も発明した（特開昭６０−１６２５４１号）。(Prior Art) The inventor of the present application has made various improvements in the manufacturing method of this type of ring and edge ring, and has invented a method of press-forming from a metal tape (Japanese Patent Publication No. 1388/1988). He also invented a method for manufacturing edge rings that can be elastically deformed when worn depending on the application (Japanese Patent Application Laid-Open No. 162541/1983).

屈曲している。(Problems to be Solved by the Invention) According to the conventional manufacturing method described above, it is not possible to form the side wall into a vertical straight line and bend the upper and lower edges in one process using a set of molds. According to No.-162541,
Two molds are used, and a winding piece is used to bend the edge ring when fitting it.
従って側壁の直線部分を比較的幅広く設ける方法が解決

The above-mentioned conventional problems have been solved.

側壁による為、プレス中に変形するおそれはない。That is, in this invention, a short cylindrical ring is formed by cutting a metal tape having the width necessary for the edge ring into a predetermined length and welding both ends of the metal tape, and then inserting the short cylindrical ring into a female mold. The ring is set in a state where it supports the side wall, and then the male mold is lowered to curve the upper edge of the ring into an arcuate cross-section,
Manufacturability of the edge ring was improved by curving the lower edge to the same side as the upper edge. In paragraph vi, the upper and lower edges of the short cylindrical ring are curved outwardly or inwardly. This curvature is created by an annular groove with an arcuate cross section provided in the corresponding parts of the female and male molds. In this case, since the side wall of the ring is supported by an auxiliary mold (uI type) or the like, the side wall of the product remains vertical, so that the purpose can be achieved. Since the side wall support in the above is based on the female side wall having vertical walls, there is no risk of deformation during pressing.

Since the outer or inner walls of the ring are supported, the ring retains its original 1-shape as supplied without being deformed during processing.

After polishing the inner and outer walls of the welded part if necessary (if the welding condition is good, polishing is not necessarily necessary), fit it inside the first female mold 3 (Fig. 3), and then Lower edge to 2nd f
It comes into contact with the edge of the annular groove 5 of the i-type 4, which has an arcuate cross section. Then, when the male mold 6 is lowered as shown by the arrow 7, the upper edge of the ring is curved along the annular groove 8 with an arcuate cross section provided on the lower surface of the male mold 6. The lower edge of the ring is thus curved outwardly by the annular groove 5. In this way, the upper edge of the ring
At the same time that the curve 1#2a of a predetermined curvature is completed by the protrusion 10 of the female mold 9, a curved edge 2b is completed at the lower edge of the ring, and together with the linear side wall 2C, a predetermined edge ring 11 is completed.

法に仕上げることができる。In the embodiment described above, the upper and lower edges of the ring 2 are each curved inwardly. According to the method described above, the upper and lower edges of the ring 2 can be curved simultaneously in one step using the female mold and the male mold, and the side walls of the center can be molded to be relatively wide and without deformation. In this case, the first female mold 3 presses down the spring 12 as the male mold 6 descends, and the first female mold 3 moves to the direction indicated by the arrow.
3 (FIG. 4), the straightness of the side wall is maintained. Furthermore, as the male die 6 descends, the third female die 9 also presses down the spring 15 and descends as shown by the arrow 14, so that the upper curved edge 2a of the product edge ring 11 can be finished into a predetermined shape and size. can.

グの上下縁を外側へ湾曲する場合である。A short cylindrical ring 2 is formed by welding both ends of a tape material 1 made by cutting a stainless steel tape to a predetermined length,
If necessary, after polishing the inner wall of the welding part to make it flush, fit the inside of the lower edge to the outside of the first female mold 16, and attach the lower end to the side wall of the first female mold 16. It faces an annular groove 17 having an arcuate cross section. Next, move the male mold 18 to the arrow 1
When the male die 18 is lowered as shown in 9, the upper end of the ring 2 faces inside the annular groove 20 having an arcuate cross section (Fig. 6).When the male die 18 is further lowered, the upper end of the ring 2 is exposed. The edge forms a curved edge 2a with an annular groove 17, and the lower edge forms a curved edge 2b with an annular groove 20. In the above,
The curvature of the curved edge 2a is corrected by coming into contact with the protrusion 22 of the second female mold 21. The second female mold 21 is the male mold 18
As the curved edges 2a and 2b move downward, the spring 23 is pressed down and moves downward as shown by the arrow 24, so that the curved edge 2a is not excessively deformed, and the straight side wall 2C between the curved edges 2a and 2b is also not deformed and has the correct shape. is formed into. In the above embodiment, the upper and lower edges of the ring are curved outward.
