The Methodology and its Determination of the Springback in Stamping Processes of Outer Car Body Parts

Popis výsledku v původním jazyce

In the stamping process, springback causes geometrical inaccuracies in the final shape of metal stampings. Springback behavior is highly influenced by mechanical properties of the material, by the geometrical complexity of the shape and also by stamping process itself. To eliminate springback problem in stamping production there are methods, discovered and approved by advanced procedures. However applying these methods, particularly in drawing operations is much more complicated. The research describes theoretical analysis of springback phenomenon and possible experiments for the springback compensation. This research focuses on the creation and application of the springback compensation strategy with the goal of minimalize the springback phenomenon in the field of stamping processes. Especially in automotive where springback became an often debatable and significant topic. For the verification of the strategy, car body parts from VW Group were used. Proposed strategy was designed in the cooperation with the Pressing tools design department in ŠKODA AUTO
