METHOD FOR MAKING PARTS SUCH AS CYLINDERS BY SPINNING AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2003 - IPC

FIELD: automobile manufacture, namely production of cylindrical parts by spinning. SUBSTANCE: method comprises stage by stage working of blank in spinning machine tool with possibility of simultaneously working several blanks without readjustment of modes of machine tool operation and working tool. Multispindle lathe includes unit of spindle heads mounted uniformly along circle with possibility of rotation around their own axes and around their common axis; lengthwise rest mounted with possibility of reverse motion along its guide. Mandrels are mounted in spindle heads. Expanding heads for spinning are rigidly mounted on lengthwise rest coaxially relative to spindle heads; mechanism for simultaneously drawing apart all deforming members is mounted in guide of lengthwise rest. Spinning heads and above mentioned mechanism are mutually joined through gear transmission. EFFECT: possibility for making ready products at using one machine tool, single adjustment of modes of machine tool and tools for all stages of simultaneous working of several blanks without changing base of blank. 3 cl, 3 dwg
