Abstract

PURPOSE: To mass-produce products with high accuracy by utilizing deformed trampet type members formed from cut steel plates having butterfly-shape.
CONSTITUTION: A steel plate 7 cut out in butterfly-shape is coldpressed by die- press and portions AWE, C-G to be jointed are welded, and thus, a cup-shaped member of a deformed trumpet-shape, an expanded portion having jointed protions 8 of which is like as being pressed in an up-and-down direction, is formed, and thereafter, portions EFGH are cut off, and thus, deformed trumpet type members are welded together so as to be symmetric in order to make a chock member 1, thereafter, semi-circular reinforcing ribs 4 and a fixing stand 5 are welded thereto. By this method, the deformed trumpet type members 2, 3, with stable and same shapes having few variations of the thickness of the plates because of the cold-pressing of the butterfly-shaped steel plate 7 previously cut so as not to create wrinkles of press works, may be mass-produced easily.
