Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel-cored aluminum stranded wire production technology, and specifically to a steel-cored aluminum stranded wire tension control device. Background Technology
[0002] As the core carrier of power transmission systems, the structural integrity and surface quality of steel-cored aluminum stranded wire directly determine the power grid's conductivity, mechanical load-bearing capacity, and service life.
[0003] Traditional conveying mechanisms often use a single set of conveyor wheels and simple supports to transport wires, and traditional guiding devices often use fixed metal guide blocks, with the stranded wire and the inner wall of the guide block in sliding friction contact.
[0004] There is also the problem that the aluminum layer of steel-cored aluminum stranded wire is relatively soft, and the sliding friction between the traditional guide device and the wire can easily scratch the surface of the aluminum layer, forming scratches of varying depths, which in turn leads to a reduction in the service life of the stranded wire. Utility Model Content
[0005] The purpose of this invention is to provide a tension control device for steel-cored aluminum stranded wire to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A tension control device for steel-cored aluminum stranded wire includes a support plate, a mounting frame fixedly connected to the top of the support plate, a protective shell fixedly connected to the front of the mounting frame, a stranding device provided on the left side of the support plate, and a wire provided inside the protective shell.
[0008] It also includes a conveying mechanism, a tension adjustment mechanism, a lubricating oil application mechanism, and a guide block;
[0009] The conveying mechanism is located inside the protective shell and is used to convey the wire.
[0010] The tension adjustment mechanism is located on the back of the support plate and is used to adjust the tension of the wire during feeding.
[0011] The lubricating oil application mechanism is used to apply a layer of lubricating oil to the surface of the stranded wire.
[0012] The guide block is disposed on the surface of the support plate and is used to guide and position the wire.
[0013] A further improvement of the present invention is that the conveying mechanism includes a first conveying wheel, which is rotatably connected to the left and right sides of the surface of the mounting frame. A tension applying wheel is provided in the middle of the two first conveying wheels, which is located above the first conveying wheel. A second conveying wheel is provided on the left side of the first conveying wheel, which is rotatably connected to the surface of the mounting frame. The wire is movably connected to the surfaces of the first conveying wheel, the tension applying wheel, and the second conveying wheel.
[0014] A further improvement of this utility model is that: the tension adjustment mechanism includes an adjustment block, the adjustment block is disposed on the back of the tension applying wheel, the tension applying wheel is rotatably connected to the front of the adjustment block, a limiting groove and a sliding groove are formed on the surface of the mounting bracket, the limiting groove is disposed on the left and right sides of the sliding groove, the two ends of the adjustment block are slidably connected to the inside of the limiting groove, the middle part of the adjustment block is slidably connected to the inside of the sliding groove, a fixing plate is fixedly connected to the back of the adjustment block, an adjustable cylinder is fixedly connected to the bottom of the fixing plate, and the adjustable cylinder is fixedly connected to the top of the support plate.
[0015] A further improvement of this utility model is that: the lubricating oil application mechanism includes a delivery pump, which is fixedly connected to the top of the protective shell; an oil storage tank is fixedly connected to the bottom of the support plate; an oil dripping pipe is fixedly connected to the output end of the delivery pump; the oil dripping pipe extends through the interior of the mounting frame; the mounting frame is positioned directly above the wire; the input end of the delivery pump extends through the interior of the oil storage tank; an oil replenishment pipe is fixedly connected to the top of the oil storage tank; and a through hole is opened on the surface of the support plate, which is located on the top of the oil storage tank.
[0016] A further improvement of this utility model is that the bottom of the inner wall of the oil storage tank slopes downward from left to right.
[0017] A further improvement of this utility model is that: a guide block is fixedly connected to the surface of the support plate, the wire is inserted into the inside of the guide block, and a rotating column is rotatably connected inside the guide block, the surface of the rotating column being tangent to the surface of the wire.
[0018] The beneficial effects of this utility model are as follows:
[0019] 1. This utility model provides a tension control device for steel-cored aluminum stranded wire. By forming a multi-support conveying path through the conveying mechanism's first and second conveying wheels and the tension application wheel, the wire maintains a stable trajectory during conveying, avoiding wire deviation and twisting caused by single-point force. At the same time, through the design of the rotating column inside the guide block, the rotating column makes tangential contact with the wire surface, transforming traditional sliding friction into rolling friction, which greatly reduces surface wear during wire conveying. In particular, it protects the aluminum layer of the steel-cored aluminum wire from being scratched, avoiding the impact of surface damage on subsequent corrosion resistance and conductivity. Thus, it jointly ensures the integrity of the wire during stress adjustment and conveying, reducing the workpiece scrap rate.
[0020] 2. This utility model provides a tension control device for steel-cored aluminum stranded wire. Through a tension adjustment mechanism, an adjustable cylinder drives an adjusting block to move stably along a limiting groove and a sliding groove, thereby driving the tension applying wheel to adjust its position up and down. This achieves precise control of the tension of the wire conveying. Before the wire enters the stranding device, it eliminates the problem of uneven tension caused by fluctuations in conveying speed and differences in wire diameter, ensuring that each strand of the steel-cored aluminum wire is subjected to consistent force in the subsequent stranding process. This effectively avoids defects such as loose strands, off-center cores, and broken wires in the finished product, significantly improving the structural stability and mechanical strength of the wire and meeting the stringent requirements for wire quality in scenarios such as power transmission.
[0021] 3. This utility model provides a tension control device for steel-cored aluminum stranded wire. Through a lubricating oil application mechanism, the lubricating oil in the oil tank is accurately dripped onto the top of the wire, achieving uniform coating on the surface of the wire. The lubricating oil can reduce the frictional resistance between the wire and the conveying wheel and guide block, which not only protects the conveying components, reduces their wear, and extends the service life of the equipment, but also forms a protective film on the surface of the wire, reducing frictional damage between strands in subsequent wire processing.

[0035] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0036] like Figure 1-6 As shown, this utility model has the following three specific embodiments.
[0037] Example 1
[0038] This utility model provides a tension control device for steel-cored aluminum stranded wire, including a support plate 11, a mounting frame 12 fixedly connected to the top of the support plate 11, a protective shell 13 fixedly connected to the front of the mounting frame 12, a stranding device 14 provided on the left side of the support plate 11, and a wire 15 provided inside the protective shell 13.
[0039] It also includes a conveying mechanism 2, a tension adjustment mechanism 3, a lubricating oil application mechanism 4, and a guide block 51;
[0040] The conveying mechanism 2 is located inside the protective shell 13 and is used to convey the wire.
[0041] The tension adjustment mechanism 3 is located on the back of the support plate 11 and is used to adjust the tension of the wire during wire feeding.
[0042] The lubricating oil application mechanism 4 is used to apply a layer of lubricating oil to the surface of the stranded wire 15;
[0043] The guide block 51 is disposed on the surface of the support plate 11 and is used to guide and position the wire 15.
[0044] In this embodiment, as Figure 1 As shown, the wire 15 is first passed through the guide block 51 for initial guidance and positioning. Then, the wire 15 is fed into the conveying mechanism 2 and then introduced into the stranding device 14. The initial tension is applied to the wire 15 by the tension adjustment mechanism 3 according to the preset tension. Before stranding, the lubricating oil is applied to the surface of the wire by the lubricating oil application mechanism 4. Then, the stranding of the wire is completed by the stranding device 14.
[0045] Example 2
[0046] The difference from Embodiment 1 is that this embodiment discloses a guide block 51, a conveying mechanism 2, and a tension adjusting mechanism 3;
[0047] Preferably, the conveying mechanism 2 includes a first conveyor wheel 21, which is rotatably connected to the left and right sides of the surface of the mounting frame 12. A tension applying wheel 22 is provided in the middle of the two first conveyor wheels 21, which is located above the first conveyor wheel 21. A second conveyor wheel 23 is provided on the left side of the first conveyor wheel 21, which is rotatably connected to the surface of the mounting frame 12. The wire 15 is movably connected to the surfaces of the first conveyor wheel 21, the tension applying wheel 22, and the second conveyor wheel 23.
[0048] The tension adjustment mechanism 3 includes an adjustment block 31, which is located on the back of the tension applying wheel 22. The tension applying wheel 22 is rotatably connected to the front of the adjustment block 31. The surface of the mounting bracket 12 is provided with a limiting groove 32 and a sliding groove 33. The limiting groove 32 is located on the left and right sides of the sliding groove 33. The two ends of the adjustment block 31 are slidably connected to the inside of the limiting groove 32, and the middle part of the adjustment block 31 is slidably connected to the inside of the sliding groove 33. A fixing plate 34 is fixedly connected to the back of the adjustment block 31, and an adjustable cylinder 35 is fixedly connected to the bottom of the fixing plate 34. The adjustable cylinder 35 is fixedly connected to the top of the support plate 11.
[0049] A guide block 51 is fixedly connected to the surface of the support plate 11. The wire 15 is inserted into the inside of the guide block 51. A rotating column 52 is rotatably connected inside the guide block 51. The surface of the rotating column 52 is tangent to the surface of the wire 15.
[0050] In this embodiment, as Figure 2 , 3As shown in Figures 5 and 6, the wire 15 is initially guided and positioned by passing through the guide block 51. The wire 15 is slid across the surface of the rotating column 52, and the frictional resistance and wear of the wire 15 when entering the device are greatly reduced by changing the sliding friction to rolling friction, thus avoiding premature tension loss due to excessive friction. Then, the adjustable cylinder 35 is driven to push the fixed plate 34, which in turn pushes the adjusting block 31 to slide vertically inside the limiting groove 32 and the sliding groove 33. The adjusting block 31 then drives the tension applying wheel 22 to move synchronously. The adjustable cylinder 35 pushes the tension applying wheel 22 to move upward, thereby increasing the wrap angle of the wire and thus increasing the tension of the wire 15. Conversely, the tension applying wheel 22 moves downward to reduce the tension of the wire 15.
[0051] Example 3
[0052] The difference from Embodiment 2 is that this embodiment discloses a lubricating oil application mechanism 4;
[0053] Preferably, the lubricating oil application mechanism 4 includes a delivery pump 41, which is fixedly connected to the top of the protective shell 13. An oil storage tank 42 is fixedly connected to the bottom of the support plate 11. An oil dripping pipe 43 is fixedly connected to the output end of the delivery pump 41. The oil dripping pipe 43 extends into the interior of the mounting bracket 12, which is positioned directly above the wire 15. The input end of the delivery pump 41 extends into the interior of the oil storage tank 42. An oil replenishment pipe 44 is fixedly connected to the top of the oil storage tank 42. A through hole is provided on the surface of the support plate 11, and the through hole on the surface of the support plate 11 is located at the top of the oil storage tank 42.
[0054] The bottom of the inner wall of the oil tank 42 slopes downward from left to right.
[0055] In this embodiment, as Figure 3 and 4 As shown, lubricating oil is drawn from the oil storage tank 42 by starting the delivery pump 41. The lubricating oil drips evenly onto the surface of the wire 15 through the drip pipe 43. Excess lubricating oil drips back into the oil storage tank 42 through the through hole on the surface of the support plate 11. After the tension is applied, the wire 15 is pulled into the center by the twisting device 14 and twisted.
[0056] The working principle of this utility model is as follows:
[0057] First, the wire 15 is fed into the conveying mechanism 2, and then introduced into the stranding device 14. Then, according to the preset tension, the tension adjusting mechanism 3 applies the initial tension to the wire 15. Before stranding, the lubricating oil is applied to the surface of the wire by the lubricating oil application mechanism 4. Then, the stranding of the wire is completed by the stranding device 14.
[0058] By passing the wire 15 through the guide block 51, initial guidance and positioning are achieved. By sliding the wire 15 across the surface of the rotating column 52, the frictional resistance and wear of the wire 15 when entering the device are greatly reduced by changing sliding friction to rolling friction, thus avoiding premature tension loss due to excessive friction. Then, the adjustable cylinder 35 is driven to push the fixed plate 34, which in turn pushes the adjusting block 31 to slide vertically within the limiting groove 32 and the sliding groove 33. The adjusting block 31 then drives the tension applying wheel 22 to move synchronously. The tension applying wheel 22 is pushed upward to increase the wrap angle of the wire and thus increase the tension of the wire 15. Conversely, the tension applying wheel 22 is moved downward to reduce the tension of the wire 15. At the same time, the delivery pump 41 is started to draw lubricating oil from the oil storage tank 42. The lubricating oil drips evenly onto the surface of the wire 15 through the oil drip pipe 43. Excess lubricating oil drips back into the oil storage tank 42 through the through hole on the surface of the support plate 11. After the tension is applied, the stranding device 14 pulls the wire 15 inward and strands it.
[0059] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. The selection and detailed description of these embodiments in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
