Abstract

The invention discloses a five-roll metal plate and strip straightening machine, and belongs to the technical field of metal plate and strip straightening machines. The straightening machine comprises a power transmission device and straightening rolls, support rolls and a pressing device which are arranged in a frame. The straightening machine is characterized in that: a roll system structure consists of two upper straightening rolls and three lower straightening rolls staggered along a rolling center line, and the middle position above the two upper straightening rolls is provided with an upper support roll, the diameter of which is 3 to 5 times that of the straightening rolls. A lower support roll, the diameter of which is 3 to 5 times that of the straightening rolls, is arranged belowthe middle straightening roll of the three lower straightening rolls. Compared with the prior art, the straightening machine has the advantages of reasonable roll system arrangement, simple machine structure, small volume and light weight.

Description

technical field [0001] The invention belongs to the technical field of metal strip straightening machinery, and in particular relates to a five-roll metal strip straightening machine. Background technique [0002] At present, the straightening of metal strips at home and abroad is mostly carried out by the straightening rollers supported by multiple rows of support rollers to straighten the metal strips, such as figure 1 , figure 2 shown. The disadvantage of this structural form is that the structure is huge and complex, the equipment is large in size and heavy in weight, and the bearings of the back-up rolls are installed on the strip running line, so the working conditions are poor and easy to be damaged. Contents of the invention [0003] The object of the present invention is to provide a five-roll metal strip straightening machine, which can overcome the above-mentioned shortcomings in the prior art. [0004] The present invention is realized in this way, it compr...
