Embodiment Construction

[0008] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0009] see figure 1 , the present invention provides a technical solution: a roll structure of a cold bending mill, including a first roll 1, a second roll 2, and a third roll 3 that are fitted through a gap, and the first roll 1 and the second roll 2 are set On the keyed shaft, the third roll 3 is arranged on the first roll 1, and the third roll 3 will not scratch the plate along with the passive rotation of the plate;

[0010] Further, the first roll 1 has ...

Abstract

The invention provides a roller structure of a cold bending rolling mill. The roller structure comprises a first roller (1), a second roller (2) and a third roller (3) which are in clearance fit. Thefirst roller (1) and the second roller (2) are arranged on a shaft with a key, and the third roller (3) is arranged on the first roller (1). The third roller (3) rotates passively along with a plate,and the phenomenon that the plate is scratched cannot be generated; and the rolling quality of the cold bending rolling mill is greatly improved, the roller structure is conveniently adjusted, and overall running of the unit is good.

Description

technical field [0001] The invention belongs to the technical field of rolling, and in particular relates to a roll structure of a cold bending mill. Background technique [0002] In the rolling process of the cold bending mill in the prior art, the integral roll is usually used, and the difference between the inner and outer diameters of the integral roll is relatively large, so the linear velocity difference is large, and sliding friction will be generated, which will cause serious scratches on the surface of the profile, thereby Produce waste or defective profiles, resulting in economic losses. Contents of the invention [0003] In order to overcome the above-mentioned technical problems, the technical solution adopted to achieve the above-mentioned purpose is: a roll structure of a cold bending mill, including a first roll, a second roll and a third roll through clearance fit, the first roll and the first roll The second roll is set on the shaft with key, the third ro...
