Description
Technical Field
[0001] The utility model belongs to the technical field of roll quenching, and particularly relates to a surface quenching device for the production of high-speed steel rolls. Background Technique
[0002] High-speed steel rolls are the hot-rolled roll materials with the shortest appearance time, the fastest development, and the widest application prospects. High-speed steel, also known as air-hardening steel or high-speed steel, means that it can harden even when cooled in air during quenching and is very sharp. It is a complex alloy steel containing carbide-forming elements such as tungsten, molybdenum, chromium, and vanadium. The total amount of alloying elements reaches about 10% - 25%.
[0003] The quenching process of traditional high-speed steel rolls mainly includes several steps such as heating, holding, cooling in a quenching medium, and tempering. Before heating, it is usually necessary to transfer the high-speed steel rolls to a specific area for processing. During the transfer process, the high-speed steel rolls will shake, and the high-speed steel rolls will collide with the connected equipment, resulting in damage to the equipment. At the same time, the transfer speed of the high-speed steel rolls is reduced, indirectly reducing the quenching efficiency. For this reason, we provide a surface quenching device for the production of high-speed steel rolls to solve the above problems. Summary of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0027] For the first specific embodiment, please refer to Figures 1-5 , the present invention is a surface quenching device for the production of high-speed steel rolls, including a quenching tank 1, a clamping assembly 2, a power driving assembly 4 and a cooling assembly 5.

The power driving assembly 4 is installed on one side of the clamping assembly 2, the power driving assembly 4 includes an L-shaped moving plate 401, a driving rack 402 is installed on one side of the L-shaped moving plate 401, the cooling assembly 5 is installed on one side of the quenching tank 1 close to the power driving assembly 4, the cooling assembly 5 includes a cooling tank 501, and the cooling tank 501 is slidably connected to the L-shaped moving plate 401. A hydraulic cylinder 101 is installed at the bottom of the quenching tank 1, and the output end of the hydraulic cylinder 101 penetrates into the interior of the quenching tank 1 and is fixedly connected to the bottom of the support plate 201.
[0028] Specifically, the clamping assembly 2 further includes a first clamping plate 203 and a second clamping plate 204 that are slidably arranged on the top of the support plate 201. The high-speed steel roll 3 is located between the first clamping plate 203 and the second clamping plate 204. Positioning plates 205 are fixedly arranged on the tops of both the first clamping plate 203 and the second clamping plate 204. A first motor 206 is installed on one side of the positioning plate 205 at the top of the second clamping plate 204. The output shaft of the first motor 206 penetrates through the corresponding positioning plate 205 and is fixedly connected to a bidirectional threaded rod 207. The positioning plates 205 are in threaded cooperation through the bidirectional threaded rod 207.
[0029] Positioning ports 208 are formed on the surfaces of both the first clamping plate 203 and the second clamping plate 204. The two ends of the high-speed steel roll 3 are coaxially arranged with the corresponding positioning ports 208. A plugging ring 209 is rotatably arranged on the outside of the first clamping plate 203. A first connecting plate is fixedly arranged on one side of the plugging ring 209. Protruding blocks are arranged on the inner wall of the plugging ring 209. A groove is arranged at one end of the high-speed steel roll 3 close to the plugging ring 209. When the high-speed steel roll 3 is clamped, the plugging ring 209 is clamped with the high-speed steel roll 3, that is, the protruding blocks are clamped with the corresponding grooves. At this time, controlling the high-speed steel roll 3 will move synchronously with the plugging ring 209.
[0030] Furthermore, an L-shaped limiting plate 210 is fixedly arranged on one side of the first clamping plate 203 close to the plugging ring 209.

[0031] The operation process of this embodiment is as follows: in the initial state, the clamping assembly 2 is above the quenching box 1, the first clamping plate 203 and the second clamping plate 204 are farthest apart, and the high-speed steel roller 3 is placed in the limit groove 202, and then the first motor 206 is driven to drive the bidirectional threaded rod 207 to rotate. At this time, the first clamping plate 203 and the second clamping plate 204 move in the direction of approaching each other until the first clamping plate 203 and the second clamping plate 204 are in contact with each other. At this time, the high-speed steel roller 3 is clamped, and then the hydraulic cylinder 101 is controlled to drive the support plate 201 downward, and the high-speed steel roller 3 moves downward to drive the first clamping plate 203 to move downward, and the second clamping plate 204 moves downward synchronously until the entire clamping assembly 2 and the high-speed steel roller 3 are completely moved into the quenching box 1, and then the high-speed steel roller 3 is heated by the quenching box 1. In this process, the second motor 211 is controlled to drive the first connecting plate to rotate, and the plug-in ring 209 rotates to drive the high-speed steel roller 3 to rotate, so that the high-speed steel roller 3 is heated during the heating process. The rotation occurs in the middle so that the high-speed steel roller 3 is heated more evenly. When the high-speed steel roller 3 is heated, the hydraulic cylinder 101 is controlled to drive the support plate 201 to move upward, and the high-speed steel roller 3 moves upward to drive the first clamping plate 203 to move upward, and the second clamping plate 204 moves upward synchronously until the entire clamping assembly 2 and the high-speed steel roller 3 are completely moved to the top of the quenching box 1, and then the power drive assembly 4 drives the high-speed steel roller 3 to move to the top of the cooling box 501, and the cooling assembly 5 is used to cool the heated high-speed steel roller. When the cooling is completed, the power drive assembly 4 drives the high-speed steel roller 3 to move to the top of the quenching box 1 again, and then the first motor 206 is controlled to reverse and drive the first motor 206 to drive the bidirectional threaded rod 207 to rotate in the opposite direction. At this time, the first clamping plate 203 and the second clamping plate 204 move away from each other until the high-speed steel roller 3 is released from the clamp. At this time, the high-speed steel roller 3 can be moved to the next process and replaced with the next high-speed steel roller 3 that needs quenching.
[0032] Specific embodiment 2, on the basis of specific embodiment 1, the power drive assembly 4 also includes a supporting plate 403, a driving gear, the supporting plate 403 is fixedly connected to the top of the cooling box 501, a third motor 406 is installed on one side of the supporting plate 403, a driving gear is fixedly provided on the output end of the third motor 406, the driving gear is meshed with the driving rack 402, an L-shaped sliding plate 404 is slidingly provided on one side of the cooling box 501, and the L-shaped sliding plate 404 is connected to the L-shaped movable plate 401 by an elastic reset member 405.
[0033] Specifically, the cooling assembly 5 also includes a storage box 502, which is fixedly connected to the cooling box 501, and the storage box 502 is fixedly connected to the quenching box 1 through a fixed plate 6. A water pump 503 is installed on the top of the storage box 502, and the water inlet pipe of the water pump 503 is connected to the storage box 502, and the water outlet end of the water pump 503 is connected to the cooling box 501.
[0034] Furthermore, the interior of the cooling box 501 is divided into a spray chamber 504 and a return chamber 505 (the coolant in the storage tank 502 can be transported into the spray chamber 504 through the water pump 503). A water spraying plate 506 is arranged inside the spray chamber 504, and a number of spray nozzles are installed on the top of the water spraying plate 506. The return chamber 505 is connected to the interior of the storage tank 502 through a return pipe, and a one-way valve is installed inside the return pipe. The spray nozzles cool the high-speed steel roll 3. At this time, the coolant that drops after spraying can enter the return chamber 505, and the one-way valve is controlled to open so that the coolant in the return chamber 505 is transported back into the storage tank 502 again.
[0035] The operation process of this embodiment is as follows: When the high-speed steel roll 3 is heated and returns above the quenching tank 1 again, control the electromagnet to be energized and magnetized. Under the magnetic attraction, the L-shaped moving plate 401 slides along the top of the cooling box 501 and is clamped and matched with the card slot 213. Subsequently, control the third motor 406 to drive the driving gear to rotate, the driving rack 402 moves to drive the L-shaped moving plate 401 to move, so that the second connecting plate 212 moves to drive the second clamping plate 204 to move, and the first clamping plate 203 moves synchronously to drive the high-speed steel roll 3 to move. The positioning plate 205, the first motor 206, the bidirectional threaded rod 207, the insertion ring 209, the L-shaped limiting plate 210, and the second motor 211 move synchronously until the high-speed steel roll 3 moves above the spray chamber 504. Subsequently, control the spray nozzles to spray the coolant. During this process, the second motor 211 drives the high-speed steel roll 3 to rotate selflessly so that the high-speed steel roll 3 is cooled evenly. When the cooling is completed, control the high-speed steel roll 3 to return to the initial state. At this time, the high-speed steel roll 3 can be released from the clamping and transferred to the next process.
