PRESS-MOLD FOR MOLDING BLANKS OF ABRASIVE WHEELS Russian patent published in 2003 - IPC

Abstract RU 2216440 C2

FIELD: abrasive working, possibly manufacture of abrasive wheels with different inner diameter without changing holder and die. SUBSTANCE: press mold includes die with inner annular surface, core, upper and lower molding plates and clamp. The last is in the form of ring having built-in sectors jointly secured by their one ends to ring. In order to tune press for other dimensions and type of wheels with the same outer size, sector blanks are rotated on axles by means of mechanism for their synchronous rotation and forming respective diameter of opening. EFFECT: lowered labor consumption for molding abrasive wheels. 4 dwg
