DISPOSITIVO PER TAGLIARE ANELLI DA UN CORPO CILINDRICO CAVO APARETI SOTTILI E ALLUNGATO

摘要

A device for cutting rings from a hollow, cylindrical object, comprising an annular die in which a rotatable cutting head is arranged. The cutting head supports one or more cutting rollers which are journalled with axial play in a radially movable slide. The cutting edges of the cutting rollers cooperate with the die and are forced away from the die by spring means. A guide body is provided which can bear on the side of the die and which supports a guide along which the cutting rollers or parts connected thereto can roll down. This guide is positioned such that the desired cutting clearance remains between the cutting edge of the cutting rollers and the die.
