Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire and cable production technology, specifically relating to a wire and cable drawing device. Background Technology
[0002] Wire drawing equipment is a key piece of equipment in metal wire processing. It is mainly used to stretch metal billets (such as copper, aluminum, and steel) through dies to reduce their diameter and form uniform wires to meet the specifications required for wire and cable production. The wire drawing process typically includes unwinding, pickling / coating, initial drawing, annealing, multiple drawing passes, online inspection, and winding. Among these steps, cooling is performed after annealing to control the microstructure, eliminate residual stress, and optimize mechanical properties.
[0003] Chinese patent document CN222359019U discloses a wire and cable drawing device. After the wire is annealed, the wire being transported around the rotating rod is cooled by injecting an appropriate amount of coolant that can overflow the rotating rod into the cooling box of the cooling mechanism.
[0004] However, in existing technologies, when cooling wires by immersion, the central area of the wire is prone to slow cooling due to sluggish heat conduction, resulting in a large temperature difference between the inside and outside of the wire. In addition, spray cooling is also widely used, but when the nozzle angle, pressure, or distribution is unreasonable, the coolant cannot evenly cover the wire surface, easily leading to localized overheating. Therefore, a wire and cable drawing device is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a wire and cable drawing device.
[0006] The technical solution adopted in this utility model is as follows:

[0013] Preferably, the retaining ring, the plug, and the inner surface of the liquid guiding cavity are all integrally formed with a flow guiding groove, and the liquid guiding cavity has a hollow structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0030] like Figures 1-7 As shown, a wire and cable drawing device includes a drawing device body 1 that can process metal blanks through multiple processes. An inspection cover 2 is provided in front of the drawing device body 1 so that the operator can inspect each process. Wires 3 that have undergone the drawing process are threaded inside the drawing device body 1.
[0031] In this embodiment: the wire drawing device body 1 includes a cooling host 101, a drain pipe 104 is fixedly connected to the rear of the cooling host 101, a cooling component 4 is fixedly installed inside the cooling host 101, the wire drawing device body 1 also includes an annealing host 102 disposed on one side of the cooling host 101, a wire drawing host 103 disposed on one side of the annealing host 102, and an inspection cover 2 is movably installed in front of the cooling host 101, the annealing host 102, and the wire drawing host 103, and the wire 3 passes through the cooling host 101, the annealing host 102, and the wire drawing host 103 in sequence;
[0032] The cooling host 101 provides an installation position for the cooling component 4. The annealing host 102 anneales the wire 3 that has traveled from the drawing host 103 to eliminate work hardening and restore the ductility of the wire 3. The drawing host 103, which has a built-in multi-stage mold, gradually compresses the wire 3 passing through it to reduce the cross-section of the wire 3 and thus reduce the diameter of the wire 3. The annealing host 102 and the drawing host 103 are both mature existing technologies in this field, so they will not be described in detail. The drain pipe 104 is connected to the return end of a coolant circulation device with a filtration function to discharge the coolant contained in the cooling host 101, so that the coolant can be purified and cooled during continuous flow. The inspection cover 2 allows the operator to easily observe the drawing status of the wire 3 in this device, or to maintain or repair the vulnerable parts of the cooling host 101, annealing host 102, and drawing host 103.
[0033] In this embodiment: the cooling component 4 includes a spraying component that can spray and cool the wire 3 passing through the cooling host 101 in multiple directions, a transmission component that can make the spraying component swing around the wire 3 when it travels, and a liquid supply component that can introduce the coolant supplied to the cooling host 101 into the spraying component.
[0034] The spray system includes two brackets 401 fixedly installed inside the cooling host 101. Each bracket 401 has a retaining ring 402 movably installed within it. Two plugs 403 are fixedly connected to the side of one retaining ring 402 closest to the other. A liquid guiding chamber 404 is provided between the plugs 403 of the same height. Multiple atomizing nozzles 405 are fixedly connected to the inner side of the liquid guiding chamber 404. The transmission system includes a bearing 406 fixedly installed inside the brackets 401. A rotating shaft 407 is movably connected between the two bearings 406. One end of the rotating shaft 407... A cam 408 is fixedly connected, and a connecting rod 409 is provided between the adjacent retaining ring 402 and the cam 408. A worm gear 410 is fixedly connected to the other end of the rotating shaft 407. A support 411 is provided on one side of the bracket 401 adjacent to the worm gear 410. A worm 412 is movably connected below the support 411. A roller 413 is provided between the wire 3 and the lower end of the worm 412. The liquid supply component includes a liquid injection connector 414 fixedly installed behind the cooling host 101. A hose 415 is provided between the liquid guiding chamber 404 and the liquid injection connector 414.
[0035] The inner surfaces of the retaining ring 402, the plug 403, and the liquid guiding cavity 404 are all integrally formed with flow guiding grooves. The liquid guiding cavity 404 has a hollow structure. The bracket 401 is rotatably connected to the retaining ring 402. The bearing seat 406 is rotatably connected to the rotating shaft 407. The cam 408 and the retaining ring 402 connected to the connecting rod 409 are rotatably connected to the connecting rod 409. The support 411 is rotatably connected to the worm 412. The worm wheel 410 is meshed with the worm 412.
[0036] The bracket 401 provides mounting positions for components such as the retaining ring 402 and the shaft seat 406. Through its connection with the cooling host 101, these components can be stably installed within the cooling host 101. The retaining ring 402, which can rotate relative to the bracket 401, provides mounting positions for the plugs 403 that can seal both ends of the liquid guiding cavity 404. When the plugs 403 are inserted into their ends, the liquid guiding cavity 404 can rotate relative to the bracket 401 together with the plugs 403 and the retaining ring 402 under external force. Multiple atomizing nozzles 405 mounted on the liquid guiding cavity 404 evenly spray the coolant injected into the liquid guiding cavity 404 onto different positions of the wire 3. The guide groove allows the coolant to easily flow out from the spray nozzle after contacting the wire 3, and through the shaft seat 406... 06 The rotating shaft 407 is installed between two brackets 401. When the rotating shaft 407 rotates, the cam 408 and the connecting rod 409 can change the direction of the rotation of the rotating shaft 407 and transmit it to the retaining ring 402 connected to the connecting rod 409. The retaining ring 402 drives the plug block 403, the liquid guiding chamber 404 and other components to swing continuously. The worm gear 412 installed next to the wire 3 by the support 411 can transmit the rotation of the roller 413 to the rotating shaft 407 through the worm gear 410 when the roller 413 rotates continuously due to the friction of the moving wire 3. The liquid is connected to the outlet of the coolant circulation equipment with the filtration function through the liquid injection connector 414 so that the coolant circulating between the equipment and the cooling host 101 can be continuously introduced into the liquid guiding chamber 404 through the hose 415.
[0037] Working principle: When this device is installed for wire and cable drawing, the return end and outlet end of a coolant circulation device with filtration function are connected to the drain pipe 104 and the injection connector 414 respectively, so that the coolant can circulate between the device, the cooling host 101, and the cooling component 4.
[0038] As the surface-treated wire 3 passes through the wire drawing host 103, annealing host 102 and cooling host 101 cooling components 4 in sequence under the action of external wire feeding and winding equipment, its wire diameter will be gradually processed into the required specifications.
[0039] As the wire 3 passes through the cooling assembly 4, the roller 413, which is in continuous contact with the wire 3, drives the worm gear 412 to rotate due to the friction of the wire 3. The rotation of the worm gear 412 is transmitted through the worm wheel 410, the rotating shaft 407, the cam 408, and the connecting rod 409 to the retaining ring 402 connected to the connecting rod 409. Under the action of the above-mentioned power, the retaining ring 402 drives the plug 403 and the liquid guiding cavity 404 to swing continuously relative to the bracket 401. Therefore, each atomizing nozzle 405 facing the wire 3 in the liquid guiding cavity 404 will swing regularly around the wire 3 during the process of spraying the coolant injected into the liquid guiding cavity 404 onto the wire 3, so that the coolant can be sprayed more evenly onto the surface of the wire 3 to fully cool the wire 3. The coolant after contacting the wire 3 will fall from both sides of the retaining ring 402 to the bottom area of the cooling host 101 for recirculation.
[0040] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
