Description

Technical Field

[0001] This invention relates to the field of heat treatment technology for tire bead wires, and more particularly to a heat treatment device for tire bead wires. Background Technology

[0002] Tire bead wire is one of the core skeleton materials of radial tires. Its performance directly determines the tire's strength and service life. Heat treatment equipment is the key equipment to ensure the performance of bead wire. Bead wire heat treatment equipment is mainly used to heat and quench high-carbon bronze-plated steel wire. By controlling the internal metal crystal structure of the steel wire, the internal stress generated during the production process is eliminated, and the strength, toughness and yield strength ratio of the steel wire are improved. This allows the steel wire to bond well with rubber and meet the requirements of tire bead use. It is widely used in the steel wire processing process of the tire manufacturing industry.

[0003] Chinese patent CN119162446B discloses a heat treatment device for high yield strength ratio tire bead wire. The device includes a heat treatment support assembly and a heat treatment component. A base is provided on one side of the heat treatment support assembly, and a pair of horizontally placed crossbeams are connected to the top of the base. The heat treatment component is installed between the two crossbeams. The device transports the wire through a heating roller. An external electric heating plate at the top of the inner cavity of the upper heating hood provides the main heating for the wire. An electric heating controller controls the inner electric heating plate to heat the heating roller, providing auxiliary heating for the wire to improve efficiency. When the wire is transported to the bottom of the heating roller, it is immersed in the quenching liquid in the inner cavity of the lower heating hood to complete the quenching treatment, which improves the practicality of the heat treatment to a certain extent.

[0004] While the aforementioned existing technology possesses certain heating and quenching effects, it exhibits significant drawbacks in practical applications. During quenching, this device primarily relies on a single-sided spray nozzle to spray quenching liquid onto the outer surface of the steel wire. However, the steel wire moves at a relatively high speed, resulting in a short contact time with the quenching liquid, which can easily lead to incomplete contact. Furthermore, the spray nozzle can only effectively coat the side of the steel wire closest to the nozzle, while the side furthest from the nozzle only receives sporadic application of quenching liquid. This prevents the quenching liquid from achieving a comprehensive and uniform coverage of the steel wire's outer surface, leading to uneven quenching of the steel wire. This affects the formation of its sorbite structure and mechanical properties, potentially reducing the quality stability of subsequent tire bead materials, thus limiting its application. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a heat treatment device for tire bead wires, which can more accurately solve the problems described above.

No additional power mechanism is required, simplifying the overall structure of the equipment and reducing energy consumption. While the drive mechanism drives the electric heating roller to rotate, the linkage mechanism drives the movable plate to move back and forth, thereby driving the quenching liquid spraying mechanism to move in conjunction. With the dual heating effect of the electric heating mechanism and the electric heating roller, the heating efficiency of the steel wire can be improved, and the steel wire can be heated evenly to meet the needs of subsequent quenching processing. Through the coordinated cooperation of various mechanisms, continuous conveying and uniform heating of steel wire can be achieved, improving processing efficiency and quenching quality. 2. During the application of this technical solution, the circulation mechanism, in conjunction with the quenching liquid spraying mechanism, enables the recycling of the quenching liquid during use, reducing quenching liquid loss and lowering material costs during processing. While the movable plate drives the quenching liquid spraying mechanism to reciprocate, the linkage module drives the slip ring and annular pipe to rotate, allowing the quenching liquid nozzles to spray the quenching liquid onto the steel wire from various angles. This ensures the outer surface of the steel wire is fully and evenly covered with the quenching liquid, improving the quenching effect and enabling the steel wire to achieve the required mechanical properties. Simultaneously, the use of a feeding guide mechanism and a discharging guide mechanism prevents the steel wire from shifting, scratching, or deforming during entry and exit from the equipment, reducing material loss during processing and ensuring that the processed steel wire meets production requirements, further enhancing the continuity of processing.

Electric heating rollers 23 are rotatably connected to the upper end of one side and the lower end of the other side of the heat treatment box 21. A drive mechanism 24 is fixedly installed on the front of the heat treatment box 21. A linkage mechanism 25 is fixedly installed on the top of the heat treatment box 21. The drive mechanism 24 and the linkage mechanism 25 are connected by transmission. A feed slot 26 is opened on the side of the heat treatment box 21 away from the quenching device 3. The quenching device 3 includes a quenching box 31, which is connected to a heat treatment box 21. A discharge chute 32 is provided at the upper end of the side of the quenching box 31 away from the heat treatment box 21. The steel wire 9 to be treated enters the heat treatment box 21 and the quenching box 31 through the feed chute 26 and is discharged through the discharge chute 32. A circulation mechanism 33 is fixedly installed at the bottom of the quenching box 31. Quenching liquid spraying mechanisms 34 are fixedly installed at equal intervals in a linear arrangement at the top of the quenching box 31. By cooperating with the heat treatment device 2 and the quenching device 3, the steel wire 9 to be treated can enter the heat treatment box 21 through the feed chute 26 during use. The electric heating mechanism 22 and the electric heating roller 23 inside the heat treatment box 21 work together to heat the steel wire. After heating, the steel wire enters the quenching box 31, which is connected to the heat treatment box 21. The circulation mechanism 33 at the bottom of 31 provides quenching fluid to the quenching fluid spraying mechanism 34. The quenching fluid spraying mechanism 34 quenches the heated steel wire. After quenching, the steel wire is discharged through the discharge trough 32. The drive mechanism 24 is connected to the linkage mechanism 25, which can drive the electric heating roller 23 to operate to realize the transmission of steel wire during use. At the same time, the linkage mechanism 25 can cooperate with the quenching device 3. The circulation mechanism 33 and the quenching fluid spraying mechanism 34 can achieve a stable supply of quenching fluid. The electric heating mechanism 22 and the electric heating roller 23 can improve the heating efficiency of steel wire. The heat treatment device 2 and the quenching device 3 can realize continuous processing of steel wire from heating to quenching, reduce the interruption of processing links, reduce processing costs, and at the same time ensure the effect of steel wire heating and quenching to meet production needs.

[0022] Combination Figures 1-5 As shown, the outer surface of the electric heating roller 23 is provided with annular receiving grooves 4 arranged linearly at equal intervals. The steel wire 9 to be treated is placed inside the annular receiving grooves 4. A feeding guide frame 5 is fixedly installed on the outside of the feeding slot 26 on the heat treatment box 21.

The upper and lower ends of the discharge guide frame 7 are rotatably connected to the discharge guide rollers 8.

[0023] The technical solutions in the above-described embodiments of this application, by setting an annular receiving groove 4 on the outer surface of the electric heating roller 23, allow the steel wire 9 to be processed to be placed in the annular receiving groove 4 during use, which can prevent multiple steel wires from tangling together during the conveying process. By setting a feeding guide frame 5 and a feeding guide roller 6, the steel wire 9 to be processed can be guided when entering the feeding slot 26, preventing the steel wire from deviating and failing to enter the heat treatment box 21 smoothly. By setting a discharge guide frame 7 and a discharge guide roller 8, the steel wire after quenching can be guided when exiting the discharge slot 32, preventing the steel wire from being scratched or deviating during the discharge process. The annular receiving groove 4 can limit the position of each steel wire 9 to be processed, so that the steel wire can stably adhere to the electric heating roller 23 for conveying and heating. The feeding guide roller 6 and the discharge guide roller 8 can reduce the friction between the steel wire and the guide frame, reduce the wear on the surface of the steel wire, thereby reducing material loss during the processing, ensuring the appearance and performance of the processed steel wire, and meeting the production requirements.

[0025] The technical solution in the above-described embodiments of this application, by setting up a drive mechanism 24, a linkage mechanism 25, and an electric heating mechanism 22 in cooperation, allows the drive motor 2422 to drive the lower synchronous pulley 2424 to rotate via a coupling during use. The lower synchronous pulley 2424 drives the upper synchronous pulley 2423 to rotate via a synchronous belt 2425, thereby driving the two electric heating rollers 23 to operate.

[0026] Combination Figures 1-7As shown, the circulation mechanism 33 includes a collection hopper 331, which is fixedly installed at the bottom of the quenching box 31. A circulation pump 332 is fixedly installed at the bottom of the collection hopper 331. The input end of the circulation pump 332 is connected to the interior of the quenching box 31. A delivery pipe 333 is fixedly installed at the output end of the circulation pump 332. Flexible hoses 334 are fixedly installed at equal intervals in a linear arrangement at the output end of the delivery pipe 333. The output end of each flexible hose 334 is connected to a corresponding quenching liquid spraying mechanism 34. The molten metal spraying mechanism 34 includes side ring rails 341 and a linkage module 342. The side ring rails 341 are fixedly installed at equal intervals on the upper side of the quenching box 31 near the heat treatment box 21. The side ring rails 341 are all located at the connection between the quenching box 31 and the heat treatment box 21. The steel wire 9 to be treated passes through the inner side of the side ring rails 341. A slip ring 343 is rotatably connected inside the side ring rails 341. The linkage module 342 is located on the top of the quenching box 31. The slip ring 343 transmits power through the linkage module 342 and the movable plate 253. The sliding ring 343 is fixedly installed with an annular pipe 344 on the side away from the heat treatment chamber 21. The output end of the hose 334 is connected to the annular pipe 344 at the corresponding position. Quenching liquid nozzles 345 are fixedly installed in a ring at equal intervals on the side of the annular pipe 344 away from the heat treatment chamber 21. Quenching liquid nozzles 346 are fixedly installed in a linear arrangement at equal intervals on the side of the quenching liquid nozzles 345 that are close to each other. The linkage module 342 includes a toothed ring 3421 and a connecting arm 3422. The toothed ring 3421 is fixedly connected to the side of the movable plate 253 near the quenching box 31. The toothed ring 3421 is fixedly installed on the outside of the slip ring 343. The connecting arm 3422 is fixedly installed with a slide bar 3423 at one end near the quenching box 31. The bottom of the slide bar 3423 is fixedly installed with a rack 3424. The rack 3424 and the toothed ring 3421 are meshed and connected. The top two ends of the quenching box 31 near the heat treatment box 21 are fixedly installed with support rails 3425. The two ends of the slide bar 3423 slide on the inside of the support rails 3425.

[0027] The technical solution in the above-described embodiment of this application, by setting up a circulation mechanism 33 in conjunction with a quenching liquid spraying mechanism 34, allows the collection hopper 331 to collect the quenching liquid in the quenching box 31 during use. The circulation pump 332 extracts the quenching liquid from the collection hopper 331 and transports it through the delivery pipe 333 to each hose 334. The hoses 334 then transport the quenching liquid to the annular pipe 344. The annular pipe 344 sprays the quenching liquid onto the steel wire 9 to be treated, which is inserted inside the side annular rail 341, through the quenching liquid spray pipe 345 and the quenching liquid nozzle 346. When the movable plate 253 moves, it drives the connecting arm 3422 and the slide bar 3423 to move. The slide bar 3423 slides within the support rail 3425. The rack 3424 at the bottom of the slide bar 3423 meshes with the toothed ring 3421, thereby driving the slip ring 343 to rotate within the side annular rail 341. The slip ring 343 then drives the annular pipe. The synchronous rotation of 344 allows the quenching liquid nozzle 346 to spray quenching liquid onto the steel wire from different angles. The collection hopper 331 can recycle the used quenching liquid, avoiding waste. The circulation pump 332, together with the delivery pipe 333 and hose 334, can achieve stable delivery of quenching liquid, ensuring that the quenching liquid spraying mechanism 34 continuously receives quenching liquid. The side ring rail 341 supports the slip ring 343, making the slip ring 343 rotate smoothly. The linkage module 342, together with the movable plate 253, can drive the slip ring 343 and the annular pipe 344 to rotate, allowing the quenching liquid to evenly cover the surface of the steel wire, reducing uneven quenching of the steel wire. The sliding bar 3423 slides within the support rail 3425, preventing the sliding bar 3423 from deviating and providing auxiliary support, ensuring smooth transmission of the linkage module 342, thereby reducing failures during processing and reducing material and energy consumption.

[0028] The operating principle and advantages of this invention are as follows: During application, the steel wire 9 to be treated is first aligned with the feeding guide frame 5. The feeding guide roller 6 guides the steel wire, allowing it to enter the heat treatment chamber 21 through the feeding slot 26. After entering the heat treatment chamber 21, the steel wire 9 is mounted on the outer surface of the electric heating roller 23. The annular receiving groove 4 limits the steel wire, preventing multiple steel wires from tangling or shifting, ensuring that each steel wire can fully contact the electric heating roller 23. The drive motor 2422 is started, and the drive motor 2422 drives the lower synchronous pulley 2424 to rotate through the coupling. The lower synchronous pulley 2424 drives the upper synchronous pulley 2423 to rotate synchronously through the synchronous belt 2425, thereby driving the two electric heating rollers 23 to rotate synchronously, achieving stable transmission of the steel wire 9 to be treated. At the same time, the electric heating mechanism 22 starts working, and the mounting base... 221 serves to fix and protect the heating wire 223. When the heating wire 223 is energized, it generates heat to heat the inside of the heat treatment box 21. Combined with the heating function of the electric heating roller 23, it provides double heating for the steel wire 9 to be treated during the conveying process. When the upper synchronous wheel 2423 rotates, the transmission bevel gear 2412 on its front rotates synchronously. The transmission bevel gear 2412 meshes with the driven bevel gear 2415, thereby driving the rotating shaft 2414 to rotate. The rotating shaft 2414 drives the turntable 252 to rotate. The turntable 252 drives the drive plate 256 to rotate. The drive plate 256 drives the linkage plate 255 to swing. The linkage plate 255 drives the movable plate 253 to reciprocate inside the top rail 251 through the hinge arm 254, realizing the synchronous linkage between the linkage mechanism 25 and the drive mechanism 24, and providing power for the quenching process.

[0029] After the steel wire 9 to be processed is heated in the heat treatment box 21, it enters the quenching box 31. At this time, the circulation mechanism 33 starts to work. The collection hopper 331 collects the quenching liquid after quenching. The circulation pump 332 draws out the quenching liquid in the collection hopper 331 and delivers it to each hose 334 through the delivery pipe 333. The hoses 334 deliver the quenching liquid to the quenching liquid spraying mechanism 34. During this period, due to the auxiliary linkage of the linkage mechanism 25, its linkage plate 255 can pull the movable plate 253 to move back and forth. The reciprocating movement of the movable plate 253 can drive the connecting arm 3422 on one side to move synchronously. The slide bar 3423 at one end of the connecting arm 3422 slides inside the support rail 3425. The rack 3424 at the bottom of the slide bar 3423 meshes with the toothed ring 3421, thereby driving the slip ring 343 to rotate inside the side ring rail 341. The slip ring 343 drives the annular pipe 3 The annular pipe 344, rotating synchronously, guides the quenching fluid from the hose 334 into the annular pipe 344. The quenching fluid spray nozzle 345 sprays the quenching fluid onto the surface of the steel wire 9 to be treated through the quenching fluid nozzle 346. Since the slip ring 343 drives the annular pipe 344 to rotate synchronously, and there are multiple quenching fluid spray nozzles 345, the small-amplitude reciprocating rotation of the slip ring 343 allows each quenching fluid nozzle 346 to spray the steel wire from various angles, ensuring that the quenching fluid stably and comprehensively quenches the steel wire 9 to be treated. Furthermore, the movable plate 253 drives the entire quenching fluid spraying mechanism 34 to move back and forth, rather than rotating continuously, so the hose 334 will not become entangled. After the steel wire 9 to be treated is quenched, it is discharged through the discharge trough 32. The discharge guide roller 8 guides the quenched steel wire to ensure that the steel wire is discharged smoothly, completing the entire heat treatment process.

[0030] During application, this device features a feeding guide frame 5 and a feeding guide roller 6, which prevents deviation and jamming when the steel wire enters, ensuring smooth subsequent processing. The annular receiving groove 4 prevents multiple steel wires from tangling or shifting during transport, ensuring each wire makes full contact with the electric heating roller 23, allowing for simultaneous processing of multiple wires. The dual heating structure improves heating efficiency, ensuring uniform heating of the steel wires and meeting the requirements for uniform quenching. The drive mechanism 24 and linkage mechanism 25 are synchronized, eliminating the need for an additional power mechanism, simplifying the overall equipment structure, and reducing energy consumption. The circulation mechanism 33 enables the recycling of quenching fluid, reducing quenching fluid loss and lowering material costs during processing. The support rail 3425... The sliding bar 3423 moves smoothly, allowing the quenching liquid spraying mechanism 34 to move and rotate more smoothly. The hose 334 swings back and forth with the movable plate 253, preventing the hose 334 from getting tangled and ensuring the smooth progress of the quenching process. The rotatable and reciprocating quenching liquid spraying structure can ensure that the outer surface of the steel wire is fully and evenly covered with quenching liquid, improving the quenching effect and allowing the steel wire to achieve the required mechanical properties. The discharge guide frame 7 and discharge guide roller 8 can prevent the steel wire from being scratched or deformed during the discharge process, ensuring that the processed steel wire meets the quality requirements. The cooperation of each structure can not only realize the continuous processing of steel wire, but also solve the core defects of the existing technology, improve processing efficiency and quality, and further reduce processing costs. The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here.

They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.
