FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, namely, to pipe rolling. Case accommodates forming rolls with shaping disks, and forming roll drive made up of levers. Note here that said bell cranks incorporate return springs and two adjustable thrust elements arranged ahead of and behind forming roll along direction of tube motion to turn in plane aligned with tube axis. Note also that shaping disk axis is shifted relative to level turn axis along direction of tube motion.
EFFECT: easier conversion of draw bench.
