Description

Technical Field

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

[0002] The cable core cold drawing machine uses a mold to apply tension to the cable core, causing it to undergo plastic deformation at room temperature as it passes through the mold holes or the gap between rollers. This reduces the core diameter and improves the surface quality of the core. During the cold drawing process, the cable core is subjected to tensile and compressive forces, which changes the microstructure of the metal material. The grains are elongated and refined, thereby improving the strength and hardness of the core.

[0003] In the prior art, when a cold drawing machine performs cold drawing on cable cores, in order to reduce the coefficient of friction between the cable core and the contact surface, an oil groove is usually set at the end of the cold drawing machine. The operator manually applies lubricating oil to the cable core. However, the force and thickness of the manual application of lubricating oil are uneven, resulting in insufficient or excessive lubrication in some areas, and the application speed is slow. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a cable core cold drawing machine, which solves the problems mentioned in the background art, such as the need for workers to manually apply lubricating oil to the cable core during the use of the cold drawing machine, which easily leads to uneven force and thickness, resulting in local insufficient or excessive lubrication, and the application speed is slow.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A cable core cold drawing machine, comprising:

[0007] A cable cold drawing machine, wherein the cable cold drawing machine is equipped with a cold drawing clamp, and the cable cold drawing machine has a wire drawing hole and an oil storage tank; characterized in that it further includes:

[0008] The oil-drip structure is arranged on the cable cold drawing machine and is used to drip oil onto the surface of the cable core.

[0009] An oil-brushing structure, arranged on top of an oil-drip structure, is used to apply dripping oil to the surface of the cable core.

[0010] An adjustment structure, arranged on the dripping oil structure, is used to adjust the height and position of the dripping oil structure and the brushing oil structure.

[0051] 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.

[0052] Example 1:

[0053] like Figures 1 to 6 As shown, this utility model provides a cable core cold drawing machine, including: a cable cold drawing machine 1 and a cold drawing clamp 103 arranged on the cable cold drawing machine 1. The cable cold drawing machine 1 is provided with a wire drawing hole 101 and an oil storage tank 102. It also includes an oil dripping structure arranged on the cable cold drawing machine 1 for dripping oil onto the surface of the cable core.

[0054] The oil dripping structure includes an L-shaped mounting bracket 2 detachably mounted on the cable cold drawing machine 1, a movable frame 201 slidably mounted on one side of the L-shaped mounting bracket 2, a suction pump 202 arranged above the movable frame 201, a diversion pipe 203 arranged on the delivery end of the suction pump 202, several dripping pipes 204 evenly arranged on and connected to the diversion pipe 203, a suction pipe 205 arranged on the suction end of the suction pump 202, and a corrugated pipe arranged at one end of the suction pipe 205 and located in the oil storage tank 102. Pipe 206, when the suction pump 202 is turned on, can use the suction pipe 205 and the bellows 206 to draw lubricating oil from the oil reservoir 102, and then drip it onto the surface of the cable core through the dropper 204 on the diversion pipe 203. The bellows 206 can be stretched so that the length of the bellows 206 can be adjusted according to the remaining amount of lubricating oil in the oil reservoir 102 or the depth of the oil reservoir 102, ensuring that the bellows 206 can always be in contact with the lubricating oil. A metal spiral skeleton can be set inside the bellows 206 so that it can be shaped after stretching.

[0055] Example 2:

[0056] Based on Example 1, in order to ensure that the lubricating oil is evenly covered on the surface of the cable core, an oil-brushing structure is arranged on the oil-drip structure to apply the dripping oil to the surface of the cable core.

[0057] The oiling structure includes a rotating ring 3 rotatably mounted inside the movable frame 201 and located on the same axis as the cable pulling hole 101, several connecting frames 301 evenly arranged on one side of the rotating ring 3, a guide rod 302 slidably mounted inside the connecting frame 301, a wheel frame 303 arranged at one end of the guide rod 302, a coating roller 304 rotatably mounted inside the wheel frame 303, a drive assembly arranged on the rotating ring 3 for controlling the rotation of the rotating ring 3, and an elastic assembly arranged on the wheel frame 303 for making the coating roller 304 fit against the cable core. The drive assembly can control the rotation of the rotating ring 3. The continuously rotating rotating ring 3 can drive the connecting frame 301, the guide rod 302, and the wheel frame 303 to rotate, thereby driving the coating roller 304 to perform circumferential motion around the cable core, and evenly applying the dripping lubricating oil to the surface of the cable core.

[0058] Specifically, the drive assembly includes a gear ring 305 fixedly sleeved on the rotating ring 3, a reduction motor 306 arranged on one side of the movable frame 201, and a linkage gear 307 arranged on the output end of the reduction motor 306 and meshing with the gear ring 305. Turning on the reduction motor 306 can drive the linkage gear 307 to rotate. When the linkage gear 307 rotates, it can drive the rotating ring 3 to rotate inside the movable frame 201 through meshing with the gear ring 305.

[0059] Specifically, the elastic component includes a spring 308 arranged on one side of the wheel frame 303. One end of the spring 308 is arranged on the connecting frame 301. Under the elastic force of the spring 308, the wheel frame 303 is squeezed and causes the guide rod 302 to slide within the connecting frame 301. At the same time, the wheel frame 303 causes the coating roller 304 to move towards the cable core, thereby enabling the coating roller 304 to fit against the cable core.

[0060] The oiling structure also includes a baffle 309 arranged at one end of the guide rod 302 to prevent the guide rod 302 from detaching from the connecting frame 301. The baffle 309 can prevent the wheel frame 303 and the brushing roller 304 from falling off the connecting frame 301.

[0061] Example 3:

[0062] Based on Example 1, in order to enable the device to be installed on cable cold drawing machines 1 of different specifications for use, an adjustment structure for adjusting the height position of the oil dripping structure and the oil brushing structure is arranged on the oil dripping structure.

[0063] The adjustment structure includes an adjusting screw 4 arranged above the movable frame 201 and slidably installed inside the L-shaped mounting bracket 2; two nuts 401 threaded onto the adjusting screw 4 and in contact with both sides of the L-shaped mounting bracket 2; a guide groove 402 opened inside the movable frame 201; and a guide bar 403 arranged on one side of the L-shaped mounting bracket 2 and slidably installed inside the guide groove 402. By rotating the nuts 401 on both sides and releasing them from the pressure on the L-shaped mounting bracket 2, the height of the movable frame 201 and the rotating ring 3 can be adjusted. When the movable frame 201 moves, it can slide on the guide bar 403 through the guide groove 402. The arrangement of the guide groove 402 and the guide bar 403 can restrict the vertical movement of the movable frame 201 so that when used on the cable cold drawing machine 1 of different specifications, the height of the rotating ring 3 can be adjusted so that it is on the same axis as the wire drawing hole 101 for use.

[0064] The adjustment structure also includes several mounting screws 404 that pass through the L-shaped mounting bracket 2 and are threaded inside the cable cold drawing machine 1 to fix the position of the L-shaped mounting bracket 2. By rotating and unscrewing the mounting screws 404, the L-shaped mounting bracket 2 can be removed from the cable cold drawing machine 1 so that it can be disassembled and reassembled as needed.

[0065] Working principle: During the cold drawing of the cable core, it is passed between several coating rollers 304. By turning on the suction pump 202, the pump uses the suction pipe 205 and the bellows 206 to draw lubricating oil from the oil storage tank 102. Then, the oil drips onto the surface of the cable core through the drip pipe 204 on the diversion pipe 203. Excess oil drips back into the oil storage tank 102. Then, turning on the reduction motor 306 drives the linkage gear 307 to rotate. When the linkage gear 307 rotates, it can drive the rotating ring 3 to move through the meshing with the gear ring 305. The internal rotation of the frame 201 and the continuously rotating ring 3 can drive the connecting frame 301 to move in a circular motion. The connecting frame 301 uses the guide rod 302 and the wheel frame 303 to drive the coating roller 304 to move in a circular motion around the cable core. Under the elastic force of the spring 308, the wheel frame 303 will be squeezed and the coating roller 304 will be put into contact with the cable core. At the same time, it can be adapted to cable cores of different sizes. Then, under the continuous movement of the coating roller 304, the dripping lubricating oil can be evenly applied to the surface of the cable core so that it can be fully lubricated.

[0066] The L-shaped mounting bracket 2 can be removed from the cable cold drawing machine 1 by rotating and unscrewing the mounting screw 404, allowing for selective disassembly and assembly as needed. After installation, the nuts 401 on both sides can be rotated to move the nuts 401 on the adjusting screw 4 and release them from the pressure on the L-shaped mounting bracket 2, thus relieving the positional restriction on the adjusting screw 4 and the movable bracket 201. Pulling the adjusting screw 4 will then move the movable bracket 201, thereby adjusting the height of the movable bracket 201 and the rotating ring 3. This allows for adjustment of the height of the rotating ring 3 when used on different specifications of cable cold drawing machines 1, ensuring it is aligned with the wire drawing hole 101. After adjustment, the nuts 401 on both sides can be rotated in the opposite direction to re-press the nuts 401 onto both sides of the L-shaped mounting bracket 2, thus restricting the height of the adjusting screw 4 and the movable bracket 201. Washers can also be added between the nuts 401 and the L-shaped mounting bracket 2 to increase friction and stability.

[0067] 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.
