Abstract:
A process for producing a connecting rod for piston-operated machines having a split extending through a big end having an eye, the process comprising the following steps taking place chronologically:a) mechanical finishing an un-machined die cast part except for the next process steps,b) in an area of an intended split of the big end, forming notches on an interior circumference of the big-end's eye and on an exterior area of the big end opposite the interior notches to weaken material there between, andc) breaking the big end along a breaking line of separation defined by the notches and simultaneously forming, by the breaking, opened-out areas on an interior side of the big-end's eye to be used as bore reliefs using a tool interior to the eye and shaped to create forces substantially transverse to and along the breaking line to produce the breaking and forming the opened-out areas respectively.
