Description

Kink between pinch roll and finishing mill
Technical field
The utility model belongs to technical field of metallurgical equipment, relates in particular to auxiliary finishing mill in hot continuous rolling steekle mill unit.
Background technology
During China's metallurgy industry is produced, steekle mill unit is a kind of rear hot continuous rolling technology of sending out.The steekle mill unit of prior art, because equipment composition is limited, has limited production capacity raising.For utilizing to greatest extent steekle mill, can, on existing rolling line basis, after steekle mill, set up several finishing mills, reduce rolling pass to improve production capacity.Therefore need to before mm finishing mill unit, arrange and pinch and guide device, enter finishing mill for pinching band steel, and bear tension force, prevent from being with steel perk to damage simultaneously and batch furnace shell.
Summary of the invention
The purpose of this utility model is to provide a kind of looper between steekle mill and mm finishing mill unit, solves the problem that pinches of setting up finishing mill after steekle mill.
The technical solution of the utility model is: kink between pinch roll and finishing mill, comprise support, loop back roll, kink frame, kink cylinder, it is characterized in that: described support comprises base plate, guide beam, transmission side bearing and fore side bearing, described base plate is a flat board, described transmission side bearing and fore side bearing are the bearings of two settings, transmission side bearing and fore side rest base are fixed on base plate, guide beam is fixed on the base plate between transmission side bearing and fore side bearing, and two ends are fixedly connected with fore side bearing with transmission side bearing; Described kink frame is axle shape frame, axle shape frame two-end part is provided with swing arm, and described swing arm is strip flat board, and swing arm top is provided with bearing block, swing arm lower end and kink frame gun iron link, kink frame two ends are separately fixed on transmission side bearing and fore side bearing by bearing and bearing block; Described kink cylinder is fixedly connected on base plate, and the piston rod of kink cylinder is connected with kink frame one end with jointed shaft by eccentric stiffener, and the flexible kink frame that makes of kink cylinder piston rod rotates between 0 °~61 °, and kink cylinder is connected with hydraulic system; Described loop back roll is the hollow roll of two ends tape spool; Loop back roll two end axles is supported on respectively on the bearing block on swing arm top by bearing.Hydraulic system drives kink cylinder flexible, drives the rotation of kink frame, and the rotation of kink frame drives loop back roll to do the upper and lower swing of arc by swing arm, eliminates the kink amount with steel.
Kink between pinch roll described in the utility model and finishing mill, is characterized in that described kink frame fore side end is provided with the angular displacement sensor that detects loop back roll position, and angular displacement sensor is connected with hydraulic control system.Learn loop back roll position by angular displacement sensor, learn and maintain constant-tension rolling by regulator solution pressing system by strip tension through calculating, absorb the cover quantitative change that tension fluctuation produces.
Kink between pinch roll described in the utility model and finishing mill, is characterized in that the bearing at described kink frame and loop back roll two ends is self-aligning roller bearings.
The beneficial effects of the utility model are: can, on existing rolling line basis, set up finishing mill after steekle mill, reduce rolling pass to improve production capacity, utilize to greatest extent steekle mill.
Accompanying drawing explanation
