Common bending mechanisms include manual bending machines, hydraulic bending machines, and numerical control bending machines, etc. They are widely used in fields such as metal processing, construction, and automobile manufacturing, and are one of the important devices for realizing the processing and production of metal products.

[0003] In the existing bending machine technology, the bending of steel wires is usually to convey the steel wires on a flat workbench and adjust the position back and forth so that the steel wires are at the bending position, and then rotate and extrude through a bending die at a fixed position to realize the bending of the steel wires. However, since the existing device can only realize bending in the plane direction, there are great limitations. When bending in other directions is required, manual adjustment by the operator is needed, resulting in a relatively low overall work efficiency. In addition, when it is necessary to change the arc diameter of the bending position, traditional bending machines often need to replace or adjust the die, which not only takes time and effort but also limits the flexibility in the production process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1:

[0022] Please refer to Figures 1 - 3 , the present invention discloses an automatic bending mechanism for a bending machine, including a fixing plate 1. One side of the fixing plate 1 is fixedly connected with a steel wire outlet 2. The outside of the steel wire outlet 2 is rotatably connected with a turntable 3. One side of the turntable 3 is fixedly connected with two fixing blocks 4. One side of each of the two fixing blocks 4 is fixedly connected with an electric push rod 6. The telescopic ends of the two electric push rods 6 extend to the other side of the fixing blocks 4. One ends of the two electric push rods 6 are respectively fixedly connected with a first sliding plate 7 and a second sliding plate 8. A bending assembly is arranged on one side of the first sliding plate 7, and an adjusting assembly is arranged on one side of the second sliding plate 8. Two first chutes 5 are opened on one side of the turntable 3. The first sliding plate 7 and the second sliding plate 8 are respectively slidably connected inside the two first chutes 5.

[0023] On the other side of the fixing plate 1, a gear ring 12 and a gear 13 are rotatably connected. The gear ring 12 is fixedly connected with the turntable 3. The gear ring 12 is meshed with the gear 13. A second motor 14 is also installed on the other side of the fixing plate 1. The output end of the second motor 14 is fixedly connected with the gear 13.

[0024] The bending assembly includes a first rotating plate 9. The first rotating plate 9 is rotatably connected to one side of the first sliding plate 7. The top surface of the first rotating plate 9 is fixedly connected with a groove block 10. On the other side of the first sliding plate 7, a first motor 11 is fixedly connected. The output end of the first motor 11 is fixedly connected with the first rotating plate 9.

[0025] On the other side of the second sliding plate 8, a third rotating plate 24 is rotatably connected. The third rotating plate 24 is fixedly connected with a second rotating plate 15. The top surfaces of the third rotating plate 24 and the second sliding plate 8 are respectively fixedly connected with short rods 25. A second return spring 26 is installed between the two short rods 25.

[0026] Specifically, when it is necessary to adjust the turning direction, the rotation of the output end of the second motor 14 drives the gear 13 to rotate, and the gear 13 drives the engaged ring gear 12 to rotate. Furthermore, the rotation of the ring gear 12 causes the turntable 3 connected to the ring gear 12 to rotate synchronously, so that the two fixed blocks 4 rotate around the steel wire outlet 2 as the center, thereby adjusting the bending direction, solving the problem that the existing device can only achieve bending in the plane direction and has great limitations. When bending, the rotation of the second rotating plate 15 drives the synchronous rotation of the third rotating plate 24 on the other side of the second sliding plate 8, so that the second return spring 26 between the third rotating plate 24 and the two short rods 25 fixedly connected to the top surface of the second sliding plate 8 is stretched. When a bending is completed, the third rotating plate 24 together with the adjusting assembly is reset by the rebound of the second return spring 26. Embodiment 2:

[0027] Based on the above Embodiment 1, please refer to Figure 4 and Figure 5 The adjusting assembly includes a second rotating plate 15. The second rotating plate 15 is rotatably connected to one side of the second sliding plate 8. Two vertical plates 16 are fixedly connected to the top surface of the second rotating plate 15. A rotating roller 17 is rotatably connected between the two vertical plates 16. Four second sliding grooves 19 are formed on the outer surface of the rotating roller 17. A third motor 18 is fixedly installed on one side of one of the vertical plates 16. The output end of the third motor 18 is fixedly connected to the rotating roller 17.

[0028] The adjusting assembly further includes eight sliding blocks 20. The eight sliding blocks 20 are grouped in pairs. The four groups of sliding blocks 20 are respectively slidably connected inside the four second sliding grooves 19. A first return spring 21 is fixedly connected between each group of sliding blocks 20.

[0029] Two bending rods 22 are respectively fixedly connected to the top surface of each group of sliding blocks 20. The diameters of the bending rods corresponding to the top surfaces of each group of sliding blocks are different. Two triangular blocks 23 are fixedly connected to the top surfaces of every two bending rods 22. The top surface of the triangular block 23 is in movable contact with the inside of the groove block 10.

[0030] Specifically, the rotation of the output end of the third motor 18 drives the rotating roller 17 to rotate, so that the four second sliding grooves 19 formed on the outer surface of the rotating roller 17 are switched. Each group of sliding blocks 20 slidably connected inside the four second sliding grooves 19 are respectively provided with bending rods 22 of different diameters at the top surfaces. The steel wire is clamped and rotated by the two bending rods 22 of different diameters, realizing the function of adjustable arc diameter at the bending place, and can flexibly adjust the bending arc diameter of the steel wire according to the requirements of different products, so as to meet the diversified production requirements.

[0031] Working principle and usage process of the utility model: When it is necessary to bend a steel wire using a steel wire bender, the steel wire will be conveyed out from the steel wire outlet 2 fixedly connected to one side of the fixed plate 1. By respectively pushing the first sliding plate 7 and the second sliding plate 8 to slide in the first chute 5 through two electric push rods 6, the first sliding plate 7 and the second sliding plate 8 move relatively, and two triangular blocks 23 are inserted into the groove block 10. Since the outer inclined surfaces of the two triangular blocks 23 are adapted to the inner wall of the groove block 10, the two triangular blocks 23 drive the two sliding blocks 20 to move relatively in the second chute 19, so that the two bending rods 22 can clamp the steel wire. Then, the rotation of the output end of the first motor 11 drives the groove block 10 to rotate. At this time, the two triangular blocks 23 are inserted into the groove block 10, so the whole adjusting assembly on one side of the second sliding plate 8 rotates, and thus the two bending rods 22 clamping and fixing the steel wire rotate around the center, and the bending of the steel wire to the left or right is completed by the rotation and extrusion of the bending rods 22. When bending, the rotation of the second rotating plate 15 drives the third rotating plate 24 on the other side of the second sliding plate 8 to rotate synchronously, so that the second return spring 26 between the third rotating plate 24 and the two short rods 25 fixedly connected to the top surface of the second sliding plate 8 is stretched. When one bending is completed, the first sliding plate 7 and the second sliding plate 8 are respectively driven by the two electric push rods 6 to move and separate the triangular blocks 23 from the groove block 10. At this time, through the resilience of the second return spring 26, the third rotating plate 24 together with the adjusting assembly is reset, facilitating the next bending.

[0032] When it is necessary to adjust the bending direction, the rotation of the output end of the second motor 14 drives the gear 13 to rotate, and the gear 13 drives the engaged gear ring 12 to rotate. Then, through the rotation of the gear ring 12, the turntable 3 connected to the gear ring 12 rotates synchronously, so that the two fixed blocks 4 rotate around the steel wire outlet 2 as the center, thereby adjusting the bending direction, solving the problem that the existing device can only achieve bending in the plane direction and has great limitations.

[0033] The rotation of the output end of the third motor 18 drives the rotating roller 17 to rotate, so that the four second chutes 19 opened on the outer surface of the rotating roller 17 are switched. Each group of sliding blocks 20 slidably connected inside the four second chutes 19 are respectively installed with bending rods 22 of different diameters. By clamping and rotating the steel wire with the two bending rods 22 of different diameters, the function of adjusting the arc diameter at the bending place is realized, and the bending arc diameter of the steel wire can be flexibly adjusted according to the requirements of different products, so as to meet the diversified production requirements.
