Usage: the set of the wire drawing machine is an ideal equipment wire drawing stock of high, medium and carboon steel, as well as copper, aluminium and alloy. The wire drawing machine is applied to drawing wires in the factories such as wire-steel factory, metal mesh factory, and nail making factory.
  Structure: the equipment consists of main reduction box, die casing, wheel frame, wire brace and electrical control system. The spinning drawing blocks are driven by JZT or Y series motor, with gear coupling runs changeful gears to reduce speed. The drawing blocks are verticaly fixed in sealed box body. The gear pair are lubricated with oil.
  In order to lower residual heat on the surface of the block, the cooling means is installed in interwall of the block. The machine runs with carwl or linkage. The safety halt gear is installed by the position of operation block.

Single block wire drawing machines include means for holding the dies accurately in position and for drawing the wire steadily through the holes. The usual design consists of a cast-iron bench or table having a bracket standing up to hold the die, and a vertical drum which rotates and by coiling the wire around its surface pulls it through the die, the coil of wire being stored upon another drum or "swift" which lies behind the die and reels off the wire as fast as required. The wire drum or "block" is provided with means for rapidly coupling or uncoupling it to its vertical shaft, so that the motion of the wire may be stopped or started instantly. The block is also tapered, so that the coil of wire may be easily slipped off upwards when finished. Before the wire can be attached to the block, a sufficient length of it must be pulled through the die; this is effected by a pair of gripping pincers on the end of a chain which is wound around a revolving drum, so drawing the wire until enough can be coiled two or three times on the block, where the end is secured by a small screw clamp or vice. When the wire is on the block, it is set in motion and the wire is drawn steadily through the die; it is very important that the block rotates evenly and that it runs true and pulls the wire at a constant velocity, otherwise "snatching" occurs which will weaken or even break the wire. The speed at which the wire is drawn vary greatly, according to the material and the amount of reduction.

Continuous wire drawing machines differ from the single block machines in having a series of dies through which the wire passes in a continuous manner. The difficulty of feeding between each die is solved by introducing a block between each die. The speeds of the blocks are increased successively, so that the elongation is taken up and any slip compensated for. One of these machines may contain 3 to 12 dies. The operation of threading the wire through all the dies and around the blocks is termed "stringing-up". The arrangements for lubrication include a pump which floods the dies, and in many cases also the bottom portions of the blocks run in lubricant.

Often intermediate anneals are required to counter the effects of cold working, and to allow more further drawing. A final anneal may also be used on the finished product to maximize ductility and conductivity.
