摘要： A machine for compacting metal powder comprises a static frame, a die having a bore, a lower punch defining a receiving die cavity in the bore, an upper punch, an upper punch downwardly movable to enter the die cavity, and a reaction frame to which the lower punch is fixed slidably mounted on the static frame, the reaction frame and the lower punch being moved upwardly by a reaction force generated when the upper punch is moved downwardly. The die is moved upwardly after the die cavity has been filled with powder a distance at least equal to the upward movement of the lower punch completed before the upper punch enters the die cavity, and the die is moved downwardly after the upper punch has entered the die cavity.

摘要： A TOOL FOR A HIGH ENERGY RATE MACHINE FOR THE PRODUCTION OF COMPACTS OF METAL POWDERS OF TWO OR MORE SECTIONS OF DIFFERENT THICKNESS IN LINE OF PRESSURE COMPRISES AN UPPER PUNCH FIXED TO A RECIPROCAL MACHINE RAM, A DIE HAVING A BORE DEFINING THE PERIPHERY OF THE CAMPACT TO BE PRODUCED, A FIXED LOWER PUNCH AND A MOVABLE FLANGE PUNCH DISPOSED WITHIN THE BORE AND FORMING TOGETHER A LOWER CLOSURE FOR THE BORE, A FLANGE PUNCH PISTON FIXED TO THE FLANGE PUNCH HAVING UPWARDLY AND DOWNWARDLY FACING SURFACE, MEANS FOR SUPPLYING FLUID PRESSURE TO THE DOWNWARDLY FACING SURFACE TO HOLD THE FLANGE PUNCH IN AN UPPER POSITION PRIOR TO COMPACTION OF POWDER CONTAINED WITHIN THE DIE, AND MEANS FOR SUPPLYING FLUID PRESSURE TO THE UPWARDLY FACING SURFACE TO MOVE THE FLANGE PUNCH PISTON DOWNWARDLY DURING COMPACTION OF THE POWDER BY THE UPPER PUNCH.
