| PROBLEM TO BE SOLVED: To improve internal pressure fatigue strength by imparting pressing force in the boss part shaft direction to a prepared hole formed in a boss part, and cutting off a microscopic defect part generated in a prepared hole part after generating compressive residual stress on the periphery of a main pipe rail flowing passage opening end part of a branch hole. SOLUTION: A bottomed prepared hole 3a is cut and formed in a boss part 2 of a main pipe rail 1a, and pressing force is imparted to an inside bottom part of the boss part 2 by a punch 4 having a diameter slightly smaller than an inside diameter of the prepared hole 3a. An inner peripheral surface of a main pipe rail flowing passage 1a-1 is slightly projected to generate a plastic and elastically deformable part, and after removing the pressing force, compressive residual stress is generated. Next, the prepared hole 3a is cut in a large diameter hole by a drill having a diameter larger than an inside diameter of the prepared hole 3a so that a microscopic defect part is cut off to form a branch hole 5a forming a circular outward opening peripheral surface leading to the flowing passage 1a-1 as a pressure receiving surface 6a, and an outer screw 7 is worked on a boss part outer peripheral surface to thereby improve internal pressure fatigue strength of a branch pipe connecting part to improve durability as well as to eliminate fluid leakage. | ||||||

| PROBLEM TO BE SOLVED: To lighten a product and to improve the yield and the productivity by ironing a hollow block with cold-forging and forming a spline to a corresponding part with the cold-forging while utilizing the work hardening. SOLUTION: A Bonderite treatment is applied to the hollow blank and forming load is given with a hydraulic press and the hollow blank is extruded forward with the cold-forging. Successively, after executing a softening-annealing and the Bonderite treatment, the forming load is given with the hydraulic press. Further, the forming load is given with hydraulic press after executing the Bonderite treatment without softening-annealing, and the spline formation is executed on a prescribed outer periphery to obtain a long spline shaft. Since the formation with the hollow blank is executed, the product can be lightened, and high frequency induction hardening after the softening-annealing and the forming before forming the spline is unnecessitated, and the shortening of the precess and the reducing of the cast are obtd.
