Abstract

PURPOSE: To improve strength of a flange part and seal effect of a joint face by forming a projecting part in the joint face part with a concave die and a punch having the wide width than the concave part of the concave die.
CONSTITUTION: Opposite to the flange part 3 of a box shaped body made of a metal sheet, the forming part upper face 13 of the lower molding die 10 consisting of a holder 11 and a forming part 12 is faced. On the face 13, a groove 14 in a specified depth surrounding the forming part 12 is provided, and the side walls 15, 15' of the groove 14 are provided with vertical to the even bottom 16. On the other hand, above the forming groove 14, a punch 20 for pressing is provided, and the width W of its forming part 21 is set larger than the width W1 of the forming groove 14. By pressing the punch 20, a projected part 6 is formed so as to surround the lower face of the flange part. Since the width of the punch is larger, the organization is made pressure tight. This flange part 3 face is tightened by a bolt 41 with the opposite side flange part 31 mounting packing material 40 between them. The projecting part 6 bites in the packing 40 and the seal becomes positive.
