Bending systems 7000 and 9000

The cost-effective bending machine for narrow bending radii

For tube dimensions of 20 mm to 90 mm this bending system offers solutions for complex geometries with standard radii of 2xD. Depending on material quality and wall thickness ratio also radii of 1.5xD can be realised suitable for series production. At a tool height of 120 mm there are also sufficient possibilities for special profiles.

The extremely precise and strong electric drive of the bending axis and the stable and rigid construction of the mandrel support and the bending arm contribute also to the desired bending result.

The pluggable bending tools enable quick retrofitting for bending other tube dimensions. The locking clamp pressure for tube clamping can be optimally adjusted. The SPS control with data storage and latest X2X interface can store over 1000 programs (can be expanded via USB stick) for bending angle, linear measure and torsion angle for a maximum of 50 bending sequences at one tube length. A freely programmable database up to 500 of materials is available for monitoring the elastic recovery values.

The machine disposes of two operational modes: In “simple bending” length and torsion of the bends towards each other are automatically displayed. In the mode “controlled bending” the data is stored beforehand and a permanent nominal/actual comparison is made during bending.

Also available with pneumatic rotation stopper or with gear-assisted length and twist positioning.
