Description

Technical Field

[0001] This utility model relates to the technical field of heat treatment equipment, and in particular to a heat treatment device for improving the electrical conductivity of alloy castings. Background Technology

[0002] In the field of aluminum alloy casting manufacturing, improving the electrical conductivity of aluminum alloy castings is of great significance for optimizing product performance. Heat treatment equipment, as a key device for achieving this goal, is widely used in many industrial production scenarios, such as machinery manufacturing and electronic equipment manufacturing. Its main function is to improve the internal microstructure of the alloy casting by applying specific heat treatment processes, thereby increasing the electrical conductivity of the alloy casting. Currently, the following key technologies are typically required for the practical application of such heat treatment equipment:

[0003] 1. Precise temperature control technology ensures that the temperature can be accurately reached and maintained at the set value during the heat treatment process to meet the heat treatment requirements of different alloy castings.

[0004] 2. Highly efficient heating technology ensures uniform heat distribution within the furnace, preventing localized overheating or underheating of the alloy castings.

[0005] 3. Stable casting load-bearing and positioning technology ensures that the alloy casting remains in a fixed position during heat treatment, preventing shaking from affecting the treatment effect.

[0006] 4. Intelligent parameter setting and monitoring technology allows operators to easily set processing parameters according to the characteristics of different alloy castings and monitor the heat treatment process in real time.

[0007] Currently, there are various heat treatment devices available on the market for improving the electrical conductivity of alloy castings. Some devices use traditional heating methods, such as resistance wire heating, paired with a simple support platform to hold the alloy castings. To accommodate alloy castings of different sizes, some devices are equipped with grating plates.

[0008] However, existing devices have a prominent problem in actual use: the bolted fixing method used to replace the grating plates is time-consuming and complicated. During the heat treatment experiment on conductivity, different models of products need to be processed at different temperatures and for different durations to obtain the most ideal heating data. The inconvenient method of replacing the grating plates means that the grating plates need to be replaced frequently to adapt to castings of different sizes and models during the experiment, which consumes a lot of time, slows down the overall experimental progress, and affects the efficiency of obtaining heating data. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a heat treatment device for improving the electrical conductivity of alloy castings. It solves the problems of existing devices where replacing grating plates using bolted assemblies is time-consuming and complex. Furthermore, in the heat treatment experiment phase for electrical conductivity, different models of products require different temperatures and durations of processing to obtain the most ideal heating data. The inconvenient method of replacing grating plates necessitates frequent replacements during the experimental phase to adapt to castings of different sizes and models, which consumes a significant amount of time, slows down the overall experimental progress, and thus affects the efficiency of obtaining heating data.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A heat treatment apparatus for improving the electrical conductivity of alloy castings includes a heat treatment aging furnace. A support plate is slidably connected inside the heat treatment aging furnace. A partition mechanism for placing alloy castings is provided at the upper end of the support plate. The partition mechanism includes a grid plate disposed at the upper end of the support plate. A limiting and locking mechanism for assembling the grid plate is provided on the outer surface of the support plate. The limiting and locking mechanism includes a U-shaped support, a pin plate, and an externally threaded rod. The U-shaped support is fixedly connected to the outer surface of the support plate. The pin plate is rotatably connected inside the U-shaped support. The externally threaded rod is threaded inside the support plate. A rectangular screw handle is fixedly connected to the outer surface of the externally threaded rod. A rectangular through groove is formed inside the pin plate.

[0027] This application provides a heat treatment device for improving the electrical conductivity of alloy castings. It effectively solves the problems of existing devices where replacing grating plates using bolted assemblies is time-consuming and complex. Furthermore, in the heat treatment experiment phase for electrical conductivity, different models of products need to be processed at different temperatures and for different durations to obtain the most ideal heating data. The inconvenient method of replacing grating plates, requiring frequent replacements to adapt to castings of different sizes and models during the experimental phase, consumes a significant amount of time, slows down the overall experimental progress, and affects the efficiency of obtaining heating data. When dealing with alloy castings of different sizes, a device that adapts to the dimensions of the alloy casting can be selected. The grating plate has multiple rectangular grids inside, which are used to place the alloy castings. These grids block and limit a group of alloy castings, ensuring their stability during heat treatment and preventing accumulation caused by shaking, which could affect the stability of their electrical conductivity after heat treatment. When changing grating plates of different sizes, the limiting position of the pin plate is released by screwing on the external threaded rod. At this time, screwing on the pin plate cancels the assembly of the support plate and the grating plate, allowing for quick disassembly and replacement of the grating plate. In actual production or experiments, when it is necessary to frequently process alloy castings of different sizes, it can quickly respond to changes in casting size, thereby improving work efficiency.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application effectively solves the problem that in existing devices, the bolt assembly fixing method is often time-consuming and complex when replacing the grating plate. Furthermore, during the heat treatment experiment stage for electrical conductivity, different models of products need to be processed at different temperatures and for different durations to obtain the most ideal heating data. The inconvenient method of replacing the grating plate, requiring frequent replacement to adapt to castings of different sizes and models during the experiment stage, consumes a lot of time, slows down the overall experimental progress, and affects the efficiency of obtaining heating data. The overall idea is as follows: A heat treatment device for improving the electrical conductivity of alloy castings, including heat treatment aging... Furnace 1, a heat treatment aging furnace, has a sliding support plate 2 inside. The upper end of the support plate 2 is equipped with a partition mechanism for placing alloy castings. The partition mechanism includes a grating plate 3, which is positioned on the upper end of the support plate 2. The outer surface of the support plate 2 is equipped with a limiting and locking mechanism for assembling the grating plate 3. This limiting and locking mechanism includes a U-shaped support 4, a pin plate 5, and an external threaded rod 6. The U-shaped support 4 is fixedly connected to the outer surface of the support plate 2, the pin plate 5 is rotatably connected inside the U-shaped support 4, and the external threaded rod 6 is threaded into the inside of the support plate 2. A rectangular screw handle 7 is fixedly connected to the outer surface of the external threaded rod 6. When dealing with alloy castings of different sizes, a grating appropriate to the size of the alloy casting can be selected for installation. Plate 3, the grating plate 3 has multiple rectangular grids inside for placing the alloy casting body 12. These rectangular grids obstruct and limit a group of alloy castings, ensuring their stability during heat treatment and preventing accumulation due to shaking, which could affect the stability of their electrical conductivity after heat treatment. When replacing grating plates 3 of different sizes, the limiting position on the pin plate 5 is released by screwing on the external threaded rod 6. At this time, screwing on the pin plate 5 cancels the assembly of the support plate 2 and the grating plate 3, allowing for quick disassembly and replacement of the grating plate 3. When disassembling the support plate 2 and the grating plate 3, hold the rectangular screw handle 7 and rotate it 90 degrees. The rectangular screw handle 7 drives the external threaded rod 6 to rotate. The external threaded rod 6 is threaded inside the bearing plate 2. As the external threaded rod 6 rotates, the rectangular screw handle 7 will move outward, loosening the clamping of the pin plate 5. With its 90-degree rotation, the rectangular screw handle 7 will be parallel to the rectangular through groove 8. The rectangular through groove 8 and the rectangular screw handle 7 are size-matched. At this time, the pin plate 5 can be screwed out from inside the grid plate 3. After the pin plates 5 inserted on both sides of the grid plate 3 are screwed off, the grid plate 3 is in a free state. At this time, different sizes of grid plates 3 can be replaced according to the shape of the alloy casting body 12 of different sizes. The assembly of the bearing plate 2 and the grid plate 3 can be completed by reversing the above process.

[0030] A rectangular through slot 8 is provided inside the pin plate 5. The rectangular through slot 8 is adapted to the rectangular screw handle 7. The external threaded rod 6 is set inside the rectangular through slot 8. A set of sliding limit blocks 9 are fixedly connected inside the heat treatment aging furnace 1. The bearing plate 2 is slidably connected to the inner surface of the set of sliding limit blocks 9. A round rod handle 11 is fixedly connected to the outer surface of the bearing plate 2. A set of alloy casting bodies 12 are provided at the upper end of the bearing plate 2. The set of alloy casting bodies 12 are all ZL101A aluminum alloy castings. The set of alloy casting bodies 12 is placed on the upper end of the bearing plate 2. By holding the round rod handle 11, the bearing plate 2 is inserted into the sliding limit block 9. The sliding limit block 9 limits the placement position of the bearing plate 2. After the alloy casting bodies 12 are placed into the heat treatment aging furnace 1, the screw handle is screwed in. The hinged sealing door 14 inside the furnace 1 seals and shields the internal space of the heat treatment aging furnace 1. When the alloy casting is heat treated in the heat treatment aging furnace 1, the resistance wire inside the heat treatment aging furnace 1 generates heat as a heating element, raising the furnace temperature to the set high temperature. Under this high temperature environment, the atoms inside the alloy gain enough energy to begin active migration, lattice defects are repaired, dislocations move and redistribute, and supersaturated solid solutions gradually decompose, precipitating dispersed strengthening phases. These changes in microstructure eliminate the residual stress generated in the alloy casting during the casting process, optimize the microstructure of the alloy, thereby improving the regularity of the alloy atomic arrangement and the smoothness of the electron conduction channels, and ultimately improving the electrical conductivity of the alloy casting.

[0031] A set of alloy casting bodies 12 are all set inside the grating plate 3. A hinge seat 13 is fixedly connected to the outer surface of the heat treatment aging furnace 1. A sealing door plate 14 is hinged inside the hinge seat 13. Four lifting rings 15 are threadedly connected to the upper end of the heat treatment aging furnace 1. A control box 16 is fixedly connected to the side of the outer surface of the heat treatment aging furnace 1 away from the hinge seat 13. The control box 16 is installed on one side of the heat treatment aging furnace 1. The control box 16 contains a set of control buttons for controlling the start and stop of the heating element of the heat treatment aging furnace 1 and a time relay for controlling the start time of the heating element. Before heat treatment, an optimal set of heat treatment process parameters is determined through orthogonal experiments. When heat treating the alloy casting body 12, the heating time and heat treatment temperature are set based on the experimental data, thereby controlling the heating temperature of the heat treatment aging furnace 1 to be between 180 and 220 degrees Celsius and the holding time to be between four and eight hours. By using the above heat treatment parameters, the electrical conductivity of the ZL101A aluminum alloy casting can be stably controlled without specifically controlling the chemical composition. A control element is installed inside the control box 16. During heat treatment, a built-in temperature sensor monitors the temperature inside the heat treatment aging furnace 1 in real time. The sensor converts the temperature signal into an electrical signal and transmits it to the control box 16. The controller inside the control box 16 compares the received temperature signal with the preset temperature value. If the detected temperature exceeds the set temperature, the controller, depending on the degree of exceedance, can either send an adjustment command to the heating element to automatically adjust its heating power to reduce the current temperature, or, if the temperature exceeds the set temperature significantly, the controller will shut down the equipment and trigger an alarm to alert the operator to handle the situation promptly. This ensures that the heat treatment process is carried out within the set temperature range, guaranteeing the stability of the heat treatment effect and the improvement in electrical conductivity of the alloy casting.

[0032] To address the problems existing in the prior art, this utility model provides a heat treatment device for improving the electrical conductivity of alloy castings. When dealing with alloy castings of different sizes, a grating plate 3 adapted to the size of the alloy casting can be installed. The grating plate 3 has multiple rectangular grids inside for placing the alloy casting body 12. The rectangular grids block and limit a group of alloy castings, thereby ensuring the stability of their state during heat treatment and preventing the alloy castings from accumulating due to shaking, which would affect the stability of their electrical conductivity after heat treatment. When replacing grating plates 3 of different sizes, the limiting position of the pin plate 5 is released by screwing on the external threaded rod 6. At this time, screwing on the pin plate 5 cancels the assembly of the bearing plate 2 and the grating plate 3, and the disassembly and replacement of the grating plate 3 can be completed quickly. In actual production or experimentation, when it is necessary to frequently process alloy castings of different sizes, it can quickly respond to changes in casting size, thereby improving work efficiency.

[0033] Working principle:

[0034] First, a set of alloy casting bodies 12, all made of ZL101A aluminum alloy, are placed on the upper end of the support plate 2. The support plate 2 is then inserted into the sliding limit block 9 by holding the round rod handle 11. The sliding limit block 9 restricts the placement position of the support plate 2. After the alloy casting bodies 12 are placed into the heat treatment aging furnace 1, the hinged sealing door plate 14 inside the heat treatment aging furnace 1 is screwed on. The sealing door plate 14 seals and blocks the internal space of the heat treatment aging furnace 1. When the alloy castings are heat-treated in the heat treatment aging furnace 1, heat is generated by the resistance wire inside the furnace as a heating element. The furnace temperature rises to the set high temperature. Under this high-temperature environment, the atoms inside the alloy gain sufficient energy to begin active migration, lattice defects are repaired, dislocations move and redistribute, and the supersaturated solid solution gradually decomposes, precipitating dispersed strengthening phases. These changes in microstructure eliminate residual stress generated during the casting process, optimize the alloy's microstructure, thereby improving the regularity of the alloy's atomic arrangement and the smoothness of electron conduction channels, ultimately increasing the electrical conductivity of the alloy casting. A control box 16 is installed on one side of the heat treatment aging furnace 1. The control box 16 contains a set of control buttons for controlling the start and stop of the heating elements of the heat treatment aging furnace 1. A time relay that controls the start-up time of the heating element is used to determine an optimal set of heat treatment process parameters through orthogonal experiments before heat treatment. During subsequent heat treatment of the alloy casting body 12, the heating time and heat treatment temperature are set based on the experimental data, thereby controlling the heating temperature of the heat treatment aging furnace 1 between 180 and 220 degrees Celsius and the holding time between four and eight hours. Using these heat treatment parameters, the electrical conductivity of the casting is stably controlled without specifically controlling the chemical composition of the ZL101A aluminum alloy casting. A control element is installed inside the control box 16, and during heat treatment, a built-in temperature sensor... The device monitors the temperature inside the heat treatment aging furnace 1 in real time. The sensor converts the temperature signal into an electrical signal and transmits it to the control box 16. The controller inside the control box 16 compares the received temperature signal with the preset temperature value. If the temperature exceeds the set temperature, the controller can, on the one hand, send an adjustment command to the heating element to automatically adjust its heating power to reduce the current temperature, depending on the degree of exceedance. On the other hand, if the temperature exceeds the set temperature significantly, the controller will shut down the equipment and trigger an alarm to remind the operator to handle the situation in time. This ensures that the heat treatment process is carried out within the set temperature range, guaranteeing the stability of the heat treatment effect and conductivity improvement of the alloy casting.

[0035] The second step involves installing a grating plate 3 that matches the size of the alloy casting when dealing with alloy castings of different sizes. The grating plate 3 contains multiple rectangular grids for placing the alloy casting body 12. These grids obstruct and limit the movement of a group of alloy castings, ensuring stability during heat treatment and preventing accumulation due to shaking, which could affect the stability of the electrical conductivity after heat treatment. When replacing grating plates 3 of different sizes, the limiting position on the pin plate 5 is released by screwing on the external threaded rod 6. Screwing the pin plate 5 then cancels the assembly of the support plate 2 and the grating plate 3, allowing for quick disassembly and replacement of the grating plate 3. When disassembling the support plate 2 and the grating plate 3, hold the rectangular screw handle 7 and rotate it 90 degrees (refer to the instruction manual). Figure 4 (To rotate clockwise) The rectangular screw handle 7 drives the external threaded rod 6 to rotate. The external threaded rod 6 is threaded inside the bearing plate 2. As the external threaded rod 6 rotates, the rectangular screw handle 7 will move outward, loosening the clamping of the pin plate 5. With its 90-degree rotation, the rectangular screw handle 7 will be parallel to the rectangular through groove 8. The rectangular through groove 8 and the rectangular screw handle 7 are size-matched. At this time, the pin plate 5 can be screwed out from inside the grid plate 3. After the pin plates 5 inserted on both sides of the grid plate 3 are screwed off, the grid plate 3 is in a free state. At this time, the grid plate 3 of different sizes can be replaced according to the shape of the alloy casting body 12 of different sizes. The assembly of the bearing plate 2 and the grid plate 3 can be completed by reversing the above process.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
