〈産業上の利用分野〉
本発明は、回転鍛造圧縮加工により部材を製造する回転
鍛造機に関するものである０〈従来技術〉
従来、例えば一般に突き合わせフランジは、同じ圧力等
級、同じサイズでも突き合わせるパイプの肉厚によって
各々内径寸法が変わるものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a rotary forging machine for manufacturing a member by rotary forging compression processing. <Prior Art> Conventionally, for example, butt flanges generally have the same pressure class. Even if the pipes are of the same size, the inner diameter varies depending on the wall thickness of the pipes that are butted against each other.
しかして前述のような突き合せフランジ等の製品の歩留
を向上させるには各々の型の回転鍛造機を所持すること
が好ましいが、これでは型コストの増大を招く。In order to improve the yield of products such as butt flanges as described above, it is preferable to have a rotary forging machine for each type, but this results in an increase in mold cost.

うるようにしていた。Therefore, conventionally, when forging the same type of product with only the inner diameter dimension differing in a rotary forging machine in which the mold rotates, 81
As shown in FIG. 2, the lower mold A was divided into an inner mold 1 and an outer mold 2, so that the inner mold 1 could be replaced according to the inner diameter dimension of the product B.

型１の取替時のボルト着脱に長時間を要し、作業性が悪
いとの欠点があった。However, in this conventional example, since both the inner and outer molds 1 and 2 are fixed to the rotary table 3 with bolts (4.4), it takes a long time to attach and remove the bolts when replacing the inner mold 1. It had the disadvantage of being of poor quality.

、やは９作業手間であるとの欠点があった。Next, Fig. 2 shows what is called a lap splitter.As shown in the figure, the outer mold 2 is fixed on the rotary table 3 with fixing bolts 4, and the outer mold 2 has a concave locking part. 6, a substantially convex engaging portion 7 that engages with the engaging portion 6 is formed on the inner mold 1, and the inner mold 1 is mounted on the rotary table 3. In the example, since the inner mold 1 is not fixed to the rotary table 6, the driving force for rotating the lower mold cannot be transmitted to the inner mold 1. For example, the rotary table 3 and the inner mold 1
It is necessary to create a separate groove for driving force transmission, such as providing a radial fit (clutch), and in order to replace the inner mold 1, the outer mold 2 must be removed. , and had the disadvantage of requiring 9 hours of work.
