Description

Technical Field

[0001] This utility model relates to the field of stranded wire technology, and in particular to a multi-strand stranded wire device. Background Technology

[0002] In the field of large-scale wire and cable production, the efficiency and stability of the multi-strand stranding process directly determine production capacity and product quality. With the surge in demand for cables from the electronics and power industries (such as new energy cables and data center cabling), traditional single-strand stranding devices can no longer meet the production requirements of "multiple batches and high efficiency".

[0003] Existing stranding devices suffer from problems such as unstable clamping, difficulty in adjustment, and low operational safety when pre-fixing multi-strand wires. This paper proposes a multi-strand stranding device that is structurally stable, highly adjustable, effectively prevents wire slippage, and facilitates rapid positioning.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: when workers need to hold multiple strands of wire to twist the wire, the grip strength of the hand decreases after holding it for a long time, making it difficult to hold multiple strands of wire to twist the wire at the same time, thus causing problems such as difficulty in normal use or injury to the worker's hand. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of reducing the grip strength of the hand when held for a long time, making it difficult to hold multiple strands of wire at the same time for twisting, which makes it difficult to use normally or causes injury to the hands of the workers. To this end, we propose a multi-strand twisting device.

[0006] To achieve the above objectives, this application adopts the following technical solution: a multi-strand stranding device, including a stranding machine, three stranding clamps installed inside the stranding machine, a wire fixing device provided on the surface of the stranding machine, the wire fixing device including a support frame, the support frame being fixedly connected to the surface of the stranding machine, two sliding frames being slidably connected to the surface of the support frame, a support plate being fixedly connected to one side of the two sliding frames that are close to each other, a clamping frame being fixedly connected to the surface of the support plate, a drive rod being threaded into the clamping frame, and a clamping plate being rotatably connected to one end of the drive rod.

[0007] Preferably, an anti-slip pad is fixedly connected to one side of the clamping plate, and the surface of the anti-slip pad is provided with a plurality of anti-slip protrusions.

[0008] Preferably, two positioning rods are fixedly connected to the surface of the clamping plate, and the arc surface of the positioning rods is slidably connected to the clamping frame.

[0009] Preferably, two rubber rings are fixedly connected to the surface of the clamping frame, and the rubber rings are slidably connected to the arc surface of the positioning rod.

[0010] Preferably, an adjustment device is provided on the side of the two sliding frames that are far apart from each other. The adjustment device includes two fixed rods, which are respectively fixedly connected to the side of the two sliding frames that are far apart from each other. An operating plate is slidably connected to the arc surface of the fixed rods. A plug rod is fixedly connected to one side of the operating plate. Slots are provided on both sides of the support frame.

[0011] Preferably, one end of the fixing rod is fixedly connected to a limiting plate, and the size of the insertion rod is adapted to the size of the slot.

[0012] Preferably, the arc surface of the fixing rod is fitted with a first spring, and the two ends of the first spring are fixedly connected to the operating plate and the sliding frame, respectively.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. In this utility model, by setting up a wire fixing device, the multi-strand wires to be twisted are fixed and clamped, which avoids the situation where the grip strength of the hand decreases when the worker needs to hold the multi-strand wires for a long time, making it difficult to hold the multi-strand wires for twisting at the same time, thus causing difficulties in normal use or injury to the worker's hand, thereby improving the safety of the device.

[0015] 2. In this utility model, by setting an adjustment device, the distance between the multi-strand wires and the stranding clamp is adjusted, which avoids the situation where the wires are too long or too short, making it difficult to clamp and fix them, thus making it difficult to perform the stranding work, and improves the applicability of the device.

Detailed Implementation

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Reference Figure 1 As shown, this utility model provides a technical solution: a multi-strand stranding device, including a stranding machine 1, three stranding clamps 2 installed inside the stranding machine 1, and a wire fixing device 3 on the surface of the stranding machine 1. By setting the wire fixing device 3, the multi-strand wires to be stranded are fixed and clamped, avoiding the situation where the operator's grip strength decreases due to prolonged holding of the multi-strand wires, making it difficult to hold multiple wires simultaneously for stranding, thus causing difficulty in normal use or injury to the operator's hands, thereby improving the safety of the device. An adjustment device 4 is provided on the side of the two sliding frames 32 that are far apart from each other. By setting the adjustment device 4, the distance between the multi-strand wires and the stranding clamps 2 is adjusted, avoiding the situation where the length of the wires is too long or too short, making it difficult to clamp and fix, thus making it difficult to perform the stranding work, thereby improving the applicability of the device.

[0025] The following section will describe in detail the specific setup and function of its wire fixing device 3 and adjusting device 4.

[0026] Reference Figure 2 , Figure 3 and Figure 5As shown, in this embodiment: the wire fixing device 3 includes a support frame 31, which is fixedly connected to the surface of the stranding machine 1. Two sliding frames 32 are slidably connected to the surface of the support frame 31. A support plate 33 is fixedly connected to one side of the two sliding frames 32 that are close to each other. A clamping frame 34 is fixedly connected to the surface of the support plate 33. A drive rod 35 is threaded into the clamping frame 34. One end of the drive rod 35 is rotatably connected to a clamping plate 36. An anti-slip pad 37 is fixedly connected to one side of the clamping plate 36. The surface of the anti-slip pad 37 is provided with several anti-slip protrusions, which increases the clamping capacity of multi-strand wires. To enhance stability during stranding, the clamping plate 36 is fixedly connected to two positioning rods 38. The arc surface of the positioning rods 38 is slidably connected to the clamping frame 34, which restricts the clamping plate 36 from rotating with the drive rod 35, thus providing stable guidance for the clamping plate 36. The clamping frame 34 is fixedly connected to two rubber rings 39, which are slidably connected to the arc surface of the positioning rods 38. The elasticity of the rubber rings 39 wraps around the arc surface of the positioning rods 38, thereby reducing the impact of external shaking on the clamping plate 36 and providing a damping effect.

[0027] Reference Figure 4 and Figure 5 As shown, specifically, the adjusting device 4 includes two fixed rods 41, which are fixedly connected to the opposite sides of the two sliding frames 32. An operating plate 42 is slidably connected to the arc surface of the fixed rod 41, and an insert rod 43 is fixedly connected to one side of the operating plate 42. Slots 44 are provided on both sides of the support frame 31. A limit plate 45 is fixedly connected to one end of the fixed rod 41. The size of the insert rod 43 is adapted to the size of the slot 44, which achieves the effect of limiting the maximum sliding distance of the operating plate 42 on the arc surface of the fixed rod 41. This avoids the situation where the operating plate 42 detaches from the arc surface of the fixed rod 41 due to excessive pulling force when the operator pulls the operating plate 42. A first spring 46 is sleeved on the arc surface of the fixed rod 41. The two ends of the first spring 46 are fixedly connected to the operating plate 42 and the sliding frame 32, respectively. The first spring 46 achieves the effect of automatically bringing the insert rod 43 back, which improves the stability of the insert rod 43 when limiting the sliding frame 32.

[0028] Working principle: In use, multiple strands of wire are placed into the clamping frame 34 (fixed to the support plate 33, which is connected to two sliding frames 32). The multiple strands of wire are aligned with multiple stranding clamps 2. At this time, the drive rod 35 inside the clamping frame 34 is rotated, pushing the clamping plate 36 closer to the wire until the anti-slip pad 37 (with anti-slip protrusions on the surface) on one side of the clamping plate 36 is in close contact with the wire. The anti-slip protrusions increase friction and prevent the wire from slipping during stranding. The two positioning rods 38 on the surface of the clamping plate 36 slide along the clamping frame 34, limiting the clamping plate 36 from rotating with the drive rod 35 and providing stable guidance. The rubber ring 39 on the surface of the clamping frame 34 wraps around the positioning rods 38 with elasticity, reducing the impact of external shaking on the clamping plate 36 and playing a damping role, further ensuring clamping stability. After clamping is completed, the stranding machine 1 is started. The stranding machine 1 drives multiple stranding clamps 2 to clamp and rotate the multiple strands of wire.

[0029] When the clamping position needs to be adjusted, pull the operating plate 42 to overcome the elastic force of the first spring 46 (which is connected to the operating plate 42 and the sliding frame 32 at both ends respectively), so that it slides along the fixed rod 41 (fixed to the sliding frame 32), driving the insertion rod 43 to be pulled out from the slot 44 of the support frame 31, thus releasing the limitation on the sliding frame 32; then push the sliding frame 32 to slide along the surface of the support frame 31, driving the clamping frame 34 to move to the target position, release the operating plate 42, and the first spring 46 automatically resets and pushes the operating plate 42, so that the insertion rod 43 is reinserted into the corresponding slot 44, thus completing the fixation of the sliding frame 32 and the clamping frame 34. The limiting plate 45 at one end of the fixed rod 41 can prevent the operating plate 42 from being pulled off the fixed rod 41 due to excessive force, thus ensuring operational safety.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
