Description

Technical Field

[0001] This invention relates to the field of heat treatment technology, specifically to a heat treatment device for austenitic corrosion-resistant stainless steel wire. Background Technology

[0002] While existing heat treatment equipment for super austenitic corrosion-resistant stainless steel wire can perform continuous solution treatment and rapid cooling to achieve excellent corrosion resistance and good mechanical properties, it has significant shortcomings in the end-of-line treatment of the wire during winding.

[0003] Patent publication number CN217757575U includes a workbench, a heating assembly, and an annealing tube. Both the heating assembly and the annealing tube are mounted on the workbench. The heating assembly includes an insulating frame mounted on the workbench, on which a first heating wire and a second heating wire for preheating a stainless steel wire are installed. The annealing tube includes a quenching tube and an annealing tube, both mounted on the insulating frame. A quenching agent tank and a steam tank are mounted on the workbench. The quenching agent tank is equipped with an atomizing nozzle via a first delivery pipe, and the steam tank is connected to the annealing tube via a second steam delivery pipe. This patent uses contact current to preheat the stainless steel wire, and a steam tank provides steam protection to the quenching tube during the quenching process via the second steam delivery pipe. It also has the advantage of uniformly spraying a catalyst onto the outer surface of the stainless steel wire.

[0004] While the aforementioned cases demonstrate that continuous heating and cooling of the steel wire can impart good corrosion resistance and mechanical properties, significant deficiencies exist in the end-of-winding process. When the wire is almost fully wound and the end detaches from the heating furnace, the remaining wire length is short, and the unsupported end experiences violent, irregular swaying, leading to tangled, knotted, or even entangled strands on other equipment components. This severely impacts winding quality and the smooth operation of subsequent processes. At this point, operators often need to manually intervene, threading or pressing the wire at its high-speed movement. This is not only labor-intensive and dangerous but also makes it difficult to ensure the stability and consistency of end-of-winding treatment. Even if winding is successful, improper handling often leaves excessively long or irregular ends, resulting in material waste or affecting the neatness of the wound wire arrangement. Summary of the Invention

[0008] An elastic device is provided between the sliding frame and the heating furnace.

The elastic element between the sliding member and the auxiliary frame is provided to drive the sliding member to reset. An elastic element is provided between the sliding key and the auxiliary frame. The elastic element between the sliding key and the auxiliary frame is provided to drive the sliding key to move.

[0009] The support device includes a rotating rod rotatably connected to the auxiliary frame, a locking block fixedly connected to the rotating rod, and a fixed frame one fixed to the outer wall of the heating furnace. The surface of the fixed frame one is provided with a sliding groove, which matches the locking block.

[0010] The support device also includes a slide rod that slides on the inner wall of the first fixed frame, a second fixed frame that slides on the outer wall of the heating furnace, a connecting rod that rotatably connects the slide rod and the second fixed frame, and a fixing key that is fixed on the outer wall of the first fixed frame. The second fixed frame has a slot on the side near the fixing key, and the slot matches the fixing key.

[0011] A torsion spring is provided between the rotating rod and the auxiliary frame. The torsion spring is provided to drive the rotating rod to move toward the fixed frame. An elastic element is provided between the sliding rod and the fixed frame. The elastic element is provided between the sliding rod and the fixed frame to drive the sliding rod to return to its original position.

[0012] The prompting device includes a push plate fixed to the outer wall of the auxiliary frame, a stop member disposed on the outer wall of the heating furnace, a fixed plate fixedly connected to the stop member, a connecting rod sliding on the surface of the heating furnace, and a connecting rod rotatably connecting the stop member and the connecting rod. The stop member has a stop block on the side near the sliding frame, and the sliding frame has a resistance groove on the side near the stop block. The stop block matches the assist groove, and the fixed plate has an inclined surface on the side near the push plate.

[0013] The prompting device also includes a sliding rod that slides on the inner wall of the sliding frame, a fixing block that is fixed to the surface of the heating furnace, a push block that is fixedly connected to the sliding rod, a push rod that is fixedly connected to the sliding rod, a sliding rod that slides on the surface of the sliding frame, a tapping block that is fixedly connected to the sliding rod, and a tapping rod, wherein the tapping rod is rotatably connected to the inner wall of the pressure rod shaft.

[0014] The push block has an inclined surface on the side near the fixed block to facilitate the movement of the push block by the fixed block.

An elastic element is provided between the sliding rod and the sliding frame to drive the sliding rod to reset. A torsion spring is provided between the pressure rod and the striking rod to drive the striking rod to reset.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, when the end of the steel wire detaches from the heating furnace, the clamping rod automatically clamps the end of the steel wire and moves with the steel wire driven by the auxiliary frame. This effectively solves the problem of the end of the steel wire becoming uncontrollable and swinging violently due to insufficient length, avoids tangled or knotted wires at the end, eliminates the need for manual threading or pressing of the wire at the end, reduces the labor intensity of operators, and shortens the auxiliary time in the finishing stage. When the auxiliary frame extends to the predetermined position, the ball bearing aligns with the slot and engages, triggering the push plate to move the sliding part, thereby causing the clamping rod to automatically release the end of the steel wire, ensuring that the end of the steel wire can be completely wound up. This avoids the problem of the end remaining too long or unable to be wound up properly due to the clamp not being released. It does not rely on sensors or manual operation, which not only reduces equipment costs but also improves reliability and stability in harsh environments.

[0016] 2. In this invention, when the auxiliary frame extends, the rotating rod drives the locking block to insert into the sliding groove and clamp it tightly against the inner wall of the fixed frame, forming a stable mechanical locking structure. This effectively enhances the support strength of the auxiliary frame in the extended state, avoiding swaying or deformation caused by wire tension or its own weight, and ensuring the smooth and reliable clamping and follow-up process at the tail end. When the extension distance of the auxiliary frame further increases, the locking block pushes the sliding rod to move, and through the transmission of the connecting rod, it drives the fixed frame to clamp with the fixed key. This support mechanism further enhances the connection strength between the fixed frame and the heating furnace on the basis of the original support, so that the entire support system maintains extremely high rigidity and stability when the auxiliary frame is fully extended.

[0017] 3. In this invention, the linkage of the push plate, the fixed plate, the second connecting rod, and the connecting rod drives the resisting element to move towards the sliding frame and inserts the resisting block into the resistance groove. This mechanism generates controllable resistance to the movement of the sliding frame, effectively suppressing unnecessary fluctuations caused by the swing or vibration of the wire on the pressure rod, making the tension display more stable. When the wire stress exceeds the normal range, the upward movement of the pressure rod will cause the striking block to move onto the rotation path of the striking rod. When the striking rod rotates with the pressure rod, it will strike the striking block and make a sound, reminding the operator to reduce the winding speed in time to avoid wire breakage or product quality problems due to excessive stress.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 One embodiment of the present invention is: a heat treatment device for austenitic corrosion-resistant stainless steel wire, comprising: a heating furnace 1, a spraying device 2 for cooling the steel wire, a fan 3 for enhancing the cooling effect, a guide wheel 4 for guiding the winding of the heat-treated steel wire, a sliding frame 5 sliding on the outer wall of the heating furnace 1, and a pressure rod 6 rotating on the inner wall of the sliding frame 5. The spraying device 2 is fixedly connected to the heating furnace 1, the fan 3 is fixedly connected to the heating furnace 1, the guide wheel 4 is located at the bottom of the heating furnace 1, a sliding groove is provided on the inner wall of the heating furnace 1, and a round tube is provided on the outer wall of the sliding groove. The heat treatment device for corrosion-resistant stainless steel wire further comprises: an auxiliary device for assisting the tail end of the steel wire to detach after heat treatment, a support device for strengthening the support strength of the auxiliary device, and a warning device that emits a sound when the stress of the steel wire is too high. The auxiliary device includes an auxiliary frame 7 that slides on the inner wall of the heating furnace 1, a sliding member 9 that slides through the inner wall of the auxiliary frame 7, a clamping rod 8 that is fixedly connected to the sliding member 9, a pusher 10 that slides through the inner wall of the round tube, a locking key 11 that slides through the inner wall of the auxiliary frame 7, and a ball bearing 15 disposed on the inner wall of the pusher 10. The sliding member 9 is fixedly connected to the locking key 11. A slot is provided on the inner wall of the heating furnace 1 near the locking key 11, and the locking key 11 contacts the inner wall of the slot.

[0022] The auxiliary device also includes a sliding key 12 that slides through the outer wall of the auxiliary frame 7, a push plate 13 that is fixedly connected to the sliding key 12, and a ball bearing 14 disposed on the inner wall of the sliding key 12, the ball bearing 14 being in contact with the inner wall of the heating furnace 1.

[0023] An elastic device is provided between the sliding frame 5 and the heating furnace 1. The elastic device is provided to apply pressure to the steel wire through the sliding frame 5 and the pressure rod 6. An elastic element is provided between the sliding member 9 and the auxiliary frame 7. The elastic element between the sliding member 9 and the auxiliary frame 7 is provided to drive the sliding member 9 to reset. An elastic element is provided between the sliding key 12 and the auxiliary frame 7. The elastic element between the sliding key 12 and the auxiliary frame 7 is provided to drive the sliding key 12 to move.

[0024] In this embodiment, when heat treatment of stainless steel wire is required, the wire is pulled through the heating furnace 1 by a take-up reel. The furnace 1 heats the wire as it passes through. After the wire is pulled out, the spraying device 2 sprays coolant onto the wire surface to cool it. The fan 3 blows cold air onto the wire surface to enhance the cooling effect. The guide wheel 4 guides the pulled-out wire. After the wire is pulled out, the sliding frame 5 is pulled downwards by the elastic element. This downward movement of the sliding frame 5 moves the pressure rod 6, which presses down on the pulled-out wire. When the stress on the wire increases, it pushes the pressure rod 6 upwards, allowing the operator to more intuitively observe the stress changes. The wire exits the heating furnace 1... When the ball bearing 15 comes into contact with the heating element, the heating furnace 1 will push the ball bearing 15 to move. The movement of the ball bearing 15 will push the pusher 10 to move, which in turn will push the slider 9 to move. The movement of the slider 9 will cause the clamping rod 8 to move, and the movement of the slider 9 will cause the locking key 11 to move. The locking key 11 will then insert into the slot on the inner wall of the heating furnace 1, thus fixing the auxiliary frame 7. When the heating furnace 1 is about to be completely wound, it will disengage from the ball bearing 15, and the pusher 10 will release its push on the slider 9. The slider 9 will then move inward toward the auxiliary frame 7, causing the clamping rod 8 to move. The clamping rod 8 will then clamp the end of the wire. The movement of the slider 9 toward the auxiliary frame 7 will cause the locking key 11 to move, thus releasing the locking key 11's limit on the auxiliary frame 7. When clamping the wire, clamping rod 8 is pulled by the wire, which in turn moves auxiliary frame 7. Auxiliary frame 7 and clamping rod 8 will clamp the wire's end when it is too short and move with the wire, preventing violent swaying. As auxiliary frame 7 extends, it moves sliding key 12, which in turn moves ball bearing 14. When ball bearing 14 aligns with the slot, it moves towards the inner wall of the slot. Sliding key 12 moves push plate 13, which in turn moves sliding member 9 away from auxiliary frame 7. Sliding member 9 moves clamping rod 8. When auxiliary frame 7 extends a certain distance, clamping rod 8 releases its grip on the wire, allowing the wire to... When the wire is fully wound up and the end detaches from the heating furnace 1, the clamping rod 8 automatically clamps the wire end and moves with it, driven by the auxiliary frame 7. This effectively solves the problem of the wire end becoming uncontrollable and swinging violently due to insufficient length, preventing tangled or knotted wires at the end. It eliminates the need for manual threading or pressing of the wire at the end, reducing the labor intensity of operators and shortening the auxiliary time during the finishing stage. When the auxiliary frame 7 extends to the predetermined position, the ball bearing 14 aligns and engages with the slot, triggering the push plate 13 to move the sliding member 9, thereby causing the clamping rod 8 to automatically release the wire end. This ensures that the wire end is fully wound up, avoiding the problem of excessively long wire ends or inability to be wound up completely due to incomplete clamping. No sensors or manual operation are required.This not only reduces equipment costs but also improves reliability and stability in harsh environments.

[0025] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the support device includes a rotating rod 21 rotatably connected to the auxiliary frame 7, a locking block 22 fixedly connected to the rotating rod 21, and a fixing frame 23 fixed to the outer wall of the heating furnace 1. The surface of the fixing frame 23 is provided with a sliding groove, which matches the locking block 22.

[0026] The support device also includes a slide rod 24 that slides on the inner wall of the first fixed frame 23, a second fixed frame 25 that slides on the outer wall of the heating furnace 1, a connecting rod 26 that rotatably connects the slide rod 24 and the second fixed frame 25, and a fixing key 27 that is fixed on the outer wall of the first fixed frame 23. The second fixed frame 25 has a slot on the side near the fixing key 27, and the slot matches the fixing key 27.

[0027] A torsion spring is provided between the rotating rod 21 and the auxiliary frame 7. The torsion spring is provided to drive the rotating rod 21 to move toward the fixed frame 23. An elastic element is provided between the sliding rod 24 and the fixed frame 23. The elastic element between the sliding rod 24 and the fixed frame 23 is provided to drive the sliding rod 24 to return to its original position.

[0028] The prompting device includes a push plate 31 fixed to the outer wall of the auxiliary frame 7, a stop 33 set on the outer wall of the heating furnace 1, a fixing plate 32 fixedly connected to the stop 33, a connecting rod 35 sliding on the surface of the heating furnace 1, and a connecting rod 34 rotatably connecting the stop 33 and the connecting rod 35. The stop 33 is provided with a stop block on the side near the sliding frame 5, and the sliding frame 5 is provided with a resistance groove on the side near the stop block. The stop block matches the resistance groove. The side of the fixing plate 32 near the push plate 31 is provided with an inclined surface.

[0029] The prompting device also includes a sliding rod 36 that slides on the inner wall of the sliding frame 5, a fixing block 38 that is fixed on the surface of the heating furnace 1, a push block 37 that is fixedly connected to the sliding rod 36, a push rod 39 that is fixedly connected to the sliding rod 36, a sliding rod 391 that slides on the surface of the sliding frame 5, a striking block 392 that is fixedly connected to the sliding rod 391, and a striking rod 393. The striking rod 393 is rotatably connected to the inner wall of the rotating shaft of the pressure rod 6.

[0030] The push block 37 has an inclined surface on the side near the fixed block 38. The inclined surface of the push block 37 is to facilitate the movement of the push block 37 by the fixed block 38. The push rod 39 has an inclined surface on the side near the sliding rod 391. The inclined surface of the push rod 39 is to facilitate the movement of the sliding rod 391. An elastic element is provided between the sliding rod 36 and the sliding frame 5. An elastic element is provided between the sliding rod 391 and the sliding frame 5. The elastic element is provided to drive the sliding rod 391 to reset. A torsion spring is provided between the pressure rod 6 and the striking rod 393. The torsion spring is provided to drive the striking rod 393 to reset.

[0031] In this embodiment, when the auxiliary frame 7 extends, it drives the rotating rod 21 to move. As the rotating rod 21 moves away from the heating furnace 1, it rotates towards the fixed frame 23. The movement of the rotating rod 21 drives the locking block 22 to move, and the locking block 22 inserts into the sliding groove. After the locking block 22 is inserted into the sliding groove, the rotating rod 21 drives the locking block 22 to continue moving, and the locking block 22 will be locked against the inner wall of the fixed frame 23. The fixed frame 23 and the rotating rod 21 will strengthen the support of the auxiliary frame 7. When the rotating rod 21 pulls the locking block 22 to continue moving, it will contact the sliding rod 24. The locking block 22 will push the sliding rod 24 to move, and the movement of the sliding rod 24 will pull the connecting rod 26 to move. The movement of the connecting rod 26 will pull the fixed frame 25 to move towards the fixed key 27, and the fixed frame 25 will be locked against the fixed key 27. The second frame 25 strengthens the support between the first fixed frame 23 and the heating furnace 1. When the auxiliary frame 7 extends, the rotating rod 21 drives the locking block 22 to insert into the sliding groove and lock it with the inner wall of the first fixed frame 23, forming a stable mechanical locking structure. This effectively enhances the support strength of the auxiliary frame 7 in the extended state, avoiding swaying or deformation caused by wire tension or its own weight, and ensuring the smooth and reliable clamping and following process at the tail end. When the extension distance of the auxiliary frame 7 further increases, the locking block 22 pushes the sliding rod 24 to move. Through the transmission of the connecting rod 26, the second fixed frame 25 is locked with the fixing key 27. This support mechanism further enhances the connection strength between the first fixed frame 23 and the heating furnace 1 on the basis of the original support, so that the entire support system maintains extremely high rigidity and stability when the auxiliary frame 7 is fully extended.

[0032] When the auxiliary frame 7 moves, it will cause the push plate 31 to move. The push plate 31 will then contact the inclined surface of the fixed plate 32, which will push the fixed plate 32 to move. The movement of the fixed plate 32 will push the resist 33 to move. The movement of the resist 33 will cause the connecting rod 34 to move. The movement of the connecting rod 34 will push the connecting rod 35 to move. The movement of the connecting rod 35 will cause the resist 33 on the other side to move towards the sliding frame 5. The movement of the resist 33 towards the sliding frame 5 will cause the stop block to insert into the resistance groove. Thus, the resist 33 will generate resistance to the movement of the sliding frame 5, preventing the pressure rod 6 from moving with the steel wire. The oscillation of the wire causes fluctuations. When the stress generated by the wire is too great, it will push the pressure rod 6 upward. The movement of the pressure rod 6 will drive the sliding frame 5 to move, which in turn will drive the sliding rod 36 to move. The movement of the sliding rod 36 will drive the push block 37 to move. The push block 37 will then contact the inclined surface of the fixed block 38, which will push the push block 37 towards the pressure rod 6. The movement of the push block 37 will then drive the sliding rod 36 to move, which in turn will drive the push rod 39 to move. The push rod 39 will then contact the inclined surface of the sliding rod 391, which will then push the push rod 39 to move towards the pressure rod 6. This will push the sliding rod 391 to move towards the pressure rod 6. The movement of the sliding rod 391 will drive the striking block 392 to move. When the pressure rod 6 rotates, it will drive the striking rod 393 to rotate. When the striking block 392 moves downward, the moving striking rod 393 will strike the striking block 392 and produce a sound. When the stress on the steel wire is too high, the striking rod 393 will strike the striking block 392 and make a sound to remind the worker that the winding speed is too fast and the stress on the steel wire is too high. When the auxiliary frame 7 extends, through the linkage of the push plate 31, the fixing plate 32, the connecting rod 34 and the connecting rod 35, the resist 33 is driven. The mechanism moves towards the sliding frame 5 and inserts the stop block into the resistance groove. This mechanism generates controllable resistance to the movement of the sliding frame 5, effectively suppressing unnecessary fluctuations caused by the swing or vibration of the wire in the pressure rod 6, making the tension display more stable. When the wire stress exceeds the normal range, the upward movement of the pressure rod 6 will cause the striking block 392 to move onto the rotation path of the striking rod 393. When the striking rod 393 rotates with the pressure rod 6, it will strike the striking block 392 and make a sound, reminding the operator to reduce the winding speed in time to avoid wire breakage or product quality problems due to excessive stress.
