“Breakthrough” in breakdown technology

RBL 1 saves energy and materials m m

diameter is between 0.88mm and 5.5mm for copper, and between 1.25mm and 5.5mm for alloy. Advantages of the RBL 1 over existing technology are said to include: CNC process control • Diameter or conductivity operation • modes 30% less energy consumption • Quieter running, less than 80 dBA • Oil-free, direct drive technology • Operator-friendly supervision and • diagnostics systems Remote control via Internet • connection No preventative maintenance •

Headlined as “Rod breakdown with breakthrough technology” Sampsistemi launched the RBL 1 at this year’s wire Düsseldorf. The RBL 1 design includes continuous, high precision process control that saves energy and materials. Working with copper or aluminium alloys, the RBL 1 rod breakdown line will handle between 9 and 17 drafts of 1, 2 or 4 wires at speeds up to 40m per second. Wire elongation per draft is fully variable and selectable. The inlet diameter for copper wire is from 8mm to 10mm, or 9.5mm to 12.7mm for aluminium alloy; the outlet

Optical measurement

In highly automated production processes, length and velocity data are required for many purposes. For instance, measurement of operational throughput delivers essential data to control process parameters. In the manufacturing of piece goods an automatic start and end recognition mechanism enables an autonomous length measurement. For a variety of materials, especially those that are hot, elastic, highly sensitive, or dough-like, it is impossible to use tactile sensors such as odometers or tacho rolls. The accuracy of a mechanical sensor system is also reduced by slippage, which in practice can lead to measuring errors of 10% or more. In both cases, non-contact optical metrology provides significant benefits. With the Speel 3000, Zumbach offers a high-tech gauge that can be used for a wide range of applications requiring very high accuracy at very high velocities. The Speel 3000 is available for a measuring distance of 300mm and achieves an accuracy of 0.05% or better. The measured length is transmitted to subsequent electronics using an industry standard incremental interface. As an alternative, a synchronous serial interface (SSI) is also available. In addition, an electrical output signal compatible with common incremental encoders is available and can be directly connected to control systems, electrical counters, or frequency inverters.
