[0003] In order to restore the processing performance of the metal wire, the annealing machine as an important supporting equipment of the wire drawing machine is usually arranged after the drawing process or between multiple drawing passes.

[0049] The following reference Figures 1 to 15 This invention describes a wire drawing annealing machine provided in an embodiment of the invention.

[0050] like Figure 1 and Figure 2 As shown, the wire drawing annealing machine provided by the present invention is particularly suitable for annealing metal wire 150, and can also be used for annealing under other working conditions under appropriate circumstances.

[0051] The wire drawing annealing machine includes a main housing 100 and an annealing chamber 110. A mounting groove 101 is formed on the main housing 100, and the annealing chamber 110 is disposed within the mounting groove 101 and fixedly connected to the inner wall of the main housing 100. Multiple sets of first tension rollers 104, multiple sets of first roller shafts 106, multiple sets of second tension rollers 105, and multiple sets of second roller shafts 107 are arranged within the mounting groove 101. The first roller shafts 106 and second roller shafts 107 are spaced apart and are all vertically fixed to the inner wall of the main housing 100. The diameter of the second tension roller 105 is larger than the diameter of the first tension roller 104. The first tension roller 104 is coaxially rotatably connected to the first roller shaft 106, and the second tension roller 105 is coaxially rotatably connected to the second roller shaft 107. Additionally, a wire inlet 102 is provided on the side wall of the main housing 100 for feeding metal wire 150 into the mounting groove 101; a wire outlet 103 is provided on the other side wall of the main housing 100 for outputting metal wire 150 from the mounting groove 101. An annealing chamber 110 has an inlet hole 111 and an outlet hole 112. The inlet hole 111 is used to feed metal wire 150 into the annealing chamber 110, and the outlet hole 112 is used to output metal wire 150 from the annealing chamber 110.

[0052] The annealing chamber 110 has a first plate 121 and a second plate 122 arranged at intervals and both vertically fixed to the inner wall of the main housing 100. The annealing chamber 110, the first plate 121 and the second plate 122 together form a first chamber 131, a second chamber 132 and a third chamber 133. The second chamber 132 is equipped with an induction annealing furnace, which includes a heating plate 205 and a heating cylinder 206. The heating plate 205 and the heating cylinder 206 are fixedly connected. The heating plate 205 is fixedly connected to the inner wall of the main housing 100, and the heating cylinder 206 has a heating channel 207 extending along its own axial direction. The heating channel 207 is used for the metal wire 150 to pass through and be heated.

[0053] The second chamber 132 also contains a third plate 123 and a fourth plate 124, which are horizontally spaced apart. One end of the third plate 123 is fixedly connected to the first plate 121, and the other end is fixedly connected to the second plate 122; one end of the fourth plate 124 is fixedly connected to the first plate 121, and the other end is fixedly connected to the second plate 122. The second chamber 132 also contains a first guide shaft 241, a second guide shaft 242, a third guide shaft 243, and a fourth guide shaft 244. The first guide shaft 241, the second guide shaft 242, and the third guide shaft 243 are horizontally spaced between the first plate 121 and the second plate 122, and their two ends are fixedly connected to the first plate 121 and the second plate 122, respectively. The third guide shaft 243 is positioned above the second guide shaft 242, and the second guide shaft 242 is positioned above the first guide shaft 241.Figure 6 In the vertical direction, a fourth guide shaft 244 is provided between the third plate 123 and the fourth plate 124. One end of the fourth guide shaft 244 is fixedly connected to the third plate 123, and the other end is fixedly connected to the fourth plate 124. The fourth guide shaft 244 is spaced apart from the second guide shaft 242, and the fourth guide shaft 244 is located at the right end of the second guide shaft 242. Figure 6 The left and right directions in the middle.

[0054] A first guide wheel 251 is coaxially mounted on a first guide shaft 241, and the first guide wheel 251 can rotate around the axial direction of the first guide shaft 241; a second guide wheel 252 is coaxially mounted on a second guide shaft 242, and the second guide wheel 252 can rotate around the axial direction of the second guide shaft 242; a third guide wheel 253 is coaxially mounted on a third guide shaft 243, and the third guide wheel 253 can rotate around the axial direction of the third guide shaft 243; a fourth guide wheel 254 is coaxially mounted on a fourth guide shaft 244, and the fourth guide wheel 254 can rotate around the axial direction of the fourth guide shaft 244; furthermore, the first guide wheel 251, the second guide wheel 252, the third guide wheel 253, and the fourth guide wheel 254 are all used to guide the movement of the metal wire 150.

[0055] The wire drawing annealing machine also includes a heat exchange assembly disposed inside the annealing chamber 110. The heat exchange assembly and the heating cylinder 206 are disposed on the same vertical plane, and the heat exchange assembly is disposed at the upper end of the heating cylinder 206. Figure 6 The heat exchange component is positioned closer to the inlet hole 111 in the vertical direction.

[0056] Specifically, the unannealed metal wire 150 enters the mounting groove 101 from the wire inlet 102, is guided by the first tension roller 104 and the second tension roller 105 located at the top of the annealing box 110, and then enters the interior of the annealing box 110 from the wire inlet 111, and passes through the heat exchange assembly and the heating channel 207 in sequence.

[0057] In the heating channel 207, the unannealed metal wire 150 is heated to the temperature required for annealing. Subsequently, the annealed metal wire 150 is guided sequentially by the first guide wheel 251, the second guide wheel 252, and the fourth guide wheel 254 to ensure a stable running path.

[0058] Subsequently, the annealed metal wire 150 is wound a predetermined number of turns onto the heat exchange assembly and undergoes heat exchange. During this process, the annealed metal wire 150 transfers some of its heat to the unannealed metal wire 150, which enters through the wire inlet 111 and passes through the heat exchange assembly, thus preheating the unannealed metal wire 150 before it passes through the heating channel 207. Therefore, this not only effectively recovers and utilizes the waste heat of the annealed metal wire 150, reducing overall energy consumption, but also helps improve the stability of the annealing process.

[0059] After heat exchange is completed, the annealed metal wire 150 is guided by the third guide wheel 253 to pass through the wire outlet 112 and out of the annealing box 110. It is then guided by the remaining first tension roller 104 and second tension roller 105 in the mounting groove 101, passes through the wire outlet 103 and out of the mounting groove 101, and then enters the water-cooled box 140 that is matched with the wire drawing annealing machine.

[0060] In one embodiment, the heat exchange assembly includes a heat pipe 210, a guiding mechanism, and two sets of support arms 201. The heat pipe 210 is vertically arranged, and both sets of support arms 201 are fixedly connected to the main housing 100 and respectively fixedly connected to both ends of the heat pipe 210. The guiding mechanism includes multiple coaxially detachably connected spiral sleeve assemblies, which are coaxially arranged on the outside of the heat pipe 210. A first channel 211 extending axially is formed inside the heat pipe 210 for unannealed metal wire 150 to pass through. When the annealed metal wire 150 passes through the spiral sleeve assembly, the heat carried by the annealed metal wire 150 is transferred to the first channel 211, which can preheat the unannealed metal wire 150.

[0061] In one embodiment, each set of spiral sleeve assemblies includes a first semi-ring 301 and a second semi-ring 302. The first semi-ring 301 and the second semi-ring 302 are coaxially threadedly connected to the heat-conducting pipe 210, and both the first semi-ring 301 and the second semi-ring 302 are capable of relative rotation and relative sliding with respect to the heat-conducting pipe 210. A first protrusion 311 is fixedly provided on the top of both the first semi-ring 301 and the top of both the second semi-ring 302, and a first slot 321 is provided on the bottom of both the first semi-ring 301 and the bottom of both the second semi-ring 302. In the vertical direction, adjacent first semi-rings 301 are detachably connected by the cooperation of the first protrusion 311 and the first slot 321, and adjacent second semi-rings 302 are also detachably connected by the cooperation of the first protrusion 311 and the first slot 321.

[0062] Meanwhile, a second protrusion 312 is fixedly provided on one side wall of the first semi-ring sleeve 301, and a second slot 322 is provided on the other side wall. The second semi-ring sleeve 302 is symmetrically arranged with the first semi-ring sleeve 301 in terms of side wall structure. Therefore, in each set of spiral sleeve assemblies, the second protrusion 312 on the first semi-ring sleeve 301 engages with the second slot 322 on the second semi-ring sleeve 302, and the second protrusion 312 on the second semi-ring sleeve 302 engages with the second slot 322 on the first semi-ring sleeve 301, thereby realizing a laterally detachable connection between the first semi-ring sleeve 301 and the second semi-ring sleeve 302.

[0063] Furthermore, both the outer walls of the first semi-ring 301 and the second semi-ring 302 are provided with second channels 331. The second channels 331 extend spirally around the central axis of the heat pipe 210, and the second channels 331 on the outer walls of the first semi-ring 301 and the second channels 331 on the outer walls of the second semi-ring 302 are symmetrically arranged. When the first semi-ring 301 and the second semi-ring 302 are fitted together, the second channels 331 on the outer walls of the first semi-ring 301 and the second channels 331 on the outer walls of the second semi-ring 302 together form a complete, continuous spiral flow channel 332 around the axial direction of the heat pipe 210.

[0064] Specifically, magnets 333 are provided inside the first half-ring 301 and the second half-ring 302, and the magnetic force of the magnets 333 further enhances the stability of the connection.

[0065] Specifically, when the unannealed metal wire 150 enters the annealing chamber 110 through the inlet hole 111, it passes sequentially through the first channel 211 and the heating channel 207, where it is heated to the required annealing temperature. Subsequently, the annealed metal wire 150 is guided sequentially by the first guide wheel 251, the second guide wheel 252, and the fourth guide wheel 254, entering the spiral flow channel 332 from the second turn (from bottom to top) and winding a predetermined number of turns within the spiral flow channel 332. Simultaneously, it moves upwards along the axial direction of the heat pipe 210 within the spiral flow channel 332. Figure 6 In the vertical direction. During this process, the annealed metal wire 150 transfers part of its heat to the heat pipe 210 through the first half-ring 301 and the second half-ring 302. The heat pipe 210 then conducts the heat to the unannealed metal wire 150 in the first channel 211, thus achieving the preheating treatment of the unannealed metal wire 150.

[0066] Furthermore, since both the first semi-ring 301 and the second semi-ring 302 are threadedly connected to the heat pipe 210, when the annealed metal wire 150 moves within the spiral flow channel 332, friction causes all the first semi-rings 301 and all the second semi-rings 302 to rotate around the axial direction of the heat pipe 210 and move upwards along the axial direction of the heat pipe 210. Figure 6 In the vertical direction within the spiral sleeve assembly, to maintain the stability of the movement of the annealed metal wire 150 during this process, the guiding mechanism detaches the first half-ring 301 and the second half-ring 302 located at the top of the heat pipe 210 from the entire spiral sleeve assembly. Simultaneously, the first half-ring 301 and the second half-ring 302 gradually separate. Then, the separated first half-ring 301 and the second half-ring 302 are moved downwards along the axial direction of the heat pipe 210 to the bottom of the heat pipe 210. The first half-ring 301 and the second half-ring 302 are then reassembled and fitted together radially along the heat pipe 210, and reconnected to the entire spiral sleeve assembly along the axial direction of the heat pipe 210. This process is continuously repeated to ensure that the overall height remains constant, ensuring the continuity and stability of the annealed metal wire 150's movement within the spiral flow channel 332.

[0067] In one embodiment, the guiding mechanism includes a drive unit, a first gripping unit, and a second gripping unit. The drive unit includes a limiting rod 204, a reciprocating screw 202, and a sliding rod 203. Two sets of support arms 201 are respectively disposed at both ends of the limiting rod 204, allowing the limiting rod 204 to rotate relative to the two sets of support arms 201. A first gear 231 and a second gear 232 are coaxially fixedly disposed on the limiting rod 204, with the first gear 231 meshing with either the first semi-ring sleeve 301 or the second semi-ring sleeve 302. The two sets of support arms 201 are respectively disposed at both ends of the reciprocating screw 202, allowing the reciprocating screw 202 to rotate relative to the two sets of support arms 201. The support arm 201 rotates relative to the other arm; when the reciprocating screw 202 rotates around its own axis, the sliding rod 203 can slide along the axis of the reciprocating screw 202; a third gear 233 is fixedly installed on the reciprocating screw 202, and the third gear 233 meshes with the second gear 232; the first gripping unit drives the first half-ring 301 located at the top of the heat pipe 210 to move to the bottom of the heat pipe 210, and the second gripping unit drives the second half-ring 302 located at the top of the heat pipe 210 to move to the bottom of the heat pipe 210.

[0068] In one embodiment, the first gripping unit includes a first connecting rod 401, a first guide box 451, a first sensing claw, and a first sliding box 431. The first connecting rod 401 is slidably connected to one end of the sliding rod 203. The first sensing claw includes a first rod 411 and a first ring 421. The first rod 411 is fixedly connected to the first ring 421, and the first ring 421 can slide and rotate relative to the first half-ring sleeve 301 or the second half-ring sleeve 302. The first rod 411 is fixedly connected to the first sliding box 431, and the first guide box 451 is fixedly connected to the first plate 121. A first slider 441 is fixedly provided on the outer wall of the first sliding box 431, and a first slide rail 461 is provided on the inner wall of the first guide box 451, allowing the first slider 441 to slide within the first slide rail 461.

[0069] In one embodiment, the second gripping unit includes a second connecting rod 402, a second guide box 452, a second sensing claw, and a second sliding box 432. The second connecting rod 402 is slidably connected to the other end of the sliding rod 203. The second sensing claw includes a second rod 412 and a second ring 422. The second rod 412 is fixedly connected to the second ring 422, and the second ring 422 can slide and rotate relative to the first half-ring sleeve 301 or the second half-ring sleeve 302. The second rod 412 is fixedly connected to the second sliding box 432, and the second guide box 452 is fixedly connected to the second plate 122. A second slider 442 is fixedly provided on the outer wall of the second sliding box 432, and a second slide rail 462 is provided on the inner wall of the second guide box 452, allowing the second slider 442 to slide within the second slide rail 462.

[0070] Furthermore, the second slide rail 462 includes a first slide groove 471 and a second slide groove 472, wherein the tail end of the first slide groove 471 in the second slide rail 462 slopes downward to the left, i.e. Figure 11 The second slide 462 has a curved structure, with its curved opening facing the first slide 471. Both ends of the second slide 472 are connected to the first slide 471. In particular, the first slide 461 and the second slide 462 are symmetrical along the central axis of the heat pipe 210.

[0071] Specifically, electromagnetic blocks 483 are provided inside the first ring 421 and the second ring 422. The electromagnetic blocks 483 inside the first ring 421 and the second ring 422 will be energized and work when the first ring 421 is in contact with the first half-ring 301 at the top of the heat pipe 210 and the second ring 422 is in contact with the second half-ring 302 at the top of the heat pipe 210.

[0072] Specifically, the first half-ring 301 and the second half-ring 302 rotate around the axial direction of the heat pipe 210, which drives the limiting rod 204 to rotate around its own axial direction through the first gear 231, thereby driving the second gear 232 and the third gear 233 to rotate synchronously, thus driving the reciprocating screw 202 to rotate around its own axial direction.

[0073] Furthermore, a reciprocating slide rail is provided on the reciprocating screw 202, and the sliding rod 203 is slidably connected to the reciprocating slide rail. When the reciprocating screw 202 rotates around its own axis and the first ring 421 is in contact with the first half-ring 301 located at the top of the heat pipe 210, and the second ring 422 is in contact with the second half-ring 302 located at the top of the heat pipe 210, the sliding rod 203 simultaneously slides upward along the axis of the reciprocating screw 202 within the reciprocating slide rail, that is... Figure 8 The vertical movement causes the first link 401 and the second link 402 to move upwards synchronously, which in turn causes the first link 411, the second link 412, the first ring 421, the second ring 422, the first sliding box 431, and the second sliding box 432 to slide upwards synchronously.

[0074] During this process, the first slider 441 slides upward and to the left along the second groove 472 in the first slide rail 461, and the second slider 442 slides upward and to the right along the second groove 472 in the second slide rail 462. Figure 9 The first ring 421 moves to the upper left and the second ring 422 moves to the upper right, moving in the up-down and left-right directions. During this process, the first connecting rod 401 and the second connecting rod 402 remain slidably connected to the sliding rod 203. Simultaneously, the electromagnetic blocks 483 inside the first ring 421 and the second ring 422 are energized, generating magnetic attraction. This causes the first ring 421 to move the first half-ring 301 at the top of the heat pipe 210 to the upper left, and the second ring 422 to move the second half-ring 302 at the top of the heat pipe 210 to the upper right. This causes the first half-ring 301 and the second half-ring 302 to detach from the entire spiral sleeve assembly, and the first half-ring 301 and the second half-ring 302 gradually separate from each other.

[0075] Subsequently, after sliding to the top of the reciprocating screw 202, the sliding direction of the sliding rod 203 changes, that is, it slides downward along the axial direction of the reciprocating screw 202. Figure 8 The first slider 441 slides downward along the first groove 471 in the first slide rail 461, causing the first ring 421 to move the first half-ring sleeve 301 downwards simultaneously; at the same time, the second slider 442 slides downward along the first groove 471 in the second slide rail 462, causing the second ring 422 to move the second half-ring sleeve 302 downwards simultaneously. Figure 9In the vertical direction. When the first slider 441 slides to the end of the first groove 471 in the first slide rail 461, the first slider 441 slides along the first groove 471 to the lower right, causing the first ring 421 to drive the first half-ring sleeve 301 to move synchronously to the lower right; at the same time, when the second slider 442 slides to the end of the first groove 471 in the second slide rail 462, the second slider 442 slides along the first groove 471 to the lower left, causing the second ring 422 to drive the second half-ring sleeve 302 to move synchronously to the lower left, thereby causing the first half-ring sleeve 301 and the second half-ring sleeve 302 to gradually approach each other and re-fit into the bottom end of the heat pipe 210. At this time, the energization of the electromagnetic block 483 inside the first ring 421 and the electromagnetic block 483 inside the second ring 422 is canceled, causing their magnetism to be deactivated.

[0076] Subsequently, due to the magnetic force of the magnets 333 inside the first semi-ring 301 and the second semi-ring 302, the re-fitted first semi-ring 301 and second semi-ring 302 are attracted by the upper first semi-ring 301 and second semi-ring 302, and thus move upward along the axial direction of the heat pipe 210, that is... Figure 8 The upper and lower directions of the first half-ring 301 and the second half-ring 302 are aligned so that they fit together with the upper first half-ring 301 and the second half-ring 302, thereby allowing the re-fitted first half-ring 301 and the second half-ring 302 to reconnect to the entire spiral sleeve assembly.

[0077] Subsequently, after sliding to the bottom end of the reciprocating screw 202, the sliding direction of the sliding rod 203 changes, that is, it slides upward along the axial direction of the reciprocating screw 202, thereby driving the first rod 411, the second rod 412, the first sliding box 431, and the second sliding box 432 to slide upward synchronously. Figure 8 In the vertical direction, the first ring 421 and the second ring 422 are reset. During this process, when the first slider 441 slides to the connection between the first groove 471 and the second groove 472 in the first slide rail 461, the first slider 441 slides along the second groove 472 to the upper right, that is... Figure 9The second ring 422 gradually re-fits against the first half-ring 301 at the top of the heat pipe 210 in the up-down and left-right directions. Simultaneously, when the second slider 442 slides to the connection point of the first groove 471 and the second groove 472 in the second slide rail 462, the second slider 442 slides upward and to the left along the second groove 472, causing the second ring 422 to gradually fit against the second half-ring 302 at the top of the heat pipe 210, preparing for the next cycle. Therefore, this process continuously cycles, ensuring the continuous and stable movement of the annealed metal wire 150 in the spiral flow channel 332. Furthermore, the spiral winding of the annealed metal wire 150 in the spiral flow channel 332 effectively increases the contact area between the annealed metal wire 150 and the spiral flow channel 332, as well as the heat exchange time with the first half-ring 301 and the second half-ring 302, significantly improving the efficiency of heat recovery and utilization.

[0078] In particular, the annealed metal wire 150 exhibits excellent ductility and flexibility, enabling it to adapt to bending deformation during the spiral winding process without breaking or being damaged due to bending deformation, thus ensuring the physical properties of the metal wire 150. Simultaneously, the annealed metal wire 150 in its spiral state generates vibration and friction during movement, which helps to further loosen and detach the impurity layer formed on the surface of the metal wire 150 during the annealing process. This facilitates subsequent processes, thereby improving overall processing efficiency and product quality.

[0079] In one embodiment, the first gripping unit further includes a first one-way plate 481, which is disposed within the first slide rail 461 and rotatably connected to the first guide box 451. The first gripping unit also includes a first torsion spring, which is fixedly connected to the first guide box 451. The first one-way plate 481 achieves a one-way rotatable connection with the first guide box 451 via the torsion spring. The first one-way plate 481 can only rotate downwards. Figure 9 The vertical and horizontal directions within the first ring 421. During the reset process of the first ring 421, the first one-way plate 481 is used to ensure that the first slider 441 can slide along the right slope of the second groove 472 in the first slide rail 461 during the upward sliding process.

[0080] In one embodiment, the second gripping unit further includes a second one-way plate 482, which is disposed within the second slide rail 462 and rotatably connected to the second guide box 452. Further, the second gripping unit also includes a second torsion spring, which is fixedly connected to the second guide box 452. The second one-way plate 482 achieves a one-way rotatable connection with the second guide box 452 via the torsion spring. The second one-way plate 482 can only rotate downwards. Figure 9The vertical and horizontal directions within the ring 422. During the reset process of the second ring 422, the second one-way plate 482 is used to ensure that when the second slider 442 slides upward, the second slider 442 can slide along the left inclined surface of the second slide groove 472 in the second slide rail 462.

[0081] In one embodiment, a friction tube 220 is provided inside the annealing chamber 110. The friction tube 220 is positioned between the first guide wheel 251 and the second guide wheel 252, and is vertically fixed on the fourth plate 124. The friction tube 220 has a tapered structure, and its diameter gradually decreases from bottom to top along its own axial direction. Figure 6 The friction tube 220 has a friction channel extending along its own axial direction. Specifically, when the annealed metal wire 150 is introduced into the friction channel from the larger diameter end of the friction tube 220, the impurities formed on the surface of the metal wire 150 during the annealing process can be effectively cleaned by the contact friction between the inner wall of the friction channel and the surface of the metal wire 150.

[0082] The following are the working steps of a wire drawing annealing machine:

[0083] S100, the unannealed metal wire 150 enters the mounting groove 101 from the wire feed port 102, and is fed into the annealing box 110 through the wire inlet hole 111 by the guidance of the first tension roller 104 and the second tension roller 105 located at the top of the annealing box 110.

[0084] S110, the unannealed metal wire 150 passes through the first channel 211 inside the heat pipe 210 for preheating treatment;

[0085] S200, the unannealed metal wire 150 is heated to the annealing temperature by the heating channel 207 in the heating cylinder 206;

[0086] S210, the annealed metal wire 150 is guided to the friction tube 220 by the first guide wheel 251;

[0087] S220, the annealed metal wire 150 passes through the friction channel inside the friction tube 220 to clean the impurities formed on the surface of the metal wire 150 during the annealing process.

[0088] S230, the annealed metal wire 150 is guided by the second guide wheel 252 and the fourth guide wheel 254 in sequence, enters the spiral flow channel 332, and is wound several times in the spiral flow channel 332;

[0089] S300, the annealed metal wire 150 is wound in the spiral flow channel 332 and moves upward along the axis of the heat pipe 210. During this process, the annealed metal wire 150 transfers part of its heat to the heat pipe 210 through the first half ring 301 and the second half ring 302, and then the heat pipe 210 conducts it to the unannealed metal wire 150 in the first channel 211, thereby achieving the preheating treatment of the unannealed metal wire 150.

[0090] S310, the annealed metal wire 150 drives the first half-ring 301 and the second half-ring 302 to rotate and move upward through friction, and drives the reciprocating screw 202 to rotate through the first gear 231, the second gear 232 and the third gear 233.

[0091] S320, the first ring 421 and the second ring 422 respectively capture the first half-ring 301 and the second half-ring 302 located at the top of the heat pipe 210, and then separate them and move them to the bottom of the heat pipe 210 to re-fit them;

[0092] S400, after the annealed metal wire 150 is output from the spiral flow channel 332, it is guided by the third guide wheel 253 and enters the mounting groove 101 through the wire outlet hole 112 of the annealing box 110.

[0093] S500, the annealed metal wire 150 is guided sequentially through the remaining first tension roller 104 and second tension roller 105 in the mounting groove 101, and then passes out of the mounting groove 101 through the wire outlet 103;

[0094] S510, the annealed metal wire 150 finally enters the water-cooled box 140 that is matched with the wire drawing annealing machine.
