Method for Fracture Splitting a Connecting Rod and Corresponding Device

摘要

A method and a device for fracture splitting a connecting rod and a connecting rod formed therefrom are provided, in which a force exerted on an outer rim of an eye of the connecting rod by a separating tool is generated by an electromagnetic force. The separating tool includes at least two separating members inserted into the eye, and the electromagnetic force is generated by displacing the at least two separating members away from each other inside the eye in response to application of the electromagnetic force. The electromagnetic force may be generated by passing current through coils positioned between the at least two separating members in a manner that causes the coils to repel one another, preferably with a pulse duration of less than 100 microseconds, in order to minimize plastic deformation at the fracture locations.

主权项

1. A method for fracture splitting a connecting rod, comprising the acts of:
inserting a separating tool including at least two separating members within an outer rim of an eye of the connecting rod; generating an electromagnetic force causing the at least two separating members to repel one another so as to generate a mechanical separating force acting on the outer rim of the eye of the connecting rod.
