WORKING LINE OF TUBE COLD ROLLING MILL

摘要

FIELD: rolled tube production, namely modified working line of tube cold rolling mill. ^ SUBSTANCE: working line of tube cold rolling mill includes rolling stand with movable cartridge having rolling rolls with variable cross section grooved passes; stationary housing; drive unit for reciprocation motion of cartridge; front and intermediate chucks with spindles providing rotation of tube and blank in rolling line. Stationary housing includes foundation, lid and vertical struts joining foundation with lid. Vertical struts of stationary housing are mounted along rolling line. Spindles of front and intermediate chucks are mounted coaxially one to other and to grooved passes of rolling rolls in vertical struts of stationary housing. ^ EFFECT: lowered metal consumption of working line of tube cold rolling mill due to mounting of front and intermediate chucks in struts of rolling stand. ^ 1 dwg
