Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of metal wire deep processing, and particularly relates to a metal wire drawing device for metal mesh. BACKGROUND

[0002] The fundamental purpose of the metal wire drawing process is to process metal raw materials (wire rods or coarse wires) into fine wire products with specific sizes, shapes, surface states and mechanical properties through plastic deformation. The drawing process of metal wires is a cold (or warm) working process, which significantly changes the internal structure and properties of the metal. During the drawing process, the metal grains are elongated and broken, and the dislocation density increases sharply, resulting in a "work hardening" effect, thereby significantly improving the strength, hardness and hardness of the metal wire. Drawing causes the grains to be arranged in a certain direction, which leads to different properties of the material in the longitudinal (drawing direction) and transverse directions, which is a characteristic that needs to be utilized in some applications.

[0003] Before drawing, the metal wire coil needs to be unwound and then immersed in lubricating oil. After that, the metal wire is gradually drawn by the drawing equipment, and finally wound on the winding drum. During the unwinding of the metal wire, the metal wire is generally unwound passively, that is, through the winding action of the drawing equipment and the winding drum, the part of the metal wire in front of the drawing equipment has a certain sustained traction force, so that the metal wire coil is gradually unwound under the action of the traction force. However, during this process, the metal wire coil often unwinds too slowly or too quickly, so it is easy to cause the metal wire to scatter and knot. Moreover, when immersed in lubricating oil, the metal wire generally passes through the immersion bath in a single linear manner, so that the contact time between the lubricating oil and the metal wire is short, the lubricating oil on the surface of the metal wire cannot be fully attached, and the lubricating oil cannot fully and effectively remove the impurities on the surface of the metal wire, thereby affecting the subsequent drawing process. Moreover, the lubricating oil has a cooling effect, and after the metal wire is heated, the lubricating oil in the immersion bath cannot fully anneal the metal wire, thereby affecting the performance of the metal wire after drawing.

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present application will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0020] The present application discloses a metal wire drawing device for metal mesh, such as Figures 1-16As shown, including the self-unwinding mechanism 100, wire guide mechanism 300, multi-stage winding type immersion bath mechanism 500 and wire drawing winding mechanism 600 arranged in turn along the processing direction of the metal wire 700, the self-weight type tensioning mechanism 400 is installed on the wire guide mechanism 300, and the metal wire 700 passes through the self-weight type tensioning mechanism 400 during the process of passing through the wire guide mechanism 300. The working principle and advantages of the present application are that: the present application carries out unwinding operation on the metal wire 700 at a predetermined speed through the self-unwinding mechanism 100, thereby avoiding the situation of over-slow or over-speed unwinding, so as to effectively avoid the situation of over-tight or over-relaxed metal wire 700. After the metal wire 700 enters the wire guide mechanism 300, the wire guide mechanism 300 guides the metal wire 700, so that the metal wire 700 smoothly enters the multi-stage winding type immersion bath mechanism 500; during the process of the metal wire 700 passing through the wire guide mechanism 300, the metal wire 700 passes through the self-weight type tensioning mechanism 400, the self-weight type tensioning mechanism 400 tensioning the metal wire 700 through gravity and elastic force, so that the metal wire 700 enters the multi-stage winding type immersion bath mechanism 500 in a tensioned form. The part of the metal wire 700 in the multi-stage winding type immersion bath mechanism 500 is in a multi-stage winding form, and when the multi-stage winding type immersion bath mechanism 500 is controlled to act, the multi-stage winding type immersion bath mechanism 500 carries out the action of winding and unwinding the metal wire 700, thereby realizing the stable introduction and export of the metal wire 700 into and out of the multi-stage winding type immersion bath mechanism 500. Moreover, since the metal wire 700 in the multi-stage winding type immersion bath mechanism 500 is in a multi-stage winding form, the metal wire 700 is in full contact with the lubricating oil in the multi-stage winding type immersion bath mechanism 500. After the metal wire 700 passes through the multi-stage winding type immersion bath mechanism 500, it enters the wire drawing winding mechanism 600, the drawing force of the wire drawing winding mechanism 600 is controlled, the metal wire 700 with corresponding radial length is obtained, and the drawn metal wire 700 is wound up. As can be seen from the above, the present application can effectively ensure that the unwound metal wire 700 remains in a tensioned state, avoids the situation of scattered, knotted and the like of the metal wire 700, and improves the contact time of the metal wire 700 with the lubricating oil, so that the lubricating oil is fully attached to the surface of the metal wire 700, and the impurities attached to the metal wire 700 are fully separated, thereby improving the performance of the drawn metal wire 700.

[0021] As a preferred embodiment of the present application, Figures 3-5As shown, the self-unwinding mechanism 100 comprises a mounting base 103, a first power motor 104, a wire drum 101, a vertical rod 106 and a radial rod 108. The first power motor 104 is detachably mounted on the upper end of the mounting base 103, the wire drum 101 is placed on the mounting base 103, and the first power motor 104 extends into the wire drum 101 from the lower end of the wire drum 101. An active hole 102 extending along the axis of the wire drum 101 is formed on the wire drum 101, and the lower end of the vertical rod 106 is movably inserted into the wire drum 101 from the upper end of the wire drum 101 along the axis of the wire drum 101 through the active hole 102; an insertion interface 105 is formed on the upper end of the output shaft of the first power motor 104, and an insertion connector 107 is fixed on the lower end of the vertical rod 106, which is inserted into the insertion interface 105, and the axis of the output shaft of the first power motor 104, the vertical rod 106 and the wire drum 101 coincide. One end of the radial rod 108 is fixedly connected with the upper end of the vertical rod 106, which extends outward along the radial direction of the wire drum 101, and a wire guide ring 109 is arranged on the end of the radial rod 108 away from the vertical rod 106, through which the metal wire 700 unwound from the wire drum 101. The working principle and advantages of the present embodiment are as follows: the first power motor 104 is controlled to drive the vertical rod 106 to rotate along the axis of the wire drum 101, which in turn drives the radial rod 108 to rotate; the metal wire 700 wound on the wire drum 101 is gradually unwound during the rotation of the radial rod 108, which effectively avoids the situation that the metal wire 700 is unwound too slowly or too quickly, and prevents the metal wire 700 from being knotted when it is unwound in a spiral shape.

[0022] As a preferred embodiment of the present application, Figure 2 , 6As shown, the guide wire mechanism 300 comprises a vertical arm 301, a horizontal arm 302, a first guide wire wheel 303, a second guide wire wheel 304, an oblique arm 305 and an elastic telescopic arm. The lower end of the vertical arm 301 is installed on the ground, the horizontal arm 302 is configured at the upper end of the vertical arm 301, the wire transition assembly 200 is installed at the end of the horizontal arm 302 away from the vertical arm 301, the first guide wire wheel 303 and the second guide wire wheel 304 are installed on the horizontal arm 302 along the length direction of the horizontal arm 302, one end of the oblique arm 305 is hinged to the vertical arm 301, one end of the elastic telescopic arm is hinged to the oblique arm 305, the end of the elastic telescopic arm away from the vertical arm 301 is hinged to the oblique arm 305, and the self-weight type tensioning mechanism 400 is installed at the end of the oblique arm 305 away from the vertical arm 301. The elastic telescopic arm of the embodiment comprises an assembly tube 306 and an assembly rod 307, one end of the assembly rod 307 movably extends into the assembly tube 306, a first connecting spring is installed in the assembly tube 306, the two ends of the first connecting spring are connected with the inner wall of the assembly tube 306 and the end of the assembly rod 307 respectively, the end of the assembly tube 306 away from the assembly rod 307 is hinged to the vertical arm 301, and the end of the assembly rod 307 away from the first connecting spring is hinged to the oblique arm 305. The metal wire 700 passes through the wire transition assembly 200, the first guide wire wheel 303, the self-weight type tensioning mechanism 400 and the second guide wire wheel 304 in sequence after being unwound from the self-unwinding mechanism 100, the wire transition assembly 200 can effectively limit the metal wire 700 to avoid swinging of the metal wire 700, the self-weight type tensioning mechanism 400 can effectively tighten the metal wire 700, so that the metal wire 700 stably discharged from the second guide wire wheel 304 is in a tensioned state. When the metal wire 700 at the positions of the first guide wire wheel 303 and the second guide wire wheel 304 is in a relaxed state, the self-weight type tensioning mechanism 400 moves downward by a certain distance under the action of gravity, the oblique arm 305 swings downward, the elastic telescopic arm is correspondingly telescoped, and the metal wire 700 is gradually tensioned. When the metal wire 700 at the positions of the first guide wire wheel 303 and the second guide wire wheel 304 is in an over-tensioned state, the tensioning force of the metal wire 700 acts on the self-weight type tensioning mechanism 400, so that the self-weight type tensioning mechanism 400 moves upward, the oblique arm 305 swings upward, the elastic telescopic arm is correspondingly telescoped, and the metal wire 700 is gradually released from the over-tensioned state, so as to ensure that the metal wire 700 is stably conveyed under a predetermined tensioning force.

[0023] As a preferred embodiment of the present application, Figure 2 , 6As shown, the wire transition assembly 200 comprises a guide wire nozzle 201, a vertical guide tube 202 and an adapter ear 203. The guide wire nozzle 201 is a vertically arranged conical spring-shaped structure, the large diameter end of the guide wire nozzle 201 faces downward, and a connecting ring is coaxially fixed at the large diameter end and the small diameter end of the guide wire nozzle 201 respectively, so that the upper and lower ends of the guide wire nozzle 201 are in a smooth state. The small diameter end of the guide wire nozzle 201 is fixedly connected with the lower end of the vertical guide tube 202, and the upper end of the vertical guide tube 202 is detachably connected with the horizontal arm 302 through the adapter ear 203. The metal wire 700 is unwound from the self-unwinding mechanism 100 and enters the vertical guide tube 202 through the guide wire nozzle 201. Under the action of the guide wire nozzle 201 and the vertical guide tube 202, the metal wire 700 is prevented from swinging and vibrating when passing through the first guide wire wheel 303, and the metal wire 700 is prevented from being separated from the first guide wire wheel 303.

[0024] As a preferred embodiment of the present application, Figures 6-10 As shown, the self-weight type tensioning mechanism 400 comprises a mounting disc 401, an adapter shaft 411 and a plurality of elastic tension wire assemblies. The mounting disc 401 and the adapter shaft 411 are coaxially arranged, the adapter shaft 411 is rotationally connected at the end of the oblique arm 305 away from the vertical arm 301, and the plurality of elastic tension wire assemblies are uniformly arranged on the mounting disc 401 along the circumferential direction of the mounting disc 401. The metal wire 700 winds around the mounting disc 401 at least once, and each winding of the metal wire 700 is connected with each elastic tension wire assembly. During the process of passing through the self-weight type tensioning mechanism 400, the metal wire 700 presses on each elastic tension wire assembly. When the metal wire 700 is excessively tensioned, the force of the metal wire 700 pressing on each elastic tension wire assembly increases, so that the elastic tension wire assembly elastically deforms and stores energy. At the same time, the pulling force of the metal wire 700 is transmitted to the mounting disc 401, so that the mounting disc 401 is driven to rotate, i.e. the mounting disc 401 is passively rotated. At the same time, the oblique arm 305 and the elastic expansion arm change positions and elastically expand correspondingly, so as to effectively slow down the tensioning degree of the metal wire 700. Due to the rotation of the mounting disc 401, the metal wire 700 can smoothly pass through the self-weight type tensioning mechanism 400, and the metal wire 700 is prevented from being stuck in the self-weight type tensioning mechanism 400 due to excessive pulling force. In order to improve the smoothness of the metal wire 700 passing through the self-weight type tensioning mechanism 400, a second power motor 412 is installed on the oblique arm 305, the output shaft of the second power motor 412 is coaxially connected with the adapter shaft 411, and the second power motor 412 is controlled to drive the mounting disc 401 to rotate. The mounting disc 401 drives all the elastic tension wire assemblies to rotate along the axis of the mounting disc 401, so that the winding part of the metal wire 700 smoothly passes through, i.e. the mounting disc 401 is actively rotated.

[0025] As a preferred embodiment of the present application, as Figure 9 , 10As shown, the elastic tension wire assembly comprises a radial guide rail 402, a sliding block 403, a tensioning wheel 405, an externally threaded adjusting tube 407 and a connecting rod 409. Among them, the radial guide rail 402 extends outwardly along the radial direction of the mounting disc 401, the sliding block 403 is slidingly connected on the radial guide rail 402, and a connecting shaft 404 is connected on the sliding block 403, the axis of the connecting shaft 404 is parallel to the axis of the adapter shaft 411, the tensioning wheel 405 is coaxially assembled on the connecting shaft 404, and the tensioning wheel 405 is rotationally connected with the connecting shaft 404. In this embodiment, an assembly lug 406 is constructed at the end of the radial guide rail 402 away from the mounting disc 401, the externally threaded adjusting tube 407 is threadedly connected with the assembly lug 406, and the externally threaded adjusting tube 407 extends along the guidance of the radial guide rail 402, one end of the connecting rod 409 is movably inserted into the externally threaded adjusting tube 407, a second connecting spring is installed in the externally threaded adjusting tube 407, and the two ends of the second connecting spring are respectively connected with the inner wall of the externally threaded adjusting tube 407 and the end of the connecting rod 409; a connecting sleeve 410 is fixed at the other end of the connecting rod 409, the connecting sleeve 410 is sleeved on the connecting shaft 404, and the connecting sleeve 410 is fixedly connected with the connecting shaft 404, and an operating head 408 is constructed at the end of the externally threaded adjusting tube 407 away from the connecting shaft 404. Moreover, in order to avoid the situation that the weight of the self-weight type tensioning mechanism 400 is too heavy, the position cannot be changed when the pulling force of the metal wire 700 changes, or the metal wire 700 is broken, the following measures are taken: the mounting disc 401, the radial guide rail 402, the sliding block 403 and the tensioning wheel 405 are all made of lightweight polyethylene material or lightweight alloy material or carbon fiber material. The working principle and advantages of the present embodiment are as follows: during the process of the coiled metal wire 700 passing through each elastic tension wire assembly, the second connecting spring elastically drives the connecting rod 409 to move outwardly along the radial direction of the mounting disc 401, so that the tensioning wheel 405 elastically expands the metal wire 700, thereby ensuring that the metal wire 700 remains in a tensioned state when passing through the self-weight type tensioning mechanism 400; when the pulling force of the metal wire 700 changes, the second connecting spring will elastically deform accordingly, so that the tensioning wheel 405 always expands the metal wire 700. Moreover, during the process of the metal wire 700 passing through each elastic tension wire assembly, the tensioning wheel 405 rotates, thereby reducing the wear of the metal wire 700. In this embodiment, the externally threaded adjusting tube 407 can be rotated to move along the radial direction of the mounting disc 401, thereby driving the sliding block 403 and the tensioning wheel 405 to move along the radial direction of the mounting disc 401 through the connecting rod 409, thereby adjusting the radial length of the coiled metal wire 700 outside the self-weight type tensioning mechanism 400, and thereby adapting to the tensioning of metal wires 700 of different thicknesses. Moreover, the more the number of coils, the better the tensioning effect, but the more the number of coils, the greater the resistance, and when the number of coils exceeds a certain number, the metal wire 700 is prone to over-tensioning. Therefore, the optimal number of coils is 2-3.

[0026] As a preferred embodiment of the present application, as Figures 11-14As shown, the multi-stage winding type immersion mechanism 500 comprises an immersion tank 501, an import wheel 502, an export wheel 503 and a plurality of impeller type godets 504. The upper end of the immersion tank 501 is in an open state, and the immersion tank 501 is filled with lubricating oil; the import wheel 502 and the export wheel 503 are respectively installed at the upper end of the immersion tank 501, and the import wheel 502 and the export wheel 503 are arranged at the two ends along the conveying direction of the metal wire 700. The plurality of impeller type godets 504 are rotatably installed in the immersion tank 501 along the length direction of the immersion tank 501, and a driving assembly is installed outside the immersion tank 501, and the impeller type godets 504 are driven by the driving assembly to rotate. The metal wire 700 passes through each impeller type godet 504 in turn, and the metal wire 700 is wound on each impeller type godet 504. In this embodiment, all the impeller type godets 504 are driven by the driving assembly to rotate synchronously and in the same direction, and in the process of rotation, each impeller type godet 504 winds up one end of the metal wire 700 thereon and unwinds the other end of the metal wire 700, thereby realizing stable passage of the metal wire 700 through the immersion tank 501, increasing the length of the metal wire 700 in the immersion tank 501, improving the contact time of the metal wire 700 with the lubricating oil, and enabling the metal wire 700 to fully contact the lubricating oil without dead angle.

In the embodiment, the pressure pump is controlled to pump the lubricating oil in the intermediate tank into one of the impeller type godets 504 through the liquid inlet pipe 505, and then the lubricating oil is discharged into the immersion bath 501 through the liquid guide hole 5043 on the impeller type godet 504, in the process, the impurities on the metal wire 700 are quickly separated from the metal wire 700 by the impact of the lubricating oil. At the same time, the lubricating oil leaves the immersion bath 501 through the liquid guide hole 5043 on the other impeller type godet 504, in the process, the flowing lubricating oil impacts the metal wire 700 on the impeller type godet 504, which also achieves the effect of separating the impurities from the metal wire 700, and then the lubricating oil enters the intermediate tank through the liquid outlet pipe 506, thereby forming the circulation of the lubricating oil, so that the lubrication and impurity removal are continuously kept.

In this way, the driving motor 507 is controlled to drive the two impeller type godets 504 to synchronously and synchronously rotate through the transmission of the sprockets, thereby achieving the purpose of winding the metal wire 700 on one side and unwinding the metal wire 700 on the other side. In the embodiment, the impeller blades 5044 are made of elastic metal material, in the process of winding and unwinding the metal wire 700, the elastic impeller blades 5044 elastically expand to elastically expand the metal wire 700, so that the metal wire 700 is kept in tension when the tension changes. Moreover, in the process of rotating the impeller type godet 504, the lubricating oil is in a disturbed state under the action of the impeller blades 5044, which avoids the impurities from depositing at the bottom of the immersion bath 501, so that the impurities enter the filter with the lubricating oil and are filtered out, thereby reducing the frequency of cleaning the immersion bath 501.
