摘要： A device for punching work pieces in an internal high-pressure forming tool includes a punching die guided displaceably in a bore of the forming tool. The device also contains a drive with which the punching die is moved back and forth between the in-use position and the non-use position. In order to facilitate, in a simple and space-saving manner, the punching of work pieces in the internal high-pressure forming tool, the drive contains a pressure fluid and a pressure transfer device that can be elastically expanded via the pressure fluid between a base firmly attached to the tool and a punch head of the punching die. The pressure transfer device abuts a partition at least indirectly at the punch head.

摘要： In a method and apparatus for producing a peripherally closed hollow profile having a secondary feature and/or a branch, the hollow profile is shaped from a hollow profile blank by an internal high pressure. The cap of the secondary feature and/or of the branch is severed by a counterholding punch that supports the secondary feature or the branch during the shaping process. In order to permit the production of a hollow profile having secondary features and/or branches, during which the cap of the secondary feature or of the branch is severed in a simple and reliable manner in terms of the process, the cap of the secondary feature and/or of the branch is severed at an internal high pressure which corresponds at most to the forming pressure for forming the hollow profile from the blank.

摘要： The invention relates to a method and a device for reinforcing a hollow section (1, 24) having a closed periphery, an opening (2) being produced at its periphery, after which a reinforcing component introduced into the hollow section interior (8, 25) is joined to the hollow section wall (11, 27) opposite the opening (2). In order to reinforce the hollow section (1, 24) as easily as possible, it is proposed that, at the location of the opening (2) to be produced, a wall piece (7, 23), forming the reinforcing component, of the hollow section (1, 24) be cut out except for a peripheral region, that the wall piece (7, 32) hanging in one piece on the opening edge (9) be bent into the hollow section (1, 24), with the opening (2) being formed. The length of the wall piece (7, 23) is dimensioned relative to the width of the hollow section (1, 24) in such a way that the wall piece (7, 23), with its free end (10, 26), at least comes into contact with the opposite hollow section wall (11, 27), and the free end (10, 26) is then joined to the hollow section wall (11, 27).

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： 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： The invention relates to a method for producing a peripherally closed hollow profiled element by means of internal high-pressure forming, a hollow elongated blank (5) being inserted into an internal high-pressure forming tool (1), and the blank (5) located completely inside the forming tool (1) after the insertion being compressed in a region lying between its ends (9, 10) during the closing operation of the forming tool (1), after which the compressed blank (5) is expanded into the final shape of the hollow profiled element by means of fluidic internal high pressure. In order to permit reliable production of the hollow profiled element even during pronounced compression deformations of the blank (5) of the hollow profiled element, which are produced during the closing of the forming tool (1), it is proposed that the ends (9, 10) of the blank (5) be trimmed before the compression operation, with a respective beveled front face (12, 13) being formed, and that the trimming contour of the ends (9, 10) and the beveling angle (α) be selected in such a way that the ends (9, 10) are deformed by means of the compression operation in such a way that their front faces (12, 13) have an essentially plane form and assume a position which is as perpendicular as possible to the longitudinal extent of the blank (5).

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： A punch designed for producing holes in the walls of hollow parts, the part being subjected to the action of high pressure in the interior by a medium during the punching. In particular when producing hollow parts by the internal high pressure forming process, it is normal practice, following the forming and with the part still located in the forming tool, to make holes in the wall. In order to avoid a drop in the internal high pressure when cutting through the wall of the part, the punch is designed so as to taper at an angle toward the cutting edge in its region plunging into the part to be punched. As a result, sealing of the hole occurs during the punching.
