DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-5 The present application provides a technical scheme:

[0024] Please refer to Figures 1-5 As shown in the figure, an aluminum material heat treatment device with gas protection, the bottom plate 1 is provided with a conveying assembly and an aluminum plate blanking assembly above, the conveying assembly includes a belt 11, the belt 11 is fixedly connected with a conveying box 7, the aluminum plate blanking assembly includes a mounting frame 5 mounted on the bottom plate 1 above;

[0025] The mounting frame 5 is located at one end of the horizontal plane of the bottom plate 1, and an aluminum plate placing rack 6 is mounted above the mounting frame 5. A threaded rod 8 and a limiting rod 9 are mounted on one side of the aluminum plate placing rack 6 close to the end of the bottom plate 1. The threaded rod 8 is threadedly connected with the aluminum plate placing rack 6, and the bottom of the threaded rod 8 is rotationally connected with the mounting frame 5. A motor one 13 is mounted on the bottom surface of the mounting frame 5 and is drivingly connected with the threaded rod 8. A limiting block 10 is mounted on one side of the conveying box 7 close to the threaded rod 8. A slot 20 matching the limiting block 10 is formed in the mounting frame 5. The limiting block 10 is attached to the inner wall of the slot 20. An aluminum plate passing groove 21 passing through the slot 20 is formed in the aluminum plate placing rack 6 close to the opening of the slot 20. The limiting block 10 can slide horizontally in the slot 20 and the aluminum plate passing groove 21.

[0026] In the specific implementation process, when the material needs to be discharged, the motor one 13 is started to drive the threaded rod 8 to rotate, so that the aluminum plate placing rack 6 descends along the threaded rod 8. Due to the presence of the limiting rod 9, the aluminum plate placing rack 6 remains stable during the descending process. When the aluminum plate placing rack 6 descends to a certain height (i.e., the bottom of the aluminum plate is flush with or slightly lower than the top of the conveying box 7), the aluminum plates stacked on the aluminum plate placing rack 6 can be moved by the movement of the limiting block 10. Due to the presence of the aluminum plate passing groove 21, and the fact that the top of the aluminum plate passing groove 21 is in a closed state, when the limiting block 10 passes through the slot 20, only the bottommost aluminum plate will be moved. The bottommost aluminum plate passes through the aluminum plate passing groove 21 and finally slides onto the conveying box 7.

[0027] The limiting block 10 plays a guiding and limiting role, ensuring that the aluminum plate can smoothly and accurately enter the conveying box 7. When the aluminum plate slides through the aluminum plate passing groove 21 and falls onto the conveying box 7, the conveying box 7 continues to move forward with the belt 11, carrying the aluminum plate away from the discharging area.

[0028] It should be noted that the mounting frame 5 is stably mounted at one end of the bottom plate 1. The bottom surface of the mounting frame 5 is provided with a motor box one 15, which provides support for the motor one 13. The mounting frame 5 provides support for the aluminum plate placing rack 6. The aluminum plate placing rack 6 is located above the mounting frame 5 and is used to place the stacked aluminum plates to be heat treated.

[0029] Referring to Figures 1-5 The aluminum material heat treatment device with gas protection is provided with side frames 2 on both sides of the bottom plate 1 away from the belt 11. The upper surfaces of the two side frames 2 are provided with sliding seats 3. The sliding seats 3 are provided with sliding grooves 4. The bottom surface of the conveying box 7 is provided with sliding blocks 19 matching the sliding grooves 4.

[0030] In the specific implementation process, the side frame 2 provides a stable mounting base for the sliding seat 3, and ensures the stability and rigidity of the entire conveying assembly. The sliding seat 3 is the track for the sliding block 19 to slide, which is firmly mounted on the side frame 2 through bolts to ensure that no displacement occurs during conveying. The design of the sliding groove 4 enables the sliding block 19 to smoothly slide horizontally, thereby driving the conveying box 7 to move in the specified direction. When the belt 11 drives the conveying box 7 to move, the sliding block 19 slides in the sliding groove 4, providing additional support and guidance for the conveying box 7.

[0031] Referring to Figures 1-5 As shown in the figure, an aluminum material heat treatment device with gas protection, the belt 11 is made of stainless steel material, and the two ends of the belt 11 are drivingly connected with the belt pulley one 17 and the belt pulley two 18. One of the side frames 2 is installed near one side of the mounting frame 5, and the motor box two 16 is installed inside the motor box two 16. The motor two 14 is drivingly connected with the motor two 14.

[0032] In the specific implementation process, the belt 11 is made of stainless steel material, which has good corrosion resistance and high temperature resistance, and can maintain stable performance in the high temperature environment of the heat treatment device. At the same time, the strength and hardness of stainless steel are also high, which can withstand large tension and load, ensuring the smooth and reliable conveying process. The belt 11 is drivingly connected with the belt pulley one 17 and the belt pulley two 18, which can transmit the power generated by the motor two 14 to the belt 11 through the belt pulley one 17, drive the belt 11 to move, and drive the conveying box 7 and the aluminum material on it to move along the predetermined path.

[0033] It should be noted that the belt pulley one 17 and the belt pulley two 18 are key components in the transmission system, which are installed on the side frame 2 through bearings. The motor box two 16 protects the motor two 14 from the influence of dust, water vapor and other external environments.

[0034] Referring to Figures 1-5 As shown in the figure, an aluminum material heat treatment device with gas protection, the bottom plate 1 is installed away from one side of the mounting frame 5, and the heat treatment bin 12 is installed above the side frame 2. The heat treatment bin 12 is installed on the inner surface of the heat treatment bin 12, and the nitrogen injection valve 23 is installed on the top of the inner surface of the heat treatment bin 12. The heat treatment bin 12 is provided with a sliding groove on the two sides away from the heating block 22, and the bin door 24 is installed in the sliding groove.

[0035] In the specific implementation process, the heat treatment bin 12 is installed on the side of the bottom plate 1 away from the mounting frame 5 and above the side frame 2, and this layout ensures that the heat treatment bin 12 can cover and surround the conveyed aluminum material to perform heat treatment in a closed space. The heating blocks 22 installed on both sides of the inner surface of the heat treatment bin 12 are the heat source for heat treatment, and the aluminum material is heated and treated by the heat generated by the heating blocks 22. The nitrogen injection valve 23 installed inside the heat treatment bin 12 is part of the gas protection system and is used to inject nitrogen into the heat treatment bin to isolate oxygen and other harmful gases in the air to prevent the aluminum material from oxidizing or other chemical reactions at high temperatures.

[0036] It should be noted that the nitrogen injection valve 23 is a key gas protection component in the heat treatment device, which is connected to the nitrogen source through the pipeline outside the heat treatment bin 12 and can inject nitrogen into the heat treatment bin 12 when needed.

[0037] It should be noted that the main function of the bin door 24 is to seal the heat treatment bin 12 to prevent heat loss and gas leakage. During the heat treatment process, the bin door 24 remains closed to ensure that the temperature and gas environment inside the heat treatment bin 12 meet the process requirements. When loading or unloading the aluminum material, the bin door 24 can be opened to allow the aluminum material to smoothly enter and exit the heat treatment bin 12. At this time, the gas protection system should be in a closed state to prevent gas leakage.

[0038] Referring to Figures 1-5 The two bin doors 24 have a connecting strip 25 connected at the top, and the heat treatment bin 12 is provided with a hydraulic rod 26 at the top, and the movable end of the hydraulic rod 26 is fixedly connected with the connecting strip 25.

[0039] In the specific implementation process, when the hydraulic rod 26 receives a control signal, the liquid inside the hydraulic rod 26 will be compressed or released, thereby generating a pushing force or a pulling force. In this heat treatment device, the hydraulic rod 26 is fixedly connected with the connecting strip 25 through the movable end thereof. When the hydraulic rod 26 is elongated, it will push the connecting strip 25 and the bin door 24 to move downward, thereby closing the bin door 24. When the hydraulic rod 26 is shortened, it will pull the connecting strip 25 and the bin door 24 to move upward, thereby opening the bin door 24.

[0040] Referring to Figures 1-5 The bottom plate 1 is provided with a supporting leg 27, the mounting frame 5 is provided with a PLC controller above, and the output end of the PLC controller is electrically connected with the input ends of the motor one 13, the motor two 14, the hydraulic rod 26, the heating blocks 22 and the nitrogen injection valve 23.

[0041] In the implementation process, the supporting legs 27 are installed below the bottom plate 1 and serve to support the entire heat treatment device, which ensures that the device can be stably placed on the ground and prevents movement or tilting due to vibration or external forces during the heat treatment process. The PLC controller serves as the control center of the entire heat treatment device and is responsible for receiving input signals, processing logical operations, and outputting control signals.

[0042] It should be noted that the output end of the PLC controller is electrically connected to the input ends of the motor one 13, the motor two 14, the hydraulic rod 26, the heating block 22, and the nitrogen injection valve 23, which means that the PLC controller can directly control the start, stop, and running state of these components. Through programming and setting, the PLC controller can automatically adjust and control the working state of each component according to the preset process parameters and heat treatment process, thereby realizing accurate heat treatment of aluminum materials.

[0043] It should be noted that according to the control signals output by the PLC controller, the motor one 13 and the motor two 14 can start, stop, or change the speed. These signals are transmitted to the motor one 13 and the motor two 14 through the driving circuit to control their running state. The PLC controller controls the electromagnetic valve or proportional valve of the hydraulic system to control the extension and retraction of the hydraulic rod 26. The hydraulic rod 26 executes the action of opening or closing the heat treatment door 24 according to the received signals. The PLC controller controls the on-off or adjusts the heating power of the heating element to control the temperature of the heating block 22. The heating block 22 heats the aluminum materials in the heat treatment chamber 12 according to the received signals. The PLC controller controls the opening and closing of the nitrogen injection valve 23 and the opening of the flow regulating valve to control the amount and speed of nitrogen injection. The nitrogen injection valve 23 injects an appropriate amount of nitrogen into the heat treatment chamber 12 according to the received signals to protect the aluminum materials from oxidation.

[0044] Working principle:

[0045] Step one: When the material needs to be unloaded, the PLC controller sends a signal to start the motor one 13, which drives the threaded rod 8 to rotate. Since the threaded rod 8 is threadedly connected to the aluminum plate placing rack 6, the aluminum plate placing rack 6 will descend along the threaded rod 8. In the descending process, the limiting rod 9 serves as a guide and support to ensure that the aluminum plate placing rack 6 descends smoothly. When the aluminum plate placing rack 6 descends to a certain height (i.e., the bottom of the aluminum plate is flush or slightly lower than the top of the conveying box 7), the limiting block 10 passes through the slot 20 and the aluminum plate through slot 21 with the movement of the conveying box 7, pushing the bottommost aluminum plate to move forward and make it slide onto the conveying box 7. After the motor two 14 is started, the stainless steel belt 11 is moved through the belt pulley one 17 and the belt pulley two 18. With the movement of the belt 11, the conveying box 7 and the aluminum materials on it move forward along the predetermined path and enter the heat treatment chamber 12.

[0046] Step two: after the aluminum material enters the heat treatment bin 12, the heating block 22 starts to work, generating heat to heat the aluminum material. The PLC controller controls the on-off of the heating element or adjusts the heating power to realize accurate control of the temperature of the heating block 22. During the heat treatment process, the nitrogen injection valve 23 injects nitrogen into the heat treatment bin 12 according to the signal of the PLC controller. The nitrogen effectively isolates the oxygen and other harmful gases in the air, preventing the aluminum material from oxidizing or other chemical reactions at high temperatures.

[0047] Step three: before the heat treatment starts, the hydraulic rod 26 is elongated to push the connecting strip 25 and the bin door 24 to move downward, closing the bin door 24 to ensure the sealing of the heat treatment bin 12. After the heat treatment is completed or when the aluminum material needs to be loaded / unloaded, the hydraulic rod 26 is shortened to pull the connecting strip 25 and the bin door 24 to move upward, opening the bin door 24.
