Description

Technical Field

[0001] The present invention relates to the technical field of cable production, and in particular to a supporting frame for cable production. Background Art

[0002] Cable production is a complex process involving multiple links, such as wire drawing, stranding, insulation extrusion, sheath extrusion, etc. During this process, the cable needs to be stably supported and guided to ensure the accuracy of its shape and size as well as the integrity of its internal structure;

[0003] In cable production, unstable support can cause bending, deformation, scratching and other problems in the cable during the production process, affecting product quality and production efficiency. With the advancement of technology and the improvement of cable quality requirements, specially designed support frames for cable production have emerged;

[0004] During the cable production process, various reasons such as the start and stop and acceleration of the traction machine and the poor operation of the winding equipment will suddenly cause great pulling force and impact force on the cable. The sudden impact force will cause the conductor inside the cable to displace or deform, affecting the performance of the cable. For some cables with multi-layer structures, such as cables containing shielding layers or sheaths, the impact force may make the structure between the layers loose and destroy the synergy between them, thereby reducing the overall mechanical and electrical properties of the cable, and causing limitations.

[0005] To this end, we propose a support frame for cable production. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention provides a support frame for cable production, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0007] To achieve the above object, the present invention provides the following technical solution: a support frame for cable production, comprising: a base, a mounting block and a support block; the mounting block is slidably connected to the base up and down and fixed by bolts; the support block is mounted on the mounting block;

[0008] The base is provided with a buffer mechanism; the buffer mechanism stretches a section of the cable and releases the stretched cable when the cable is subjected to impact force, thereby buffering the impact.

[0009] Preferably, the buffer mechanism includes a buffer block, a buffer spring and a stretching block; the buffer block is fixedly connected to the mounting block, and a buffer groove is provided on the buffer block; the stretching block is slidably connected in the buffer groove; the two ends of the buffer spring are respectively fixedly connected to the buffer block and the stretching block; and a No. 1 stretching rod and a No. 2 stretching rod are installed on the stretching block.

[0010] Preferably, the No. 1 stretching rod is in an inverted S shape, and is fixedly connected to the stretching block; the No. 2 stretching rod is cylindrical, and is rotatably connected to the stretching block.

[0011] By arranging a buffer block, a buffer spring and a stretching block, the cable passes through the No. 1 stretching rod and the No. 2 stretching rod on the stretching block. When the cable is suddenly subjected to a large tensile force, the buffer spring can buffer the impact on the cable, thereby protecting the cable.

[0012] Preferably, a release rod is fixedly connected to the stretching block; a release groove is provided on the buffer block; a release shaft is rotatably connected in the release groove; a No. 1 magnet block is evenly fixedly connected in the release groove; a No. 2 magnet block opposite to the No. 1 magnet block is evenly fixedly connected to the release shaft; a ratchet is fixedly connected to the release shaft; a pawl is evenly fixedly connected to the release rod; when the buffer spring is extended in length, the ratchet and the release shaft are driven to rotate by the pawl on the release rod.

[0013] By setting the ratchet and pawl, when the stretching block moves back, the release shaft is driven to rotate, so that the magnetic force of the No. 1 magnet block causes the release shaft to rotate slowly, slowing down the rebound speed of the buffer spring. On the one hand, the rapid rebound of the buffer spring can avoid damage to the cable and ensure that the force applied to the cable is more stable during the whole process. On the other hand, slowly releasing the elastic force of the buffer spring can reduce the violent movement of the stretching block and the cable caused by the sudden release of the elastic force, thereby making the whole buffering process more controllable and reducing the impact and wear on related components.

[0014] Preferably, a No. 1 mounting ring is fixedly connected to the mounting block; a movable rack is fixedly connected to the No. 1 mounting ring; a No. 2 mounting ring is slidably connected to the movable rack; a No. 2 mounting ring is also fixedly connected to the movable rack; a No. 3 mounting ring is slidably connected to the movable rack on the No. 2 mounting ring.

[0015] Preferably, the No. 1 mounting ring, the No. 2 mounting ring and the No. 3 mounting ring are all provided with open grooves; a closing block is slidably connected in the open groove; and the closing block is fixed in the open groove by bolts.

[0016] Preferably, movable grooves are provided in the second mounting ring and the third mounting ring; a movable motor is fixedly connected in the movable groove; and a gear meshing with the movable rack is fixedly connected to the output end of the movable motor.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention provides a buffer block, a buffer spring and a stretching block, so that the cable passes through the No. 1 stretching rod and the No. 2 stretching rod on the stretching block. When the cable is suddenly subjected to a large tensile force, the buffer spring can buffer the impact on the cable, thereby protecting the cable.

[0019] 2. The present invention arranges a ratchet and a pawl, and when the stretching block moves back, the release shaft is driven to rotate, so that the magnetic force of the No. 1 magnet block causes the release shaft to rotate slowly, slowing down the rebound speed of the buffer spring. On the one hand, the rapid rebound of the buffer spring can avoid damage to the cable, ensuring that the force applied to the cable is more stable during the whole process. On the other hand, the slowly releasing elastic force of the buffer spring can reduce the violent movement of the stretching block and the cable caused by the sudden release of the elastic force, thereby making the whole buffering process more controllable and reducing the impact and wear on related components.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: Refer to the attached specification Figure 1 , 2 , 3, 4, 5, and 6, a support frame for cable production, comprising: a base 1, a mounting block 11 and a support block 12; the mounting block 11 is slidably connected to the base 1 up and down and fixed by bolts; the support block 12 is mounted on the mounting block 11;

[0030] A buffer mechanism is provided on the base 1; the buffer mechanism stretches a section of the cable and releases the stretched cable when the cable is subjected to impact force, thereby buffering the impact.

[0031] In the present invention, the buffer mechanism includes a buffer block 21, a buffer spring 22 and a stretching block 23; the buffer block 21 is fixedly connected to the mounting block 11, and a buffer groove 24 is provided on the buffer block 21; the stretching block 23 is slidably connected in the buffer groove 24; the two ends of the buffer spring 22 are respectively fixedly connected to the buffer block 21 and the stretching block 23; and a No. 1 stretching rod 25 and a No. 2 stretching rod 26 are installed on the stretching block 23.

[0032] In the present invention, the first stretching rod 25 is in an inverted S shape and is fixedly connected to the stretching block 23 ; the second stretching rod 26 is cylindrical and is rotatably connected to the stretching block 23 .

[0033] In the present invention, the two vertical rods on the support block 12 are located on both sides of the cable, the support block 12 supports the cable, and the cable passes between the No. 1 stretching rod 25 and the No. 2 stretching rod 26 on the stretching block 23, and the No. 1 stretching rod 25 is arranged in an inverted S shape, which can facilitate the cable to be inserted between the No. 1 stretching rod 25 and the No. 2 stretching rod 26, and makes it difficult for the cable to slip off the No. 1 stretching rod 25 and the No. 2 stretching rod 26;

[0034] When the cable is suddenly subjected to a large tension or impact, the cable will pull the second stretching rod 26, so that the stretching block 23 squeezes the buffer spring 22, so that the buffer spring 22 absorbs the tension on the cable, relieves the sudden tension on the cable, and buffers the impact;

[0035] The present invention provides a buffer block 21, a buffer spring 22 and a stretching block 23, so that the cable passes through a first stretching rod 25 and a second stretching rod 26 on the stretching block 23. When the cable is suddenly subjected to a large tensile force, the buffer spring 22 can buffer the impact on the cable, thereby protecting the cable.

[0036] In the present invention, a release rod 3 is fixedly connected to the stretching block 23; a release groove 31 is provided on the buffer block 21; a release shaft 32 is rotatably connected in the release groove 31; a No. 1 magnet block 33 is evenly fixedly connected in the release groove 31; a No. 2 magnet block 34 opposite to the No. 1 magnet block 33 is evenly fixedly connected to the release shaft 32; a ratchet 35 is fixedly connected to the release shaft 32; a pawl 36 is evenly fixedly connected to the release rod 3; when the buffer spring 22 is extended in length, the ratchet 35 and the release shaft 32 are driven to rotate by the pawl 36 on the release rod 3.

[0037] In the present invention, the buffer spring 22 is squeezed and compressed during the process of buffering the impact on the cable. During this process, the release rod 3 moves forward with the pawl 36; after the impact on the cable disappears, the buffer spring 22 rebounds, driving the release rod 3 and the pawl 36 to move back, so that the pawl 36 is stuck by the ratchet 35, thereby driving the release shaft 32 and the second magnet block 34 to rotate through the ratchet 35, and the first magnet block 33 in the release groove 31 generates a magnetic force on the second magnet block 34, so that the rotation of the release shaft 32 is slowed down, so that the release rod 3 pulls the stretching block 23, the buffer spring 22 slowly rebounds, and the stretching block 23 slowly returns to its original position;

[0038] The present invention arranges a ratchet 35 and a pawl 36, and when the stretching block 23 moves back, the release shaft 32 is driven to rotate, so that the magnetic force of the No. 1 magnet block 33 causes the release shaft 32 to rotate slowly, slowing down the rebound speed of the buffer spring 22. On the one hand, it avoids the damage to the cable caused by the rapid rebound of the buffer spring 22, ensuring that the force applied to the cable is more stable during the whole process. On the other hand, the slowly releasing elastic force of the buffer spring 22 can reduce the violent movement of the stretching block 23 and the cable caused by the sudden release of the elastic force, thereby making the whole buffering process more controllable and reducing the impact and wear on related components.

[0039] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 1 , 2 , 3, 4 and 6, in the present invention, a No. 1 mounting ring 4 is fixedly connected to the mounting block 11; a movable rack 41 is fixedly connected to the No. 1 mounting ring 4; a No. 2 mounting ring 42 is slidably connected to the movable rack 41; the No. 2 mounting ring 42 is also fixedly connected to the movable rack 41; a No. 3 mounting ring 43 is slidably connected to the movable rack 41 on the No. 2 mounting ring 42.

[0040] In the present invention, the first mounting ring 4, the second mounting ring 42 and the third mounting ring 43 are all provided with an opening groove 44; a closing block 45 is slidably connected in the opening groove 44; and the closing block 45 is fixed in the opening groove 44 by bolts.

[0041] In the present invention, a moving groove 46 is formed in the second mounting ring 42 and the third mounting ring 43 ; a moving motor 47 is fixedly connected in the moving groove 46 ; and a gear meshing with the moving rack 41 is fixedly connected to the output end of the moving motor 47 .

[0042] In the present invention, when placing the cable on the support block 12, unscrew the bolts on the closing block 45, then remove the closing block 45, put the cable into the No. 1 mounting ring 4, the No. 2 mounting ring 42 and the No. 3 mounting ring 43, and then install the closing ring, so that the moving motor 47 in the No. 2 mounting ring 42 and the No. 3 mounting ring 43 drives the corresponding gears to rotate, so that the No. 2 mounting ring 42 and the No. 3 mounting ring 43 move back and forth on the outside of the cable, thereby preventing the cable from shaking and resonating during the movement, and the resonance causing damage to the cable.
