| A process for producing an aluminum alloy-made forged scroll part includes a step of casting an aluminum alloy material into a round bar having a diameter of 130 mm or less, the aluminum alloy material comprising 8.0-12.5 mass % of Si, 1.0-5.0 mass % of Cu and 0.2-1.3 mass % of Mg; a step of cutting the aluminum alloy round bar into a stock material for forging; a step of subjecting the stock material to upsetting at an upsetting ratio of 20-70% to form a pre-shaped product that is a workpiece; and a forging step of applying pressure onto the workpiece with a punch at a temperature of 300-450null C. to form a scroll wrap in a direction of the punch pressure, and wherein the forging step includes a single step in which a forged scroll part is press-formed while a back pressure smaller than the punch pressure is applied to an end of the scroll wrap in a direction opposite to the punch pressure direction. With this method, it is possible to produce a forged scroll part capable of suppressing occurrence of coarse primary Si crystals and reducing a variation in height of a wrap in a scroll part and in every scroll part being forged. | ||||||

| 125 | Methods for making scroll compressor element | US515683 | 1995-08-16 | US5615480A | 1997-04-01 | John P. Waggoner |
| A high pressure forming process is used to form asymmetric scroll compressor elements wherein a single or multiple piece die is closed at one end by a stop which is formed to correspond to a side of the scroll compressor element opposite to a scroll. A punch sized to fit within the die includes an endface having a scroll shaped cavity. A blank of an appropriate metal is placed in the die against the stop and the punch is then inserted into the die and fully extended to form the blank into a scroll compressor element with a single stroke of the punch. The punch includes vent holes for allowing trapped gases and lubricants to escape as the scroll is formed. The punch may also include an ejector system to facilitate removal of the scroll compressor elements from the punch/die combination. The stop may be defined by a second punch which can be moved into the die for forming parts or can be held stationary during part formation and then moved to facilitate removal of scroll compressor elements from the punch/die combination. It may be desired in some applications to heat the die, punch, stop/punch and blanks. | ||||||

| 128 | Swash plate type compressor shoe | US699109 | 1985-02-07 | US4662267A | 1987-05-05 | Yoshihiro Kaku; Keiichiro Otsu |
| There are disclosed a shoe which is interposed between a swash plate and a piston of a swash plate type compressor and which converts rotary movement of the swash plate into reciprocal movement of the piston, and a method for manufacturing the same. The shoe has a hemispherical part which is in slidable contact with the surface of a piston defining a hemispherical recess, and a flat end face which is in slidable contact with a bottom end face of the swash plate. According to the method of the invention, a columnar element is compressed in the axial direction for plastic deformation in such a manner that one end of the columnar element is deformed along the inner surface of a hemispherical recess of a die while the other end is urged against the flat end surface of another die. A shoe can be easily manufactured with this method, which has a flank between the hemispherical part which is in slidable contact with the surface of the piston defining the hemispherical recess and the bottom end face of the swash plate which is in slidable contact with the swash plate. According to this method, a hole of a predetermined size may alternatively be formed at the end face of a columnar part of the element, and the end face of the columnar part is cut into a conical shape while reducing the diameter of the hole toward the opening side thereof. Still alternatively, the periphery of the end face of the columnar part may be cut into a conical shape and then pressed to form a hemispherical part. A great flow of the material and local exertion of a high load on the element are prevented. | ||||||

[Problem to be Solved] An object of the present invention is to provide a novel method of manufacturing a lever plate that is made of a material having a relatively small thickness but nonetheless has an engaging protrusion having an adequate thickness and an adequate height. A lever plate in a VGS type turbocharger according to the present invention is a lever plate that is incorporated in an exhaust guide assembly in a VGS type turbocharger. The lever plate has a fitting hole into which a shaft part of the adjustable vane is fitted formed at a position close to one end of an elongated plate main body thereof and an engaging protrusion to be engaged with the drive ring formed at the other end thereof. The engaging protrusion is formed by bending a blanking material having the shape of an elongated flat plate. The engaging protrusion is pressed in a direction of raising thereof so as to have a thickness greater than the thickness of the plate main body of the lever plate, and opposite side peripheries of the engaging protrusion are subjected to finish blanking to have an arc shape. |
