Focused and diverse range of bending and forming for hydraulics

the MB 642 can bend tubes within a diameter range of 6 to 42mm. The bending radius can be relatively tight – between 2 and 2.5x the diameter of the tube, or 3x for very thin-walled tubes. Available extra equip- ment includes internal and external de-burring devices, saws and

THE highly dynamic stress on hydraulics tubing and connections requires technology that delivers clean, robust and long-term results. Engineering company transfluid has been developing tube bending machines for 30 years to produce these results, and the solutions for these demanding specifications are increasingly advanced, from simple bending machines that bend directly on the equipment to CNC- controlled bending machines. Cutting ring pre-assembly machines are available for connections in hydraulics and also forming machines, to add DKOL and other soft sealing connections and hose fittings directly on the tube, as well as forming a single-piece tube fitting on the tube, with no chips. transfluid has developed the latest generation of its classic mobile bending machine t bend MB 642 for bending directly on-site. With this machine it is possible to bend tube up to 6m long; the floor space needed by the machine does not change, because the rotating head can turn, reducing the working space needed to a minimum. With the compression bending technique,

Bending machines with mandrels and fully hydraulic control can be equipped with units to assemble cutting rings, for flaring, de-burring, cutting and bevelling

assembly devices for the most common connection systems (flange and with cutting ring for thread cutting), as well as metal circular saws. For the manufacturing of tube geometries for individual pieces or small series with rotary draw bending, transfluid has developed compact bending machines with mandrels. They are flexible and can achieve a tight bending radius, even with tubes with thin walls, when bending with a mandrel. The t bend DB 2076K machine can work with tubes with a diameter of 20 to 76mm. It is possible to transfer data to the machine with a USB connection; the control system can store whole bending programs and the machine comes with an eight-angle pre-selection as standard. Optional equipment such as saws, burr- ing devices and cutting ring for threads and flanges allow the manufacture of complete tubing systems. As well as tubing and connections for hydraulic applications, there is often a need to process CAD data from different programs or to manufacture complex tubing systems. transfluid makes this possible with CNC machines that are simple to use and completely automated. The tools can be exchanged quickly, making their use very flexible. They are suitable for small produc- tion runs and for applications with high geometry diversity. The bending ma-

chines work independent of the user and to the specifications of the indi- vidual project, thanks to the interfaces available to connect them with CAD and measuring machines. The two versions of transfluid’s own t project software provide controlled tube manufacturing and connect the machines to CAD and measuring systems, manufacturing execution systems or ERP systems. It is possible to test bending sequences in advance, to make sure that there are no collisions. Various additional modules contain the information for whole sequences, to have better control over the process and to manage the forming process data. The software also helps at the cutting stage, reducing any waste to a minimum. transfluid also offers separate assembly machines for cutting ring or flange connections. They operate in an axial or rolling manner to deliver safe connections. The combination desk unit HA 642 makes it possible to have the die ring pre-assembly and the flanging of tubes with a 6 to 42mm diameter. transfluid Maschinenbau GmbH – Germany Fax: +49 2972 9715 11
