Description

Technical Field

[0001] This utility model belongs to the field of bearing steel quenching technology, and in particular relates to a vacuum quenching device for bearing steel. Background Technology

[0002] Vacuum quenching of bearing steel involves heating the bearing steel uniformly to a suitable quenching temperature using a vacuum heating device in a low-pressure vacuum environment, followed by rapid cooling using a medium such as high-pressure inert gas or vacuum quenching oil. This process effectively avoids the drawbacks of oxidation and decarburization caused by air intervention during traditional quenching, precisely controls thermal stress and structural stress, and significantly reduces workpiece deformation.

[0003] For example, Chinese patent CN222274618U discloses a vacuum quenching device for bearing steel. In this application, a vacuum quenching device for bearing steel includes a base plate. An isolation protection plate is positioned adjacent to the base plate, and a cleaning platform is fixedly connected to the adjacent position of the isolation protection plate. The cleaning platform has a cleaning tank inside, and multiple rectangular mounting plates are fixedly connected to the upper end of the cleaning platform adjacent to the cleaning tank. After the operation is completed, the fixing bolts are removed, and the rectangular mounting plates are placed back into the equipment. The bolts are then re-fixed to the equipment to ensure the stability of the equipment structure. The isolation protection plate isolates the positions of components between devices, preventing interference and facilitating operation. This structure allows workers to quickly remove the bearing steel being cleaned, saving them time.

[0004] The aforementioned patent has the following problems:

[0005] This patented device has several drawbacks in its use. For example, the filter plate requires manual movement, which is cumbersome. Furthermore, the filter plate is secured with small bolts, which are easily lost after removal, adding to the inconvenience. Additionally, the device relies on natural drainage, which is time-consuming and ineffective, and the presence of moisture in the bearing steel can negatively impact the quality after quenching. Therefore, we propose a vacuum quenching device for bearing steel. Utility Model Content

[0006] The purpose of this invention is to provide a vacuum quenching device for bearing steel to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a vacuum quenching device for bearing steel, comprising:

[0008] A base, on the top of which a vacuum quenching chamber is fixedly installed, and a cleaning tank is provided on the top of the base and on one side of the vacuum quenching chamber. A drain basket is slidably installed in the cleaning tank. A movable plate one and a movable plate two are fixedly installed on the top of the drain basket. A dustproof plate is rotatably installed on the movable plate two. A filter screen two is fixedly installed inside the dustproof plate.

[0009] A drive assembly, located within the base, is used to drive the movable plate to move up and down.

[0010] A limiting component, which is located within the movable plate and is used to limit the dustproof plate;

[0011] The groove is formed inside the base and located between the vacuum quenching chamber and the cleaning tank. A filter screen is fixedly installed on the top of the groove. Several air outlets connected to the cleaning tank are opened on one side of the groove. Heating wire, several fan blades, mounting plate and several motors are arranged in the groove from left to right.

[0012] In this technical solution, during use, personnel can release the dustproof plate through the limiting component, and personnel can open the dustproof plate upwards to ensure that when not in use, personnel can cover the cleaning tank through the dustproof plate to prevent dust from entering the cleaning tank, so that the dust in the cleaning tank does not need to be cleaned before the next use, which is more convenient.

[0013] Then, the personnel can place the bearing steel that needs to be quenched into the cleaning tank for pretreatment. After the treatment is completed, the personnel can drive the first moving plate to move upward through the drive component. The upward movement of the first moving plate will drive the drain basket to move upward. The upward movement of the drain basket will drive the second moving plate to move upward. The upward movement of the second moving plate will drive the limit rod to move within the base. The limit rod can maintain the stability of the drain basket when it moves. At the same time, the upward movement of the drain basket will drive the treated bearing steel to move upward until the bearing steel in the drain basket leaves the water surface in the cleaning tank. At this time, the drain basket can drain the water from the bearing steel. It can be automatically raised without the need for manual raising and lowering of the drain basket, and no fixing bolts are needed to fix it, avoiding the situation of the fixing bolts being lost.

[0014] At this point, the drain basket will be located on one side of several air outlets. Then, personnel can start several motors, and the output ends of these motors will drive several fan blades to rotate. The rotation of these fan blades will draw outside air into the groove through the filter screen. At the same time, the filter screen will filter out dust in the air, preventing dust from entering the groove. Simultaneously, the heating wire will be energized, and the air blown out by the fan blades will be heated by the heating wire and then blown into the bearing steel in the drain basket through the air outlets. This will dry the bearing steel in the drain basket, ensuring that it is dried quickly and that the surface of the bearing steel does not contain moisture during quenching, thus avoiding affecting the quality of the bearing steel after quenching.

[0015] In the above technical solution, the driving component further includes:

[0016] A sliding groove is formed inside the base and located on one side of the movable plate. A sliding rod is slidably installed in the sliding groove, and the top end of the sliding rod passes through the top of the sliding groove and is fixed to the movable plate. A threaded rod is rotatably installed in the sliding groove, and the top end of the threaded rod extends into the sliding rod. An installation groove is formed inside the base and below the sliding groove. A motor is fixedly installed in the installation groove, and the output end of the motor passes through the top of the installation groove and is coaxially connected to the threaded rod. A limit rod is fixedly installed at the bottom of the movable plate, and the bottom end of the limit rod extends into the base.

[0017] In this technical solution, starting the motor causes the output shaft to rotate the threaded rod. The rotation of the threaded rod, under the action of the thread, causes the sliding rod to move upwards. This upward movement of the sliding rod causes the first moving plate to move upwards, which in turn causes the drain basket to move upwards. The upward movement of the drain basket then causes the second moving plate to move upwards, which in turn causes the limiting rod to move within the base. The limiting rod maintains the stability of the drain basket during movement. Simultaneously, the upward movement of the drain basket causes the treated bearing steel to move upwards until the bearing steel in the drain basket leaves the water surface in the cleaning tank. At this point, the drain basket can drain the water from the bearing steel, ensuring automatic lifting of the drain basket without manual operation and without the need for fixing bolts, thus avoiding the possibility of lost fixing bolts.

[0018] In the above technical solution, the threaded rod is threadedly connected to the sliding rod, the output shaft of the motor is rotatably connected to the base, and the limiting rod is slidably connected to the base.

[0019] In this technical solution, it is ensured that the rotation of the threaded rod can drive the sliding rod to move, that the output shaft of the motor can rotate normally within the base, and that the limit rod can slide normally within the base.

[0020] In the above technical solution, the limiting component further includes:

[0021] A sliding groove is formed inside a movable plate and located on one side of a dustproof plate. A limiting block is slidably installed inside the sliding groove. One end of the limiting block passes through one side of the sliding groove and extends into the dustproof plate. A spring that is fixed to the inner wall of the sliding groove is fixed to the other end of the limiting block. The top of the limiting block passes through the sliding groove and extends to the outside.

[0022] In this technical solution, pulling the limiting block will cause the limiting block to move, which will compress the spring. When one end of the limiting block moves out of the dustproof plate, the limiting block can release the dustproof plate, and the personnel can open the dustproof plate upwards. This ensures that when not in use, the personnel can cover the cleaning tank through the dustproof plate to prevent dust from entering the cleaning tank. This makes it convenient that the dust in the cleaning tank does not need to be cleaned before the next use.

[0023] In the above technical solution, one end of the limiting block is inserted into the dustproof plate, and one end of the limiting block has an inclined structure.

[0024] In this technical solution, one end of the limiting block can be inserted into the dustproof plate, ensuring that the dustproof plate can squeeze the limiting block to move when closed.

[0025] In the above technical solution, the heating wire is fixedly connected to the inner wall of the groove, the mounting plate is tightly welded to the inner wall of the groove, the fan blade is rotatably connected to the mounting plate, the motor is fixedly connected to the mounting plate, the output ends of the plurality of motors all pass through the mounting plate and are coaxially connected to the plurality of fan blades respectively, and the output shaft of the motor is rotatably connected to the mounting plate.

[0026] In this technical solution, the structure of the heating wire, mounting plate, and motor is ensured to be stable, the fan blades can rotate normally on the mounting plate, and the output shaft of the motor can rotate normally within the mounting plate.

[0027] In the above technical solution, the groove is further located above the drain basket.

[0028] In this technical solution, the structural stability of the groove and the drain basket is ensured.

[0029] The beneficial effects of this utility model are:

[0030] 1. This bearing steel vacuum quenching device, through the setting of a limiting component, and the cooperation of the limiting component, dustproof plate, cleaning tank and filter screen 2, can prevent dust from entering the cleaning tank, so that the dust in the cleaning tank does not need to be cleaned before the next use, which is more convenient.

[0046] Example 1:

[0047] Please see Figure 1 - Figure 6 As shown, this embodiment provides a vacuum quenching device for bearing steel, comprising:

[0048] A base 1 is provided, and a vacuum quenching chamber 2 is fixedly installed on the top of the base 1. A cleaning tank 3 is provided on the top of the base 1 and on one side of the vacuum quenching chamber 2. A drain basket 4 is slidably installed in the cleaning tank 3. A movable plate 1 5 and a movable plate 2 6 are fixedly installed on the top of the drain basket 4. A dustproof plate 23 is rotatably installed on the movable plate 2 6. A filter screen 24 is fixedly installed inside the dustproof plate 23.

[0049] The drive assembly is located inside the base 1 and is used to drive the moving plate 5 to move up and down.

[0050] A limiting component is located within the movable plate 5 and is used to limit the dustproof plate 23.

[0051] The groove 16 is located inside the base 1 and between the vacuum quenching chamber 2 and the cleaning tank 3. A filter screen 17 is fixedly installed on the top of the groove 16. Several air outlets 18 connected to the cleaning tank 3 are provided on one side of the groove 16. A heating wire 21, several fan blades 20, a mounting plate 19 and several motors 22 are arranged in the groove 16 from left to right.

[0052] During use, personnel can release the limit on the dustproof plate 23 through the limiting component, and can open the dustproof plate 23 upwards to ensure that when not in use, personnel can cover the cleaning tank 3 through the dustproof plate 23 to prevent dust from entering the cleaning tank 3, so that the dust in the cleaning tank 3 does not need to be cleaned before the next use, which is more convenient.

[0053] Then, the personnel can place the bearing steel that needs to be quenched into the cleaning tank 3 for pretreatment. After the treatment is completed, the personnel can drive the moving plate 5 to move upward through the drive component. The upward movement of the moving plate 5 will drive the drain basket 4 to move upward. The upward movement of the drain basket 4 will drive the moving plate 6 to move upward. The upward movement of the moving plate 6 will drive the limit rod 7 to move within the base 1. The limit rod 7 can maintain the stability of the drain basket 4 when it moves. At the same time, the upward movement of the drain basket 4 will drive the treated bearing steel to move upward until the bearing steel in the drain basket 4 leaves the water surface in the cleaning tank 3. At this time, the drain basket 4 can drain the water from the bearing steel. It can be ensured that the drain basket 4 can be automatically raised without the need for personnel to manually raise or lower the drain basket 4, and no fixing bolts are needed to fix it, avoiding the situation of the fixing bolts being lost.

[0054] At this time, the drain basket 4 will be located on one side of several air outlets 18. Then, personnel can start several motors 22. The output ends of several motors 22 will drive several fan blades 20 to rotate. The rotation of several fan blades 20 can draw outside air into the groove 16 through the filter screen 17. At the same time, the filter screen 17 can filter dust in the air to prevent dust from entering the groove 16. Simultaneously, the heating wire 21 is energized, and the air blown out by several fan blades 20 will be heated by the heating wire 21 and then blown into the bearing steel in the drain basket 4 through several air outlets 18. At this time, the bearing steel in the drain basket 4 can be dried to ensure that the bearing steel in the drain basket 4 can be dried quickly, so that the surface of the bearing steel does not contain moisture during quenching, thus avoiding affecting the quality of the bearing steel after quenching.

[0055] Example 2:

[0056] This embodiment provides a vacuum quenching device for bearing steel, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a drive component comprising:

[0057] A sliding groove 8 is formed inside the base 1 and located on one side of the moving plate 5. A sliding rod 9 is slidably installed inside the sliding groove 8. The top end of the sliding rod 9 passes through the top of the sliding groove 8 and is fixed to the moving plate 5. A threaded rod 10 is rotatably installed inside the sliding groove 8. The top end of the threaded rod 10 extends into the sliding rod 9. An installation groove 11 is formed inside the base 1 and below the sliding groove 8. A motor 12 is fixedly installed inside the installation groove 11. The output end of the motor 12 passes through the top of the installation groove 11 and is coaxially connected to the threaded rod 10. A limit rod 7 is fixedly installed at the bottom of the moving plate 6. The bottom end of the limit rod 7 extends into the base 1.

[0058] When the motor 12 is started, its output shaft drives the threaded rod 10 to rotate. Under the action of the thread, the rotation of the threaded rod 10 drives the sliding rod 9 to move upward. The upward movement of the sliding rod 9 drives the moving plate 1 5 to move upward. The upward movement of the moving plate 1 5 drives the drain basket 4 to move upward. The upward movement of the drain basket 4 drives the moving plate 2 6 to move upward. The upward movement of the moving plate 2 6 drives the limiting rod 7 to move within the base 1. The limiting rod 7 can maintain the stability of the drain basket 4 during movement. At the same time, the upward movement of the drain basket 4 will drive the treated bearing steel to move upward until the bearing steel in the drain basket 4 leaves the water surface in the cleaning tank 3. At this time, the drain basket 4 can drain the water from the bearing steel, ensuring that the drain basket 4 can be automatically raised without the need for manual raising and lowering, and without the need for fixing bolts, thus avoiding the situation where the fixing bolts are lost.

[0059] Example 3:

[0060] This embodiment provides a vacuum quenching device for bearing steel. In addition to the technical solutions of the above embodiments, it also has the following technical features: the threaded rod 10 is threadedly connected to the sliding rod 9, the output shaft of the motor 12 is rotatably connected to the base 1, and the limiting rod 7 is slidably connected to the base 1.

[0061] Specifically, it ensures that the rotation of the threaded rod 10 can drive the sliding rod 9 to move, ensures that the output shaft of the motor 12 can rotate normally within the base 1, and ensures that the limit rod 7 can slide normally within the base 1.

[0062] Example 4:

[0063] This embodiment provides a vacuum quenching device for bearing steel, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a limiting component:

[0064] The slide 13 is formed inside the movable plate 5 and located on one side of the dustproof plate 23. A limiting block 14 is slidably installed inside the slide 13. One end of the limiting block 14 passes through one side of the slide 13 and extends into the dustproof plate 23. The other end of the limiting block 14 is fixedly installed with a spring 15 that is fixed to the inner wall of the slide 13. The top end of the limiting block 14 passes through the slide 13 and extends to the outside.

[0065] Pulling the limiting block 14 will cause the limiting block 14 to move, which will compress the spring 15. When one end of the limiting block 14 moves out of the dustproof plate 23, the limiting block 14 can release the limiting of the dustproof plate 23. Personnel can then open the dustproof plate 23 upwards to ensure that when not in use, personnel can cover the cleaning tank 3 through the dustproof plate 23 to prevent dust from entering the cleaning tank 3. This makes it more convenient that the dust in the cleaning tank 3 does not need to be cleaned before the next use.

[0066] Example 5:

[0067] This embodiment provides a vacuum quenching device for bearing steel. In addition to the technical solutions of the above embodiments, it also has the following technical features: one end of the limiting block 14 is inserted into the dustproof plate 23, and one end of the limiting block 14 has an inclined structure.

[0068] Specifically, it is ensured that one end of the limiting block 14 can be inserted into the dustproof plate 23, so that the dustproof plate 23 can squeeze the limiting block 14 to move when closed.

[0069] Example 6:

[0070] This embodiment provides a vacuum quenching device for bearing steel. In addition to the technical solutions of the above embodiments, it also has the following technical features: the heating wire 21 is fixedly connected to the inner wall of the groove 16; the mounting plate 19 is tightly welded to the inner wall of the groove 16; the fan blade 20 is rotatably connected to the mounting plate 19; the motor 22 is fixedly connected to the mounting plate 19; the output ends of several motors 22 all pass through the mounting plate 19 and are coaxially connected to several fan blades 20 respectively; and the output shaft of the motor 22 is rotatably connected to the mounting plate 19.

[0071] This ensures the structural stability of the heating wire 21, the mounting plate 19, and the motor 22, guarantees that the fan blade 20 can rotate normally on the mounting plate 19, and guarantees that the output shaft of the motor 22 can rotate normally within the mounting plate 19.

[0072] Example 7:

[0073] This embodiment provides a vacuum quenching device for bearing steel. In addition to the technical solutions of the above embodiments, it also has the following technical features: the groove 16 is located above the drain basket 4.

[0074] Among these measures, it is essential to ensure the structural stability of the groove 16 and the drain basket 4.

[0075] Working principle: When in use, the operator can first pull the limiting block 14. The movement of the limiting block 14 will compress the spring 15 and move it until one end of the limiting block 14 moves out of the dustproof plate 23. At this time, the limiting block 14 can release the limiting of the dustproof plate 23, and the operator can open the dustproof plate 23 upwards. This ensures that when not in use, the operator can cover the cleaning tank 3 through the dustproof plate 23 to prevent dust from entering the cleaning tank 3. This makes it convenient that the dust in the cleaning tank 3 does not need to be cleaned before the next use.

[0076] Then, the personnel can put the bearing steel that needs to be quenched into the cleaning tank 3 for pretreatment. After the treatment is completed, the personnel can directly start the motor 12. The output shaft of the motor 12 will drive the threaded rod 10 to rotate. Under the action of the thread, the rotation of the threaded rod 10 will drive the sliding rod 9 to move upward. The upward movement of the sliding rod 9 will drive the moving plate 1 5 to move upward. The upward movement of the moving plate 1 5 will drive the drain basket 4 to move upward. The upward movement of the drain basket 4 will drive the moving plate 2 6 to move upward. The upward movement of the moving plate 2 6 will drive the limit rod 7 to move within the base 1. The limit rod 7 can maintain the stability of the drain basket 4 when it moves. At the same time, the upward movement of the drain basket 4 will drive the treated bearing steel to move upward until the bearing steel in the drain basket 4 leaves the water surface in the cleaning tank 3. At this time, the drain basket 4 can drain the water from the bearing steel, ensuring that the drain basket 4 can be automatically raised without the need for manual raising and lowering of the drain basket 4, and without the need to use fixing bolts for fixing, avoiding the situation where the fixing bolts are lost.

[0077] At this time, the drain basket 4 will be located on one side of several air outlets 18. Then, personnel can start several motors 22. The output ends of several motors 22 will drive several fan blades 20 to rotate. The rotation of several fan blades 20 can draw outside air into the groove 16 through the filter screen 17. At the same time, the filter screen 17 can filter dust in the air to prevent dust from entering the groove 16. At the same time, the heating wire 21 is energized. The air blown out by several fan blades 20 will be heated by the heating wire 21 and then blown into the bearing steel in the drain basket 4 through several air outlets 18. At this time, the bearing steel in the drain basket 4 can be dried to ensure that the bearing steel in the drain basket 4 can be dried quickly and that the surface of the bearing steel will not contain moisture during quenching, so as to avoid affecting the quality of the bearing steel after quenching.

[0078] After pretreatment, personnel can remove the bearing steel from the drain basket 4 and place it into the vacuum quenching chamber 2 for vacuum quenching treatment.

[0079] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
