Patent ID: 11072018

Abstract:
A flaring tool for flaring an end of a tube includes a locking mechanism having a collar and a collet with two or more collet pieces. As the collet is moved relative to the collar from a non-locking position toward a locking position, the collar engages outer surfaces of the collet pieces and causes the collet pieces to move from a non-clamping position toward a clamping position. As the collet pieces are urged radially inward, they each pivot about a respective pivot axis. As the collet moves further toward the locking position and the collet pieces move further toward the clamping position, the pivot axis of each of the collet pieces radially moves relative to the collet body and the collar. A flaring mechanism moves a flaring mandrel towards the end of the tube when the collet is clamped, whereby the mandrel engages and flares the end of the tube.
