９−２８２９８号公報参照）。DETAILED DESCRIPTION OF THE INVENTION With an annular member having a desired shape inserted into a key point of a material tube, the key point of the material tube is bulged to bulge, thereby making the annular member into a material. Methods for manufacturing cylindrical shafts with protrusions such as camshafts that are integrally coupled with pipes are known (for example, Japanese Patent Publication No. 46-7644, Japanese Patent Publication No. 46-7644).

それがある。In this case, if the annular member is not firmly connected to the material tube without any gaps, the annular member may rotate relative to the material tube due to external forces acting on the annular member in the centripetal or circumferential direction during use. , or may shift in the radial direction.

びにより、破損することがある。However, the fluid pressure for bulging increases rapidly from the moment the material tube comes into close contact with the inner peripheral surface of the annular member, so it takes a lot of effort to firmly connect the annular member to the material tube without any gaps. This requires a large amount of fluid pressure, which makes the equipment large and takes time to process.The annular member, which is often manufactured by sintering, is prone to breakage due to excessive internal pressure and elongation. be.

しく低い圧°力てバルジ加工しつるにも拘らず、環状部
材が素材管に対して。The present invention allows the material tube to be completely brought into close contact with the inner surface of the annular member during bulge processing, leaving a slight gap between the two, and is therefore significantly more effective than in the case of conventional methods. Even though the bulge is processed under low pressure, the annular member remains against the material tube.

ないようにした突起付円筒軸の製造方法を提供しようと
するものである。It is an object of the present invention to provide a method for manufacturing a cylindrical shaft with projections that does not easily move in either the circumferential direction or the radial direction.
以下、図面に基いて５１本発明の詳細な説明する。Hereinafter, the present invention will be described in detail based on the drawings.

受孔（１渇が、交差状に連設されている。In Figures 1 and 2, (1) is an old molding die with half molds facing each other, and a material tube (2) on the opposite surface.
A semicircular groove (01) is provided in which the semicircular groove (01) is properly fitted, and an annular member (3) as a tightening material loosely fitted into the material tube (2) is provided at key points of the semicircular groove (01). The semi-circular receiving holes (1 hole) into which the holes can be properly fitted are arranged in a row in a criss-cross pattern.

The inner hole (31) is formed into an oval shape by making one side of the circular part corresponding to most of the outer peripheral surface of the material tube (2) slightly smaller in diameter and protruding (3) in the radial direction. At the center of the inner side of this protrusion (32), there is an axial receiving protrusion (32) whose inner end faces inward so as to be close to the outer circumferential surface of the material tube (2).

に。With the material tube (2) into which the five annular member (3) is loosely fitted into the mold (1), pressurized fluid is introduced into the material tube (2) by an appropriate known means. , material tube (2)
is slightly deformed and comes into contact with the inner end surface of the receiving protrusion (33) and the surface of the inner hole (31) opposite thereto, and as shown in FIG. 3, the inner end of the receiving protrusion (3el) Both sides are slightly bitten, and both sides of the receiving protrusion (33) and the material tube (2
) with a slight gap (4) remaining between the outer peripheral surface.
圧力流体による加圧を中止する。Stop pressurizing with pressure fluid.
このようにすれは、圧力流体により素材管（２）が変形
させられている間に、バルジ加工が終了することとなり
、従来のように、素材管が環状部材の全内周面に接触し
てから、さらに高圧力が負荷されるごとはない。In this way, the bulging process ends while the material tube (2) is being deformed by the pressure fluid, and unlike the conventional method, the material tube comes into contact with the entire inner peripheral surface of the annular member. Since then, there is no possibility that higher pressure will be applied.

なものとすることができるとともに環状部材が、バルジ

い。Therefore, the required bulge addition can be achieved using relatively low pressure fluid.
Therefore, the processing apparatus can be made into a wooden type and simple, and the annular member will not be damaged due to excessive pressure and elongation accompanying bulge processing.
しかして、素材管（２）の外周面の大部分は、環状部材
（３）の内面の受止突条（３３）の内面に当接するとと
もに、その両側に喰込み状態となっているので。Therefore, most of the outer peripheral surface of the material tube (2) is in contact with the inner surface of the receiving protrusion (33) on the inner surface of the annular member (3), and is bitten into both sides thereof.
環状部材（３）が、素材管（２）に対して回転すること
はない。The annular member (3) does not rotate relative to the material tube (2).
また、環状部材（３）をもってカム等としたとき。Also, when the annular member (3) is used as a cam, etc.

。Even if a large centripetal load or repeated load acts on that high place, the load will be transferred through the receiving ridge (33).
Since it is received by the material tube (2), there is no fear that the annular member (3) will shift in the radial direction with respect to the material tube (2).
