Abstract (en)
[origin: US4831855A] A flaring tool and flaring apparatus for cylindrically flaring the ends of tubes. The flaring tool is provided in the vicinity of one end thereof with flaring elements that are fixedly connected thereto and have an at least approximately spherical shape. The flaring elements are essentially in point-type contact with the tube and generate high specific deformation forces during flaring. When the flaring tool is rotated about its axis, the tube end is continuously flared. The flaring apparatus has an adapter that can be shifted via a thread connection. The adapter fixedly accommodates the flaring tool, and can be connected to a drive unit.
