Description

Technical Field

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

[0002] A cable stranding machine is a key piece of equipment used to strand multiple single wires into cable cores or cable cores according to certain rules. Its core function is to use mechanical transmission to make the single wires spirally wind around the central axis to form a stranded wire group with stable structure and reliable performance.

[0003] Chinese Patent Publication No. CN221861343U discloses a cable stranding machine head, including a connecting plate. A support base is fixedly connected to the connecting plate, and a rotating disk is rotatably connected to the support base via bearings. The rotating disk rotates via a rotating mechanism. A movable seat is provided on the connecting plate via a moving mechanism, and a stranding sleeve is fixedly connected to the movable seat. The stranding sleeve is coaxially arranged with the rotating disk. This utility model adjusts the precision of stranding to produce cables with different tightnesses, ensuring the applicability of the device.

[0004] In the aforementioned prior art, the distance between the stranding sleeve and the rotating disk can be controlled by the set moving mechanism, thereby adjusting the precision of stranding. However, while the stranding sleeve moves, the angle at which the cable wire enters the stranding sleeve and the angle between the cable wire and the rotating disk will change, causing the cable wire to tilt to a certain extent. When the tilted cable wire moves during stranding, it will contact the inner wall of the stranding sleeve and the rotating disk and generate friction, resulting in wire wear and increasing the risk of wire breakage. Utility Model Content

[0005] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a power cable stranding machine that solves the problems mentioned in the background art, such as the change in the angle of the cable wire when adjusting the position of the stranding sleeve, and the contact and friction between the inclined cable wire and the inner wall of the stranding sleeve and the rotating disc during stranding movement, leading to wire wear and increased risk of wire breakage.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A power cable stranding machine, comprising:

[0008] A base, on which a stranding machine is mounted, a stranding mold is slidably mounted, a stranding reel is mounted on the stranding machine, the reel has wire holes, and the stranding mold has stranding holes; characterized in that it further includes:

[0009] An adjustment structure, located on the base, is used to adjust the position of the twisting die;

[0010] A support structure, arranged on the base, is used to support the cable wires;

[0011] An extrusion structure, placed on a support structure, is used to change the angle of the cable wires.

[0012] Preferably, the adjustment structure includes a multi-stage hydraulic cylinder, which is arranged on the base, and the telescopic end of the multi-stage hydraulic cylinder is arranged on one side of the twisting mold.

[0016] Several threading holes are evenly spaced inside the guide turntable;

[0017] Several guide wheels are rotatably installed in corresponding wire holes, with the guide wheels corresponding to the wire holes.

[0018] Preferably, the support structure further includes several connecting rods, which are installed inside the guide turntable. One end of the connecting rod is installed on one side of the stranded wire reel, and is used to drive the guide turntable to rotate with the stranded wire reel.

[0019] Preferably, the extrusion structure includes:

[0020] The linkage turntable is rotatably mounted inside the support frame;

[0021] Several U-shaped sliding rods are evenly and slidably installed inside the linkage turntable;

[0022] The connecting frame is arranged on the corresponding U-shaped slide bar;

[0023] The U-shaped frame is slidably installed inside the connecting frame;

[0024] Pressure roller one and pressure roller two are rotatably installed inside the U-shaped frame and the connecting frame, respectively;

[0025] An adjustment component, arranged on a U-shaped slide bar, is used to adjust the squeezing force on the cable wire;

[0026] The limiting component, arranged on the U-shaped frame, is used to adjust the distance between pressure roller one and pressure roller two.

[0027] Preferably, the adjustment component includes:

[0028] The linkage ring is rotatably mounted on the linkage turntable and movably installed inside the U-shaped slide rod;

[0029] Several connecting rods are evenly rotated and mounted on the linkage ring, with one end of each connecting rod rotated and mounted inside the corresponding U-shaped slide rod;

[0036] The beneficial effects of this utility model are as follows:

[0037] In this invention, the cable wire can be passed between pressure roller one and pressure roller two. Under the pressure of pressure roller one and pressure roller two, the angle at which the cable wire enters the stranding hole can be changed, ensuring that the cable wire can enter the stranding hole at a suitable angle, thereby reducing the friction between the cable wire and the inner wall of the stranding hole. Furthermore, the guide roller can prevent the cable wire from rubbing against the inner wall of the wire hole or the through hole, thereby preventing the cable wire from twisting or breaking due to friction and improving the overall strength of the stranded wire.

It can also be used in conjunction with tightening a limit screw and rotating a linkage ring to simultaneously adjust the positions of multiple pressure rollers, thereby adjusting the angle at which the cable wire enters the stranding hole. This allows for adjustment of the cable wire angle based on the movement distance of the stranding die. Attached Figure Description

Detailed Implementation

[0048] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Example 1:

[0050] like Figures 1 to 6 As shown, this utility model provides a power cable stranding machine, including: a base 1, a stranding machine 101 disposed on the base 1, a stranding mold 102 slidably mounted on the base 1, a stranding reel 103 disposed on the stranding machine 101, a wire hole 104 opened on the stranding reel 103, and a stranding hole 105 opened on the stranding mold 102; it also includes an adjustment structure arranged on the base 1 for adjusting the position of the stranding mold 102.

[0051] The adjustment structure includes a multi-stage hydraulic cylinder 2 arranged on the base 1. The telescopic end of the multi-stage hydraulic cylinder 2 is arranged on one side of the stranding mold 102. Activating the multi-stage hydraulic cylinder 2 can cause its telescopic end to drive the stranding mold 102 to slide on the base 1. Adjusting the distance between the stranding hole 105 and the linkage turntable 4 can change the strand density.

[0052] Example 2:

[0053] Based on Example 1, in order to reduce the friction between the cable wire and the wire hole 104 when the cable wire moves, a support structure for supporting the cable wire is arranged on the base 1.

[0054] The support structure includes a support frame 3 arranged above the base 1, a guide turntable 301 rotatably installed inside the support frame 3, a plurality of wire holes 302 evenly opened inside the guide turntable 301, and a plurality of guide wheels 303 rotatably installed in the corresponding wire holes 302. The guide wheels 303 correspond to the wire holes 104, and the outer surface of the guide wheels 303 is flush with the wire holes 104, so that when the cable wire is tilted, it will contact the surface of the guide wheel 303 near the outer ring. When the cable wire moves, it can drive the corresponding guide wheel 303 to rotate. Thus, the guide wheels 303 can prevent the cable wire from rubbing against the inner wall of the wire hole 104 or the wire hole 302 when it is tilted.

[0055] The support structure also includes several connecting rods 304 installed inside the guide turntable 301 to drive the guide turntable 301 to rotate with the stranding disc 103. One end of the connecting rod 304 is installed on one side of the stranding disc 103. When the stranding machine 101 is running and stranding wire, it will drive the stranding disc 103 to rotate, so that the stranding disc 103 can drive the guide turntable 301 to rotate through the connecting rods 304.

[0056] Example 3:

[0057] Based on Example 1, in order to reduce the friction between the cable wire and its inner wall when the cable wire enters the stranding hole 105, a compression structure for changing the angle of the cable wire is arranged on the support structure.

[0058] The extrusion structure includes a rotating turntable 4 rotatably installed inside the support frame 3, several U-shaped slide rods 401 slidably installed inside the rotating turntable 4, a connecting frame 402 arranged on the corresponding U-shaped slide rods 401, a U-shaped frame 403 slidably installed inside the connecting frame 402, pressure roller 404 and pressure roller 405 rotatably installed inside the U-shaped frame 403 and the connecting frame 402 respectively, an adjustment component arranged on the U-shaped slide rod 401 for adjusting the extrusion force on the cable wire, and a limiting component arranged on the U-shaped frame 403 for adjusting the distance between pressure roller 404 and pressure roller 405. In use, the cable wire to be twisted can be passed between the corresponding pressure roller 404 and pressure roller 405. When the twisting disc 103 rotates, it can drive the rotating turntable 4 to rotate through the connecting rod 304, so that the cable wire can rotate with it. The pressure roller 404 and pressure roller 405 can prevent the position of the cable wire from shifting during the twisting process.

[0059] Specifically, the adjustment assembly includes a linkage ring 406 rotatably mounted on the linkage turntable 4 and movably installed inside the U-shaped slide rod 401; several connecting rods 407 rotatably mounted on the linkage ring 406; one end of each connecting rod 407 rotatably mounted inside the corresponding U-shaped slide rod 401; several limiting holes 408 evenly opened inside the linkage ring 406; and a limiting screw 409 threaded inside the linkage turntable 4, passing through the corresponding limiting holes 408. Rotating and unscrewing the limiting screw 409 releases the restriction on the linkage ring 406. Subsequently, rotating the linkage ring 406 causes several connecting frames 402 to move simultaneously via the connecting rods 407. When the connecting frames 402 move, they cause pressure roller 1 404 or pressure roller 2 405 to squeeze the cable wire and change the angle at which the cable wire enters the twisting hole 105.

[0060] Specifically, the limiting component includes an adjusting screw 410 rotatably mounted on one side of the U-shaped frame 403. The adjusting screw 410 is threaded inside the connecting frame 402. Rotating the adjusting screw 410 can cause the U-shaped frame 403 to slide. The U-shaped frame 403 will drive the pressure roller 1 404 to squeeze the cable wire and make it fit against the pressure roller 2 405.

[0061] Specifically, the limiting component also includes a pressing screw 411 threaded inside the connecting frame 402 and an inclined block 412 arranged on one side of the U-shaped frame 403. One end of the pressing screw 411 contacts the inclined surface of the inclined block 412. When the U-shaped frame 403 moves, it can drive the corresponding inclined block 412 to move. By rotating the corresponding pressing screw 411, one end of it can be pressed against the inclined surface of the inclined block 412, thereby preventing the U-shaped frame 403 from loosening and improving its stability.

[0062] Working principle: During use, the cable wires to be twisted are passed through the corresponding threading hole 302 and contact the guide wheel 303. Then, they are passed between pressure roller 1 404 and pressure roller 2 405. Rotating the adjusting screw 410 allows it to engage with the connecting frame 402, causing the U-shaped frame 403 to slide within the connecting frame 402. The U-shaped frame 403 moves pressure roller 1 404 closer to pressure roller 2 405, causing pressure roller 1 404 to squeeze the cable wire and make it adhere to pressure roller 2 405. The movement of the U-shaped frame 403 also moves the corresponding inclined block 412. After adjustment, the corresponding pressing screw 411 can be rotated. The rotating pressing screw 411... The U-shaped frame 403 moves by engaging with the connecting frame 402 through a threaded connection, allowing the pressing screw 411 to press against the inclined surface of the inclined block 412, thus preventing the U-shaped frame 403 from loosening. The cooperation of pressure roller 1 404 and pressure roller 2 405 prevents the cable wires from shifting during the twisting process. Before twisting, the limiting screw 409 can be rotated to release the restriction on the linkage ring 406. Rotating the linkage ring 406 then moves one end of several connecting rods 407, causing the other ends of these connecting rods 407 to simultaneously drive the U-shaped slide rod 401 to slide within the linkage turntable 4, thereby causing several connecting frames 402 to move simultaneously in directions closer to or further apart from each other. When the connecting bracket 402 moves, it drives pressure roller 1 404 or pressure roller 2 405 to squeeze the cable wire and change the angle at which the cable wire enters the stranding hole 105, reducing the friction between the cable wire and the inner wall of the stranding hole 105. Simultaneously, it causes the cable wire to tilt to a certain degree, making a portion of the cable wire contact the surface of the guide wheel 303 near the outer ring. The outer ring surface of the guide wheel 303 is flush with the wire hole 104. When the cable wire moves, it drives the corresponding guide wheel 303 to rotate. Thus, the guide wheel 303 prevents the cable wire from rubbing against the inner wall of the wire hole 104 or the through hole 302 when tilted. After adjustment, the limiting screw 409 can be re-inserted into the corresponding limiting insertion hole 408. The position is fixed by screwing it into the linkage turntable 4. By opening the multi-stage hydraulic cylinder 2, its telescopic end can drive the stranding mold 102 to slide on the base 1. The spacing between the stranding hole 105 and the linkage turntable 4 can be adjusted to change the stranding density. By setting multiple limit holes 408, the squeezing force of the pressure roller 1 404 and the pressure roller 2 405 can be adjusted according to the usage requirements. According to the prior art, when the stranding machine 101 is running and stranding, it will drive the stranding disc 103 to rotate, so that the stranding disc 103 can drive the guide turntable 301 and the linkage turntable 4 to rotate through the connecting rod 304, so that the cable wire can follow its rotation, pass through the stranding hole 105 and be stranded with the cable core.

[0063] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
