| Abstract Scope |
The design of the strip layout and especially the stretch web geometry in progressive die stamping has so far been predominantly experience-based aiming for material utilization and cost optimization. Disruptive vibrations of the highly dynamic transportation of the strip can lead to reduced part quality and at worst to a component collision and a damage of the tooling. Therefore, the stroke rate and the output quantity often need to be reduced. A physical model is developed, which describes the stiffness and damping properties of the stretch web, taking the requirements of the progressive die stamping process into account. These properties are material- and geometry-dependent and are determined by a finite element model, which is validated by experimental tensile and acoustic impact testing. Based on the most common stretch web shapes found in industrial application, a study of the geometrical parameters influence on the stiffness is conducted to reduce strip vibrations. |
