Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, and more specifically to an induction heating device for processing aluminum rods. Background Technology

[0002] During the extrusion process of aluminum profiles, aluminum rods need to be fed into a heating furnace for heating until they reach a molten state. Then, they are sent to a cutting device to be cut to the required length, and finally conveyed to an extrusion device for further extrusion. An aluminum rod heating furnace is a device that heats aluminum rods to change their mechanical properties and improve the quality of the processed products. An aluminum rod induction heating furnace is a power supply device that converts 50Hz AC power into medium-frequency (300Hz to 1000Hz) power. It rectifies three-phase AC power into DC power, then converts the DC power into an adjustable medium-frequency current, which is supplied to the medium-frequency alternating current flowing through the capacitor and induction coil. This generates high-density magnetic lines of force within the induction coil, cutting the metal material inside and generating large eddy currents in the metal. It features small size, light weight, high efficiency, excellent heat processing quality, and is environmentally friendly.

[0003] An existing technology includes a rapid heating furnace for multiple aluminum rods, comprising a furnace body with a feed inlet and a discharge outlet on the left and right sides of the rear end of the furnace body, respectively. A conveyor belt is rotatably installed on the left and right sides of the lower part of the furnace body, and several rows of limit plates are evenly spaced on the outer surface of the conveyor belt. A turning roller is rotatably installed between the two conveyor belts, and several rows of turning plates are evenly spaced on the outer surface of the turning roller. However, this rapid heating furnace has some problems in actual use. For example, the aluminum rods cannot be smoothly transferred due to the presence of conveyor belts at both the front and rear. The rapid cooling caused by the aluminum rods affects the physical properties of the aluminum material after processing. Utility Model Content

[0004] One advantage of this invention is that it provides an induction heating device for aluminum rod processing.

[0026] The first embodiment of this utility model is as follows:

[0027] An induction heating device for aluminum rod processing includes a frame, on the upper part of which are sequentially arranged a feeding component for pushing aluminum rods, an induction heating component for receiving aluminum rods and heating them by induction heating, a heat preservation component for extending the cooling time of aluminum rods by using hot air in the induction heating component, and a feeding component for conveying the cooled aluminum rods away.

[0028] The feeding assembly includes a hydraulic cylinder 1 fixedly installed at one end of the upper part of the frame. The hydraulic cylinder 1 is connected to a piston rod 2 in a telescopic manner. The other end of the piston rod 2 is fixedly connected to a push plate 3. A V-shaped conveyor plate 4 is also provided on the upper part of the frame. The V-shaped conveyor plate 4 is located between the hydraulic cylinder 1 and the heating furnace 5. The diameter of the push plate 3 is smaller than the diameter of the circular cavity.

[0029] The induction heating assembly includes a heating furnace 5 fixedly installed on the upper part of the frame. The heating furnace 5 has a circular cavity inside and an induction coil 6 is installed inside the heating furnace 5. The circular cavity is located inside the induction coil 6. A mounting bracket 19 is fixedly installed on the lower part of the frame. A power supply device 18 is installed on the mounting bracket 19 and is electrically connected to the induction coil 6.

[0030] The power supply unit 18 converts the 50Hz AC power to a medium frequency of 300Hz to 1000Hz. It rectifies the three-phase AC power into DC power and then converts the DC power into an adjustable medium frequency current. This DC power is supplied to the medium frequency alternating current flowing through the capacitor and the induction coil 6. This generates a high density of magnetic lines of force in the induction coil and cuts the aluminum rod in the induction coil. Large eddy currents are generated in the aluminum rod, which in turn raises the temperature.

[0031] When the aluminum rod is placed on the V-shaped conveyor plate 4, its position corresponds to the circular cavity of the heating furnace 5. At this time, the hydraulic cylinder 1 drives the piston rod 2 to move forward, pushing the aluminum rod into the heating furnace 5, and then moves to the rear.

[0032] To process multiple aluminum bars simultaneously, multiple sets of feeding components and induction heating components can be arranged side by side to work synchronously.

[0033] After heating is complete, the aluminum rod is pushed forward by the piston rod 2 and the push plate 3 until it moves onto the conveyor roller 10.

[0034] The feeding assembly includes several conveyor rollers 10 that are rotatably connected to the frame. Several conveyor rollers 10 near the heating furnace 5 are located inside the heat preservation box 9, receive the aluminum rods removed from the heating furnace 5 and move them forward.

[0035] One end of each conveyor roller 10 is equipped with a driven wheel 17, and the end of the outermost conveyor roller 10 is equipped with a driving wheel 11. The driving wheel 11 and the driven wheel 17 are connected by a second transmission belt 16, and adjacent driven wheels 17 are also connected by a second transmission belt 16. A motor 15 and a transmission wheel 12 are mounted on the lower part of the frame. The output shaft of the motor 15 is connected to an output wheel 14. A first transmission belt 13 is provided between the output wheel 14 and the transmission wheel 12, and between the transmission wheel 12 and the driving wheel 11. Power is output from the motor 15, which, through several first transmission belts 13 and second transmission belts 16, causes the driven wheels 17 and the driving wheel 11 to rotate, thereby moving the aluminum rod forward.

[0036] The feeding assembly also includes an inclined feeding plate 21, with its upper end near the outermost conveyor roller 10. When the aluminum rod moves to this point, it will move onto the feeding plate 21. Several legs 22 are provided at the bottom of the frame, and support rods 20 are provided on the legs 22 near the feeding plate 21. The other end of the support rods 20 is connected to the middle of the feeding plate 21. The support rods 20 enhance the stability of the feeding plate 21.

[0037] The insulation component includes an insulation box 9 fixedly installed on the upper part of the frame. Both ends of the insulation box 9 are provided with openings for aluminum rods to pass through. A fan 8 is provided on the upper part of the insulation box 9. The fan 8 is connected to an air duct 7. The other end of the air duct 7 is connected to the heating furnace 5.

[0038] When the aluminum rod is heated in the heating furnace 5, hot air is generated. The fan 8 draws this hot air into the insulation box 9 to raise the temperature inside the insulation box 9, thereby extending the cooling time of the aluminum rod, preventing the aluminum rod from cooling down too quickly, and avoiding excessive temperature difference between the end and the middle.

[0039] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
