Using a process of the same name, the Felss Tube+ machine enables a partial increase in the wall thickness of tubes through a cold forming process, and thus the greatest possible component accuracy.
Tube thickening to reduce process steps
The Tube+ machine offers partial thickening of the walls of a thin-walled blank. The Tube+ process developed by Felss uses a cold forming process to increase wall thickness and thus ensure the greatest possible component accuracy.
Applications of Tube+
Tube+ is an alternative to heat forming. A greater dimensional accuracy can be achieved compared to heat forming, and process steps, blank costs, and cycle times can often be reduced. This means that a heat supply and large forming presses often become unnecessary, despite the high degrees of deformation. Together with the fewer number of process steps, Tube+ increases economic efficiency.
The Tube+ machine is currently a prototype in a horizontal orientation and produces tubes thickened on one side as preliminary stages for steering shafts. In the future, a modular version of the machine will be available for various market segments with customer-oriented products. This means that it will also be possible to manufacture drive shafts with both ends thickened using our Tube+ process in future.
Advantages of the Tube+ machine
Higher degrees of deformation possible
Increased stability of the processed component
Fewer number of process steps
Short process times
Lower cost of blanks
Calibration of the complete component (including the non-thickened area)
