    • 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.
    • 提供了一种基于塑料加工技术的制造方法,其可以在制造结合在VGS涡轮增压器中的可调节叶片时尽可能地消除切割和焊接。 本发明的特征在于:将坯料从具有基本上恒定厚度的金属材料冲压成成形材料(W),作为可调叶片(1)的起始形式; 此后,成形材料(W)被压缩在一对相对的模具之间以形成具有期望形状的叶片部分(11),轴部分(12)等; 之后修剪从产品部分突出的非产品部分; 然后通过将成形材料(W)的轴部分(12)压靠在一对模具上而使轴部分(12)具有期望的直径厚度,并且其形状和尺寸接近于 针对可调叶片; 并且在完成对应于可调叶片(1)的叶片宽度的叶片高度时,具有近净形状的成形材料(W)被一对相对的模具挤压,使得叶片高度的精度在完成 状态可以实现。
