PURPOSE: An apparatus for lubricating chocks of reinforcing roll for cold rolling is provided to supply lubricant according to rolling speed by installing cam guide at the roll neck of the reinforcing roll and improve lubrication effect of bearing by discharging the collected iron pieces after collecting iron pieces in the lubricant using electromagnet. CONSTITUTION: The apparatus for lubricating chocks of reinforcing roll for cold rolling comprises a reinforcing roll bearing part(110) comprising a circular pipe(23) on the inner circumferential surface of which a plurality of first pipes(24) are formed, a cam guide(21) both side parts of which are contacted with a pair of bearing blocks(4) connected to the first pipes(24), and a chock block(2) for receiving the bearing blocks(4) so that the reinforcing roll bearing part(110) is installed at both side parts of the reinforcing roll; a lubricant injection part(120) comprising a ball unit contacted with guide groove formed on the cam guide(21) of the reinforcing roll bearing part(110), first cylinder body(45) for receiving first piston, second piston(65) received into a pair of second cylinder bodies(66), second clamping bar fixed to a fixed block, and fourth pipe contacted with the circular pipe(23) of the reinforcing roll bearing part(110); and a lubricant filtering part(130) comprising a circular filter clamped to the first cylinder body(45) of the lubricant injection part(120), an electromagnet(87) horizontally moved with being screw connected to screw bars, drain cases(92) a pair of which are penetratingly connected to both sides of the lower part of lubricant case(94), and a driving motor axially connected to the screw bars.
