Abstract
PURPOSE:To improve accuracy of finishing and prevent occurrence of protruding and creases in bent parts by making at least one of two dies freely formable and making the contact area between the die at the time of initial extrusion and a workpiece as large as possible. CONSTITUTION:A workpiece 3 in which a part to be worked is heated by a burner is placed on the die 12 of a base stand 1, and positioned by a guide wall 13 and a gauge 17. A pressing stand 2 provided with freely formable pressing parts 23, 23' moves down and bending is effected. The pressing parts 23, 23' of this worked product bent in this way are always in close contact. Accordingly, accuracy of finishing is excellent and entirely free from protruding and creases in bent parts.
