Description

Technical Field

[0001] This utility model belongs to the field of stranding technology, and in particular to a device for stranding wires and cables. Background Technology

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize electromagnetic energy conversion. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, a cable refers to an insulated cable, which can be defined as an assembly consisting of one or more insulated cores, and their respective possible sheaths, overall protective layers, and outer protective layers. Cables may also have additional uninsulated conductors, and are composed of multiple stranded wires. During the wire and cable manufacturing process, stranding devices are used to strand the raw materials. However, traditional stranding devices do not properly tighten the stranded wires and cables, which affects the overall stranding effect.

[0003] A search revealed a Chinese patent document (authorization announcement number CN117038209B) entitled "A cage-type stranding device for wires and cables with a straightening structure," comprising a base plate, with a motor mounted on the outer left side of the base plate, and a sleeve rod integrally mounted on the output end of the motor. This cage-type stranding device for wires and cables with a straightening structure allows for adjustment of the tension of the conveyed wires and cables as needed, preventing wire skipping. It also allows adjustment of the conductor cutting angle, and straightens the stranded wires and cables using pressure rollers. The spacing of the pressure rollers can be adjusted as needed, and a limit mechanism is provided on the pressure rollers to prevent the stranded wires from shifting during straightening and pressing, thus affecting the processing quality. While the stranding device in the aforementioned patent can straighten wires and cables, it does not provide proper clamping of the stranded wires and cables, which affects the overall stranding effect. Utility Model Content

[0004] The purpose of this utility model is to provide a wire and cable stranding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire and cable stranding device, comprising:

[0006] Workbench;

[0007] An assembly circular plate is rotatably connected to the worktable via bearings. A transmission rod is fixedly connected to the side of the assembly circular plate, and a stranded circular plate is connected to the side of the transmission rod.

[0008] An assembly tube is positioned above the workbench. The inner cavity of the assembly tube contains four movable plates. Multiple clamping wheels for clamping electrical wires and cables are connected to the sides of the movable plates. Four adjusting electric push rods, corresponding to the positions of the movable plates, are embedded in the outer circumference of the assembly tube. The moving parts of the adjusting electric push rods are connected to limit plates. A hollow plate connected to the movable plates is sleeved around the outer circumference of the limit plates. A pressure sensor is mounted on the side of the limit plates, and a spring connects the measuring part of the pressure sensor to the movable plates.

[0009] As a preferred embodiment, the two clamping wheels facing different directions are staggered, and the assembly tube is connected and fixed to the worktable through multiple auxiliary rods.

[0010] As a preferred embodiment, the side of the assembly circular plate is equipped with multiple fixing components for fixing the wire and cable raw materials, and the side of the stranded circular plate is provided with multiple circular channels through which the power supply cable raw materials pass.

[0011] As a preferred embodiment, a hollow gear is also connected to the side of the assembly circular plate, and the hollow gear is meshed with a drive gear. A speed-regulating motor that provides power to the drive gear is installed at the top of the worktable.

[0012] As a preferred embodiment, an auxiliary ring is provided on one side of the assembly tube, and the auxiliary ring is connected and fixed to the assembly tube by multiple diagonal connecting rods.

[0013] As a preferred embodiment, the inner wall of the auxiliary ring is rotatably connected to a wire-concentrating ring via a bearing.

[0014] As a preferred embodiment, a vertical electric actuator is installed at the top of the worktable, and a guide wheel corresponding to the position of the assembled round tube is installed at the top of the moving part of the vertical electric actuator.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This wire and cable stranding device benefits from the design of the assembled round tube and the clamping wheel. By controlling and adjusting the electric push rod, the distance between the four movable plates is changed, so that the clamping wheel clamps and fixes the stranded wire and cable, ensuring that the wire and cable will not rotate or move randomly during the stranding operation, thus not affecting the stranding effect. Moreover, the clamping effect can be understood from the data expressed by the pressure sensor. If no movement is required, the extension of the electric push rod is continuously controlled to prevent the spring from deforming, thus ensuring the clamping effect.

[0017] This wire and cable stranding device benefits from the wire gathering ring and the conductor wheel. The wire gathering ring can perform wire gathering operations, the rotatable design of the wire gathering ring will not affect the stranding operation, and the limiting of the conductor wheel can prevent the stranded wire and cable from being transported normally in the future.

[0018] This wire and cable stranding device can tighten and transport wires to meet different usage needs. Attached Figure Description

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0029] The connection method can adopt existing methods such as bonding, welding, and bolting, depending on the actual needs. Techniques, methods and equipment known to those skilled in the art may not be discussed in detail. However, where appropriate, the techniques, methods and equipment should be regarded as part of the specification. The proportions of the components in the drawings are for reference only and can be adjusted to a certain extent according to the actual use.

[0030] Please see Figures 1 to 4 As shown, a wire and cable stranding device, in this embodiment, includes:

[0031] Workbench 1;

[0032] Assembly round plate 22 is rotatably connected to workbench 1 via bearing. Transmission rod 2 is fixedly connected to the side of assembly round plate 22, and stranded round plate 3 is connected to the side of transmission rod 2.

[0033] An assembly tube 4 is positioned above the workbench 1. The central axis of the assembly tube 4 coincides with the central axis of the transmission rod 2 to ensure that the wires and cables do not slip. The inner cavity of the assembly tube 4 is equipped with four movable plates 5. Multiple clamping wheels 6 are connected to the sides of the movable plates 5 to clamp the wires and cables. The material of the clamping wheels 6 ensures that the wires and cables will not be damaged and has a certain amount of friction to prevent the wires and cables from moving easily. Four adjusting electric push rods 7 are embedded in the outer periphery of the assembly tube 4, corresponding to the positions of the movable plates 5. The moving part of the adjusting electric push rod 7 is connected to a limit plate 8. A hollow plate 9 connected to the movable plate 5 is sleeved on the outer periphery of the limit plate 8. A pressure sensor 10 is installed on the side of the limit plate 8. A spring 11 is connected between the measuring part of the pressure sensor 10 and the movable plate 5. During the twisting process, the adjusting electric push rods 7 are extended. The clamping effect can be understood from the data expressed by the pressure sensor 10. The specific required value can be determined based on past experience.

[0034] The two clamping wheels 6 facing different directions are staggered, that is, the positions of the two parallel movable plates 5 are corresponding, but the clamping wheels 6 of the two adjacent movable plates 5 are staggered. This design can increase the size range of wires and cables that can be adapted, and can also play a role in fixing and correcting. The assembly round tube 4 is connected and fixed to the worktable 1 through multiple auxiliary rods 12.

[0035] To meet usage requirements, the side of the assembly round plate 22 is equipped with multiple fixing components 13 for fixing the wire and cable raw materials. The fixing components 13 are quick-installation fixing structures, and their appearance and dimensions are not based on the illustrations. The side of the stranded round plate 3 has multiple circular channels through which the power supply cable raw materials pass. The side of the assembly round plate 22 is also connected to a hollow gear 14, which meshes with a drive gear 15. The top of the workbench 1 is equipped with a speed-regulating motor 16 that provides power to the drive gear 15. During the pulling process, the speed-regulating motor 16 is turned on, which drives the drive gear 15 to rotate, drives the hollow gear 14 to rotate, and then drives the assembly round plate 22 to rotate, so that the pulled wire and cable raw materials are stranded.

[0036] For material gathering and guidance, an auxiliary ring 17 is provided on one side of the assembly tube 4. The auxiliary ring 17 is connected and fixed to the assembly tube 4 through multiple inclined connecting rods 18. The inner wall of the auxiliary ring 17 is rotatably connected to a wire gathering ring 19 through a bearing.

[0037] For guidance, a vertical electric actuator 20 is installed at the top of the workbench 1. The top of the moving part of the vertical electric actuator 20 is equipped with a guide wheel 21 corresponding to the position of the assembly tube 4. A power device with winding and pulling capability is also provided on one side of the workbench 1. The workbench 1 is also equipped with other auxiliary equipment to meet the usage needs. The wire and cable raw materials are placed in the fixed component 13, and the wire and cable raw materials are passed through the circular channel of the stranded circular plate 3, through the wire gathering ring 19 and the assembly tube 4, around the guide wheel 21, and pulled by the power device.

[0038] It should be noted that many data points in this application require adjustment based on past experience and are not suitable for initial use. After multiple uses, based on experience, the various instruments and structures can be linked and controlled using a controller to achieve satisfactory wire stranding.

[0039] The pressure sensor 10, speed-regulating motor 16, and vertical electric actuator 20 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this utility model.

[0040] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0041] Working principle

[0042] The wire and cable stranding device places the wire and cable raw material into the fixed component 13, passes the wire and cable raw material through the circular channel of the stranding plate 3, passes through the wire gathering ring 19 and the assembly round tube 4, goes around the conductor wheel 21, and is pulled by a power device.

[0043] During the pulling process, the speed-regulating motor 16 is turned on, which drives the drive gear 15 to rotate, drives the hollow gear 14 to rotate, and then drives the assembly disc 22 to rotate, so that the pulled wire and cable material is twisted. During the twisting process, the electric push rod 7 is controlled to extend, and the clamping effect is understood from the data expression of the pressure sensor 10.
