METHOD FOR MANUFACTURING SIDEWALL SHEETS OF THE GRAIN STORAGE SILOS

摘要

The present invention provides a method for producing a wall plate 10 of the silo by using the plate : a rectangular plate on the edge of the bolt hole (10a) for processing a punching step (S10); Bending the punched plate material for forming the surface in a wave (10b) in the press (20) step (S20); And is characterized in that comprises a bending step (S30) for forming a wall plate 10 of the finished product in the bending roller 30 to the bent plate . At this time , the bending step (S20) is processed by one pitch by the reference pins 25 of the press (20). ; Accordingly, the fixed investment cost reduction in mass production and high quality field for producing a silo and there is an effect that can increase the productivity maintenance .
