Large sheet metal parts with low drawing depths usually reveal only low work hardening levels in the central area of the components. As a result, such parts often do not meet specified property requirements. Short-cycle stretch technology (SCS) represents a novel forming process for combined stretching and deep drawing, which allows high-quality production of such large sheet metal parts with improved mechanical properties. Due to a consistently simple tool design with changeable die inserts, SCS technology additionally offers a cost-effective and relatively flexible alternative to currently known processes for combined stretch forming and deep drawing. This paper defines the basic principle and presents close-to-production tool concepts of the newly developed SCS process. Furthermore, the high energy saving potential of the novel forming technology is illustrated in comparison to conventional deep drawing.
