[0033] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further explained in detail below in combination with specific implementation manners and in reference to the drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0034] It is understood that the description is only exemplary and is not intended to limit the scope of the utility model.

[0035] Some embodiments of the utility model provided by the utility model are described below in combination with the drawings to provide a photovoltaic aluminum profile mold nitriding furnace.

[0036] In combination with Figures 1-4 It is shown that the photovoltaic aluminum profile mold nitriding furnace of the utility model comprises a loading frame 100, a nitriding furnace body 200, a cabin rotating frame 300 and a plurality of mold seat cabins 400.

[0037] The loading frame 100 is used for loading and transmission of the mold, and the electromagnet positioner 110 is used for accurate positioning during the loading process. The electromagnet positioner 110 is fixedly installed on the surface of the loading frame 100, and its function is to realize accurate alignment between the mold seat cabin 400 and the loading frame 100 through electromagnetic adsorption and corresponding cooperation of the positioning block 420 on the mold seat cabin 400. When the mold seat cabin 400 is aligned with the loading frame 100, the mold can be smoothly loaded into the mold seat cabin 400 through the loading frame 100. After the loading is completed, the electromagnet positioner 110 releases the adsorption force, and the mold seat cabin 400 automatically enters the nitriding treatment stage.

[0038] The transfer frame 300 comprises a support base 310 and a transfer vane 320 rotatably mounted on one side of the support base 310. A driving motor 330 is fixedly mounted on the support base 310 and used to drive the transfer vane 320 to rotate. A plurality of mold seat cabins 400 are movably mounted between the oppositely arranged transfer vanes 320 and uniformly distributed on the circumferential surface of the transfer vane 320. By driving the transfer vane 320 to rotate by the driving motor 330, the mold seat cabin 400 can be switched between different stations. Each mold seat cabin 400 can independently place a photovoltaic aluminum profile mold, ensuring that multiple molds can be alternately subjected to nitriding treatment, thereby greatly improving production efficiency.

[0039] The mold seat cabin 400 is a core component for placing and nitriding photovoltaic aluminum profile molds. The inner side of the mold seat cabin 400 is provided with a plurality of support mold seats 402 for stably placing photovoltaic aluminum profile molds. The surface of the mold seat cabin 400 is provided with an open slot for loading the mold, and a gate 401 is provided for sealing the open slot. In actual operation, the gate 401 is opened, the photovoltaic aluminum profile mold is loaded into the mold seat cabin 400, and the gate 401 is closed to ensure airtightness. At the same time, the two ends of the mold seat cabin 400 are rotatably connected to the transfer vane 320 through shaft ears 410, ensuring the balance and stability of the mold seat cabin 400 during the transfer process.

[0040] The open slot inside the mold seat cabin 400 can be customized according to different specifications of photovoltaic aluminum profile molds to ensure accurate placement of the molds and avoid displacement of the molds during nitriding. In addition, the inner surface of the mold seat cabin 400 is provided with a high-temperature-resistant and corrosion-resistant coating, and the open slot in the mold seat cabin 400 is customized according to the size of the photovoltaic aluminum profile mold to ensure that molds of different specifications can be accurately placed and achieve the best nitriding effect.

[0041] The nitriding furnace body 200 comprises a PTC heating furnace 210, a conveying air duct 230, a circulating fan 220, and a backflow air duct 240, which are connected in sequence to form a circulating channel for the furnace atmosphere. The circulating fan 220 is of an axial flow fan structure, the PTC heating furnace 210 is used for heating the nitriding gas, and the circulating fan 220 drives the gas flow to circulate in the furnace chamber to ensure the uniformity of the furnace atmosphere. The conveying air duct 230 and the backflow air duct 240 are in communication with the PTC heating furnace 210 and the circulating fan 220, respectively, to form a complete gas flow loop.

[0042] In actual operation, nitrogen enters the inside of the mold seat cabin 400 through the air guide valve 211 and the flange gate 241, and uniformly heats and nitrides the mold surface through the nitrogen circulation system in the mold seat cabin 400. The air guide valve 211 and the flange gate 241 are electromagnetic valve structures, which are automatically opened when the air guide valve 211 and the flange gate 241 are aligned and communicated with the mold seat cabin 400 communication port 403, and are automatically opened when the mold seat cabin 400 is communicated with the nitriding furnace body 200, allowing the gas flow to enter; when the mold seat cabin 400 is separated from the nitriding furnace body 200, the electromagnetic valve is automatically closed to ensure the airtightness of the nitriding furnace body and prevent nitrogen leakage.

[0043] The control system of the present application includes a flow control module, a temperature detection module, an atmosphere monitoring module and a feedback adjustment module. The flow control module is used to adjust the nitrogen flow into the hearth to ensure the stability of the atmosphere during nitriding; the temperature detection module is used to monitor the gas temperature inside the PTC heating furnace 210 and automatically adjust the power output of the heater according to the detection result; the atmosphere monitoring module is used to detect the purity of the atmosphere in the furnace in real time, and once the composition of the atmosphere deviates from the preset value, the feedback adjustment module dynamically adjusts the working state of the circulating fan 220 and the PTC heating furnace 210 according to the flow, temperature and atmosphere data to ensure the stability and consistency of the nitriding process. The feedback adjustment module will automatically adjust the gas flow and the heater power to maintain the best nitriding environment. Through the cooperation of these modules, the temperature and atmosphere of the nitriding furnace can be ensured to be in the best state at all times, thereby improving the quality and uniformity of the nitriding layer.

[0044] During the nitriding process, the circulating fan 220 drives the airflow to enter the mold seat cabin 400 through the delivery air duct 230, and after the nitriding reaction on the mold surface, the airflow returns to the PTC heating furnace 210 through the return air duct 240, and after being heated again, it enters the mold seat cabin 400 again. This atmosphere circulation structure not only ensures the uniformity of the atmosphere, but also improves the efficiency of the nitriding reaction. At the same time, through the real-time monitoring and adjustment of the temperature detection module and the atmosphere monitoring module, the purity and temperature of the nitriding gas can be ensured to be within the range required by the process, avoiding defects in the nitriding layer caused by excessive temperature or impure atmosphere.

[0045] Through the design of the present application, not only the efficient nitriding treatment of the mold is realized, but also the energy consumption and operation complexity are reduced, and the automation and intelligence level of the equipment is improved, which is suitable for high-quality nitriding demand of photovoltaic aluminum profile mold.

[0046] The working principle and use process of the present application are as follows:

[0049] Loading operation:

[0050] The operator places the photovoltaic aluminum profile mold on the loading rack 100, and positions the mold seat cabin 400 with the loading rack through the electromagnet positioner 110. After confirming the accurate positioning, the mold is loaded into the mold seat cabin 400 through the loading rack, and the mold seat cabin is sealed through the gate 401.

[0051] Nitriding treatment:

[0052] The changing cabin impeller 320 rotates the mold seat cabin 400 with the mold to the nitriding station. At this time, the gas guide valve 211 and the flange gate 241 are automatically opened, and the nitrogen gas is pushed by the circulating fan 220, enters the mold seat cabin 400 through the delivery air duct 230, and maintains a high temperature state under the heating of the PTC heater 210, to perform nitriding treatment on the mold. After the gas flow completes nitriding, it returns to the heater through the return air duct 240, and circulates.

[0053] Monitoring and adjustment:

[0054] During the nitriding treatment process, the control system will monitor the atmosphere in the furnace in real time, adjust the nitrogen flow rate and heating temperature, and ensure the stability of the nitriding conditions. The system will automatically adjust the working state of the circulating fan 220 and the heater according to the feedback data, to ensure that the gas temperature and flow rate are within the optimal range.

[0055] Cabin rotation and unloading:

[0056] After the nitriding is completed, the changing cabin impeller 320 rotates to transfer the mold seat cabin 400 that has completed nitriding to the unloading station. At the same time, a new mold seat cabin is rotated to the nitriding station for continuous nitriding treatment. At the unloading station, the operator takes out the mold that has completed nitriding treatment by opening the gate 401.

[0057] Shutdown and maintenance:

[0058] When all the molds are processed, the operator turns off the equipment. The control system will perform a self-check on the state of the nitriding furnace, ensure that the atmosphere in the furnace is completely discharged, and prompt the operator to perform regular maintenance and maintenance operations to ensure the long-term stable operation of the equipment.
