Multistage ring rolling machine for work pieces

摘要

The ring rolling machine has a shaping roll and a mandrel roll on a rolling spindle. The mandrel roll can be adjusted by means of a roll carriage and support rolls at the side of the work piece. There are several shapings, one behind the other, on the rolling tools, namely the shaping roll (1.8) and the mandrel roll (1.1). These comprise roll profiles (1.5,1.6) and mandrel profiles (A, B), to create successive intermediate forms after axial shifting.
