FIELD: process engineering.
SUBSTANCE: invention relates to pipe rolling and can be used at perfection of working line of cold pipe rolling Pilger mill. Mill working line comprises moving cartridge with working rolls, moving bearing bed with support rails, drive of their reciprocation and leverage for timing of cartridge and bed motion composed of levers and links connecting said cartridge and moving bed with said drive. Mill fast operation results from articulation of link with moving bearing bed and its connection with leer via bearing support at camshaft fitted at lever top part and equipped with drive that allows locking at whatever position while cartridge and lever are coupled with the drive of displacement by independent links.
EFFECT: notable decrease in clearances in timing gear.
