Abstract
Short-Cycle-Stretch-Forming (SCS) combines stretch forming and deep drawing within one stroke. Conventional blankholder is replaced by a set of beads around the part. The beads are pre-stretching the material to enhance dent resistance and increase material strength while thinning the material at the same time. Pre-stretching is followed by the deep drawing. In this stage bead set functions as a blankholder. The amount of retaining force and pre-stretching can be adjustet by varying bead design and surface conditions. SCS technology allows reduction of tool size and required press force and size and will thus function as flexible tool system of the future.
