Description
Technical Field
The invention belongs to the technical field of rod and wire continuous rolling production line equipment, and relates to a control method and device for a rear turning plate of a flying shear in a rod and wire continuous rolling production line.
Background
In a rod and wire continuous rolling production line, flying shears are one of the key devices of the production line. The main functions of the flying shear include head cutting, tail cutting, accident breaking and the like of rolled pieces. The function of the turning plate after shearing is to match the head cutting, tail cutting and breaking actions of the flying shears to complete the head cutting, tail cutting or breaking functions of the flying shears to the rolled piece. When the head cutting function of the rolled piece is executed, the cut rolled piece is guided into a hopper positioned below a rolling line and the cut rolled piece is guided into a rolling channel by the rear turning plate in the process of running from a high position to a low position. The process that the rear turning plate runs from a high position to a low position is a fixed process, and once the action of the rear turning plate is started, the rear turning plate runs at a set running speed and position. If the turning plate starting control has deviation, the production interruption accident that the cut end is led into a rolling line (when the starting is advanced) or the rolled piece after the cutting end is led into a hopper (when the starting is delayed) can be caused. Therefore, how to control the accurate starting of the turning plate after the shear is a key technology for finishing the head cutting function of the flying shear.
At present, the control of starting the plate turnover after shearing is realized by tracking the head position of a rolled piece, and the tracking of the head position of the rolled piece is calculated by a PLC control system according to the theoretical speed of the rolled piece by detecting the state of a detection element arranged on site. The control technology has the following defects: the stable state and the detection precision of the on-site detection element can fluctuate along with the change of production conditions (on-site environment, temperature of a rolled piece, size of the rolled piece and the like), so that the head tracking of the rolled piece can be unstable, the plate turning action after shearing can be advanced or delayed, the production interruption accident can be caused, and the continuous and stable continuous rolling production can be favorably realized.
