A wire drawing device for power cord processing

Abstract

This utility model provides a wire drawing device for power cord processing, relating to the field of power cord processing technology. It includes a cooling and lubricating fluid tank, with support plates fixed to both sides of the top of the tank. A traction wheel is rotatably connected to one end of each support plate. A first motor drives a screw to rotate, causing a moving block to move under the constraint of a connecting block and a limiting post. This moves a second bracket located below the moving block, which in turn moves two mounting seats back and forth. As the mounting seats move, an infrared emitter at the top of the mold moves accordingly. When the infrared light emitted by the emitter aligns with the infrared receiver, the mounting seats stop moving entirely. At this point, the traction wheel, driving wheel, infrared receiver, infrared emitter, and the wire drawing opening inside the mold are all on the same horizontal line, preventing subsequent wrinkles and tilting of the power cord, thus enhancing stability.

Description

Technical Field

[0001] This utility model relates to the field of power cord processing technology, and in particular to a metal wire drawing device for power cord processing. Background Technology

[0002] In the power cord processing industry chain, metal wire drawing equipment is the core equipment for achieving precise forming of conductor metal wires. It undertakes the key task of transforming coarse-diameter metal billets into fine-diameter metal wires that meet the requirements of power cord conductivity and mechanical strength through continuous drawing process.

[0003] In a current power cord processing equipment, the wire drawing die used for drawing is in a fixed position. When the die is replaced or installed, the position will shift. The wire drawn by the traction wheel 3 will also shift due to the shift of the die, resulting in excessive friction or wrinkles on the outer wall of the wire, which affects the subsequent wire drawing process and has poor practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, the molds used for wire drawing are all in a fixed position. When the mold is replaced and installed, the position will shift. The metal wire pulled by the traction wheel 3 will also shift due to the shift of the mold, resulting in excessive friction or wrinkles on the outer wall of the metal wire, which affects the subsequent wire drawing process and has poor practicality. Therefore, this invention proposes a metal wire drawing device for power cord processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a metal wire drawing device for power cord processing, comprising a cooling lubricating fluid pool, with support plates fixed on both sides of the top of the cooling lubricating fluid pool, and traction wheels rotatably connected to one end of each of the two support plates. Drive wheels are rotatably connected to both ends of the inner wall of the cooling lubricating fluid pool. A first bracket is fixed to the rear end of the cooling lubricating fluid pool, and a connecting frame is fixed to the top of the first bracket. A movable block is provided inside the connecting frame, and an electric telescopic rod is installed at the bottom of the movable block. A second bracket is installed at the bottom of the electric telescopic rod, and mounting seats are fixed on both sides of the bottom of the second bracket. A mold is installed in each of the two mounting seats, with an infrared emitter installed at the top of one of the molds and an infrared receiver above one of the drive wheels. A drive structure for driving the movable block to move back and forth is provided inside the connecting frame.

[0006] Preferably, the drive structure includes a first motor mounted on one end of the connecting frame, the output end of the first motor passing through one side of the connecting frame and fixed with a screw, and connecting blocks fixed at both ends of the moving block, one of the connecting blocks being threadedly connected to the screw, and a limit post being slidably connected inside the other connecting block.

[0007] Preferably, the rear ends of the support plate and the cooling lubricant pool are both fixed with a fixing frame, and a second motor is installed in the fixing frame. The output end of the second motor passes through the corresponding cooling lubricant pool and support plate and is fixed to the traction wheel and drive wheel respectively.

[0008] Preferably, the traction wheel, drive wheel, infrared receiver, infrared transmitter, and wire pull opening in the mold are all on the same horizontal line, and a fourth bracket is fixed at the top of the cooling lubricant pool, with the infrared receiver installed at the top of the fourth bracket.

[0009] Preferably, the bottom end of the mold is fixed with a limiting block, the bottom end of the mounting base is provided with a limiting groove that matches the limiting block, the mounting base is provided with a pin, and the output end of the pin passes through the mounting base and the mold and is threadedly connected with a nut.

[0010] Preferably, the end of the screw furthest from the first motor is rotatably connected to the connecting frame, and both ends of the limiting post are fixed to the connecting frame.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the operation of the first motor drives the screw to rotate, causing the moving block to move under the combined control of the connecting block and the limiting post. This moves the second bracket located below the moving block, thereby causing the two mounting seats to move back and forth. When the mounting seats move back and forth, the infrared emitter at the top of the mold moves accordingly. When the infrared light emitted by the infrared emitter aligns with the infrared receiver, the mounting seats stop moving as a whole. At this point, the traction wheel, the driving wheel, the infrared receiver, the infrared emitter, and the wire pull opening inside the mold are all on the same horizontal line, preventing the subsequent power cord from becoming wrinkled or tilted, thus improving stability.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a metal wire drawing device for power cord processing, including a cooling lubricating liquid pool 1. Support plates 2 are fixed on both sides of the top of the cooling lubricating liquid pool 1. Traction wheels 3 are rotatably connected to one end of each support plate 2. Drive wheels 4 are rotatably connected to both ends of the inner wall of the cooling lubricating liquid pool 1. A first bracket 5 is fixed to the rear end of the cooling lubricating liquid pool 1. A connecting frame 6 is fixed to the top of the first bracket 5. A moving block 7 is provided inside the connecting frame 6. An electric telescopic rod 8 is installed at the bottom of the moving block 7. A second bracket 9 is installed at the bottom of the electric telescopic rod 8. Mounting seats 11 are fixed on both sides of the bottom of the second bracket 9. A mold 12 is installed inside each of the two mounting seats 11. An infrared transmitter 20 is installed at the top of one of the molds 12. An infrared receiver 22 is provided above one of the drive wheels 4. A drive structure 17 for driving the moving block 7 to move back and forth is provided inside the connecting frame 6.

[0021] The overall effect of Embodiment 1 is that, through the setting of the cooling lubricating fluid pool 1, when the drive wheel 4 rotates and pulls the metal wire, because the bottom end of the drive wheel 4 is located in the cooling lubricating fluid in the cooling lubricating fluid pool 1, the metal wire is also immersed in the cooling lubricating fluid, avoiding the generation of a large amount of heat from subsequent friction. The metal wire passes through the mold 12 and is squeezed through the wire drawing opening of the mold 12, so that it becomes a suitable thickness when it leaves the mold 12. Moreover, the device has two molds 12, and the wire drawing openings of the two molds 12 are different. The power wire can be initially thinned through the first mold 12, and then precisely thinned through the other mold 12, avoiding the power wire being too thick and suddenly becoming thinner, which could cause breakage. The system exhibits enhanced stability by mitigating cracking. The drive structure 17 moves the moving block 7 vertically, which in turn moves the molds 12 installed in the two mounting bases 11 vertically. The electric telescopic rod 8 then raises and lowers the molds 12. The infrared emitter 20 at the top of the mold 12 moves accordingly. When the infrared light emitted by the emitter 20 aligns with the infrared receiver 22, the mounting base 11 stops moving. At this point, the traction wheel 3, drive wheel 4, infrared receiver 22, infrared emitter 20, and the cable pull opening in the mold 12 are all on the same horizontal line, preventing subsequent wrinkles and tilting of the power cable, thus enhancing stability.

[0022] Example 2, as Figure 1-4 As shown, the drive structure 17 includes a first motor 1701 mounted on one end of the connecting frame 6. The output end of the first motor 1701 passes through one side of the connecting frame 6 and is fixed with a screw 1702. Both ends of the moving block 7 are fixed with connecting blocks 1703. One connecting block 1703 is threadedly connected to the screw 1702, and the other connecting block 1703 is slidably connected with a limit post 1704. The rear ends of the support plate 2 and the cooling lubricating fluid pool 1 are both fixed with a fixing frame 18. A second motor 19 is installed in the fixing frame 18. The output end of the second motor 19 passes through the corresponding cooling lubricating fluid pool 1 and support plate 2 and is fixed to the traction wheel 3 and the driving wheel 4 respectively. The drive wheel 4, infrared receiver 22, infrared transmitter 20 and the wire pull port in the mold 12 are all on the same horizontal line. The top of the cooling lubricant pool 1 is fixed with a fourth bracket 21. The infrared receiver 22 is installed on the top of the fourth bracket 21. The bottom of the mold 12 is fixed with a limit block 13. The bottom of the mounting base 11 is provided with a limit groove 14 that matches the limit block 13. The mounting base 11 is provided with a pin 15. The output end of the pin 15 passes through the mounting base 11 and the mold 12 and is threadedly connected with a nut 16. The end of the screw 1702 away from the first motor 1701 is rotatably connected to the connecting frame 6. Both ends of the limit post 1704 are fixed to the connecting frame 6.

[0023] The overall effect of Embodiment 2 is as follows: the operation of the first motor 1701 drives the screw 1702 to rotate, causing the moving block 7 to move under the limiting action of the connecting block 1703 and the limiting post 1704. This causes the second bracket 9 located below the moving block 7 to move, thereby causing the two mounting seats 11 to move back and forth. The setting of the limiting block 13 and the limiting groove 14 can limit the installation of the mold 12, preventing it from being installed at an angle in the mounting seat 11. The setting of the pin 15 and the nut 16 allows the mold 12 to be replaced. The operation of the second motor 19 can drive the traction wheel 3 and the driving wheel 4 to rotate, enabling the traction transmission of the power cord. The first motor 1701, the second motor 19, the infrared transmitter 20, and the infrared receiver 22 of this device are all controlled by an external controller.

[0024] Working principle: When this device is in use, the rotating drive wheel 4 pulls the metal wire through the cooling lubricant pool 1. Since the bottom of the drive wheel 4 is immersed in the cooling lubricant in the pool 1, the metal wire is also submerged, preventing excessive heat from subsequent friction. The metal wire passes through the mold 12 and is compressed through its drawing opening, resulting in a suitable thickness when it exits the mold 12. The device has two molds 12 with different drawing openings. The power wire can be initially thinned through the first mold 12 and then precisely thinned through the second mold 12, preventing breakage due to sudden thinning caused by an excessively thick wire. The operation of the first motor 1701 drives the screw 170... 2. Rotate to move the moving block 7 under the limiting of the connecting block 1703 and the limiting post 1704, which drives the second bracket 9 below the moving block 7 to move, thereby driving the two mounting seats 11 to move back and forth. When the mounting seats 11 move back and forth, the infrared emitter 20 at the top of the mold 12 will move accordingly. When the infrared light emitted by the infrared emitter 20 aligns with the infrared receiver 22, the mounting seat 11 stops moving as a whole. At this time, the traction wheel 3, the driving wheel 4, the infrared receiver 22, the infrared emitter 20 and the wire pull port in the mold 12 are all on the same horizontal line, avoiding the phenomenon of subsequent power lines being wrinkled or tilted, and the stability is stronger. With the two traction wheels 3, the power line is introduced into one traction wheel 3 and exited from the other traction wheel 3.

[0025] The wiring diagrams of the first motor 1701, the second motor 19, the infrared transmitter 20, and the infrared receiver 22 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring arrangements of the first motor 1701, the second motor 19, the infrared transmitter 20, and the infrared receiver 22 will not be explained in detail.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
