摘要： The subject matter of the present invention is a method of manufacturing, in a tool mold provided with a final contour as desired, a hollow metal body the cross-sectional shape of which varies in the longitudinal direction, an internal pressure being applied to a tubular hollow body with approximately uniform initial wall thickness, the tubular hollow body having the highest temperature in the zones of greatest deformation, the temperature in these zones being reduced once the hollow body fits against the wall of the tool mold, the temperature being subsequently increased in zones with lower degrees of deformation.

摘要： In order to produce a metal bellows of a length of “Ls” for use in a heated atmosphere, the following steps take place. First, a blank of the bellows is prepared, which is a metal pipe having a plurality of bulges formed therearound. The blank has a length of “L” that is longer than the length “Ls”. Then, the blank is axially compressed by a length of “a”, so that the compressed blank has a length of “L−a” that is shorter than the length “Ls”. Then, the compressed blank is axially expanded so that the expanded blank has a length of “L−a+b” that is longer than the length “Ls”. Then, the force that has been applied to the blank is removed, and then the treated blank is left in room temperature until the time when the treated blank becomes to have the length of “Ls” due to the spring-back phenomenon.

摘要： Sliding plugs use o-ring seals against the internal walls of an isostatic bulge forming die to apply end load to tube stock blanks during isostatic bulge forming. The die is made from two or more mating segments that assemble together to define a central channel for holding the tube stock blank. The plugs move inwardly into the die when the blank elongates or expands into the die, because such expansion reduces the internal pressure within the blank. The plugs are drawn inwardly because of the pressure decline in the blank. The plugs compress the ends of the blank and force the ends inwardly closer together. Such motion effectively feeds more material to the die and permits greater elongation in the completed part with tighter corner radii. Motion limiting shoulders on the plugs assure that the feeding of material is even from both ends. Typical range of motion for a plug is about 0.5 inches.

摘要： The invention relates to a method for producing or machining a work piece in the form of a cylindrical hollow body, especially a container (an outer wall of a container), a barrel or a cask. According to the inventive method, the work piece is held so that the longitudinal axis thereof is oriented vertically and is then machined, especially formed, edged and provided with beads, a bottom and a lid. The method is characterised in that the work piece is moved at the transfer level and is lowered into a working area of a machining device, especially a shaping machine, for machining. The machining device is arranged underneath the transfer level.
