Description

Technical Field

[0001] This utility model relates to the field of bearing parts manufacturing technology, specifically to a heat treatment equipment for bearing parts raw materials. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. In order to improve the performance of bearings and extend their service life, during the bearing production and assembly process, it is necessary to perform heat treatment on their components, such as rollers, to eliminate the internal stresses that occurred during the processing.

[0003] A search revealed an existing patent (publication number: CN219637289U) that discloses a heat treatment device for processing bearing rollers. The device includes a protective box with a sealing cover snapped onto its top. A drive mechanism, comprising an upper drive assembly and a lower drive assembly, is located inside the protective box. A heating mechanism is also installed within the protective box. The advantages are: the drive mechanism, including the upper and lower drive assemblies, drives the rollers in the placement tray to rotate back and forth, resulting in more uniform heating; the placement tray is divided into several small placement sections by a partition, preventing the rollers from being densely packed while providing sufficient movement space for each section, further enhancing heating uniformity; and the spiral air duct creates a vortex of hot air within the protective box, extending the heat exchange time and increasing heat exchange efficiency.

[0004] However, the above solution is inconvenient for unloading. After the rollers are heat-treated, the high temperature of the rollers makes it difficult for workers to remove them. Waiting for them to cool naturally will leave the heating furnace idle, which will reduce the efficiency of the roller heat treatment and make it inconvenient to use.

[0005] In view of this, the present invention proposes a heat treatment equipment for bearing parts raw materials. Summary of the Invention

[0043] Example 2

[0044] Based on Example 1, a preferred embodiment of the bearing component raw material heat treatment equipment provided by this utility model is as follows: Figures 1 to 5 As shown: The filter assembly 3 includes: a mounting groove 303 on the front of the filter box 2, bolt holes 304 on the front of the filter box 2 on both sides of the mounting groove 303; a sealing plate 301 movably connected to the front of the filter box 2, a filter hopper 307 extending into the filter box 2 fixedly connected to the back of the sealing plate 301, and fixing bolts 306 movably connected to the four corners of the front of the sealing plate 301, which penetrate the sealing plate 301 and are threaded into the bolt holes 304; and a flow guide platform 302 fixedly connected to the upper end of the inner wall of the filter box 2.

[0045] In this embodiment, during the process of hot air circulation inside the heating furnace 4 when the hot air blower 1 is operating, the filter hopper 307 can be used to filter and remove dust from the air entering the inside of the filter box 2, preventing dust and other impurities from being circulated by the hot air to all spaces inside the heating furnace 4. At the same time, the filter hopper 307 can be slid out periodically for easy centralized treatment of the dust and other impurities filtered inside the filter hopper 307 and thorough cleaning of the filter hopper 307 to prevent blockage.

[0046] In a further preferred embodiment of the present utility model, both sides of the inner wall of the diversion platform 302 are inclined planes, and the cross-sectional area of the bottom opening of the diversion platform 302 is smaller than the cross-sectional area of the top opening of the filter hopper 307.

[0047] In this embodiment, the inclined diversion platform 302 is used to guide the hot air so that it enters the inside of the filter hopper 307 more concentratedly for filtering and dust removal.

[0048] In a further preferred embodiment of the present utility model, one end of the surface of the sealing plate 301 is fixedly connected with a high-temperature resistant sealing gasket 308, and the shape of the high-temperature resistant sealing gasket 308 is a square frame.

[0049] In this embodiment, the square-frame-shaped high-temperature resistant sealing gasket 308 is used to improve the sealing performance of the engagement installation of the sealing plate 301 and the inside of the installation groove 303, preventing heat leakage.

[0050] In a further preferred embodiment of the present utility model, anti-slip lines 305 are equiangularly arranged on the surface of the nut of the fixing bolt 306, and the shape of the anti-slip lines 305 is arc-shaped.

[0051] In this embodiment, the arc-shaped anti-slip lines 305 are used to increase the anti-slip friction force when the user rotates the fixing bolt 306 with their fingers.

[0052] The working principle of this utility model: First, the reduction motor 12 is used to make the roller 8 rotate, which带动 the feed hopper 9 to rotate to the upper side. Then, an appropriate amount of rollers are added through the feed hopper 9. After that, the servo motor 1401 is started to带动 the threaded rod 1406 to rotate. By using the threaded fit of the threaded rod 1406 and the threaded block 1404, the threaded block 1404 slides to带动 the connecting plate 1402 to slide, so that the sealing partition 11 and the roller 8 slide into the inside of the heating furnace 4, and the sealing partition 11 completely blocks one side of the through groove 10. At the same time, the high-temperature resistant sealing ring 15 is used to further improve the sealing performance of their engagement.

[0053] Then, the heating tube 7 is started to heat the rollers inside the drum 8. At the same time, the reduction motor 12 is started to make the drum 8 rotate, which facilitates the uniform heating of the rollers inside the drum 8. The temperature sensor 6 is used to detect the internal temperature of the heating furnace 4, and the controller 13 is used to regulate the heating tube 7 to keep the internal temperature of the heating furnace 4 constant within a certain range. Then, the hot air blower 1 is started to draw the hot air inside the heating furnace 4 into the filter box 2, and the air is filtered and dusted through the filter bucket 307. The hot air is then transported back into the heating furnace 4 through the duct to achieve hot air circulation and further improve the uniformity of the roller heating.

[0054] After the heat treatment is completed, the servo motor 1401 can be started again, so that the connecting plate 1402 slides and drives the roller 8 to slide to the outside of the heating furnace 4. At this time, the heat insulation plate 5 can block the through groove 10 to reduce the leakage of heat inside the heating furnace 4. Then, the reduction motor 12 is started to move the feed hopper 9 to the bottom and place the receiving bucket below it. After opening the sealing plate on the feed hopper 9, the heat-treated rollers inside the roller 8 can be discharged. Then, the reduction motor 12 is started again to rotate the feed hopper 9 to the top and add rollers again. The above operation is repeated to realize the heat treatment of the rollers. There is no need to wait for the rollers inside the roller 8 to cool naturally. They can be discharged directly and new rollers can be added, which improves the efficiency of the heat treatment of the rollers.

[0055] Meanwhile, the fixing bolt 306 can be rotated periodically until it is completely disengaged from the bolt hole 304. Then, the sealing plate 301 can be pulled by the handle on the sealing plate 301 to slide the filter 307 out. This facilitates the centralized treatment of dust and other impurities filtered inside the filter 307 and allows for thorough cleaning and clogging prevention of the filter 307. During installation, the filter 307 can be used to improve the sealing performance after the sealing plate 301 and the mounting groove 303 are engaged. Then, the fixing bolt 306 can be tightened into the bolt hole 304.

The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.
