WORKING FOR STEEL PLATE AND APPARATUS THEREOF

PURPOSE:To prevent the reduction of productivity due to the reduction of performance due to handling, temporary setting, staying, etc. by transferring a steel plate to be worked, in the longitudinal direction on a working line by a conveyor and executing continuous work by the equipment on the line. CONSTITUTION:When marking-off is completed, fixation is released, and a material (steel plate) 1 is fed onto a longitudinal cutting surface-plate by a roller conveyor 2, and the gas cutting in parallel to slow curve from on the both sides which is parallel to rails is carried-out on the right and left sides at a same time, and the material is fed into a width cutting machine 15. Then, the rear edge of the front plate material 1 and the front edge of the rear plate are worked at a same time, and after the front and rear edges of the material 1 are cut by an automatic gas cutting machine, a drilling basic plate 22 is fed from outside the line, and after the plate 22 is set onto the member 1, the plate 22 is transported towards a drilling machine 23 by the conveyor 2. Drilling work is carried-out onto the material 1 through the basic plate 22, and when drilling is completed, the material is transported into a primer exfoliation part by the conveyor 2, and the primer is exfoliated by a wire-brush roller, and work is completed.
