Linkage adjusting mechanism for plate rolling machine working rollers

Abstract

The invention discloses a linkage adjusting mechanism for plate rolling machine working rollers. The linkage adjusting mechanism comprises a side roller linkage mechanism body. The side roller linkage mechanism body comprises a first linkage arm and a second linkage arm. The first linkage arm is clamped into the second linkage arm and is in rotating connection with the second linkage arm. The first linkage arm and the second linkage arm are provided with moving bases in an embedded mode correspondingly. Side roller bases are formed in the corresponding moving bases. The first side roller and the second side roller are installed in the corresponding side roller bases. A lower roller base is arranged at the coincided position of the first linkage arm and the second linkage arm, and the lower roller is installed in the lower roller base. The moving bases are connected with the first linkage arm or the second linkage arm through corresponding moving base drive mechanisms. The linkage adjusting mechanism for the plate rolling machine working rollers is compact in structure, stable and reliable. Meanwhile, the first side roller and the second side roller can be adjusted in the front-back direction and the up-down direction, and the flexibility, adaptability and universality of equipment are enhanced; and meanwhile, the adjusted first side roller and second side roller are positioned, and thus the rolling precision is further improved.

Description

technical field [0001] The invention relates to the field of plate rolling machines, in particular to a linkage adjustment mechanism for working rolls of the plate rolling machine which enhances the flexibility, adaptability and versatility of the plate rolling machine. Background technique [0002] With the rapid development of national defense and civilian industries, the market demand for various circular cylinder parts is increasing. The four-roller plate rolling machine is more and more favored and affirmed by users for its high rolling precision, fast efficiency, and small plate end straight edge. The traditional four-roll plate rolling machine can be divided into linear and arc type four-roll plate rolling machines according to the different ways of lifting the side rolls. [0003] For example, Chinese patent CN203991812U discloses a four-roller plate bending machine that linearly pushes the side rollers to move in an arc, including upper rollers, lower rollers, side...

AI Technical Summary

Problems solved by technology

[0005] 1. The motion accuracy and precise positioning of the side roller lifting are relatively poor;

[0006] 2. During the rolling process of the cylinder, it is necessary to continuously switch the action of the work roll, and the operation is relatively cumbersome and slow

However, the technical solution disclosed in the Fan Ming patent cannot realize the rolling of the tapered cylinder, and the scope of application and versatility still need to be improved.
