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 furnaces in existing metal material toughening treatment devices have some significant deficiencies, which restrict the improvement of the toughening treatment effect of metal materials. First of all, traditional metal heating furnaces usually adopt 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, resulting in uneven heating, which in turn affects the toughening effect of the metal material. In addition, the design of existing heating furnaces 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] Traditional metal heating furnaces feature a relatively simple temperature control system, making it difficult to flexibly adjust to the varying heating requirements of different metal materials, often resulting in low thermal efficiency. Due to the wide variations in composition, structure, and physical properties of metal materials, a single heating method cannot optimize the treatment of different materials. Furthermore, existing equipment experiences significant heating rates and temperature fluctuations during the heating process, making rapid and stable temperature control impossible, impacting the stability and efficiency of the toughening process.

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

[0017] Step 1: Place the metal to be processed into the heating furnace and close the cover. First, activate the distributed fiber optic sensor to detect the thermal distribution inside the metal to be processed and simulate the data when performing local high-temperature heating during heating. By establishing a mathematical model of the metal heating process in the control software, based on thermodynamic principles and the thermal conductivity characteristics of the metal, a numerical simulation model of the metal heating process is constructed, such as a finite element analysis (FEA) model. This 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 at different time periods and temperatures. This provides reference data when processing the metal, and the data values are used to control the heating state of the heating furnace. The simulated data values serve as preliminary reference data values.

[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 wires are energized through the conductors. The electric heating wires heat the heating furnace and gradually increase the temperature inside the heating furnace.

[0019] Step 3: When the heating furnace is uniformly heated, 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 engaged 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, thereby uniformly heating the interior of the heating furnace. The steering motor is started. The rotation of the steering motor drives the steering wheel to rotate. 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, thereby making the temperature in the heating furnace uniform.

[0020] Step 4: When heating the metal locally 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 draws the hot gas inside the heating furnace into 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, thereby increasing the temperature of the local position of the metal;

[0021] Step 5: During the local high-temperature heating of the metal, the internal temperature of the heating furnace is increased. The overall internal temperature of the heating furnace is detected by the temperature sensor in the heating furnace. When the overall internal temperature of the heating furnace increases, the air extraction pump is started. The air extraction pump draws 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 opened air valve to maintain the overall temperature of the heating furnace, thereby preventing the local high-temperature heating of the metal from affecting the 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 fiber optic 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 heating temperature data parameters are adjusted first to control the temperature during local high-temperature heating of the metal.

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

[0024] The present invention rotates the electric heating wire to uniformly heat the heating furnace, thereby reducing the temperature gradient between the interior and surface of the metal; when the metal is heated unevenly, the inconsistent expansion and contraction of different parts can easily lead to the accumulation of internal stress; 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 metal's performance; 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, so as to achieve differentiation of the 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 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 their 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

[0056] Step 3: When heating the heating furnace 1 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, thereby uniformly heating the interior 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 locally heating the metal 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 increases, and the circulating air pump 6.1 is started. The circulating air pump 6.1 conveys the hot gas inside the heating furnace 1 through the exhaust pipe 6.2 into the gas supply main pipe 6.3 and the gas supply branch pipe 6.4. 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 high speed through the gas extension pipe 10.3 and the U-shaped gas pipe 10.5. The opening of the U-shaped gas pipe 10.5 matches the increased temperature of the electric heating wire 16. The hot fluid carries the increased temperature of the electric heating wire 16 to the local position of the metal at high speed, causing the local temperature of the metal to increase;

[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 inside the heating furnace 1 detects the overall internal temperature of the heating furnace 1. When the overall internal temperature of the heating furnace 1 increases, the air extraction pump 6.5 is started. The air extraction pump 6.5 draws 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 opened air valve 6.10, thereby maintaining the overall temperature of the heating furnace 1 and preventing the local high-temperature heating of the metal from affecting the overall internal 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 temperature distribution data is input into the heating model through distributed optical fiber sensor 17 and temperature sensor. The model is simulated for heating and the heating temperature data parameters are adjusted first to control the temperature of the metal during local high-temperature heating.

[0060] The present invention uniformly heats the interior of the heating furnace 1 by rotating the electric heating wire 16, thereby reducing the temperature gradient between the interior and surface of the metal. In conventional heating processes, if the heating is uneven, certain areas of the metal may experience stress concentration due to overheating, or the material's plastic behavior may not be fully stimulated due to low temperatures. This uneven heating can cause thermal stress and strain within the metal, which in turn affects the metal's toughness and overall structural stability. By rotating the electric heating wire 16, the metal can be exposed to different heat source locations during the heating process, resulting in more uniform heat distribution, avoiding local overheating or overcooling, and reducing the adverse effects of temperature differences on metal properties.

[0061] When metal is heated unevenly, internal stresses can easily accumulate due to inconsistent expansion and contraction of different parts. If these internal stresses are not effectively released, the metal may suffer brittle fracture or deformation 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 to uniformly grow and distribute 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 surface and the interior of the metal, 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 smoother and more uniform, and help the metal obtain a uniform microstructure.

[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 their 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; 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.
