Description

Technical Field

[0001] This utility model relates to the field of aluminum profile production, and in particular to a mold induction heating furnace for an aluminum profile extrusion production line. Background Technology

[0002] Heating aluminum profiles is a common process in industrial production, widely used in forming, welding, heat treatment and other processes. Induction heating furnaces use the principle of electromagnetic induction to generate eddy currents inside the aluminum material, resulting in rapid heating.

[0003] Chinese utility model patent CN02269920.1 discloses an induction heating furnace for molds used in aluminum profile extrusion production lines. The furnace shell has a support bracket at the bottom, on which a mold temperature measuring thermocouple is mounted. Two opposing plate-type electromagnetic induction heating coils are placed inside the furnace. A furnace temperature measuring device and a temperature control device are mounted on the top of the furnace shell. An insulation layer is provided on the inner wall of the furnace shell, and a limiting mechanism is installed at the bottom of the furnace. This utility model can be used for induction heating of molds in aluminum profile extrusion production lines.

[0004] However, the induction heating furnace used on the aluminum profile extrusion production line adopts a vertical plate electromagnetic induction heating coil. The aluminum profile is placed between two plate electromagnetic induction heating coils for heating. Conventional brackets usually rely on conveying equipment for transportation. Since the conveying equipment is mostly made of metal, the conveying equipment used for transportation will also be heated by the plate electromagnetic induction heating coil, which is not conducive to use. Utility Model Content

[0005] In view of this, the present invention provides a mold induction heating furnace for an aluminum profile extrusion production line. The main technical problem to be solved is to improve the conveying structure in the induction heating furnace and avoid heating the conveying structure at the same time as the electromagnetic induction heating coil heats the aluminum profile, which would reduce the life of the conveying structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an induction heating furnace for an aluminum profile extrusion production line, comprising an outer shell, a support installed inside the outer shell, and two supports arranged opposite to each other, a rotating column installed at one end of each support, a rotating frame movably connected to the outer surface of the rotating column, a cylinder installed on the outer surface of the support, a moving block movably connected to the end of the cylinder away from the support, a moving groove opened on the lower surface of the rotating frame, the moving block located inside the moving groove, a plate-type electromagnetic induction heating coil fixedly connected to the inner wall of the outer shell, a placement rack arranged above the support, and an aluminum profile arranged on the surface of the placement rack.

[0007] By adopting the above technical solution, the rotation of the rotating frame can be controlled by the operation of the cylinder. When the rotating frame is in a horizontal position, the two supports can be connected, allowing the placement frame to move on the two supports. When the rotating frame is in a vertical position, the operation of the plate electromagnetic induction heating coil can avoid affecting the rotating frame. In use, the placement frame can be made of non-metallic material, so that when the plate electromagnetic induction heating coil is energized, it only heats the aluminum profile on the placement frame and does not affect the placement frame.

[0008] As a further description of the above technical solution:

[0009] The bracket is internally connected to a rotating shaft, and there are multiple rotating shafts. Rollers are fixedly connected to the outer surfaces of the multiple rotating shafts.

[0010] By adopting the above technical solution, the roller can rotate inside the support.

[0011] As a further description of the above technical solution:

[0012] The support frame is equipped with a conveyor belt, and the roller is located inside the conveyor belt, with the outer surface of the roller in contact with the inner surface of the conveyor belt.

[0013] By adopting the above technical solution, the roller can move along the conveyor belt when it rotates, and the placement rack placed on the conveyor belt can move on the support.

[0014] As a further description of the above technical solution:

[0015] A motor is fixedly connected to the outer surface of the bracket, and the output end of the motor is fixedly connected to one end of the rotating shaft.

[0016] By adopting the above technical solution, the rotation of the rotating shaft can be controlled by the operation of the motor, which in turn controls the rotation of the roller shaft, enabling the conveyor belt to move and thus driving the placement frame to move.

[0017] As a further description of the above technical solution:

[0018] The upper surface of the bracket has an inner groove, and a first roller is movably connected inside the inner groove. There are multiple first rollers, and the outer surface of the first roller is in contact with the lower surface of the placement frame.

[0019] By adopting the above technical solution, the first roller can assist the placement frame in moving on the support.

[0020] As a further description of the above technical solution:

[0021] The upper surface of the rotating frame is movably connected to a second roller, and there are multiple second rollers, with the outer surface of the second rollers fitting against the lower surface of the placement frame.

[0022] By adopting the above technical solution, the second roller can assist the placement frame in moving on the rotating frame.

[0023] As a further description of the above technical solution:

[0024] The number of plate-type electromagnetic induction heating coils is two, and the two plate-type electromagnetic induction heating coils are respectively located on the front and rear inner walls of the outer shell.

[0025] By adopting the above technical solution, aluminum profiles placed on the rack can be heated using a plate-type electromagnetic induction heating coil.

[0026] By employing the above technical solution, the induction heating furnace for an aluminum profile extrusion production line of this utility model has at least the following beneficial effects:

[0027] 1. Compared with the prior art, the mold induction heating furnace for aluminum profile extrusion production line can control the rotation of the rotating frame through the operation of the cylinder. When the rotating frame is in the horizontal position, it can connect the two supports, so that the placement frame can move on the two supports. When the rotating frame is in the vertical position, it can avoid the influence of the plate electromagnetic induction heating coil on the rotating frame.

[0028] 2. Compared with the existing technology, the mold induction heating furnace for aluminum profile extrusion production line can be made of non-metallic material when in use, so that the plate electromagnetic induction heating coil can only heat the aluminum profile on the placement rack after being energized, without affecting the placement rack.

[0036] Reference Figure 1-5 This utility model provides a mold induction heating furnace for an aluminum profile extrusion production line: It includes a shell 1, inside which two supports 2 are installed, arranged opposite each other. A rotating column 9 is installed at one end of each support 2, and a rotating frame 10 is movably connected to the outer surface of the rotating column 9. A cylinder 12 is installed on the outer surface of each support 2, and a moving block 13 is movably connected to the end of the cylinder 12 away from the support 2. A moving groove 14 is formed on the lower surface of the rotating frame 10, and the moving block 13 is located inside the moving groove 14. A plate-type electromagnetic induction heating coil 15 is fixedly connected to the inner wall of the shell 1. A placement rack 16 is provided above the supports 2 for placing the coil during use. The frame 16 can be made of non-metallic materials, such as a frame with a high-temperature resistant plastic bottom layer and a firebrick top layer. This allows the plate electromagnetic induction heating coil 15 to heat only the aluminum profile 17 on the frame 16 after it is energized, without affecting the frame 16 itself. The surface of the frame 16 is provided with aluminum profile 17. The rotation of the rotating frame 10 can be controlled by the operation of the cylinder 12. When the rotating frame 10 is in a horizontal position, it can connect the two supports 2, allowing the frame 16 to move on the two supports 2. When the rotating frame 10 is in a vertical position, it can prevent the plate electromagnetic induction heating coil 15 from affecting the rotating frame 10 when it is working.

[0037] The support 2 is internally connected to a rotating shaft 4, and there are multiple rotating shafts 4. Rollers 5 are fixedly connected to the outer surfaces of the multiple rotating shafts 4, so that the rollers 5 can rotate inside the support 2. A conveyor belt 6 is set inside the support 2, and the rollers 5 are located inside the conveyor belt 6, with the outer surface of the rollers 5 in contact with the inner surface of the conveyor belt 6, so that when the rollers 5 rotate, they can move the conveyor belt 6, allowing the placement rack 16 placed on the conveyor belt 6 to move on the support 2. A motor 3 is fixedly connected to the outer surface of the support 2, and the output end of the motor 3 is fixedly connected to one end of a rotating shaft 4. By operating the motor 3, the rotating shaft 4 can be rotated, which in turn controls the rotation of the rollers 5, allowing the conveyor belt 6 to move, and thus driving the placement rack 16 to move.

[0038] The upper surface of the support 2 is provided with an inner groove 7, and a first roller 8 is movably connected inside the inner groove 7. There are multiple first rollers 8, and the outer surface of the first roller 8 is in contact with the lower surface of the placement frame 16. The first roller 8 can assist the placement frame 16 to move on the support 2. The upper surface of the rotating frame 10 is movably connected with a second roller 11, and there are multiple second rollers 11. The outer surface of the second roller 11 is in contact with the lower surface of the placement frame 16. The second roller 11 can assist the placement frame 16 to move on the rotating frame 10.

[0039] There are two plate-type electromagnetic induction heating coils 15, which are located on the front and rear inner walls of the outer shell 1 respectively. The plate-type electromagnetic induction heating coil is a high-efficiency heating device designed based on the principle of electromagnetic induction. It can reduce energy loss and improve heating efficiency and uniformity in the process of converting electrical energy into heat energy. It adopts a flat spiral winding design, with a large heating area, so that the temperature distribution in the heating area is uniform. It is suitable for large-area or complex-shaped metal workpieces. The plate-type electromagnetic induction heating coils 15 can heat the aluminum profile 17 placed on the placement rack 16.

[0040] Working principle: The cylinder 12 can control the rotation of the rotating frame 10. When the rotating frame 10 is in a horizontal position, it can connect the two supports 2, so that the placement frame 16 can move on the two supports 2. When the rotating frame 10 is in a vertical position, it can avoid the plate electromagnetic induction heating coil 15 from affecting the rotating frame 10 when it is working.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
