Technical Field

The invention belongs to the technical field of plate processing equipment, and particularly relates to an automatic plate laser processing production line.

Background

At present, in order to improve the processing efficiency and the processing precision of metal plates and reduce the labor intensity of workers, most manufacturers adopt an automatic production line or a semi-automatic production line to sequentially perform the processing procedures of uncoiling, cutting, bending, welding and the like on the metal plates, and process the metal plates into required finished products or semi-finished products. However, in the actual production process, since part of the finished metal plate needs to be made of two or more plates with different thicknesses and materials, the production process needs to involve plates with various specifications and types. The existing plate production line has unidirectionality and unicity, namely the existing plate production line can only feed and process plates along a specified feeding direction, can only produce plates of one specification in the production process, and cannot flexibly increase raw materials in the production and processing process, so that the existing plate production line cannot process finished products of the metal plates at one time when processing the finished products of the metal plates, thereby prolonging the processing time in the whole production process and reducing the processing efficiency.
