Process control for metal cold forming

The instruments, with recently updated software and keyboard, are designed to be user-friendly and easy to use, with refined features of signal analysis and performances. They are available in black and white and in colour. Eldes’ project department is contin- uously working on further development of products and technology, on the improvement of the user interface and of

Since 1983 Eldes has been producing and installing real time control systems for metal cold forming, both cold headers and thread rolling machines. The systems are based on the measure of the force developed in the production process, by means of piezoelectric sensors applied to the sensitive points of the structure. It is thus possible to stop the machine if anomalies arise.

measurement methods. Eldes can also supply dedicated systems for customised applications, in addition to the standard instruments. Dedicated technology for production data collection (Prodat 2K) and dimensional measures acquisition systems (Themis) is also available.

Based on top-level technology and experience, Eldes has developed a new generation of process monitoring: Helios 2K, supervises production in metal cold forming plants using single stroke multi-stations cold headers and two blow cold headers. Titanus 2F is the corresponding device for thread rolling plants.

Tension measurement In the various processes of wire and cable manufacturing there are many parameters that are measured and controlled. Of these, tension is among the most important. The tension in wire or cable at the payoff and take-up points, as well as during common operations such as drawing, stranding or extruding, plays an influential role in process efficiency and product quality and performance. A lack of tension measurement and control can lead to product defects, substandard production levels and wasted money.

Tensometric’s new electronic tension meter, Combi 490, offers precision across a wide measuring range – up to 1,000 N. The unit gives a digital display of measured values. It is small (operation is one-handed) and is easily threaded into the running material. Display damping can be activated, to give a stable and smooth display even during fluctuating tensile forces. At the push of a button the last indicated measured value is held. Tensometric Messtechnik GmbH – Germany Fax : + 49 202 599084 Email : info@tensometric.com
