Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cable metal wire processing equipment, specifically, to a wire and cable metal wire drawing and thinning processing equipment. Background Technology
[0002] In the production process of wires and cables, the wire drawing process is a crucial step that determines the product specifications and performance. The performance of the wire drawing equipment directly affects the quality and production efficiency of wires and cables. The wire drawing equipment usually uses a corresponding extrusion drawing wheel. The cable wire passes through the extrusion drawing wheel and, as the extrusion drawing wheel rotates, it can convey the cable wire forward and complete the extrusion drawing effect.
[0003] However, currently available wire and cable wire thinning devices still have some problems in use. For example, most wire thinning devices directly pass the cable wire through extrusion drawing wheels, relying on the rigid contact of the wheels to complete the thinning process. This process lacks a component that can properly heat the cable wire. Since the deformation of the cable wire is directly related to its temperature, directly thinning and extruding unheated cable wire presents significant challenges. Furthermore, during the thinning process, the small deformation and high rigidity and brittleness of the cable wire can lead to breakage, hindering stable processing. Therefore, we propose a wire and cable wire thinning device. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0027] Please see Figures 1-3This utility model provides a technical solution: a wire and cable wire drawing and thinning processing device, including a support panel 1 fixedly installed on an external frame. A first support frame 10 and a second support frame 11 are respectively fixedly installed on the left and right sides of the support panel 1. The first support frame 10 is provided with a limiting wheel 13 for limiting the left and right position of the cable wire. A conveying gap 131 is provided in the limiting wheel 13. The two discs on both sides of the limiting wheel 13 are used to limit the left and right position of the cable wire. The second support frame 11 is provided with a pressing and drawing wheel 15 for pressing and thinning the cable wire, so that the cable wire is always kept on the predetermined path during the processing, effectively preventing the wire from deviating, and ensuring that the pressing and drawing wheel 15 can accurately press and thin the wire, thereby improving the processing accuracy and product quality.
[0028] In this embodiment, both the limiting wheel 13 and the extrusion drawing wheel 15 are driven by the corresponding servo motor 17. The extrusion drawing wheel 15 is provided with an extrusion gap 151. The size of the multiple extrusion gaps 151 decreases sequentially from front to back. With the drive of the servo motor 17, the cable metal wire can be gradually extruded and drawn thin according to production needs, and metal wires of different sizes can be processed to meet diverse production requirements and improve the applicability of the device.
[0029] Specifically, a rectangular frame 2 is provided between the first support frame 10 and the second support frame 11. Multiple horizontally arranged heat-insulating pipes 21 are mounted on the rectangular frame 2. A temperature-controlled electric heating wire 24 is detachably installed inside each heat-insulating pipe 21. The temperature-controlled electric heating wire 24 is spiral-shaped, and the cable wire passes through it, ensuring that the cable wire is uniformly heated before entering the extrusion drawing wheel 15. Since the wire temperature is related to its deformation, the heated wire is easier to draw into thinner pieces, reducing processing difficulty, decreasing wire breakage, and improving processing efficiency and yield.
[0030] Furthermore, the left and right side plates of the first support frame 10 are rotatably connected by two symmetrical first rotating shafts 12, and multiple limiting wheels 13 are symmetrically installed on the two first rotating shafts 12. The left and right side plates of the second support frame 11 are rotatably connected by two symmetrical second rotating shafts 14, and multiple extrusion and drawing wheels 15 are symmetrically installed on the two second rotating shafts 14. Gears 16 are fixedly installed at the ends of the first rotating shafts 12 and the second rotating shafts 14, and the two gears 16 mesh with each other. The servo motor 17 is coaxially set at the ends of the corresponding first rotating shaft 12 and the corresponding second rotating shaft 14 to realize the normal extrusion and drawing operation of cable metal wires.
[0031] It is worth noting that the position of the limiting wheel 13 corresponds to the position of the extrusion drawing wheel 15, so that the limiting wheel 13 can guide and prevent the cable metal wire from deviating, and the extrusion drawing wheel 15 can perform extrusion drawing operations normally.
[0032] like Figure 1 and Figure 2 As shown, fixed bases 18 are fixedly installed on both sides of the first support frame 10 and the second support frame 11. The fixed bases 18 are detachably installed on the support panel 1 by multiple fastening bolts, which facilitates the installation, disassembly and maintenance of the entire processing device. When it is necessary to inspect or adjust the position of the device, it can be operated quickly, reducing downtime and improving production flexibility.
[0033] It is worth noting that a central plate 20 is fixedly installed between the left and right side plates of the rectangular frame 2. The end of the insulation pipe 21 is fixedly installed on the central plate 20. An end ring 22 is fixedly installed on the inner wall of the front end of the insulation pipe 21. A fixing ring 23 is fixedly installed on the end of the temperature-controlled electric heating wire 24. The fixing ring 23 is detachably installed on the front side of the end ring 22 by multiple fastening screws. A wire hole 231 is provided at the center of the fixing ring 23, which facilitates timely replacement of damaged or degraded temperature-controlled electric heating wire 24 according to usage conditions, ensuring stable heating effect on the metal wire. It also facilitates the replacement of temperature-controlled electric heating wire 24 of different specifications according to different metal wire processing requirements, enhancing the practicality and maintainability of the device.
[0034] Finally, it should be noted that the servo motor 17 and temperature-controlled electric heating wire 24 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.
[0035] When using the wire and cable metal wire drawing and refining device of this utility model, firstly, the first support frame 10 and the second support frame 11 are installed on the support panel 1 by fastening bolts on the fixed base 18, and then the support panel 1 is fixed to the external frame to complete the basic installation of the device.
[0036] The cable wire passes through the conveying gap 131 of the limiting wheel 13. The limiting wheel 13 uses the discs on both sides to limit the wire to the left and right. Then the wire passes through the temperature-controlled electric heating wire 24 in the heat insulation tube 21 on the rectangular frame 2. The heated wire enters the extrusion gap 151 of the extrusion drawing wheel 15. The servo motor 17 is started, which drives the second rotating shaft 14 to rotate. Since the gears 16 at the end of the second rotating shaft 14 mesh with each other, the extrusion drawing wheel 15 rotates synchronously. The extrusion drawing wheel 15 extrudes and draws the cable wire to complete the drawing process.
[0037] When the temperature-controlled electric heating wire 24 malfunctions or needs to be replaced, it can be disassembled and replaced by unscrewing the fastening screw between the fixing ring 23 and the end ring 22.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
