassembled and taken out. When it is necessary to adjust the bending radius, start the motor 11 through the external controller. The output end of the motor 11 drives the adjusting screw 10 and the first bevel gear 12 to rotate, so that the adjusting screw 10 drives the lifting platform 2 to rise through the screw nut pair. At the same time, the first bevel gear 12 can drive the second bevel gear 14 and the worm gear 13 to rotate through the meshing relationship. The worm gear 13 then drives the worm wheel 16 and the rotating column 15 to rotate through the meshing relationship. The rotating column 15 drives the multiple external arc blocks 17 to rotate, so that the multiple arc blocks 17 push the multiple arc blocks 17 to push the multiple arc blocks 17 to rotate. The corresponding slide plate 18 slides outward, and the slide plate 18 then pushes the corresponding arc plate 6 to slide outward, while stretching the spring 19, causing the spring 19 to deform. The top of the upper arc plate 6 is always flush with the lifting platform 2. After adjusting to the required bending radius, the motor 11 is turned off, and then the second screw 21 is rotated, driving the slider 8 and the bending column 9 to move inside the rotating frame 7, so that the corresponding adjustment can be made, allowing the bending column 9 to bend the profile better. This device has a simple structure, and the bending column 9 can be pushed to bend the profile through simple operation. When it is necessary to adjust the bending radius of the profile, it can be adjusted by adjusting the height of the lifting platform 2 and the extension distance of the arc plate 6, so that the bending radius can be adjusted arbitrarily, effectively improving the practicality and flexibility of the device. The motor 11 can be quickly controlled by the operator through the external controller, and the rubber pad can further improve the stability when bending the profile.
