Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a cable drawing position regulating device. Background Art

[0002] Wire drawing is a core technology in cable manufacturing. It involves drawing metal materials such as copper and aluminum through a wire drawing machine into fine filaments of various specifications for use in the manufacture of electronic products such as wires and cables. During the drawing process, the wire stock undergoes plastic deformation as it passes through a die under tension, reducing its cross-section and increasing its length, resulting in a precisely sized, smooth-surfaced wire.

[0003] Existing wire drawing machines generally adjust the tightness of the overall tension when adjusting cable drawing. Since it is impossible to fine-tune the local tension, the cable may be stretched unevenly during the drawing process, which will cause significant differences in the cable's physical properties such as diameter and strength in different parts, thereby affecting the overall quality and performance stability of the cable.

[0004] The purpose of the present invention is to provide a cable drawing position adjustment device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides a cable drawing position adjustment device, including a drawing machine body, a mounting frame, and a drawing wheel. The drawing machine body is provided with a stretching mechanism, and the stretching mechanism includes a dual-axis motor, one side of the dual-axis motor is rotatably connected to a first screw rod, a first transmission belt is connected to the lower driving end of the dual-axis motor and the first screw rod, the other side of the dual-axis motor is rotatably connected to a second screw rod, a second transmission belt is connected to the upper driving end of the dual-axis motor and the second screw rod, the mounting frame is threadedly connected to the outer walls of the first screw rod and the second screw rod, and the drawing wheel is rotatably connected to the mounting frame.

[0006] Furthermore, a plurality of guide rods are fixedly mounted on the inner wall of the wire drawing machine body, and the mounting bracket is slidably connected to the outer wall of the guide rods.

[0007] Furthermore, an L-shaped support block and an L-shaped support block are fixedly installed on the top of the wire drawing machine body, the first screw rod is rotatably connected to the inner top wall of the L-shaped support block, and the second screw rod is rotatably connected to the inner top wall of the L-shaped support block.

[0008] Furthermore, an L-shaped block is fixedly mounted on the top wall of the wire drawing machine body, and the L-shaped block is fixedly mounted on the outer wall of the dual-axis motor.

[0009] Furthermore, the outer wall of the drawing wheel is provided with a cable body, and the outer walls of the first screw rod and the second screw rod are both fixedly mounted with transmission wheels.

[0010] Furthermore, the mounting bracket and the second screw rod are both made of iron.

[0011] Furthermore, a C-shaped mounting block is provided on the outer wall of the drawing wheel, a sub-velcro is fixedly mounted on the outer wall of the drawing wheel, and a mother Velcro that matches the sub-velcro is fixedly mounted on the inner wall of the C-shaped mounting block.

[0012] Furthermore, a first magnet is fixedly mounted on the C-shaped mounting block, and a second magnet is fixedly mounted on a side of the C-shaped mounting block opposite to the first magnet.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this utility model, a single-chip microcomputer is used to control the driving end of the dual-axis motor, and the transmission belt is used to drive the screw to rotate, so as to realize the lifting and lowering of the mounting frame and the drawing wheel, and then adjust the tension of the cable body.

[0024] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0026] See Figure 1-Figure 5 The present invention shows a cable drawing position adjustment device, comprising a drawing machine body 1, a mounting frame 3, and a drawing wheel 4. The drawing machine body 1 is provided with a stretching mechanism 2, and the stretching mechanism 2 comprises a dual-axis motor 201, one side of the dual-axis motor 201 is rotatably connected to a first screw rod 203, a first transmission belt 202 is connected to the lower driving end of the dual-axis motor 201 and the first screw rod 203, the other side of the dual-axis motor 201 is rotatably connected to a second screw rod 205, a second transmission belt 204 is connected to the upper driving end of the dual-axis motor 201 and the second screw rod 205, the mounting frame 3 is threadedly connected to the outer walls of the first screw rod 203 and the second screw rod 205, and the drawing wheel 4 is rotatably connected to the mounting frame 3.

[0027] The single-chip microcomputer is used to control the start of the upper driving end of the dual-axis motor 201. The upper driving end of the dual-axis motor 201 drives the second screw rod 205 to rotate through the second transmission belt 204, so that the mounting bracket 3 on the second screw rod 205 moves toward the direction of the L-shaped support block 14, so that the mounting bracket 3 and the drawing wheel 4 drive the cable body 1 below the second screw rod 205 to tighten. The lower driving end of the dual-axis motor 201 is controlled to rotate. The lower driving end of the dual-axis motor 201 drives the first screw rod 203 to rotate through the first transmission belt 202, so that the mounting bracket 3 on the first screw rod 203 moves upward to tighten the cable body 13 below the first screw rod 203. The above is to adjust the tension of the cable body 13 locally.

[0028] Similarly, the upper and lower drive ends of the two dual-axis motors 201 can be activated simultaneously to synchronize the rotation of the first and second transmission belts 202 and 204, thereby activating the mounting frame 3 and the drawing wheel 4 for synchronous lifting and lowering, thereby adjusting the overall tension of the cable body 13. By precisely controlling the local tension of the cable body 13, over- or under-stretching can be avoided during the drawing process, ensuring that the quality and performance of the cable body 13 meet standard requirements. Furthermore, adjusting the overall tension helps maintain the stability and consistency of the cable body 13 throughout the production process.

[0029] See Figure 5 A plurality of guide rods 10 are fixedly mounted on the inner wall of the wire drawing machine body 1 , and the mounting frame 3 is slidably connected to the outer wall of the guide rod 10 .

[0030] The guide rod 10 provides guidance for the mounting frame, ensuring that the mounting frame 3 can remain stable when moving or adjusting, reducing shaking and vibration, and at the same time preventing the mounting frame 3 from rotating when the first screw rod 203 and the second screw rod 205 are rotating. This is important for maintaining the stability of the wire drawing process and helps to improve product quality and production efficiency.

[0031] See Figure 1 An L-shaped support block 12 and an L-shaped support block 14 are fixedly installed on the top of the wire drawing machine body 1. The first screw rod 203 is rotatably connected to the inner top wall of the L-shaped support block 12, and the second screw rod 205 is rotatably connected to the inner top wall of the L-shaped support block 14.

[0032] The L-shaped support block 12 and the L-shaped support block 14 provide stable support for the first screw rod 203 and the second screw rod 205, ensuring that the screw rods are not prone to shaking or shifting during operation. This stable support structure helps to maintain the stability and continuity of the wire drawing process and improve product quality and production efficiency.

[0033] See Figure 1 An L-shaped block 11 is fixedly mounted on the top wall of the wire drawing machine body 1 , and the L-shaped block 11 is fixedly mounted on the outer wall of the dual-axis motor 201 .

[0034] The L-shaped block 11 serves as a connecting piece to firmly fix the dual-axis motor 201 on the top wall of the wire drawing machine body 1. This fixing method can ensure that the motor will not shake or shift during operation.

[0035] See Figure 1 The outer wall of the drawing wheel 4 is provided with a cable body 13, and the outer walls of the first screw rod 203 and the second screw rod 205 are fixedly mounted with transmission wheels.

[0036] The transmission wheels on the first and second screw rods 203 and 205 ensure stable power transmission. The transmission wheels, in conjunction with the first and second transmission belts 202 and 204, effectively transmit power from the dual-axis motor 201 to the screw rods, thereby rotating the wire drawing wheels 4. This reduces energy loss during power transmission and improves the operating efficiency of the entire wire drawing machine body 1.

[0037] See Figure 1 The materials of the mounting bracket 3 and the second screw rod 205 are both iron.

[0038] Iron is a material with high strength and good durability. Using iron ensures that the mounting frame 3 has sufficient load-bearing capacity and stability to withstand the various forces and vibrations during the operation of the wire drawing machine body 1. The mounting frame 3 and second screw rod 205 made of iron also ensure sufficient strength and durability when rotating and bearing tension.

[0039] See Figure 2-3 A C-shaped mounting block 5 is provided on the outer wall of the drawing wheel 4, a sub-Velcro 6 is fixedly installed on the outer wall of the drawing wheel 4, and a female Velcro 7 adapted to the sub-Velcro 6 is fixedly installed on the inner wall of the C-shaped mounting block 5.

[0040] The diameter of the cable body 13 directly determines the workload and stretching effect of the drawing wheel 4. A thicker cable body 13 requires a larger diameter of the drawing wheel 4 to provide sufficient support and stretching force. Through the cooperation of the sub-velcro 6 and the mother Velcro 7, the thicker C-shaped mounting block 5 can be fixedly installed on the outer wall of the drawing wheel 4. A thinner cable body 13 may require a smaller diameter of the drawing wheel 4 to avoid excessive stretching or damage. Therefore, the C-shaped mounting block 5 outside the drawing wheel 4 can be replaced with another C-shaped mounting block 5 with a relatively low thickness. Matching the appropriate diameter of the drawing wheel 4 can ensure that the cable body 13 is evenly stressed during the stretching process and avoid the occurrence of excessive or insufficient local stress. The C-shaped mounting block 5 has a certain elastic force and can be slightly opened and then put on the outer wall of the drawing wheel 4.

[0041] See Figure 3 A first magnet 8 is fixedly mounted on the C-shaped mounting block 5 , and a second magnet 9 is fixedly mounted on a side of the C-shaped mounting block 5 opposite to the first magnet 8 .

[0042] The first magnet 8 and the second magnet 9 attract each other through magnetic force, which helps to enhance the overall stability of the C-shaped mounting block 5. The magnetic connection has the characteristic of self-positioning, which enables the C-shaped mounting block 5 to maintain a stable position when subjected to external forces or vibrations, reducing the possibility of loosening or displacement.

[0043] Working principle: The upper driving end of the dual-axis motor 201 is controlled by a single-chip microcomputer to start, and the upper driving end of the dual-axis motor 201 drives the second screw rod 205 to rotate through the second transmission belt 204, so that the mounting bracket 3 on the second screw rod 205 moves toward the L-shaped support block 14, so that the mounting bracket 3 and the drawing wheel 4 drive the cable body 13 below the second screw rod 205 to tighten. The lower driving end of the dual-axis motor 201 is controlled to rotate, and the lower driving end of the dual-axis motor 201 drives the first screw rod 203 to rotate through the first transmission belt 202, so that the mounting bracket 3 on the first screw rod 203 moves upward, which can tighten the cable body 13 below the first screw rod 203. The above is to adjust the tension of the cable body 13 locally.

[0044] Similarly, the upper and lower drive ends of the two dual-axis motors 201 can be activated simultaneously to synchronize the rotation of the first and second transmission belts 202 and 204, thereby activating the mounting frame 3 and the drawing wheel 4 for synchronous lifting and lowering, thereby adjusting the overall tension of the cable body 13. By precisely controlling the local tension of the cable body 13, over- or under-stretching can be avoided during the drawing process, ensuring that the quality and performance of the cable body 13 meet standard requirements. Furthermore, adjusting the overall tension helps maintain the stability and consistency of the cable body 13 throughout the production process.

[0045] The diameter of the cable body 13 directly determines the workload and stretching effect of the drawing wheel 4. A thicker cable body 13 requires a larger diameter of the drawing wheel 4 to provide sufficient support and stretching force. Through the cooperation of the sub-velcro 6 and the mother Velcro 7, the thicker C-shaped mounting block 5 can be fixedly installed on the outer wall of the drawing wheel 4. A thinner cable body 13 may require a smaller diameter of the drawing wheel 4 to avoid excessive stretching or damage. Therefore, the C-shaped mounting block 5 outside the drawing wheel 4 can be replaced with another C-shaped mounting block 5 with a relatively low thickness. Matching the appropriate diameter of the drawing wheel 4 can ensure that the cable body 13 is evenly stressed during the stretching process and avoid the occurrence of excessive or insufficient local stress. The C-shaped mounting block 5 has a certain elastic force and can be slightly opened and then put on the outer wall of the drawing wheel 4.
