Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of cable forming apparatus technology, and more specifically, to a cable forming machine for wires and cables. Background Technology

[0002] In the manufacturing process of wires and cables, cabling is one of the core processes. Its function is to twist multiple insulated cores into a cable core according to design requirements, while ensuring the stability of the cable core structure and the compliance of electrical performance standards, laying the foundation for subsequent sheath processing and other stages. The pre-tightening force required for stranding wires and cables of different specifications and materials varies significantly. The pre-tightening structure of existing cabling machines is mostly a fixed design, and the pre-tightening force cannot be precisely adjusted according to the characteristics of the cable. If the pre-tightening force is too small, it cannot effectively eliminate the slack during cable stranding, resulting in an unstable cable core structure; if the pre-tightening force is too large, it is easy to cause the cable to stretch and deform, damage the insulation layer, and affect the electrical insulation performance of the cable. Therefore, a cabling machine for wires and cables has been designed. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a cable-making machine for wires and cables, which solves the technical problem that swaying and rotation easily occur when prefabricated components are hoisted by hoisting devices in the prior art, resulting in poor hoisting effect.

[0004] According to one aspect, at least one embodiment of this disclosure provides a cable-forming machine for wires and cables, including a main shaft. One end of the main shaft is fixedly connected to a main rotating disk, and the end of the main shaft away from the main rotating disk is fixedly connected to a secondary rotating disk. A plurality of cradle frames are rotatably connected between the main rotating disk and the secondary rotating disk. A plurality of pre-tensioning frames are fixedly connected to the outer wall of the secondary rotating disk and to the front end of the secondary rotating disk. A toothed plate is slidably connected to the inner wall of the pre-tensioning frame. A rotating shaft is rotatably connected to the top of the pre-tensioning frame. A gear is fixedly connected to the outer wall of the rotating shaft, and the gear meshes with the toothed plate. One end of the rotating shaft extends out of the outer wall of the pre-tensioning frame. A worm gear is fixedly connected to the extended end of the rotating shaft. A worm is rotatably connected to the end of the pre-tensioning frame near the worm gear, and the worm meshes with the worm gear. A pre-tensioning frame is fixedly connected to the bottom end of the toothed plate.

[0005] For example, at least one embodiment of this disclosure provides a cable-making machine for wires and cables, wherein a transmission box is driven to the back of the main rotating disk, and a motor is fixedly connected to the back of the transmission box.

[0006] For example, at least one embodiment of this disclosure provides a cable forming machine for wires and cables, wherein a winding wheel is symmetrically rotatably connected to the inner wall of the cradle frame, and a threading shaft is rotatably connected at the connection between the cradle frame and the auxiliary rotating disk.

[0007] For example, at least one embodiment of this disclosure provides a cable-forming machine for wires and cables, wherein a support frame is provided at the bottom end of the auxiliary rotating disk, and two auxiliary wheels are symmetrically rotatably connected to the inner wall of the support frame.

[0008] For example, at least one embodiment of this disclosure provides a cable-making machine for wires and cables, wherein the top end of the worm extends out of the top of the pre-tensioning frame, and a handwheel is fixedly connected to the extended end of the worm.

[0009] For example, at least one embodiment of this disclosure provides a cable-forming machine for wires and cables, wherein the outer wall of the pre-tightening frame is slidably connected to the inner wall of the pre-tightening bracket, and two auxiliary rollers are symmetrically fixedly connected to the inner wall of the pre-tightening frame.

[0010] For example, at least one embodiment of this disclosure provides a cable-forming machine for wires and cables, wherein a plurality of sliding frames are arranged around one end of the auxiliary rotating disk near the pre-tightening frame, and two guide rods are symmetrically fixedly connected to the inner wall of the sliding frames.

[0011] For example, at least one embodiment of this disclosure provides a cable-forming machine for wires and cables, wherein an adjusting frame is slidably connected to the outer wall of the guide rod, and a winding wheel is rotatably connected to the inner wall of the adjusting frame.

[0012] For example, at least one embodiment of this disclosure provides a cable forming machine for wires and cables, wherein a lead screw is threadedly connected to the inner wall of the sliding frame, and the outer wall of the lead screw is threadedly connected to the inner wall of the adjusting frame.

[0013] For example, at least one embodiment of this disclosure provides a cable forming machine for wires and cables, wherein a stranding disc is fixedly connected to the front end of the main shaft, and a plurality of wire-passing holes are arranged around the inner wall of the stranding disc.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: 1. Compared with traditional devices, this utility model has a pre-tightening frame at the front end of the auxiliary rotating disk. The pre-tightening frame guides and pre-tightens the twisting direction of the cable, thereby improving the quality of the cable. The operator can adjust the height of the pre-tightening frame by rotating the worm gear, thereby adjusting the direction of guidance and the pre-tightening force. The rotation of the worm gear drives the worm wheel and the rotating shaft to rotate through meshing. The rotating shaft then drives the pre-tightening frame to rise and fall through the meshing of gears and toothed plates, thereby achieving the effect of adjusting the pre-tightening.

[0015] 2. Compared with traditional devices, this utility model has an adjustment frame and a sliding frame at the front end of the auxiliary rotating plate. By sliding the adjustment frame and the sliding frame, the height of the winding wheel can be adjusted, thereby cooperating with the pre-tightening frame to orderly and stably twist the filler wire with the core wire, improving the twisting stability. The operator can adjust the sliding of the adjustment frame by rotating the screw. The rotation of the screw, through the threaded connection, pushes the adjustment frame to slide on the inner wall of the sliding frame. The sliding frame drives the winding wheel to slide towards the axis of the main shaft, thereby adjusting the position of the twisting height of the filler rope, and cooperating with the pre-tightening frame to achieve tight twisting.

[0024] like Figures 1-5The diagram illustrates a cable-forming machine for wires and cables according to an embodiment of this disclosure. It includes a main shaft 1, one end of which is fixedly connected to a main rotating disk 2. An auxiliary rotating disk 201 is fixedly connected to the end of the main shaft 1 away from the main rotating disk 2. Multiple cradle frames 3 are rotatably connected between the main rotating disk 2 and the auxiliary rotating disk 201. Multiple pre-tensioning frames 4 are fixedly connected to the outer wall of the auxiliary rotating disk 201 and to its front end. The inner wall of each pre-tensioning frame 4 is slidably connected to... A rotating shaft 402 is rotatably connected to the top of the toothed plate 401 and the pretensioning frame 4. A gear 403 is fixedly connected to the outer wall of the rotating shaft 402. The gear 403 meshes with the toothed plate 401. One end of the rotating shaft 402 extends out of the outer wall of the pretensioning frame 4. A worm gear 404 is fixedly connected to the extended end of the rotating shaft 402. A worm 405 is rotatably connected to the end of the pretensioning frame 4 near the worm gear 404. The worm 405 meshes with the worm gear 404. A pretensioning frame 407 is fixedly connected to the bottom end of the toothed plate 401.

[0025] It should be noted that...

[0026] In some examples, such as Figures 1 to 5 As shown, a transmission box 202 is connected to the back of the main rotating disk 2, and a motor 203 is fixedly connected to the back of the transmission box 202.

[0027] It should be noted that the inner wall of the transmission box 202 is provided with multiple gears that mesh with each other. At the same time, the input end of the transmission box 202 is connected to the output end of the motor 203. After the motor 203 is started, it will drive the main rotating disk 2 and the cradle frame 3 to rotate synchronously through the transmission box 202.

[0028] In some examples, such as Figures 1 to 5 As shown, a winding wheel 301 is symmetrically and rotatably connected to the inner wall of the cradle frame 3. A threading shaft 302 is rotatably connected to the connection between the cradle frame 3 and the auxiliary rotating disk 201. A support frame 204 is provided at the bottom of the auxiliary rotating disk 201. Two auxiliary wheels 205 are symmetrically and rotatably connected to the inner wall of the support frame 204.

[0029] It should be noted that the winding wheel 301 is a winding wheel for the wire core. The winding wheel 301, which is fully wound with the wire core, is set on the inner wall of the cradle frame 3 by a hoist. Then, the operator needs to manually install the winding wheel 301 on the inner wall of the cradle frame 3 through the connected shaft. The support frame 204 and the auxiliary wheel 205 are used to support the rotation of the auxiliary rotating disk 201.

[0030] In some examples, such as Figures 1 to 5 As shown, the top of the worm gear 405 extends out of the top of the pretensioning frame 4. A handwheel 406 is fixedly connected to the extended end of the worm gear 405. The outer wall of the pretensioning frame 407 is slidably connected to the inner wall of the pretensioning frame 4. Two auxiliary rods 408 are symmetrically fixedly connected to the inner wall of the pretensioning frame 407.

[0031] It should be noted that the pre-tightening frame 4 has a bearing seat on one side of the outer wall. The bearing seat is used to support the rotation of the worm gear 405. The worm gear 405 is rotated by the handwheel 406. The wire core is clamped by the two auxiliary rollers 408 to stably push the wire core for pre-tightening.

[0032] In some examples, such as Figures 1 to 5 As shown, multiple sliding frames 5 are arranged around one end of the auxiliary rotating disk 201 near the pre-tightening frame 4. Two guide rods 503 are symmetrically fixedly connected to the inner wall of the sliding frame 5. An adjusting frame 504 is slidably connected to the outer wall of the guide rods 503. A winding wheel 501 is rotatably connected to the inner wall of the adjusting frame 504. A lead screw 502 is threadedly connected to the inner wall of the sliding frame 5. The outer wall of the lead screw 502 is threadedly connected to the inner wall of the adjusting frame 504.

[0033] It should be noted that the second winding wheel 501 is used to wind the filler rope. When the operator rotates the lead screw 502, the lead screw 502 pushes the adjusting frame 504 to slide on the inner wall of the sliding frame 5 through the threaded connection. Under the guidance of the guide rod 503, the adjusting frame 504 slides towards the axis of the main shaft 1. The adjusting frame 504 drives the second winding wheel 501 to slide synchronously, thereby realizing the adjustment of the twisting direction of the filler rope.

[0034] The specific operation is as follows: The operator needs to pre-wrap the core wire around the outer wall of the first winding wheel 301 and pre-wrap the filler rope around the outer wall of the second winding wheel 501. Then, the end of the wire from the first winding wheel 301 is pulled out and passed through the inner wall of the threading shaft 302. Next, the wire is passed through the two auxiliary rollers 408 on the inner wall of the pre-tensioning frame 407. Then, the passed-through end of the wire is passed through the inner wall of the threading hole 304. After the core wire is passed through, the filler rope is interlaced and passed through the inner walls of the remaining threading holes 304. The operation is then carried out by subsequent traction. The inserted filler rope and core wire are twisted together. The operator needs to start motor 203. Motor 203 drives transmission box 202 via its output end. Transmission box 202 then drives the main shaft 1 and main rotating disk 2 to rotate. The main rotating disk 2, while rotating, drives multiple cradle frames 3 to rotate synchronously. The cradle frames 3 drive the winding wheel 301 to rotate. At this time, the traction and twisting of the core wire will rotate and twist. The operator can adjust the twisting direction of the core wire by rotating handwheel 406. Handwheel 406 drives worm gear 405 to rotate. Worm gear 405 rotates through meshing, which in turn drives rotating shaft 402 and gear 403 to rotate. Gear 403, through meshing, drives gear plate 401 to rise and fall on the inner wall of pre-tightening frame 4. Gear 403 pushes pre-tightening frame 407 to rise and fall. Pre-tightening frame 407 moves up and down by pushing the outer wall of wire core through auxiliary roller 408, thereby adjusting the twisting direction of wire core. At the same time, the twisting direction of filling rope can also be adjusted by rotating lead screw 502. When lead screw 502 rotates, it pushes adjusting frame 504 to slide on the inner wall of sliding frame 5 through threaded connection. Adjusting frame 504 drives winding wheel 501 to slide, thereby adjusting the twisting direction of filling rope. Finally, main shaft 1 drives auxiliary rotating disk 201 and twisting disk 303 to rotate, rotating the adjusted filling rope and wire core, and twisting them into cable.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
