Roller on-line cross mechanism of PC (polycarbonate) rolling mill

Abstract

The invention discloses a roller on-line cross mechanism of a PC rolling mill, which comprises a roller, a first bearing support, a second bearing support and a rolling mill rack, wherein one end of the roller is connected with the first bearing support, and the other end of the roller is connected with the second bearing support; a plane swing mechanism is arranged on the first bearing support and is tightly contacted or connected with one end of the rolling mill rack; and a plane deflection mechanism is arranged on the second bearing support and is tightly contacted or connected with the other end of the rolling mill rack. The roller on-line cross mechanism of the PC rolling mill can achieve on-line cross adjustment without a halted state of a production line.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an online crossing mechanism for rolls of a PC rolling mill. Background technique [0002] Since Japan successfully developed the HC rolling mill in the early 1970s, various countries in the world have carried out extensive research on flatness control technology, and successively developed a series of new rolling mills and new technologies for flatness control such as UC, HCW, VC, CVC, and PC. Good results have been achieved in practice. Compared with other shape control technologies, the technology of roll cross control of shape (such as PC mill) has the widest crown control capability, easy to adjust roll shape, no complicated roll shape curve, and is not limited by roll neck strength and It is easy to realize the advantages of free rolling and large reduction rate. With the rapid development of hot rolling technology, the requirements for plate thickness and c...

AI Technical Summary

Problems solved by technology

If the cross mechanism of this structure needs to be adjusted, due to the large rolling force applied by the PC rolling mill when rolling steel, a large friction force is formed between the frame and the bearing seat, and this friction force becomes the PC rolling mill roll on-line The resistance when crossing is limited by the crossing thrust (if excessive crossing thrust is used, there will be higher requirements on the crossing mechanism and the driving motor), the above crossing mechanism cannot realize online crossing adjustment through the crossing angle adjustment mechanism

Therefore, the current crossing angle of the rolls needs to be adjusted when the production line is stopped, and the steel rolling will be carried out after the crossing angle is adjusted. The consequences of this situation will directly reduce the production efficiency
