Efficient roll changing system of wide and thick plate straightener

Abstract

The invention discloses an efficient roll changing system of a wide and thick plate straightener. The system comprises a memorial archway (5), a roll changing driving device (9), a main transmission connecting shaft (8) and a connecting shaft adjusting mechanism (1), a roll system device (3) is arranged in the memorial archway (5) and comprises straightening rolls (31), the roll changing driving device (9) is located on the operation side of the memorial archway (5), the main transmission connecting shaft (8) and the connecting shaft adjusting mechanism (1) are located on the transmission sideof the memorial archway (5), one end of the main transmission connecting shaft (8) is connected with one ends of the straightening rolls (31), the other end of the main transmission connecting shaft(8) is connected with a driving mechanism, and the connecting shaft adjusting mechanism (1) can adjust the position of one end of the main transmission connecting shaft (8) in the vertical direction.The efficient roll changing system of the wide and thick plate straightener has the advantages of fast roll changing rhythm, stable process, safety, reliability, high automation degree and the like.

Description

technical field [0001] The invention relates to the field of metal plate processing equipment, in particular to a high-efficiency roll changing system for a wide and thick plate straightening machine. Background technique [0002] The straightening machine is one of the main finishing equipment on the wide and thick plate production line, which is used to straighten the steel plate to make its flatness meet the national standard and customer's requirements. In order to improve the plate shape, improve product quality and production efficiency, modern straightening machines adopt various technologies and means. The straightening process of the steel plate is the process of bending and springing multiple times. After several times of bending and springing by the straightening roller, the straightness of the steel plate must meet the standard requirements. Due to the thickness and The original bending is not the same, so the required number of bending times and bending degree ...

AI Technical Summary

Problems solved by technology

The roll changing system of the pre / heating leveler is characterized by a three-layer locking mechanism, which has the advantages of reliable locking and accurate positioning, but the locking mechanism of the middle layer requires manual loading and unloading and positioning operations, and the labor intensity of the workers is high. There are many potential safety hazards, and the time for changing rolls is long

The roll changing system of the cold leveler adopts a two-layer locking mechanism, which has a high degree of automation. In theory, the operation of the locking mechanism does not require manual assistance, but the structure of the universal joint shaft affects the layout of the locking mechanism. , which leads to the unsatisfactory locking effect of the locking mechanism. At present, some domestic wide and thick plate factories have modified this structure.

The roll changing system of the wide and heavy plate leveler designed by Siemens VAI (Vai Alpine) also belongs to the three-layer locking structure. The intermediate locking mechanism is improved to have a swing function, which shortens the roll changing time to a certain extent, but still needs Manual assistance, and because the position of the swing mechanism is fixed, and the intermediate locking mechanism not only swings but also needs to be lifted, so there are often faults such as jamming
