Description

Technical Field

[0001] This utility model relates to the field of manufacturing and processing technology, specifically to a cable core forming device. Background Technology

[0002] In cable production, the forming of the cable core is a crucial step. During core forming, a certain amount of pressure needs to be applied to ensure structural stability and reliability. However, excessive pressure during the forming process often causes the winch to rotate. This rotation not only affects the stability of the forming process but can also damage the equipment, especially after motor repair or replacement, when the winch's normal operating condition cannot be restored in a timely manner.

[0003] Furthermore, when the cable core is formed and subjected to excessive pressure, and then re-extruded after the pressure is released, the cable core will be subjected to compressive forces from both sides. This may lead to unstable quality of the cable core, thereby affecting its service life, especially under high-strength forming conditions, where the long-term stability and service life of the cable core are easily affected. Therefore, we propose a cable core forming device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a cable core forming device to solve the problem mentioned in the background art of how to effectively control the pressure applied during the forming process while ensuring the forming accuracy of the cable core, avoiding winch rotation, and improving the stability of the formed cable core.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable core forming device, comprising a bracket, a forming structure fixedly installed at the top of the bracket, the forming structure comprising a shell, the shell being fixedly installed at the top of the bracket, a rotating shaft I inserted inside the shell, and a circular gear I fixedly installed on the outer side of the rotating shaft I, a winch inserted inside the shell, the winch having a winch hole inside, a connecting structure fixedly installed on the outer side of the bracket, the connecting structure comprising a fixing block, the fixing block being fixedly installed on the outer side of the bracket, a rotating shaft II inserted inside the fixing block, and a circular gear III fixedly installed on the outer side of the rotating shaft II, the circular gear III meshing with the circular gear I through teeth, a limiting component fixedly installed on the side of the fixing block near the circular gear III, the limiting component being used to limit the rotation direction of the rotating shaft II, and a driving structure fixedly installed on the outer side of the bracket.

[0006] Preferably, the limiting component includes a disc, and a fixing block is fixedly mounted on the side of the disc near the circular gear three. A ratchet is fixedly mounted on the outer side of the rotating shaft two, and the ratchet is located between the disc and the circular gear three. A hinge rod is fixedly mounted on the side of the disc near the ratchet, and ratchet teeth are hinged on the outer side of the hinge rod. A spring is fixedly mounted on the outer side of the ratchet teeth. A fixing plate is fixedly mounted on the side of the disc near the ratchet.

[0007] Preferably, the fixing plate is fixedly mounted on the other end of the spring on the side near the disc, and the teeth of the ratchet mesh with the teeth of the ratchet wheel.

[0008] Preferably, the hinge rod, ratchet, spring and fixing plate are arranged in four groups at equal intervals, and the four groups of hinge rod, ratchet, spring and fixing plate are arranged in an array around the central axis of the second pivot.

[0009] Preferably, a guide structure is fixedly installed on one side of the winch, and the guide structure includes a guide block. The guide block is fixedly installed on one side of the winch, and a guide groove is formed inside the guide block.

[0010] Preferably, the guide groove is positioned to correspond to the winch hole, and the other end of the guide groove is located on the side of the guide groove away from the winch and is distributed in a clustered manner. The cross-section of the guide groove is inclined.

[0011] Preferably, the drive structure includes a motor, which is fixedly mounted on the outside of the bracket. A second circular gear is fixedly mounted on the rotation output shaft of the motor, and the second circular gear is located directly below the fixed block. The second circular gear and the third circular gear mesh with each other through their teeth.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) This structure, through the cooperation of four sets of springs and four sets of ratchet teeth with the ratchet wheel, ensures that the ratchet wheel can only rotate in one direction, and will be stopped by the ratchet teeth when rotating in the opposite direction. In this way, when the drive structure meshes with the third circular gear, the third circular gear can only move in one direction; at the same time, when the third circular gear meshes with the first circular gear, the rotation direction of the winch driven by the first circular gear is restricted, avoiding the impact of damage to the drive structure. This design ensures that the winch stably forms and extrudes the cable core, avoids the cable core from rotating, and thus improves the stability and service life of the cable core forming; (2) A guide structure is fixedly installed on one side of the winch. The structure includes a guide block, which is fixed on one side of the winch and has a guide groove inside. The position of the guide groove corresponds to the winch hole. The end away from the winch is distributed in a clustered manner and the cross-section is inclined. This design can slowly apply force to the cable core during the forming process through the inclined surface of the guide groove, thereby improving the stability of the forming process, reducing the risk of cable core breakage, and increasing the distance between the intersection point and one side of the winch during the forming process.

[0016] 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.

[0017] Please see Figure 1-6 One embodiment of this utility model is a cable core forming device, which includes a bracket 1 and a forming structure 2 fixedly installed on the top of the bracket 1. The molding structure 2 includes a housing 210, and the housing 210 is fixedly installed on the top of the bracket 1. A rotating shaft 220 is inserted inside the housing 210, and a circular gear 230 is fixedly installed on the outside of the rotating shaft 220. The circular gear 230 is located inside the housing 210. A winch 240 is inserted inside the outer casing 210, and the outer side of the winch 240 is provided with teeth that are compatible with the circular gear 230. The winch 240 and the circular gear 230 mesh with each other through the teeth. The winch 240 has a winch hole 250 inside, and six sets of winch holes 250 are arranged at equal intervals. The six sets of winch holes 250 are arranged in an array around the central axis of the winch 240. Connection structure 5 is fixedly installed on the outside of bracket 1; The connecting structure 5 includes a fixing block 510, which is fixedly installed on the outside of the bracket 1. A rotating shaft 2 520 is inserted inside the fixing block 510, and a circular gear 3 530 is fixedly installed on the outside of the rotating shaft 2 520. The circular gear 3 530 meshes with the circular gear 1 230 through teeth. A limiting component 540 is fixedly installed on the side of the fixed block 510 near the circular gear 530. The limiting component 540 is used to limit the rotation direction of the rotating shaft 520. A drive structure 4 is fixedly mounted on the outer side of the bracket 1. A limiting assembly 540 includes a disc 541, with a fixing block 510 fixedly mounted on the disc 541 near the side of the circular gear 530. A ratchet 542 is fixedly mounted on the outer side of the rotating shaft 520, located between the disc 541 and the circular gear 530. A hinge rod 543 is fixedly mounted on the side of the disc 541 near the ratchet 542, and a ratchet tooth 544 is hinged to the outer side of the hinge rod 543. A [missing information - likely a device or component] is fixedly mounted on the outer side of the ratchet tooth 544. A fixing plate 546 is fixedly installed on the side of the disc 541 near the ratchet 542. The fixing plate 546 is fixedly installed on the other end of the spring 545 near the disc 541. The teeth of the ratchet 544 mesh with the teeth of the ratchet 542. The hinge rod 543, ratchet 544, spring 545 and fixing plate 546 are arranged in four sets at equal intervals. The four sets of hinge rod 543, ratchet 544, spring 545 and fixing plate 546 are arranged in an array around the central axis of the second pivot 520. This structure, through the elastic force of four sets of springs 545 and the limiting effect of four sets of ratchet teeth 544 on the teeth of ratchet 542, forms a unidirectional transmission mechanism. Specifically, the gear structure design of ratchet 542 allows it to rotate in only one direction during rotation. The four sets of ratchet teeth 544 mesh with the teeth of ratchet 542. When ratchet 542 rotates clockwise, the tooth surfaces of ratchet teeth 544 are tightly engaged with the teeth of ratchet 542, ensuring that ratchet 542 can only rotate in the set direction. This structure solves the potential risks that may arise when the drive structure 4 is damaged. Due to the limiting effect of unidirectional movement, when circular gear 1 230 meshes with circular gear 3 530, it is restricted by the engagement of ratchet 542 and ratchet teeth 544. This design ensures that the circular gear 230 can only drive the winch 240 to rotate within a limited range of directions. Therefore, when the drive structure 4 is damaged or malfunctions, the movement direction of the winch 240 will not be disturbed, preventing misoperation of the cable core. The stable rotation of the winch 240 is crucial for the forming and extrusion process of the cable core. If the winch 240 rotates unexpectedly, it can cause deviations in the shape and quality of the cable core, affecting the forming effect and even the long-term stability of the equipment. This unidirectional transmission design not only ensures the stability of the winch 240 but also effectively prevents the winch 240 from rotating the cable core at inappropriate times, thus guaranteeing the stability and accuracy of the cable core forming process.

[0018] Furthermore, a guide structure 3 is fixedly installed on one side of the winch 240, and the guide structure 3 includes a guide block 310. The guide block 310 is fixedly installed on one side of the winch 240, and a guide groove 320 is opened inside the guide block 310. The position of the guide groove 320 corresponds to the winding hole 250. The other end of the guide groove 320 is located on the side of the guide groove 320 away from the winch 240 and is distributed in a clustered manner. The cross-section of the guide groove 320 is inclined, which increases the distance between the staggered point of the winch 240 and one side of the winch 240 when the winch 240 forms the cable core through the winding hole 250. The inclined surface of the guide groove 320 allows the cable core to be formed slowly, improving the stability of the cable core forming and avoiding cable core breakage. Furthermore, the drive structure 4 includes a motor 410, which is fixedly mounted on the outside of the bracket 1. A circular gear 420 is fixedly mounted on the rotation output shaft of the motor 410, and the circular gear 420 is located directly below the fixed block 510. The circular gear 420 and the circular gear 530 mesh with each other through their teeth, so that the rotation output shaft of the motor 410 drives the circular gear 420 to rotate. The circular gear 420, the circular gear 530, the circular gear 230 and the winch 240 mesh with each other so that the winch 240 can stably shape the cable core through the winch hole 250.

[0019] The working principle and usage process of this utility model are as follows: In use, move the device to the desired location for cable core forming, install the device on the operating table, connect the external power supply, and turn on the switch. Simultaneously, pass the cable core through the winding hole 250 and install it inside the guide groove 320. Start the motor 410, and the output shaft of the motor 410 drives the second circular gear 420 to rotate. The second circular gear 420 meshes with the third circular gear 530. At this moment, the third circular gear 530 drives the second rotating shaft 520 to rotate inside the fixed block 510. Therefore, the third circular gear 530 meshes with the first circular gear 230 through tooth engagement, causing the first circular gear 230 to drive the first rotating shaft 220 to rotate inside the outer casing 210. At this moment, the first circular gear 230 meshes with the winch 240 through tooth engagement, allowing the winch 240 to stably form the cable core through the winding hole 250. Furthermore, because the cross-section of the guide groove 320 is inclined, the winch 240 forms the cable core through the winding hole 250. The increased distance between the intersection point and one side of the winch 240 allows the cable core to be slowly formed through the inclined surface of the guide groove 320, improving the stability of the cable core formation and preventing cable core breakage. Simultaneously, the circular gear 3 530 drives the ratchet 542 to rotate. The elasticity of four sets of springs 545 and the limiting effect of four sets of ratchet teeth 544 on the ratchet 542 teeth ensure that the ratchet 542 can only rotate in one direction. Reverse rotation is prevented by the ratchet teeth 544. This structure helps the drive structure 4 achieve unidirectional movement of the circular gear 3 530 when the teeth mesh. Furthermore, when the circular gear 3 530 meshes with the circular gear 1 230, the rotation direction of the winch 240 driven by the circular gear 1 230 is restricted, preventing damage to the drive structure 4. The winch 240 also stably compresses the cable core during formation, preventing the winch 240 from causing the cable core to rotate backward, thereby improving the stability and service life of the cable core formation. The above is the complete working principle of this utility model.
