Schwarze-Robitec at Tube 2012: Bend to the Right – Bend to the Left: Without Reclamping. In One Go.

As the first supplier on the international market for tube bending machines, with the newly developed CNC 40 Rotary, Schwarze-Robitec GmbH offers a CNC-controlled, tube cold bending machine for bending tube systems to the left and to the right. This is facilitated by an additional CNC axis from the loosely mounted bend former in the innovative bending head. The CNC 40 Rotary therefore considerably increases the flexibility of bending processes – even in the case of tubes with shapes already preformed on the straight tube and in the case of additional functions such as the filling mandrel device. It processes tubes with diameters from 8 mm to 40 mm. At Tube 2012 – from 26th to 30th March in Düsseldorf – the unrivalled solution will be presented to the specialist public for the first time on stand E27 in hall 5. Moreover, Schwarze-Robitec will be showing the energy-efficient CNC 100 E TB MR tube bending machine and the high-performance TPM-1 tube perforating machine.

COLOGNE. Schwarze-Robitec has developed the current solution in order to allow time and cost effective processing by users in the future. “Put simply, the use of the loosely mounted bend former allows the bending head to move independently of the tool,” explains Schwarze-Robitec GmbH Manager Bert Zorn. The advantage of this is that even tubes with the smallest bending radii and complex curve shapes after bending can be easily moved out of the range of collisions and interfering contours. As this new solution needs no second bending head, Schwarze-Robitec has been able to reduce the investment in the CNC 40 Rotary by around 20 percent when compared to conventional solutions, explains Schwarze-Robitec GmbH Manager Hartmut Stöhr. Aside from these massive reductions of acquisition costs, the new tube bending machine, which works with up to 13 CNC-axes is remarkable for its intuitive operator guidance on the control system. “A single day of initial practice is enough to understand the control concept and operate the machine intuitively,” explains Bert Zorn.

In addition to this new development, Schwarze-Robitec will be exhibiting the high-performance CNC 100 E TB MR tube bending machine and the TPM-1 tube perforating machine at Tube 2012. The fully electric CNC 100 E TB MR is suitable for bending tubes with diameters between 25 mm and 114.3 mm. This machine is also equipped with a loosely mounted bend former and with transport boost and multi-radius technology, which allow automated bending on several levels. It also has a combined bending tool for mandrel bending with extra curve clamp jaws and a hydraulic separating unit. The advantage of this is that even tight radii and short intermediate lengths can be produced on one tube in a single operation. “Furthermore, the CNC 100 E TB MR is more energy efficient than comparable machines,” as Schwarze-Robitec Sales Manager Jürgen Korte knows. Other advantages, such as the ergonomic loading height and the fully automated level changing, come into effect both with the CNC 100 E TB MR and with the CNC 40 Rotary. As a third exhibit, the tube processing specialist from Cologne will be showing the TPM-1 tube perforating machine, which punches entire rows of holes in tubes with a thickness of up to 2 mm. The machine is able to process tubes up to 70 mm in diameter and 500 mm in length. It performs the processing stages of punching, perforating and cutting to length in one go.
