Description

Technical Field

[0001] This utility model relates to the technical field of metal product bending devices, specifically a metal product bending device. Background Technology

[0002] The metal products industry includes the manufacturing of structural metal products, metal tools, containers and metal packaging containers, and stainless steel and similar everyday metal products. With social progress and technological development, metal products are increasingly widely used in industry, agriculture, and all aspects of people's lives, creating ever-increasing value for society.

[0003] In the current technology, most metal products need to be bent during manufacturing. Usually, the metal needs to be aligned with the bending device manually before the bending device is started. The bending device then squeezes and bends the metal. After the blade and groove squeeze the base plate for a long time, the base plate may be worn, which reduces the service life of the device. In addition, the metal is easy to stick to the base plate, making it difficult to remove the bent metal product. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a method for bending metal products, so as to solve the technical problems of damage to the cutting head when in contact with the floor and difficulty in removing metal products.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal product bending device, comprising a stop block, a first rack and a second rack fixedly connected to one side of the stop block, a first gear movably connected to one side of the first rack, a first one-way bearing connected inside the first gear, a third rotating shaft connected inside the first one-way bearing, a reciprocating screw fixedly connected to the outside of the third rotating shaft, a slider movably connected to the outside of the reciprocating screw, a movable plate fixedly connected to the upper end of the slider, a belt movably connected to the outside of the third rotating shaft, a second rotating shaft movably connected to the other side of the belt, a second roller fixedly connected to the outside of the second rotating shaft, a composite fabric connected to the outside of the second roller, a second gear movably connected to one side of the second gear, a second one-way bearing connected inside the second gear, a first rotating shaft connected inside the second one-way bearing, a first roller fixedly connected to the outside of the first rotating shaft, and a composite fabric connected to the outside of the first roller.

[0006] By adopting the above technical solution, this utility model uses a hydraulic rod to push the abutment block downwards. The abutment block drives the second rack to move downwards, thereby driving the second gear to rotate, which in turn drives the first roller to rotate, making the composite cloth in a relaxed state. At this time, the abutment block presses against the upper surface of the metal, cooperating with the bottom plate below to bend the metal. Then, the hydraulic rod resets and the abutment block moves upwards, causing the first rack to move upwards, driving the first gear to rotate, which in turn drives the reciprocating screw to rotate, thereby causing the third rotating shaft to rotate. The third rotating shaft drives the second shaft to rotate via a belt, which in turn drives the second roller to rotate, tightening the composite cloth and lifting the metal on the bottom plate. At the same time, the upper slider of the reciprocating screw moves, driving the movable plate to move and pushing the metal to one side of the device, achieving the effect of easy collection.

[0007] Furthermore, a hydraulic rod is fixedly connected to the upper end of the abutment block, a bracket is fixedly connected to the upper end of the hydraulic rod, and a first mounting plate and a second mounting plate are fixedly connected to both sides of the bracket.

[0008] By adopting the above technical solution, it is easy to control the up and down movement of the block with the hydraulic rod, thereby bending the metal above the base plate.

[0009] Furthermore, a limiting block is connected to the outer side of the second mounting plate, and a second rack is connected inside the limiting block.

[0010] By adopting the above technical solution, the second rack can move up and down, thereby meshing with the second gear and driving the second gear to rotate.

[0011] Furthermore, a base plate is fixedly connected to the inner bottom of the first mounting plate and the second mounting plate, and a groove that mates with the abutment block is provided at the upper end of the base plate.

[0012] By adopting the above technical solution, it is easy for the bottom block to press down and the groove at the top of the base plate to squeeze the metal, thereby achieving the effect of bending the metal.

[0013] Furthermore, a limiting plate is fixedly connected to the inner side of the first mounting plate and the second mounting plate, and a cavity is provided on the inner side of the limiting plate to cooperate with the movable plate.

[0014] By adopting the above technical solution, the slider can easily move the movable plate, thereby allowing the movable plate to push the metal above the base plate for easy collection.

[0015] Furthermore, a limiting ring is movably connected to the outer side of the first rotating shaft, and the limiting ring is fixedly connected to the second mounting plate.

[0016] By adopting the above technical solution, the first rotating shaft can operate stably, thereby driving the first roller to rotate and controlling the composite fabric on the outside of the first roller.

[0017] In summary, the present invention has the following beneficial effects: The present invention uses a hydraulic rod to push the abutment downwards, which in turn moves the second rack downwards, causing the second gear to rotate, which in turn rotates the first roller, thus relaxing the composite fabric. At this time, the abutment presses against the upper surface of the metal, cooperating with the bottom plate to bend the metal. Then, the hydraulic rod resets, and the abutment moves upwards, causing the first rack to move upwards, which in turn rotates the first gear, causing the reciprocating screw to rotate, thus rotating the third shaft. The third shaft, through a belt, drives the second shaft to rotate, thus rotating the second roller, tightening the composite fabric and lifting the metal on the bottom plate. Simultaneously, the upper slider of the reciprocating screw moves, causing the movable plate to move, pushing the metal to one side of the device for easy collection. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] A metal product bending device, as shown in Figures 1-6, includes a stop block 1. A first rack 8 and a second rack 9 are fixedly connected to one side of the stop block 1. A first gear 21 is movably connected to one side of the first rack 8. A first one-way bearing 22 is connected inside the first gear 21. A third rotating shaft 20 is connected inside the first one-way bearing 22. A reciprocating lead screw 6 is fixedly connected to the outside of the third rotating shaft 20. A slider 17 is movably connected to the outside of the reciprocating lead screw 6. A movable plate 10 is fixedly connected to the upper end of the slider 17. A belt 14 is movably connected to the outside of the third rotating shaft 20. A second rotating shaft 19 is movably connected to the other side of the belt 14. A second roller 18 is fixedly connected to the outside of the second rotating shaft 19. A composite cloth 12 is connected to the outside of the second roller 18. A second gear 25 is movably connected to one side of the second gear 9. A second one-way bearing 23 is connected inside the second gear 25. A first rotating shaft 16 is connected inside the second one-way bearing 23. A first roller 13 is fixedly connected to the outer side of the first rotating shaft 16, and a composite cloth 12 is connected to the outer side of the first roller 13. In this invention, the hydraulic rod 2 pushes the abutment 1 downward, which drives the second rack 9 to move downward, thereby driving the second gear 25 to rotate, which in turn drives the first roller 13 to rotate, so that the composite cloth 12 is in a relaxed state. At this time, the abutment 1 presses against the upper surface of the metal and cooperates with the bottom plate 15 below to bend the metal. At this time, the hydraulic rod 2 resets and the abutment moves upward, which causes the first rack 8 to move upward, driving the first gear 21 to rotate, which causes the reciprocating screw 6 to rotate, thereby causing the third rotating shaft 20 to rotate. The third rotating shaft 20 drives the second rotating shaft 19 to rotate through the belt 14, thereby causing the second roller 18 to rotate, tightening the composite cloth 12, thereby lifting the metal on the bottom plate 15. At the same time, the upper slider 17 of the reciprocating screw 6 moves, driving the movable plate 5 to move, pushing the metal to one side of the device, so as to achieve the effect of easy collection.

[0028] Please see Figure 1 A hydraulic rod 2 is fixedly connected to the upper end of the abutment block 1, and a bracket 3 is fixedly connected to the upper end of the hydraulic rod 2. A first mounting plate 4 and a second mounting plate 7 are fixedly connected to both sides of the bracket 3. By setting the above structure, this utility model facilitates the hydraulic rod 2 to control the up and down movement of the abutment block 1, thereby bending the metal above the base plate 15.

[0029] Please see Figure 2 The second mounting plate 7 is connected to a limiting block 11 on its outer side, and the limiting block 11 is connected to a second rack 9 inside. By setting the above structure, this utility model facilitates the up and down movement of the second rack 9, so as to mesh with the second gear 25 and drive the second gear 25 to rotate.

[0030] Please see Figure 2The bottom inner side of the first mounting plate 4 and the second mounting plate 7 is fixedly connected to the base plate 15, and the upper end of the base plate 15 is provided with a groove that cooperates with the abutment 1. By setting the above structure, this utility model makes it easy for the abutment 1 to press down and squeeze the metal with the groove at the upper end of the base plate 15, thereby achieving the effect of bending the metal.

[0031] Please see Figure 2 The first mounting plate 4 and the second mounting plate 7 are fixedly connected to the inner side of the limiting plate 5, and the inner side of the limiting plate 5 is provided with a cavity that cooperates with the movable plate 10. By setting the above structure, the present invention facilitates the slider 17 to drive the movable plate 10 to move, thereby allowing the movable plate 10 to push the metal above the base plate 15 for easy collection.

[0032] Please see Figure 6 A limiting ring 23 is movably connected to the outer side of the first rotating shaft 16, and the limiting ring 23 is fixedly connected to the second mounting plate 7. By setting the above structure, this utility model facilitates the stable operation of the first rotating shaft 16, thereby driving the first roller 13 to rotate and controlling the composite cloth 12 on the outer side of the first roller 13.

[0033] The working principle of this utility model is as follows: When in use, the operator places the metal to be bent on the composite cloth, starts the hydraulic rod 2, and the hydraulic cylinder 2 pushes downward, causing the abutment 1 to move downward. At this time, the abutment 1 drives the first rack 8 and the second rack 9 on the side to move downward. The first rack 8 meshes with the first gear 21, thereby driving the first gear 21 to rotate. The first gear 21 has a first one-way bearing installed inside, so that the first rack 8 is in a sliding state when it moves downward. The second rack 9 meshes with the second gear 25, thereby driving the second gear 25 to rotate. The second gear 25 drives the internal second one-way bearing 23 to rotate, thereby driving the first rotating shaft 16 to rotate. The first rotating shaft 16 drives the first roller 13 to rotate, thereby causing the composite cloth 12 around the first roller 13 to be in a relaxed state.

[0034] At the same time, the abutment 1 moves downward, pressing the upper surface of the metal and the lower surface of the metal adheres to the composite cloth. Together, they are pressed into the groove on the base plate 15 by the abutment 1, bending the metal.

[0035] At this time, the hydraulic rod 1 moves upward, causing the stop block 1 to move upward. The stop block 1 causes the first rack 8 and the second rack 9 to move upward. The second rack 9 causes the second gear 25 to rotate. At this time, the second one-way bearing 23 inside the second gear 25 is in a slipping state. The first rack 8 causes the first gear 21 to rotate. The first gear 21 causes the first one-way bearing 22 inside to rotate. The first one-way bearing 22 causes the third rotating shaft 20 to rotate, thereby causing the reciprocating screw 6 to rotate. At the same time, the third rotating shaft 20 rotates the belt 14 at the other end, thereby causing the second rotating shaft 19 to rotate. The second rotating shaft 19 causes the second roller 18 to rotate, thereby tightening the composite cloth 12 on the outside of the second roller 18 and lifting the metal above the composite cloth 12 from the groove on the base plate 15. At the same time, the reciprocating screw 6 rotates, causing the slider 17 to move. The slider 17 causes the movable plate 10 to move, thereby causing the movable plate 10 to push the metal above the base plate 1, pushing the metal to one side of the device. At this time, the worker can collect the pushed metal.
