l Lubrication – a crucial factor

Lubrication is one of the crucial factors for the quality of the drawn wire. Interrupted lubrication in the steel wire drawing process causes an increase of surface tension in the wire, strong pressures inside the die, rapid die wear, breakage of the drawing nib and consequent non- programmed interruptions in the wire drawing process. In order to avoid these problems, Koner has studied a new concept line of drawing dies – K.340 and K.370 pressure drawing die (patented worldwide), specially constructed and designed to greatly improve lubrication in dry drawing of steel wire. With its revolutionary concept, drawing dies becomes a real dismountable drawing tool, adapted to meet all operating requirements. For wet drawing the K.320, with its particular inside geometry, gives optimum wet drawing process characteristics and is also a great economic saving. The K.340/K.370/K.320 methods provide considerable operating advantages:

Operating advantages from the new drawing dies

• • • • • • • • •

production at maximum drawing speeds less machine down-time for die replacement better and more homogeneous wire quality wire drawing under optimum quality control nib life increased by 30% and more to traditional dies overall costs reduced by around 40% (you only change the nib, not the entire die) application of the requested quantity of lubricant coating to the wire better wet or dry re-drawing operations the overall dimensions of K.340/K.370/K.320 tools are the same as for traditional dies savings on transport – even large quantities of nibs can be delivered rapidly in small packages directly to customers elimination of die rejects and the accumulation of no longer useable drawing dies in the warehouse, return can be gained from the sale of worn tungsten carbide parts
