Vorrichtung zur Hochleistungsumformung von Werkstuecken,insbesondere aus Blech,mit Hilfe von Schockwirkungsmitteln

摘要

An explosive-forming device has walls surrounding a pressure chamber arranged to accommodate a workpiece and a die whose surface contour is to be imparted to the workpiece for shock-deformation of the latter into conformance with the surface contour. A recess is provided in the wall means and has an opening communicating with the pressure chamber. A gunpowder charge is accommodated in the recess and fills the same partly. Damping means is arranged in the remainder of the recess intermediate the charge and the opening of the recess and fills at least a part of this remainder of the recess.
