摘要： The invention relates to a flange arrangement (2, 14, 25) of an engine cylinder head (22) and to a process for producing it. To simplify them as much as possible without losing the functionality of the flange arrangement (2, 14, 25), it is proposed that the flange arrangement (2, 14, 25) have at least two single-piece individual flanges (1a-d, 13a-c, 26), which bear against one another with in each case at least one peripheral region (8a-d, 15, 20, 28, 29) overlapping, in such a manner that in the overlapping area their securing bores (3, 16, 27) for attaching them to the cylinder head (22) are aligned.

摘要： A method for manufacturing an air-gap-insulated exhaust pipe having a branch stub, as well as an exhaust pipe produced according to such a method and a tool for forming such an exhaust pipe. Two tubes are inserted into one another to form a double tube. The double tube is placed in a first internal high-pressure shaping tool, and exposed to internal high pressure fluid such that it expands to match the contours of the engraving of the first shaping tool, and a double-walled branch stub is blown out of the double tube. The partially formed double tube is then placed in a second internal high-pressure shaping tool, with the double tube being surrounded, between the two ends including the branch stub, circumferentially and throughout by a corresponding design of the engraving, by an expansion chamber. The outer tube is expanded between the outer tube and inner tube under high pressure up to a precise fit with the engraving of the second shaping tool to form an insulating air gap, with the end of the branch stub being supported externally without yielding via a second counterpunch. The finished double tube is removed from the second shaping tool and a cap area of the branch stub, containing the end, is cut off to form a through opening between the interior of the inner tube and the ambient environment outside the air-gap-insulated exhaust pipe.

摘要： A process for manufacturing an air-gap-insulated exhaust elbow of a motor vehicle exhaust system achieves in a simple manner a manufacturing of space-saving air-gap-insulating exhaust elbows which is reliable with respect to the process and can be precisely reproduced. The exhaust elbow is joined together from several air-gap-insulated exhaust pipes as well as the pertaining entry flanges and the exit flange, which, by way of an internal high-pressure metal forming process, are shaped in an air-gap-insulating manner from one double pipe respectively. The ends of the air-gap-insulated exhaust pipes which are to be connected with one another are first trimmed while opening the respective air insulating gap and are then fitted into one another. In such case, the ends are shaped such that the fitted connections of the outer pipes and of the inner pipes of the exhaust pipes to be connected are made with play. The mutually connected outer pipe ends of the exhaust pipes are welded together at the point of their fitted connection while forming a circular bead. The connection-free ends of the exhaust pipes to be connected to the cylinder head are fitted together with the respective pertaining entry flanges and are welded together and the connection-free end, which faces away from the cylinder head, of the last one of the branched exhaust pipes arranged in a row side-by-side, is fitted together with the exit flange and is welded to the latter.

摘要： A process and a device produces an assembly linkage on a hollow profile which is shaped for the installation of the assembly part by internal high-pressure remodeling. In order to achieve the shaping of an assembly linkage in a component space-saving, for a subsequent assembly correctly positioned, and with regard to its contour exactly fitted to the assembly part, in simple manner and even with high degrees of remodeling in a secure process, the hollow profile, under internal pressure, which is smaller than the remodeling pressure, is indented at the place of the to-be-produced assembly linkage by a die and by forming a rough contour. Afterward, while the die remains in this indenting position, a fluid high pressure is created in the hollow profile. Thereby, the hollow profile sides surrounding the die are molded to the external contour of the die, and that after releasing the fluid high pressure and the subsequent removal of the die, the finished trough-shaped assembly linkage is released.

摘要： A method for manufacturing an air-gap-insulated exhaust manifold, including exhaust-conducting inner tube sections and an outer shell divided into an upper shell and a lower shell, with the inner tube sections, of which at least one is designed as a curved tube, being plugged into one another. The inner tube sections plugged into one another are inserted as an assembled component into the lower shell, centered relative to the outer shell that is formed later, with the upper shell then being placed on the lower shell and pressed against the latter. Then the upper and lower shells and the inner tube sections are welded to the outer shell at those points at which they pass through the outer shell. In order in simple fashion always to ensure a sliding fit on the inner tube sections as well as the formation of a uniform air gap insulation of the inner tube sections following completion of the manufacture of the exhaust manifold, it is proposed to connect the inner tube sections with each other forcewise before they are inserted into the lower shell by means of a connecting element in each case made of a heat-volatile material, with the connecting elements being dissolved under the influence of heat following the welding of the upper and lower shells with the inner tube sections.

摘要： 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.

摘要： A device for producing a hollow body according to an internal high pressure metal forming process has a tool which is divided along a mold joint into a stationary tool part and a liftable tool part. The tool has an impression for receiving a tube-shaped blank. A press opens and closes the tool. An axially movable slide is attached to an open end of the blank, through which a pressure medium is introduced into the blank. A hydraulic working cylinder which is angularly and vertically adjustable on a support member has a piston rod which holds the slide and which displaces the slide axially. A pair of pull rods connect the tool and the working cylinder and are arranged on opposite sides of the piston rod at the same level as the piston rod, each pull rod extending into the end-side portion of the mold joint and being releasably anchored to each of the stationary tool part and the liftable tool part in a form-locking manner in corresponding recesses along the mold joint. The recesses are configured such that after a working cycle the liftable tool part can be lifted away from the pull rod in a vertical direction without resistance. In another embodiment the pull rods are releasably anchored to a holding wall in a form-locking manner in corresponding recesses, the holding wall being stationarily fastened to the stationary tool part.

摘要： A method and an apparatus are provided for internal high-pressure forming of a workpiece in a closed internal high-pressure forming die. The workpiece is expanded owing to the internal high fluid pressure exerted by a pressure generator and coming to rest on the cavity of the forming die. The workpiece and the forming die form friction partners in the areas of contact. In order to improve process reliability during the internal high-pressure forming of workpieces and to expand the scope of the method, vibration is imparted directly to at least one of the friction partners by a vibration generator during forming.
