Abstract
PURPOSE: To make a casing of an oil filled electrical apparatus light-weight and small sized by placing a corrugated side plate between the upper side plate of and the lower side plate of same casing to unite both into one body in a flat state, and bending said body with a large radius of curvature at the corner to form a casing.
CONSTITUTION: A flat corrugated side plate of sheet steel with approximately one half measurement l of the full casing inside measurement and the lap dimension Δl at the brim is provided. A flat sheet steel upper side plate 2 with the curled portion 2a at each end of the exposed corrugated section is welded with the lower side plate with the curled portion 3a in the same way as the upper side plate to form a side plate assemble body 1A. And the assemble body 1A is held maong the lower mold 8a to be the upper side plate female mold and the lower mold 8b to be the lower side plate female mold and the upper mold 9 to be the common male mold. And then, bend it into a L-shape giving a large radius to the curled portions 2a and 2b. Thereafter, two sets thereof are made a pair and they are assembled, given a joint welding at the lap portion lengthwise and are fitted with the bottom plate 4.
