Wire Drawing Machine Is conducive to the full cooling of the wire

The characteristics of various continuous drawing machine

2.1 pulley wire drawing machine

It is a kind of non-slip dry continuous drawing machine; in the drawing process, in the circumference of the drum and the drum surface along the circumference of the drum is not relative to the sliding direction, the two surface wear is relatively small, And when the middle of a reel temporary parking, the back of the reel can still rely on their own plot to work as usual for some time. The model has the advantages of simple structure, convenient operation, easy maintenance and low manufacturing cost. At the same time, it has a certain integral coefficient, and the length of the steel wire on the roll is longer, which is beneficial to the full cooling of the wire. But the wire guide wheel more, not only increased the number of bending wire, and the product of the reel, the wire in the drawing process along the axis of their own twist, seriously affecting the internal quality of steel wire and surface quality.

This feature of the pulley-type wire drawing machine determines that the model is only suitable for drawing, small size, relatively low quality and strength requirements of the wire and other wire.

2.2 double drum type drawing machine

As the pulley wire drawing machine in the drawing process will produce torsion of the wire, which in the pulley-type drawing machine on the basis of the development of a double drum-type wire drawing machine. The model has the advantages of pulley wire drawing machine and eliminates the torsion of the wire during drawing, and the cooling effect of the wire on the reel is better.

Double-roll wire drawing machine and pulley-type wire drawing machine, the guide wheel more, especially between the upper and lower reel between the middle of the wire guide wheel, so that when the wire through it 180. Bending, it is not suitable for drawing large size and high strength of the wire; machine operation is not as convenient as the pulley, and the upper and lower rolls between the friction ring and wire wheel and other parts of the inertia is very large, limiting the drawing speed. This model belongs to the pulley type wire drawing machine to the higher level drawing machine development of the transition model, suitable for drawing, small size steel wire.

2.3 sets of nesting wire drawing machine

In order to further improve the quality of steel wire and drawing speed, the development of the nesting wire drawing machine, it is also a non-sliding wire drawing machine; it simplifies the wire between the rollers of the line, in the drawing process, Resulting in axial torsion, and because of the use of DC motor drag, to achieve a wide range of stepless speed regulation, expanding the extension between the use of the scope of the selection, drawing machine in the most reasonable working conditions. And live sets in the drawing process for each reel have produced a pull or anti-pull force. In a set of tension and a set of anti-pull pull pull, can reduce the pull force to extend the life of drawing die and reduce the kinetic energy consumption of live sets of wire drawing machine is a continuous speed control of the continuous drawing machine, from In theory, in the wire to the compression rate of the ultimate limit and the machine within the force parameters, as long as the total process compression ratio is greater than or equal to the total compression rate of the machine, for any kind of technology can automatically adjust the machine to complete the drawing process The Therefore, the nesting wire drawing machine is a more advanced drawing machine, suitable for drawing small and medium size high strength steel wire and alloy wire.
