品の信頼性を保つためには、格段の注意を要する。[Detailed Description of the Invention] Conventionally, in order to manufacture a metal bat, a light alloy pipe is usually drawn into a tapered shape, and a camp-shaped grip of a slightly larger diameter, which is manufactured separately, is welded to the tip of the pipe. Ta. Therefore, manufacturing is time consuming and costly, and great care is required to maintain product reliability.
このような欠点を除去するため、テーパ状に絞った端部

とも考えられるが、絞り加工に伴う加工硬化のため、亀
裂が入ることが多く、実際的ではない。In order to eliminate such defects, it is possible to form a grip by expanding the diameter with a tapered end t or an expander, but cracks may occur due to work hardening that accompanies the drawing process. There are many cases and it is not practical.

次縮径(1a)させる。As shown in Figure 1, a light alloy pipe (1) with dimensions corresponding to the thickness of the bat to be obtained is hung on a rotary swaging machine. By moving the pair of rotating dies (2) and (3) and vigorously hitting the die, key points of the nozzle (1) are gradually reduced in diameter (1a).
なおこの縮径部(1a)の外径は、第6図に示″を最終
製品におけるグリップ(6)の径とほぼ等しい。The outer diameter of this reduced diameter portion (1a) is approximately equal to the diameter of the grip (6) in the final product as shown in FIG.

As shown in Fig. 6, the grip υ part (
A product is obtained in which a grip (6) of a desired diameter that expands in a trumpet shape is connected to the end of 1b).
グリップ(6)の端面開口部に、適宜の基体を嵌着する
ことにより、金属製バットが完成される。A metal bat is completed by fitting a suitable base into the end opening of the grip (6).
