Bearing forging annealing spheroidizing furnace

Abstract

This utility model discloses a bearing forging annealing and spheroidizing furnace, belonging to the field of bearing forging processing technology. It includes a furnace body with an inner cavity. A retaining ring is fixedly installed in the inner cavity, and a mounting plate is provided within the inner cavity. The mounting plate has a retaining groove, and the mounting plate is engaged with the retaining ring through the retaining groove. The mounting plate has several sliding grooves, with two sliding grooves forming a group. A sliding rod is slidably installed within each sliding groove, and a positioning block is connected to the end of the sliding rod. This bearing forging annealing and spheroidizing furnace uses a rotating shaft to drive a rotating block and a connecting rod to rotate. When the connecting rod rotates, the top block contacts the arc block, thereby compressing the arc block. The compressed arc block causes a moving disk to move upwards, which in turn causes the sliding rod to move within the sliding groove. The movement of the sliding rod synchronously moves the fixed bearing forging, thus uniformly annealing the surface of the bearing forging, improving quality and reducing operating costs.

Description

Technical Field

[0001] This utility model belongs to the field of bearing forging processing technology, specifically a bearing forging annealing and spheroidizing furnace. Background Technology

[0002] Bearing forgings are the blanks used to manufacture bearings. They are formed by pressing and shaping metal blanks through a forging process. An essential processing step for bearing forgings is annealing. Annealing is a heat treatment process in which the forging is heated to a certain temperature, held at that temperature, and then slowly cooled. The purpose is to eliminate forging stress, refine the grain, reduce hardness, improve its machinability and plasticity, prepare it for subsequent quenching and other processes, and stabilize its dimensions to reduce deformation during subsequent processing.

[0003] Currently, in existing bearing forging annealing and spheroidizing furnaces, the bearing forgings inside are usually stationary during operation. Over time, this leads to uneven surface temperature of the bearing forgings, resulting in reduced quality and increased operating costs. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a bearing forging annealing and spheroidizing furnace, which solves the problem that in the current bearing forging annealing and spheroidizing furnace, the bearing forgings inside are usually fixed during operation, which leads to uneven surface temperature of the bearing forgings over time, resulting in reduced quality and increased operating costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing forging annealing and spheroidizing furnace, comprising a furnace body, an inner cavity formed in the furnace body, a retaining ring fixedly installed in the inner cavity, a mounting plate provided in the inner cavity, a retaining groove formed in the mounting plate, the mounting plate being engaged with the retaining ring through the retaining groove, a plurality of sliding grooves formed in the mounting plate, two sliding grooves forming a group, a sliding rod slidably installed in the sliding groove, a positioning block connected to the end of the sliding rod, a movable disk connected to the bottom of the sliding rod, a plurality of arc blocks fixedly installed at the bottom of the movable disk, a rotating block installed in the inner cavity through a bearing, a plurality of connecting rods fixedly installed on the rotating block, a top block fixedly installed on the connecting rod, and a protective box fixedly installed at the bottom of the furnace body.

[0006] As a further embodiment of this utility model: a motor is installed inside the protective box, and a rotating shaft is connected to the output shaft of the motor. The rotating shaft passes through the furnace body and is connected to the rotating block.

[0007] As a further embodiment of this utility model: a buffer spring is sleeved on the slide rod, and two fixing grooves are formed on the positioning block.

[0008] As a further embodiment of this utility model: a spring rod is installed in the fixing groove, and a positioning arc plate is connected to the end of the spring rod.

[0009] As a further embodiment of this utility model: a sealing cover is installed on the furnace body, and a handle is fixedly installed on the sealing cover.

[0010] As a further embodiment of this utility model: several support legs are fixedly installed at the bottom of the furnace body, and several heating rings are installed in the inner cavity.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This bearing forging annealing and spheroidizing furnace, equipped with a sealing cover, inner cavity, motor, and arc block, allows for efficient operation. During operation, the operator first removes the sealing cover using the handle, places the bearing forging to be processed on the mounting plate and secures it, then replaces the sealing cover. The heating ring is then activated to anneal the bearing forging in the inner cavity. During processing, the motor installed inside the protective box is turned on. The motor's output shaft drives the rotating shaft, which in turn drives the rotating block and connecting rod. As the connecting rod rotates, the top block contacts the arc block, thus compressing it. This compression causes the moving plate to move upwards, which in turn moves the sliding rod within the sliding groove. The sliding rod's movement synchronously moves the secured bearing forging, resulting in uniform annealing of the bearing forging surface, improving quality and reducing operating costs.

[0013] 2. This bearing forging annealing and spheroidizing furnace, by setting up a positioning block, a positioning arc plate, an inner cavity, and a spring rod, allows the forging to be annealed quickly and easily. During operation, after the operator removes the sealing cover, aligns the inner ring of the bearing forging with the positioning block and moves the forging downwards. The inner ring of the forging presses against the positioning arc plate, causing it to move under pressure. This movement compresses the spring rod installed in the fixing groove, and the elastic force generated by the spring rod is transmitted to the positioning arc plate, making it adhere tightly to the inner ring of the bearing forging. This facilitates the subsequent annealing process. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-5 As shown, this utility model provides a technical solution: a bearing forging annealing and spheroidizing furnace, including a furnace body 1, a sealing cover 2 installed on the furnace body 1, and a handle 3 fixedly installed on the sealing cover 2. Because the sealing cover 2 is installed, the high-temperature gas inside the furnace is prevented from leaking out and cold air is prevented from entering, the required temperature atmosphere for annealing is maintained, heat loss is reduced, and the quality and efficiency of bearing forging spheroidizing annealing are guaranteed.

[0022] Several support legs 4 are fixedly installed at the bottom of the furnace body 1, and several electric heating rings 6 are installed in the inner cavity 5. Because of the installation of several electric heating rings 6, a uniform and stable heat source can be provided for the annealing of bearing forgings through multiple electric heating rings 6. The distribution of multiple rings ensures uniform temperature in the furnace, promotes spheroidization of metal structure, and ensures annealing quality and forging performance.

[0023] The furnace body 1 has an inner cavity 5, in which a retaining ring 8 is fixedly installed. A mounting plate 7 is located within the inner cavity 5, and a retaining groove 12 is provided on the mounting plate 7. The mounting plate 7 is engaged with the retaining ring 8 via the retaining groove 12. Several sliding grooves 13 are provided on the mounting plate 7, with two sliding grooves 13 forming a group. A sliding rod 22 is slidably installed within the sliding groove 13, and a buffer spring 23 is sleeved on the sliding rod 22. Two fixing grooves 20 are provided on the positioning block 9, and a spring rod 24 is installed within the fixing groove 20. The end of the spring rod 24 is connected to a positioning arc plate 21. Due to the installation of the spring rod 24, during the installation of the bearing forging, the inner ring of the bearing forging will press against the positioning arc plate 21. The pressure exerted on the positioning arc plate 21 will cause it to move, compressing the spring rod 24 installed within the fixing groove 20. The elastic force generated by the spring rod 24 will be transmitted to the positioning arc plate 21, causing it to adhere tightly to the inner ring of the bearing forging. This allows for quick fixation of the bearing forging, facilitating subsequent annealing.

[0024] A positioning block 9 is connected to the end of the slide rod 22, and a movable disk 11 is connected to the bottom of the slide rod 22. Several arc blocks 14 are fixedly installed at the bottom of the movable disk 11. A rotating block 17 is installed in the inner cavity 5 through bearings. Several connecting rods 15 are fixedly installed on the rotating block 17, and a top block 16 is fixedly installed on the connecting rods 15. A protective box 10 is fixedly installed at the bottom of the furnace body 1. A motor 19 is installed inside the protective box 10. A rotating shaft 18 is connected to the output shaft of the motor 19. The rotating shaft 18 passes through the furnace body 1 and connects to the rotating block 17. Because a motor is installed... 19. During the annealing process of the bearing forging, the motor 19 is turned on, and the output shaft of the motor 19 drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the rotating block 17 and the connecting rod 15 to rotate. The top block 16 presses the arc block 14. The arc block 14 being pressed will drive the moving disk 11 to move upward. The movement of the moving disk 11 will drive the slide rod 22 to move in the slide groove 13. The movement of the slide rod 22 will drive the fixed bearing forging to move synchronously, thereby uniformly annealing the surface of the bearing forging, improving the quality and reducing the working cost.

[0025] The working principle of this utility model is as follows: During operation, the operator first removes the sealing cover 2 using handle 3, then aligns the inner ring of the bearing forging with the positioning block 9, and moves the bearing forging downwards. During this process, the inner ring of the bearing forging will press against the positioning arc plate 21. The positioning arc plate 21 will move under the pressure of the compression, and the movement of the positioning arc plate 21 will compress the spring rod 24 installed in the fixing groove 20. The elastic force generated by the spring rod 24 will be transmitted to the positioning arc plate 21, making it fit tightly against the inner ring of the bearing forging. After the sealing cover 2 is replaced, the heating ring 6 is activated to heat the inner cavity 5. The bearing forgings are annealed. During the process, the motor 19 installed inside the protective box 10 is opened. The output shaft of the motor 19 drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the rotating block 17 and the connecting rod 15 to rotate. When the connecting rod 15 rotates, the top block 16 will contact the arc block 14, thereby squeezing the arc block 14. The squeezing of the arc block 14 will drive the moving disk 11 to move upward. The movement of the moving disk 11 will drive the slide rod 22 to move in the slide groove 13. The movement of the slide rod 22 will drive the fixed bearing forgings to move synchronously, thereby annealing the surface of the bearing forgings evenly.
