Referring to fig. 1-3, preferred embodiments of the present invention are shown.
The traditional method for preparing tungsten alloy ultra-fine wires is on-line heating tower wheel type slip drawing, the larger the slip between a tower wheel and a copper clad steel wire is, the more severe the surface wear of the tower wheel is, the uneven slip can shorten the service life of the tower wheel, therefore, an accumulative slip effect is considered, the accumulative slip effect is transmitted and accumulated in a continuous power mode from a finished product die to the wire inlet direction, the more advanced the pass is, the more severe the wear is, meanwhile, the more advanced the pass is, the thicker the wire diameter is, the larger the drawing load is, the larger the power loss is, the more severe the damage between the wire and the tower wheel is, the tower wheel is ground out of a groove, or the wire is thrown up to drive the die to shake during drawing, and the wire is stressed unevenly, and is slub-shaped or disconnected.
The disadvantage of this technique is mainly the sliding friction between the cone pulley and the metal filament in the cone pulley type slip drawing, which mainly brings about three disadvantages:
(1) The cost is improved: in order to reduce the sliding friction between the cone pulley and the metal filament, the requirements on the surface hardness, roughness and roundness of the coaxial cone pulley are increased, so that the operation difficulty and cost are improved;
(2) And (3) reducing the tensile strength: the surface of the cone pulley is abraded, so that the tungsten alloy ultra-thin wire is easy to have surface defects, the tensile strength of the tungsten alloy ultra-thin wire is reduced, 4300MPa is difficult to achieve, and the application range of the material is greatly limited;
(3) And (4) reducing the yield: frequent wire breakage is easy to occur in cone pulley drawing due to sliding friction, and the rate of finished products is greatly limited.
Compared with the existing cone pulley drawing, the method has the following main advantages that: the device adopts electromagnetic direct drive as power, so that relative sliding between a tungsten wire and a traction device is avoided, and friction damage to the surface of the wire material is avoided; the drawing force for traction can be dynamically set according to the wire diameter of the wire, so that the wire breakage probability is greatly reduced.
