Description

Technical Field

[0001] This invention relates to the field of quenching equipment technology, specifically to heat treatment quenching equipment for rolling elements. Background Technology

[0002] The heat treatment quenching equipment for rolling elements is a metal heat treatment equipment specifically designed for rolling elements (such as balls, rollers, cylinders, etc.) in components such as bearings, gears, and drive shafts. Its core purpose is to significantly improve the surface hardness, wear resistance, and fatigue life of rolling elements through the quenching process. The equipment is widely used in machinery manufacturing, automobiles, aerospace and other fields.

[0003] Vertical CNC quenching equipment is a high-precision device that integrates precision machining, heat treatment and intelligent control. It is widely used in the surface hardening treatment of metal parts such as gears, shafts and molds. Its working principle is based on the combination of precise control by CNC technology and thermodynamic quenching process. Heating is achieved by generating eddy currents on the surface of the workpiece through a high-frequency alternating magnetic field, which rapidly raises the temperature to the critical temperature (such as 850°C). Then, the quenching medium (water, oil, polymer solution) is sprayed onto the surface of the workpiece at high speed through a nozzle to achieve instantaneous cooling.

[0004] Existing vertical quenching equipment, when processing long shaft-type metal parts, clamps and positions the rolling element workpiece, then a rotating component inside the equipment drives the rolling element workpiece to rotate. An electromagnetic coil in the heating system heats the surface of the rolling element workpiece, and a cooling component is installed below the electromagnetic coil to cool the workpiece surface. Furthermore, a lifting platform is located at the bottom of the cooling and heating systems, which moves the cooling and heating systems up and down on the outer wall of the rolling element, facilitating all-around processing of long shaft-type workpieces. However, when the quenching equipment rapidly cools the workpiece, it generates a large amount of smoke, which may carry impurities. In particular, high-carbon steel may oxidize at high temperatures to form iron oxide particles. Metal chips and oxides falling from the electromagnetic coil or quenching tank may also mix with the cooling medium and be carried away by the airflow, escaping with the smoke. Over prolonged operation, these impurities in the smoke will float around the equipment, reducing the lifespan of the electronic components inside and impacting the air environment of the operating workshop. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a heat treatment quenching apparatus for rolling elements to solve the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heat treatment quenching device for rolling elements, comprising a device housing and a drive motor installed within the device housing. The output end of the drive motor is equipped with a rotating component. The device also includes a cooling component, a heating system, and a lifting platform for moving the cooling component and the heating system. Adsorption components for purifying the gas surrounding the rolling element to be processed are provided at both ends of the device housing.

[0007] By adopting the above technical solution, the bevel gear set drives the impeller to rotate and adsorb smoke and water vapor on the surface of the rolling workpiece. The water vapor is then filtered through the first and second filter plates, reducing the impurity content in the water vapor and purifying the gas itself to reduce air pollution and improve the workshop air environment. This also reduces the damage of impurities to equipment components. Through the setting of the auxiliary moving rod, which is connected to the lifting platform on the inner wall of the device housing, when the lifting platform moves the electromagnetic coil upward, the auxiliary moving rod moves the adsorption component upward to specifically adsorb the smoke around the electromagnetic coil and the cooling system, improving the working efficiency of the adsorption component and also improving the practicality of the device to a certain extent.

[0029] The embodiments of the present invention will now be described.

The configuration of component 5 involves the rotating component 3 driving the rolling workpiece to rotate, while the output end of the drive motor of the rotating component 3 is fitted with a belt 54. The belt 54 drives the driven wheel 53 to rotate, which in turn causes the bevel gear set 51 to drive the impeller 560 to rotate, adsorbing smoke and water vapor on the surface of the rolling workpiece. The water vapor is then filtered through the first filter plate 520 and the second filter plate 530, reducing the impurity content in the water vapor and purifying the gas itself to reduce air pollution, improve the air environment in the workshop, and reduce the damage of impurities to equipment components. With the auxiliary moving rod 6 connected to the lifting platform 2 on the inner wall of the device housing 1, when the lifting platform 2 moves the electromagnetic coil upward, the auxiliary moving rod 6 moves the adsorption component 5 upward to specifically adsorb smoke around the electromagnetic coil and the cooling system, improving the working efficiency of the adsorption component 5 and also improving the practicality of the device to a certain extent.

[0039] Second embodiment:

[0040] Please see Figure 4 , Figure 5The difference between Embodiment 2 and Embodiment 1 is that, while retaining the features of Embodiment 1, a fixing block 61, a first limiting block 62, and a second limiting block 63 are added to the outer wall of the support rod 60 to improve the stability of the support rod 60 when it drives the adsorption component 5 to move upward.

[0041] The outer wall of the device housing 1 is provided with a groove 10, and a fixing block 61 is installed on the outer wall of the support rod 60. The groove 10 and the fixing block 61 are engaged, allowing the fixing block 61 to move within the groove 10. Furthermore, the support rod 60 is connected to the outer wall of the housing 50 through a first limiting block 62 and a second limiting block 63, which reduces the shaking generated by the impeller 560 and the bevel gear set 51 during rotation, extends the service life of the adsorption assembly 5, and improves the stability of the adsorption assembly 5 during operation. The setting of the fixing block 61, the first limiting block 62 and the second limiting block 63 not only improves the stability of the support rod 60 during movement, but also effectively supports the outer wall of the housing 50.

[0042] In practical operation, this invention: When machining long-shaft metal workpieces, the rolling element workpiece is first placed on top of the rotating assembly 3, and the top of the rolling element workpiece is positioned using a fixture. The heating system 8 and cooling assembly 7 are fitted onto the outer wall of the rolling element workpiece. Then, the rotating assembly 3 is activated by a control button to rotate the rolling element workpiece. The electromagnetic coil in the heating system 8 and the cooling assembly 7 work on the outer wall of the rolling element workpiece (the lifting platform 2, cooling assembly 7, and heating system 8 are existing technologies and will not be described in detail here). Simultaneously, while the rotating assembly 3 is rotating the rolling element workpiece, two sets of belts 54 are fitted onto the output end of the drive motor at one end of the rotating assembly 3. The belts 54 are positioned opposite each other, and the other end of the belts 54 is fitted with a... The driven wheel 53 and the driven wheel 53 are movably connected to the protective shell 4. A telescopic rod 52 is installed on the top of the driven wheel 53, and a bevel gear set 51 is installed on the top of the telescopic rod 52. An impeller 560 is provided at the other end of the bevel gear set 51. The impeller 560 is fitted inside the outer shell 50. When the impeller 560 rotates at high speed, the blades push the air to move outward, generating centrifugal force. A low-pressure area is formed in the central area of ​​the impeller 560 due to the air being thrown out. External air is drawn in under the action of pressure difference to fill the low-pressure area. The drawn-in air is accelerated as the impeller 560 rotates and is finally discharged from the air outlet 510, forming a continuous airflow (e.g., an industrial centrifugal fan, powered by a Siemens SIMOTISC motor). The SD 322-4A has a rotation speed of 3000 rpm. The horizontal shaft rotation of the drive motor is converted into the vertical shaft rotation of the impeller 560 through the bevel gear set 51. The transmission ratio is 1:1 to keep the speed constant. Then the blades are radial and generate centrifugal airflow when rotating at high speed. This causes the bevel gear set 51 to drive the impeller 560 to rotate and adsorb a large amount of smoke and water vapor generated after the rolling workpiece is processed. Furthermore, under the force of the impeller 560's rotation, the gas inside the outer casing 50 passes through the second filter plate 530 to filter out impurities, and then flows out of the outer casing 50 after being purified by the first filter plate 520 and the third filter plate 540. This effectively reduces the impact of the gas on the workshop air and also reduces the impact of impurities on the electronic components inside the equipment. When the surface temperature of the ceramic membrane in the first filter plate 520 and the third filter plate 540 is lower than the water vapor dew point, water vapor condenses into water droplets. These water droplets can flow from the bottom of the outer casing 50 into a water storage tank for reuse. Secondly, the second filter... A positioning rod 570 is provided at one end of the filter plate 530. The bevel gear set 51 drives the impeller 560 to rotate and drives the small gear 561 to rotate, which in turn causes the large gear 562 to drive the positioning rod 570 to swing. A spring and a connecting block 574 are provided at the end of the positioning rod 570 near the second filter plate 530. A scraper 575 is installed between multiple sets of connecting blocks 574. The scraper 575 cleans the outer wall of the second filter plate 530, so that the impurities fall to the top of the third filter plate 540 in sequence for collection. The third filter plate 540 is engaged with the inner wall of the outer shell 50, making it easy to remove the third filter plate 540 from the outer shell 50 for cleaning. Furthermore, the support rod 60 is connected to the lifting platform 2 on the inner wall of the device housing 1, and a bearing 522 is installed at the other end of the support rod 60. The bearing 522 is sleeved on the top of the telescopic rod 52 and at the bottom of the bevel gear set 51. When the lifting platform 2 moves the heating system 8 and the cooling component 7 upward, the support rod 60 moves upward with the lifting platform 2, thereby causing the support rod 60 to move the spline shaft upward and move the position of the adsorption component 5 upward, so that the adsorption component 5 can specifically adsorb around the rolling workpiece, improving the adsorption effect. Secondly, the outer wall of the auxiliary moving rod 6 is equipped with a fixing block 61, a first limiting block 62 and a second limiting block 63. The outer surface of the device housing 1 is provided with a groove 10, which engages with the fixing block 61. The fixing block 61 moves within the groove 10 and is connected to the outer wall of the outer shell 50 through the first limiting block 62 and the second limiting block 63, which effectively improves the stability of the auxiliary moving rod 6 during movement and also supports the outer shell 50.
