ABSTRACT:
A method for fracturing the cap and shaft of connecting rods manufactured by powder forging in which the cap or the shaft of the connecting rod is fixed on a support movable perpendicularly to the plane of fracture, the portion of the connecting rod not fixed on the support is held stationarily, and a straight central impact acting in the axis of symmetry of the connecting rod is applied to the support in the direction of fracture.
