均一肉厚円筒部材の圧延製造方法に関するものである。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a method for manufacturing, by rolling, a "metal cylindrical member with uneven wall thickness" that has irregularities and steps on the inner and outer surfaces. The uneven wall thickness makes it possible to stably produce thin, non-uniform wall thick, large diameter cylindrical members made of particularly difficult-to-process metals with high precision and high yield without worrying about the occurrence of distortion. The present invention relates to a rolling manufacturing method for a cylindrical member.

形能が低い難加工性金属品等のリング圧延製品に対する
要望も増えてきている。The ring rolling method, which was developed mainly for the production of railway wheels, is now used for gears, piping flanges, steel tower flanges, and ropes because it allows mass production of highly reliable annular products with good productivity and high yields. It has come to be widely applied to the manufacture of various products such as sheep and manhole parts. As a result, ring-rolled products such as cylindrical products with thinner walls, large products with larger diameters and widths, products with complex special shapes with thick cross-sections, and even difficult-to-work metal products with low deformability are becoming more popular. Demand is also increasing.

つようになった。For example, titanium alloy has come to be used in various fields as a material with high specific strength, excellent heat resistance and corrosion resistance.
It is known to be particularly difficult to process among difficult-to-process metal materials such as high-alloy steel and superalloys, but recently, fields that require rolled cylindrical parts made of titanium alloys have become prominent. Ta.

製品化は不可能であった。However, products with relatively thick walls and simple cross-sectional shapes and products with small width dimensions can be manufactured using the ring rolling method even from difficult-to-process metal materials; If the cross-sectional shape is uneven, the larger the size, the more difficult it becomes to manufacture a product with the proper shape due to shape distortion due to uneven cooling.Especially when using difficult-to-work metals such as titanium alloys, ring rolling is the only method available. It was impossible to commercialize the product.

出すと言う手段を採用せざるを得なかった。Therefore, in order to produce rolled m-woven products of titanium alloy tubular bodies with irregular cross-sections having ring-shaped protrusions and grooves on the inner and outer surfaces as shown in Fig. 3, in addition to machining costs, It is manufactured by ring-rolling a cylindrical body with a cross-sectional shape as shown in Fig. 4 with extra thickness in consideration of shape distortion, and then machining it until it reaches the desired shape shown by the two-dot chain line. In addition, in the case of thin-walled products, it was necessary to adopt a method of cutting out the desired shape from a finish-rolled product into a simple rectangular shape as shown in FIG.

うにした点、°に特徴を有するものである。<Means for Solving the Problems> The present invention solves the above-mentioned problems that have been pointed out when manufacturing metal cylindrical products having a rolled structure, and produces thin-walled irregular cross-sections made of difficult-to-process metals. Even if it is a cylindrical body,
This ring rolling method was completed as a result of the research conducted by the present inventors, who made an earnest effort to provide a means for ring rolling with high precision and high yield without worrying about the occurrence of strain deformation. Alternatively, a cylindrical simple-walled raw material manufactured by ring forging method is housed in a cylindrical split mold, and then ring rolling is performed on this combination to create a metal cylindrical member with uneven wall thickness. It is characterized by the fact that it can be manufactured accurately and stably.
次いで、この発明の方法を、第３図に示される如き形状

円筒体を製造する場合の例に基づいて具体的に説明する
。Next, the method of the present invention will be specifically explained based on an example in which a thin cylindrical body made of a titanium alloy (Ti-6A I!-4V) having a shape as shown in FIG. 3 is manufactured.

３とされる。FIG. 1 is a schematic diagram illustrating the manufacturing process of the thin-walled cylindrical body. First, a round billet made of TTi-6A-4V alloy whose axial cross-sectional shape is shown in FIG. 1(a) is prepared. 1 is a material 2 with holes as shown in FIG. 1(b) by upsetting forging and punching after being heated to a hot working temperature.
[At this time, it was subsequently forged and stretched, as shown in Figure 1 (
A step of increasing the axial dimension as in c) may be added.]
Then, by rough rolling (rough ring rolling), the diameter is enlarged and the thickness is reduced as shown in FIG.

ャルロールをそれぞれ示している。Next, this cylindrical plain material 3 with a simple wall thickness is subjected to ring rolling again [Fig. 1 (e)), and the shape is properly adjusted to a certain extent within the range of a simple wall thickness shape that does not cause extreme shape distortion due to uneven cooling. It is formed into a simple thick rough material 4 which is formed into a wall thickness distribution shape. In addition, here, the reference numeral 5 indicates a king roll of a ring rolling mill, 6 indicates a mandrel, and 7 indicates an axial roll.
続いて、上述のようにして得られた単純肉厚荒地素材４

内面に刻設した円筒状分割型８に収容され、この分割型

１図（ｆ）〕。Next, the simple thick rough ground material 4 obtained as described above was prepared.
is housed in a cylindrical split mold 8 whose inner surface is engraved with a shape that is the same as the external shape of the target product or allows for some machining allowance, as shown in the schematic perspective view of FIG. Finishing ring rolling is performed while it is housed in the container 8 [FIG. 1(f)].
なお、第１図（ｆ）において符号１１は仕上げ圧延され

The reference numeral 9 in FIG. 2 indicates a split type hinge portion, and IO indicates a split type closure fixing pin.

軽減されてしまう。その上、多少の冷却ムラが生じたと
しても、被圧延素材の自由変形が分割型に拘束されてし
まっているので形状歪の生じる余地は殆んどない。In this way, the simple thick rough material 4 formed into a cylindrical shape is housed in the cylindrical split mold 8, and then this combination is subjected to ring rolling (the hot working temperature of the titanium alloy that is commonly used) is : 850 to 950°C is sufficient), and the rolled material is rolled into a cylindrical shape that is pressed against the inner surface of the split die 8 by the mandrel 6' and deforms to fit the engraved shape of the inner surface of the split die while reducing its thickness. The material is in close contact with the inner surface of the split mold and its temperature drops as one with the split mold, so even when molded into a thin wall with uneven thickness, uneven cooling is alleviated, leading to shape distortion and internal stress. The occurrence of residual distortion is reduced as much as possible. Furthermore, even if some cooling unevenness occurs, there is almost no room for shape distortion to occur because the free deformation of the rolled material is restricted by the split die.
従って、この方法によれば、チタン合金等の難加工金属

高い歩留（チタン合金製の薄肉大型円筒製品−第３図に
示す断面形状のもの−で、５０％以上の機械加工歩留を

品を量産することができる。Therefore, according to this method, even when manufacturing thin-walled cylindrical rolled products made of difficult-to-process metals such as titanium alloys and whose wall thickness cross-sectional shape changes complicatedly, the ring can be rolled to the final shape with almost no shape distortion. Is it possible to roll it?
At the very least, it has become possible to perform ring rolling to shapes with extremely small cutting allowances, and the yield is extremely high, which deviates from conventional wisdom (thin-walled large cylindrical products made of titanium alloy - those with the cross-sectional shape shown in Figure 3). , a machining yield of 50% or more can be ensured), making it possible to mass-produce products with good properties and dimensional accuracy.
ところで、これまで説明した工程例では第１図（ｄ）に

肉厚荒地素材４を経ることなく、単純肉厚荒地素材３を

の金属を対象としても何ら差し支えはない。By the way, in the process example explained so far, the ring rolling method is applied to the production of the simple thick rough material 3 shown in FIG. 1(d), but it goes without saying that the well-known ring forging method may also be applied. . Also, depending on the material and shape, the simple thick rough raw material 3 may be placed directly in the cylindrical split mold and subjected to finish ring rolling without passing through the intermediate simple thick rough raw material 4. However, there is no problem in targeting metals other than those that are difficult to process.
