Abstract
A method for manufacturing a shoe of a swash plate-type refrigerant compressor for vehicle is disclosed. The method comprises a first step, in which a spherical protrusion is made on a first side surface of a plate material by a press operation. The method comprises a second step, in which the spherical protrusion is punched from the plate material to form a shoe intermediate shape. The method further comprises a third step, in which the shoe intermediate shape is forged to form a final shoe shape. The two press operation steps for forming the shoe intermediate shape and punching it from the plate material may be performed by continuously feeding the plate material into a press machine. Thus, shoes having improved dimensional accuracy may be obtained because the necessary amount to be deformed during the forging step is reduced.
