摘要： PROBLEM TO BE SOLVED: To provide a forging method capable of suppressing bends of a work caused when a round bar is manufactured by free forging including high speed forging.
SOLUTION: In the forging method for manufacturing the round bar by repeating reduction with the anvil to the work A from the direction perpendicular to its axis and movement in the axial direction, when performing a forging pass by which the cross-sectional shape of the work after reduction is made into a circle, the forging is performed by using a round groove anvil which satisfies the inequlity {(the radius of the finished cross section of the work) > (the radius of curvature of the groove bottom part of the round groove anvil)}. It is preferable that the circularity (the maximum diameter - the minimum diameter) of the finished cross section of the work is small and the cross section becomes a circle or a shape near the circle when the difference between the radius of the finished cross section of the work and the radius of curvature of the round groove anvil is

SOLUTION: A mandrel 1 is used for a manufacturing method of a tube by hot extrusion by which a heated material 4 to be worked is made into a metallic tube by forward extruding the material 4 to be worked from the ring- like clearances formed among a container 3 inside which the heated material 4 to be worked is charged, a die 2 in front of the container 3 and the mandrel 1 penetrating through the material 4 to be worked, the clearances being formed when the material 4 is inserted into the die 2. The outside diameter of the mandrel is gradually increased toward the side of the rear end in the part behind a part with which an upsetted material 4 to be worked is brought into contact when upsetting so as to satisfy d2≤d1-96/L so that the diameter of the tube extruded in front of the mandrel when the extrusion is completed is equalized in the axial direction. Where, d2 is the outside diameter of the mandrel situated at the tip of the extrusion of the material to be worked, d1 is the outside diameter of the mandrel situated at the rear end of the extrusion of the material to be worked and L is the length of the material 4 to be worked.
