DEVICE FOR SHOCK-DEFORMATION OF WORKPIECES

摘要

An explosive performing device comprises a chamber composed of a plurality of walls. Either the top and bottom wall are movable toward and away from one another between a chamber-closing and a chamber-opening position; alternately the top and bottom wall may be stationary and the circumferential wall could be composed of at least two sections which are so movable. The inertia of the movable walls is so selected that it at least substantially equals the shock pressure necessary for producing the energy level required to obtain the deformation of a workpiece into conformance with the surface contour of one or more dies located in the interior of the pressure chamber. An explosive device serves to produce a sudden increase in pressure in the chamber. Energy-consuming connecting means connects those walls which are movable relative to one another and serves to consume shock-pressure energy in excess of the predetermined energy level during the relative movement of the walls from chamber-closing to chamber-opening position.
