Abstract
PURPOSE: To perform bending easily and accurately by holding pipes by means of guide bodies having the cylindrical holding surfaces conforming to the outside circumferential surfaces thereof then bending the guide bodies.
CONSTITUTION: Convex and concave bending pads 12, 22 of prescribed curvature and guide bodies 13, 23 are opposedly mounted to the punch and die plate 11, 21 of the male, lower dies 1, 2 of a press. The guide bodies 13, 23 consist in supporting a multiplicity of superposed sheetlike bodies with backups 14, 24, and the top and bottom end edges thereof are supported linearly by means of leaf springs 15, 25. When pipes are fitted into the latter of the semicircular pipe holding surfaces 13a, 23a conforming to the outside diameters of the pipes and the male die 1 is lowered, the pipes are perfectly held by the surfaces 13a, 23a. When the male die 1 is lowered further, the guide bodies 13, 23 are shifted and moved successively vertically on the crooked surfaces of the pads 12, 22 against the lifting force of the springs 15, 25 and further knock-out pins 26, until finally they curve the pipes to the curvature of the crooked surfaces of the pads.
