Abstract
PURPOSE: To manufacture metal hose having no weld and also a specific shape at lower cost by the procedure in which a pipe is bent into approx. 180 degrees by using a bender with a specific function and then the bent pipe is inversed through approx. 180 degrees at the axial center of pipe to be bent by extrusion through a bending mold, both.
CONSTITUTION: One side of the pipe 17 is inserted into between the bending mold 18 and the clamp 19. The thickness E of the shortest portion of the pipe-pressing part of the clamp 19 and the thickness F of the shortest portion of the pipe-supporting part for the other side of the pipe 17, consisting of the roller 38 and the sliding plate 39, are made less than 2 times as much as the radius r of bend inside when the pipe 17 is bent into 180 degrees. Also, the clamp 19 is made detachable and also the force point G of the pressing metal 21 and the force point H of the supporting metal 28 are placed below the clamp 19 and the supporting mechanism whereby the tangent of at least one side bend tips of the hose can be made approx. 90 degree against the straight portion of the hose and also bend of the formula d ≈ 2r ≈ L-d can be obtained. (where d is the outside diameter of the pipe 17 and L is the distance of axial core between adjacent straight pipe portions)
