Board rolling device

Abstract

The invention provides a board rolling device, which comprises a working roller, a supporting body and a driving mechanism, wherein the supporting body is used for supporting and limiting the working roller, and the driving mechanism is used for driving the working roller. The supporting body (1) is in face contact with and is matched with the working roller (2) in a sliding way, the contacting length is not less than the width of a rolled board (3), and the rigidity of the supporting body (1) is larger than that of the working roller (2). The board rolling device provided by the invention has simple structure, small size and low cost, and is suitable for rolling a thin board, a thin belt, a thin film or a wide board.

Description

technical field [0001] The invention relates to a plate rolling device, in particular to a thin plate, thin strip, film or wide plate rolling device, which belongs to the field of mechanical engineering. Background technique [0002] Generally, large-diameter two-roll or four-roll rolling mills are mostly used for plate rolling. For thin plate rolling, because the elastic flattening of the roll is proportional to the diameter of the roll, if a large-diameter two-roll mill is used to roll the thin plate, the elastic flattening value of the roll itself is often greater than the reduction of the plate to be rolled . Therefore, when the roll material is constant, to reduce the elastic flattening value of the roll, the roll diameter must be reduced. On the other hand, when the roll diameter is large, the contact area between the roll and the plate is large, and the rolling force required for rolling the plate is also large; therefore, to reduce the rolling force, the roll diame...
