Description

Technical Field

[0001] The present invention belongs to the technical field of metal wire processing in the production of metal meshes. Specifically, it relates to an annealing device for metal wires used in metal meshes. Background Art

[0002] Currently, in the production and processing operations of metal meshes, it is necessary to anneal the metal wires used to enhance the performance of the metal wires, thereby ensuring that the quality of the produced metal meshes meets the requirements. The annealing principle of metal wires is to heat the metal wires to a specific temperature and maintain for a period of time, and then slowly cool them, thereby eliminating the internal stress of the metal wires, improving the ductility or toughness of the metal wires, refining the internal grain structure, and improving their mechanical properties or processing properties. However, during the process of synchronous annealing of multiple metal wires, when the metal wires are unrolled from the pay-off reel, there will be situations such as jumping and shaking. Without taking measures, it is extremely easy to occur situations such as the metal wires being intertwined and knotted, which affects the annealing efficiency. Moreover, after annealing, these metal wires need to be synchronously wound up so that each metal wire is wound on the corresponding take-up reel. However, during the winding process, without external intervention, it is extremely easy to cause the situation that the metal wires are wound too loosely. And generally, after annealing, due to the increased ductility of the metal wires, wire drawing operations can be carried out on the metal wires, that is, gradually draw the thicker metal wires thinner; in this way, corresponding wire drawing equipment needs to be equipped, and the wire drawing ranges of existing wire drawing equipment are mostly not adjustable. Thus, it can be seen that in order to achieve the purpose of wire drawing, the cost of equipment investment is increased, and different models of wire drawing equipment are equipped according to different requirements for thickness.

Detailed implementation mode

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0019] The present invention discloses a metal wire annealing device for metal mesh, as Figures 1 to 19As shown, the wire laying and guiding mechanism 100, the electric heating cabinet 500, the multi-stage cooling trough 600, and the self-tensioning winding mechanism 800 are sequentially arranged along the conveying direction of the metal wire. Among them, one or more adjustable wire-managing mechanisms 300 are arranged between the wire laying and guiding mechanism 100 and the electric heating cabinet 500, and one or more adjustable wire-managing mechanisms 300 are also arranged between the multi-stage cooling trough 600 and the self-tensioning winding mechanism 800. The present invention uses multiple parallel wire guide tubes 400 arranged in the electric heating cabinet 500 and the multi-stage cooling trough 600. Each wire guide tube 400 passes through the electric heating cabinet 500 and the multi-stage cooling trough 600 along the conveying direction of the metal wire, and each metal wire passes through the corresponding wire guide tube 400. Multiple unwinding drums 200 are arranged in an array below the wire laying and guiding mechanism 100. The operating principle and advantages of the present invention are as follows: Multiple unwinding drums 200 unwind multiple wires, which are then guided and preliminarily arranged by a wire routing and guiding mechanism 100. Furthermore, before the wires enter the self-tensioning reeling mechanism 800, they are combed by multiple adjustable wire-straightening mechanisms 300, preventing loosening and tangling during wire transportation and processing. The present invention heats the portion of the wire guide tube 400 into which it extends, heating the wire as it passes through this heated portion of the tube. Furthermore, multi-stage cooling troughs 600 cool the portion of the wire guide tube 400 into which it extends, cooling the wire stepwise as it passes through this cooled portion of the tube. This prevents the wire from cooling too quickly, which could affect the annealing effect, or too slowly, which could affect efficiency. The present invention uses a self-tensioning winding mechanism 800 to wind the annealed metal wire. During the winding process, the self-tensioning winding mechanism 800 elastically tensions the metal wire so that the metal wire is always in a tensioned state, thereby preventing the wound metal wire from becoming loose. Moreover, the present invention can adjust the self-tensioning winding mechanism 800 so that the metal wire being wound is tensioned according to a predetermined tension, thereby achieving the purpose of wire drawing; and the fineness of the wire drawing can be adjusted by adjusting the tension of the metal wire. In summary, the present invention can effectively avoid situations such as the metal wire being scattered, intertwined, and knotted, thereby preventing the efficiency of annealing from being affected, and ensuring that the annealed metal wire is wound in a tensioned state; at the same time, the metal wire can be stably drawn by steplessly adjusting the radial length of the metal wire according to the requirements.

[0020] As a preferred embodiment of the present invention, Figure 2 、 Figure 3 、 Figure 4As shown, the wire guiding mechanism 100 includes a mounting frame 101, a second cross bar 105, and multiple first cross bars 102. Among them, these first cross bars 102 are arranged at intervals along the conveying direction of the wire on the upper end of the mounting frame 101. A plurality of first connecting sleeves 103 are fixedly connected to each first cross bar 102, and each first connecting sleeve 103 is detachably connected to the upper end of the mounting frame 101; a plurality of first wire guiding wheels 104 are rotatably mounted on each first cross bar 102, and these first wire guiding wheels 104 are arranged at intervals along the length direction of the first cross bar 102. The second cross bar 105 is arranged on the mounting frame 101 and near one end of the electric heating cabinet 500. A plurality of second connecting sleeves 106 are fixedly connected to the second cross bar 105, and each second connecting sleeve 106 is detachably connected to the upper end of the mounting frame 101; a plurality of second wire guiding wheels 107 are rotatably mounted on the second cross bar 105, and these second wire guiding wheels 107 are arranged at intervals along the length direction of the second cross bar 105. The wire is unrolled from the pay-off reel 200 and passes through the corresponding plurality of first wire guiding wheels 104 in sequence, and then passes through the corresponding second wire guiding wheels 107. The function of the first wire guiding wheel 104 is to guide the wire and perform preliminary sorting. The second wire guiding wheel 107 is used to smoothly transition the wire to the adjacent adjustable wire sorting mechanism 300 to ensure the stable conveyance of the wire. The specific structure of the first wire guiding wheel 104 in this embodiment is that the first wire guiding wheel 104 includes a guiding wheel body 1041 and an elastic rubber sleeve 1043. A metal sleeve is coaxially fixed to the inner peripheral wall of the elastic rubber sleeve 1043, and the metal sleeve is rotatably sleeved outside the first cross bar 102, and the guiding wheel body 1041 is fixedly sleeved outside the elastic rubber sleeve 1043. A first wire guiding groove 1042 is formed on the outer peripheral surface of the guiding wheel body 1041, and the axis of the first wire guiding groove 1042 coincides with the axis of the guiding wheel body 1041. During the process of the wire being conveyed through the first wire guiding groove 1042, when the wire is subjected to a deflecting force or the force changes, the guiding wheel body 1041 transfers the external force transmitted by the wire to the elastic rubber sleeve 1043, and the elastic rubber sleeve 1043 absorbs this part of the external force and undergoes a certain elastic deformation, causing the guiding wheel body 1041 to tilt to a certain extent, thereby offsetting the additional force borne by the wire and preventing the wire from being overstressed and resulting in a decrease in its performance; moreover, the guiding wheel body 1041 can adapt to the wire coming from multiple angles without the need to accurately align the wire with the guiding wheel body 1041, reducing the difficulty of calibration operations. In this embodiment, a second wire guiding groove 108 is formed on the outer peripheral surface of the second wire guiding wheel 107, the axis of the second wire guiding groove 108 coincides with the axis of the second wire guiding wheel 107, and the diameter of the second wire guiding groove 108 gradually expands radially outward along the second wire guiding wheel 107.When the wire enters the adjustable wire arranging mechanism 300 through the second wire guiding groove 108, since the caliber of the second wire guiding groove 108 gradually expands outwards, the wire can enter multiple positions of the adjustable wire arranging mechanism 300 within a certain angle range; that is, the number of wires passing through the same second wire guiding groove 108 is multiple. When these wires leave the second wire guiding groove 108, they can smoothly enter the adjustable wire arranging mechanism 300 in a dispersed form.

[0021] As a preferred embodiment of the present invention, as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown in the figure, the unwinding reel 200 includes a driving base 205 and a wire winding cylinder 201. The wire winding cylinder 201 is detachably assembled on the driving base 205. The metal wire to be annealed is wound on the wire winding cylinder 201, and the wire winding cylinder 201 is arranged vertically. In this embodiment, a fixing ring 203 is detachably connected to the upper end of the wire winding cylinder 201, and a plurality of metal damping wires 204 are installed between the fixing ring 203 and the wire winding cylinder 201. These metal damping wires 204 are evenly arranged along the circumferential direction of the wire winding cylinder 201, and each metal damping wire 204 extends radially outward along the wire winding cylinder 201; a lifting ring 202 is fixed at the center of the upper end of the wire winding cylinder 201 to facilitate the lifting and transfer of the wire winding cylinder 201. The working principle and advantages of this embodiment are as follows: In this embodiment, by controlling the movement of the driving base 205, the driving base 205 drives the wire winding cylinder 201 to rotate and unwind the metal wire to be annealed. The metal wire turns along the vertical direction through the adjacent first wire guiding wheels 104 and moves along the length direction of the mounting frame 101. When the metal wire leaves the wire winding cylinder 201, it will contact the metal damping wire 204. The metal damping wire 204 can effectively offset the large-amplitude fluctuation of the metal wire, that is, the metal damping wire 204 plays a role in restricting and dissipating energy for the metal wire, improving the stability of the upward movement of the metal wire and avoiding the situation that the metal wire disengages from the corresponding first wire guiding wheel 104. The driving base 205 of this embodiment includes a fixing base 2051, a vertical shaft 2052, a pneumatic impeller 2055, a fitting sleeve 2056 and two mounting discs 2054. Among them, the fixing base 2051 is fixedly installed on the ground, the lower end of the vertical shaft 2052 is rotatably installed on the fixing base 2051, the two mounting discs 2054 are fixedly installed on the vertical shaft 2052 at intervals in the vertical direction, the pneumatic impeller 2055 is fixed between the two mounting discs 2054, the fitting sleeve 2056 is rotatably sleeved outside the two mounting discs 2054, and the fitting sleeve 2056 is connected and fixed to the fixing base 2051 through a fixing ear 2059. An air inlet pipe 2057 and an exhaust pipe 2058 are communicated on the fitting sleeve 2056. The axes of the fixing base 2051, the vertical shaft 2052, the pneumatic impeller 2055, the fitting sleeve 2056 and the two mounting discs 2054 coincide. In this embodiment, a plug connector 2053 is constructed at the upper end of the vertical shaft 2052, and a plugging groove 206 is coaxially constructed at the lower end of the wire winding cylinder 201; when the wire winding cylinder 201 is assembled on the driving base 205, the plug connector 2053 is inserted into the plugging groove 206. An air inlet main pipe 900 is arranged below the wire guiding mechanism 100. A plurality of air inlet branch pipes 901 are communicated side by side on the air inlet main pipe 900, and each air inlet branch pipe 901 is connected to a plurality of corresponding air inlet pipes 2057.The working principle and advantages of this embodiment are as follows: The pressurized gas enters each intake branch pipe 901 through the main intake pipe 900. Then, it directly drives the pneumatic impeller 2055 to rotate through each intake pipe 2057. In this way, the pneumatic impeller 2055 drives the vertical shaft 2052, two mounting plates 2054, and the wire winding cylinder 201 to rotate, enabling the wire winding cylinder 201 to unwind the metal wire thereon. When the unwinding of the metal wire on the wire winding cylinder 201 is completed, the wire winding cylinder 201 can be removed and a new wire winding cylinder 201 can be replaced. In this embodiment, since the wire winding cylinder 201 is connected to the drive seat 205 in an inserted manner, it is convenient for replacement operations. Moreover, all drive seats 205 can be actuated by the pressurized gas, enabling all wire winding cylinders 201 to unwind synchronously, avoiding deviations caused by different unwinding speeds.

[0022] As a preferred embodiment of the present invention, as Figure 10 , Figure 11 , Figure 12As shown in the figure, the adjustable wire arranging mechanism 300 includes a transverse vertical plate 301, a wire arranging assembly, and two first vertical lead screws 312. Among them, the wire arranging assembly is installed at one end face of the transverse vertical plate 301. A plurality of strip-shaped wire arranging holes 302 are formed at intervals along the extending direction of the transverse vertical plate 301, and each strip-shaped wire arranging hole 302 extends vertically. A plurality of connecting ears 304 are formed at the lower end of the transverse vertical plate 301, and these connecting ears 304 are connected to the mounting frame 101 or the support frame. The two first vertical lead screws 312 are respectively rotatably connected to the upper ends on both sides of the wire arranging assembly. Each first vertical lead screw 312 is threadedly connected with a transfer plate 311, and the transfer plate 311 is detachably connected to the transverse vertical plate 301. The specific structure of the wire arranging assembly in this embodiment is that the wire arranging assembly includes two vertical seats 305 and multiple pairs of wire arranging rods 308. The two vertical seats 305 are symmetrically arranged on both sides of the transverse vertical plate 301. Vertical sliding grooves 303 are respectively formed on both sides of the transverse vertical plate 301. Vertical sliding strips 306 are formed on each vertical seat 305, and the vertical sliding strips 306 are slidably assembled in the corresponding vertical sliding grooves 303, so as to achieve the purpose of vertically sliding connection between the vertical seat 305 and the transverse vertical plate 301. In this embodiment, a plurality of strip-shaped mounting holes 307 are formed at intervals in the vertical direction on the vertical seat 305, and each strip-shaped mounting hole 307 extends in the vertical direction. The two wire arranging rods 308 in each pair of wire arranging rods 308 are arranged at intervals in the vertical direction, and connection heads 309 are respectively formed at both ends of each wire arranging rod 308. In this embodiment, multiple pairs of wire arranging rods 308 are installed at each strip-shaped mounting hole 307. The connection heads 309 at the ends of each wire arranging rod 308 pass through the corresponding strip-shaped mounting holes 307, and fastening nuts 310 are threadedly connected to the connection heads 309. By tightening the fastening nuts 310, the purpose of detachably connecting the end of the wire arranging rod 308 to the corresponding vertical seat 305 is achieved. In this embodiment, the distance between the two wire arranging rods 308 in each pair of wire arranging rods 308 can be adjusted, so that when the metal wire passes through the transverse vertical plate 301, the vertical displacement of the metal wire is restricted, and under the restriction of the strip-shaped wire arranging holes 302, multiple metal wires pass through the transverse vertical plate 301 smoothly in a predetermined arrangement manner. In this embodiment, a first operation handwheel 313 is installed at the upper end of each first vertical lead screw 312. By synchronously rotating the two first operation handwheels 313, the two first vertical lead screws 312 drive the two vertical seats 305 to move vertically, and then drive the multiple pairs of wire arranging rods 308 thereon to move in the vertical direction, so as to synchronously adjust the angle, height, etc. of the metal wire passing through the transverse vertical plate 301, and ensure that the metal wire passes through the transverse vertical plate 301 smoothly.

Inside the cooling tank body 601, a plurality of partition plates 602 are constructed at intervals along the conveying direction of the wire. These partition plates 602 divide the inner cavity of the cooling tank body 601 into a plurality of independent cooling chambers 603. At the positions of the outer side walls of the cooling tank body 601 corresponding to each cooling chamber 603, a water inlet joint 604 and a drain joint 605 are respectively constructed. The drain joint 605 is located above the water inlet joint 604. Cooling water at different temperatures enters each cooling chamber 603 respectively, that is, the temperature of the cooling water decreases along the conveying direction of the wire, thereby gradually and smoothly cooling the wire and avoiding the influence on the performance and annealing efficiency of the wire due to too fast or too slow cooling.

[0024] As a preferred embodiment of the present invention, in order to ensure that the wire can smoothly transition to the self-tensioning winding mechanism 800, the measures taken are as Figure 1 、 Figure 14 shown, a transition mechanism 700 is provided at the inlet end of the self-tensioning winding mechanism 800. The transition mechanism 700 includes at least two transition rollers 702 arranged in parallel. The arrangement of these transition rollers 702 is based on the smooth transition of the wire from the adjustable wire arranging mechanism 300 to the self-tensioning winding mechanism 800. Two lateral arms 701 are rotatably installed on both sides of these transition rollers 702. After the wire passes through each transition roller 702 in sequence, it smoothly enters the self-tensioning winding mechanism 800.

[0025] As a preferred embodiment of the present invention, as Figure 15 、 Figure 16 、 Figure 17 、 Figure 18 、 Figure 19As shown, the self-tensioning winding mechanism 800 includes a plurality of self-tensioning units 802 and a plurality of adjustable wire drawing units 805. The plurality of self-tensioning units 802 are installed between two first longitudinal beams 801 arranged side by side. These self-tensioning units 802 are spaced apart along the length of the first longitudinal beams 801, and the height of these self-tensioning units 802 decreases in the direction away from the multi-stage cooling trough 600. Two second longitudinal beams 803 are arranged side by side below the self-tensioning units 802. The adjustable wire drawing units 805 are installed between the two second longitudinal beams 803. These adjustable wire drawing units 805 are spaced apart along the length of the second longitudinal beams 803. A winding unit 806 is provided below each adjustable wire drawing unit 805, and the adjustable wire drawing units 805 are arranged one-to-one with the self-tensioning units 802. In this embodiment, since the height of the self-tensioning unit 802 is set in a gradient, multiple metal wires are divided into multiple batches and supplied to the corresponding adjustable wire drawing unit 805 respectively, avoiding interference between the metal wires. In addition, the self-tensioning unit 802 can effectively tension the multiple metal wires passing through, avoiding the occurrence of shaking, jumping, etc. due to changes in the force of the metal wires being pulled. The specific structure of the self-tensioning unit 802 in this embodiment is that the self-tensioning unit 802 includes a wire guide rod 8022, a first self-tensioning rod 8023 and a second self-tensioning rod 8024, the axes of the three are parallel, and the wire guide rod 8022, the first self-tensioning rod 8023 and the second self-tensioning rod 8024 are arranged in sequence in a vertical direction downward, and the metal wires pass through the wire guide rod 8022, the first self-tensioning rod 8023 and the second self-tensioning rod 8024 in sequence. Among them, the two ends of the guide rod 8022 are respectively connected to the adapter seat 8021, and the second vertical screw 8027 is rotatably connected to each adapter seat 8021. The second vertical screw 8027 is threadedly connected to the corresponding first longitudinal beam 801, and a second operating handwheel 8028 is installed at the upper end of the second vertical screw 8027. The guide rod 8022 and the same side end of the first self-tensioning rod 8023 are connected through the first connecting arm 8025, and the first self-tensioning rod 8023 and the second self-tensioning rod 8024 are connected through the second connecting arm 8026. A torsion spring is provided at the connection between the first connecting arm 8025 and the adapter seat 8021, and a torsion spring is also provided at the connection between the first connecting arm 8025 and the second connecting arm 8026. In this embodiment, by synchronously rotating the two second operating hand wheels 8028, the two second vertical screws 8027 drive the guide wire rod 8022, the first self-tensioning rod 8023 and the second self-tensioning rod 8024 to rise or fall synchronously, thereby adjusting the self-tensioning unit 802 to a suitable guide wire and self-tensioning height.In this embodiment, vertical plates 804 are respectively arranged on each second longitudinal beam 803 and at the ends of respective adjustable wire drawing units 805. Among them, the vertical plate 804 includes a vertical plate body 8041, on which a strip-shaped movable hole 8042 extending in the vertical direction is formed. At the lower end of the vertical plate body 8041, an assembly opening 8043 is formed. At the lower end of the assembly opening 8043, an assembly block 8044 is arranged. On both sides of the assembly block 8044, assembly ears 8045 are respectively constructed. The assembly ears 8045 are detachably connected to both sides of the assembly opening 8043, and the assembly block 8044 extends into the assembly opening 8043. The winding unit 806 of this embodiment includes a winding rod 8061, on which a plurality of winding drums 8062 are installed at intervals along its length direction. Both ends of the winding rod 8061 are respectively assembled in the corresponding assembly openings 8043 and are rotatably connected to the vertical plate body 8041 through the assembly blocks 8044. A transmission wheel is coaxially installed at one end of the winding rod 8061. By driving the transmission wheel to rotate, it drives each winding drum 8062 to rotate through the winding rod 8061, thereby performing the winding operation on the metal wire. The adjustable wire drawing unit 805 of this embodiment includes two wire drawing rollers 8051, which are arranged at intervals in the vertical direction. On the outer peripheral surface of each wire drawing roller 8051, a plurality of wire drawing guide grooves 8052 are formed at intervals along its length direction. The wire drawing guide grooves 8052 coincide with the axis of the wire drawing roller 8051. At both ends of the wire drawing roller 8051, adapter joints 8053 are respectively coaxially constructed. The wire drawing roller 8051 located above is rotatably connected to the two vertical plates 804 through the two adapter joints 8053 thereon. The adapter joints 8053 at each end of the wire drawing roller 8051 located below extend out of the corresponding strip-shaped movable hole 8042 movably; at the lower end of each second longitudinal beam 803, a vertical driving member 8054 is installed. The vertical driving member 8054 is generally a hydraulic cylinder. The driving end of the vertical driving member 8054 is rotatably connected to the corresponding end of the wire drawing roller 8051 located below. The metal wire is wound between the two wire drawing rollers 8051 (not wound around a single wire drawing roller 8051 alone, but regarding the two wire drawing rollers 8051 as a whole structure and winding around this whole structure). Generally, after winding 2 - 5 turns, it is wound on the corresponding winding drum 8062. And due to the arrangement of the winding on the wire drawing rollers 8051, the situation that the part of the metal wire from the self-tensioning unit 802 to the winding drum 8062 is slack is avoided. In this embodiment, by controlling the operation of the vertical driving member 8054, the distance between the two wire drawing rollers 8051 can be adjusted. In this way, the metal wire wound between the two wire drawing rollers 8051 is tensioned according to a predetermined tensile force, so that the metal wire is gradually drawn thinner. And in this embodiment, by driving the vertical driving member 8054 to act, the tensile force of the metal wire wound between the two wire drawing rollers 8051 can be adjusted, and thus metal wires of corresponding fineness can be obtained.Since the tensile force is adjusted steplessly by the vertical driving member 8054, metal wires of any fineness can be obtained, and there will be no situation where certain fineness cannot be obtained through tensioning.
