Title:
METHOD OF MANUFACTURING FRICTION-PROOF RING WITH COOLING CAVITY
Document Type and Number:
Japanese Patent JP2005042626
Kind Code:
A
Abstract:

To provide a method for manufacturing a friction-proof ring with a cooling cavity having a high cooling capacity at a low facility cost and few manufacturing processes.

The method for manufacturing the friction-proof ring with the cooling cavity includes setting of an annular metal tube 8 having substantially the same outer diameter as an inner diameter of an annular friction-proof ring 3 at an inner peripheral side of the annular friction-proof ring 3, bringing a circumferential surface of a taper shape punch 9 of circular cross section into contact with an inner peripheral side of the metal tube 8, loading a load to a punch 10, relatively moving the punch 10 in an axial direction of a piston to the friction-proof ring 3, and press bonding the friction-proof ring 3 to the metal tube 8.
