[0041] The core of this application is to disclose an aging furnace system to improve the automation level of the aging furnace production process.

[0042] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0043] Combination Figures 1-7 , Figure 1 and Figure 2 This is a cross-sectional view. Figure 1 The diagram shows the internal structure of the aging furnace. Figure 2The diagram illustrates the structure of the aging furnace system located below the foundation plane. The aging furnace system disclosed in this application includes an aging furnace, a cooling zone 300, a connecting zone 400, a transport device 200, and a control device. The aging furnace includes a furnace body 100 and a furnace door 110, which is vertically and vertically positioned at the entrance 101 of the furnace body 100 via a lifting device 120. The furnace body 100 contains a heating element 140 and a heat circulation device. The heating element 140 is securely installed inside the furnace body 100 using bolts or other fixing devices. The heat circulation device ensures that the heat from the heating element 140 circulates evenly within the furnace body 100, maintaining a consistent temperature within the furnace. The cooling zone 300 is used for cooling the workpiece, and the connecting zone 400 is used for temporary storage of the workpiece. The transport device 200 includes a transport vehicle, which enables automatic transfer of workpieces between the aging furnace, the cooling zone 300, and the connecting zone 400. Based on the real-time location of the transport vehicle, the control device can automatically control the lifting and lowering of the furnace door 110, enabling the transport vehicle to directly enter and exit the aging furnace. At the same time, the control device can coordinate and control the start-up, shutdown, and operating parameters of the heating element 140 and the thermal circulation device to ensure that the aging process is efficient and stable.

[0044] In actual operation, the workpieces to be processed are first stored in the receiving area 400, and then transferred to the aging furnace by a transport vehicle. The control device automatically opens the furnace door 110 before the transport vehicle enters the aging furnace, and automatically closes the furnace door 110 after the transport vehicle leaves. It then starts the heating element 140 and the thermal circulation device to complete the aging treatment according to preset parameters. After processing, the control device controls the furnace door 110 to open again, and the transport vehicle transfers the workpiece to the cooling area 300 for cooling. The entire process requires no manual intervention, achieving full automation.

[0045] Compared to existing technologies, the aging furnace system disclosed in this application integrates a transport device 200 and a control device, achieving automatic loading and unloading of workpieces and coordinated control throughout the entire process. The control device can automatically open and close the furnace door 110 based on the position of the transport vehicle, avoiding manual operation and improving safety and response speed. The heating element 140 and the heat circulation device are precisely controlled by the control device to ensure uniform temperature distribution within the furnace, improving process consistency and product quality stability. Furthermore, the integrated design of the cooling zone 300 and the connecting zone 400 makes the workpiece handling process more flexible and efficient. Through automation and integration, this application improves the automation level of the aging furnace production process, significantly reduces labor costs, and minimizes human error.

[0046] Furthermore, the control device is equipped with interlocking protection mechanisms for the raising and lowering of the furnace door 110, the starting and stopping of the heating element 140 and the heat circulation device, as well as the entry and exit of the transport vehicle: the transport vehicle is prohibited from moving during the heating process; the heating element 140 and the heat circulation device can only be started when the furnace door 110 is completely closed; the furnace door 110 must be raised to the highest position before the transport vehicle is allowed to enter or exit, thereby ensuring the safety and reliability of each operation link and avoiding equipment failure or safety accidents caused by misoperation.

[0047] The control device can be integrated with a MOM (Manufacturing Operations Management) system to enable intelligent scheduling and production control of the transport device 200. It can also adjust the running path, speed and stopping position of the transport vehicle in real time according to the production plan, so as to realize the automated flow of workpieces and precise matching of production cycle, thereby further improving production efficiency and system synergy.

[0048] The aging furnace is equipped with a heating station, the cooling zone 300 is equipped with a cooling platform station, and the connecting zone 400 is equipped with a loading and unloading station. The transfer of workpieces between the heating station, cooling platform station, and loading / unloading station is completed by a transport vehicle. The control system collects the position information of the workpiece at each station and the processing status of the workpiece in real time, and transmits this information to the MOM system for interaction. After the interaction information is confirmed, the system automatically judges and executes the next operation, including controlling the transport vehicle to perform a series of actions such as loading, transferring, entering the furnace, exiting the furnace, re-transferring, and unloading, thereby realizing the fully automated processing of the workpiece's automatic heating, heat preservation, and cooling. For example, the aging furnace, cooling zone 300, and connecting zone 400 can be arranged side by side, and the heating station, cooling platform station, and loading / unloading station are all equipped with multiple support columns 103. The workpiece is placed on a material tray 104, and the support columns 103 can support the material tray 104. The transport vehicle is used to transfer the material tray 104 and the workpiece.

[0049] In addition, the control device includes a control handle to support manual operation, especially during equipment malfunction repairs or routine maintenance. It allows for flexible switching to manual mode, ensuring convenient operation and safe maintenance. The control device can also integrate an emergency stop switch. This switch is designed to be non-automatic, requiring manual reset to disengage the emergency stop, effectively preventing safety hazards caused by misoperation and ensuring the safety of equipment and personnel.

[0050] The aging furnace system also includes a display screen, which displays the real-time operating status of the aging furnace and transport vehicle, including parameters such as temperature, energy consumption, and time, to achieve visualization and transparency of production process data.

[0051] In some embodiments, the temperature control system of the aging furnace supports both fully automatic and manual operation modes. In fully automatic mode, the heating process is remotely provided by the MOM system, and the aging furnace automatically executes the heating task after receiving the process parameters. During production, real-time data such as the temperature of each temperature control zone in the aging furnace, the process operation stage and time, and equipment power consumption are fed back to the MOM system in real time for easy monitoring and management. In manual operation mode, the operator needs to manually input the process curve and set the heating temperature and time through the industrial control touch screen. After the workpiece enters the furnace body 100 and the furnace door 110 is confirmed to be closed, the operator needs to manually turn on the heating element 140 and the heat circulation device. After the aging furnace enters the normal heating state, it automatically stops heating when the process time is reached, and the furnace door 110 is manually opened by the operator to complete the process.

[0052] Combination Figure 4 The heating element 140 is disposed on the inner wall of the aging furnace. Specifically, the heating element 140 can be suspended from the inner wall of the four horizontal side walls of the aging furnace, including the furnace door 110, by high-alumina ceramic screws. The heating element 140 can be made of 0Cr25Al5 high-resistance alloy strip with a corrugated structure. This material has good high-temperature oxidation resistance, stable resistance characteristics, and good corrosion resistance. The corrugated structure effectively increases the contact area between the heating element 140 and the air, thereby significantly improving the heat exchange efficiency.

[0053] The heat circulation device includes a fan 500, a first air guide plate 510, and a second air guide plate 520. The first air guide plate 510 and the top wall of the aging furnace form a first air duct 111, and the space between the first air guide plate 510 and the bottom wall of the aging furnace forms a furnace chamber 113. The heating station is located inside the furnace chamber 113. The second air guide plate 520 and the side wall of the aging furnace form a second air duct 112. The first air duct 111 and the second air duct 112 are connected. The second air duct 112 is connected to the furnace chamber 113. The fan 500 is mounted on the first air guide plate 510, and the air outlet of the fan 500 is connected to the first air duct 111. The air inlet of the fan 500 is connected to the furnace chamber 113, so that the fan 500 can drive the airflow to circulate between the first air duct 111, the second air duct 112, and the furnace chamber 113, ensuring the uniformity of the temperature inside the aging furnace.

[0054] In this embodiment, the blower 500 can be a centrifugal air-cooled blower. After the blower 500 is started, air is thrown out under the action of centrifugal force and blown towards the heating element 140 in the first air duct 111 and the second air duct 112, carrying away the heat generated therefrom; then, the hot air enters the furnace 113 through the second air duct 112, and then passes evenly through all workpieces through the confluence hole of the lower aluminum alloy wire tray 104, ensuring that the workpieces are fully heated; finally, the air is drawn back into the blower 500 and returns to the first air duct 111, forming a complete hot air circulation loop. The second air guide plate 520 adopts a segmented assembly structure and is suspended on a fixed rod on the inner wall of the furnace 113, which facilitates installation, disassembly and maintenance.

[0055] The aging furnace system disclosed in this application is applicable to aging and annealing processes, such as aluminum wire annealing below 450°C. To ensure accurate temperature control within the furnace, in some embodiments, the furnace body 100 is provided with a flue gas outlet 102, and an exhaust temperature control device is configured at the flue gas outlet 102. This exhaust temperature control device includes an exhaust fan, an exhaust pipe, and an electric regulating valve. The air inlet of the exhaust fan is connected to the flue gas outlet 102 to extract hot gas from the furnace; the air outlet of the exhaust fan is connected to one end of the exhaust pipe, and the other end of the exhaust pipe extends outdoors or to a waste gas treatment system for safe exhaust of waste gas; the electric regulating valve is installed on the exhaust pipe and electrically connected to a control device to dynamically adjust the exhaust flow rate based on real-time temperature feedback within the furnace. The exhaust temperature control device not only improves the uniformity of the furnace temperature but also effectively avoids temperature fluctuations caused by poor or excessively rapid exhaust, thereby ensuring the stability of the aging or annealing process and product quality.

[0056] In other embodiments, in order to achieve rapid exhaust cooling of the aging furnace, combined with Figure 5 The furnace body 100 has a flue gas outlet 102 on its top wall, connecting to the outside and the first air duct 111. A damper device 600 is installed at the flue gas outlet 102, and the outlet of the blower 500 faces the flue gas outlet 102. When the damper device 600 is closed, the blower 500 drives the airflow to circulate between the first air duct 111, the second air duct 112, and the furnace chamber 113. When the damper device 600 is open, the blower 500 drives the airflow towards the flue gas outlet 102, thus enabling the blower 500 to simultaneously drive internal airflow circulation and drive airflow to the outside for heat dissipation. Additionally, air inlets can be installed on the top wall or other side walls of the furnace body 100 to facilitate the exchange of airflow between the furnace body 100 and the outside airflow. An air inlet valve is installed at the air inlet, which opens only when needed to control the airflow in and out. In addition, to ensure the heat preservation effect of the furnace body 100, the door plate of the damper device 600 and the valve plate of the air inlet valve are made of heat-insulating materials with good heat insulation performance, thereby effectively reducing heat loss and improving the overall energy efficiency of the system.

[0057] For example, in combination Figure 5 The damper device 600 includes a mounting frame and two door panels. The mounting frame is located at the smoke exhaust port 102, and the door panels are hinged to the mounting frame. When the damper device 600 is open, the door panels rotate into the first air duct 111. At the same time, an air outlet channel is formed between the two door panels, connecting the smoke exhaust port 102 and the air outlet of the fan 500, ensuring that the airflow can flow directly to the smoke exhaust port 102 along the air outlet channel.

[0058] In some embodiments disclosed in this application, combined with Figure 6 and Figure 7 The lifting device 120 includes a furnace door frame and a hoist. The hoist is mounted on the furnace door frame and connected to the top of the furnace door 110 via a steel wire rope 121. The hoist can drive the furnace door 110 to move up and down between a first position and a second position. The structure is simple and can ensure the stable lifting and lowering of the furnace door 110. When the furnace door 110 is in the first position, the furnace door 110 closes the entrance 101 and forms a closed internal space with the furnace body 100, which can effectively prevent heat leakage and ensure the stability of the furnace temperature, thereby improving the process accuracy and product quality of the aging treatment. When the furnace door 110 is in the second position, the furnace door 110 avoids the entrance 101. At this time, the transport vehicle can enter and exit the furnace body 100 through the entrance 101, realizing linkage control with the transport vehicle without manual intervention, significantly improving the production cycle and automation level.

[0059] Furthermore, combined Figure 6 and Figure 7 The aging furnace system also includes a fall arrestor 130, which comprises a fall arrestor motor 131 and a fall arrestor pin 132. The fall arrestor motor 131 is mounted on the furnace door frame and its operation is controlled by a control device. The fall arrestor pin 132 is connected to the fall arrestor motor 131 in a transmission manner. A positioning sleeve 133 is provided on the furnace door 110. When the furnace door 110 is in the second position, the fall arrestor motor 131 can drive the fall arrestor pin 132 to insert into the positioning sleeve 133 to achieve mechanical locking. This embodiment can effectively prevent the furnace door 110 from falling after the wire rope 121 breaks or the hoist brake fails, thereby significantly improving the safety of equipment operation and avoiding injury to transport vehicles or operators.

[0060] Combination Figure 6 and Figure 7 To improve the stability of the furnace door 110 during lifting and lowering, rollers 114 are symmetrically installed on both sides of the furnace door 110. Simultaneously, the furnace door frame is provided with two vertically extending roller guide grooves. The rollers 114 are respectively embedded in and rotatably positioned within the roller guide grooves to ensure that the furnace door 110 moves smoothly along the extension direction of the roller guide grooves during lifting and lowering. The furnace door frame can be made of 14# channel steel to provide high structural strength and prevent deformation and warping due to long-term use or heavy loads.

[0061] A sealing device is provided at the bottom of the furnace door 110, which adopts an adjustable sealing skirt structure. When the furnace door 110 is in the first position, under its own weight, the skirt can achieve a tight and flexible contact seal with the furnace door 110, effectively preventing heat leakage, thereby significantly improving the heat preservation performance of the furnace body 100 and the stability of the heat treatment process.

[0062] The sealing surface at the bottom of the furnace door 110 can be made of high-temperature and corrosion-resistant materials such as ceramics, tempered glass, or stainless steel to ensure a stable and reliable seal when the furnace door 110 is closed, thereby maintaining a constant temperature inside the furnace. The adjustable sealing skirt can be made of high-temperature resistant rubber or composite materials, which have good adjustability and can adjust the degree of fit with the furnace panel according to actual working conditions, thereby further optimizing the heat preservation effect and energy utilization efficiency of the furnace body 100.

[0063] The transport device 200 can be an AGV (Automated Guided Vehicle) or a three-dimensional material handling system. Taking a three-dimensional material handling system as an example, it includes a vehicle body, a drive unit, a loading rack, a hydraulic lifting device 120, and transport rails. The vehicle body moves along the rails between the aging furnace, the cooling zone 300, and the connecting zone 400 to achieve automatic workpiece transfer. The loading rack is a frame structure installed on the top of the vehicle body; the hydraulic lifting device 120 consists of a movable lifting frame, a hydraulic push cylinder, and a pump station, which can realize the lifting and lowering of the loading rack. In the connecting zone 400, the loading rack is raised to its highest point for loading. After loading the workpiece, the transport vehicle enters the furnace 113. The lifting frame descends, causing the loading rack to fall onto the support column 113 inside the furnace 113, and then the transport vehicle exits. The drive unit adopts a No. 22 channel steel frame structure, with a hydraulic push cylinder, pump station, and drive system at the front end. The walking mechanism is driven by a cycloidal pinwheel reducer through chain transmission, and limit switches and electromagnetic brakes are provided at both ends to prevent overtravel and inertial impact. Power is provided by the take-up machine. The specific structure and operation mechanism of the three-dimensional material cart system and AGV are existing technologies and will not be described in detail in this application.

[0064] In some embodiments, multiple aging furnaces are arranged side by side, and the furnace doors 110 of each aging furnace are of an integral structure, thereby enabling the synchronous opening and closing of multiple furnace doors 110 and improving operational efficiency. For example, Figure 3 The paper illustrates a technical solution that includes two aging furnaces, with the two furnaces sharing the same furnace door 110, which simplifies the operation process and improves the overall consistency of equipment operation.

[0065] Furthermore, the furnace body 100 is divided into multiple heating zones, each equipped with a heating element 140 and a heat circulation device to achieve individual temperature control of each zone, thereby precisely adjusting the temperature at different locations within the furnace and significantly improving furnace temperature uniformity and heat treatment quality.

[0066] The aging furnace system disclosed in this application is also equipped with a safety guardrail, which surrounds the aging furnace, the transport device 200 and the control device to form an effective safety isolation area to ensure the safety of operators.

[0067] The furnace body 100 frame can be welded using 14# and 10# channel steel and angle steel. The outer shell side plates of the furnace body 100 are connected using 3mm thick Q235 steel plates. The overall structure is firm and reliable, not easily deformed, and has a smooth and clean appearance. The furnace top and furnace walls can be formed by stacking prefabricated blocks of all-fiber refractory needle-punched blanket, which can effectively reduce heat loss and improve furnace temperature uniformity and thermal efficiency. For example, the furnace lining fiber thickness is 240mm, and the compressed density is 230kg / m³. The structure is compact, which can prevent gas leakage in the furnace and ensure a stable atmosphere in the furnace. The stacked inlay process makes it less likely to fall off or deform under high temperature conditions. The modular design facilitates partial replacement and reduces maintenance costs.
