Method and devices for forging single crank throws of semi-built up crankshafts

摘要: A method and an apparatus for forging single crank throw elements comprising upsetting a rough piece in ring-segment compression die to form blank having opposite shoulder portions with narrowing connection portion, the portion from both central narrowest section. The is placed resting against inclined surfaces of such that clear spaces are formed between surfaces. force applied direction perpendicular thereto deform fill while concurrently forces portion. by laterally driving holder towards one another wedged element which driven press. supported articulated links pivotably mounted on fixed structure.
