Description

Technical Field

[0001] This utility model belongs to the field of stranded wire production technology, specifically relating to an aluminum alloy cable stranding device. Background Technology

[0002] A stranding machine is a key piece of equipment widely used in industries such as wire and cable, communications, power, and construction. It is primarily used to strand multiple metal wires or fiber filaments into cables or ropes with specific structures and properties. Its working principle is based on rotation and tension control, achieving uniform stranding of the wires through precise mechanical operation, thereby improving product quality and production efficiency.

[0003] Aluminum alloy cable is a power transmission cable that uses aluminum alloy as the conductor material. It has advantages such as being lightweight, corrosion-resistant, and having good conductivity. However, in the current stranding production equipment for aluminum alloy cables, due to the high strength and poor plasticity of aluminum alloy cables, the single-filament bundles of cables are prone to bending. During the cable bonding process, it is difficult to tightly bond the cable bundles together, resulting in poor stranding quality of the cable.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide an aluminum alloy cable stranding device.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide an aluminum alloy cable stranding device that can solve the problem of poor stranding quality of aluminum alloy cables in the prior art.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides an aluminum alloy cable stranding device, including: a main frame, a wire outlet device, and a wire straightening device;

[0008] A fixed shaft is fixed on the main frame, a turntable is rotatably mounted on the fixed shaft, a tripod is fixed on the turntable, a plurality of second gears are rotatably mounted on the turntable, and a first gear is fixed at one end of the fixed shaft near the tripod, and the first gear meshes with the second gears.

[0009] The cable outlet device is mounted on the second gear. The cable outlet device includes a fixed frame, a fixed seat is fixed on the fixed frame, a sliding rod is fixed on the fixed seat, a slider is slidably mounted on the sliding rod, a reciprocating gearbox and a belt gear are respectively mounted on both ends of the fixed seat, a belt is installed between the reciprocating gearbox and the belt gear, and a drive shaft is inserted into the fixed frame.

[0010] The wire straightening device is mounted on a slider. The wire straightening device includes a base, which is rotatably mounted on the slider. An infeed roller and multiple guide rollers are mounted on the base. A pair of first mounting plates and a second mounting plate are fixed on the base. A row of first straightening rollers is mounted on each of the first and second mounting plates. Multiple grooves are cut into each of the first and second mounting plates. A moving block is slidably arranged in each of the multiple grooves. A second straightening roller is fixed on each of the moving blocks.

[0011] In one or more embodiments of this utility model, a winding device and a drive motor are installed on the main frame. The winding device is used to collect the twisted cable. A first transmission belt is installed between the turntable and the drive motor. The drive motor drives the turntable to rotate through the first transmission belt.

[0012] In one or more embodiments of this utility model, the tripod is equipped with a number of wire guide devices that are the same as the number of second gears. A wire bundle tube is fixed at the end of the tripod away from the turntable. The wire bundle that comes out from the wire outlet device is guided by the wire guide device and then enters the wire bundle tube for twisting. After the twisting is completed, the wire bundle is collected on the winding device.

[0013] In one or more embodiments of this utility model, the reciprocating gearbox is characterized by having a third gear installed on it. The third gear is used to transmit kinetic energy to the reciprocating gearbox, causing the reciprocating gearbox to drive the belt to reciprocate. A second transmission belt is installed between the third gear and the transmission shaft, and the transmission shaft drives the third gear to rotate through the second transmission belt.

[0014] In one or more embodiments of this utility model, a control plate is fixed to the bottom end of the slider, and the control plate is fixedly connected to the belt. The belt drives the slider to slide back and forth on the slide rod through the control plate.

[0015] In one or more embodiments of this utility model, the slider is equipped with multiple pairs of pulleys, and the fixed base is equipped with a fixed plate. A pair of pulleys slides on both sides of the fixed plate. By having multiple pairs of pulleys slide on both sides of the fixed plate, the slider is assisted to slide on the slide rod, and the slider is prevented from rotating on the slide rod.

[0016] In one or more embodiments of this utility model, the drive shaft is provided with a wire feeding reel installed in the fixed frame. The wire feeding reel is used to prevent wire from getting tangled, and the tangled wire is led out from the wire feeding reel.

[0017] In one or more embodiments of this utility model, a first threaded sleeve is fixed on the first mounting plate and the second mounting plate at the slide groove. A first control rod is threadedly connected to the first threaded sleeve. Since the first threaded sleeve and the first control rod are threadedly connected, when the first control rod is rotated, the first control rod moves back and forth. One end of the first control rod located in the slide groove is rotatably connected to the moving block. The back and forth movement of the first control rod drives the moving block to move back and forth. The moving block drives the second straightening roller to move closer to or away from the first straightening roller. Depending on the thickness of different strands, the thickness of the strands can be adapted by adjusting the distance between the first straightening roller and the second straightening roller.

[0018] In one or more embodiments of this utility model, a rotating component is rotatably provided at the bottom of the base, and a second control rod is rotatably provided on the rotating component. By moving the second control rod up and down, the base is rotated on the slider to adjust the tilt angle of the base, thereby adjusting the wire exit angle.

[0019] In one or more embodiments of this utility model, a fixing plate is fixed on the slider, and a pair of second threaded sleeves are threadedly connected to the second control rod. The pair of second threaded sleeves are respectively disposed on both sides of the fixing plate.

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0034] like Figures 1-9 As shown, an aluminum alloy cable stranding device according to one embodiment of the present invention includes: a main frame 1, a wire outlet device 2, and a wire straightening device 3.

[0035] like Figures 1-3 As shown, a fixed shaft 102 is fixed on the main frame 1 for rotatably mounting the turntable 103 and fixing the first gear 106. The turntable 103 is rotatably mounted on the fixed shaft 102, a tripod 108 is fixed on the turntable 103, and multiple second gears 107 are rotatably mounted on the turntable 103. The turntable 103 drives the tripod 108 and the second gears 107 to rotate, thereby twisting the wire harness. The second gears 107 are used to mount the wire exit device 2 and drive the wire exit device 2 to rotate. The first gear 106 is fixed to one end of the fixed shaft 102 near the tripod 108. The first gear 106 meshes with the second gears 107. When the turntable 103 drives the second gear 107 to rotate, the first gear 106 simultaneously drives the second gear 107 to rotate, and the second gear 107 drives the wire exit device 2 to rotate, thereby counteracting the torque exerted on the wire harness by the turntable 103 driving the second gear 107 to rotate.

[0036] like Figures 1-3 As shown, a winding device 101 and a drive motor 104 are installed on the main frame 1. The winding device 101 is used to collect the twisted cable. A first transmission belt 105 is installed between the turntable 103 and the drive motor 104. The drive motor 104 drives the turntable 103 to rotate through the first transmission belt 105. A wire guide device 109 with the same number as the second gear 107 is installed on the tripod 108. A wire bundle tube 110 is fixed at the end of the tripod 108 away from the turntable 103. The wire bundle coming out from the wire outlet device 2 is guided by the wire guide device 109, then passes through the wire bundle tube 110 for twisting, and then is collected on the winding device 101 after twisting is completed.

[0037] like Figure 1 and 4As shown, the wire exit device 2 is mounted on the second gear 107. The wire exit device 2 includes a fixed frame 201, a fixed base 203 fixed on the fixed frame 201, a slide rod 204 fixed on the fixed base 203, and a slider 205 slidably mounted on the slide rod 204. Since the wire harness is wound in a figure-eight shape on the wire release reel 214, the slider 205 drives the wire straightening device 3 to slide back and forth on the slide rod 204 to adapt to the wire exit angle. A reciprocating gearbox 207 and a belt gear 210 are respectively installed at both ends of the fixed base 203. The reciprocating gearbox 207 is used to convert the unidirectional rotational kinetic energy of the third gear 208 into reciprocating rotational kinetic energy, thereby driving the belt 206 to reciprocate. The belt gear 210 is used to assist the belt 206 in rotating. A belt 206 is installed between the reciprocating gearbox 207 and the belt gear 210. The belt 206 drives the slider 205 to slide back and forth on the slide rod 204. A drive shaft 202 is inserted into the fixed frame 201. The drive shaft 202 is used to connect an external drive device to drive it to rotate, thereby driving the pay-off reel 214 and the third gear 208 to rotate.

[0038] like Figures 4-5 As shown, a third gear 208 is installed on the reciprocating gearbox 207. The third gear 208 is used to transmit kinetic energy to the reciprocating gearbox 207, causing the reciprocating gearbox 207 to drive the belt 206 to reciprocate. A second transmission belt 209 is installed between the third gear 208 and the transmission shaft 202. The transmission shaft 202 drives the third gear 208 to rotate through the second transmission belt 209. A control plate 211 is fixed to the bottom of the slider 205. The control plate 211 is fixedly connected to the belt 206. The belt 206 drives the slider 205 to slide back and forth on the slide rod 204 through the control plate 211.

[0039] like Figures 4-5 As shown, multiple pairs of pulleys 213 are installed on the slider 205, and a fixed plate 212 is installed on the fixed base 203. A pair of pulleys 213 slide on both sides of the fixed plate 212 respectively. The multiple pairs of pulleys 213 sliding on both sides of the fixed plate 212 assist the slider 205 in sliding on the slide rod 204, and also prevent the slider 205 from rotating on the slide rod 204. The drive shaft 202 is located inside the fixed frame 201 and has a wire feeding reel 214 installed. The wire feeding reel 214 is used to hold the stranded wire, and the stranded wire is led out from the wire feeding reel 214.

[0040] like Figure 4 and 6As shown, the wire straightening device 3 is mounted on the slider 205. The wire straightening device 3 includes a base 301, which is rotatably mounted on the slider 205. An infeed roller 302 and multiple guide rollers 303 are mounted on the base 301. The infeed roller 302 is used for the wire harness to enter, and the multiple guide rollers 303 are used to correct the direction of movement of the wire harness. A pair of first mounting plates 304 and second mounting plates 315 are fixed on the base 301. The first straightening roller 305 and the second straightening roller 306 mounted on the first mounting plate 304 are used to provide lateral straightening of the wire harness, and the first straightening roller 305 and the second straightening roller 306 mounted on the second mounting plate 315 are used to provide longitudinal straightening of the wire harness.

[0041] like Figures 6-9 As shown, a row of first straightening rollers 305 are installed on both the first mounting plate 304 and the second mounting plate 315. Multiple grooves 314 are cut into both the first mounting plate 304 and the second mounting plate 315. Movable blocks 307 are slidably arranged in each of the multiple grooves 314. Second straightening rollers 306 are fixed on each of the movable blocks 307. The first straightening rollers 305 and the second straightening rollers 306 are used to straighten the wire harness. At the same time, the second straightening rollers 306 slide in the wire feeding reel 214 through the movable blocks 307. The thickness of the wire harness that can pass between the first straightening rollers 305 and the second straightening rollers 306 can be adjusted according to the different thicknesses of the wire harnesses.

[0042] like Figures 6-9 As shown, a first threaded sleeve 309 is fixed on the first mounting plate 304 and the second mounting plate 315 at the slide groove 314. A first control rod 308 is threadedly connected to the first threaded sleeve 309. Since the first threaded sleeve 309 and the first control rod 308 are threadedly connected, when the first control rod 308 is rotated, the first control rod 308 moves back and forth. One end of the first control rod 308 located in the slide groove 314 is rotatably connected to the moving block 307. The back and forth movement of the first control rod 308 drives the moving block 307 to move back and forth. The moving block 307 drives the second straightening roller 306 to move closer to or away from the first straightening roller 305. Depending on the thickness of the stranded wire, the distance between the first straightening roller 305 and the second straightening roller 306 can be adjusted to adapt to the thickness of the stranded wire. The base 301 has a rotating component 311 rotatably mounted on its bottom. A second control lever 312 is rotatably mounted on the rotating component 311. By moving the second control lever 312 up and down, the base 301 is rotated on the slider 205 to adjust the tilt angle of the base 301, thereby adjusting the wire exit angle.

[0043] like Figures 6-9As shown, a fixing plate 310 is fixed on the slider 205, and a pair of second threaded sleeves 313 are threadedly connected to the second control rod 312. The pair of second threaded sleeves 313 are respectively located on both sides of the fixing plate 310. On the one hand, the pair of second threaded sleeves 313 clamp each other on the fixing plate 310, thereby fixing the second control rod 312 and thus fixing the base 301. On the other hand, by rotating the pair of second threaded sleeves 313, the position of the pair of second threaded sleeves 313 on the second control rod 312 is adjusted, thereby adjusting the length of the second control rod 312 on the fixing plate 310 and changing different tilt angles of the base 301.

[0044] Working principle: First, the wire harness on the chute 314 is moved out, passes over the infeed roller 302, passes between a pair of guide rollers 303, and then passes between the first straightening roller 305 and the second straightening roller 306 on the first mounting plate 304 and the second mounting plate 315, and then passes between two pairs of guide rollers 303. At this time, the distance between the first straightening roller 305 and the second straightening roller 306 can be adjusted according to the thickness of the wire harness. All the moved-out wire harnesses pass over the lead-in device 109 corresponding to the second gear 107, and then pass through the wire harness tube 110. The end of the wire harness is wound on the winding device 101. Then the drive motor 104 is started. The drive motor 104 drives the turntable 103 to rotate through the first transmission belt 105. The turntable 103 drives the second gear 107 and the tripod 108 to rotate, twisting the wire harness.

[0045] Simultaneously, the drive device connected to the drive shaft 202 is activated, and the drive shaft 202 drives the pay-off reel 214 to rotate, thus feeding the wire. The drive shaft 202 drives the third gear 208 to rotate synchronously through the second drive belt 209. The third gear 208 transmits rotational kinetic energy to the reciprocating gearbox 207. The reciprocating gearbox 207 drives the belt 206 to reciprocate. The belt 206 drives the slider 205 to reciprocate on the slide bar 204 through the control board 211. The slider 205 drives the wire straightening device 3 to reciprocate to adapt to the wire feeding position on the pay-off reel 214.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
