Abstract
A high speed bending method of a tube in which the proximal end on the front side of a tube P under a three-dimensionally bent state is set, as a machining reference point, at the origin of an orthogonal coordinate defined by X, Y and Z axes, the positions on each axis on the coordinate, and angles to two vertical planes (3) and an angle to a horizontal plane on the coordinate at each position are determined for a plurality of points including a bend from the proximal end to the distal end on the rear side of that tube, the bending path of the tube P is formed in a block-like die member as a path groove (1) of three-dimensional bend based onpositional data and angular data thus obtaining a three-dimensionally bending die G, proximal end of the straight tube P is set at the starting end of the path groove (1) in the bending die G, and a horizontal roller (4) is moved from the proximal end toward the distal end of the tube P while copying the path groove (1) and then the tube P is pushed into the path groove (1) and bent three-dimensionally.
