Claims (1)

Способ изготовления коленчатого вала горячей объемной штамповкой из проката, при котором вначале поперечной глубокой прокаткой или другими способами формируют шатунные шейки коленчатого вала, придают при этом ориентированное окончательное положение поверхностным волокнам материала шеек, параллельное их осям, отличающийся тем, что в дальнейшем заключают шатунные шейки коленвала в замкнутые поверхности зажимных элементов и осуществляют гибку коленвала, далее выполняют формовку щек и противовесов в открытых штампах, при этом также удерживают коленчатый вал за окончательно сформированные шатунные шейки в упомянутых замкнутых поверхностях и исключают истечение материала в направлении, перпендикулярном наружной поверхности шеек.A method of manufacturing a crankshaft by hot die forging from rolled metal, in which the connecting rods of the crankshaft are first formed by transverse deep rolling or by other methods, while providing the oriented final position of the surface fibers of the neck material parallel to their axes, characterized in that they further comprise the connecting rod crankshaft journals into the closed surfaces of the clamping elements and carry out the bending of the crankshaft, then perform the molding of the cheeks and balances in open dies, while also rzhivayut crankshaft for finally crankpins formed in said closed surfaces and eliminates outflow of material in the direction perpendicular to the outer surface of the necks.
