Description

Technical Field

[0001] The present invention relates to the field of heat treatment technology, in particular to a heat treatment device for metal part processing. Background Art

[0002] Heat treatment refers to a metal thermal processing process in which the chemical composition and structure of the surface or interior of a material are changed by heating, heat preservation and cooling in a solid state to obtain the desired properties. High-frequency quenching of metal pipes is a localized hardening process for the surface of metal pipes (such as steel pipes and alloy pipes). By combining high-frequency induction heating with rapid cooling, a high-hardness martensite structure is formed on the pipe surface while maintaining the toughness of the core. This process is widely used in fields such as petroleum, machinery, and automobiles where pipes require high wear resistance and fatigue resistance. Existing metal tubes undergoing high-frequency hardening often use a vertical structure. After the tubes are heated, spraying them generates a large amount of water vapor. Due to gravity, the spray water on vertical tubes is distributed more at the bottom and less at the top: The lower portion has ample water, resulting in rapid cooling; the upper portion has less water, where steam tends to accumulate and form a continuous "steam film." This steam film significantly hinders heat exchange between the upper tube and the cooling water, ultimately resulting in uneven circumferential and axial hardness distribution, making the tube unsuitable for use. Moreover, when unloading, manual handling is required. If the material is not cooled below the appropriate temperature, the workers may be easily burned, making it difficult to ensure the safety of unloading. Summary of the Invention

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-8 , a heat treatment device for metal part processing, including a table 1, with legs 2 arranged at the four corners below the table 1, and further including: During actual use, the legs 2 provide stable support for the table 1. On the table 1, there are a heat treatment component for high-frequency quenching of metal pipes, a carrying component for carrying metal pipes, a moving component for driving the carrying component to move, and a steam collection component for collecting steam. In this embodiment, the heat treatment component includes a partition 3, a liquid supply component, an annular pipe 4, an output head 5, a high-frequency quenching machine 6, and a coil 7. The liquid supply component, the partition 3, and the coil 7 are sequentially arranged on the table 1. An annular pipe 4 is arranged at one end of the partition 3 close to the liquid supply component. Several groups of output heads 5 are arranged inside the annular pipe 4. A high-frequency quenching machine 6 is arranged below the table 1. The two free ends of the coil 7 penetrate through the table 1 and are connected to the high-frequency quenching machine 6. The output end of the liquid supply component is connected to the input end of the annular pipe 4. The carrying component includes a fixing plate 8, a connecting beam 9, a first turntable 10, a second turntable 11, a moving plate 12, a feeding component, and a third motor 13. The connecting beam 9 is in a downward-opening U shape. Two groups of the connecting beams 9 are arranged on both sides of the partition 3. Two groups of the fixing plates 8 are arranged on the front and rear sides of the partition 3. The free ends below the connecting beam 9 are connected to the fixing plate 8. A first turntable 10 is arranged on the fixing plate 8 close to the annular pipe 4. A feeding component for driving the moving plate 12 to move is further arranged between the two groups of the fixing plates 8. A second turntable 11 is further arranged at one end of the moving plate 12 close to the first turntable 10. A third motor 13 for driving the second turntable 11 to rotate is arranged on the moving plate 12. A through hole is arranged on the partition 3. Both the second turntable 11 and the first turntable 10 can penetrate through the through hole. The annular pipe 4 is arranged on the periphery of the through hole. A moving component for driving the carrying component to move is further arranged on the table 1. Initially, the moving part drives the carrying assembly to the loading area of ​​the table 1. At this time, the first turntable 10 passes through the partition 3 and the coil 7. Two groups of fixed plates 8 and the connecting beam 9 form a carrying skeleton. One group of fixed plates 8 stably supports the first turntable 10. Initially, the distance between the first turntable 10 and the second turntable 11 is large. The metal pipe is placed between the first turntable 10 and the second turntable 11. The feeding part is started, and the moving plate 12 drives the second turntable 11 to move toward the first turntable 10, clamping the metal pipe between the first turntable 10 and the second turntable 11. In this embodiment, the main bodies of the first turntable 10 and the second turntable 11 are 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 1000 MPa below 600°C and a hardness of HRC30-35, which is sufficient to withstand the clamping pressure and rotational friction of the metal pipe (especially thick-walled pipe). More importantly, its magnetic permeability is close to 1 (weakly magnetic), which does not interfere with the alternating magnetic field generated by the high-frequency coil 7, thus preventing uneven heating of the metal tube due to magnetic field distortion. To further enhance wear resistance and insulation, a layer of zirconium oxide (ZrO2) ceramic coating (0.15-0.2mm thick) is sprayed on the surface of the turntable that contacts the metal tube. Zirconia ceramic is not only heat-resistant (melting point exceeds 2700°C), which can withstand the residual heat of the metal tube, but also has a Rockwell hardness of up to HRA88 and wear resistance 5-8 times that of pure metal, effectively reducing surface wear caused by long-term clamping. At the same time, the ceramic's insulating properties (resistivity >10¹) are excellent. 4 Ω・cm) can completely block the current conduction between the turntable and the metal tube, avoiding additional eddy current loss during high-frequency induction. At this time, the first turntable 10 passes through the partition 3 and the coil 7; The high-frequency quenching machine 6 and the coil 7 cooperate to heat the metal tube, mainly based on the principle of electromagnetic induction. The high-frequency quenching machine 6 generates high-frequency current, and the coil 7 converts the current into an alternating magnetic field, thereby heating the metal tube. The inner diameter of the coil 7 is larger than the outer diameter of the metal tube. As the movable part drives the bearing assembly to move toward the partition 3, the coil 7 heats the metal tube. After the metal tube passes through the coil 7, the metal tube in the alternating magnetic field generates eddy currents on its surface due to electromagnetic induction. Due to the skin effect, the current is mainly concentrated on the surface of the metal tube, causing the surface of the metal tube to heat up rapidly. The heat generated by the eddy current causes the surface temperature of the metal tube to rise rapidly, and it can rise to 800-1000℃ within a few seconds, while the core of the metal tube is still close to room temperature at this time, until the second turntable 11 passes through the coil 7, the partition 3 and the annular tube 4, and the heated metal tube is sprayed to cool down, and then the feed part is started, which drives the movable plate 12 to move, and the distance between the first turntable 10 and the second turntable 11 becomes larger, and the metal tube is unloaded; The third motor 13 is started, and the third motor 13 drives the second rotating disk 11 to rotate, thereby driving the metal tube to rotate, ensuring that the metal tube is evenly heated; The metal tube passes through the partition 3, the liquid supply component is started, and the output head 5 of the annular tube 4 sprays the rotating metal tube to ensure that the metal tube is evenly cooled. At this time, a large amount of water vapor will be generated, and the steam collection component is started. The partition 3 is also provided with a steam collection component for collecting steam. The steam collection component absorbs the steam, and the partition 3 blocks the water vapor.

Another group of fixed plates 8 stably supports the cover 15. The first motor 14 is started. The first motor 14 drives the worm 17 in the cover 15 to rotate. The worm 17 drives the two groups of worm gears 16 to rotate. The worm gear 16 then drives the first screw 18 to rotate.
