Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, specifically to a heat treatment device for bearing rings. Background Technology

[0002] A bearing ring heat treatment device is a specialized piece of equipment used to heat treat bearing rings. Heat treatment refers to a metal hot working process in which materials are heated, held at a certain temperature, and cooled in a solid state to obtain the desired microstructure and properties. The main purpose of the bearing ring heat treatment device is to improve the hardness, wear resistance, and fatigue strength of the bearing rings while maintaining high toughness in their core.

[0003] Existing bearing ring heat treatment devices are widely used, but the bearings are usually stationary during heat treatment, which prevents them from fully contacting the heat treatment liquid. This results in a slow heat treatment rate and may lead to uneven heat treatment of the bearing rings. Furthermore, existing bearing rings are not dehydrated after heat treatment, and prolonged liquid adhesion to the bearing rings can easily lead to a decrease in bearing ring quality. Therefore, a bearing ring heat treatment device is proposed to address the above problems. Utility Model Content

The inner diameters of the positioning hole 9 and the insertion hole 157 are the same, and the inner diameter of the positioning hole 9 is larger than the outer diameter of the output shaft of the electric push rod 11. Part of the fixing block 156 is inserted into the inner side of the fixing frame 8 and the through groove 12, and part of the positioning groove 155 is engaged with the positioning ring 13.

[0027] Workflow: Before use, power on the equipment and add an appropriate amount of heat treatment liquid to the inside of the heat treatment box 2 at the top of the base plate 1. When heat treatment of the bearing ring 154 is required, first place the bearing ring 154 outside the connecting rod 153, then start the telescopic rod 3 and the electric slide rail 4. The output shaft of the telescopic rod 3 extends and drives the electric slide rail 4 and its connecting components to move upward. The electric slider 5 slides inside the electric slide rail 4 until the fixing frame 8 below the connecting plate 6 is vertically aligned with a set of fixing blocks 156. Adjust the telescopic rod 3 to lower its output shaft until the fixing blocks 156 are inserted into the through groove 12 on the disc 10 and the inside of the fixing frame 8. At this time, the positioning ring 13 and the positioning groove 1 on the connecting rod 153 are aligned. 55 engages, then the electric push rod 11 is activated. The output shaft of the electric push rod 11 extends and inserts into the positioning hole 9 and the insertion hole 157, thereby positioning the support rod 152. Next, the telescopic rod 3 and the electric slide rail 4 are adjusted. The output shaft of the telescopic rod 3 extends, driving the electric slide rail 4 and its connecting components to move upward. At this time, the engaging rod 151 disengages from the storage cylinder 14, and the electric slider 5 slides inside the electric slide rail 4 until the storage component 15 below the connecting plate 6 moves above the heat treatment chamber 2. The heat treatment chamber 2 and the rotating motor 7 are activated, and the telescopic rod 3 is adjusted to move the storage component 15 inside the heat treatment chamber 2. The output shaft of the rotating motor 7 drives the storage component 15 to rotate, thereby causing multiple bearings to... The bearing ring 154 can be uniformly heat-treated, improving heat treatment efficiency. After the bearing ring 154 is heat-treated, the rotating motor 7 is turned off, and the telescopic rod 3 and the electric slide rail 4 are adjusted. The output shaft of the telescopic rod 3 extends, driving the electric slide rail 4 and its connecting components to move upward. The electric slider 5 slides inside the electric slide rail 4 until the placement component 15 below the connecting plate 6 moves above the cooling box 16. The telescopic rod 3 is adjusted to move the placement component 15 inside the cooling box 16. The fan 19 and the rotating motor 7 are started. At this time, the fan 19 blows outside air into the cooling box 16 through the ventilation slot 21 and the air inlet pipe 22 to dry the bearing ring 154. The output shaft of the rotating motor 7 drives the placement component 154 to move upward. The assembly 15 rotates rapidly, thereby drying the heat treatment liquid carried on the bearing ring 154. The heat treatment liquid passes through the filter plate 17 and enters the bottom of the cooling box 16. After collecting a certain amount of liquid, the drain valve 23 can be opened to remove the liquid for recycling. The filter plate 17 can intercept some impurities. The ventilation pipe set at an angle on one side of the connecting frame 20 can prevent liquid from entering the inside of the air box 18 and causing the fan 19 to short-circuit. After the bearing ring 154 is dried, the telescopic rod 3 and the electric slide rail 4 are adjusted so that the locking rod 151 is inserted into the inside of the storage cylinder 14. The electric push rod 11 is adjusted to retract its output shaft. Finally, the telescopic rod 3 is adjusted to extend its output shaft, and the worker can then remove the processed bearing ring 154.
