Description

An all-in-one machine for feeding and straightening cold-rolled steel coils

technical field

The invention relates to the field of straightening devices for cold-rolled steel coils, in particular to an integrated machine for feeding and straightening cold-rolled steel coils.

Background technique

Cold rolling is made of hot-rolled coils as raw materials, which are rolled below the recrystallization temperature at room temperature. Cold-rolled steel plates are steel plates produced through cold-rolling processes, referred to as cold plates. The thickness of the cold-rolled sheet is generally between 0.1--8.0mm, and the thickness of the cold-rolled sheet produced by most factories is less than 4.5mm. The thickness and width of the cold-rolled sheet are determined according to the equipment capacity of each factory and market demand. Cold rolling is a steel plate in which the steel plate is further thinned to a target thickness at room temperature or below the recrystallization temperature. Compared with hot-rolled steel sheets, the thickness of cold-rolled steel sheets is more accurate, and the surface is smooth and beautiful. Cold-rolled strips are widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans, etc.

In the flattening process after rolling, the steel plate needs to be straightened by a straightening machine in order to meet the flatness requirements of the final use, improve the performance and coating quality of the steel plate, and improve the output and productivity of the flattening process. during the rolling process. A series of shape defects may occur on the strip. There are two main forms, the first is the difference in surface area from face to face of the steel plate. Such as residual deformation after coiling or sickle bend and transverse scoop; the second is the difference in the length of the steel plate, such as side waves (unilateral or double-sided waves), middle waves, longitudinal warping and twisting.

The existing Chinese patent with the publication number CN102794332A discloses a rear-mounted improved concave-convex roller straightening machine for steel plate turtle back defects, which belongs to the technical field of metal coil processing equipment. Including raceway table, frame, upper feed roller, lower feed roller, straightening transition convex roll, straightening transition concave roll, straightening convex roll, straightening concave roll, upper discharge roll, The lower discharge roller, four pairs of oil cylinders, and the driving device of the inlet and outlet rollers. Straightening rolls include convex rolls placed above the steel plate and concave rolls placed below the steel plate. Four pairs of lifting cylinders adjust the reduction of the upper feeding roller, straightening transition convex roller, straightening convex roller, and upper discharging roller according to the thickness of the steel plate and the degree of turtle back.

Though above-mentioned this steel plate tortoise defect post-mounted improved concave-convex roller straightening machine can realize the straightening of steel plate tortoise defect flexibly and effectively. It is configured after the steel plate shearing stage of the steel coil straightening and shearing production line, which can improve the flatness of the steel plate to a certain extent, but because the concave-convex roller is used for straightening, the thickness of the straightened product may not be the same, and the straightening effect is not ideal. , and in the straightening of steel coils, the automatic feeding of steel coils cannot be realized.
