Rolling machine for hot-rolled sheets with excellent rolling assisting property

Abstract

A hot-rolled sheet coiling machine with better coil-helping performance has a reel, coil-helping rollers, swinging arms for supporting said coil-helping rollers, and hydraulic cylinders for driving said swinging arms. It features that 1-3 coil-helping roller are additionally used for increasing the points to where the pressure is applied, so improving its coil-helping performance.

Description

technical field

[0001] The invention relates to an improved coiler used in a thin plate rolling production line, which belongs to the technical field of plate rolling. Background technique

[0002] The steel billets are processed into thin strips after initial rolling, finishing rolling, and cutting to length, and then sent to the coiling facility through the conveying roller table, where they are coiled into standard coils with a certain thickness, and then bundled and packaged. After the process, it becomes the final product. The coiler used in the hot-rolled sheet production line is generally composed of a mandrel, a mandrel rotation drive, a coiling roll arranged around the mandrel, a swing arm where the roll is located, and a hydraulic cylinder that drives the swing arm. When the front end of the formed sheet strip enters the positions of the rolling rollers in turn, the hydraulic cylinders of the rolling rollers drive the rolling rollers to move closer to the mandrel ...
