DEVICE AND METHOD FOR PRODUCING AT LEAST PARTIALLY CLOSED HOLLOW PROFILES WITH ROTATABLE DIE HALVES AND LOW CYCLE TIME |
摘要 |
<p>The invention relates to a device to produce an at least in part closed hollow profile from a board by means of a U-O-forming with a tool comprising at least a U-stamp and at least an upper cavity in a first tool half. At least two identical at least in part U-shaped die cavities are provided in a second tool half. The U-stamp and the upper cavity of the first tool half are each meshed with an at least in part U-shaped cavity when the tool is shut. The at least one U-stamp and the at least one upper cavity of the first tool half and the at least two at least in part U-shaped die cavities of the second tool half are arranged in a rotationally symmetrical manner to the rotational axis running in the closing direction of the tool.</p> |
