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 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.

摘要： A tube bend has at least one bend zone and two outlet zones adjoining the latter on both sides. The tube bend has a different cross-sectional shape from the outlet zones with an identical flow cross section. The degree of expansion, as the ratio of the diameter of the component in the bending plane to the diameter of the blank in the bending plane, has a value between 1 and 1.1.

摘要： A process is for producing a circumferentially closed hollow profile, which is of frustoconical form in sections, from a sheet-bar blank. To produce hollow profiles of this type, the sheet bar is cut to size so that a blank with a rectangular section and a ring segment, the summit of which adjoins the center of one side of the rectangle, while its outer arc, which faces the rectangle, is of approximately the same length as the length of the side of the rectangle, is formed, sheet-bar material also being left on the blank outside the summit, between the ring segment and the side of the rectangle, this material joining the ring segment with the side of the rectangle integrally at all locations and also joining the corners of ring segment and rectangle which are closest together, so as to form a rounded edge contour. Then the side edges of the blank are bent into abutment with one another about the longitudinal center axis of the blank. After the bending operation, the edges of the sheet-bar blank are joined together by a longitudinal seam weld, so as to form a preform of the hollow profile, which is then deformed into the final form by internal high-pressure fluid.

摘要： A method is provided for producing peripherally closed hollow profile section using fluidic internal high pressure. A hollow profile section blank is inserted into a cavity of an internal high pressure forming tool and thereafter being pressed mechanically into an intermediate form approximate to the final form of the hollow profile section, after which, with the tool closed, the intermediate form of the blank is expanded into the final form of the hollow profile section. The blank used in terms of its peripheral length, possesses oversize with respect to the peripheral length of the forming tool cavity. Moreover, the blank material which is excess with respect to the blank material required for the hollow profile section blank to come to bear completely against the cavity of the forming tool is pushed into the blank interior, so as to form an indentation, at the earliest during the pressing operation.
