摘要： A super-plastic forming tool for forming aluminum sheets is provided that includes a seal bead that is configured to facilitate removal of the aluminum sheet from the seal bead after a super-plastic forming operation. Contraction of the aluminum sheet at a faster rate than the super-plastic forming tool facilitates removal of the aluminum sheet due to the specific geometry of the seal bead. The seal bead has a more shallowly sloped outer surface than its inner surface and may be provided in different configurations including flat, convex, concave shapes.

摘要： The present invention relates to a method for producing components from a blank (P1-P4) made of a deep-drawable material, particularly steel using a free-flowing action medium. In the course of this method, the blank (P1-P4) is clamped in a forming device (U1, U2) and an action medium is applied to it. The blank (P1-P4) is then preformed by elevating the pressure (P) exercised by the action medium in a region of the blank (P1-P4) which is restricted to a section (V1, V2) of the blank surface and which partially covers the surface section (B1, B2) of the blank (P1-P4) from which the final form of the component is generated. Subsequently, the preformed blank (P1-P4) is finish formed using a forming tool (F1, F2). In this way, components having complex shapes may be produced with optimum exploitation of the properties of the material used.

摘要： A coating for superplastic forming (SPF) and quick plastic forming (QPF) tooling and an SPF/QPF process made possible with the coating. The coating defines the forming surface of an SPF/QPF tool, and consists essentially of either a tungsten carbide cermet or a chromium carbide cermet. The coating preferably comprises a metal matrix containing tungsten carbide or chromium carbide particles having a particle size of not more than 0.1 micrometer, and is preferably prepared to have a surface finish of not rougher than 0.3 micrometer Ra. An SPF/QPF process that makes use of a tool whose forming surface is provided with the coating can be performed without depositing any lubricant on the forming surface or workpiece.

摘要： Superplastic forming tools and method in which pairs of stacked metal blanks are serially loaded between heated forming dies that are moved to a closed position on each of the pair of blanks so that a partial perimeter gas seal is established therebetween. A pressure wedge is then introduced between the two blanks along one edge of the pair to act as a stopper or air seal to complete perimeter sealing thereof. The pressure wedge also establishes the operative position of a gas injection port, which directs pressurized air interiorly of the completed perimeter seal of the pair of blanks to force the blanks in opposite direction for the superplastic forming of a pair of discrete parts. The wedge and forming dies are then opened for the removal of a pair of formed parts and for the subsequent loading of additional pairs of stacked sheets for their simultaneous superplastic forming into pairs of parts. With this construction and process, the output of superplastic forming equipment can be multiplied for improved efficiency and for improved formation of parts.

摘要： A hydroforming apparatus includes an upper platen carrying an upper die section and a lower platen carrying a lower die section. The platens are connected together by tie rods extending through respective compression tubes. The upper and lower die sections have recessed areas formed therein that define a die cavity. When the lower die section is moved to a lowered position, a workpiece can be disposed in the recessed area formed therein. Then, the lower die section and the workpiece are elevated by cylinders such that the workpiece is enclosed within the die cavity and mechanically deformed by the cooperated upper and lower die sections. A support block 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： The invention relates to a hydroforming device and a hydroforming process and also to a hydroforming die arrangement. To make it possible to produce even complex three-dimensional sheet-metal shapes while ensuring that the deformation process takes place without disruption, the device comprises a die (5) which is divided into two die halves (5a, 5b) along a die parting plane, the two die halves (5a, 5b) forming at least one forming chamber (6) which can be acted on by a hydrostatic internal pressure (Pi) for forming purposes at a workpiece (7) which is to be deformed, a die carrier (2), which for each die half (5a, 5b) has at least one die carrier component (3, 4) assigned to this die half (5a, 5b), each pair made up of die carrier component (3, 4) and die half (5a, 5b) being assigned at least one fluid chamber (8) which is formed from a piston component and a piston-receiving component, and means being provided for producing a hydrostatic fluid chamber pressure (Pa) which is at least equal to the hydrostatic internal pressure (Pi) and, compensating for the hydrostatic internal pressure (Pi), exerts a die-closing force on the two die halves (5a, 5b).

摘要： A method for hot hydrostatic pressing by means of working liquid which tends to become unstable within a transition time when in contact with a blank heated to a high working temperature and at a pressure lower than the liquid's stabilization pressure. The pressing of the blank heated to the high working temperature is carried out by raising the pressure of the working fluid to said stabilization pressure for a time shorter than the transition time. This is achieved by surrounding the heated blank by a cover adapted to delay the contact between the heated blank and the working liquid until the pressure in the working chamber is raised.

摘要： Apparatus for sealing an end portion of a tubular workpiece in a mold for internal high-pressure forming of the workpiece, includes a housing having a pressure compartment in fluid communication with an interior space of the workpiece. Hydraulic high-pressure fluid is supplied from a pressure source to the pressure compartment by a pressure application unit which further includes a pressure piston received in the pressure compartment and defined in the pressure compartment by an effective piston area which is greater than a cross sectional area in the interior space of an end portion of the workpiece. At least indirectly connected to the pressure piston is a sealing mandrel which interacts with the end portion of the tubular workpiece. A check valve is disposed in a passageway between the pressure compartment and the interior space of the workpiece for blocking in a direction to the pressure compartment.
