Abstract
A method for manufacturing a piston for internal combustion engines, compressors and the like, comprising a head portion articulately connected to a separate skirt portion, wherein the skirt portion comprises a steel tubular part obtained by cutting, bending and closing of a piece of steel strip, the outer surface of said tubular part being covered by a layer of antifriction material bonded to said outer surface prior to the cutting, bending and closing of the steel strip.
Claims8
A method for manufacturing a piston for internal combustion engines, compressors, and the like, the piston including a head portion and a separate skirt portion, comprising the steps of:
- providing a strip of steel;
- bonding a layer of antifriction material to one of the surfaces of the steel strip;
- cutting, forming and locking the steel strip into a substantially cylindrical shape subsequent to said bonding step to form the skirt portion with said antifriction material on the outer surface of said skirt portion, forming a pair of articulation holes in said skirt portion, the walls of which include said antifriction material;
- and
- articulating the head portion to the skirt portion such that the same do not contact each other during operation.
