Abstract

PURPOSE:To improve the shape quality of the pipe of a product by forming a tapered drawing part at both ends in the line direction of a die and arranging a pair of manipulators in opposition to a forging press. CONSTITUTION:A forging machine 8 is installed on a foundation and the tapered drawing parts 2, 3 of both ends in a line direction are respectively formed on a pair of upper and lower dies 4, 5. Moreover forward manipulator 10a and backward manipulator 10b are arranged in opposition on a guide rail 9. The pipe blank 28 fitted into a core rod 31 is moved by holding it by the tongue levers 23, 24 of the manipulator 10b, set between the dies 4, 5 and the part from the tip to the center of the blank 28 is forged by the drawing parts 2, 2. Then with giving a tension to the blank 28, the part from the center to the rear end is forged by the drawing parts 3, 3. Since uniform forming is executed up to the terminal part of the blank 28, the shape quality of the product pipe is thus improved.
