Roller bending of small diameter tubes
Roundness: 0.2 - 0.3 mm Material thickness: 1 up to 2 mm Tube length: 50 up to 750 mm
The existing portfolio of roller bending technology from 2-roll and multi-roll round bending machines of weil technology has been extended by another module: Tubes with smaller diameters and high-precision roundness can now be manufactured.
• Tubes Ø 30 with roundness 0.2 - 0.3 mm
• No flat zones
• Material thickness 1.0 - 2.0 mm
In order to produce electric motors, spacer sleeves or bushings, nothing more than the replacement of the winding mandrel of the RMA+ is required to continue manufacturing 10 minutes later.
Cycle time: 6 - 12 parts / minute
Diameter change approx. 10 minutes
The tubes are automatically clamped and welded in a laser welding machine in the subsequent welding process.
Calibration is required for even lower run-out tolerances and depending on the pipe length, a tolerance of 0.1 mm to 0.15 mm can be achieved.
