Bending

Freeform bending WITH the Nissin Freeformbender, produced by J Neu Machinery, it is possible to bend different radii of tubes and profiles in three dimensions without tool change. This is due to a patented tooling in combination with a CNC control system. handling of the machine quite easy. Bent parts can be compared and corrected automatically, and 3D CAD data can be used directly in order to prepare a bending program for the machine. A unique feature of this bender is the possibility to bend a real spline according to CAD files.

Radii can follow each other without straight lengths in between, and can be in different planes. The system achieves bent tube results with constant wall thickness and without thinning, suitable for a following hydroforming process or lightweight constructions. With a mandrel, thin-walled pipes with high precision can also be bent on the Nissin Freeformbender, up to a diameter of 90mm. The smallest achievable radius is close to 2DR. The same machine can bend not only round pipes but also flat oval, square and asymmetric profiles.

The Freeformbenders are currently available with three, five or six simultaneous axles combined with automatic loading and unloading devices. J Neu GmbH – Germany Fax: +49 6359 87248 99 Email: info@neu-gmbh.de Website: www.neu-gmbh.de

all handling requirements, even with bent pipe. Pipe lengths between 30 and 3,000mm can be processed at top speed. The different characteristics of systems also make combination a practical option, depending on the production task. The four-axis handling system and robot after bending can work together for additional handling tasks, and the control of both systems can be coordinated. Gripper changes are already optimised in both systems. To do this, transfluid developed special interior and exterior grippers that cover a wide spectrum of production requirements. Rotating and turning mechanisms round out the automation line for complex requirements. transfluid Maschinenbau GmbH – Germany Fax: +49 2972 9715 11 Email: info@transfluid.de Website: www.tube-processing-machines.com

permit the accurate, rapid separation of components even when they are already assembled with additional components or are going to be assembled. High output in complex production often requires intelligently tuned handling systems that are fast and can ensure that pipe processing machines next to each other can be operated simultaneously. “This should be considered entirely separately from the overall cycle time,” explained Stefanie Flaeper, managing director at transfluid. “The important point is that the main part of a cycle time is available for the processing of parts. Handling isn’t the determining factor for cycle time.” To ensure the ideal utilisation of the processing machines in the production cell, transfluid relies on the newly developed servo- electrically controlled four-axis handling system, which meets

THE fastest way to the best results does not rely on speed alone. The optimum tuning and interplay of different systems is where processes can be made efficient, particularly with powerful automation systems for pipe processing. transfluid Maschinenbau GmbH has developed specially tuned automation systems into efficient standards.
