METHOD FOR MANUFACTURING ABRASIVE WHEELS AND DEVICE FOR ITS EMBODIMENT Russian patent published in 2000 - IPC

Abstract RU 2149096 C1

FIELD: abrasive industry. SUBSTANCE: vulcanized abrasive mixture is rolled into plates from which circular blanks are cut out. Blanks are assembled in stack on rod, tightened and placed in press mold for final molding of stack. When molding, force increasing monotonically from center to periphery is applied to stack. Press mold represents body consisting of bushing with holder. Body accommodates composite mandrel made as a rod with attachment. Upper and lower molding plates are positioned on mandrel. Holder and rod are made of steel and provided with through recesses located over perimeter of internal surface of holder and external surface of rod. Bushing and attachment are manufactured of porous antifriction material. Upper and lower flexible members in the form of truncated cones facing each other with their smaller bases are arranged between molding plates. Lower flexible member is positioned on lower molding plate. Upper molding plate is arranged on upper flexible member. EFFECT: higher mechanical strength of wheels. 2 cl, 3 dwg
