摘要： A support may include a hollow metallic tube extending over an axis and may include two opposing ends. The tube may include a plurality of sections disposed along the axis. A first section may be disposed at an end of the tube and include a first inner diameter, a first outer diameter, and a first wall thickness. A second section may be separated from the first section via a first transition zone. The second section may include a second inner diameter, a second outer diameter, and a second wall thickness. A third section may be disposed remote from the first section and be separated from the second section via a second transition zone. The third section may have a third inner diameter, a third outer diameter, and a third wall thickness. The wall thickness, inner diameter and outer diameter may vary along the tube between the plurality of sections.

摘要： A method and apparatus manufactures a closed structure part without flange having a curvature and welded edges along a longitudinal direction of the part and further having a varying cross-sectional shape, from two metal plates. Each of two metal plates provided with a curvature along the longitudinal direction of the plate and provided with both ends in a width direction of the plate, are press-formed such that a folding line is formed at positions corresponding to a non-welded bent edge in a cross section of the part, and stacked on each other vertically such that their bulging sides face outward. Their left ends and right ends in the width direction are mutually welded along the longitudinal direction to form welded edges.

摘要： A method of manufacturing a pipe with different diameters along a longitudinal direction that has a small diameter portion, a large diameter portion, and a diameter-changing portion provided between the small diameter portion and the large diameter portion and is formed by press forming a blank made of a metal sheet includes press forming the blank with a U-shape forming die into a U-shaped formed part and press forming the U-shaped formed part with an O-shape forming die set into a circular cross-section formed part. A length of a vertical wall of the U-shape forming die is longer than a length of a vertical wall portion of the U-shaped formed part. In the O-shape forming die set, a die mating line is inclined downwardly, and a ratio t/D of a sheet thickness t of the blank to a diameter D, which represents a diameter of a portion of the O-shape forming die set corresponding to the small diameter portion and a diameter of a portion of the O-shape forming die set corresponding to the large diameter portion, is 0.010≦t/D≦0.080.

摘要： A fitting for thick-walled pipes, having a contact region and a pressing region, the pressing region being arranged on the side of the contact region facing towards the pipe insertion opening, and the wall thickness in the pressing region being at least in sections less than the wall thickness in the contact region. The invention also relates to a method for producing a fitting for thick-walled pipes, in which a thick-walled pipe is radially widened in a fitting region arranged at one pipe end so that the internal diameter of the fitting region corresponds substantially to the external diameter of the pipe and the wall thickness in the fitting region corresponds substantially to the wall thickness of the rest of the pipe.

摘要： A method for draw forming a desired contour to the outer diameter of a tubular work piece provides that the selected work piece have a wall thickness uniform throughout its length. The outer diameter of selected work piece is reduced along essentially only a part of the starting metal blank by drawing the metal blank only partly through a die or only partly through each one of a succession of dies. The resulting drawn reduced diameter will have essentially the same wall thickness as the starting blank. If a thinner wall thickness is desired on the reduced outside diameter, an internal mandrel can be inserted in the starting tube, which will work with the draw die to decrease the resulting wall thickness of the drawn tube to an amount less than the starting tube. The workpiece recovered after the drawing method is useful for producing an automotive fuel tank filler tube or an automotive instrument panel support beam.

摘要： A method for forming a hollow part (18) that allows the use of hydroforming in cases where the part interconnects between sections having extreme variations in cross-section. A complete hollow part (18) is formed by joining a hydroformed hollow section with hollow sections. A method for securing a fastener sleeve (102) insert in a pre-fabricated hollow part (100) is also provided. In this method, the hollow part (100) is deformed slightly to form flanges (108) that secure the insert (102) in the part. Once the insert (102) is secure in the hollow part, fasteners can be applied to the part without collapsing it.
摘要翻译：一种用于形成中空部分（18）的方法，该方法允许在横截面极度变化的部分互相连接的情况下使用液压成型。通过将液压成型的中空部分与中空部分接合而形成完整的中空部分（18）。还提供了一种用于将紧固件套（102）插入件固定在预制中空部件（100）中的方法。在该方法中，中空部件（100）略微变形，以形成将插入件（102）固定在部件中的凸缘（108）。一旦插入件（102）固定在中空部件中，紧固件就可以施加到零件上而不使其折叠。
