Abstract

PURPOSE:To facilitate the joining of mutual end faces and to reduce the price in manufacturing a box body by forming a projection simultaneously with rolling a projecting part plate thickness thinner than a metal plate by forming one part of the end edges of the metal plate and piercing the engaging hole with the recessed place engaging with the projecting part and the projecting part at the other end. CONSTITUTION:One part of end edges 3 of the metal plate 2 in the shape of developing a box body 11 is punched in uneven shape and subjected to pattern draw rolling as well with the plate thickness of the projecting part 4 being thinner than that of the metal plate 2. And simultaneously with this rolling a projection 5 is formed on the rolling face thereof. Also, simultaneous with this punching the other end 6 of the metal plate 2 is formed by punching and the recessed place 7 engaging with the projecting part 4 is formed by squeezing as well. Moreover, the engaging hole 8 projecting the projection 5 some to the opposite side face by penetrating it is pierced. The protruding part 9 by the punched rolling and squeezed piercing is press-cut as well as contour punching then. And at the bending stage it is bent adequately for forming a square cylindrical box body 11, the projecting part 4 and recessed plate 7 are engaged and the engaging hole 8 is penetrated simultaneously, the projection 5 projecting to the opposite side is squeezed and the engaged projecting part 4 and recessed place 7 are joined.
