[0002] Resistance wire bending devices have a wide range of applications in the field of material processing, particularly in applications where materials need to be bent into specific shapes to suit design requirements. However, traditional resistance wire bending devices have significant limitations in terms of operational efficiency and automation. In traditional resistance wire bending processes, materials are typically manually manipulated, which is not only inefficient but also increases operational complexity and labor costs. Although existing technologies incorporate automatic feeding, the process still requires a pause to operate the bending operation when it reaches the bending area, resulting in a lack of continuity.

[0005] Therefore, it is necessary to design a resistance wire bending device that is practical and continuous. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 The utility model provides a technical solution: a resistance wire hot bending device, including a base 1, a motor 2 is fixedly connected to the inner side of the base 1, the output end of the motor 2 is provided with a rotating shaft 21, one side of the rotating shaft 21 is connected to an intermittent mechanism, one side of the intermittent mechanism is connected to a rotating mechanism, a first cylinder 3 is fixedly connected to the inner side of the base 1, the output end of the first cylinder 3 is connected to a first piston rod 31, one side of the first piston rod 31 is connected to an adjusting mechanism, the adjusting mechanism and the rotating mechanism are connected, an operating table 4 is provided on one side of the base 1, the inner side of the operating table 4 is fixedly connected to a lifting mechanism, one side of the lifting mechanism is connected to a hot bending block 52, the inner bottom of the operating table 4 is fixedly connected to a positioning block 41, the inner bottom of the operating table 4 is fixedly connected to an operating plate 42, a groove 43 is provided inside the operating plate 42, and the hot bending block 52 and the groove 43 are connected. 3. When the operator is ready to begin hot bending, they first pass the resistance wire between the two rollers and through the positioning block 41, ensuring that the resistance wire is oriented in the same direction. Then, the first cylinder 3 is turned on, and the first piston rod 31 at the output end extends outward. The adjustment mechanism moves the upper roller downward, thereby adjusting the distance between the two rollers to accommodate the size of the resistance wire. The operator then turns on the motor 2, rotating the rotating shaft 21, causing the rotating mechanism to rotate the two rollers, automatically feeding the resistance wire forward and achieving automatic feeding. Simultaneously with the motor 2 being turned on, the intermittent mechanism also operates, causing the two rollers to pause while feeding. During this pause, the lifting mechanism lowers the bending block 52, pressing it into the groove 43 to bend the wire. After the bending is complete, it rises, and the two rollers continue rotating, carrying the resistance wire out of the device. The provision of the rotating mechanism enables automatic feeding of the resistance wire, improving production efficiency and reducing reliance on manual operation, thereby reducing labor costs. The provision of the intermittent mechanism coordinates automatic feeding and pausing, ensuring continuous operation of the resistance wire and improving work efficiency. The provision of the adjustment mechanism allows the distance between the rollers to be adjusted to accommodate resistance wires of varying sizes. This flexibility enables the device to handle resistance wires of various specifications, enhancing its versatility and practicality.

[0025] The intermittent mechanism includes a first gear 22, which is fixedly connected to the rotating shaft 21. A second gear 23 is meshed with one side of the first gear 22, which is connected to the rotating mechanism. When the operator turns on the motor 2, the rotating shaft 21 rotates, rotating the first gear 22, which in turn rotates the meshed second gear 23, which in turn rotates the rotating mechanism. The intermittent mechanism allows the device to automatically feed and pause, allowing the hot bending process to be completed during the pause. The device operates in an orderly manner, requiring no manual operation and achieving high overall accuracy.

[0026] The first gear 22 is an incomplete gear; the first gear 22 has only partial teeth, so that the partial teeth engage with the second gear 23 and can drive the second gear 23 to rotate. When the first gear 22 rotates to the part without teeth corresponding to the second gear 23, the second gear 23 will not rotate at this time, and the device starts to perform hot bending work.

[0027] The rotating mechanism includes a vertical rod 11, the vertical rod 11 and the interior of the base 1 are rotatably connected, the vertical rod 11 and the second gear 23 are fixedly connected, the outer side of the vertical rod 11 is connected to two first bevel gears 12, one side of the upper first bevel gear 12 is meshed with the second bevel gear 36, the second bevel gear 36 is connected to the adjusting mechanism, and one side of the lower first bevel gear 12 is meshed with the third bevel gear 14, the inner bottom of the base 1 is fixedly connected to two support seats 15, the middle part of the support seat 15 is rotatably connected to the first cross bar 16, the outer side of the first cross bar 16 is fixedly connected to the first roller 17, the first roller 18 is fixedly connected to the first roller 19, and the second roller 19 is fixedly connected to the first roller 19. A cross bar 16 is fixedly connected to the third bevel gear 14; when the second gear 23 rotates, it also rotates the fixedly connected vertical bar 11, and the top of the vertical bar 11 and the inside of the base 1 are rotationally connected, so they can rotate under the drive of the second gear 23, and then the two first bevel gears 12 will rotate, and the meshing third bevel gear 14 and the second bevel gear 36 will rotate, the two cross bars rotate, and the first roller 17 and the second roller 35 rotate. The two rotation directions are opposite, so the internal resistance wire can be pushed forward, thereby realizing automatic feeding of the resistance wire and improving work efficiency.

[0028] The two first bevel gears 12 are in opposite directions, the lower first bevel gear 12 and the vertical rod 11 are fixedly connected, the upper first bevel gear 12 and the vertical rod 11 are slidingly connected, and the upper first bevel gear 12 is connected to the adjustment mechanism; the lower first bevel gear 12 does not need to move, but the upper first bevel gear 12 needs to be able to move up and down, so that it can cooperate with the adjustment mechanism to realize the movement of the second roller 35 and the adjustment of the internal distance, so that it can adapt to resistance wires of different sizes.

[0029] The adjusting mechanism includes a U-shaped block 32, a first piston rod 31 and a U-shaped block 32 are fixedly connected, the inner side of the U-shaped block 32 is rotatably connected to the second cross bar 34, the outer side of the second cross bar 34 is fixedly connected to the second roller 35, the second cross bar 34 and the second bevel gear 36 are fixedly connected, one side of the U-shaped block 32 is fixedly connected to a fixed block 33, the fixed block 33 is connected to the vertical rod 11, and the fixed block 33 and the first bevel gear 12 are rotatably connected; when the staff opens the first cylinder 3, the first piston rod 31 extends downward, and the U-shaped block 32 is lowered, so that The second cross bar 34 that is internally rotatably connected descends, the second roller 35 descends, and the fixed block 33 and the first bevel gear 12 are rotatably connected, which means that they are connected to the first bevel gear 12. In this way, the fixed block 33 descends and the first bevel gear 12 descends. Therefore, the first bevel gear 12 and the vertical bar 11 are slidably connected, so they can descend. At the same time as the first bevel gear 12 descends, the third bevel gear 14 also descends driven by the U-shaped block 32, and the upper part descends as a whole to achieve distance adjustment. The device can adapt to resistance wires of different sizes and has strong adaptability.

[0030] Two long strips 13 are fixedly connected to the outside of the vertical rod 11, and two long grooves are provided on the inner side of the first bevel gear 12 above, and the long strips 13 correspond to the long grooves; because the first gear 22 and the vertical rod 11 are slidingly connected, when the vertical rod 11 rotates, the first gear 22 cannot be driven to rotate. Therefore, the long strip 13 is fixedly connected to the outside of the vertical rod 11, and the top of the first bevel gear 12 above is fixedly connected to the ring, and the outside of the ring is rotatably connected to the fixed block 33. In this way, long grooves are provided inside the first bevel gear 12 and the inside of the ring, and the long strips 13 are inside the long grooves. When the vertical rod 11 rotates, the long strips 13 rotate, pressing the inner side of the long grooves to drive the first bevel gear 12 to rotate, thereby realizing that the first bevel gear 12 can rotate and be adjusted up and down.

[0031] The lifting mechanism includes a second cylinder 5, which is fixedly connected to the inner top of the operating table 4. The output end of the second cylinder 5 is connected to the second piston rod 51, and the second piston rod 51 and the hot bending block 52 are fixedly connected; when the staff opens the second cylinder 5, the second piston rod 51 extends, and descends with the hot bending block 52, pressing into the inside of the groove 43 to perform hot bending on the resistance wire.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
