In addition, since the SUS steel is used in which the C content is suppressed, workability is improved, and it is possible to integrally form by plastic working. In the martensitic stainless steel, the usual condition is that the C content is 0.15% or less.

できる。According to the method of manufacturing a cup-shaped part with a flanged shaft according to the present invention, since a dish-shaped depression is formed first, the lubricating coating rides on the depression well, and is formed in a subsequent plastic working step. Good lubricity is exhibited, and even a difficult-to-work material can be easily worked into a complex shape in a cold or warm state. Moreover,
First, since the small protrusions are formed to adjust the metal flow in the portion serving as the axis, the axis can be easily extended in the next step. And since extrusion molding is performed from both sides of the material, it is possible to form a shaft that protrudes from the cup at the same time as forming the cup. Furthermore, since the initially formed depression is dish-shaped, it plays a role of centering the material when forming the small projections and forming the shaft, and does not generate an uneven load. As a result, according to the manufacturing method of the present invention, a component having a complicated shape such as a cup with a flanged shaft can be manufactured by cold or warm plastic working while being a difficult-to-process material.

An embodiment of manufacturing a cup-shaped part with a flanged shaft as a motor hub for a hard disk using martensitic stainless steel equivalent to SUS410 will be described with reference to the drawings showing the steps.

「商品名ＤＳＲ１０ＦＳ」として販売されているので、
簡単に入手することができる。The steels A and B have almost the same component composition as the SUS410 steel, but suppress the C content, which deteriorates the workability, and have a better forging performance in cold state than the normal SUS410 steel. It has been improved. Also, the free-cutting component S
The shape is controlled so as to have a dispersed structure without forming a band, and the occurrence of cracks on the product side during forging is suppressed. The A steel and the B steel were obtained from Daido Steel Co., Ltd., the present applicant, as “trade name DSR10FA”,
Since it is sold as "Product name DSR10FS",
Can be easily obtained.

溝を刻設しないタイプの製品においてはなくてもよい。Next, a processing procedure using these steels A and B will be described with reference to FIG. First, a slag 1 having a predetermined length is cut from a round bar of steel A or steel B. Then, the slag 1 is placed on a parts former or a header and subjected to upsetting and punching to form a dish-shaped recess 3 and a center hole 5. The center hole 5 is formed because a thread groove is formed in the shaft portion in the final product, and may not be provided in a product having no thread groove.

Then, this is coated with an oxalate film and further immersed in an aqueous solution of MoS 2 to form a lubricating film of MoS 2 . Next, the slag 1 'with the lubricating film is put through a press machine and extruded forward. As a result, the metal flow at the center of the slag 1 'is adjusted in the direction of forming the axis.

A shaft 13 protruding from the cup 11 is also formed. Finally, sizing is performed, and a finish grinding process is performed to complete the part.

Despite using a considerable amount of material, the part
No abnormalities such as cracks in the money mold occurred even when about 10,000 pieces were manufactured. Further, the yield of the material was 80% or more.

は、一般のステンレス鋼を用いても構わない。On the other hand, when an attempt was made to manufacture the part using the A steel or the B steel without adjusting the metal flow during the above process, no shaft protruding from the cup could be formed. . In addition, when the above process was performed using SUS410 steel in which neither the suppression of C nor the shape control of the free-cutting component was performed, the mold life was shortened, and cracks were easily generated on the product side. In addition, the amount of shaft protrusion sometimes becomes insufficient. However, by performing the metal flow adjustment, the protrusion amount of the shaft could be increased as compared with the case where forging to the final shape was performed without performing this. Therefore, general stainless steel may be used as long as the amount of axial protrusion from the cup need not be so large.

Therefore, there is no doubt that various mechanical properties such as fatigue strength, corrosion resistance, and wear resistance are improved as compared with conventional products manufactured by cutting.

I do. As a result, the manufacturing cost of a SUS steel cup-shaped component with a flanged shaft was significantly reduced.

適用も十分な効果を発揮するからである。Although the embodiment has been described above, the present invention is not limited to this embodiment, and it goes without saying that the present invention can be implemented in various modes without departing from the scope of the invention. For example, the manufacturing method of the present invention is not limited to steel materials equivalent to SUS410, but may be used to manufacture a cup-shaped part with a flanged shaft using not only martensitic stainless steel, but also austenitic stainless steel, tool steel or superalloy. It goes without saying that it can be applied. In addition, it goes without saying that the present invention can be applied to a cup-shaped part with a flanged shaft other than a hard disk motor hub and a method of manufacturing the same. In addition, in carrying out the method of the present invention, warm working may be employed instead of cold working. For a large product that is subjected to hot working, the method of the present invention need not be specifically applied, but this is not excluded. This is because, by applying the present invention, the burden on the mold can be reduced, so that the application of the present invention to hot working also exerts a sufficient effect.
