[0002] Metal heat treatment is a process of heating a metal or alloy workpiece to a suitable temperature in a certain medium, keeping it at this temperature for a certain period of time, and then cooling it at different speeds in different media to control its performance by changing the surface or internal microstructure of the metal material. When processing metal materials now, it is necessary to heat treat the material to eliminate the stress inside the material and improve the mechanical properties of the material.

[0003] In the existing metal surface heat treatment device, heat is usually generated through the interaction of the magnetic field after the induction coil is energized, so that the workpiece is heated up. After the temperature reaches a certain temperature, the workpiece is heat treated by spraying water to make it have better surface properties, such as hardness, wear resistance and corrosion resistance. In the process of coolant spraying, due to the performance and processing requirements of the material, the quenching distance and time of the workpiece need to be changed according to the specific situation to adapt to the processing effect required by the performance of different materials. However, in the prior art, the spray angle of the coolant is mostly at the same angle as the workpiece, which cannot be well adapted, so that its adaptability is limited to a certain extent. At the same time, it cannot be effectively adjusted according to the material properties, which may affect the surface heat treatment effect of the workpiece. Summary of the invention

When passing through the second water pipe, the water flow will come into contact with the spiral rod. At this time, the spiral rod is completely immersed in the coolant. The circulation of the coolant will cause the rotation of the spiral rod. At this time, after the spiral rod rotates, it can accelerate the coolant to push backward, thereby increasing the circulation rate of the coolant. After the coolant increases the circulation speed, the power used by the water pump can be reduced, thereby reducing the energy consumption of the water pump and increasing the service life of the water pump. At the same time, accelerating the circulation speed of the coolant can also shorten the exposure time of the workpiece to high temperature, thereby accelerating the entire heat treatment process and improving production efficiency. At the same time, it can reduce the residence time of the workpiece in the furnace, so that more workpieces can complete the heat treatment in a short time, improve the overall throughput of the production line, and improve work efficiency.

The output shaft end of the electric push rod 21 is fixedly connected to one of the second connecting rods 19. An arc-shaped connecting plate 22 is fixedly connected to one side of the quenching ring 12. A limit rod 23 is slidably connected inside the arc-shaped connecting plate 22. A cooling component is arranged on one side of the heat treatment chamber 1, and a transmission component is arranged inside the heat treatment chamber 1. The second connecting rod 19 is pushed to move by the second support plate 20. The movement of the second connecting rod 19 drives the pushing ring 18 to move. The movement of the pushing ring 18 drives the first connecting rod 17 and the semicircular support plate 16 to move. The movement of the semicircular support plate 16 drives the spherical water outlet 14 to rotate downward, thereby synchronously adjusting the water spraying angles of multiple spherical water outlets 14, thereby changing the surface structure and performance of the material according to needs, improving its hardness, strength and toughness, thereby improving the overall mechanical properties, and at the same time improving its adaptability to adapt to a variety of different metal materials.

[0041] Wherein, the cooling assembly includes a first water pipe 5, a water pump 6 is fixedly connected to the top of the first water pipe 5, a first support plate 7 is fixedly sleeved on the outer side of the water pump 6, the first support plate 7 is fixedly connected to one side of the heat treatment chamber 1, a second water pipe 8 is fixedly connected to the upper side of one side of the water pump 6, two first fixed plates 9 are fixedly connected to one side of the inner side of the second water pipe 8, a first rotating shaft 10 is movably sleeved on the opposite side of the two first fixed plates 9, a spiral rod 11 is fixedly sleeved on the outer side of the first rotating shaft 10, and the diameter of the spiral rod 11 is smaller than the diameter of the second water pipe 8. When the water pump 6 is started, the coolant in the cooling box 4 is extracted through the first water pipe 5, and the coolant passes through the second water pipe 8 during the extraction process. When the water flow comes into contact with the screw rod 11, the screw rod 11 is completely immersed in the coolant. The circulation of the coolant will cause the screw rod 11 to rotate. At this time, the screw rod 11 can accelerate the coolant backward after rotating, thereby increasing the circulation rate of the coolant. After the coolant increases the circulation rate, the power used by the water pump 6 can be reduced, thereby reducing the energy consumption of the water pump 6 and increasing the service life of the water pump 6. At the same time, accelerating the circulation rate of the coolant can also shorten the exposure time of the workpiece to high temperature, thereby speeding up the entire heat treatment process and improving production efficiency. At the same time, it can reduce the residence time of the workpiece in the furnace, so that more workpieces can complete the heat treatment in a short time, thereby improving the overall throughput of the production line.

[0042] Wherein, the transmission assembly includes a first drive motor 24, the output end of the first drive motor 24 is fixedly connected with a threaded rod 25, the threaded rod 25 is rotatably connected to the heat treatment chamber 1, the threaded rod 25 is threadedly connected to the outer side of the movable block 26, the movable block 26 is slidably connected to the inside of the heat treatment chamber 1, one side of the movable block 26 is fixedly connected with a mounting plate 27, the top of the mounting plate 27 is fixedly connected with a second drive motor 28, baffles are arranged on both sides of the second drive motor 28, and the two baffles are fixedly connected to the mounting plate 27, the output shaft end of the second drive motor 28 is fixedly connected with a connecting shaft 36, and one end of the connecting shaft 36 is fixedly connected with a first push rod 29, the transmission assembly also includes a first fixed sleeve 30, the first fixed sleeve 30 is fixedly connected to the inside of the cooling box 4, a spring 31 is arranged inside the first fixed sleeve 30, one end of the spring 31 is fixedly connected to the first fixed sleeve 30, a second push rod 32 is slidably connected to the inside of the first fixed sleeve 30, the other end of the spring 31 is fixedly connected to the second push rod 32, the first fixed sleeve 30, the second push rod 32 and the first push rod 2 9 are all on the same axis, the second drive motor 28 is started to drive the first push rod 29 and the first fixed sleeve 30 to rotate, thereby driving the workpiece 33 to rotate, and at the same time, the first drive motor 24 is started to rotate to drive the threaded rod 25 to rotate, and the threaded rod 25 rotates to drive the movable block 26 to make a linear uniform motion along the threaded rod 25, and the movement of the movable block 26 will drive the mounting plate 27 to move, and the movement of the mounting plate 27 drives the second drive motor 28, the connecting shaft 36 and the first push rod 29 to move, thereby giving pressure to the workpiece 33 to drive it to press down, and at the same time, high-voltage alternating current is passed to the induction coil 34. After power is turned on, the induction coil 34 will generate a changing magnetic field, and this changing magnetic field will induce eddy currents in the metal workpiece, and the eddy currents will also generate reverse magnetic fields. The interaction of the two magnetic fields will generate heat, so that the workpiece 33 is rapidly heated, and the heating of the workpiece 33 is completed. The entire heating process is a highly coordinated and precisely controlled operation sequence, which not only requires synchronous movement between various components, but also requires precise energy management to ensure the uniformity and efficiency of the heating effect. In this way, surface heat treatment can improve surface properties such as hardness, wear resistance and corrosion resistance without compromising the structural integrity of the workpiece.

[0043] Among them, a workpiece 33 is abutted between the first push rod 29 and the second push rod 32, a fixed shaft 35 is fixedly connected to one side of the inside of the heat treatment chamber 1, and an induction coil 34 is fixedly connected to one end of the fixed shaft 35. The arc-shaped connecting plate 22 is fixedly connected to the bottom of the fixed shaft 35, and the midpoint of the arc-shaped connecting plate 22 and the workpiece 33 is on the same axis as the first push rod 29. The workpiece 33 is arranged below the arc-shaped connecting plate 22, and the workpiece 33 is driven to rotate by the rotation of the second drive motor 28. Since the midpoint of the arc-shaped connecting plate 22 and the workpiece 33 is arranged on the same axis as the first push rod 29, the workpiece 33 can be better heated after rotation to improve the heat treatment effect of its surface.

[0044] Among them, a sliding groove is provided at the top of the heat treatment chamber 1 corresponding to the second drive motor 28, the first water pipe 5 extends to the inside of the cooling box 4, the length of the first water pipe 5 is shorter than the height of the cooling box 4, and the two sealing rings 15 are both in contact with the spherical surface of the spherical water outlet 14. By providing a sliding groove at the top of the heat treatment chamber 1 corresponding to the second drive motor 28, the second drive motor 28 can have a margin when moving upward to increase its displacement distance, thereby increasing the processing range of the workpiece and improving the processing adaptability. The two sealing rings 15 are in contact with the spherical surface of the spherical water outlet 14, so that the coolant can flow better after entering the spherical water outlet 14 to avoid waste of coolant caused by retention in the second fixed plate 13.

[0045] Working principle:

[0046] The workpiece to be subjected to surface heat treatment is placed against the middle of the first ejector rod 29 and the second ejector rod 32. This step ensures the stability of the workpiece and the precise alignment during the processing. After the placement is completed, the second drive motor 28 is started to drive the first ejector rod 29 and the first fixed sleeve 30 to rotate, thereby driving the workpiece 33 to rotate. At the same time, the first drive motor 24 is started to rotate to drive the threaded rod 25 to rotate. The rotation of the threaded rod 25 drives the movable block 26 to move along the threaded rod 25 at a uniform speed in a straight line. The movement of the movable block 26 will drive the installation plate 27 to move. The movement of the installation plate 27 drives the second drive motor 28 and the connecting shaft 36 The first push rod 29 moves, thereby applying pressure to the workpiece 33 to drive it downward, and at the same time, a high voltage alternating current is supplied to the induction coil 34. After power is supplied, the induction coil 34 will generate a changing magnetic field. This changing magnetic field will induce eddy currents in the metal workpiece, and the eddy currents will also generate a reverse magnetic field. The interaction of the two magnetic fields will generate heat, causing the workpiece 33 to heat up rapidly, completing the heating of the workpiece 33. The entire heating process is a highly coordinated and precisely controlled operation sequence, which requires not only synchronous movement between the various components, but also precise energy management to ensure the uniformity and efficiency of the heating effect. In this way, surface heat treatment can improve its surface properties, such as hardness, wear resistance, and corrosion resistance, without compromising the structural integrity of the workpiece.

[0047] After the workpiece 33 is heated to the required surface heat treatment temperature, the first push rod 29 pushes the workpiece 33 to slowly approach the quenching ring 12. At this time, the water pump 6 starts to extract the coolant in the cooling box 4 through the first water pipe 5. The coolant will pass through the second water pipe 8 during the extraction process. When passing through the second water pipe 8, the water flow will contact the screw rod 11. At this time, the screw rod 11 is completely immersed in the coolant. The circulation of the coolant will cause the screw rod 11 to rotate. At this time, the screw rod 11 can accelerate the coolant backward after rotating, thereby increasing the circulation rate of the coolant. After the coolant increases the circulation rate, the power used by the water pump 6 can be reduced, thereby reducing the energy consumption of the water pump 6 and increasing the service life of the water pump 6. At the same time, accelerating the circulation rate of the coolant can also shorten the exposure time of the workpiece to high temperature, thereby accelerating the entire heat treatment process and improving production efficiency. At the same time, it can reduce the residence time of the workpiece in the furnace, so that more workpieces can complete the heat treatment in a short time, thereby improving the overall throughput of the production line;

[0048] The coolant flows into the quenching ring 12 through the second water pipe 8, and the coolant quickly fills the inside of the quenching ring 12. At this time, the coolant flows into the interior of the multiple spherical water outlets 14 and then sprays out through the spherical water outlets 14, thereby quickly cooling the workpiece 33. If the material properties of the workpiece 33 change, the second support plate 20 starts to push the second connecting rod 19 to move, and the movement of the second connecting rod 19 drives the pushing ring 18 to move, and the movement of the pushing ring 18 drives the first connecting rod 17 and the semicircular support plate 16 to move, and the movement of the semicircular support plate 16 drives the spherical water outlet 14 to rotate downward, thereby synchronously adjusting the water spraying angles of the multiple spherical water outlets 14, thereby changing the surface structure and properties of the material as needed, improving its hardness, strength and toughness, thereby improving the overall mechanical properties, and at the same time improving its adaptability to adaptability. With a variety of different metal materials, the workpiece 33 continues to move and will enter the interior of the cooling box 4 and contact the coolant inside the cooling box 4, so that the heating position can be completely immersed in the coolant and subjected to secondary cooling, so as to further adjust and optimize the material structure, thereby improving its mechanical properties, such as hardness, strength and toughness. At the same time, secondary cooling can reduce or eliminate the internal stress caused by rapid cooling, and avoid deformation or cracking of the workpiece during use. At the same time, after cooling the workpiece, the coolant will fall back into the interior of the cooling box 4 due to gravity to complete the recycling of the coolant and avoid waste of the coolant. Moreover, because the coolant undergoes a series of movements, the contact area between the coolant and the air is accelerated, and the cooling of the coolant itself is accelerated, thereby avoiding the overall cooling rate of the coolant being too high and enhancing the cooling capacity.
