摘要： A manufacturing method based on a plastic working technique which can eliminate cutting and welding as much as possible in manufacturing an adjustable blade incorporated in a VGS turbocharger is provided. The present invention is characterized in that: a blank is punched out from a metal material having a substantially constant thickness to be a shaped material (W) as a starting form for an adjustable blade (1); thereafter, the shaped material (W) is compressed between a pair of opposed dies to form a blade portion (11), a shaft portion (12) and the like having desired shapes; thereafter a non-product portion protruding from a product portion is trimmed; then the shaft portion (12) is rolled by pressing the shaft portion (12) of the shaped material (W) against a pair of dies to have a desired diametrical thickness and a near net shape having a shape and dimensions thereof made close to the aimed at adjustable blade; and in finishing the vane height corresponding to a blade width of the adjustable blade (1), the shaped material (W) having the near net shape is pressed by a pair of opposed dies, so that an accuracy of a vane height in a completed state can be achieved.

摘要： The invention relates to a process for hard-rolling a component (2) to be loaded along a load axis (1) in a notch (3) running approximately parallel to the load axis (1) and having a minimum radius of curvature (4) to be determined in a cross-section parallel to the load axis (1). The notch (3) is hard-rolled over a plurality of adjacent paths (5) along the load axis and approximately perpendicular to the load axis (1), each path (5) covers only a part of the notch (3). This generates residual compressive stresses having axial (17) and tangential components (18) in relation to the load axis, with the axial components (17) substantially greater than the tangential components (18). This process is particularly suitable for hard-rolling a retaining groove (3) in the base (11) of a turbine blade (2).

摘要： An embodiment of a tool assembly (31) includes a hub (22) connected to a distal end of a spring-loaded shaft assembly disposed along a first axis (24). An upper hub portion (36A) is adjacent to the distal end of the spring-loaded shaft assembly aligned with the first axis (24), and a lower hub portion (36B) extends along a second axis (34), forming a nonzero angle relative to the first axis (24). A roller disk (20) is joined to the lower portion (36B) of the hub (22), and is rotatable about the second axis (34) parallel to the second portion (36B) of the hub (22). A load cell (60) is disposed along the first axis (24) between a proximal end of the shaft and the roller disk, and is adapted to measure a downward force applied along the shaft assembly.

摘要： To make vane airfoils for an axial flow compressor metal strip (34) is first contour rolled to a cross section comprised of two oppposing airfoils (38, 40) separated by a center rib (42), where one (36) of the faces of the strip (34) is kept planar. The rib (42) is used to guide the strip (34) into dies where it is notched and slotted (at 66a, b, c) to define individual airfoils. Next, die stamping makes concave the planar surface (36) of each airfoil.

摘要： A method of forming an airfoil includes placing (102) a material onto a die (10) that is heated (100) to a predetermined temperature to pre-heat (106) the material to a first temperature, while the die is in an open position (104). The method further includes closing (108) the die at a predetermined rate and holding (110) the die in a closed position for a predetermined period of time at a first force. The method still further includes removing (114) the part from the die, cooling (116) the die, placing (124) the part onto the die, and closing (126) the die at a second force.

摘要： A novel manufacturing method is provided which can actually achieve mass production of an adjustable blade and a VGS turbocharger having the adjustable blades incorporating therein, wherein a shaft portion is processed to have an aimed at diametrical thickness by rolling in place of cutting so that a cutting operation requiring much time may be eliminated as much as possible from a manufacturing process of the adjustable blade, and wherein a shaft elongation and a sharp edge caused by the rolling can be extremely inhibited to thereby eliminate an additional cutting operation conventionally performed for correcting the shaft elongation and the sharp edge. The present invention is characterized in that a metal shaped material as a starting form for an adjustable blade (1) integrally provided with a blade portion (11) and a shaft portion (12) is formed to have a near net shape having a shape and a size made close to those of the aimed at adjustable blade (1), and in forming the shaft portion (12), a shaft portion forming section of the shaped material is rolled to have a desired diametrical thickness.
