Description of the Related Art In a product such as an oil seal or a gasket in which rubber is formed on a metal, an adhesive is coated on a surface of a metal ring as a metal part in order to bond the metal and the rubber. As a coating method, an immersion method (a metal ring is immersed in an adhesive liquid layer, and then dried and baked) is frequently used in view of the properties of the adhesive film and the working efficiency, but FIG. 4 (A) When a plurality of metal rings a are immersed in the adhesive liquid b at the same time as shown in FIG. 3B, the metal rings a aggregate with the adhesive liquid b as shown in FIG. Therefore, when drying and sintering are performed in this state, the metal rings a are firmly fixed to each other via the adhesive b ′ as shown in FIG. That is, the ring a is formed in a state where two rings are stuck together). This adhesion failure often occurs particularly when the metal ring a is thin, flat, and small.

The metal rings a are fixed to each other by the surface tension of the adhesive liquid b between the rings a (see FIG. 4B), and the metal rings a are fixed via the adhesive b ′ solidified in the subsequent drying and sintering process. This means that they adhere to each other (see FIG. 4C).

である。Therefore, a "separating step" of separating the metal ring a by applying an impact to the metal ring a overlapping each other after the metal ring a is lifted from the adhesive liquid b is added.
For this reason, extra man-hours are required. Also, in this “separating step”, since the magnitude of the impact that can be given is limited (the magnitude of the applied impact must not be so large as to deform the metal ring a), it is thin and flat and small in size. In reality, a sufficient effect cannot be obtained with the metal ring a.

Is not to provide the surface roughness 1c by directly processing the metal ring 1, but to use a press die 13,
The surface roughness is transferred to the metal ring 1 by providing a certain surface roughness 15 at a portion 14a corresponding to the surface roughness 5 formed on the surface of the metal ring 1 of 14. However, a sufficient effect can be obtained. Although the level of the surface roughness 15 of the roughness adding portion 14a of the lower mold 14 required to obtain the surface roughness 5 of the lower mold 14 varies depending on the processing conditions, the mold, the material of the rolled steel, and the like, it cannot be said unconditionally. In a general cold-rolled steel sheet, the pressing surface pressure is about 60 kgf / mm 2 and the transfer rate of the mold roughness is 50 to 60%.
Therefore, the level of the surface roughness 15 formed on the roughness adding portion 14a of the lower mold 14 is 40 to 120 μm (40 μm to 1 μm).
20 μm or less). The transfer rate of the surface roughness has a correlation with the press surface pressure, the material hardness, and the like.

There are many machining methods such as electric discharge machining, grinding stone polishing or shot blasting. However, if a specific part of the mold 14 as in the present embodiment is particularly complicated, the electric discharge machining is performed. Processing is useful. In general, when machining with an NC electric discharge machine, the roughness is controlled by the discharge time, the distance between the electrode and the work, the voltage, the swing of the electrode, and the like. Once decided, the above conditions are naturally determined.

るものである（図３参照）。As described above, the principle of preventing sticking by adding the surface roughness 5 to the metal ring 1 is to reduce the adhesive bonding area between the metal rings 1 after drying and sintering, thereby reducing the bonding area. It prevents sticking by reducing the proportional adhesive force (see FIG. 3).

In addition, it is possible to easily form the surface roughness 5 on a specific portion 1 a of the metal ring 1, improve the processing accuracy of the surface roughness 5, improve the maintainability of the mold 14, and process It is possible to reduce costs and man-hours.

１への粗さ転写効率を向上させることができる。When the surface roughness is transferred from the mold 14 to the metal ring 1 in this manner, depending on the shape of the mold 14 and the magnitude of the pressing force at the time of processing, the shortage of the contact surface pressure at the time of processing is required. There is an item whose surface roughness is not sufficiently transferred from the mold 14 to the metal ring 1. As a problem of the escape allowance of the material (metal material) of the metal ring 1, the roughness adding portion 14 a of the mold 14 and the metal ring 1 In the case of an item having a large contact area, unevenness may occur in the transferred surface roughness. For example, in the metal ring 1 in the above embodiment, the contact surface 1a has a radial variation,
There is a concern that the transfer rate is high at the end in the radial direction and the transfer rate is low at the center in the radial direction. It is preferable to provide a concave portion (not shown) such as a groove having a depth greater than the surface roughness 15 in addition to the roughness adding portion 14a. Surface roughness 1
5 and a concave portion such as a groove, it is possible to increase the contact surface pressure at the time of processing because the contact area is reduced, and it is possible to secure a clearance for the material of the metal ring 1. Thereby, the efficiency of the roughness transfer from the mold 14 to the metal ring 1 can be improved.
