Description

Technical Field

[0001] The utility model relates to the field of galvanized wire heat treatment, in particular to a galvanized wire heat treatment device capable of reducing stress. Background Art

[0002] Galvanized wire is made from high-quality low-carbon steel through a series of processes, including drawing, pickling, rust removal, high-temperature annealing, hot-dip galvanizing, and cooling. Galvanized wire is further divided into hot-dip galvanized wire and electro-galvanized wire. Hot-dip galvanizing involves immersion in heated, molten zinc. This process is fast, resulting in a thick but uneven coating. The minimum thickness allowed by the market is 45 microns, and the maximum thickness can exceed 300 microns. The wire is darker in color, consumes more zinc, and forms an infiltration layer with the base metal, resulting in excellent corrosion resistance. Hot-dip galvanizing can maintain its performance for decades in outdoor environments. However, during the production process, significant internal stress is generated within the galvanized wire, threatening its service life. To overcome this internal stress, the industry often uses heat treatment.

[0003] After searching, the patent with publication number CN221460496U discloses an annealing carrier, including a support structure, an annealing fixture and an annealing furnace support structure. The annealing fixture is arranged in the middle, and the support structure and the annealing fixture are arranged inside the annealing furnace. The support structure includes a lower support pad arranged at the bottom of the inner wall of the annealing furnace and an upper support pad at the top of the inner wall. The upper support pad and the lower support pad are provided with buffer insulation rods on both sides of the outer wall away from the annealing furnace. A stamping spring is provided inside the buffer insulation rod, and a pressure rod is sleeved on the top of the stamping spring. The annealing fixture includes an upper convex clamp and a lower concave clamp. The upper convex clamp is arranged at the bottom of the upper support pad, and the lower concave clamp is arranged at the top of the lower support pad.

[0004] Existing equipment uses an annealing process to eliminate the internal stress inside the galvanized wire. After the sealed annealing furnace performs insulation annealing, another annealing of the galvanized wire requires the temperature inside the annealing furnace to be raised to the critical value again, resulting in a large amount of temperature loss.

[0005] Therefore, it is necessary to provide a galvanized wire heat treatment equipment that can reduce stress to solve the above technical problems. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 ,in, Figure 1A schematic structural diagram of a preferred embodiment of a galvanized wire heat treatment device capable of reducing stress provided by the present invention; Figure 2 for Figure 1 The structural schematic diagram of the gradually cooling structure shown; Figure 3 for Figure 1 The schematic diagram of the structure of the front cross-section shown; Figure 4 for Figure 1 The structural diagram of the transport structure shown is Figure 5 for Figure 3 The schematic structural diagram of the anti-deviating pinch roller shown in the figure includes a galvanized wire heat treatment device capable of reducing stress, comprising a heat treatment structure 1, a gradual cooling structure 2 provided on one side of the heat treatment structure 1, and a transport structure 3 provided outside the heat treatment structure 1 and the gradual cooling structure 2;

[0027] The heat treatment structure 1 includes a heat treatment box 101, and a plurality of annular electric heaters 102 are evenly spaced inside the heat treatment box 101;

[0028] The gradual cooling structure 2 includes an insulation box 201 welded to one side of the heat treatment box 101. Several air nozzles 202 are equidistantly connected to both sides of the top of the insulation box 201. The tops of the several air nozzles 202 are fixed to the same transport pipe 203. An air pump 204 is connected to one end of the transport pipe 203. The air pump 204 is fixedly arranged on the heat treatment box 101. One end of the air pump 204 extends through the heat treatment box 101 through a welded air inlet pipe 205.

[0029] It should be noted that: after the several annular electric heaters 102 are powered on, they generate heat and evenly heat the galvanized wire passing through, so that the temperature of the galvanized wire reaches the critical point. The insulation box 201 prevents the incoming heat from leaking out quickly, providing conditions for the subsequent annealing of the galvanized wire. The air pump 204 generates suction to absorb the hot air inside the heat treatment box 101 and transport it to the inside of the insulation box 201. Because the transport pipe 203 is too long, the farther the air nozzle 202 is from the air pump 204, the less hot air it can obtain.

[0030] In the specific implementation process, refer to Figure 1 and Figure 3 As shown, the heat treatment structure 1 further includes a galvanized wire inlet 103 opened at the bottom of one side of the heat treatment box 101 , and a galvanized wire outlet 104 opened at the bottom of the other side of the heat treatment box 101 .

[0031] It should be noted that the galvanized wire is added to the interior of the heat treatment box 101 through the galvanized wire inlet 103, and several annular electric heaters 102 perform electric heating. After the galvanized wire is heated to the critical point, it is transported to the galvanized wire outlet 104 for discharge and annealing treatment.

[0032] In the specific implementation process, refer to Figure 3 and Figure 4 As shown, the transport structure 3 includes a frame 301 fixedly arranged outside the heat treatment box 101 and the insulation box 201, and a plurality of rotating shafts 302 are equidistantly arranged inside the frame 301. Both ends of the plurality of rotating shafts 302 are installed with a plurality of anti-deviation clamping rollers 303 through the provided threads.

[0033] It should be noted that: the frame 301 stably supports the heat treatment box 101 and the insulation box 201 to increase the placement stability. The two ends of the several rotating shafts 302 are respectively provided with right-handed threads and left-handed threads. The two ends of the several rotating shafts 302 are symmetrically provided with anti-deviation clamping rollers 303 through right-handed threads or left-handed threads. The several anti-deviation clamping rollers 303 are all composed of a threaded sleeve and a rotating roller that are rotatably sleeved. The several anti-deviation clamping rollers 303 are all frustum-shaped.

[0034] In the specific implementation process, refer to Figure 1 and Figure 3 As shown, an adjustable feeding structure 4 is provided on one side of the frame 301, and the adjustable feeding structure 4 includes a slide groove 401 opened at the bottom of one end of the frame 301, and a double-headed screw rod 402 is rotatably provided inside the slide groove 401, and sliders 403 are slidably provided at both ends of the double-headed screw rod 402. One end of the double-headed screw rod 402 extends through the slide groove 401 and is fixedly provided with an adjustment handle 405. An alignment opening 406 is opened at the top of one end of the frame 301, and feeding rollers 404 are rotatably provided on the tops of the two sliders 403. The bottom end of the left feeding roller 404 of the two feeding rollers 404 is plugged with a motor 407, and the top of the motor 407 is fixedly provided on the corresponding slider 403.

[0035] It should be noted that: the two ends of the double-headed screw rod 402 are respectively provided with a right-hand thread and a left-hand thread. The manual rotation adjustment handle 405 controls the rotation of the double-headed screw rod 402, and controls the sliders 403 at both ends to slide closer to or away from each other along the slide groove 401, so as to realize the two feeding rollers 404 to synchronously clamp or release the galvanized wire. Then the motor 407 controls the corresponding feeding roller 404 to rotate, and drives the clamped galvanized wire to pass through the alignment port 406 for feeding.

[0036] In the specific implementation process, refer to Figure 1 and Figure 2 As shown, support legs 5 are provided at the four corners of the bottom end of the frame 301 .

[0037] It should be noted that the four balanced support legs 5 support the frame 301 to prevent the problem of materials falling.

[0038] The working principle of the galvanized wire heat treatment equipment that can reduce stress provided by the utility model is as follows:

[0039] When in use, the rotating adjustment handle 405 controls the double-headed screw rod 402 to rotate. The double-headed screw rod 402 relies on the left-handed thread and the right-handed thread respectively opened at both ends to engage and drive the two sliders 403 to slide along the slide groove 401 until the two feeding rollers 404 clamp the galvanized wire. The motor 407 controls the corresponding feeding roller 404 to rotate, and controls a section of galvanized wire to pass through the galvanized wire inlet 103 to move into the heat treatment box 101, and is clamped by the two anti-deviating clamping rollers 303 to avoid left and right. It deviates to the right and then passes through several annular electric heaters 102 for heating until the galvanized wire is heated to the critical point and maintained for a certain time. The galvanized wire is then discharged to the insulation box 201 through the galvanized wire discharge port 104. At this time, another galvanized wire enters the heat treatment box 101 to repeat the heating behavior. The air pump 204 transports the heat inside the heat treatment box 101 through the transport pipe 203 to several air nozzles 202 for ejection, keeping the temperature inside the insulation box 201 gradually decreasing, so as to complete the annealing behavior.
