Disclosed is a method for fabricating flat enamelled aluminium wires, relating to enamelled wire fabrication method. The invention adopts extrusion technique and equipment and squeezes out a flat aluminium wire profile through a die orifice under the action of high temperature and high pressure generated by friction. The fabrication method mainly includes the following steps: (1), straightening an aluminium pole; (2), washing the aluminium pole with neutral solution; (3), continuously squeezing the aluminium pole with special extrusion equipment into a flat aluminium wire; (4), cooling the flat aluminium wire water to below 60 DEG C; (5), coating insulation lacquer on the flat aluminium wire; (6), firing and drying the coated flat aluminium wire between 200 DEG C and 440 DEG C; and (7), cooling the flat enamelled aluminium wire in air to room temperature. In this way, a finished flat enamelled aluminium wire can be obtained. The special extrusion equipment comprises an extrusion wheel; a compression wheel is composed of a pair of opposite grinding compression rollers; and a circular groove is arranged at the center of the face of the extrusion wheel; a flow guide plate is arrangedat the upper part of the die orifice and a baffle is arranged at the lower part of the die orifice. The flat enamelled aluminium wire can be used on a transformer, a motor and particularly on intermittent products like a UPS electrical source or a regulator.

The invention provides a forming method and device for special-shaped wire rods. The device is equipped with a combination of a non-driven front 4-roller Turks Head (16) and a power-driven rear 4-roller Turks Head (17). The formed forming unit (15) is configured with a non-driven 4-side roll Turk head (21) of the finishing roll row in a straight row at the rear of the forming unit. The forming roll of the power-driven Turk head (17) has a diameter more than 70 times larger than the edge height of the material to be formed, and the formed roll between the non-driven Turk head (16) and the power-driven Turk head (17) The subject tension of the material is controlled below 300N, and the tension between the molding unit (15) and the complete Retek head (21) is controlled within the range of 50-200N for molding. Thus, special-shaped wires can be formed with high efficiency and high precision.
