Description

Technical Field

[0001] The utility model belongs to the technical field of quenching equipment, and in particular relates to a quenching device for a wheel hub bearing outer ring forging. Background Art

[0002] Quenching is a heat treatment process that increases the hardness and strength of metal by rapidly cooling it (usually in water, oil, or air) after heating it to a certain temperature. The heating process causes changes in the metal's microstructure, and rapid cooling locks in these changes, creating a harder martensitic structure that improves the material's mechanical properties.

[0003] Problems with existing technologies:

[0004] For example, Chinese utility model patent CN218666192U discloses a device for quenching annular forgings with residual heat, which states that: the annular forgings that need to be quenched are suspended and clamped to ensure stability during the subsequent quenching process and avoid falling, which would require subsequent salvage. Moreover, through the setting of the drive assembly, the suspension assembly can be automatically controlled to lose its clamping of the annular forging, further improving the convenience of operation for the staff. However, when the device is in use, when the annular casting is suspended and clamped for quenching, the annular casting and the clamping structure are always in fixed contact. As a result, the contact points of the annular casting cannot fully contact the cooling medium during quenching, resulting in poor quenching and easy generation of stress. At the same time, when the device is in operation, if the workpiece is not removed in time after quenching, it is easy to be cooled again. Utility Model Content

[0005] The purpose of the utility model is to provide a wheel hub bearing outer ring forging quenching device, which can realize the meshing connection between the magnetic gear and the quenching rack during quenching on the quenching conveyor rack, so that the casting to be quenched and the clamping sliding rod can be transmitted to each other. At the same time, when the quenching on the quenching conveyor rack is completed, the quenched forgings can be automatically collected through the design of the recovery component.

[0006] The technical solutions adopted by this utility model are as follows:

[0007] A wheel hub bearing outer ring forging quenching device comprises: a quenching pool, a limit assembly is provided inside the quenching pool, a magnetic rod is provided outside the quenching pool, and a recovery assembly is provided at one end of the quenching pool;

[0008] The limiting assembly includes a quenching conveyor frame, the outer side of the quenching conveyor frame is connected to a conveyor belt, the lower position of the quenching conveyor frame is fixedly connected to a quenching rack, and the outer side of the conveyor belt is provided with a clamping assembly;

[0009] The clamping assembly includes a buckle frame, one side of the buckle frame is fixedly connected to the conveyor belt, and the other side of the buckle frame is provided with two grooves, and a clamping sliding rod is transversely arranged inside the two grooves, and a clamping cap is fixedly connected to the outer side of the clamping sliding rod located in one of the grooves, and a clamping spring is fixedly connected between the clamping cap and the inner wall of the groove. A magnetic gear is provided at one end of the buckle frame, and the clamping sliding rod extends to the outer side of the buckle frame and is fixedly connected to the magnetic gear. The outer side of the clamping sliding rod located in the other groove is sleeved with a casting to be quenched;

[0010] The recovery component includes a recovery shell, the interior of the recovery shell is slidably connected to an elastic telescopic opening, the lower end of the elastic telescopic opening is set as an arc surface, and a recovery spring is fixedly connected between the elastic telescopic opening and the recovery shell.

[0011] There are multiple clamping assemblies, and the multiple clamping assemblies are arranged in an array on the outer surface of the conveyor belt.

[0012] When the clamping assembly approaches the magnetic rod during the transmission process, the magnetic gear is magnetically attracted by the magnetic rod.

[0013] When the clamping assembly quenches the casting to be quenched during the transmission process, the magnetic gear is meshed and connected with the quenching rack.

[0014] During the transmission process of the clamping assembly, when the magnetic gear is magnetically attracted by the magnetic rod, the casting to be quenched falls into the elastic expansion opening under the action of gravity.

[0015] The technical effects achieved by this utility model are:

[0016] According to the utility model, when the quenching conveyor rack is quenched, the magnetic gear is engaged with the quenching rack, and the clamping sliding rod rotates continuously during the continuous movement of the clamping assembly. The quenching conveyor rack contacts the clamping sliding rod. Under the influence of the clamping sliding rod, the inner side of the quenching conveyor rack is transmitted to the clamping sliding rod, so that the contact point between the casting to be quenched and the clamping sliding rod is constantly changing, so that the quenching conveyor rack is quenched evenly, and the problem of stress concentration at the contact point is effectively avoided.

[0017] The utility model can automatically collect the quenched forgings through the design of the recovery component when the quenching of the casting to be quenched is completed, effectively preventing the casting to be quenched from continuing to be quenched for the second time under the action of the clamping component.

DETAILED DESCRIPTION

[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0027] like Figure 1 - Figure 6 As shown, a wheel hub bearing outer ring forging quenching device includes: a quenching pool 1, a limit assembly is provided inside the quenching pool 1, a magnetic rod 6 is provided outside the quenching pool 1, and a recovery assembly 2 is provided at one end of the quenching pool 1;

[0028] The limiting assembly includes a quenching conveyor frame 7, the outer side of the quenching conveyor frame 7 is connected to a conveyor belt 5 for transmission, the lower position of the quenching conveyor frame 7 is fixedly connected to a quenching rack 4, and a clamping assembly 3 is provided on the outer side of the conveyor belt 5.

[0029] Among them, the quenching pool 1 is filled with quenching liquid. The staff uses equipment to place the forged casting 8 to be quenched and controlled at the quenching temperature at the position of the clamping component 3 at the end of the quenching pool 1 away from the recovery component 2, and clamps it under the action of the magnetic rod 6. The clamping component 3 carries the casting 8 to be quenched into the quenching pool 1 under the drive of the conveyor belt 5 so that the casting 8 to be quenched is fully in contact with the quenching liquid. During this period, the quenching rack 4 is connected to the clamping component 3 through meshing, so that the casting 8 to be quenched rotates continuously, so that the inner surface is in uniform contact with the quenching liquid, and then reaches the position of the recovery component 2. Under the action of the magnetic rod 6, the clamping of the clamping component 3 is opened, so that the casting 8 to be quenched falls into the recovery component 2 for collection.

[0030] Refer to the attached Figure 1 - Figure 4 The clamping assembly 3 includes a buckle frame 301, one side of the buckle frame 301 is fixedly connected to the conveyor belt 5, and the other side of the buckle frame 301 is provided with two grooves. A clamping sliding rod 305 is arranged horizontally inside the two grooves. The outer side of the clamping sliding rod 305 located in one of the grooves is fixedly connected to a clamping cap 303, and a clamping spring 304 is fixedly connected between the clamping cap 303 and the inner wall of the groove. A magnetic gear 302 is provided at one end of the buckle frame 301, and the clamping sliding rod 305 extends to the buckle The outer side of the closing frame 301 is fixedly connected to the magnetic gear 302, and the clamping sliding rod 305 is located on the outer side of another groove inside which the casting 8 to be quenched is sleeved; there are multiple clamping assemblies 3, and multiple clamping assemblies 3 are arranged in an array on the outer surface of the conveyor belt 5; when the clamping assembly 3 approaches the magnetic rod 6 during the transmission process, the magnetic gear 302 is magnetically attracted by the magnetic rod 6; when the clamping assembly 3 quenches the casting 8 to be quenched during the transmission process, the magnetic gear 302 is meshed and connected with the quenching rack 4.

[0031] According to the above structure, when the casting 8 to be quenched is first mounted on the clamping assembly 3, the magnetic gear 302 is magnetically attracted by the magnetic rod 6, so that the magnetic gear 302 slides horizontally on the snap-fit ​​frame 301. At this time, the clamping cap 303 compresses the clamping spring 304 and moves toward the magnetic rod 6. At this time, the clamping sliding rod 305 in the other groove is pulled out. At this time, the casting 8 to be quenched is placed into the groove. When the clamping assembly 3 continues to move away from the magnetic rod 6, the clamping cap 303 returns to its original position under the action of the clamping spring 304. At this time, the clamping sliding rod 305 is inserted into the interior of the casting 8 to be quenched to limit it.

[0032] When the casting to be quenched 8 is quenched, the clamping assembly 3 moves horizontally under the action of the conveyor belt 5. At this time, the casting to be quenched 8 and the clamping sliding rod 305 are relatively stationary. When the magnetic gear 302 contacts and engages with the quenching rack 4, the magnetic gear 302 rotates under the reaction force of the quenching rack 4, causing the clamping sliding rod 305 to rotate synchronously. At this time, the clamping sliding rod 305 is transmission-connected to the casting to be quenched 8. The casting to be quenched 8 rotates along the clamping sliding rod 305, so that the contact point between the casting to be quenched 8 and the clamping sliding rod 305 keeps changing, so that the inner surface of the casting to be quenched 8 is evenly contacted with the quenching liquid, effectively preventing the occurrence of stress concentration.

[0033] Refer to the attached Figure 5 - Figure 6 The recovery component 2 includes a recovery shell 201, and the internal sliding connection of the recovery shell 201 is an elastic telescopic opening 202, the lower end of the elastic telescopic opening 202 is set to an arc surface, and a recovery spring 203 is fixedly connected between the elastic telescopic opening 202 and the recovery shell 201; during the transmission process of the clamping component 3, when the magnetic gear 302 is magnetically attracted by the magnetic rod 6, the quenching conveying rack 7 falls into the elastic telescopic opening 202 under the action of gravity.

[0034] According to the above structure, during the movement of the clamping component 3, it contacts the arc surface of the elastic telescopic opening 202. At this time, the recovery spring 203 is compressed, allowing the clamping component 3 to pass smoothly. Then the magnetic gear 302 moves its position under the action of the magnetic rod 6, and the clamping sliding rod 305 pulls out the casting to be quenched 8, causing the casting to be quenched 8 to fall from the clamping component 3. At this time, the clamping component 3 is away from the elastic telescopic opening 202. The elastic telescopic opening 202 returns to its original position under the action of the recovery spring 203 and just catches the fallen casting to be quenched 8. It is collected by the storage box 204 placed under the recovery shell 201 to prevent it from being quenched again while also reducing the workload of the staff.

[0035] The working principle of the present utility model is as follows: the quenching pool 1 is filled with quenching liquid, and the staff uses the equipment to place the forged casting 8 to be quenched and controlled at the quenching temperature at the position of the clamping component 3 at one end of the quenching pool 1 away from the recovery component 2, and clamps it under the action of the magnetic rod 6. The clamping component 3 carries the casting 8 to be quenched under the drive of the conveyor belt 5 and enters the interior of the quenching pool 1 so that the casting 8 to be quenched is fully in contact with the quenching liquid. During this period, the quenching rack 4 is engaged with the clamping component 3, so that the casting 8 to be quenched rotates continuously, so that the inner surface is in uniform contact with the quenching liquid, and then reaches the position of the recovery component 2. Under the action of the magnetic rod 6, the clamping of the clamping component 3 is opened, so that the casting 8 to be quenched falls into the interior of the recovery component 2 for collection.

[0036] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
