Abstract

PURPOSE: To eliminate loading of pin-holes of can body and make inspection of nonconforming products sure and easy in manufacturing a cylindrical can by high speed ironing press by making the diameter of the cylindrical can larger beforehand and drawing to the dimension of the can body at the time of secondary drawing.
CONSTITUTION: When manufacturing a metallic plate to a cylindrical can by press, a cylindrical body 2 larger in diameter C than the dimension B of a flange 5 for seaming is made beforehand by drawing. Next, after drawing the diameter C to the dimension A of the can body in secondary drawing, a cylindrical can body of desired dimension is manufactured by cutting off unnecessary part 5. In this case, generation of internal stress is small since the diameter A is made by compression from the large diameter C, and loaded pin-holes are opened to make visual inspection of nonconforming products and inspection in heated water by pin-holes possible.
