Apparatus for forming metals by means of jet liquid

Abstract

Abstract A METHOD OF FORMING METAL USING AMOLD CAVITY MEMBER COMPRISES PLACING THE METAL IN ASSOCIATION WITH THE CAVITY MEMBER IN A POSITION SUCH THAT IT CAN BE DEFORMED INTO THE CAVITY THEREOF AND DIRECTING A LIQUID FIRST THROUGH A NARROWING PASSAGE TO INCREASE THE VELOCITY AND IMPACT FORCE AND THEREAFTER DIRECTING THE LIQUID AT HIGH IMPACT FORCE AND VELOCITY AGAINST THE METAL TO SHAPE IT INTO THE FORM OF THE MOLD CAVITY. THE APPARATUS FOR CARRYING OUT THE INVENTION INCLUDES A LIQUID PRESSURE CHAMBER AND A PLUNGER WHICH IS SLIDABLE IN THE CHAMBER BUT WHICH IS EXPOSED AT THE EXTERIOR OF THE CHAMBER TO PERMIT IT TO BE MOVED RAPIDLY BY STRIKING IT. THE MOVEMENT OF THE PLUNGER CAUSES THE DISPLACEMENT OF THE LIQUID IN THE CHAMBER THROUGH A NARROWING PASSAGE TO INCREASE ITS VELOCITY AND IMPACT FORCE. THE CHAMBER FOR GENERATING THE HIGH IMPACT FORCE OF THE LIQUID AND INCREASED VELOCITY OF THE LIQUID IS LOCATED ADJACENT A MOLD CAVITY MEMBER SO THAT THE LIQUID MIGHT BE INJECTED INTO THE MOLD CAVITY MEMBER TO DEFORM THE METAL TO BE FORMED. VARIOUS EMBODIMENTS FOR INCREASING THE VELOCITY OF THE LIQUID AND ITS IMPACT FORCE ARE DISCLOSED INCLUDING A SINGLE NARROWING PASSAGE AND A DOUBLE PASSAGE CONSTRUCTION, AS WELL AS A DIVERGENT PASSAGE CONSTRUCTION.
