Rolling machine

Abstract

The invention relates to a rolling machine. The rolling machine comprises a frame, an upper roll set and a lower roll set. The upper roll set and the lower roll set are symmetrically arranged on the frame; the upper roll set comprises a first upper roller, a second upper roller, a third upper roller, a fourth upper roller, a fifth upper roller and a sixth upper roller; the lower roll set comprisesa first lower roller, a second lower roller, a third lower roller, a fourth lower roller, a fifth lower roller and a sixth lower roller; the diameter of the first upper roller is separately smaller than those of the second and third upper roller, and the diameter of the first lower roller is separately smaller than those of the second and third lower rollers; the first upper roller and the firstlower roller are arranged opposite to each other and lean against each other. The rolling machine is provided with the six rollers for the upper roll set and the lower roll set, separately, so that the pressure can be distributed in a balanced manner; as the diameters of the first upper roller and the first lower roller are relatively small, the rolling precision is increased favorably; a steel disc which is relatively thin in thickness is rolled conveniently, and the rolling effect of the steel disc which is relatively thin in thickness is more excellent.

Description

technical field [0001] The invention relates to the technical field of rolls, in particular to a roll machine. Background technique [0002] Stainless steel sheets are widely used in industries such as machinery, electronics and automobiles. The steel sheet must be rolled by a rolling mill during production. Through the rolling of the roller machine, the surface of the steel sheet has a high flatness and a strong hardness. [0003] The traditional roll mill adopts the structure of six-roll and four-roll. Taking the four-roll structure as an example, AGC is used to press down the roll. Three rolls are set in the city, and the steel sheet surface flatness of the traditional six-roll and four-roll structure roll mill rolls is poor, and it is impossible to roll the thinner steel sheet. Contents of the invention [0004] Based on this, it is necessary to provide a roll machine. [0005] A roll machine, comprising a frame, an upper roller group and a lower roller group, the ...
