Measuring and control equipment from Zumbach

Drawing dies from Koner

Zumbach Electronic AG offers a wide range of dimensional mea- surement and quality monitoring systems for the wire and cable industry. Zumbach systems are designed to provide manufacturers with the state-of-the-art in process control technology. For wall thinkness scanning, Zumbach’s new design of transducers, incorporated in the new UMAC® Z50 and Z100 scanners, can be synchronously adjusted to the best possible measuring position within seconds. The scanners cover an outside diameter range from 5mm to 100mm.

Lubrication is a crucial factor for the finished quality of drawn wire. An interrupted lubrication in the drawing process causes an increase in surface tension in the wire, strong pressures inside the die, rapid die wear, breakage of the drawing nib and consequent non-programmed interruptions. To avoid these problems, Koner has developed a new concept in drawing dies – K.340 and K.370 pressure drawing dies (patented worldwide), specially constructed and designed to improve lubrication in dry drawing. With its revolutionary concept, these drawing dies become real dismountable drawing tools, adapted to meet all operating requirements. For wet drawing the K.320 tool has been created. Its particular inside geometry allows optimum wet drawing process characteristics and economic savings. K.340, K.370 and K.320 methods provide considerable operating advantages: Maximum drawing speeds Reduced downtime to replace die Better and homogeneous wire quality Wire drawing under optimumquality control Nib life increased by 30% and more Overall costs reduced by around 40% (change only the nib, not the entire die) Control of lubricant coating to the wire Better wet or dry redrawing operations Overall dimensions of K.340, K.370 and K.320 tools are the same as for traditional dies Savings on transport. Large quantities of nibs can be delivered rapidly in small packages to any part of the world Elimination of die rejects and the accumulation of worn drawing dies as worn tungsten carbide parts can be sold.

Institute of Spring Technology (IST) training course in India sponsored by the IWMA Educational Trust On November 23 rd Mark Hayes, Senior Metallurgist at IST, gave an IWMA Trust sponsored training course on the‘Manufacture and Design of Compression Springs’. The course was given at the Residency Hotel in Mumbai and was attended by 29 delegates from 22 different companies – 20 from India, one from Syria and one from Spain. The photograph below was taken during the afternoon of the course.

Feedback received from the course delegates has been entirely positive so far, and it is planned to hold another course in Southern India next year on‘Manufacture and Design of Extension and Torsion Springs’.
