Analysis of technological procedures for forging of stroke on large crankshafts

Popis výsledku v původním jazyce

Technology of forging of (strokes) central parts of large crankshafts by bending and die forging was verified on a scale model 1:15. The analyses were focused on the shape of forging, filling of die and surface defects. On the basis of obtained results new shape of the preform was proposed in such a way that the forging shape corresponds to dimensions on the drawing. Results of simulation have proved that the above mentioned defects could be eliminated by the new shape of the preform. Apart from that the required deformation force at bending was reduced only to 72 %, and at the same time mass of the perform was reduced by 15 %. Optimal shape of the preform may be applied to the existing technological procedure of forging. The obtained findings may be used for an optimisation of forging procedure also of other types of central parts of crankshafts.
