Abstract
PURPOSE: To prevent a formed pipe from generating corrugated and elliptial shapes of the border between bent part and straight part, and to form the titled product of good quality in one body by a difference of bent angle at the pipe shaped part of the upper and lower dies which forms an elbow with straight pipe.
CONSTITUTION: A pipe material 10 is placed on a lower die B, and an upper die A is lowered by a press upon it to form an elbow 10a with straight pipe. As the pipe shaped parts 1 are provided to the upper and lower dies A, B, a sideward expanding of the pipe material 10 is prevented at the time of its bending. And as the angle θ2 of the lower die B is smaller than the angle θ1 of the upper die A by 3W7°, some allowance 11 between underside of the elbow 10a with a straight pipe and a pipe shaped part of the lower die B does not restrict the distortion of underside of the elbow 10a with straight pipe thus enabling it to prevent from generating elliptical shape at the section of the border of the straight pipe and further the corrugated shape of upside of the elbow.
