Technical Field

The invention belongs to the technical field of steel industry equipment, and relates to an auxiliary device for multi-length steel division of bar cold bed finished products.

Background

The steel feeding device is one of important devices of a bar production line, and rolled pieces are rolled out from finished product holes and then are thrown to a steel cooling bed straightening plate through a water penetrating device → a double-length flying shear → a quick guide section conveying roller way in front of a cooling bed → a quick cooling bed section conveying roller way → the steel feeding device. The lifting apron board is mainly used for braking bars running on the roller way, plays a role in steel separation while braking, and unloads the braked bars into a cooling bed straightening plate for straightening. During multi-segmentation rolling, due to the reasons that the rolled finished product is high in temperature, small in steel diameter, soft in multiple length of the upper steel finished product and the like, steel splitting is not thorough or the steel splitting process is delayed, multiple length rear-end collision of the upper steel finished product on a cooling bed is caused, the yield and the operating rate are directly influenced, and therefore the passive situation that a finished product multiple length steel splitting auxiliary device is required to be designed to twist is urgently needed.
