Abstract:
A process for manufacturing a connecting rod, comprising:placing a heated perform suitable for being formed into the connecting rod into a closed forge die; forging the heated perform in a first forging operation while the heated perform is at a forging temperature to form an as-forged connecting rod having vertical flash extending therefrom; placing the as-forged connecting rod into a second forge die and forging the vertical flash in a second forging operation while the as-forged connecting rod is at a temperature approximately equal to the forging temperature, the second forging operation comprising folding the vertical flash onto the as-forged connecting rod and subsequently forming a radius in the vertical flash; removing the as-forged connecting rod from the second forge die; and machining the as-forged connecting rod to predetermined dimensions.
