Abstract:
A device for breaking an enlarged bearing portion of a connecting rod along a predetermined break line to divide the enlarged bearing portion into a main body portion and a bearing cap portion, comprising:a longitudinally movable pressing mechanism for engaging the bearing cap portion of the connecting rod; a stationary clamping mechanism for engaging a main body portion of the connecting rod, said pressing mechanism and said clamping mechanism being longitudinally spaced apart to receive and secure the enlarged bearing portion of the connecting rod; a split mold having two mold parts and located to extend through a central aperture in the enlarged bearing portion of the connecting rod when the rod is secured; a pressurizing mechanism located between said pressing mechanism and said clamping mechanism and including first and second opposed, laterally spaced, pressurizing caps adapted to engage opposite sides of the enlarged bearing portion of the connecting rod when the rod is secured, said caps defining opposite ends of the predetermined break line so that the break line extends between said pressing mechanism and said clamping mechanism and through the enlarged bearing portion; and a wedge for separating the two mold parts of said split mold to break, along the predetermined break line, the enlarged bearing portion of the connecting rod secured by said clamping mechanism and said pressing mechanism.
