Description

Technical Field

[0001] This invention relates to the field of mechanical parts processing, and specifically to a heat treatment system for ring-shaped parts. Background Technology

[0002] In the machinery industry, many ring-shaped parts require heat treatment during their production and processing, such as bearing rings and gear rings. These parts need to be heat-treated and then cooled during use to improve their wear resistance and other material properties.

[0003] Existing heat treatment methods for ring-shaped parts mostly employ heating induction coils to heat individual parts. This method is suitable for large ring-shaped parts but not for the heat treatment needs of small, high-volume ring-shaped parts. Furthermore, heated parts are often cooled by water spray or directly immersed in a cooling water tank. Both of these cooling methods have their drawbacks: the first method has a limited cooling rate, making it unsuitable for applications requiring rapid cooling; while the second method often involves infrequent water replacement or the use of an external cooling system, the water temperature in the tank still rises with each cooling cycle, affecting the cooling of subsequent parts and hindering the formation of the desired metallographic structure.

Detailed Implementation

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] A heat treatment system for ring-shaped parts includes a workstation 1, a lifting plate 2, a heating induction coil 10, a rotary lifting device 3, a drive assembly 4, and a power assembly 5. The workstation 1 is fixed on the ground, and four workstations are arranged around the workstation 1, which are arranged counterclockwise as loading workstation a, heat treatment workstation b, drying workstation c, and unloading workstation d.

[0037] A rotary table 6 is rotatably connected to the workstation 1. Four fixing fixtures 7 for fixing ring-shaped parts are rotatably connected to the rotary table 6. The drive assembly 4 is located on the workstation 1. The drive assembly 4 uses the relative rotational motion between the rotary table 6 and the workstation 1 to drive the fixing fixtures 7 to rotate automatically on the rotary table 6, so that the fixing fixtures 7 are in an upright state, facing upward and downward, at different workstations.

[0038] Four water buckets 8 are fixedly connected to the lifting plate 2, one of which is located at the heat treatment station b. A fixed plate 9 is rotatably connected to the lifting plate 2. A heating induction coil 10 corresponding to the water bucket 8 and a water supply pipe 11 are fixedly connected to the fixed plate 9. The rotary lifting device 3 is located below the lifting plate 2 and is used to drive a new water bucket 8 into the heat treatment station b and slowly lift it and the heating induction coil 10 to perform heat treatment and cooling on the ring-shaped parts on the fixed fixture 7.

[0039] The bottom of the water bucket 8 is provided with a drainage device 12, which enables the water bucket 8 to automatically drain water and seal during rotation; the power component 5 is used to drive the rotary table and the rotary lifting device 3 to move synchronously.

[0040] A dryer 13 is provided at the drying station c, and a feeding chute 14 is provided at the feeding station d. A temporary storage box 15 is provided at the bottom of the feeding chute 14.

[0041] In this embodiment, the fixing fixture 7 includes a support shaft 71, and a base 72 is fixedly connected to the outer end of the support shaft 71. A limiting tube 73 for fitting and fixing ring-shaped parts is fixedly connected to the base 72. A support structure 74 for limiting the falling of ring-shaped parts is provided inside the limiting tube 73.

[0042] In this embodiment, the support structure 74 includes a limiting motor 741 and support members 742. The limiting motor 741 is fixedly connected to the base 72. The output shaft of the limiting motor 741 is fixedly connected to a rotating shaft 743. The rotating shaft 743 is rotatably connected inside the limiting tube 73. A worm gear 744 is fixedly connected to the bottom of the rotating shaft 743. Four support members 742 are hinged to one end of the limiting tube 73 away from the base 72. A worm wheel 745 that meshes with the worm gear 744 is fixedly connected to the support member 742. The support member 742 plays a supporting and limiting role for the ring-shaped parts, preventing the ring-shaped parts from sliding down.

[0043] In this embodiment, the rotary lifting device 3 includes a turntable 31, a water collection tank 32, a hydraulic cylinder 33, and a rotating shaft 34. The turntable 31 has a circular groove 311, and the bottom of the water bucket 8 is located in the circular groove 311. When the turntable 31 rotates, it can drive the water bucket 8 to rotate together. The turntable 31 is rotatably connected to the water collection tank 32, and the water collection tank 32 is fixed to the ground. The center of the water collection tank 32 has a raised annular water-blocking structure 321. The bottom of the turntable 31 is fixedly connected to the rotating shaft 34, which is located in the annular water-blocking structure 321. The bottom of the water collection tank 32 has a drain outlet 322, which is connected to a cooling tower. The cooling water is cooled and then recycled.

[0044] In this embodiment, the drainage device 12 includes a baffle 121. The inner bottom of the water bucket 8 has a circular groove 81 with several drainage holes 82. The baffle 121 is located within the circular groove 81. A push rod 122 is fixedly connected to the bottom of the baffle 121. The push rod 122 is slidably connected to the water bucket 8. A universal ball 123 is provided at the bottom of the push rod 122. A spring 124 is sleeved on the push rod 122 between the universal ball 123 and the bottom of the water bucket 8. The inner bottom of the water collection tank 32... The unit is equipped with an arc-shaped lifting block 125, which is located in the area between the heating induction coil 10 and the water supply pipe 11. The lifting block 125 has a symmetrical structure that is low at both ends and high in the middle. When the water bucket 8 rotates 90 degrees counterclockwise from below the heating induction coil 10, the height of the lifting block 125 continues to increase until it reaches its highest point at 90 degrees. The push plate rises, and the drain hole 82 drains water. Then the water bucket 8 rotates 90 degrees counterclockwise again, and the universal ball 123 is at its lowest point. The push plate resets and blocks the drain hole 82.

[0045] In this embodiment, the drive assembly 4 includes a fixed bevel gear 41 and a rotating bevel gear 42. The fixed bevel gear 41 is fixedly connected to the center of the worktable 1. Each inner end of the support shaft 71 is fixedly connected to a rotating bevel gear 42 that meshes with the fixed bevel gear 41. The number of teeth on the rotating bevel gear 42 is half the number of teeth on the fixed bevel gear 41. Therefore, when the rotary table 6 rotates 90 degrees, the rotating bevel gear 42 meshes with the bevel gears that have half its own number of teeth, causing the support shaft 71 to rotate 180 degrees. In other words, when the rotary table 6 rotates 90 degrees, the support shaft 71 rotates 180 degrees.

[0046] In this embodiment, the power assembly 5 includes a drive motor 51, which is fixedly connected to the bottom of the workstation 1. The drive motor 51 has two output shafts. The upper output shaft is fixedly connected to the rotary table 6 via a connecting shaft 52, and the lower output shaft is fixedly connected to the transmission shaft 53. The transmission shaft 53 is rotatably connected to the support platform 54 provided below the workstation 1. Both the transmission shaft 53 and the rotating shaft 34 are provided with synchronous pulleys 55, and the two synchronous pulleys 55 are connected by a synchronous belt.

[0047] In this embodiment, the fixed plate 9 is provided with a limiting slide post 16, which is slidably connected to the fixed frame 17, and the fixed frame 17 is fixedly connected to the water collection tank 32. The limiting slide post 16 can restrict the rotation of the fixed plate 9. The fixed plate 9 is rotatably connected to the lifting plate 2, so that when the lifting plate 2 rotates, the fixed plate 9 can remain stationary, ensuring that the heating induction coil 10 and the water supply pipe 11 can always be aligned with the water bucket 8 at the corresponding position.

[0048] Working process and its principle:

[0049] At loading station a, the limiting tube 73 is in an upright position. At this time, the four supporting members 742 retract into the limiting tube 73, allowing the ring-shaped parts to be normally inserted into the limiting tube 73 from above. After a certain number of ring-shaped parts are inserted, the limiting motor 741 starts, driving the rotating shaft 743 to rotate, which in turn drives the worm gear 744 at the bottom of the rotating shaft 743 to rotate. The worm gear 744 meshes with the worm wheel 745 on the supporting member 742, causing the supporting member 742 to rotate outward and open, thereby limiting the ring-shaped parts.

[0050] The drive motor 51 drives the rotary table 6 to rotate 90 degrees counterclockwise on the workstation 1, and the turntable 31 also rotates 90 degrees counterclockwise, so that the already loaded limiting tube 73 enters the heat treatment station b, and the new water bucket 8 also enters the heat treatment station b. During the rotation of the rotary table 6, the rotating bevel gear 42 meshes with the fixed bevel gear 41, causing the rotating bevel gear 42 to rotate. Since the number of teeth of the rotating bevel gear 42 is half the number of teeth of the fixed bevel gear 41, when the rotary table 6 rotates 90 degrees, the rotating bevel gear 42 meshes with the bevel gear with half its own number of teeth. Therefore, the support shaft 71 rotates 180 degrees. That is, when the rotary table 6 rotates 90 degrees, the support shaft 71 rotates 180 degrees, which means that the limiting tube 73 changes from an upward upright state to a downward upright state.

[0051] At this point, the ring-shaped part slides from the end near the base 72 along the limiting tube 73 to the end away from the base 72 until it encounters the support member 742 and stops sliding down. The support member 742 plays a supporting and limiting role for the ring-shaped part, preventing the ring-shaped part from sliding down.

[0052] Hydraulic cylinder 33 is activated, causing lifting plate 2 to rise. Heating induction coil 10 moves upward along with fixed plate 9. Limiting slide 16 restricts the rotation of fixed plate 9. Fixed plate 9 is rotatably connected to lifting plate 2, ensuring that fixed plate 9 remains stationary while lifting plate 2 rotates, guaranteeing that heating induction coil 10 and water supply pipe 11 are always aligned with the corresponding water bucket 8. Water bucket 8 moves upward with lifting plate 2. Initially, heating induction coil 10 is not energized. When lifting plate 2 reaches a certain height, and heating induction coil 10 is at the same height as the bottom ring-shaped part, heating induction coil 10 is energized to heat the ring-shaped part. While heating, it slowly rises, heating multiple parts on limiting pipe 73 in sequence. Since water bucket 8 also rises, the heated parts slowly immerse themselves below the water surface in water bucket 8, thus cooling the heated parts.

[0053] After heat treatment is completed, the heating induction coil 10 is de-energized, the lifting plate 2 descends, and the parts are removed from the water tank 8. When the water tank 8 descends to its bottom and is placed in the circular groove 311 of the turntable 31, the drive motor 51 starts again, driving the rotating table 6 and the turntable 31 to rotate 90 degrees. The new parts enter the heat treatment station b, while the heat-treated parts enter the drying station c. The limit tube 73 rotates 180 degrees again, changing to an upright position, and the dryer 13 dries the water stains on the surface of the parts.

[0054] Meanwhile, the new water bucket 8 enters the heat treatment station b as the turntable 31 rotates. During the 90-degree rotation of the used water bucket 8, the universal ball 123 contacts and slides with the lifting block 125. As the height of the lifting block 125 increases during this 90-degree process, it eventually reaches its highest point at 90 degrees. Therefore, the push rod 122 can move upward. The baffle 121, which was originally located in the circular groove 81, was blocking the drain hole 82. When the baffle 121 rises under the action of the push rod 122, the baffle 121 no longer blocks the drain hole 82, and the water bucket 8 begins to drain. The drained water flows into the water collection tank 32 and finally enters the factory's cooling tower from the drain outlet 322 for cooling and reuse.

[0055] As the rotary table 6 and turntable 31 continue to rotate 90 degrees counterclockwise, the dried parts enter the unloading station d. The limiting tube 73 is once again in an upright downward position. At this time, the limiting motor 741 reverses, causing the support 742 to retract into the limiting tube 73, allowing the parts on the limiting tube 73 to slide off and fall into the temporary storage box 15 through the unloading slide 14. Thus, the heat treatment cycle for one part is completed. The water tank 8, which was originally drained of cooling water, also rotates 90 degrees. As the lifting block 125 begins to decrease in height during this process, the spring 124 releases pressure, forcing the baffle 121 to descend and re-block the drain hole 82. When the water tank 8 enters below the water supply pipe 11, the water supply pipe 11 can refill the water tank 8 with new cooling water for the next use.

[0056] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
