Description

Technical Field

[0001] The present invention relates to the technical field of toughening treatment of metal materials, and in particular to a device and method for toughening treatment of metal materials. Background Art

[0002] The metal heating furnace in the existing metal material toughening treatment device has some significant shortcomings, which restricts the improvement of the toughening treatment effect of metal materials. First of all, the traditional metal heating furnace usually adopts a static heating method, that is, the metal material is fixed in the heating furnace for heating. This heating method lacks a rotation function and cannot achieve uniform heating of the metal material during the heating process, which leads to uneven heating and affects the toughening effect of the metal material. In addition, the design of the existing heating furnace is usually unable to achieve local high-temperature heating during the overall heating process. For metal materials that require specific local areas to reach higher temperatures, this causes inaccurate temperature control during the heating process and cannot meet some special toughening requirements.

[0003] The temperature control system of traditional metal heating furnaces is relatively simple and difficult to flexibly adjust to the different heating requirements of different metal materials, which often leads to low thermal efficiency. Due to the large differences in the composition, structure and physical properties of metal materials, a single heating method cannot optimize the treatment of different materials. In addition, the heating rate of existing equipment and the temperature fluctuation during the heating process are large, and it is impossible to achieve fast and stable temperature control, which affects the stability and efficiency of the toughening process.

[0004] Therefore, how to provide a metal material toughening treatment device and method is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0016] Further, the usage steps are as follows:

[0017] Step 1: Put the metal to be processed into the heating furnace, cover it with a flip cover, start the distributed optical fiber sensor to detect the thermal distribution inside the metal to be processed, and simulate the data when local high-temperature heating is performed during heating; establish a mathematical model of the metal heating process in the control software, and build a numerical simulation model of the metal heating process based on thermodynamic principles and the thermal conductivity characteristics of the metal, such as a finite element analysis (FEA) model. The model should be able to reflect the thermal response and temperature changes of the metal under different heating conditions; thereby predicting the changes in the physical properties of the metal in different time periods and at different temperatures, so that when processing the metal, there is reference data, and the heating state of the heating furnace is controlled by relying on the data value. This simulated data value is used as a preliminary reference data value;

[0018] Step 2: The positive and negative electric rails are used as power sources, and the size of the power sources is controlled. The positive and negative electric rails are connected to the positive and negative electric slides, and the electric heating wire is energized through the conductor. The electric heating wire heats the heating furnace and gradually increases the temperature in the heating furnace.

[0019] Step 3: When the heating furnace is heated uniformly, the rotating motor is started. The rotation of the rotating motor drives the rotation of the rotating main gear. The rotation of the rotating main gear drives the rotation of the rotating auxiliary gear, the transmission rod and the transmission gear. The transmission gear is meshed with the transmission gear set. The rotation of the transmission gear drives the rotation of the transmission gear set and the sliding ring. The rotation of the sliding ring drives the electric heating wire to rotate around the central axis of the heating furnace to uniformly heat the inside of the heating furnace. The steering motor is started. The rotation of the steering motor drives the steering wheel to turn. The rotation of the steering wheel drives the metal to rotate. The rotation speed of the metal matches the rotation speed of the sliding ring, so that the temperature in the heating furnace is uniform.

[0020] Step 4: When the metal is locally heated at high temperature, on the basis of uniform heating in the heating furnace, the temperature of the electric heating wire corresponding to the local position of the metal is increased, and the circulating air pump is started. The circulating air pump allows the hot gas inside the heating furnace to enter the gas supply main pipe and the gas supply branch pipe through the exhaust pipe, and the hot gas then enters the gas box ring and the gas box slip ring. The air control valve is opened, and the hot gas flows out at high speed through the extended gas pipe and the U-shaped gas pipe. The opening of the U-shaped gas pipe matches the electric heating wire with increased temperature. The hot fluid carries the electric heating wire with increased temperature to the local position of the metal at high speed, so that the temperature of the local position of the metal is increased;

[0021] Step 5: During the local high-temperature heating of the metal, the internal temperature of the heating furnace is increased. The temperature sensor in the heating furnace is used to detect the internal overall temperature of the heating furnace. When the internal overall temperature of the heating furnace is increased, the vacuum pump is started. The vacuum pump extracts outside air through the first air inlet pipe and the air filter column, and then injects the air into the heating furnace through the second air inlet pipe. The hot air from the heating furnace flows out of the air exhaust pipe through the open air valve to maintain the internal overall temperature of the heating furnace, thereby preventing the local high-temperature heating of the metal from affecting the internal overall temperature of the heating furnace.

[0022] Step 6. During the metal processing process, the preliminary reference data value in step 1 is used as a reference, and real-time detection is performed through distributed optical fiber sensors and temperature sensors. The real-time temperature distribution data is input into the heating model, and the model is simulated for heating and the data parameters of the heating temperature are adjusted first to control the temperature of the metal during local high-temperature heating.

[0023] The beneficial effects of the present invention are:

[0024] The present invention achieves uniform heating in a heating furnace by rotating an electric heating wire, thereby reducing the temperature gradient between the interior and surface of the metal; when the metal is heated unevenly, internal stress is easily accumulated due to inconsistent expansion and contraction of different parts; the uniformity of the metal's grain structure is improved, and the temperature distribution is uneven. The grains inside the metal may present an uneven structure due to the heating rate and temperature differences in different areas, resulting in differences in the performance of the metal; the rotating heating unit can accurately control the rate during the heating process, avoid local overheating or overcooling, ensure that the heating and cooling processes are smoother and more uniform, and help the metal obtain a uniform organizational structure, thereby better improving toughness.

[0025] The present invention has the function of locally heating the metal. The metal is locally heated at high temperature during the overall heating process to achieve differentiation of the performance of different areas of the metal, thereby achieving the purpose of comprehensively improving the performance of the metal. The application of local high-temperature heating in a metal heating furnace can effectively improve the toughness, hardness and wear resistance of the metal. By precisely controlling the heating area and temperature, the performance of the metal parts can be optimized, and the wear resistance and hardness at the execution end can be enhanced, while maintaining high toughness in the toughness area. Local heating can reduce thermal deformation, internal stress and energy consumption, and improve the service life and work efficiency of the metal parts. Local high-temperature heating can accurately control the balance between hardness and toughness according to the specific needs of the metal parts during use. By improving the hardness and wear resistance at the execution end, it is ensured that the metal can resist external impact and wear, while maintaining high toughness in the toughness area of ​​the metal to avoid brittle fracture. The metal parts can show excellent performance under different working conditions. Local high-temperature heating enables the performance of each metal part to be customized according to specific needs. This flexibility is particularly suitable for metal parts with complex shapes and demanding application scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Furthermore, the steering motor 5.2 rotates to drive the steering wheel 5.3, and the rotation of the steering wheel 5.3 drives the metal to rotate. The rotation speed of the metal matches the rotation speed of the sliding ring 8, so that the temperature in the heating furnace 1 is uniform.

[0053] The present invention provides a metal material toughening treatment device, and the steps of using the device are as follows:

[0054] Step 1: Put the metal to be processed into the heating furnace 1, cover it with the flip cover 3, start the distributed optical fiber sensor 17 to detect the thermal distribution inside the metal to be processed, and simulate the data when local high-temperature heating is performed during heating; establish a mathematical model of the metal heating process in the control software, and build a numerical simulation model of the metal heating process based on the thermodynamic principles and the thermal conductivity characteristics of the metal, such as a finite element analysis (FEA) model. The model should be able to reflect the thermal response and temperature changes of the metal under different heating conditions; thereby predicting the changes in the physical properties of the metal in different time periods and at different temperatures, so that when processing the metal, there is reference data, and the heating state of the heating furnace 1 is controlled by relying on the data value. The simulated data value is used as a preliminary reference data value;

[0055] Step 2: The positive electric rail 11 and the negative electric rail 12 are used as power sources, and the size of the power sources is controlled. The positive electric rail 11 and the negative electric rail 12 are connected to the positive electric slide plate 13 and the negative electric slide plate 14, and the electric heating wire 16 is energized through the conductor 15. The electric heating wire 16 heats the heating furnace 1 and gradually increases the temperature in the heating furnace 1;

[0056] Step 3: When the heating furnace 1 is heated uniformly, the rotating motor 9.1 is started. The rotation of the rotating motor 9.1 drives the rotation of the rotating main gear 9.2. The rotation of the rotating main gear 9.2 drives the rotation of the rotating auxiliary gear 9.3, the transmission rod 9.4 and the transmission gear 9.5. The transmission gear 9.5 is meshed with the transmission gear set 9.6. The rotation of the transmission gear 9.5 drives the rotation of the transmission gear set 9.6 and the sliding ring 8. The rotation of the sliding ring 8 drives the electric heating wire 16 to rotate around the central axis of the heating furnace 1 to uniformly heat the inside of the heating furnace 1. The steering motor 5.2 is started. The rotation of the steering motor 5.2 drives the steering wheel 5.3 to rotate. The rotation of the steering wheel 5.3 drives the metal to rotate. The rotation speed of the metal matches the rotation speed of the sliding ring 8, so that the temperature in the heating furnace 1 is uniform.

[0057] Step 4: When the metal is locally heated at high temperature, on the basis of uniform heating in the heating furnace 1, the temperature of the electric heating wire 16 corresponding to the local position of the metal is increased, and the circulating air pump 6.1 is started. The circulating air pump 6.1 allows the hot gas inside the heating furnace 1 to enter the gas supply main pipe 6.3 and the gas supply branch pipe 6.4 through the exhaust pipe 6.2, and the hot gas then enters the gas box ring 10.1 and the gas box slip ring 10.2. The air control valve 10.4 is opened, and the hot gas flows out at a high speed through the extended gas pipe 10.3 and the U-shaped gas pipe 10.5. The opening of the U-shaped gas pipe 10.5 matches the electric heating wire 16 with increased temperature. The hot fluid carries the electric heating wire 16 with increased temperature to flow to the local position of the metal at a high speed, so that the temperature of the metal at the position is increased;

[0058] Step 5: During the local high-temperature heating of the metal, the internal temperature of the heating furnace 1 is increased. The temperature sensor in the heating furnace 1 detects the internal overall temperature of the heating furnace 1. When the internal overall temperature of the heating furnace 1 is increased, the air extraction pump 6.5 is started. The air extraction pump 6.5 extracts outside air through the first air inlet pipe 6.6 and the air filter column 6.7, and then injects the air into the heating furnace 1 through the second air inlet pipe 6.8. The hot air from the heating furnace 1 flows out of the air exhaust pipe 6.9 through the open air valve 6.10 to maintain the internal overall temperature of the heating furnace 1, so as to avoid the local high-temperature heating of the metal affecting the internal overall temperature of the heating furnace 1.

[0059] Step 6. During the metal processing process, the preliminary reference data value in step 1 is used as a reference, and real-time detection is performed through the distributed optical fiber sensor 17 and the temperature sensor. The real-time temperature distribution data is input into the heating model, and the model is simulated for heating and the data parameters of the heating temperature are adjusted first to control the temperature during local high-temperature heating of the metal.

[0060] The present invention rotates the electric heating wire 16 to evenly heat the heating furnace 1, thereby reducing the temperature gradient between the inside and the surface of the metal. In the traditional heating process, if the heating is uneven, some areas of the metal may produce stress concentration due to overheating, or the plastic behavior of the material cannot be fully stimulated due to low temperature. This uneven heating will cause thermal stress and strain inside the metal, which will further affect the toughness of the metal and the stability of the overall structure; by rotating the electric heating wire 16, the metal can be exposed to different heat source positions during the heating process, so that the heat distribution is more uniform, avoiding local overheating or overcooling, and reducing the adverse effects of temperature differences on metal properties.

[0061] When metal is heated unevenly, due to inconsistent expansion and contraction of different parts, internal stress is likely to accumulate; if these internal stresses are not effectively released, it may cause brittle fracture or deformation of the metal during subsequent use; the rotating electric heating wire 16 can promote uniform thermal expansion of the metal, making the overall expansion and contraction of the metal more coordinated, thereby effectively reducing the generation of internal stress and improving the toughness of the metal.

[0062] Improve the uniformity of the metal's grain structure. During the heating process, if the temperature distribution is uneven, the grains inside the metal may present an uneven structure due to the heating rate and temperature differences in different areas, resulting in differences in the metal's performance. Larger grains tend to reduce the toughness of the metal because the grain boundaries are weak areas for crack propagation. By rotating the heating unit, the metal can be heated to the same degree at different angles and areas, which helps the uniform growth and distribution of the grains, thereby improving the overall toughness of the metal.

[0063] The control of heating rate and cooling rate directly affects the toughness of the metal; too fast heating or cooling rate may cause a large temperature difference between the metal surface and the interior, thereby causing cracks and internal stress; the rotating electric heating wire 16 can accurately control the rate during the heating process, avoid local overheating or overcooling, ensure that the heating and cooling process is more stable and uniform, and help the metal obtain a uniform organizational structure.

[0064] The present invention has the function of locally heating the metal, which requires advance simulation of step one to achieve heating of different areas, achieve differentiation of performance of different areas of the metal, and achieve the purpose of comprehensively improving the performance of the metal; the application of local high-temperature heating in the metal heating furnace 1 can effectively improve the toughness, hardness and wear resistance of the metal; by precisely controlling the heating area and temperature, the performance of the metal parts can be optimized, and the wear resistance and hardness at the execution end can be enhanced, while maintaining high toughness in the toughness area; local heating can reduce thermal deformation, internal stress and energy consumption, and improve the service life and work efficiency of the metal parts; local high-temperature heating can accurately control the balance between hardness and toughness according to the specific needs of the metal parts during use; at the execution end, by improving the hardness and wear resistance, it is ensured that the metal can resist external impact and wear, while maintaining high toughness in the toughness area of ​​the metal to avoid brittle fracture; metal parts can show excellent performance under different working conditions; local high-temperature heating enables the performance of each metal part to be customized according to specific needs; this flexibility is particularly suitable for metal parts with complex shapes and demanding application scenarios.
