摘要： PROBLEM TO BE SOLVED: To provide an elbow which can cause the small reduction of the thickness on the outer peripheral portion of a bent portion, and can suppress the generation of wrinkles on the inner peripheral side of the bent portion irrespective of the existence and nonexistence of a neck.
SOLUTION: In a cold bending method of the elbow having a target curvature of its axis, a mother pipe is inserted into a guide tube, and is successively or continuously extruded from the inserted side so as to reduce its diameter and so as to be bent. In the diameter reducing work, the wall thickness on the outer peripheral side at the bent portion is increased so as to be thicker than the wall thickness on the inner peripheral side, and the bending work is successively carried out. The diameter reducing work is carried out by means of an eccentric die, a pair of special shape rolls having different diameters, or by combining a half die and a roll. Thus, the wall thickness of the blank pipe on the outer peripheral side at the bent portion can be increased so as to be thicker than the wall thickness on the inner peripheral side at the bent portion.

摘要： PROBLEM TO BE SOLVED: To provide an elbow cold bending method having excellent forming efficiency and working yield by applying the optimum mandrel shape and excellent lubrication performance.
SOLUTION: In the steel tube cold working method for forming an elbow by pushing out a stock tube at normal temperature by a pusher while expanding the stock tube by a mandrel after continuously and annularly fitting the short stock tube as a work to the working mandrel, the mandrel is divided into a stock tube guide section, an expansion section, and a product guide section, and the circumferential length of the expansion section is larger than that of the product guide section. In addition, the sectional shape of the expansion section of the mandrel is elliptical, or substantially triangular elliptical, and the sectional shape at an outlet side end of the successive product guide section is circular.

摘要： PROBLEM TO BE SOLVED: To provide the product of a necked elbow in which thickness deviation is eliminated over the entire length, also the generation of wrinkles and local flattening in a bent portion are suppressed and excellent dimensional property and quality characteristics are secured.
SOLUTION: A method is for manufacturing the necked elbow by combining a necked part forming process for reducing the diameter by using a symmetrical die and a bent part forming process for performing bending until reaching a prescribed bending angle by holding the pipe stock with a bending arm and in this bent portion forming process, by thickening the wall thickness on the outer peripheral side of the pipe stock than the wall thickness on the inner peripheral side of the pipe stock and, simultaneously, providing a prescribed amount Os of offset on the bending arm, bending work is performed. It is preferable that the relationship between the amount Os (mm) of offset and the finished diameter d (mm) is Os/d=0.09-0.18.
