Description

A wire drawing machine with a tension control structure Technical Field

[0001] This utility model belongs to the technical field of metal wire drawing machines, specifically a wire drawing machine with a tension control structure. Background Technology

[0002] A wire drawing machine is an industrial device used to draw metal materials into fine wires or cables through stretching. It is widely used in the fields of wire and cable, metal products, and precision material processing. Its core process involves gradually reducing the cross-sectional area of ​​the metal billet through multiple stretching dies, while simultaneously improving the material's ductility and mechanical properties.

[0003] Existing technologies have the following shortcomings: In existing wire drawing machine tension control mechanisms, the lack of real-time, precise tension feedback and adaptive adjustment capabilities prevents the system from dynamically adjusting according to the actual tension of the wire. This limitation leads to the wire potentially becoming slack due to insufficient tension during the stretching process, affecting the wire's dimensional accuracy and surface quality. Simultaneously, when the tensioning mechanism responds lagily or adjusts excessively, it can easily cause the wire to be over-tensioned, even resulting in wire breakage or internal stress concentration. Furthermore, traditional tension control relies heavily on manual experience or fixed parameter settings, making it difficult to adapt to production needs involving different materials, wire diameters, and speeds. This not only reduces production efficiency but also increases scrap rates and equipment maintenance costs. Summary of the Invention

[0004] To overcome the above-mentioned defects, this utility model provides a wire drawing machine with a tension control structure, which solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire drawing machine with a tension control structure, comprising:

[0006] The control box has two A-slide grooves and one B-slide groove. The two A-slide grooves are distributed on both sides of the B-slide groove. The inner walls of both sides of the control box are slidably connected with mating toothed plates. The side walls of the control box are slidably connected with double-sided toothed plates. The bottom of the control box is fixedly connected with an electric telescopic rod. The output end of the electric telescopic rod is fixedly connected to the double-sided toothed plates.

[0007] The control box contains two mating gears that mesh with a mating toothed plate on one side and a double-sided toothed plate on both sides. A mounting base is fixedly connected to the double-sided toothed plate, and a secondary guide roller is fixedly connected to the mating toothed plate.

[0008] As a further embodiment of this utility model: two telescopic rods are fixedly connected to the mounting base, and a rotating seat is fixedly connected to the output end of the two telescopic rods.

[0009] As a further embodiment of this utility model: a buffer spring is sleeved on the outside of the telescopic rod, and the two ends of the buffer spring abut against the mounting base and the rotating base respectively.

[0010] As a further embodiment of this utility model: a main guide roller is rotatably connected inside the rotating seat.

[0011] As a further embodiment of this utility model: a sliding rheostat is fixedly connected to the rotating seat, and the slider of the sliding rheostat is fixedly connected to the mounting base.

[0012] As a further embodiment of this utility model: the sliding rheostat is electrically connected to the electric telescopic rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a sliding rheostat. When the metal wire on the main guide roller is not taut, the telescopic rod and buffer spring extend to their initial positions, causing a change in the resistance of the sliding rheostat. The electric telescopic rod, which is electrically connected to the sliding rheostat, then extends, causing the main guide roller and the secondary guide roller to move away from each other, thus tauting the metal wire again. This tautness mechanism requires no manual control and can be automated, making it more convenient and faster. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] As shown in Figures 1-3, this utility model provides a technical solution:

[0021] A wire drawing machine with a tension control structure includes:

[0022] The control box 1 has two A-slide grooves and one B-slide groove. The two A-slide grooves are distributed on both sides of the B-slide groove. The inner walls on both sides of the control box 1 are slidably connected with mating toothed plates 2. The side walls of the control box 1 are slidably connected with double-sided toothed plates 3. The bottom of the control box 1 is fixedly connected with an electric telescopic rod 4. The output end of the electric telescopic rod 4 is fixedly connected to the double-sided toothed plates 3.

[0023] Two mating gears 5 are rotatably connected inside the control box 1. The mating gears 5 mesh with the mating tooth plate 2 and the double tooth plate 3 on the corresponding side. The double tooth plate 3 is fixedly connected to the mounting seat 6, and the mating tooth plate 2 is fixedly connected to the secondary guide roller 7. The mounting seat 6 is slidably connected in the A slide groove, and the secondary guide roller 7 is slidably connected in the B slide groove. When the electric telescopic rod 4 extends or retracts, the double tooth plate 3 fixedly connected to it will move up and down. Since the double tooth plate 3 meshes with the mating gears 5, the mating gears 5 will rotate. The mating tooth plate 2 meshing with the mating gears 5 will move in the opposite direction to the movement direction of the double tooth plate 3, thereby causing the mounting seat 6 and the secondary guide roller 7 to move relative to each other.

[0024] Two telescopic rods 8 are fixedly connected to the mounting base 6. A rotating seat 9 is fixedly connected to the output end of the two telescopic rods 8. A buffer spring 10 is sleeved on the outside of the telescopic rods 8. The two ends of the buffer spring 10 abut against the mounting base 6 and the rotating seat 9 respectively. A main guide roller 11 is rotatably connected inside the rotating seat 9. A sliding rheostat 12 is fixedly connected to the rotating seat 9. The slider of the sliding rheostat 12 is fixedly connected to the mounting base 6. The sliding rheostat 12 is electrically connected to the electric telescopic rod 4. The metal wire is wound through the main guide roller 11 and the secondary guide roller 7. When the metal wire on the main guide roller 11 is not taut, the telescopic rod 8 and the buffer spring 10 will extend to the initial position, causing the resistance of the sliding rheostat 12 to change. The electric telescopic rod 4, which is electrically connected to the sliding rheostat 12, will extend, thereby causing the main guide roller 11 and the secondary guide roller 7 to move away from each other, so that the metal wire is taut again.

[0025] The working principle of this utility model is as follows:

[0026] Mounting base 6 is slidably connected to groove A, and secondary guide roller 7 is slidably connected to groove B. When the electric telescopic rod 4 extends or retracts, the double-sided toothed plate 3 fixedly connected to it will move up and down. Since the double-sided toothed plate 3 meshes with the mating gear 5, the mating gear 5 will rotate, and the mating toothed plate 2 meshing with the mating gear 5 will move in the opposite direction to the movement direction of the double-sided toothed plate 3, thereby causing the mounting base 6 and the secondary guide roller 7 to move relative to each other.

[0027] The metal wire is wound through the main guide roller 11 and the secondary guide roller 7. When the metal wire on the main guide roller 11 is not taut, the telescopic rod 8 and the buffer spring 10 will extend to the initial position, causing the resistance of the sliding rheostat 12 to change. The electric telescopic rod 4, which is electrically connected to the sliding rheostat 12, will extend, thereby causing the main guide roller 11 and the secondary guide roller 7 to move away from each other, so that the metal wire is taut again.

[0028] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
