Definitions

twisting operation consists of making a torsion in the crankshaft with respect to its longitudinal axis in order to place each crankpin in the corresponding angular position.
the crankshaft twisting equipment used today is formed primarily by a hydraulic press with a main cylinder, the corresponding frame thereof, an upper base plate and a lower base plate.
the equipment for twisting crankshafts (A) proposed by the invention comprises at least three twisting modules (1); in the cases depicted in the drawings there are three, but it is also contemplated that it can comprise five.
each twisting module (1) are arranged on a supporting element (2) that can rotate independently with respect to an axis of rotation (3) coinciding with the longitudinal axis (A') of the crankshaft (A) when said crankshaft (A) is arranged in the equipment.
