Abstract
PURPOSE: To manufacture a pinston ring having excellent air-tightness with a cylinder liner by producing pressed powder by using a true circular form of a mold in the manufacturing process with a sizing process for a sintered alloy piston ring.
CONSTITUTION: An atomized iron powder is mixed with a lubricant and then molded by compression in a real circle form of a mold to manufacture a piston ring element material whose dimension (outside diameter D1) is D+(A-C)/π, where D is the nominal diameter of piston ring, C is the matching mouth aperture of piston ring, and A is the width dimension of matching mouth cut in the subsequent process). The element material is sintered and cut off to the width A to provide a matching mouth. Then, the material is put in a real cycle form of a sizing die for sizing so that the matching mouth size is 0W0.2mm, the upper and lower sides are pressed to close the matching mouth, and the peripheral surface closely contacts with the inside circumference of the die. Lastly, a jig having the same outside shape and dimension as the inside circumferential shape and dimension of the piston ring in a free state is fitted into it and a heat treatment is applied. Then, the jig is removed.
