Abstract
Abstract A rotor machine designed to cup-off bellows' throats comprises a device for cutting-off the bellows' throats in the form of a rotor. Said device comprises a shaft, slides arranged parallel to the shaft axis and provided with mandrels for receiving the bellows, and tool units, each tool unit comprising a cutting tool in the form of a pair of cutters. One of said cutters, cylindrical in shape, is installed in the hollow holder coaxially with its inner surface which is eccentric relative to its outer surface. The other one of said cutters is made in the form of a ring consisting of two half-rings, the longitudinal axis of said ring being coaxial with the axis of the inner surface of the hollow holder at the moment of receiving the bellows to be cut-off. The half-rings are adapted for closing radially when clamping the bellows and for opening when releasing the bellows after its throat has been cut-off. The rotor machine according to the invention ensures high-quality cutting-off of bellows' throats and a more efficient use of labor.

Claim 1
Independent Claim
473 words
A rotor machine for cutting-off hollow articles comprising: a bed; a device for loading parts installed on said bed; a device for cutting-off parts mounted on said bed and being kinematically linked with said device for loading parts, said device for cutting-off parts made in the form of a rotor comprising a shaft installed in said bed and tool units mounted on said shaft, each of said tool units consisting of a hollow holder arranged parallel to the axis of said shaft and having an inner surface which is eccentric relative to its outer surface and means for reversably turning said hollow holder relative to the axis of the outer surface and a cutting tool in the form of a pair of cutters arranged parallel to the axis of said shaft and having means to coaxially align the cutters with each other at the moment in time when the part is introduced in the device for cutting-off parts, one cutter of said pair of cutters being cylindrical in shape with a cutting edge on one of its faces, said cutting edge lying in the same plane as a face of the hollow holder, said cutter being installed in said hollow holder coaxially with its inner surface with a provision for moving said cutter towards the part in a direction parallel to the axis of said shaft by means of a carriage upon which the hollow holder is located, an axle installed upon said carriage, a roller carried on said axle and a master form, connected to said bed, which interacts with said rollers, the other one of said pair of cutters is in the form of a ring and is provided with a cutting edge on the face directed to the face of the first cutter of said pair of cutters, said other one of said pair of cutters having means to provide that its longitudinal axis is coaxial with the axis of the inner surface of the hollow holder at the moment in time when the part is introduced into the device for cutting-off parts, said other one of said pair of cutters being formed by two half-rings and constructed to close radially relative to their axis when clamping the part and for opening when releasing the cut-off part; a means for closing and opening said half-rings radially relative to their axis; a drum installed on said rotor shaft at one side of said tool units; slides mounted in said drum parallel to the axis of said shaft to move the part in a direction parallel to the axis of said shaft; mandrels mounted on each of said slides for receiving the part; a means for reversable turning of each of said hollow holders relative to the axis of its outer surface, said means being mounted in each of said tool units.
Claim 2
Dependent Claim
473 words
A rotor machine for cutting-off hollow articles comprising: a bed; a device for loading parts installed on said bed; a device for cutting-off parts mounted on said bed and being kinematically linked with said device for loading parts, said device for cutting-off parts made in the form of a rotor comprising a shaft installed in said bed and tool units mounted on said shaft, each of said tool units consisting of a hollow holder arranged parallel to the axis of said shaft and having an inner surface which is eccentric relative to its outer surface and means for reversably turning said hollow holder relative to the axis of the outer surface and a cutting tool in the form of a pair of cutters arranged parallel to the axis of said shaft and having means to coaxially align the cutters with each other at the moment in time when the part is introduced in the device for cutting-off parts, one cutter of said pair of cutters being cylindrical in shape with a cutting edge on one of its faces, said cutting edge lying in the same plane as a face of the hollow holder, said cutter being installed in said hollow holder coaxially with its inner surface with a provision for moving said cutter towards the part in a direction parallel to the axis of said shaft by means of a carriage upon which the hollow holder is located, an axle installed upon said carriage, a roller carried on said axle and a master form, connected to said bed, which interacts with said rollers, the other one of said pair of cutters is in the form of a ring and is provided with a cutting edge on the face directed to the face of the first cutter of said pair of cutters, said other one of said pair of cutters having means to provide that its longitudinal axis is coaxial with the axis of the inner surface of the hollow holder at the moment in time when the part is introduced into the device for cutting-off parts, said other one of said pair of cutters being formed by two half-rings and constructed to close radially relative to their axis when clamping the part and for opening when releasing the cut-off part; a means for closing and opening said half-rings radially relative to their axis; a drum installed on said rotor shaft at one side of said tool units; slides mounted in said drum parallel to the axis of said shaft to move the part in a direction parallel to the axis of said shaft; mandrels mounted on each of said slides for receiving the part; a means for reversable turning of each of said hollow holders relative to the axis of its outer surface, said means being mounted in each of said tool units.
