Description

Technical Field

[0001] This invention relates to the field of quenching oil technology, specifically to a circulating quenching oil equipment and method for bearing quenching. Background Technology

[0002] During the production process of bearings, quenching is required to increase their strength. The purpose of quenching is to transform supercooled austenite into martensite or bainite to obtain a martensitic or bainitic structure. This is then followed by tempering at different temperatures to significantly improve the rigidity, hardness, wear resistance, fatigue strength, and toughness of the steel, thereby meeting the different usage requirements of various mechanical parts and tools. Quenching oil is a commonly used process oil in heat treatment, used as a quenching medium. Quenching oil needs to ensure good performance in order to achieve its intended effect. When quenching oil is used for a long time, impurities and oil residue increase, and the temperature rises, which affects the performance and thus the quality of the metal.

[0003] Chinese Patent CN112619228B discloses a quenching device with an intelligent filtration mechanism for motor bearing production. This quenching device includes a filter box, a first water pump, and a second water pump. Used quenching oil is drawn out, filtered, and then poured into another cooling device. When impurities appear in the quenching oil in this cooling device, it continues to be filtered back into the initial cooling device, forming a cycle. However, this quenching device filters the quenching oil using a filter screen. During filtration, oil residue accumulates on one side of the filter screen. Because the first water pump continuously supplies used quenching oil to this side, the oil residue accumulates and increases in height over time. This results in a large amount of quenching oil being stored between the oil residue side and the inside of the filter box, causing the quenching oil to decrease continuously during circulation. Furthermore, the device uses only one filter screen, resulting in a small mesh size that easily leads to clogging during use.

[0004] Based on this, a circulating quenching oil equipment and method for bearing quenching is provided, which can eliminate the drawbacks of existing equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a circulating quenching oil equipment and method for bearing quenching, so as to solve the problem in the prior art that oil residue easily clogs the filter screen, thereby affecting the filter screen's ability to circulate and filter quenching oil.

[0016] In one alternative: the third transmission tube is provided with a number of heat dissipation fins.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention facilitates multiple filtrations of the quenching oil inside the quenching box by setting a first filter plate and a second filter plate. A first scraper is set at the upper end of the first filter plate, and the first scraper is driven to reciprocate along the axis of the guide slide rod by a drive shaft and a first rotating ring, which facilitates the cleaning of impurities at the upper end of the first filter plate. At the same time, the first rotating ring and the drive shaft facilitate the stirring and mixing of the quenching oil inside the quenching box by the first stirring plate and the second stirring plate, thereby making the quenching oil inside the quenching box uniformly mixed and preventing the local temperature of the quenching oil inside the quenching box from being too high, which would affect the quenching of the bearing.

[0019] 2. This invention uses a water pump to draw quenching oil from inside the quenching chamber to the installation box for secondary filtration. As the quenching oil flows, the first fan blade drives the second scraper to rotate, facilitating the cleaning of impurities on the upper part of the second filter plate. Simultaneously, by fixing several push rods to the upper part of the fixed plate, when the filter holes on the upper part of the second filter plate are blocked, gravity causes the second filter plate to slide along the inside of the installation box, and the push rods can unclog the filter holes on the upper part of the second filter plate, thus preventing clogging. This solves the problem of the second filter plate being easily clogged by impurities, affecting the circulation and filtration of the quenching oil.

[0020] 3. This invention, by setting up several cooling plates and a liquid storage tank, uses a second motor to drive a second fan blade and a second rotating ring to rotate. The second rotating ring, through several guide blocks and a push rod, facilitates the delivery of liquid from the bottom of the cooling tank to the spray pipe. The spray pipe sprays the liquid onto a third transmission pipe. The second fan blade generates airflow, which accelerates the heat dissipation of the quenching oil inside the third transmission pipe. Simultaneously, the cooling plates, in conjunction with a copper plate, facilitate the cooling of the liquid at the bottom of the cooling tank and reduce the internal temperature of the cooling tank, thereby increasing the heat dissipation efficiency of the quenching oil inside the third transmission pipe. The cooled quenching oil is then re-transported back into the quenching tank through a fourth transmission pipe for recycling, thus increasing the practicality of the circulating quenching oil equipment.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Example 1

[0032] In one embodiment, such as Figures 1-8As shown, a circulating quenching oil device for bearing quenching includes a quenching box 11 and a cooling box 35. Several support legs are fixedly provided at the bottom of the quenching box 11. A placement rack 12 is fixedly provided inside the quenching box 11. A first filter plate 13 is fixedly provided inside the quenching box 11 at a position corresponding to the lower position of the placement rack 12. A first transmission pipe is fixedly connected to the input end of a water pump 20 on one side of the quenching box 11. One end of the first transmission pipe is connected to the interior of the quenching box 11. A second transmission pipe is connected to the output end of the water pump 20. One end of the second transmission pipe is connected to a mounting box 21. The mounting box 21 is fitted inside the cooling box 35. A second filter plate 23 is slidably disposed inside the mounting box 21. The output end of the mounting box 21 is connected to one end of a third transmission pipe 31. The output end of the third transmission pipe 31 is connected to a fourth transmission pipe... One end of the pipe is connected, and the other end of the fourth transmission pipe is connected to the inside of the quenching box 11. The quenching box 11 is equipped with a scraping mechanism to facilitate the cleaning of impurities on the upper end of the first filter plate 13. The mounting box 21 is equipped with a cleaning mechanism to facilitate the cleaning of impurities on the upper end of the second filter plate 23 and to prevent the second filter plate 23 from being blocked. The cooling box 35 is equipped with a heat dissipation mechanism at the position corresponding to the third transmission pipe 31 to facilitate the cooling of the quenching oil inside the third transmission pipe 31. The scraping mechanism facilitates the cleaning and collection of impurities on the upper end of the first filter plate 13, the cleaning mechanism facilitates the cleaning and collection of impurities on the upper end of the second filter plate 23, and at the same time facilitates the prevention of the second filter plate 23 from being blocked. The heat dissipation mechanism facilitates the cooling of the quenching oil inside the third transmission pipe 31, thereby facilitating the recycling of the quenching oil inside the quenching box 11.

[0033] The scraping mechanism includes a first scraper 17, the bottom end of which is in close contact with the upper end of the first filter plate 13. Guide rods are slidably provided in the circular through holes at both ends of the first scraper 17, and both guide rods are fixedly installed inside the quenching box 11. A fixing pin is slidably provided in the guide groove at the upper end of the first scraper 17, and the fixing pin is fixedly installed at the bottom end of the first rotating ring 14. Several first stirring plates are fixedly installed inside the first rotating ring 14, and one end of each of the first stirring plates is fixedly connected to a fixed column. A fixed shaft is fixedly installed at the upper end of the fixed column, and one end of the fixed shaft is rotatably mounted at the bottom end of the placement frame 12. A first conical friction wheel is fixedly installed on the fixed column, and second conical friction wheels are symmetrically fitted on the first conical friction wheels. A drive shaft 15 is fixedly installed on one side of each of the second conical friction wheels, and several second stirring plates are fixedly installed on each drive shaft 15. The two drive shafts 15 are respectively rotatably mounted on one side of the quenching box 11. Inside the hole, one end of the drive shaft 15 is fixedly connected to the output end of the first motor 16 on one side of the quenching box 11. The bottom end of the first filter plate 13 is provided with a collection component to facilitate the collection of impurities. In use, when it is necessary to clean the impurities on the upper end of the first filter plate 13, the first motor 16 is started. The output end of the first motor 16 drives one drive shaft 15 to rotate. The second conical friction wheel at one end of the drive shaft 15 cooperates with the first conical friction wheel, thereby driving the first rotating ring 14 and the other drive shaft 15 to rotate. When the first rotating ring 14 and the drive shaft 15 rotate, the first stirring plate and the second stirring plate facilitate the mixing of the quenching oil inside the quenching box 11, preventing the quenching oil temperature inside the quenching box 11 from being too high. At the same time, when the first rotating ring 14 rotates, it drives the fixed pin to rotate. The fixed pin slides in the guide groove at the upper end of the first scraper 17, thereby causing the first scraper 17 to move back and forth along the axis of the guide slide rod, thereby cleaning the impurities on the upper end of the first filter plate 13.

[0034] The collection assembly includes two symmetrically arranged filter boxes 18, which are fixedly positioned at the corresponding rectangular perforation at the bottom of the first filter plate 13. Each filter box 18 has several filter holes. A discharge pipe is connected to the bottom of each filter box 18, and a valve is fitted onto the discharge pipe. A first collection box 19 is fitted to one end of each discharge pipe. The bottom of the filter box 18 is inclined. In use, when the first scraper 17 pushes impurities from the upper end of the first filter plate 13 to the position corresponding to the rectangular perforation at the upper end of the first filter plate 13... Impurities fall into the filter box 18 through the rectangular perforation. Since the width of the opening at the top of the filter box 18 is smaller than the width at the bottom, the re-flow of impurities is reduced. Subsequently, the impurities enter the first collection box 19 through the discharge pipe. As the amount of impurities inside the first collection box 19 increases, the quenching oil inside the first collection box 19 is squeezed out. When it is necessary to clean the impurities inside the first collection box 19, the valve is used to close one end of the discharge pipe, and the first collection box 19 is removed to clean the impurities inside the first collection box 19.

[0035] The cleaning mechanism includes two symmetrically arranged second scrapers 24, with one end of each scraper 24 fixedly connected. The bottom end of each scraper 24 is in close contact with the top end of a second filter plate 23. The bottom end of each filter plate 23 is fixedly connected to one end of a plurality of first return springs 30. The other end of each first return spring 30 is fixedly connected to the top end of a fixing plate 28 inside the mounting box 21. The fixing plate 28 has a plurality of arc-shaped through holes on its upper end. A mounting shaft is fixedly mounted on the upper end of each scraper 24. A plurality of first fan blades 22 are fixedly mounted on one end of the mounting shaft. A rotating plate is rotatably mounted on the mounting shaft. The rotating plate is fixedly mounted inside one end of a second transmission pipe. A discharge pipe is connected to the mounting box 21. A feed pipe is sleeved on the discharge pipe and is connected to a second collection box 25. A fixing bracket is fitted on the second collection box 25. Fixing slide rods are symmetrically mounted on the fixing bracket. The fixed slide rod is slidably disposed in a sliding hole on one side of the quenching box 11. A threaded rod 26 is rotatably disposed on one side of the fixed bracket. A threaded hole is disposed on one side of the quenching box 11 corresponding to the position of the threaded rod 26. In use, when the water pump 20 draws quenching oil from inside the quenching box 11, the quenching oil enters the installation box 21 through the second transmission pipe. When the quenching oil enters the installation box 21, the quenching oil drives the installation shaft to rotate through the first fan blade 22. The installation shaft drives the two second scrapers 24 to rotate. When the second scrapers 24 rotate, they can scrape the impurities on the upper end of the second filter plate 23 to the position corresponding to the discharge pipe, and then enter the second collection box 25 through the feed pipe for collection. When it is necessary to clean the impurities inside the second collection box 25, the threaded rod 26 is rotated. Under the action of the thread, the fixed bracket drives the second collection box 25 to move away from the installation box 21, thereby removing the second collection box 25.

[0036] Several top rods 29 are fixedly provided on the upper end of the fixed plate 28. When the filter holes on the second filter plate 23 are blocked during use, the quenching oil inside the mounting box 21 increases, thereby causing the second filter plate 23 to slide inside the mounting box 21. When the second filter plate 23 slides to the position corresponding to one end of the top rod 29, one end of the top rod 29 is inserted into the filter hole on the second filter plate 23, thereby cleaning the filter hole on the second filter plate 23.

[0037] The second collection box 25 is fixedly provided with a third filter plate 27, which is inclined. The bottom of the second collection box 25 is connected to an oil outlet pipe. One end of the oil outlet pipe is connected to one end of the oil inlet pipe on the mounting box 21. In use, when the second scraper 24 scrapes the impurities on the upper end of the second filter plate 23 into the second collection box 25, the impurities and quenching oil fall onto the upper end of the third filter plate 27 at the same time. The quenching oil penetrates through the impurities to the bottom of the second collection box 25 and enters the mounting box 21 through the oil outlet pipe for recycling.

[0038] The heat dissipation mechanism includes several cooling plates 33 and spray pipes 36. The cooling plates 33 are fixedly disposed inside one side of the cooling tank 35. The spray pipes 36 are symmetrically arranged and fixed inside the cooling tank 35. Each spray pipe 36 has several atomizing nozzles on its inclined side. One end of each spray pipe 36 is connected to a liquid outlet pipe, which is fitted with a first one-way valve. The other end of the liquid outlet pipe is connected to a liquid storage tank 37, which is fixedly disposed inside the cooling tank 35. An inlet pipe is connected to the liquid storage tank 37, which is fitted with a second one-way valve. Inside the tank 37, a push plate 38 is slidably mounted. A push rod is fixedly mounted on one side of the push plate 38. A second return spring 39 is fixedly mounted between the circular plate side of the push rod and the side of the liquid storage tank 37. One end of the second return spring 39 is fitted with a guide block 40. Several guide blocks 40 are fixedly mounted on one side of the second rotating ring 41. Several second fan blades 42 are fixedly mounted inside the second rotating ring 41. One end of each second fan blade 42 is fixedly mounted on the output shaft of the second motor 43. The second motor 43 is fixedly mounted in a mounting groove on one side of the cooling tank 35. In use, when it is necessary to add quenching oil to the third transmission pipe 31... During heat dissipation, the second motor 43 is started. The output of the second motor 43 drives the second rotating ring 41 to rotate via the second fan blade 42. The rotation of the second fan blade 42 accelerates airflow. The second rotating ring 41 drives several guide blocks 40 to rotate. When the guide blocks 40 contact one end of the push rod, the guide blocks 40 push the push plate 38 to slide inside the liquid storage tank 37 via the push rod. At this time, the first one-way valve opens and the second one-way valve closes, allowing the liquid inside the liquid storage tank 37 to enter the spray pipe 36. The spray pipe 36 sprays the liquid out through several atomizing nozzles. Under the action of the second fan blade 42, the liquid is sprayed... The liquid vaporizes on the third transmission pipe 31 due to its high surface temperature. Under the action of the cooling plate 33, the liquid in the air is liquefied to form water droplets, which lowers the temperature of the water droplets and the inside of the cooling tank 35. The water droplets fall to the bottom of the cooling tank 35, making it easier for the liquid inlet pipe to draw liquid. When the guide block 40 disengages from one end of the push rod, the push plate 38 returns to its initial position under the action of the second return spring 39. At this time, the first one-way valve closes and the second one-way valve opens, allowing the liquid inlet pipe to draw liquid from the bottom of the cooling tank 35 into the storage tank 37.

[0039] A plurality of copper plates 34 are fixedly provided on one side of the cooling plate 33. One end of the plurality of copper plates 34 is in close contact with the bottom end of the cooling box 35. When the cooling plate 33 is working, the plurality of copper plates 34 on the side of the cooling plate 33 near the bottom end of the cooling box 35 can facilitate the conduction of heat, thereby facilitating the cooling of the coolant at the bottom end of the cooling box 35, thereby increasing the heat dissipation effect of the quenching oil inside the third transmission pipe 31.

[0040] Example 2

[0041] The difference from Embodiment 1 is that the third transmission tube 31 is provided with a number of heat dissipation fins 32, which facilitates the rapid heat dissipation of the quenching oil inside the third transmission tube 31 during use.

[0042] The above embodiment discloses a circulating quenching oil device for bearing quenching. When quenching a bearing is required, quenching oil is poured into the quenching chamber 11. The bearing is then placed on the upper end of the placement rack 12 inside the quenching chamber 11. Simultaneously, a first motor 16 is started. The output of the first motor 16 drives a transmission shaft 15 to rotate. A second conical friction wheel at one end of the transmission shaft 15 engages with a first conical friction wheel, thereby driving a first rotating ring 14 and another transmission shaft 15 to rotate. When the first rotating ring 14 and the transmission shaft 15 rotate, the first and second stirring plates facilitate mixing of the quenching oil inside the quenching chamber 11, preventing the oil from becoming stagnant inside the quenching chamber 11. The quenching oil temperature is too high, and the diameter of the filter holes at the upper end of the first filter plate 13 is larger than that at the upper end of the second filter plate 23. The first filter plate 13 filters larger impurities, and the bottom of the quenching box 11 is tilted. At the same time, when the first rotating ring 14 rotates, it drives the fixed pin to rotate. The fixed pin slides in the guide groove at the upper end of the first scraper 17, thereby causing the first scraper 17 to move back and forth along the axis of the guide rod, thus cleaning the impurities at the upper end of the first filter plate 13. When the first scraper 17 pushes the impurities at the upper end of the first filter plate 13 to the position corresponding to the rectangular perforation at the upper end of the first filter plate 13, the impurities fall into the filter box 18 through the rectangular perforation. And because the filter box 18 The width of the upper opening is smaller than the width of the bottom of the filter box 18, thereby reducing the re-flow of impurities. Subsequently, the impurities enter the first collection box 19 through the discharge pipe. As the amount of impurities inside the first collection box 19 increases, the quenching oil inside the first collection box 19 is squeezed out. At the same time, when the water pump 20 draws quenching oil from the quenching box 11, the quenching oil enters the mounting box 21 through the second transmission pipe. When the quenching oil enters the mounting box 21, the quenching oil drives the mounting shaft to rotate through the first fan blade 22. The mounting shaft drives the two second scrapers 24 to rotate. When the second scrapers 24 rotate, they can scrape the impurities on the upper end of the second filter plate 23 to the corresponding position of the discharge pipe, thereby entering the feed pipe. The second collection box 25 collects impurities and quenching oil, which fall simultaneously onto the upper part of the third filter plate 27. The quenching oil permeates through the impurities to the bottom of the second collection box 25 and enters the mounting box 21 through the oil outlet pipe for recycling. When the filter holes on the second filter plate 23 become clogged, the amount of quenching oil inside the mounting box 21 increases, causing the second filter plate 23 to slide inside the mounting box 21. When the second filter plate 23 slides to the position corresponding to one end of the push rod 29, one end of the push rod 29 is inserted into the filter hole on the second filter plate 23, thereby cleaning the filter hole on the second filter plate 23. The filtered quenching oil enters the third transmission pipe 31, and the second motor 43 is started.The output of the second motor 43 drives the second rotating ring 41 to rotate via the second fan blade 42. The rotation of the second fan blade 42 accelerates airflow. The second rotating ring 41 drives several guide blocks 40 to rotate. When a guide block 40 contacts one end of a push rod, the guide block 40 pushes the push plate 38 to slide inside the liquid storage tank 37 via the push rod. At this time, the first one-way valve opens and the second one-way valve closes, allowing the liquid inside the liquid storage tank 37 to enter the spray pipe 36. The spray pipe 36 sprays the liquid through several atomizing nozzles. Under the action of the second fan blade 42, the liquid is sprayed onto the third transmission pipe 31. Due to the high surface temperature of the third transmission pipe 31, the liquid vaporizes and... Under the action of 3, the liquid in the air is liquefied to form water droplets, which simultaneously lowers the temperature of the water droplets and the inside of the cooling tank 35. The water droplets fall to the bottom of the cooling tank 35, facilitating the inlet pipe to draw liquid. When the guide block 40 disengages from one end of the push rod, the push plate 38 returns to its initial position under the action of the second return spring 39. At this time, the first one-way valve closes and the second one-way valve opens, allowing the inlet pipe to draw liquid from the bottom of the cooling tank 35 into the storage tank 37. Simultaneously, under the action of several heat dissipation fins 32, the heat dissipation of the quenching oil inside the third transmission pipe 31 is accelerated.
