METHOD AND UPSETTING DEVICE FOR MANUFACTURING OF LEDGED PARTS, SUCH AS SHAFTS AND RODS Russian patent published in 2017 - IPC B21K23/04 B21K1/46 B21J13/02 B21J5/08

Abstract RU 2614224 C2

FIELD: metallurgy.

SUBSTANCE: invention refers to pressure processing of metals and can be applied in manufacturing of parts in the form of a rod with flanges. Heated ingot is deformed in a moulding machine in stages. At the first stage of deformation, a rod workpiece is obtained with a diameter equal to finished part diameter. At least one next stage involves upsetting of at least one flange on the rod workpiece, with the final flange diameter exceeding the rod workpiece diameter.

EFFECT: possible manufacturing of parts with improved parameters out of ingots of different sizes.
