Control system and control method for cooling bed steel unloading system

Abstract

The invention belongs to the technical field of controlling a cooling bed steel unloading system, and particularly relates to a control system for a cooling bed steel unloading system. The cooling bedsteel unloading system comprises a plurality of cooling bed steel unloading devices. The cooling bed steel unloading devices are all connected to an outdoor control system. The control system comprises a first solid state relay, a second solid state relay, a second power supply and a PLC. The PLC is respectively connected to the first solid state relay and the second solid state relay. The firstsolid state relay and the second solid state relay are connected with a first solenoid valve installed on a hydraulic cylinder (5) in each cooling bed steel unloading device, so as to drive the corresponding hydraulic cylinder (5) to expand and contract, then drive a mechanical linkage mechanism (6), and control a lifting baffle (2) to reach the corresponding high gear and low gear.

Description

technical field [0001] The invention belongs to the technical field of controlling a steel unloading system on a cooling bed, and in particular relates to a control system and a control method for a steel unloading system on a cooling bed. Background technique [0002] The cooling bed is an important auxiliary equipment in the bar production workshop. The steel unloading system on the cooling bed is the tail of the finished nth bar and the head of the n+1th bar that are cut into multiple lengths by flying shears and transported at high speed. Separation, and sequentially braked and transported to the cooling bed. [0003] With the improvement of the production capacity of the workshop, the steel unloading system on the cooling bed needs to be used frequently, which leads to frequent failures of the steel unloading system on the cooling bed. Longer downtime of bed equipment. Due to the continuous work and the frequent action of the relay in the steel unloading system on the...

[0003] With the improvement of the production capacity of the workshop, the steel unloading system on the cooling bed needs to be used frequently, which leads to frequent failures of the steel unloading system on the cooling bed. Longer downtime of bed equipment

Due to the continuous work of the relay in the steel unloading system on the cooling bed and the frequent action of the steel unloading system on the cooling bed, the relay in the steel unloading system on the cooling bed heats up, making the contacts of the relay sticky.
