Dynamic concepts for collision-free pipe bending

right/left bending con- cepts for different pipe diameters. In the development of these bending machines, the focus was on the optimum utilisation of the systems.

IN pipe bending, precision is critical. In order to ensure good results, the use of the right bending technology is becoming increasingly important. This is particularly true for challenging requirements such as installation space and system positioning, as they can restrict the conditions needed when forming pipes. In many cases, neither a right- nor a left-bending machine can produce the required geometry of the pipe bends without colliding with the machine frame. A solution with the maximum number of bending options is required. For this purpose, transfluid Maschinenbau has created technologies in its ‘t bend’ machine category, offering two effective

because the operation time is extremely short,” said Ms Flaeper. “Changing from one bending direction to another can be completed in 2.5 seconds.” Each bending head can be equipped with up to three tool levels. In the second bending concept, transfluid has optimised the machine’s effectiveness onto one rotating head. This system is also dynamic for larger pipe diameters from 30 to 90mm. Larger pipe dimensions can be efficiently bent right or left. The concept is the same for pipe diameters of less than 30mm; all shafts are servo-electrically driven and there are two tool levels on each bending head as standard. To free- form large radii, both machine versions can be equipped with a corresponding system. transfluid Maschinenbau GmbH – Germany

“For pipes with a diameter of less than 30mm, we offer a ‘t bend’ machine with two individually adjustable heads,” said Stefanie Flaeper, managing director at transfluid. The adjustable heads allow both right- and left-hand bending operations; the right bending head is still-standing, and the left bending head is suspended. “This design principle is very effective for small pipe diameters

Orbital cutting technology ROLF Schlicht’s orbital cutting technology is a new cutting system for small pipes used for the cutting of semi-rigid, rigid and brittle plastic pipes.

cutting of soft and semi-rigid extrudates up to about 50mm diameter at highest line speed and cutting cycles up to about 400/min in stop/start operation and up to 4,000/min with continuously rotating knife. Diverse feeding and discharging systems are available, being built according to customers’ demands. Rolf Schlicht GmbH – Germany Email: info@schlicht-gmbh.de Website: www.schlicht.gmbh.de

as well as high cutting and reaction speeds at rotation speeds up to 3,000rpm and 150 cuts per minute. It is used for OC-15 (up to 15mm Ø) for fuel pipes, small pipes requiring a clean cut face, medical technique, etc, and OC-40 (up to 40mm Ø) and OC-65 (up to 65mm Ø), and both machines are used for pipes which must not have swarf and where a clean cut area is important. RS Multicut rotation cutter MC-50 is for dry and wet applications for precise

The system improves on conven- tional cutting systems and techniques like punch cutters, guillotines, saws and also rotating cutters. This new technique is very precise and provides a clean, burr-free cut face. High flexibility is provided by setting and controlling process parameters
