The Tube+ machine offers partial thickening of the walls of a thin-walled blank. The Tube+ process of the same name developed by Felss enables an increase in wall thickness through a cold forming process, and thus the greatest possible component accuracy. Tube+ is an alternative to heat forming. Greater measurement accuracy can be achieved in comparison with heat forming, and process steps, blank costs, and cycle times can often be saved. Thus, despite the high degree of forming, a heat supply and large forming presses can often be dispensed with. Together with the saving of process steps, Tube+ in this way ensures an increase in economic efficiency. The Tube+ machine is currently a prototype in a horizontal version and produces tubes thickened on one side as preliminary stages for pitman arm shafts. In future, the machine will be available according to the module principle for various market segments with customer-oriented products. This means that it will also be possible in future to manufacture drive shafts with both ends thickened using our Tube+ process.
- Higher forming degrees possible
- Increased stabilization of the complete component
- Saving of process steps
- Short process times
- Lower blank costs
- Calibration of the complete component (also in the nonthickened area)
Rotary swaging is suitable for forming the most varied outer and inner geometries. In this case, several tool segments impact on a workpiece repetitively in quick succession. The material begins to flow and is formed with great precision.
In the case of axial forming, a toothed matrix presses the external toothing onto a hollow or solid workpiece. The forming is thereby highly precise. The manufacture of internal tooth splines is also possible in this way.
In the case of ends processing, the most varied flange forms are applied to the tube ends. The tube ends processing procedure is based on the fact that the workpiece is fixed and the tool moves around the component.
Both tubes and flat plates are produced with the Felss bending procedure, whereby the complete process is decisive. The Felss Group offers turnkey system solutions that interlink perfectly and eliminate manual work.
Felss transfer systems stand for the optimal interlinking of various technologies for complex tube geometries. This interlinking of various processing steps makes it possible to produce ready-to-install, complex components in only one run.
