Abstract
An isostatic press comprises a pressure vessel defined by a tubular jacket and by two end plugs. The jacket is, in the direction of its longitudinal axis, displaceble between two positions. The jacket surrounds a third plug centrally located between the two positions of the jacket so that, when the jacket is in one of its end positions, the central plug closes one end of the jacket, and vice versa. The two jacket positions alternatingly serve as pressing and charging positions so as to permit recharging of the press at one position simultaneously with carrying out a pressing operation at the other position. This arrangement approximately doubles the productivity of the press.
Claims15
An isostatic press, comprising
- frame means (3);
- a tubular jacket (10) slidably mounted to said frame means (3), said jacket (10) having end apertures and being longitudinally displaceable at least between two end positions on said frame means;
- at least three plugs (11,12,13) mounted to said frame means (3), two of said plugs (12,13) being at respective ends of the travel of said jacket (10) and the remaining plug (11) being intermediate said ends;
- the end apertures of said jacket (10), when said jacket (10) is in each of its end positions, being engaged and closed by one of said two end plugs (12,13) and by an intermediate plug (11) so as to form a pressurizing vessel with said engaged plugs, whereby the side of said frame means which is free of said jacket (10) may be charged in preparation for a pressurizing operation thereat.
