In the bearing assembly, the first rotating disc and the second rotating disc are matched with the third motor to drive the metal pipe to rotate, so that the pipe body is uniformly contacted with the output heads of the annular pipe in the circumferential direction; meanwhile, the multiple groups of output heads on the inner side of the annular pipe can uniformly spray the cooling medium from the circumferential direction, so that the water distribution problem of the vertical structure that there is more water at the lower part and less water at the upper part is avoided. The combination of rotation and circumferential spraying can effectively break the steam film, ensure the uniformity of the cooling speed in the axial direction and the circumferential direction of the pipe body, and thus ensure the uniformity of the hardened layer and the stability of the hardness; the steam collection assembly can quickly suck away the steam generated during quenching through the air suction cover, the air suction pipe and the fan below the top plate, and the retention of the steam on the surface of the pipe body is reduced.

Description

Technical Field

[0001] This invention relates to the field of heat treatment technology, specifically to a heat treatment apparatus for metal parts processing. Background Technology

[0002] Heat treatment refers to a metal heat treatment process in which the chemical composition and structure of a material are changed on or inside the material by means of heating, holding and cooling in the solid state, so as to obtain the desired properties.

[0003] High-frequency quenching of metal pipes is a local hardening process for the surface of metal pipes (such as steel pipes, alloy pipes, etc.). By combining high-frequency induction heating with rapid cooling, a high-hardness martensitic structure is formed on the surface of the pipe body, while maintaining the toughness of the core. It is widely used in petroleum, machinery, automobile and other fields where the wear resistance and fatigue resistance of pipelines are required.

[0004] Existing metal tubes often employ a vertical structure during high-frequency quenching. After the metal tube is heated, spraying generates a large amount of water vapor. Due to gravity, the distribution of sprayed water on the tube surface exhibits a "more at the bottom, less at the top" characteristic: the lower part has ample water and a rapid cooling rate; the upper part has less water, and steam easily accumulates to form a continuous "vapor film." This vapor film significantly hinders heat exchange between the upper part of the tube and the cooling water, ultimately resulting in uneven hardness distribution around the circumference and along the axis of the tube, failing to meet usage requirements.

[0005] Furthermore, manual handling is required during material feeding. If the material is not cooled to a suitable temperature, workers may be burned, making it difficult to guarantee the safety of material feeding. Summary of the Invention

[0016] The output end of the second motor passes through the bracket and is connected to the second screw. The second screw is rotatably connected to the crossbeam, and both sides of the crossbeam are connected to the top wall of the connecting beam.

[0018] Preferably, the liquid supply assembly includes a liquid supply tank, a liquid supply pump, a connecting pipe, and an inlet pipe. The liquid supply tank is also provided on the platform.

[0024] (III) Beneficial Effects

[0025] Compared with the prior art, the present invention provides a heat treatment apparatus for metal parts processing, which has the following beneficial effects:

[0026] In this heat treatment apparatus for metal parts processing, the supporting components include a first and second turntable that, in conjunction with a third motor, drive the metal tube to rotate, ensuring uniform circumferential contact between the tube and the output head of the annular tube. Simultaneously, multiple output heads inside the annular tube spray cooling medium evenly from the circumference, avoiding the "more at the bottom, less at the top" water distribution problem found in vertical structures. This combination of rotation and circumferential spraying effectively breaks up the vapor film, ensuring consistent cooling rates in both the axial and circumferential directions, thereby guaranteeing the uniformity and hardness stability of the hardened layer.

[0027] The steam collection assembly, through the suction hood, suction pipe, and fan below the top plate, can quickly remove the steam generated during quenching, reducing steam retention on the tube surface. This not only avoids the obstruction of heat exchange by the steam film, but also reduces the degree of oxidation on the tube surface, reduces oxide scale formation, improves surface smoothness, and improves the workshop working environment.

[0028] The moving parts can automatically switch the load-bearing components between heating, cooling, and unloading stations, reducing manual intervention; the load-bearing components (sloping plate, buffer pad) in the waste liquid collection tank can receive the processed metal pipes, the drainage holes of the sloping plate facilitate the separation of waste liquid, the buffer pad prevents the workpiece from being bumped, and there is no need for manual handling of high-temperature workpieces, which fundamentally reduces the risk of workers being burned.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please refer to Figure 1- Figure 8 A heat treatment apparatus for processing metal parts includes a table 1, with support legs 2 provided at the four corners below the table 1, and further includes:

[0040] In actual use, the support leg 2 provides stable support for the platform 1. The platform 1 is equipped with a heat treatment component for high-frequency quenching of metal pipes, a support component that can support metal pipes, a moving part that can drive the support component to move, and a steam collection component for collecting steam.

[0041] In this embodiment, the heat treatment assembly includes a partition 3, a liquid supply assembly, an annular tube 4, an output head 5, a high-frequency quenching machine 6, and a coil 7. The liquid supply assembly, the partition 3, and the coil 7 are sequentially arranged on the platform 1. An annular tube 4 is arranged near one end of the partition 3 close to the liquid supply assembly. Several sets of output heads 5 are arranged inside the annular tube 4. The high-frequency quenching machine 6 is arranged below the platform 1. The two free ends of the coil 7 pass through the platform 1 and are connected to the high-frequency quenching machine 6. The output end of the liquid supply assembly is connected to the input end of the annular tube 4.

[0042] The load-bearing assembly includes a fixed plate 8, a connecting beam 9, a first turntable 10, a second turntable 11, and a moving...

[0043] The system includes a moving plate 12, a feed component, and a third motor 13. The connecting beam 9 is in the shape of a downward-opening C-shape. Two sets of the connecting beams 9 are arranged on both sides of the partition plate 3. Two sets of the fixed plates 8 are arranged on the front and rear sides of the partition plate 3. The free ends of the connecting beams 9 are connected to the fixed plates 8. A first turntable 10 is arranged on the fixed plate 8 near one end of the annular tube 4. A feed component that drives the moving plate 12 is also arranged between the two sets of fixed plates 8. A second turntable 11 is also arranged on the moving plate 12 near one end of the first turntable 10. A third motor 13 that drives the second turntable 11 to rotate is also arranged on the moving plate 12. A through hole is provided on the partition plate 3. Both the second turntable 11 and the first turntable 10 can pass through the through hole. The annular tube 4 is arranged around the through hole.

[0044] The platform 1 is also provided with a movable component that drives the load-bearing component to move;

[0045] Initially, the moving component drives the bearing assembly in the loading area of ​​the table 1. At this time, the first turntable 10 passes through the partition 3 and the coil 7. The two sets of fixed plates 8 and the connecting beam 9 form the bearing frame. One set of fixed plates 8 stably supports the first turntable 10. Initially, the distance between the first turntable 10 and the second turntable 11 is relatively large. The metal tube is placed between the first turntable 10 and the second turntable 11. The feeding component is started, and the moving plate 12 drives the second turntable 11 to move towards the first turntable 10, clamping the metal tube between the first turntable 10 and the second turntable 11. In this embodiment, the main body of the first turntable 10 and the second turntable 11 is made of GH3030 nickel-based high-temperature alloy. This alloy is mainly composed of nickel and chromium. It can still maintain a tensile strength of more than 1000MPa below 600℃ and a hardness of HRC30-35, which is sufficient to withstand the clamping pressure and rotational friction of the metal tube (especially the thick-walled tube). More importantly, its permeability is close to 1 (weak magnetism), which will not interfere with the alternating magnetic field generated by the high-frequency coil 7, avoiding uneven heating of the metal tube due to magnetic field distortion. To further improve wear resistance and insulation, a layer of zirconia (ZrO2) ceramic coating (thickness 0.15-0.2mm) is sprayed on the surface of the turntable in contact with the metal tube. Zirconia ceramic is not only resistant to high temperatures (melting point over 2700℃) and can withstand the residual heat baking of the metal tube, but its Rockwell hardness is as high as HRA88, and its wear resistance is 5-8 times that of pure metal, which can effectively reduce surface wear caused by long-term clamping; at the same time, the insulating properties of ceramic (resistivity > 10¹⁴ Ω·cm) can completely block the current conduction between the turntable and the metal tube, avoiding additional eddy current losses during high-frequency induction. At this time, the first turntable 10 passes through the partition 3 and the coil 7.

[0046] The high-frequency quenching machine 6, in conjunction with coil 7, heats the metal tube primarily based on the principle of electromagnetic induction. The high-frequency quenching machine 6 generates a high-frequency current, which coil 7 converts into an alternating magnetic field, thus heating the metal tube. The inner diameter of coil 7 is larger than the outer diameter of the metal tube. As the moving component drives the supporting assembly towards the partition 3, coil 7 heats the metal tube. When the metal tube passes through coil 7, eddy currents are generated on its surface due to electromagnetic induction while it is in the alternating magnetic field. Due to the skin effect, the current is mainly concentrated on the surface of the metal tube, causing it to heat up rapidly. The heat generated by the eddy currents causes the surface temperature of the metal tube to rise rapidly, reaching 800-1000℃ within seconds, while the core of the metal tube remains close to room temperature. This continues until the second turntable 11 passes through coil 7, partition 3, and annular tube 4. The heated metal tube is then sprayed to cool it down. Then, the feed component is activated, driving the moving plate 12 to move, increasing the distance between the first turntable 10 and the second turntable 11, and the metal tube is unloaded.

[0047] Start the third motor 13, which drives the second turntable 11 to rotate, thereby driving the metal tube to rotate and ensuring that the metal tube is heated evenly.

[0048] The metal tube passes through the baffle 3, and the liquid supply component is activated. The output head 5 of the annular pipe 4 sprays water onto the rotating metal tube to ensure uniform cooling of the metal tube. At this time, a large amount of water vapor is generated, and the steam collection component is activated. The baffle 3 is also equipped with a steam collection component for collecting steam. The steam collection component absorbs the steam, and the baffle 3 blocks the water vapor.

[0049] In actual use, the feeding component includes a first motor 14, a cover 15, a worm gear 16, a worm 17, and a first screw 18. A cover 15 is also provided on a fixed plate 8 away from the first turntable 10. The cover 15 contains a worm 17 and two sets of worm gears 16. The output end of the first motor 14 passes through the cover 15 and is connected to the worm 17. Two sets of first screws 18 are rotatably arranged between the two sets of fixed plates 8. A partition 3 is disposed between the two sets of first screws 18. The first screw 18 passes through the fixed plate 8 and the cover 15 and is centrally connected to the worm gear 16. The moving plate 12 is threadedly connected to the two sets of first screws 18. Another set of fixed plates 8 stably supports the cover 15. When the first motor 14 is started, it drives the worm 17 inside the cover 15 to rotate. The worm 17 drives the two sets of worm gears 16 to rotate. This, in turn, causes the first screw 18 to rotate, and the moving plate 12 drives the second turntable 11.

[0050] Feed, thereby adjusting the distance between the first turntable 10 and the second turntable 11.

[0051] In actual use, the moving component includes a bracket 19, a guide block 20, a guide rail 21, a second motor 22, a second screw 23, and a crossbeam 24. The guide block 20 is provided on the top wall of the connecting beam 9. The bracket 19, which is shaped like a downward-opening C-shape, is provided above the platform 1. The guide rail 21, which is slidably connected to the guide block 20, is also provided below the bracket 19. The second screw 23 is rotatably provided below the top wall of the bracket 19. The output end of the second motor 22 passes through the bracket 19 and is connected to the second screw 23. The second screw 23 is rotatably connected to the crossbeam 24. The two sides of the crossbeam 24 are connected to the top wall of the connecting beam 9. The platform 1 supports the bracket 19, and the top wall of the bracket 19 supports the guide rail 21. The guide block 20, which is slidably connected to the guide rail 21, is also provided on the connecting beam 9. When the second motor 22 is started, it drives the second screw 23 to rotate. The guide block 20 is in the shape of an inverted T. The shape, with the cooperation of guide rail 21 and guide block 20, drives the crossbeam 24 to move linearly, thereby driving the load-bearing components to move.

[0052] In actual use, liquid is output from the output head 5 of the annular pipe 4. The steam collection assembly includes a fan 25, a suction pipe 26, a suction hood 27, a top plate 28, and an auxiliary plate 29. A top plate 28 is also provided above the partition 3 near one end of the annular pipe 4. An auxiliary plate 29 connected to the platform 1 is also provided below the top plate 28. The fan 25 is provided on the top plate 28. The input end of the fan 25 is connected to one end of the suction pipe 26. The suction hood 27 is embedded below the top plate 28. The other end of the suction pipe 26 passes through the top plate 28 and is connected to the suction hood 27. When the fan 25 is started, it creates a negative pressure above the annular pipe 4 through the suction hood 27. The steam generated by cooling is immediately drawn into the suction pipe 26 and discharged. The partition 3 and the auxiliary plate 29 stably support the top plate 28, and the top plate 28 stably supports the fan 25.

[0053] In actual use, the liquid supply assembly includes a liquid supply tank 30, a liquid supply pump 31, a connecting pipe 32, and an inlet pipe 33. The platform 1 is also equipped with a liquid supply tank 30. One end of the liquid supply pump 31 is connected to the liquid supply tank 30, and the other end is connected to the connecting pipe 32. The other end of the connecting pipe 32 passes through the top plate 28 and is connected to the annular pipe 4. The liquid supply tank 30 is also equipped with an inlet pipe 33. The liquid supply pump 31 delivers liquid into the connecting pipe 32, and then it is ejected from the output head 5 of the annular pipe 4.

[0054] Liquid can be added to the supply tank 30 through the inlet pipe 33.

[0055] In this embodiment, a waste liquid collection assembly is also provided on the platform 1. The waste liquid collection assembly includes a waste liquid collection tank 34, a drain pipe 35, and a switch valve 36. The platform 1 is also provided with a waste liquid collection tank 34 with an upper opening. The waste liquid collection tank 34 is also provided with a drain pipe 35. The drain pipe 35 is provided with a switch valve 36. The auxiliary plate 29 is located between the waste liquid collection tank 34 and the supply tank 30. The waste liquid collection tank 34 is also provided with a material loading assembly. The material loading assembly includes an inclined plate 37, auxiliary legs 38, and a buffer pad 39. The four corners of the inclined plate 37 are provided with auxiliary legs 38 that are connected to the bottom wall of the waste liquid collection tank 34. The inclined plate 37 is also provided with a buffer pad 39. The inclined plate 37 and the buffer pad 39 are provided with several sets of drainage holes. The sprayed liquid is sent into the waste liquid collection tank 34. By opening and closing the switch valve 36, the liquid can pass through the drain pipe 35. During the transfer, when the moving component drives the bearing assembly into the unloading area, and the feeding component drives the second turntable 11 to move away from the first turntable 10, the metal tube falls onto the buffer pad 39. The auxiliary leg 38 supports the inclined plate 37, and the inclined plate 37 stably supports the buffer pad 39, facilitating the unloading and transfer of materials.

[0056] In actual use, centering blocks 40 are provided on the adjacent sides of the first turntable 10 and the second turntable 11. Both sets of centering blocks 40 have rounded edges on the adjacent sides to facilitate material unloading and to facilitate centering and supporting the metal pipe during loading. The platform 1 is also equipped with a height adjustment device for supporting materials. This device includes a lifter 41, a lifting plate 42, and a support frame 43. The upper and lower ends of the lifter 41 are connected to the lifting plate 42 and the platform 1, respectively. The lifting plate 42 is also equipped with the support frame 43. The lifter 41 uses a cylinder for rapid response. During loading, the lifter 41 is activated, causing the lifting plate 42 to rise. The support frame 43 supports the metal pipe. It should be noted that the support frame 43 is V-shaped to ensure proper centering and support of the material. After the first turntable 10 and the second turntable 11 have completed the centering and clamping of the material, the lifter 41 moves the lifting plate 42... As the device descends, the top wall of the support frame 43 is lower than the bottom wall of the moving plate 12, and the moving plate 12 will not interfere with the movement of the support frame 43.
