摘要： This invention is a structure and process of truing piston cylinders. The structure consists of a main mandrel support means to hold a mandrel member therein including (1) a support base means; (2) a piston cylinder support means mounted on the support base means; and (3) a power supply means connected to the support base means and the piston cylinder support means. The piston cylinder support means includes a stationary headstock and a movable tailstock, both supported on the support base means. The stationary headstock and the movable tailstock are operable to hold a piston cylinder to be trued therebetween plus each having a mandrel receiving member. The power supply means is operable to supply fluid under pressure to the stationary headstock and return fluid to a reservoir tank through the movable tailstock. The mandrel member resembles a miniature barrel member having a main body member; a plurality of spaced sizing ring sections about the main body member; a central fluid channel in the main body member and a plurality of fluid bleed holes leading from the central fluid channel to areas between the sizing ring sections. The diameters of the sizing ring sections progressively diminish from the center to outer ends. The pressure fluid is forced through the main channel and the fluid bleed holes to force the mandrel member the length of the piston cylinder to achieve accurate sizing thereof to a desired constant diameter.The process of truing piston cylinders consists of the steps of (1) holding a piston cylinder to be trued at opposite ends in a fluid sealed manner; (2) placing a mandrel member at one end of the piston cylinder; (3) applying fluid pressure to one of the mandrel member; (4) moving the mandrel member longitudinally of the piston cylinder; and (5) expanding the diameter of the piston cylinder to maximum diameter of the mandrel member.

摘要： A method and apparatus for forming dental matrices and copings is disclosed. The apparatus provides a first and a second compression member, each of which is provided with a pliable surface thereon. One of the compression members has a point for the attachment of a conventionally formed tooth die thereto, upon which a sheet of conventional coping material can be placed. The compression members are attachable to a jacking apparatus which imparts relative motion to the two compression members urging them together and compressing the tooth die therebetween the sheet of coping material conforming to the shape of the tooth die itself. In the method of the present invention, the first and second compression members are placed a distance apart, and the tooth die attached to one of the compression members at its pliable surface. The sheet of coping material is then loosely attached to the tooth die, after which the first and second compression members are urged together and compressed so as to cause the pliable surface of each compression member to substantially conform to and abutt the tooth die, putting substantially uniform pressure thereon. The sheet of coping material then substantially conforms to the tooth die forming the desired coping.

摘要： Improved internal tooling for a swaging apparatus for attaching fittings to tubing. The tooling includes a draw bolt having a head at one end adapted to be connected to actuating means such as a hydraulic cylinder at its opposite end. A straight cylindrical resilient expander sleeve is coaxially disposed on the draw bolt and is bracketed by a pair of split, circular, anti-extrusion rings located in mating seats formed in facing end surfaces of the draw bolt head and a seal bushing. The facing surfaces of the head and bushing are further configured to include a ramp surface extending between the surface of the draw bolt and split ring seats.

摘要： A press for hydrostatic extrusion includes a pressure chamber for enclosing a pressure medium which is formed of a high pressure cylinder, a pressure generating piston, a die and a die support and seals. The die support includes an exchangeable support ring which engages the end surface of the liner and bridges the gap between the liner and the die. A metallic sealing ring is arranged within the liner in engagement therewith, forming a gap between the inner surface of the sealing ring and the outer surface of the die or die support. The die support has a groove in its upper surface which contains a sealing member against which the edge of the metallic sealing ring engages. The lower outer corner of the metallic sealing ring is bevelled to form a space which communicates with the outside of the press.

摘要： A method and machine for use in hydrostatic extrusion wherein a portion of an elastic-plastic viscous pressure medium is introduced into the rear portion of a container, with the rear end thereof being sealed in a fluid tight fashion. The pressure medium being of such a nature that it has a high viscosity and cannot flow by itself. Subsequently, a billet is charged into the container and then a die is mounted in the container at the forward end thereof. The aforesaid pressure medium is caused to fill around the outer circumferential surface of the billet. In this respect, a high pressure seal is provided for the junctions between the die and the forward end of the container and between the die and the forward end of the billet before the pressure medium flows out of the container in a practically negligible small amount, immediately after which a pressure stem is pushed into the container from the rear end thereof, thus proceeding with the hydrostatic extrusion.

摘要： A tubular can body comprising a radially expanded central portion, a neck at each end of the central portion, and a radially extending flange adjacent each neck at the ends of the tubular member. A tubular, elastomeric member is positioned within a die-contained can body and is pressurized to mold the can body to the shape of the die. The operation forms a radially expanded can body, necks the can body adjacent the radially expanded portion, and flanges the ends of the body in a single operation. A tapered elastomeric mandrel may be utilized in place of the tubular mandrel, obviating the necessity of lubricating the mandrel and allowing the body to be axially extended so that the material from which the can is formed is altered in cross section both radially and axially. A structural groove, suitably positioned in the mandrel surface allows flanging to be effected at the upper end of the can body without damage to the mandrel. Alternatively, an expandable member may be substituted in place of either the tubular or tapered mandrel to form the can body through use of hydraulic pressure.

摘要： A sheet cladding is closely preformed to a convex-concave substrate by a method including the steps of rough forming the sheet cladding about the substrate so that the sheet cladding closely abuts the convex surface of the substrate while being spaced from the concave surface of the substrate. The sheet cladding, assembled to the substrate, is placed into a rubbery mold which is thereafter sealed and cold isostatic pressure is applied thereto so that the portion of the cladding sheet opposite the concave surface is deformed into the concave surface thereby stretching the sheet cladding to form a tight skin over the substrate.
