Trumpf continous emboss/bead/rib will cause sheet metal distortion, More distortion increase as longer or more wide.
Normally this type tooling without spring inside and alignment ring
Unlike a standard punching tool that performs its forming function in a single stroke, the continuous bead tooling operates by way of a rolling process.
Mechanism: The tool consists of a set of rollers (a punch roller and a die roller) between which the sheet metal is continuously fed.
Contour Creation: The tool performs the forming through a continuous motion of the machine table. The sheet travels between the rollers, which plastically shape the material as it is pulled through.
Flexibility: This high processing speed rolling concept allows for the creation of any length of contour and shape (straight or curved) in a single non-interrupting work step.
Key Features and Applications
The primary objective of this tooling is to introduce stiffening forms into thin-walled sheet metal components, often referred to as longitudinal beading or stepping.
Material Cost Reduction: By adding these structural stiffeners or reinforcing beads, manufacturers can reduce the required material thickness, thereby achieving lower material costs without compromising the component's structural integrity or stability.
Optimal Quality: The rolling method ensures beads without visible forming marks or scoring, achieving a highly uniform and optimal quality surface finish.
Design Freedom: Because the bead length is not restricted by the tool's dimensions but by the machine's travel, the tool offers maximum flexibility in design, accommodating both straight as well as curved beading.
Process Efficiency: The combination of continuous forming and high processing speed makes it a particularly cost-effective production method for these elongated features, minimizing production costs.
