Technical Field

[0001] This invention relates to the field of bearing steel processing technology, and in particular to an intelligent temperature-controlled bearing steel heat treatment system and process. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] For example, a patent entitled "A Heat Treatment Device for Bearing Steel" (patent application number: CN202223576808.3) discloses a heat treatment device for bearing steel. Through the setting of a stirring component, cold water is injected into the treatment tank during use, and then the bearing steel is placed into the tank. After connecting an external power source to power the servo motor, it drives the transmission rod to rotate, which in turn drives the stirring rod to rotate, stirring the bearing steel in the treatment tank. This achieves the effect of ensuring sufficient and rapid contact between the bearing steel and the cold water, allowing the bearing steel to cool quickly and improving work efficiency. However, when the bearing steel is removed, because the floating impurities generated during the quenching process are not treated, these impurities adhere to the bearing steel, affecting its subsequent use. Therefore, the efficiency needs to be improved.

[0004] Therefore, it is necessary to propose an intelligent temperature-controlled heat treatment system and process for bearing steel to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent temperature-controlled heat treatment system and process for bearing steel, in order to solve the problem that when the device removes bearing steel, the floating impurities generated during the quenching process are not treated, and the impurities adhere to the bearing steel, affecting its subsequent use and thus requiring improvement in efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent temperature-controlled bearing steel heat treatment system, comprising a box body with a partition slidably disposed inside, the partition dividing the interior of the box body into a processing chamber and an air chamber, wherein the processing chamber is located above the air chamber;

[0007] The interior of the processing chamber is equipped with a processing basket for placing bearing steel;

A lower hole is provided on the side wall of the housing, and the lower hole communicates with the air chamber. The upper hole and the lower hole are connected by an air pipe.

[0012] Preferably, the air pipe is equipped with a filtration and purification device, which is fixedly connected to the outer wall of the housing.

[0013] Preferably, a first one-way valve is fixedly installed inside the lower hole, an exhaust hole is opened at the bottom of the box, the exhaust hole is connected to the air chamber, and a second one-way valve is fixedly installed inside the exhaust hole.

[0014] Preferably, a second inner groove is provided at the top of the upper hole, a second electric push rod is fixedly connected inside the second inner groove, a second partition is fixedly connected to the telescopic end of the second electric push rod, and the second partition cooperates with the upper hole.

[0015] Preferably, a rotating shaft is rotatably connected to the partition, a bracket is fixedly connected to the top of the rotating shaft, a support rod is fixedly connected to the bracket, a support ring is fixedly connected to the top of the support rod, the processing basket is inserted into the support ring, a motor is fixedly connected to the bottom of the partition, and the rotating shaft is fixedly connected to the drive shaft of the motor.

[0017] This invention also discloses an intelligent temperature-controlled heat treatment process for bearing steel, applied to the aforementioned intelligent temperature-controlled heat treatment system for bearing steel, and further includes the following operating steps:

[0031] This invention provides, for example Figures 1-5The intelligent temperature-controlled bearing steel heat treatment system shown includes a box 1 with a partition 2 slidably arranged inside. The partition 2 divides the interior of the box 1 into a treatment chamber 10 and an air chamber 11, wherein the treatment chamber 10 is located above the air chamber 11 and the interior of the treatment chamber 10 is filled with cooling water.

[0032] Reference Figure 1 As shown, support columns 20 are fixedly installed at the four corners of the bottom of the box 1 to support the box 1.

[0033] In practical use, a sealing ring is provided on the outer wall of the partition 2 to improve the sealing between the partition 2 and the inner wall of the box 1, while reducing the wear of the partition 2 sliding up and down.

[0034] In addition, a temperature sensor 31 and a cooling device are fixedly installed on the top of the partition 2. The cooling device includes structures such as semiconductor cooling chips, and is used to cool the cooling water inside the processing chamber 10. The temperature sensor 31 and the cooling device work together.

[0035] Specifically, a controller can be set to connect between the refrigeration equipment and the temperature sensor 31. When the temperature sensor 31 detects that the temperature exceeds the set threshold, it transmits this information to the controller, which then controls the refrigeration equipment to start. The controller and its control principle are common existing technologies and will not be described in detail here. The temperature sensor 31 and the refrigeration equipment work together to achieve intelligent temperature control.

[0036] A power supply device can also be installed at the bottom of the partition 2 to power the temperature sensor 31, etc. The power supply device includes a battery and other structures.

[0037] Reference Figure 2 As shown, a rotating shaft 3 is rotatably connected to the partition 2. A bracket 4 is fixedly connected to the top of the rotating shaft 3. Multiple brackets 4 are provided, and support rods 5 are fixedly connected to the brackets 4. A support ring 6 is fixedly connected to the top of the support rod 5. A processing basket 7 is inserted into the support ring 6. A motor 9 is fixedly connected to the bottom of the partition 2, and the rotating shaft 3 is fixedly connected to the drive shaft of the motor 9. When the bearing steel is placed inside the processing basket 7, the motor 9 drives the bracket 4 to rotate through the rotating shaft 3. The bracket 4, using the support rods 5 and the support ring 6, drives the processing basket 7 to rotate around the axis of the rotating shaft 3, thereby achieving the effect of ensuring full and rapid contact between the bearing steel and the cooling water, rapid cooling, and improved working efficiency.

[0038] Furthermore, the processing basket 7 is provided with multiple through slots 8, which make the processing basket 7 hollow, so as to facilitate full and rapid contact between the bearing steel and the cooling water.

[0039] The processing basket 7 is fixed inside the support ring 6 by a plug-in method. After cooling, the bearing steel can be removed using the processing basket 7.

[0040] Reference Figure 2 As shown, an electric cylinder 19 is fixedly connected to the bottom of the housing 1, and a partition 2 is fixedly connected to the telescopic end of the electric cylinder 19. When the telescopic end of the electric cylinder 19 extends, it drives the partition 2 to slide upward inside the housing 1. When the telescopic end of the electric cylinder 19 retracts, it drives the partition 2 to slide downward inside the housing 1. The partition 2 slides up and down inside the housing 1, which drives the processing basket 7 and other structures to move up and down synchronously. This allows the processing basket 7 to move up and down while rotating around the axis of the rotating shaft 3, further improving the cooling efficiency.

[0041] Considering that bearing steel will produce floating impurities during quenching and cooling, and that these impurities are at the water surface, if the bearing steel is taken out directly, the impurities will easily adhere to the bearing steel, affecting its subsequent use. Therefore, a sliding channel 12 is provided on the side wall of the housing 1. The sliding channel 12 is connected to the processing chamber 10. A separation plate 13 is slidably arranged inside the sliding channel 12. The upper surface of the bottom of the separation plate 13 is inclined, and the end located outside the processing chamber 10 is inclined downward. The end located outside the processing chamber 10 is connected to a connecting pipe 14.

[0042] The top of the sliding channel 12 is provided with a first inner groove 15. A first electric push rod 16 is fixedly connected to the inner wall of the first inner groove 15. A first partition 17 is fixedly connected to the telescopic end of the first electric push rod 16. The first partition 17 cooperates with the sliding channel 12.

[0043] During the cooling phase, the cooling water level is lower than the sliding channel 12, and the extension end of the first electric push rod 16 is extended, causing the first partition 17 to move downwards and close the sliding channel 12. The separation disc 13 adheres to the side wall of the first partition 17. When it is necessary to remove the bearing steel, the extension end of the electric cylinder 19 is extended, causing the partition 2 to slide upwards inside the housing 1, so that the cooling water level is higher than the sliding channel 12. The extension end of the first electric push rod 16 is then retracted, and the first partition 17 is retracted into the interior of the first inner tank 15. The operator quickly controls the separation disc 13 to move towards the housing. The internal sliding of body 1 and separation plate 13 abut against the inner wall of body 1. Since the upper surface of the bottom of separation plate 13 is inclined and the end located outside the processing chamber 10 is inclined downward, the cooling water at the liquid surface is discharged from separation plate 13 and connecting pipe 14, and at the same time, the impurities at the liquid surface are discharged. After the cooling water at the liquid surface is completely discharged, the extension end of the electric cylinder 19 is retracted, which drives the partition plate 2 to slide downward inside the body 1, and the cooling water drops. Then, the separation plate 13 is controlled to slide towards the outside of the body 1, so that when the bearing steel is taken out, no impurities will adhere to the bearing steel.

[0044] This invention, by setting up structures such as partition 2, processing basket 7 and separation plate 13, causes the bearing steel to rotate around the axis of rotating shaft 3 and move up and down, ensuring rapid cooling and separating and discharging impurities at the liquid surface. This prevents impurities from adhering to the bearing steel when it is taken out, thus improving work efficiency.

[0045] Furthermore, the up-and-down sliding of the baffle 2 can control the liquid level and also push and scrape the impurities remaining on the inner wall of the lower half of the tank 1 upwards, making it easier for operators to clean the inside of the tank 1.

[0046] Reference Figure 4 As shown, a support plate 18 is fixedly connected to the outer wall of the housing 1, and the separation plate 13 is attached to the top of the support plate 18. The support plate 18 is set to support the separation plate 13 and ensure the stability of the sliding of the separation plate 13.

[0047] Considering that waste gas will be generated during the quenching and cooling process, an upper hole 30 is provided on the side wall of the housing 1 to treat the waste gas. The upper hole 30 is located below the separation plate 13 and is connected to the processing chamber 10. A lower hole 23 is provided on the side wall of the housing 1 and is connected to the gas chamber 11. The upper hole 30 and the lower hole 23 are connected by a gas pipe 21. A filtration and purification device 22 is installed on the gas pipe 21. The filtration and purification device 22 is fixedly connected to the outer wall of the housing 1. The filtration and purification device 22 includes a filter screen, activated carbon plate and other structures, which can filter and purify the waste gas. The operator can also regularly inspect and replace the filtration and purification device 22.

[0048] A first one-way valve 24 is fixedly installed inside the lower hole 23. The first one-way valve 24 allows the gas inside the air pipe 21 to enter the air chamber 11 through the lower hole 23 without flowing in the opposite direction. An exhaust hole 25 is opened at the bottom of the box body 1. The exhaust hole 25 is connected to the air chamber 11. A second one-way valve 26 is fixedly installed inside the exhaust hole 25. The first one-way valve 24 allows the gas inside the air chamber 11 to be discharged through the exhaust hole 25 without flowing in the opposite direction.

[0049] In actual use, when the partition 2 slides upward inside the housing 1, it will draw the exhaust gas inside the treatment chamber 10 through the air pipe 21 and the upper hole 30, and the exhaust gas will enter the filter and purification equipment 22 for filtration and purification. When the partition 2 slides downward inside the housing 1, the gas inside the air chamber 11 will be discharged through the exhaust hole 25, thus achieving the effect of exhaust gas treatment.

[0050] During this process, the partition 2 slides upward inside the housing 1, and the level of the cooling water will not exceed the bottom of the upper hole 30, so that the cooling water will not enter the interior of the upper hole 30. In addition, the separation plate 13 closes the top of the housing 1 to ensure the suction efficiency.

[0051] A second inner groove 27 is formed at the top of the upper hole 30. A second electric push rod 28 is fixedly connected inside the second inner groove 27. A second partition 29 is fixedly connected to the telescopic end of the second electric push rod 28, and the second partition 29 cooperates with the upper hole 30. When the telescopic end of the second electric push rod 28 is extended, it will drive the second partition 29 to move downward, closing the upper hole 30. During cooling treatment, the upper hole 30 is closed by the cooperation of the second electric push rod 28 and the second partition 29, while the upper hole 30 is open when treating exhaust gas.

[0052] This invention also discloses an intelligent temperature-controlled heat treatment process for bearing steel, applied to the aforementioned intelligent temperature-controlled heat treatment system for bearing steel, and further includes the following operating steps:

[0053] S1. Place the bearing steel into the processing basket 7 to make the bearing steel come into full and rapid contact with the cooling water;

[0054] S2. Cooling water at the liquid surface is discharged through the separator 13 and connecting pipe 14, while impurities at the liquid surface are also discharged.

[0055] S3. The exhaust gas is treated by sliding the partition 2 up and down inside the box 1.
