FIELD: rolled stock production, namely tube rolling mills for manufacturing seamless tubes, particularly arresting and regulating mechanism of rear table of helical rolling mill for tube producing.
SUBSTANCE: carriage with arresting head and with lock is mounted in housing. Said carriage supports mandrel stem with mandrel, screw mechanism for moving carriage and hydraulic cylinders for moving stem with mandrel during rolling process. Hydraulic cylinders are mounted in parallel relative to carriage at different sides from it coaxially to screws axes of mechanism for moving carriage. Rods of hydraulic cylinders through spherical step bearing assemblies are joined to carriage. Spherical supports coupled to spherical step bearing assemblies of screw mechanism for moving carriage are mounted on bodies of hydraulic cylinders.
EFFECT: improved operational reliability, increased useful life period of arresting and regulating mechanism for moving stem with mandrel during rolling process and of the whole equipment.
