For above-mentioned situation, be necessary design and installation sheet material nose smoothing device before thermal straightening machine, solve odd-numbered pass and finish the rolled plate nose to the straightener restricted problem of nipping, thereby for mill milling passage choose reasonable provides greater flexibility, be conducive to save energy and reduce the cost, raise the efficiency according to rolling model optimization and minimizing rolling pass.

The utility model content

Technical problem to be solved in the utility model provides a kind of cut deal thermal straightening front spring nose pressuring flat device, this device can flatten the hot rolled steel plate nose, reduce the steel plate nose to the impact of smoothing roll, optimize simultaneously and reduce rolling pass, energy-saving and cost-reducing and raising Heavy Plate Production line milling train production efficiency.

The technical scheme that solves the problems of the technologies described above is:

A kind of cut deal thermal straightening front spring nose pressuring flat device, comprise ram, portal frame, fixed pulley, haulage cable, cylinder, reductor, motor in its formation, portal frame is comprised of two root posts and the crossbeam that are installed in the roller-way both sides, on the portal frame crossbeam fixed pulley is installed, ram is positioned at the below of portal frame crossbeam, the ram bottom surface is relative with steel plate transport roller-way upper surface, one end of haulage cable is connected to the ram upper end, the other end is connected with reductor by fixed pulley, cylinder, and reductor is connected with motor.

Above-mentioned cut deal thermal straightening front spring nose pressuring flat device, on the described portal frame leading truck is installed, the leading truck bottom is fixedly connected with the ram two ends, and vertical guide rail is arranged on the portal frame crossbeam, the leading truck both sides are embedded in the portal frame beam guideway, and leading truck and guide rail are sliding-contact.

Above-mentioned cut deal thermal straightening front spring nose pressuring flat device is equipped with respectively approach switch and lead limit switch on described cylinder and the leading truck, approach switch is connected with motor control assembly with lead limit switch.

Useful result of the present utility model is:

Ram of the present utility model moves up and down under the traction of motor and haulage cable, and ram is pressed on the steel plate nose position, and steel plate produces plastic deformation under ram gravity and the acting in conjunction of original roller-way support force, and nose is driven plain.The utility model is simple in structure, easy to operate, flatten the respond well of nose.The utility model has remedied the instrument that does not have professional online flattening steel plate nose, not only solved the shock problem of steel plate nose to smoothing roll, and can make the following sheet material of mill milling thickness 40mm realize that strange passage is rolling, reduce by 2 passages than former rolling procedure, reduced significantly the power consumption of rolling mill main motor and electric machines for roller, improved Heavy Plate Production line milling train production efficiency, for enterprise has created very large economic benefit.
