The pulley wire drawing machine is a non-slip dry continuous wire drawing machine that can be integrated. During the drawing process, the wire and the surface of the reel do not slide relative to the circumferential direction of the reel, and the surface wear of the two is relative. It is relatively small, and when a reel in the middle is temporarily stopped, the reels behind it can still work as usual for a period of time depending on their respective accumulated line quantities.
This kind of wire drawing machine has the advantages of simple structure, convenient operation and maintenance, low manufacturing cost, etc. At the same time, it has a certain wire accumulation coefficient, and the steel wire stays on the coil for a long time, which is conducive to the full cooling of the steel wire. It is suitable for drawing small and medium-sized steel wires and other metal wires with relatively low quality and strength requirements.
Due to the torsion of the wire during the drawing process of the pulley wire drawing machine, the double drum wire drawing machine was developed on the basis of the pulley wire drawing machine. This model has the advantages of a pulley wire drawing machine, and eliminates the torsion of the steel wire during the drawing process, and the cooling effect of the steel wire on the reel is better.
In order to further improve the quality and drawing speed of the wire, a looper wire drawing machine is introduced, which simplifies the route of the wire between the reels, and the wire will not be twisted axially during the drawing process. Driven by a DC motor, it can realize a wide range of stepless speed regulation, expand the selection range of the elongation rate between the reels, and the wire drawing machine can run in a reasonable working state.
And the looper produces a pulling or counter-pulling force on each roll during the drawing process. In the drawing with looper pulling force and looper reverse pulling force, the drawing force can be reduced, the life of the wire drawing die can be prolonged and the kinetic energy consumption can be reduced.
In order to make up for the inability of many wire drawing machines to draw large-sized steel wires and superhard materials, a straight-forward wire drawing machine was developed. After the steel wire is wound several times on the previous reel, it directly enters the next wire drawing die and is wound on the next reel without passing any wire guide pulley in the middle, and the steel wire between the two reels is straight. Simple threading, no twisting and small radius bending of the wire during the drawing process.
