Description

Technical Field

[0001] This utility model relates to the field of cable stranding technology, specifically a cantilever cable forming machine. Background Technology

[0002] A stranding machine is a specialized piece of machinery used to strand multiple fine wires or fibers together to produce cables, ropes, and other winding materials. By stranding multiple wires, the stranding machine effectively enhances the tensile strength and fatigue resistance of the resulting cable. The stranding machine mainly consists of a frame, a wire feeding device, a stranding device, a traction device, and a control system. The frame is the foundation of the entire machine, supporting other components, and is typically made of high-strength materials to ensure stability. The wire feeding device smoothly feeds multiple wires into the stranding machine, while the stranding device is the core component. Through the rotation and movement of multiple stranding wheels or stranding shafts, the wires are stranded at specific angles and in a specific manner. The traction device is responsible for controlling the tension and speed of the cable-forming object, ensuring uniform tension during the stranding process and preventing knotting or slackness. For example, a cantilever cable-forming machine disclosed in patent announcement number CN220731241U includes a base. A cable core release device is fixedly installed on the left side of the upper surface of the base, and a cable-forming auger is installed in the center of the upper surface of the base. A traction device is fixedly installed on the right side of the base. The cable core release device includes a support base. A starting motor drives a gear to rotate, which in turn drives a gear to rotate, thereby rotating a rotating rod and a cable core unwinding wheel to release the cable core. A steering wheel turns the cable core so that it enters the interior of a guide disc, which guides the cable core into the cable-forming auger. The cable is internally cabled, and a traction device is activated to transport the cable. This eliminates the need to pull the entire cable core unwinding wheel through the cable and core, thus avoiding excessive traction on the cable and core. However, during the process of introducing the cable to be cabled into the cable-forming auger, the portion of the cable not yet entering the auger lacks support and guidance, and is in a drooping and bent state. This means that the lateral movement force of the cable and the stranded cable during the stranding process is entirely provided by the traction device. At this time, the traction device needs to apply a large force to maintain the movement of the cable. This obstruction not only affects the stranding speed and traction speed of the cable, but may also cause unnecessary friction during the stranding process, increasing wear and even leading to cable breakage. Utility Model Content

[0003] The purpose of this invention is to provide a cantilever cable forming machine in which multiple cables to be stranded are located on a multi-belt feeding structure and separated and guided by a splitter frame. When the multi-belt feeding structure conveys the cables, the rotational power of the multi-belt feeding structure is transmitted to the gear-type cable forming assembly through a pulley transmission structure and a driven shaft. The gear-type cable forming assembly completes the stranding of the cables. The stranded cables are then wound up by a traction device. This allows the traction device to reduce its workload during the tightening and forming of the stranded cables through the multi-belt feeding structure and the splitter frame, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cantilever cable forming machine, comprising a trapezoidal hollow frame and a gear-type cable forming assembly for twisting several cables, which is provided on one outer wall of the trapezoidal hollow frame. A slope plate is installed on the sloped wall of the trapezoidal hollow frame on one side of the gear-type cable forming assembly, and an inclined upward-extending gantry frame is provided on the outer wall of the slope plate near the gear-type cable forming assembly. A cable divider is installed at the top of the trapezoidal hollow frame for separating cables and guiding cables into the gear-type cable forming assembly. The top of the cable divider is fixedly connected to the top wall of the gantry frame. A multi-belt cable feeding structure for conveying several cables is installed inside the trapezoidal hollow frame. A direct drive motor for driving the multi-belt cable feeding structure is installed on one side of the surface of the trapezoidal hollow frame. A driven shaft for driving the gear-type cable forming assembly is rotatably installed on one outer wall of the trapezoidal hollow frame. A pulley transmission structure for maintaining power connection is installed between the driven shaft and the multi-belt cable feeding structure.

[0005] Preferably, the gantry frame includes a U-shaped base fixed to the front and rear outer walls of the trapezoidal hollow frame, two upwardly extending steel columns fixed to the top of the U-shaped base, and an I-beam arm installed at the top of the steel columns.

[0006] Preferably, the distribution frame includes two symmetrical curved horizontal plates fixed to the bottom of the I-beam, a plurality of anti-jump beams integrally formed between the two curved horizontal plates, and a plurality of equally spaced partitions fixed to the bottom of the anti-jump beams, with a channel formed between two adjacent partitions.

[0007] Preferably, the gear-type cable-forming assembly includes an I-shaped cable-forming stranding disc rotatably mounted on one side of the outer wall of the trapezoidal hollow frame, a plurality of wire-passing holes provided inside the I-shaped cable-forming stranding disc, and a rotating shaft rotatably mounted on the outer wall of the trapezoidal hollow frame on one side of the I-shaped cable-forming stranding disc. One end of the rotating shaft is fixed with a driving gear, and a driven gear disc for meshing with the driving gear is fixed on the outer wall of the I-shaped cable-forming stranding disc away from the trapezoidal hollow frame.

[0008] Preferably, one end of the rotating shaft surface is equipped with a bevel gear transmission structure for maintaining power connection with the driven shaft, and the extension line of the central axis of the rotating shaft intersects and is perpendicular to the extension line of the central axis of the bevel gear transmission structure.

[0009] Preferably, the curved cross plate, anti-skid beam, and partition are made of alloy steel components.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This cantilever cable forming machine, through the close cooperation of a trapezoidal hollow frame, a direct drive motor, a multi-belt wire feeding structure, a wire separating frame, a driven shaft, a gear-type cable forming assembly, a pulley transmission structure, and a traction device, enables the cable forming process to be carried out efficiently and stably. The multi-belt wire feeding structure can transport multiple cables simultaneously, which can effectively reduce the swaying and sagging of the cables during the transportation process compared with single wire feeding, and maintain uniform cable tension to ensure stranding quality. The wire separating frame can not only prevent the cables from tangling with each other, but also ensure that each cable is in the correct position and angle when entering the stranding device. This precise guidance can reduce the lateral movement resistance of the cables during the stranding process, thereby improving stranding efficiency and product quality. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-5 This utility model provides an embodiment of a cantilever cable-forming machine, comprising a trapezoidal hollow frame 1 and a gear-type cable-forming assembly 7 for twisting several cables, which is provided on the outer wall of one side of the trapezoidal hollow frame 1. A slope plate 2 is installed on the sloping wall of the trapezoidal hollow frame 1 on one side of the gear-type cable-forming assembly 7, and an inclined upward-extending gantry 3 is provided on the outer wall of the slope plate 2 near the gear-type cable-forming assembly 7. A device for separating cables and guiding cables into the gear-type cable-forming assembly 7 is installed at the top of the trapezoidal hollow frame 1. The cable distribution frame 4 is fixedly connected to the top wall of the gantry frame 3. The trapezoidal hollow frame 1 is equipped with a multi-belt cable feeding structure 5 for conveying several cables. A direct drive motor 6 for driving the multi-belt cable feeding structure 5 is installed on one side of the surface of the trapezoidal hollow frame 1. A driven shaft 8 for driving the gear-type cable assembly 7 is rotatably installed on the outer wall of one side of the trapezoidal hollow frame 1. A pulley transmission structure 9 for maintaining power connection is installed between the driven shaft 8 and the multi-belt cable feeding structure 5.

[0019] The gantry 3 includes a U-shaped seat fixed on the front and rear outer walls of the trapezoidal hollow frame 1, two upwardly extending steel columns fixed at the top of the U-shaped seat, and an I-beam installed at the top of the steel columns; the cable distribution frame 4 includes two symmetrical curved horizontal plates 401 fixed at the bottom of the I-beam, several anti-jump beams 402 integrally formed between the two curved horizontal plates 401, and several equally spaced partitions 403 fixed at the bottom of the anti-jump beams 402, forming a channel between two adjacent partitions 403; the ramp 2 is used to assist the cable in entering the gear-type cable assembly 7.

[0020] A passage for cables is formed between two adjacent partitions 403, and adjacent cables are prevented from jumping or crossing the passage due to the winding action of the gear-type cable assembly 7, so as to avoid tangling of untwisted cables.

[0021] The gear-type cable assembly 7 includes an I-shaped cable stranding disc 701 rotatably mounted on one side of the outer wall of the trapezoidal hollow frame 1, a plurality of wire-passing holes 702 provided inside the I-shaped cable stranding disc 701, and a rotating shaft 703 rotatably mounted on the outer wall of the trapezoidal hollow frame 1 on one side of the I-shaped cable stranding disc 701. One end of the surface of the rotating shaft 703 is fixed with a driving gear 705, and a driven gear disc 704 for meshing with the driving gear 705 is fixed on the outer wall of the I-shaped cable stranding disc 701 on the side away from the trapezoidal hollow frame 1.

[0022] One end of the surface of the rotating shaft 703 is equipped with a bevel gear transmission structure 706 for maintaining power connection with the driven shaft 8. The extended line of the central axis of the rotating shaft 703 intersects and is perpendicular to the extended line of the central axis of the bevel gear transmission structure 706. The curved cross plate 401, the anti-jump beam 402, and the partition plate 403 are made of alloy steel components.

[0023] During the movement of the cable, the rotational power of the multi-belt cable conveying structure 5 is transmitted to the rotating shaft 703 through the pulley transmission structure 9, the driven shaft 8, and the bevel gear transmission structure 706. The rotating shaft 703 then drives the I-shaped cable stranding disc 701 to rotate using the driving gear 705 and the driven gear disc 704. At this time, the I-shaped cable stranding disc 701 rotates on its own axis, and several cable passage holes 702 rotate around the central axis of the I-shaped cable stranding disc 701, so that the cable passing through the cable passage holes 702 can be stranded. The gear-type cable assembly 7 and the multi-belt cable conveying structure 5 share a direct drive motor 6 as the driving power source. The pulley transmission structure 9 distributes the power evenly, reducing the operating energy consumption of the equipment while ensuring the stranding speed.

[0024] In this embodiment, the operator first guides the multiple cables to be twisted into a cable through the distribution frame 4 to the multi-belt cable conveyor structure 5. The distribution frame 4 ensures that each cable maintains an appropriate distance during the conveying process of the multi-belt cable conveyor structure 5, preventing mutual interference between the cables. This effectively guides the cables into the gear-type cable assembly 7, ensuring smooth flow of the cables during the twisting process. The operator then passes one end of the cable through the gear-type cable assembly 7 and manually twists the multiple cables together initially. The twisted cable is then connected to the traction device, which pulls and winds the cable. During this process, the operator starts the direct drive motor 6. The operation involves the simultaneous transport of multiple cables by a multi-belt conveyor structure 5. The synchronous operation of each belt in the multi-belt conveyor structure 5 ensures the stability of the cables during transport, preventing knotting and tangling. During this process, the twisted and unformed cables are also wound by the traction device. The rotational power of the multi-belt conveyor structure 5 is transmitted to the gear-type cable assembly 7 through the pulley transmission structure 9 and the driven shaft 8. The gear-type cable assembly 7 twists multiple cables at a certain angle and tension to form a twisted cable. The traction device on one side of the gear-type cable assembly 7 controls the tension and speed of the cables, ensuring that the twisted cables can be neatly wound into a roll.
