Abstract
PURPOSE: To form an undeformed bead, by putting a press frame upon the flange fully surrounding a water tank, when the bead is formed so as to fully surround the wall of the metal made water tank, using an inner roll possessing a ring type cavity and an outer roll possessing the ring type projection.
CONSTITUTION: The metal made water tank 3 is placed on the smooth flat table 7 of the bead forming apparatus, and the circumferential wall of the water tank 3 is placed between the inner roll 8 possessing the ring type cavity 8a and the outer roll 9 possessing the ring type projection 9a. Hereupon, the press frame 18, possessing inside dimension equal to the outside dimension of the water tank 3, is attached to the circumference of the water tank 3 so as to contact tightly with the flange 19 of the water tank 3. Under this condition, the oil pressure is given to the cylinder 16, and the outer roll 9 together with the auxiliary roll 20 are moved along the circumference of the wall of the water tank 3 so as to thrust the wall against the inner roll 8 which is then rotated. The water tank 3 is pressed by the press frame 18 and causes the deformation so that the bead is formed without deforming the shape of the water tank 3.
