SU1660869A1 - Rotor cut-off tool unit - Google Patents

Abstract

The invention relates to the processing of metals by pressure and can be used in mechanical engineering for cutting edges of hollow parts on rotary lines. The purpose of the invention is to increase productivity and reliability. The rotor tool block for cutting parts comprises a housing, a holder with a split matrix 6 and a mechanism for its connector in the form of a pusher 10, a wedge 11 and an emphasis made, for example, in the form of a double-arm lever 15, and a feeder for parts 27 with a mandrel 29. The part to be cut is fed by the mandrel 29 inside the die 6 and its edge is cut off when the die is jointly rotated and radially moved by means of a connector mechanism. 2 hp ff, 7 ill.

Claims (3)

Claim 1. The rotor tool block for cutting parts, comprising a housing in the bearing bearings of which a hollow cage with a drive gear is mounted rotatably, a detachable matrix with a cutting edge, mounted to interact through its connector mechanism with a stationary copier, and a parts feeder installed with the ability to interact with another stationary copier, characterized in that, in order to increase productivity and reliability, the clip is equipped with guides mounted parallel to the axis e rotation, the detachable matrix is made with a wedge outer surface and mounted on these rails with the possibility of longitudinal movement along them, while the matrix connector mechanism is made in the form of a pusher mounted in a cage with the possibility of axial movement and joint rotation with it, a wedge rigidly connected to a pusher and installed with the possibility of interaction of its wedge surface with the outer wedge surface of one of the parts of the split matrix, and the stop with a transverse protrusion and wedge the surface facing the indicated part of the detachable matrix, and with the cylindrical surface facing the inner surface of the cage installed in the cage with the possibility of movement relative to the pusher and interact with it through the said transverse protrusion and with the outer wedge surface of the second part of the detachable matrix, while the stop is spring-loaded in the direction of the matrix interacting with it. 2. The block according to claim 1, characterized in that the emphasis is made in the form of a two-shouldered lever with a transverse protrusion pivotally mounted inside the hollow cage and spring-loaded with one shoulder relative to the pusher, the other shoulder of the two-shouldered lever from the side of the split matrix wedge surface, and from the side of the cage with a cylindrical surface, the angle between the specified wedge surface and the Central generatrix of the cylindrical surface is equal to the angle on the clone of the wedge outer surface of the split matrix to its longitudinal axis and the transverse protrusion of the two shoulders of the lever is installed with the possibility of interaction with the end of the pusher. 3. Blockpop1, characterized in that the emphasis is made in the form of a crawler mounted in a cage with the possibility of limited reciprocating movement in the direction of the axis of rotation of the cage and spring-loaded relative to its bottom. 1660869 - Fiz. 6 3ff Fig!
