Abstract
PURPOSE: To achieve lower cost, more lightweight product and less defective occurrence by forming a metal flat plate to a circular truncated once shape then cutting of its bottom and opening to provide openings at both ends, forming flange parts at the both parts and drawing the large opening against the specified middle dies by sectional dies.
CONSTITUTION: A circular metal flat plate 1 is drawn by known concave and convex dies to form the circular truncated cone shape work 2 which has a collar 2a and is closed at its bottom 2b. Next, a small hole 3 is drilled at the bottom 2b and the collar 2a is trimmed to have an even width at its entire circumference. Thence the bottom 2b and collar 2a are flanged to form flange parts 4, 5 and at the same time to form a small opening 6 having an inside diameter equal to the outside diameter of the connecting pipe and a large opening 7. Two middle dies 8 of an outside diameter equal to the outside diameter of the connecting pipe are disposed by leaving a suitable spacing to the large opening side. A middle die 9 is disposed to the small opening 6 side as well, and sectional dies 10, 10 are pressed to the middle dies 8, 9 via guide blocks 12, 12 by a pressure 11 to draw the large opening 7 thereby forming the branch pipe parts 14, 14 branched by an intermediate butt part 13.
