Abstract
Methods and apparatus are disclosed for consolidating loose or pre-compressed particulate materials, such as metal powder or metal flakes, in press equipment utilizing a reusable canister means that is sealed in vacuum from the atmosphere and heated prior to consolidation in the press equipment at elevated pressures and temperatures, thereby improving utilization of the press equipment.
Claims7
Apparatus for use in consolidating particulate materials into useful product at elevated temperatures and pressures in press equipment having a movable ram, a fixed support bed, and an internally tapered receiver means surface, aligned with said movable ram and supported by said support bed, comprising:
- a. a tubular canister body having a tapered external surface that corresponds to the tapered surface of the press receiver means and an internal cross section corresponding substantially to the cross section of the press ram;
- b. removable sealing closure means closing the lower interior of said canister body;
- c. removable shear sealing closure means closing the upper interior of said canister body, said shear sealing closure means being sheared as it is moved by said movable ram into said canister body;
- and
- d. valved vacuum exhaust line means communicating with the interior of said canister body intermediate said removable sealing closure means and said removable shear sealing closure means.
Apparatus for use in consolidating particulate materials into useful product at elevated temperatures and pressures in press equipment that cooperates with tubular canister bodies, each having
- (a) a tapered external surface that corresponds to the tapered surface of a press receiver means,
- (b) removable sealing closure means closing the lower interior of the canister body,
- (c) removable shear sealing closure means closing the upper interior of the canister body, said shear sealing closure means being sheared as it is moved by a movable press ram into the canister body;
- and
- (d) valved vacuum exhaust line means communicating with the interior of the canister body,
- which are operable interchangeably within the press equipment and which are connectable to heating means and outgassing means in a station removed from the press equipment;
- the station being operable to load the canister bodies, heat the canister bodies, and outgas the canister bodies, apart from and preliminary to the transport of the canister bodies to the press equipment for shearing of the upper shear sealing closure means and subsequent consolidation of the particulate materials.
