Description

Technical Field

[0001] This utility model relates to the field of bearing production technology, specifically a quenching device for bearing ring production. Background Technology

[0002] Bearing races are the core components of bearings, and the quality of their heat treatment directly determines the bearing's lifespan, wear resistance, and reliability. Quenching is the most critical step in the heat treatment process, and its purpose is to rapidly cool the races heated to the austenitizing temperature to obtain a martensitic structure with high hardness and high wear resistance.

[0003] However, traditional quenching equipment has a slow line changeover time, and each batch of workpieces needs to be moved or temporarily tooled up and down piece by piece, which is a clear bottleneck.

[0004] Secondly, poor adaptability, large parts cannot be inserted, small parts are easy to shake, and temporary binding is necessary. The process is unstable, the cooling is uneven, and the channels are blocked or the gaps are too large, resulting in poor hardness distribution and abnormal structure.

[0005] Finally, the bearing rings have a low loading rate and can only be placed in a single layer or sparsely, which limits production capacity and energy consumption. The rings tumble and move to the side in the cooling medium, causing one side to cool too quickly, which may lead to soft spots or cracks. Summary of the Invention

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

[0021] Example 1: Please see Figures 1-5 A quenching device for producing bearing rings includes a main body 1, a connecting mechanism, and a stacking mechanism. The connecting mechanism includes a connecting frame 2 and a placement frame 3. The connecting frame 2 is mounted on the placement frame 3 and is connected to it. The connecting frame 2 is equipped with a rotating component 4 and a locking block 5. The rotating component 4 is mounted on the connecting frame 2 and is connected to both the connecting frame 2 and the locking block 5. The locking block 5 is slidably connected to both the connecting frame 2 and the placement frame 3. The stacking mechanism includes a first shelf 6 and a second shelf 7. The first shelf 6 and the second shelf 7 are mounted inside the placement frame 3 and are connected to it. Support rods 8 are provided on the first shelf 6 and the second shelf 7. The support rods 8 are distributed in a linear array in the first shelf 6 and the second shelf 7.

[0022] In this embodiment, the connecting mechanism includes a connecting frame 2 and a placement frame 3. In use, the first shelf 6 and the second shelf 7 can be installed into the placement frame 3 first, followed by the connecting frame 2 being installed onto the placement frame 3. At this point, the mating groove 14 on the connecting frame 2 engages with the mating block 13 on the placement frame 3. Then, the positioning rod 20 installed on the connecting frame 2 can be pulled directly, causing the positioning rod 20 to disengage from the positioning hole 21 on the rotating member 4. During this process, the positioning rod 20 directly compresses the spring 22, allowing the connecting frame 2 to rotate. The rotating part 4 on the rotating part 4 is connected to the threaded hole 17 in the locking block 5, so that the locking block 5 is connected to the locking hole 15 in the mating block 13, thus completing the connection between the connecting frame 2 and the placement frame 3. Then the positioning rod 20 can be released, so that the spring 22 directly pushes the positioning rod 20 into the positioning hole 21 of the rotating part 4, thus making the connection between the connecting frame 2 and the placement frame 3 more stable. Moreover, when the locking block 5 slides on the connecting frame 2, the roller 16 slides in the sliding groove 19, making the sliding of the locking block 5 more stable.

[0023] In this embodiment, the stacking mechanism includes a first shelf 6 and a second shelf 7. In use, bearing rings can be placed in the first shelf 6 and the second shelf 7, so that the bearing rings are placed on the support rods 8 of the first shelf 6 and the second shelf 7. Then, the first shelf 6 and the second shelf 7 can be installed into the placement rack 3. The limiting blocks 12 on the first shelf 6 and the second shelf 7 are slidably connected to the limiting grooves 11 on the placement rack 3. Then, with the cooperation of the connecting frame 2, the positions of the first shelf 6 and the second shelf 7 are fixed. Then, the connecting frame 2 can be lifted up and the whole thing can be placed into the body 1 filled with cooling oil for quenching.

[0024] Example 2: In summary, during use, the first shelf 6 and the second shelf 7 can be installed into the storage rack 3 first, and then the connecting frame 2 can be installed onto the storage rack 3. At this time, the mating groove 14 on the connecting frame 2 and the mating block 13 on the storage rack 3 are engaged. Then, the positioning rod 20 installed on the connecting frame 2 can be pulled directly, so that the positioning rod 20 can disengage from the positioning hole 21 on the rotating part 4. During this process, the positioning rod 20 directly compresses the spring 22. Then, the rotating part 4 installed on the connecting frame 2 can be rotated, so that the screw 18 on the rotating part 4 is engaged with the threaded hole 17 in the locking block 5, thereby making the locking block 5 engage with the locking hole 15 in the mating block 13, completing the connection between the connecting frame 2 and the storage rack 3. Then, the positioning rod 20 can be released, so that the spring 22 directly pushes the positioning rod 20 into the rotating part 4. The positioning hole 21 is inserted into the frame, making the connection between the connecting frame 2 and the placement frame 3 more stable. When the locking block 5 slides on the connecting frame 2, the roller 16 slides in the sliding groove 19, making the sliding of the locking block 5 more stable. At this time, the bearing rings can be placed in the first shelf 6 and the second shelf 7, so that the bearing rings are placed on the support rods 8 of the first shelf 6 and the second shelf 7. Then the first shelf 6 and the second shelf 7 can be installed into the placement frame 3. The limiting block 12 on the first shelf 6 and the second shelf 7 is slidably connected to the limiting groove 11 on the placement frame 3. Then, with the cooperation of the connecting frame 2, the positions of the first shelf 6 and the second shelf 7 are fixed. Then the connecting frame 2 can be lifted up and the whole thing can be placed into the body 1 filled with cooling oil for quenching.

[0025] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
