Description

Technical Field

[0001] This disclosure relates to the field of quenching equipment technology, and more particularly to a quenching equipment for a steel bar production line. Background Technology

[0002] In existing steel bar production, quenching is typically required to enhance the strength of the steel bars. The quenching device in a steel bar production line is the core cooling unit of a continuous heat treatment production line. Its core function is to rapidly and uniformly cool the steel bars heated to the austenitizing temperature, achieving martensitic transformation and obtaining a high-hardness, high-strength surface or overall microstructure. Most existing steel bar quenching devices involve spraying or directly immersing the steel bars for quenching. However, due to the relatively long length of the steel bars, uneven temperature distribution is common during quenching, leading to bending. Furthermore, the contact between the cooler liquid and the hotter steel bar during quenching generates a large amount of steam. This steam can easily affect the surrounding environment and equipment, and the high pressure during quenching or the low pressure after cooling can negatively impact the steel bars themselves, affecting the production quality.

[0020] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figures 1 to 12As shown in the present disclosure, an embodiment of a steel bar production line quenching device is provided, comprising: a base 101, a quenching liquid tank 102 fixed on the periphery of the base 101, a circulation structure installed inside the quenching liquid tank 102, a recovery chamber 107 opened inside the base 101, the recovery chamber 107 being connected to the circulation structure, a filter structure installed inside the recovery chamber 107, the filter structure including a filter plate 108 snapped and fixed inside the recovery chamber 107; and an immersion quenching structure, the immersion quenching structure including multiple immersion chambers 201 opened inside the base 101, a top cover 203 installed on the top of the immersion chamber 201, a water spray head 204 installed inside the top cover 203, a support plate 205 installed on the bottom of the immersion chamber 201, multiple support blocks 206 fixed on the support plate 205, and the immersion chambers 201 and the recovery chamber 107 being connected. The system includes a spray quenching structure, comprising a spray frame 401, a support base 301 fixed on a base 101, a rotation drive structure mounted on the support base 301, a push structure between the rotation drive structure and the spray frame 401, the push structure including a first telescopic rod 308, a heat exchange structure inside the spray frame 401, the heat exchange structure including a heat exchange tube 404, multiple auxiliary support structures mounted on the heat exchange tube 404, the auxiliary support structures including multiple second telescopic rods 407, the ends of the second telescopic rods 407 being rotatably fitted with support balls 413; and a clamping structure, comprising a top plate 501 located on the upper side of the spray frame 401, multiple clamping frames 508 slidably fitted on the lower side of the top plate 501, and steel bars 507 installed between the multiple clamping frames 508.

[0022] Specifically, this application relates to a quenching equipment for processing steel used in fasteners in the automotive and wind power industries, steel used in high-performance machine tool guideways and other components, and steel used in high-performance tunneling machine tools. The equipment utilizes a circulation structure to circulate the quenching fluid, ensuring its temperature remains low. A filter plate 108 filters the circulating quenching fluid, preventing larger debris from clogging the circulation structure and extending the equipment's lifespan. The quenching fluid can be recycled, reducing waste. Spray quenching is performed via a spray frame 401, and immersion quenching via a soaking chamber 201, thus improving quenching efficiency while ensuring uniform quenching temperature. This, in turn, increases the production efficiency of the steel bars 507. The produced steel bars 507 are high-strength cord steel products suitable for applications in the automotive and wind power industries, as well as in high-performance machine tool guideways and high-performance tunneling machine tools.

[0023] In this embodiment, the circulation structure includes: a first liquid pump 103 and a second liquid pump; wherein, the first liquid pump 103 is fixed on the quenching liquid tank 102, the inlet end of the first liquid pump 103 is fixed with a suction pipe 104, the end of the suction pipe 104 is fixed with a connecting head 106, the connecting head 106 is connected to the recovery chamber 107, and the outlet end of the first liquid pump 103 is connected to the quenching liquid tank 102; wherein, the second liquid pump is fixed inside the quenching liquid tank 102, a plurality of connecting pipes 105 are opened in the base 101, the inlet end of the second liquid pump is connected to the quenching liquid tank 102, the outlet end of the second liquid pump is connected to the connecting pipes 105, a plate cooler is installed inside the quenching liquid tank 102, a connecting port 109 is opened between the immersion chamber 201 and the recovery chamber 107, the connecting port 109 is located on the upper side of the filter plate 108, and an electric valve 110 is installed inside the connecting port 109.

[0024] Specifically, starting the first liquid pump 103 allows the quenching liquid, filtered by the filter plate 108, to be drawn from the recovery chamber 107 and returned to the quenching liquid tank 102. After cooling by the plate cooler, starting the second liquid pump allows the cooled quenching liquid to be drawn out and sent into the connecting pipe 105. The cooled quenching liquid then enters the immersion chamber 201 for immersion quenching, thus achieving a better quenching effect and reducing the waste of quenching liquid. After quenching, the quenching liquid enters the recovery chamber 107 through the connecting port 109, is filtered by the filter plate 108, and is then drawn out, achieving a better circulation effect, reducing the waste of quenching liquid, preventing quenching liquid blockage, and preventing a large number of impurities in the quenching liquid from affecting the quenching process, thus ensuring the processing quality of the steel bar 507.

[0025] The immersion quenching structure also includes: multiple ball bearings 202, which are rotatably fitted within the wall of the immersion chamber 201; the top of the immersion chamber 201 has a square structure; a top cover 203 is rotatably fitted within the top of the immersion chamber 201; a torsion spring is installed between the top cover 203 and the wall of the immersion chamber 201; and a water spray head 204 is connected to a connecting pipe 105. The base 101 has multiple discharge ports 209 at its bottom, which are connected to the immersion chamber 201. Multiple limiting blocks 208 are fixed at the bottom of the immersion chamber 201. An electric lock 207 is installed in the immersion chamber 201 and is locked to the support plate 205.

[0026] Specifically, when the steel rod 507 enters the soaking chamber 201, it will press down on the top cover 203, allowing it to fall into the soaking chamber 201. Once the steel rod 507 is fully inside the soaking chamber 201, the top cover 203 resets under the action of a torsion spring. Then, quenching fluid is added through the spray nozzle 204 inside the top cover 203, and flows out through the connecting port 109 to form a circulation, thus ensuring the quenching effect on the steel rod 507. Furthermore, the support block 206 and the ball bearing 202 reduce the contact area between the steel rod 507 and other structures, ensuring uniform temperature of the steel rod 507, guaranteeing the production and processing quality of the steel rod 507, and preventing the steel rod 507 from bending due to large-area contact with other structures, thereby ensuring the pass rate of the steel rod 507.

[0027] The rotation drive structure includes: a first motor 305, which is fixed to the base 101. A gear 306 is fixed to the output end of the first motor 305. A rotating frame 302 is rotatably fitted on the support base 301. A rotating groove 303 is provided on the support base 301, and the rotating frame 302 is located in the rotating groove 303. Multiple teeth 304 are fixed on the periphery of the rotating frame 302, and the teeth 304 mesh with the gear 306. The first telescopic rod 308 includes: a first rod body 309 and a second rod body 310. 309 is fixedly connected to the rotating frame 302. The first rod 309 is a hollow structure. The first rod 309 is slidably connected to the second rod 310. The rotating frame 302 has a first air chamber 307, which is connected to the first rod 309. One end of the second rod 310 located inside the first rod 309 is fixed with a first piston plate 311. The first piston plate 311 is in contact with the inner wall of the first rod 309. The other end of the second rod 310 is fixed with a connecting frame 312, which is fixedly connected to the spray frame 401.

[0028] Specifically, starting the first motor 305 drives the gear 306 to rotate, which in turn meshes with the teeth 304, causing the rotating frame 302 to rotate. This, in turn, drives the spray frame 401 to rotate. When air is introduced into the first air chamber 307, the change in air pressure in the first rod 309 pushes the second rod 310 to move, which in turn moves the spray frame 401. When the spray frame 401 is eccentric, the rotation of the rotating frame 302 can move the spray frame 401 to any position, allowing it to move from above the recovery chamber 107 to above the soaking chamber 201. This allows the sprayed steel rod 507 to be sent into the soaking chamber 201, enabling spray quenching and soaking quenching of the steel rod 507. This ensures the quenching effect of the steel rod 507, and the two steps are performed separately, quenching only one steel rod 507 at a time, improving the production quality of the steel rod 507 and increasing work efficiency.

[0029] The spray quenching structure also includes: multiple spray nozzles 403, which are opened on the periphery inside the spray frame 401. A cavity 402 is opened inside the spray frame 401, which is connected to the spray nozzles 403. A water inlet pipe is fixed on one side of the cavity 402. The spray frame 401 is located on the upper side of the recovery chamber 107.

[0030] Specifically, the water inlet pipe can be connected to the second liquid pump, and quenching liquid can be sent into the cavity 402 through the water inlet pipe, and then sprayed out from the spray nozzle 403 to quench the periphery of the steel bar 507, ensuring the uniformity of spray quenching, thereby improving the production quality of the steel bar 507.

[0031] The heat exchange structure also includes: an inlet pipe 405 and an outlet pipe 406; wherein, the inlet pipe 405 is fixed to the top of the spray frame 401, and the outlet pipe 406 is fixed to the bottom of the spray frame 401. A second air chamber 414 is provided at both the top and bottom of the spray frame 401, and the second air chamber 414 is connected to the inlet pipe 405, the outlet pipe 406, and the heat exchange pipe 404. The second telescopic rod 407 includes: a third rod body 408 and a fourth rod body 409; wherein, the third rod body 408 is a hollow structure, and the third rod body 408 is connected to the heat exchange pipe 404. 04 are connected, the third rod 408 and the fourth rod 409 are slidably connected, one end of the fourth rod 409 located inside the third rod 408 is fixed with a second piston plate 410, the second piston plate 410 is in contact with the inner wall of the third rod 408, and the support ball 413 is rotatably engaged with the other end of the fourth rod 409, the support ball 413 is in contact with the steel rod 507; wherein, the third rod 408 is provided with a connecting groove 411, and the end of the third rod 408 is provided with a plurality of air holes 412, the air holes 412 being connected to the connecting groove 411.

[0032] Specifically, heat exchange gas is introduced into the heat exchange tube 404 through the air inlet pipe 405 for heat exchange. The gas is recovered through the air outlet pipe 406, and a portion of the gas enters the third rod 408, thereby pushing the fourth rod 409. This causes the support ball 413 to contact the steel rod 507, supporting the steel rod 507. The steel rod 507 can also push the fourth rod 409 in the opposite direction. The air pressure ensures the stability of the fourth rod 409 and the steel rod 507, preventing the steel rod 507 from contacting the inner wall of the spray frame 401. When the steel rod 507 falls into the soaking chamber 201, the air pressure pushes the fourth rod 409 to move, causing the second piston plate 410 to enter the connecting groove 411. At this time, the gas can be blown out through the air hole 412 into the spray frame 401, preventing the temperature inside the spray frame 401 from getting too low and causing the air pressure to drop. This prevents the spray frame 401 from deforming and extends the service life of the device.

[0033] The clamping structure also includes: a second motor 503, which is fixed on the top plate 501. A sliding groove 502 is provided in the top plate 501. The clamping frame 508 is slidably engaged in the sliding groove 502. A screw 504 is rotatably engaged in the sliding groove 502. The output end of the second motor 503 is fixedly connected to the screw 504. The screw 504 is threadedly engaged with the clamping frame 508. The clamping structure also includes: multiple clamping blocks 505. The clamping blocks 505 are conical in shape. The clamping blocks 505 are fixedly connected to the clamping frame 508 and are in contact with the steel rod 507. A guide rod 506 is fixed on the lower side of the top plate 501 and is located on the upper side of the steel rod 507.

[0034] Specifically, when it is necessary to clamp and fix the steel bar 507, the second motor 503 is started, which drives the screw 504 to rotate. This causes multiple clamping frames 508 to move closer to each other until the clamping block 505 contacts the steel bar 507. This provides a good clamping effect on the steel bar 507. Furthermore, the small contact area between the steel bar 507 and the clamping block 505 facilitates the flow of quenching liquid, ensures the quenching effect, prevents deformation of the steel bar 507, and thus guarantees the processing quality of the steel bar 507.

[0035] Workflow: The second motor 503 is started, causing the screw 504 to rotate. This causes multiple clamping frames 508 to move closer together until the clamping block 505 contacts the steel rod 507, thus achieving a better clamping effect on the steel rod 507. Then, the steel rod 507 is sent into the spray frame 401 by a crane. The water inlet pipe is connected to the second liquid pump, and quenching liquid is sent into the cavity 402 through the water inlet pipe. Then, it is sprayed out from the spray nozzle 403, which quenches the periphery of the steel rod 507. Heat exchange gas is introduced into the heat exchange tube 404 through the air inlet pipe 405 for heat exchange. The gas is recovered through the air outlet pipe 406, and some of the gas enters the third rod 408, thereby pushing the fourth rod 409, causing the support ball 41 to move. 3. The air rod 507 is in contact with the steel rod 507 to support it, and the steel rod 507 can also push the fourth rod 409 to move in the opposite direction. The stability of the fourth rod 409 is ensured by air pressure, which in turn ensures the stability of the steel rod 507 and prevents the steel rod 507 from contacting the inner wall of the spray frame 401. The sprayed quenching liquid flows into the recovery chamber 107 for recovery. Then, the first motor 305 is started, which drives the gear 306 to rotate. The gear 306 meshes with the teeth 304, causing the rotating frame 302 to rotate, thereby driving the spray frame 401 to rotate. When air is vented into the first air chamber 307, the change in air pressure in the first rod 309 pushes the second rod 310 to move, thereby pushing the spray frame 401 to move. When the spray frame 401 is eccentric, the rotating frame 302 rotates, which can move the spray frame 401 to any position, allowing it to move from above the recovery chamber 107 to above the soaking chamber 201. This allows the sprayed steel rod 507 to be sent into the soaking chamber 201. When the steel rod 507 enters the soaking chamber 201, it will press down on the top cover 203, causing it to fall into the soaking chamber 201. After the steel rod 507 is fully inside the soaking chamber 201, the top cover 203 returns to its original position under the action of a torsion spring. Then, quenching fluid is added through the spray head 204 inside the top cover 203, and flows out through the connecting port 109 to form a circulation, thus ensuring the quenching effect on the steel rod 507. The support block 206 and the ball bearing 202 can reduce the contact area between the steel bar 507 and other structures, thereby ensuring the uniformity of the temperature of the steel bar 507. Starting the first liquid pump 103 allows the quenching liquid, filtered by the filter plate 108, to be drawn from the recovery chamber 107 and returned to the quenching liquid tank 102. After cooling by the plate cooler, starting the second liquid pump allows the cooled quenching liquid to be drawn out and sent into the connecting pipe 105. The cooled quenching liquid then enters the immersion chamber 201 for immersion quenching, achieving a better quenching effect and reducing quenching liquid waste. The quenched quenching liquid enters the recovery chamber 107 through the connecting port 109, is filtered by the filter plate 108, and then extracted.This achieves a good circulation effect. After quenching, the support plate 205 can be manually removed, allowing the steel bar 507 to slide downwards, thus completing the collection of the steel bar 507.
