Abstract: 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.

Abstract: 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.

Abstract: 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).

The tool (1) is designed both for forming the hollow section (2) and for making an embossment on the outside of the hollow section (2) and for making a hole in the hollow section (2). For this purpose, the tool (1) has an embossing punch (11) displaceable transversely to the longitudinal extent of the hollow section (2) and also a perforating punch (13) arranged coaxially in the embossing punch (11).

Abstract: An internal high pressure forming installation is provided, in which a forming tool with upper and lower dies form a forming chamber for pressure forming a closed hollow profile. The installation has at least one axial punch which can seal the hollow profile be sealed at one end and apply an internal high pressure to expand the hollow profile. The installation includes a rapid filling device which can pre-fill the hollow profile with pressurized fluid when the axial punch is drawn back from the hollow profile end. In order for the production of hollow profiles to be suitable for mass production in a simple manner, the filling attachment is transported on the axial punch which brings the filling attachment into a contact position on the forming tool in order to fill it and, after the filling, guides it into a position remote from the forming tool.

Abstract: A tool for cutting a hollow profile is designed both for cutting a flange on the hollow profile and for forming the hollow profile using an internal high pressure forming process. The tool has at least one cutting device which extends parallel to the longitudinal extent of the hollow profile, has a cutting edge and is displaceable transversely to the hollow profile. A side of the cutting device that faces the hollow profile is designed as a shaping die wall, against which the hollow profile bears at least during the internal high pressure forming. In addition, the tool my have an integrated embossing punch and also a perorating punch formed coaxially thereto, thereby also enabling optional embossing and/or perforating of the hollow profile in addition to the cutting and the internal high pressure forming.

Abstract: A process and apparatus for manufacturing slot-shaped openings on hollow sections is disclosed in which the openings are produced by a piercing cutting operation by means of a blade-type cutting tool by the displacement of material in a cutout-free manner. During the slotting operation, the hollow sections are supported from the inside around the openings to be formed. In order to produce slot-shaped openings in a simple manner while maintaining the shape of the hollow section on arbitrarily constructed hollow sections in a reliable process free of positional tolerances, the hollow section is inserted in a recess of an internal high pressure forming tool. The hollow section is slotted by the interaction of the cutting action of a cutting tool integrated in the internal high pressure forming tool and an internal high pressure generated inside the hollow section.

Abstract: The electric food processor has a housing in which there is disposed an electric motor with a motor shaft. The motor shaft, via a gear mechanism, drives three or more concentric output drives at different rotational speeds. The common axis of rotation of the output drives is spaced a distance from the motor shaft. Working tools are selectively coupled to the output drives and the working tools rotate in a working container which is placed on the housing. In order to expand the possible uses of the food processor, the fastest output drive rotates at a speed that is suitable for a mixing tool, and the gear mechanism has at least two sets of input gear teeth that are rotatably mounted independently of each other, so that the fastest output drive can be driven out of direct engagement with the slower output drives.

Abstract: The invention relates to a process and apparatus for manufacturing hollow sections with cross-sectional expansions in end portions thereof. A hollow blank is widened and calibrated by internal high pressure forming by means of a forming tool receiving it, and, after the calibration, is separated in the area of the widening while forming two hollow sections with cross-sectionally widened ends facing one another in the separated position. In order manufacture from a hollow blank hollow sections with the lowest possible reject rate and therefore in a reliable process, which are cross-sectionally widened on the end side by means of high degree for forming, the blank is widened while the forming tool is open and is simultaneously upset to form a rotationally symmetrical bulging hollow section by means of a pressure force which is axially directed from the outside to at least one of the two blank ends.

Abstract: An electric food processor has a housing in which there is arranged an electric motor with a motor shaft. A belt drives a step-down belt pulley of a vertical first shaft from the motor shaft. The first shaft is disposed vertically in the housing and working tools running in a working container that can be placed on the housing of the food processor can be coupled to the first shaft. A compact and flat construction of the food processor is assured in that the electric motor is aligned horizontally in the housing. The motor shaft rotates about a substantially horizontal axis. An intermediate shaft is mounted essentially vertically in the housing. The intermediate shaft is coupled to the motor shaft with a half-crossed, first belt and, on the other hand, is coupled to the vertical first shaft by an open, second belt. The first shaft is thus driven by the motor through the intermediary of the intermediate shaft.

Abstract: An exhaust manifold for an internal combustion engine includes an inner duct with flanges for connection to an engine. The inner duct is enclosed by an envelope consisting of two shells which are interconnected at their edges by seams. Between the inlet flanges, the seams are disposed at a substantially greater distance from the inner duct than in other areas such that, in a cross-sectional plane disposed between, and extending normal to, the flanges, the envelope has drop-like shape.
