process to continuous quality control of the bent parts.” One significant topic on the Schwarze- Robitec trade fair stand is the energy efficiency of tube bending machines. Different energy-saving concepts ensure optimum handling of valuable resources. As such, an improved energy balance is achieved in the case of electrical drives, including by the use of innovative feed- in and recovery modules. Hydraulic tube bending machines save energy, eg with adjustable pump drives. Hybrid drives also achieve convincing results. “The purchase of energy-efficient machines pays off not only in the light of high energy prices, stricter international legislation and increasing energy awareness,” Mr Zorn emphasised. “Investments of this nature are subsidised in many cases – with certain restrictions – by one’s own state or by the EU through energy efficiency programmes, or they are promoted through reduced interest on borrowing.” The processing of new, high-strength materials is a second central focal point of the trade fair for the tube bending specialists; the cold reshaping of harder materials requires significantly greater bending forces. At the same time, the materials react more sensitively.

AT EuroBLECH 2012 in Hanover, Siempelkamp will present presses for the complete manufacturing process of large-diameter pipes via C-, U- and O-forming. As a single-source systems provider, Siempelkamp not only offers the machine engineering, but also demonstrates the processing technology for all three applications. For O-forming presses Siempelkamp has developed an improved control concept: the incoming steel cannings are generally positioned in the press centre. Therefore, independent of the length of the workpiece, the press force is introduced exactly into the plate. This results in a better load distribution and, at the same time, a lower mechanical load. Furthermore, Siempelkamp has optimised its proven tooling concept featuring exchangeable shells. The outline of the half-shells, which were optimised with the finite-element method, evens out deformations from the tools in transverse directions. Combined with the patented tool clamping, which compensates the occurring forces in longitudinal direction, Siempelkamp has achieved the optimal pipe geometry for the subsequent production steps. Once more a new order of a long- standing customer proves that Siempelkamp has set the right course with its C-, U- and O-forming presses.

With a new control system it is featured by particular energy efficiency. A particular feature of the Tenaris

Schwarze-Robitec GmbH Germany Hall 11 Stand C06 SCHWARZE-ROBITEC, a manufacturer of tube cold-bending machines, will present its broad spectrum of solutions at EuroBLECH, ranging from tube bending machines and fully equipped, automatic tube bending production lines to measuring devices and bending tools, tube perforating and special machines. Particular emphasis is placed on energy-efficient solutions as well as machines for bending new, high- strength materials. The company will present its extended portfolio of bending machines for processing tubes with diameters between 4 and 420mm to specialist visitors at EuroBLECH. Tailored to the individual requirements of the automotive, shipbuilding and offshore industry, power plant construction, the chemical industry and the aerospace industry, the bending specialist offers a range of machines and accessories that can be configured in modules. One major focus is on the comprehensive advisory competence for the different production concepts. “Together with our customers, we always produce an individual solution that is tailored precisely to the needs of the user,” said managing director Bert Zorn. “This might be a newly developed bending tool, a bending machine that can be specifically configured, or even a complete, fully automated bending line – from tube separation through production
