Description

Technical Field

[0001] The invention relates to the field of automatic stacking of hot-rolled guide rail blanks in the metallurgical industry, and particularly designs a guide rail steel finishing system in the field of automatic stacking. Background Art

[0002] After the guide rail steel is rolled out from the rolling line, it is cooled on a cooling bed, straightened by a straightening machine, and cut to size to form guide rail blanks that meet national standards or market requirements. They are then sorted, organized, stacked, and packaged into bundles for easy storage and transportation.

[0003] The shape of the guide rail steel is irregular T-shaped, which is different from simple shaped steel. Its automatic sorting and automatic stacking technology needs further research and development.

The workers have high labor intensity, low efficiency, high production costs, and no safety guarantee.

[0004] The guide rail steel finishing process is divided into three sub-processes: steel separation, steel stacking, and shaping. The steel separation process mainly separates the grouped guide rail steel input from the rolling line into single pieces for stacking in the subsequent steel stacking process; the steel stacking process stacks the single guide rail steel after steel separation according to the stacking requirements. Generally, the guide rail steel stacking process is divided into several simple actions, and multiple execution units work together to complete the steel stacking task; the shaping process separates and shapes the stacked rows of guide rail steel according to the specified spacing for forward and reverse cross stacking.
