摘要： A method using high interior pressure to reshape structural section of continuously bounded overall cross-section, whereby the overall cross-section can be provided with extra walls or chambers and a stopper is forced radially against each end of the piece. The object is to reduce wear on the stopper while ensuring that any walls or chambers in addition to its overall cross section will buckle or bulge only at their ends. Either any walls (2 & 3) that partition the chambers (4, 5, & 6) and any independent wall (7) are provided with slots (17) at the ends of the piece that parallel the inner surface (18) and outer surface of the piece or the stopper (8) itself is provided with grooves (19) adjacent to and matching the shape of the walls.

摘要： The lower part of a material to be molded forms a lower, seal with a die. A punch applying a molding force to the material forms an upper seal with the perimeter of the die. The space between the upper and lower, seals forms a pressure chamber that is filled with a fluid. As the punch descends into the die, the fluid is pressurized. The lower seal is a complete seal to prevent leakage of fluid into the die. The upper seal is given a clearance with the die that permits controlled leakage of fluid therepast at a rate that limits the maximum pressure in the pressure chamber while permitting the development of an adequate pressure on the material being molded.

摘要： Superplastic forming of sheet metal blanks is advanced both is quantity and quality with the utilization of a part separating and pressure distributing mid plate sandwiched between a pair of blanks. This arrangement is loaded between upper and lower die halves operatively mounted in a heated press which closes to effect the piercing of one of the blanks by a nozzle which subsequently delivers pressurized air or other inert gas to an intermediate chamber formed by the mid plate between the blanks to effect the simlayaneously forming of separate parts in both forming dies.

摘要： A method for measuring the plasticity of materials such as ceramic raw materials and masses. A weight acts on a sample body and a path signal that reproduces the deformation of the sample body is measured. During the deformation process, the time progression of a reaction force applied by the sample body is measured. Path and force measurement values are passed to a computer for processing and evaluation. Devices for measuring the plasticity of a material according to the method are also disclosed.

摘要： A hydroforming apparatus includes upper and lower platens that are connected together by tie rods extending through respective compression tubes. An upper die section is carried on the upper platen by a generally C-shaped suspension arm, while a lower die section is carried on the lower platen. The upper and lower die sections have recessed areas formed therein that define a die cavity. Lift assemblies are provided on the lateral ends of the hydroforming apparatus for selectively elevating the lower die section upwardly into engagement with the upper die section. When the lower die section is elevated by the lift assemblies, a workpiece is enclosed within the die cavity. A bolster is then moved between the hydroforming die and the lower platen. A cylinder array containing a plurality of pistons is next hydraulically actuated so as to securely clamp the hydroforming die between the cylinder array and the lower platen. While the cylinder array is actuated, pressurized fluid is supplied within the workpiece, deforming it into conformance with the die cavity.

摘要： In a method and a device for producing a circumferentially closed hollow profile, a hollow-profile blank is expanded by fluidic internal high pressure in an internal high-pressure forming tool, after which the hollow-profile blank assumes the final shape of the hollow profile. In order to make it possible in a simple manner to have a production of a hollow profile in which process reliability is ensured to a sufficient extent even in the case of high expansions of the hollow profile (higher than or equal to the breaking elongation of the material), during expansion, the hollow-profile blank is supported, on at least one partial circumferential region, by at least one diaphragm fastened to the inside, facing the blank, of the tool and capable of being acted upon by a controllable pressure acting from outside, the diaphragm shifting back elastically as expansion progresses, with the supporting pressure acting on the diaphragm being reduced at the same time.

摘要： An apparatus for forming two plates into a hollow workpiece has a pair of dies having edge regions adapted to be pressed together against outer peripheries of the plates. An outer element in the edge region of one of the dies is adapted to rotate therein about an axis generally parallel to the direction and an inner element set in the outer element is rotatable therein about an axis generally parallel to and offset from the outer-element axis. The inner element is formed offset from its axis with an axially throughgoing feed passage aligned with a feed hole in the plate engaging the one die. A fluid forced under pressure through the passage and hole into a space between the plates deforms the plates away from each other in the direction while displacing the hole perpendicular to the direction with movement of the passage perpendicular to the direction.
