Small wire composite rolling mill based on high-frequency power supply heating

The invention relates to the technical field of composite rolling mills, in particular to a small wire composite rolling mill based on high-frequency power supply heating, which comprises a bottom plate, an upper rolling plate, a heating shell, a lower rolling plate, a plurality of support columns, two upper rollers and two lower rollers, the upper ends of the multiple supporting columns are fixedly connected with a top plate, and the two lower rollers are rotationally arranged between the multiple supporting columns. A mounting box is fixedly connected to the upper surface of the top plate, two rotating shafts are rotationally connected into the mounting box, a servo motor is arranged on one side of the mounting box, one rotating shaft is fixedly connected with the driving end of the servo motor, and a circular plate is fixedly connected to each rotating shaft. The distance between the upper roller and the lower roller can be adjusted according to the actual thickness of a wire, so that the limitation of the
