Abstract

An apparatus for the hydroplastic deformation of tubular blanks, comprising a housing, a front stop member and a back stop member in line within the housing, the back stop member being of hollow construction defining, in turn, towards the open, forward end thereof an explosion chamber, a guiding chamber and a compensating chamber and housing a working tool, said chambers intercommunicating, the guiding chamber providing a rest position for the working tool and the working tool being formed with a forwardly extending blind bore and with at least one radially extending duct connecting the blind bore with its exterior and carrying as its forward end a sealing element; and the front stop member housing a fixed ram and a travelling cylindrical piston in whose central passage a tubular blank is to be positioned, in use, which travelling piston has one end positioned over the fixed ram for sliding travel thereover and to define a recoil chamber therebetween, longitudinally extending duct means in the travelling cylindrical piston communicating the recoil chamber with the compensating chamber.
