Abstract
PURPOSE: To make possible working inexpensively and make regeneration easy even with relatively hard plate material such as iron plate by pressing the required portions of the cover with the upper and lower dies corresponding to the specified shape of the opening piece and extruding and molding upward the portions corresponding to the opening piece.
CONSTITUTION: The required portions of a cover body 1 are pressed by using the upper and lower dies 5, 6 corresponding to the shape and size of a opening piece 2, by which the portions corresponding to the opening piece 2 are extruded and molded upward. Thence, the cover body 1 is placed on the lower die 9 having a concave insertion groove 8 in the portion corresponding to the circumferential edge part of the opening piece 2 on the top face in such a manner that the abovementioned opening piece 2 comes inward of the concave insertion groove 8 and when it is pressed with the upper die 10 of a flat bottom face, the connecting piece 7 is folded downward in V-form from its approximate central part by the lateral component of force along with its taper and plunges into the concave insertion groove 8, by which the thin-walled cutting guide line 4 is formed. The depth of this cutting guide line 4 and the thickness of the connecting piece 7 may be set easily at desired values even with iron plates of relatively poor workability by setting working conditions to required ones.
