[0029] Reference Figures 1 to 3 The utility model proposes an aluminum rod heating furnace, comprising: a heat-resistant plate 1, a heating frame 2, an insulating box body 3, a first baffle 4 and a second baffle 5; six heating channels 11 are evenly penetrated on two opposite sides of the heat-resistant plate 1; the heating frame 2 is sleeved on the heat-resistant plate 1 along the length direction of the heating channel 11; the insulating box body 3 is sleeved on the heating frame 2 along the length direction of the heating channel 11; the first baffle 4 and the second baffle 5 respectively cover the inlet and outlet of the heating channel 11, wherein, when the aluminum rod heating furnace is feeding or discharging, the first baffle 4 and the second baffle 5 are opened to reveal the heating channel 11.

[0030] In the above embodiment, the heat-resistant plate 1 is used as a carrier for the aluminum rods. Six heating channels 11 are evenly arranged in the length direction and penetrate the two surfaces of the heat-resistant plate 1. They are used to place the aluminum rods to be heated, so that multiple aluminum rods can be heated at the same time, greatly improving the production efficiency. The heating channels 11 are set as circular channels. The heat-resistant plate 1 is the main component of the aluminum rod heating furnace and is made of high-temperature resistant materials. It can withstand a long-term high-temperature environment without deformation, damage or deterioration. The heating frame 2 is sleeved around the heat-resistant plate 1 along the length direction of the heating channel 11, and can transfer heat to the four directions of the upper, lower, left and right of the heat-resistant plate 1, ensuring that the heat transferred to the heat-resistant plate 1 during the heating process is highly uniform, effectively avoiding the problem of local overheating or underheating, ensuring the heating quality of the aluminum rods, and thus improving the quality of the final product. The heating frame 2 preferably adopts electric heating, and a heating element such as a resistance wire can be installed inside. Further, the temperature of the heating element can be precisely controlled to achieve rapid and uniform heating of the aluminum rods. The heat-insulating box 3, similar to the way the heating frame 2 is sleeved on the heat-resistant plate 1, covers the outer sides of the heating frame 2 along the length direction of the heating channel 11. The setting of the heat-insulating box 3 effectively reduces the heat loss, thereby improving the heating efficiency and reducing energy consumption, and preventing a large amount of heat from being emitted from the surroundings of the aluminum rod heating furnace to endanger the personal safety of the staff. The heat-insulating box 3 is made of highly efficient heat-insulating and high-temperature resistant materials, which effectively maintains the state inside and outside the heating furnace. The first baffle 4 and the second baffle 5 are respectively arranged at the inlet and outlet of the heating channel 11, which are used to close the heating channel 11 during the heating process to prevent heat loss. They can be opened when feeding or discharging. The opening and closing of the first baffle 4 and the second baffle 5 can be controlled manually or realized by automated equipment to further improve production efficiency. In summary, the aluminum rod heating furnace of this embodiment can achieve efficient and uniform heating of aluminum rods, improve production efficiency, reduce energy consumption, and at the same time ensure the safety and reliability of the heating process.

[0031] In one embodiment, it also includes a first electric cylinder 6 and a second electric cylinder 7, the first electric cylinder 6 is arranged on the inlet side of the heat insulation box 3 close to the heating channel 11, the second electric cylinder 7 is arranged on the outlet side of the heat insulation box 3 close to the heating channel 11, the push rod of the first electric cylinder 6 is fixedly connected to the first baffle 4, and the push rod of the second electric cylinder 7 is fixedly connected to the second baffle 5.

[0032] In the above embodiment, the first electric cylinder 6 and the second electric cylinder 7 are set to control the opening and closing of the first baffle 4 and the second baffle 5, so as to improve the degree of automatic control of feeding and discharging during the heating process of the aluminum rod. The first electric cylinder 6 and the second electric cylinder 7 are respectively arranged on the side of the inlet and outlet of the heat-insulating box 3 close to the heating channel 11. Preferably, the electric cylinder is arranged above the inlet and outlet, that is, above the baffle. Before the aluminum rod heating process begins, the first electric cylinder 6 and the second electric cylinder 7 are in a contracted state, so that the first baffle 4 and the second baffle 5 are in a state of opening the inlet and outlet of the heating channel 11, so that the aluminum rod can be fed into the heating channel 11 or pushed out. During the heating process of the aluminum rod, to ensure the airtightness of the heating environment, the first electric cylinder 6 and the second electric cylinder 7 are both extended, so that the first baffle 4 and the second baffle 5 cover the inlet and outlet of the heating channel 11. Through the coordinated use of the first electric cylinder 6 and the second electric cylinder 7, the automation of the feeding and discharging process of the heating furnace is realized, manual operation is reduced, so that the operator can easily manage the heating process, reduce the difficulty of operation and labor intensity, and improve production efficiency and safety.

[0033] In one embodiment, it further includes a first heat insulation plate 8 and a second heat insulation plate 9 , wherein the first heat insulation plate 8 is disposed on the inlet side of the heating channel 11 , and the second heat insulation plate 9 is disposed on the outlet side of the heating channel 11 .

[0034] In the above embodiment, the setting of the heat-insulating box 3 effectively improves the heating efficiency and reduces energy consumption, and prevents a large amount of heat from being emitted from all sides of the aluminum rod heating furnace to endanger the personal safety of the staff, and further prevents heat from being emitted from the axial direction of the heating channel 11. The first heat insulation board 8 and the second heat insulation board 9 can achieve the above effects, and improve the heating efficiency and safety, while reducing energy consumption. The first heat insulation board 8 and the second heat insulation board 9 are respectively arranged on the inlet side and the outlet side of the heating channel 11, fully covering the heat-resistant plate 1, the heating frame 2 and the heat-insulating box 3, optimizing the heating environment and further improving the overall heating performance.

[0037] In one embodiment, a loading platform 10 is further included, and the loading platform 10 is disposed on a side of the first heat insulation board 8 away from the heating channel 11. The loading platform 10 is provided with a positioning groove 101 corresponding to the heating channel 11.

[0038] In the above embodiment, the loading platform 10 is arranged on the side of the first insulation board 8 away from the heating channel 11, that is, the side corresponding to the feed port 81, and is used for temporary storage of aluminum rods during the loading process. The loading platform 10 has positioning grooves 101 corresponding to the number of heating channels 11. Each positioning groove 101 precisely corresponds to the position of a heating channel 11, ensuring that the aluminum rods can be accurately fed into the corresponding heating channel 11 for heating treatment. The positioning groove 101 has the same shape as the heating channel 11. For example, when the heating channel 11 is set as a cylinder, the positioning groove 101 is a corresponding arc.

[0039] In one embodiment, the loading platform 10 is provided with a cylinder 102 corresponding to the heating channel 11 .

[0040] In this embodiment, the feeding platform 10 is provided with a cylinder 102 at the position corresponding to each heating channel 11. The cylinder 102 is directly mounted on the feeding platform 10. The end of the push rod of each cylinder 102 is provided with a block suitable for pushing the aluminum rod, such as a block. The axis of the push rod of the cylinder 102 is preferably set to correspond to the axis of the heating channel 11, and can also be set to be slightly higher than the lowest end of the heating channel 11, which can be adapted to smaller aluminum materials. By arranging the cylinder 102 in the feeding platform 10, the automatic transportation of the aluminum rod from the feeding platform 10 to the heating channel 11 is realized, further improving the automation level and work efficiency of the entire heating furnace.

[0041] In one embodiment, a controller 103 is further included, and the controller 103 is disposed outside the heat-insulating box 3 . A temperature sensor 104 is further included, and the temperature sensor 104 is disposed between the heat-resistant plate 1 and the heating frame 2 and is electrically connected to the controller 103 .

[0042] In this embodiment, the controller 103 is arranged on the outside of any side of the heat-insulating box 3 that is different from the inlet and outlet of the heating channel 11, and can receive and process data from the temperature sensor 104, and control various operations of the heating furnace according to the preset heating program, including temperature adjustment of the heating frame 2, and control of the first electric cylinder 6 and the second electric cylinder 7 to realize the opening and closing of the first baffle 4 and the second baffle 5, and control of the cylinder 102 to realize automatic loading and unloading. The temperature sensor 104 is installed between the heat-resistant plate 1 and the heating frame 2, and is electrically connected to the controller 103. It can be set to multiple or at any position between the heat-resistant plate 1 and the heating frame 2. It is responsible for real-time monitoring of the temperature in the heating channel 11 and transmitting the temperature data to the controller 103, so that the controller 103 can adjust the heating parameters according to the actual temperature to ensure that the heating process reaches the optimal state.

[0043] Furthermore, the working process of the aluminum rod heating furnace is roughly as follows: when the aluminum rod heating furnace needs to work, the operator first sets the required heating parameters on the controller 103, including heating temperature, heating time, etc. The controller 103 controls the control of the first electric cylinder 6 and the second electric cylinder 7 to realize the opening and closing of the first baffle 4 and the second baffle 5. The aluminum rod is automatically fed into the heating channel 11 through the loading platform 10 and the cylinder 102. Subsequently, the heating furnace starts to heat the aluminum rod according to a preset program. During the heating process, the temperature sensor 104 continuously monitors the actual temperature in the heating channel 11 and transmits the data to the controller 103 in real time. The controller 103 compares the received temperature data with the preset target temperature. If a temperature deviation is detected, the controller 103 will automatically adjust the heating parameters (such as heating power, heating time, etc.) to ensure that the heating process is always carried out in the best state. After the heating is completed, the controller 103 will control the control of the first electric cylinder 6 and the second electric cylinder 7 again to realize the opening and closing of the first baffle 4 and the second baffle 5, so that the heated aluminum rod can exit the heating channel 11 to complete the entire heating process.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
