Description

Technical Field

[0002] For the processing of hot-rolled plates, the plate coils are sequentially uncoiled, leveled, sheared and stacked to achieve slitting and flattening of the plates. Leveling is divided into coarse leveling and fine leveling. The plates are transported between various equipments through various roller racks and rollers. In the shearing process, the shearing is carried out by the cooperation of the lifting upper knife seat and the fixed lower knife seat, and a flip roller is set at the post-shearing position to support and guide the plates before shearing. During the shearing process, the roller needs to be flipped close to one end of the shearing machine to create a height difference between the end of the roller and the shearing point, which is used to make way for shearing and reset after shearing.
