摘要： A method of producing a composite component, in which a hollow section is expanded, at least in regions, by internal high pressure. In a first step a region of the hollow section is expanded until it comes to lie against an edge region of a cavity of a combined hydroforming and injection mold. In a second step the cavity is filled with an injection molding compound. In a third step the hollow section, at least in regions, is expanded further, which increases the internal high pressure.

摘要： In a method and apparatus for producing a composite component comprising a hollow profile and at least one injection-molded element, a hollow profile (3) is formed by means of internal high pressure fluid forming and is encapsulated with an injection molding material to form the injection-molded element. The hollow profile is expanded by means of internal high pressure in a closed combination tool comprising an internal high pressure forming tool element and an injection molding tool element, before it is encapsulated. The hollow profile is pressed on the tool engraving only locally in the region of the location to be encapsulated, keeping the outlet of the injection molding channel opening into the tool engraving clear.

摘要： In a method and apparatus for producing a composite component, a tubular hollow section blank is placed into a die cavity of a combination tool comprising an inner high-pressure shaping tool and an injection-molding tool. The combination tool is filled with a fluid in such a way that the blank is wetted from the inside by the fluid, and the ends of the combination tool are sealed by two axial molding plugs. The filled blank is then expanded under pressure . The finished hollow section is plastic-coated in the same tool. The hollow section is emptied after shaping in the sealed state, at least until it is no longer dripping, the pressurized fluid being expelled under pressure from the hollow section through at least one discharge channel formed in the axial molding plugs.

摘要： The invention relates to a method and device (1) for producing a composite component, wherein a tubular, hollow section blank (5) is placed into the die cavity (3) of a combination tool comprising an inner high-pressure shaping tool (2) and an injection-molding tool, the combination tool is filled with a fluid in such a way that the blank (5) is wetted from the inside by the fluid, and the ends of the combination tool are sealed by two axial molding plugs (6 and 7). The filled blank (5) under pressure is then widened. The finished hollow section (22) is then plastic-coated in the same tool. In order to produce the composite component in a relatively simple manner and by a reliable process, it is suggested to empty the hollow section (22) after shaping in the sealed state at least until it is no longer dripping, wherein the pressurized fluid (19) is expelled under pressure from the hollow section (22) through at least one discharge channel formed in the axial molding plugs (6 and 7).

摘要： The invention relates to a device for forming a peripherally closed hollow profiled element (1) by means of fluidic internal high pressure. The device contains an axial plug (4) for sealing off the hollow profiled element (1) on the end face, said axial plug possessing an axial passage duct (5) supplying pressure fluid. The axial plug (4) has a sealing body which possesses on its end face (19) a trough-like depression (20), the peripheral wall (21) of which can be spread open radially elastically, within the hollow profiled element (1), by means of pressure fluid, until said wall comes to bear sealingly against the inner wall (22) of the hollow profiled element (1). To maintain the sealability of the device permanently, the axial plug (4) is to have a plug head (8), formed by an annular collar (10) and a narrowed extension (11) adjoining the latter toward the end face (7) of the head (8), and, on its plug body (9), a radial peripheral stop for bearing against the closing edge (12) of the hollowed profiled element end (13). The sealing body, designed as a sealing ring (17), is fixed on the extension (11), the margin (28) of the annular collar (10) projecting peripherally beyond the outside (27) of the sealing ring (17) at least one point in the radial direction.

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： The invention relates to a forming die having a cavity which forms a shaping space and into which a workpiece can be introduced. A passage, which connects the shaping space to the area surrounding the die, runs within the forming die. To achieve a contour during the shaping of the workpiece which is unaffected by the arrangement of passages connecting the shaping space to the area surrounding the die in a simple way, it is proposed that the die contains a liquid-permeable and gas-permeable insert body, which is held in a recess of the die near to the shaping space and by means of a peripheral region facing the shaping space forms a section of the cavity, and that the passage opens out at the insert body outside this peripheral region.
