Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a torque adjustment mechanism for a winch. Background Technology

[0002] In the manufacturing of wires and cables, metal products and other industries, the bow stranding machine is the core equipment for realizing the stranding of multiple metal single wires into cables. It twists the single wires into stranded conductors with specific strength and conductivity through a rotating stranding action.

[0003] Traditional wire guide plates have straight hole structures for the wires. Straight hole structures do not have a guiding function. Unguided single wires are prone to deviation in their path when subjected to force, resulting in force deviation and local defects. At the same time, the straight hole structure cannot promptly remove metal debris generated during processing, which can easily cause friction on the single wire and affect its quality.

[0004] Therefore, a torque adjustment mechanism for a bow winch is proposed to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] Please see Figure 1 - Figure 5 The torque adjustment mechanism of a bow winch in this embodiment includes a base 1 and a rotary motor 3. Several movable guards 2 are slidably arranged on the upper end of the base 1. Several bearing seats 16 are fixedly arranged on the upper surface of the base 1. A wire outlet shaft 7 is arranged through the center of the bearing seat 16. Several supports 17 are fixedly arranged on the upper end of the base 1. The supports 17 are arranged in an array at the center of the upper end of the base 1. A connecting shaft 8 is rotatably arranged inside the support 17. A rotating disk 4 is fixedly arranged at one end of the connecting shaft 8 near the rotary motor 3. Several connecting rods 18 are fixedly arranged inside the rotating disk 4. A wire guide plate 5 and a stranding plate 6 are fixedly arranged on the outside of the connecting rods 18. At least five wire guide wheels 19 are rotatably arranged inside the wire guide plate 5. An arched cradle 13 is fixedly arranged at the other end of the connecting shaft 8. A wire reel 11 is rotatably arranged inside the arched cradle 13. A wire inlet shaft seat 12 is rotatably arranged on the outside of the support 17 farthest from the rotary motor 3. When stranding is performed, the single metal wire is inserted into the inlet shaft seat 12, led out through the wire reel 11, passes through the rotating disk 4, the wire guide plate 5, and the stranding plate 6, and is connected to the outer take-up structure. The rotating motor 3 is started, and the structure of the rotating motor 3 and the track drives the outlet shaft 7 and the connecting shaft 8 to rotate, thereby making the rotating disk 4 and the bow-shaped cradle 13 rotate synchronously to achieve the stranding of multiple single wires. The output power of the rotating motor 3 can change the torque of the connecting shaft 8, and in combination with the rotational resistance of the wire reel 11, the stranding tension of the single wire can be controlled. The power adjustment of the rotating motor 3 adopts existing frequency conversion technology, and the take-up structure is a common existing technology in this field, which will not be described in detail in this embodiment.

[0019] The movable shield 2 is configured as an arched structure, and at least two openings are provided through the outer side of the movable shield 2; The arched structure design of the movable cover 2 can adapt to the movement trajectory of the internal rotating parts and prevent interference with the cover during rotation. The outer opening not only ensures the routing path of the single line, but also allows the heat generated by the equipment operation to be discharged in time. At the same time, the movable cover 2 can slide along the base 1, which facilitates the maintenance of the internal parts.

[0020] Several bearing seats 16 are disposed on one side edge of the upper end of the base 1. Several bearing seats 16 are arranged in an array on the upper end of the base 1. The outgoing ground shaft 7 is rotatably disposed inside the bearing seat 16. The array distribution design of the bearing housing 16 provides uniform support for the outgoing ground shaft 7, ensuring its stability during rotation.

[0021] The connecting rod 18 extends to the outside of the rotating disk 4. The wire guide plate 5 and the stranded plate 6 are fixedly installed on the extension part of the connecting rod 18. The wire guide plate 5 is installed between the stranded plate 6 and the rotating disk 4. Several wire holes are provided through the surfaces of the rotating disk 4, the wire guide plate 5, and the stranded plate 6. When single-wire twisting is performed, the design of the connecting rod 18 transmits the torque of the rotating disk 4 to the outer component. During wire threading, the multiple single wires are guided in an orderly manner through the threading holes on the surfaces of the rotating disk 4, the wire guide plate 5, and the twisting plate 6 to avoid single wire tangling or crossing during the twisting process. The spacing between the wire guide plate 5 and the twisting plate 6 provides sufficient twisting space for the single wires.

[0022] The wire-passing holes on the surface of the wire-passing plate 5 are designed with a tapered guide hole structure. The inner wall of the tapered wire-passing hole is provided with a spiral micro-groove. The tapered wire-passing holes are divided into several groups and distributed in a ring on the surface of the wire-passing plate 5. The wire-passing guide wheel 19 is distributed at the center of the wire-passing plate 5, forming a concentric path feature. The tapered guide port can guide a single wire to enter the hole precisely, and the spiral micro-groove can discharge debris and gas generated during the threading process. The threading holes distributed in annularly, together with the wire guide rollers 19, allow the single wires at different positions to converge towards the center after being turned by the guide rollers, ensuring that multiple single wires are precisely joined at the twisting point and improving the twisting accuracy.

[0023] A coil shaft 14 is fixedly installed inside the coil 11. Both ends of the coil shaft 14 are rotatably installed inside the bow-shaped cradle 13. A top cone 15 is provided on the outer side of the coil shaft 14. The top cone 15 can tighten the wire spool 11 to prevent it from moving axially during rotation and ensure the stability of single wire release.

[0024] A bearing seat 16 is fixedly installed on the outside of the bow-shaped cradle 13, and a bow belt 9 is fixedly connected to the outside of the bow-shaped cradle 13. The bearing seat 16 is located between the bow-shaped cradle 13 and the bow belt 9, and several bow guide wheels 10 are fixedly installed on the inside of the bow belt 9. The setting of the bow guide wheel 10 can change the routing path of the single line, reduce the direct friction between the single line and the bow belt 9, and reduce tension loss. The roller structure of the bow guide wheel 10 has self-lubricating properties, which can further reduce the coefficient of friction, allowing the torque adjustment mechanism to control the tension of the single line more precisely.

[0025] The working principle of the above embodiment is as follows: During the stranding process, the single metal wire enters from the inlet shaft seat 12, is led out through the wire reel 11, and then passes through the wire holes on the surfaces of the rotating disk 4, the guide plate 5, and the stranding plate 6 in sequence, before connecting to the outer take-up structure. The rotating motor 3 is started, and its power and track structure drive the outlet shaft 7 and the connecting shaft 8 to rotate, so that the rotating disk 4 and the bow-shaped cradle 13 rotate synchronously. The rotating disk 4 transmits torque to the guide plate 5 and the stranding plate 6 through the connecting rod 18. The tapered guide port and spiral micro-groove on the guide plate 5 guide the single wire and remove chips and air. The winding of multiple single wires is achieved through the centripetal convergence path formed by the wire guide wheel 19. During the process, the torque of the connecting shaft 8 is changed by adjusting the output power of the rotary motor 3. Combined with the outer top cone 15 of the wire reel shaft 14 to ensure the stability of the single wire and the inner bow guide wheel 10 of the bow belt 9 to reduce friction, the tension of the single wire winding is precisely controlled. The movable protective cover 2 on the base 1 protects the internal components and ensures the movement and heat dissipation of the single wire through the opening. The bearing seat 16 provides stable support for the wire outlet shaft 7 and the bow-shaped cradle 13, ensuring that the overall winding process is stable and efficient.

[0026] The power adjustment of the rotary motor 3, the use of the winding structure, and the synchronous use of the rotary motor 3 and the track are common existing technologies. The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. They are common knowledge in the field. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
