[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. The production process of aluminum profiles mainly includes three processes: melting, extrusion and coloring. With the increasing application of aluminum profiles, the usage is increasing, especially in transportation. When the aluminum ingot is extruded in the extrusion barrel, due to the contact between the aluminum ingot and the surface of the extrusion barrel, when the aluminum ingot is extruded, high temperature will be generated due to extrusion and friction, which will affect the temperature of the extrusion barrel. It is difficult to control the temperature of the extrusion barrel to improve the high precision and high surface size performance of the aluminum extrusion.

[0003] In the prior art, there is a temperature deviation problem in the heating unit of the aluminum profile extrusion barrel, and a high-pressure air pump inflation method is often used to achieve rapid temperature adjustment (for example: authorized patent CN220329622U). However, since no high-temperature gas outlet structure is provided, the high-temperature gas still remains in the aluminum profile extrusion barrel, resulting in a slow temperature adjustment rate inside the aluminum profile extrusion barrel, which is not conducive to the forming and processing of the aluminum profile.

A plurality of insulation rings 12 are fixedly connected to the inner wall surface of the extrusion cylinder 1, and the plurality of insulation rings 12 are distributed in the gaps between the first heating unit 4, the second heating unit 5, and the third heating unit 6. A PLC controller 7 is fixedly installed on the support seat 2, and the output end of the PLC controller 7 is electrically connected to the solenoid valve 18, and the temperature sensor 17 is electrically connected to the PLC controller 7.

It is only used without modification, so the control method and circuit connection are not described in detail. The parts not involved in the aluminum ingot extrusion process in the device are the same as the prior art or can be realized by the prior art.

[0022] In one embodiment, multiple heating zones are formed between several insulation rings 12 of the extrusion barrel 1, and the multiple heating areas correspond to the first heating unit 4, the second heating unit 5, and the third heating unit 6. Through the multiple heating zones formed by several insulation rings 12, the heat between two adjacent heating zones can be blocked by the insulation rings 12 to meet the requirements of gradient heating.

[0023] In one embodiment, a clearance opening is opened on the lower surface of the support plate 3 corresponding to the exhaust pipe 10, and a mounting ear 11 with a screw hole is welded to the bottom of the support plate 3.

A plurality of heat-insulating rings 12 are used in the extrusion barrel 1 to form a gradient heating zone in the installation area of ​​the first heating unit 4, the second heating unit 5, and the third heating unit 6. When the aluminum ingot passes through the extrusion barrel 1, the heating arcs 14 installed in the first heating unit 4, the second heating unit 5, and the third heating unit 6 are started to ensure the uniformity of heating of various parts of the aluminum ingot in a gradient heating manner. At this time, the heating arcs 14 set in the first heating unit 4, the second heating unit 5, and the third heating unit 6 are set to heat the aluminum ingot uniformly. The temperature sensor 17 inside the first heating unit 4, the second heating unit 5 or the third heating unit 6 feeds back the temperature data to the PLC controller 7. When the aluminum ingot in one of the heating intervals of the extrusion barrel 1 generates high temperature due to extrusion and friction, the PLC controller 7 opens the solenoid valve 18 on the cold air duct 8 and the exhaust duct 10 branch pipe corresponding to the heating interval, prompting the cold air to be introduced into the first heating unit 4, the second heating unit 5 or the third heating unit 6 through the blowing hood 15, and the PLC controller 7 starts the exhaust fan 9, so that the suction hood 16 extracts the high-temperature gas at the corresponding position, thereby achieving the purpose of quick temperature regulation.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
