The present invention relates to a disc brake pad used for industrial machines and the like and its back metal.

が、発生する熱エネルギーが大きい場合には、接着剤は
その熱により劣化し、接着力を低下させる。Disc brake pads consist of a friction material that contacts a rotating disc and converts kinetic energy into heat energy, and a back metal that is pushed by a piston of a brake caliper. It is firmly bonded with an adhesive. However, when the generated thermal energy is large, the adhesive is deteriorated by the heat and the adhesive strength is reduced.

によって保ちうる構造になっている。From this experience, the backing metal and the friction material are adhered on a flat surface, and a hole is made in a part of the backing metal, and the friction material goes around there. And the structure is such that the shearing force applied to the friction material can be maintained by the unevenness.

悪影響を与えるものとなる。Most of the holes of the back metal are punched holes because of the punching process of a thick steel plate in manufacturing, and a step of integrating the friction material into the holes by heat and pressure molding is taken. Is. Therefore, if the friction material does not sufficiently go around the hole formed in the back metal, that part becomes sparse, and if water is applied to the brake, the back side of the back metal, that is, the surface opposite to the friction material side surface, becomes this sparse part. It becomes easier for water to enter. The water that has penetrated causes the back metal to rust and adversely affects the adhesion.

In Japanese Patent Laid-Open No. 43136/1993, instead of a through hole, a protrusion is provided on the front side, that is, the friction material side by a half shear from the back side, and a part of the backing metal is also protruded on the back side, that is, the side opposite to the friction material by the half shear. Along with the introduction of the product and the one in which a part of the friction material side is carved, a plan to make a larger recess around the portion of the through hole and to embed the through part by the force is disclosed. Further, Japanese Utility Model Application Laid-Open No. 5-83483 discloses that a part of the back metal is pressed to form a recess and at the same time, a part plastically deformed by the pressure is projected to the friction material side.

く、疎な部分が生じやすい。As described above, there is a means for forming irregularities on the adhesive interface with the friction material without providing through holes in the back metal, but the one using half shear has a convex portion on the back side. In the case of, when the brake is used, interference occurs with the piston that is operated by pressure, and in the case of a convex portion on the front side, if it projects too much, the limit of use of the friction material, that is, the wear limit will be reduced, and if the amount of projection is small, The effect on shear forces is reduced. Further, in the case where a part of the back metal is pushed in and the circumference is projected in an annular shape, the friction material is less likely to enter the inside thereof, and a sparse portion is likely to occur.

It will be an obstacle in the work such as stacking the two, and it will affect the storage in the case. As another means, there is a means of partially cutting out the friction material side of the back metal by cutting, but in the step of cutting the back metal, positioning and removal at the time of processing one by one are complicated, and the cost becomes high.

ｍ以上あればさらに好ましい。According to the present invention, in a back metal of a disc brake pad, there is a recess on the surface where the back metal contacts the friction material, and there is no protrusion on the corresponding back surface.
The recess has an inclined portion that intrudes with an inclination of 10 to 50 degrees with respect to the friction material side surface of the back metal, and a raised portion that rises almost vertically from the deepest portion to the back metal, and this raised portion acts on the disc brake. It has a role to counter the shear force. If the height of the part that rises almost vertically to the back metal is set so that it does not exceed the wear limit of the friction material from the surface of the back metal on the friction material side, it will not be affected by the wear of the friction material. ,preferable. Further, if the height of the portion rising perpendicularly to the back metal to counter the shearing force is 1/4 or more of the thickness of the back metal as viewed from the deepest part, the effect can be sufficiently obtained. 1.5m
It is more preferable if it is m or more.

分耐えることができる。Furthermore, it is preferable that the vertically rising portions are not protruded from the surface of the back metal because the back metals can be easily overlapped at the time of manufacturing the pad. In this case, it is achieved by once forming a through hole in the back metal, and then making the inclination as described above and at the same time embedding the through hole. That is, the amount of plastic deformation that is extruded and raised by the inclined portion corresponds to the volume of the through hole that was opened previously. And the disc brake pad made using the back metal produced in this way is
Since there is no through hole in the back metal, it is possible to prevent water from entering from the back side of the pad and to sufficiently withstand the shearing force generated when the brake is used.

い。Particularly, the angle at which a part of the backing metal is inclined is caused by the angle at which the friction material can wrap around in a later step. If the angle is made steep, the material cannot wrap around the inclined portion during heat-press molding of the friction material. , 50 degrees or less is appropriate. On the other hand, if the angle is too small, the pressing pressure required to raise the vertical portion is large, which is uneconomical. However, the smaller the angle, the better the wraparound of the friction material during heat molding, and the greater the effect of contributing to the shearing force of the finished pad. Therefore, the angle is compatible with both economical efficiency and effect, but is set to 10 degrees or more. It is preferable to select an angle of 15 to 40 degrees.

の直径程度の幅があれば十分である。The surface of the vertical portion rising from the deepest portion is to oppose the shearing force applied to the disk pad, so that the direction of the inclined portion is preferably parallel to the longitudinal direction of the back metal. When it is piled up in a cylindrical shape, it may be oriented in all directions around it. But,
The existence of the part facing in the longitudinal direction is essential,
It is natural for its purpose. The width of the inclined portion is also preferably wide, but if a shearing force similar to that of a backing metal having a through hole that is currently used is required, a width about the diameter of the through hole is sufficient.

Fine blanking is a metal working method used to increase the plastic deformability of a material by generating hydrostatic pressure by applying three forces to the material: shear pressure, plate pressing pressure, and back pressure in press processing of the back metal. Depending on the mold, the above shape can be built during the pressing operation.

The back metal 1 is made by punching out a mild steel plate, and the friction material side of the back metal 1 is treated with the present invention at two places. There is a protruding portion 2 raised by an inclined portion 3 without protruding to the back surface of the back metal, and the boundary between 2 and 3 is substantially perpendicular to the back metal. This vertical portion is oriented in the direction of the shearing force of the brake. Generally, two disc pads are used facing each other for one brake. Therefore, as shown in FIG. 1, the embodiment of the present invention has a symmetrical position in the longitudinal direction of the back metal. It is better to use an even number.

出部分はない。FIG. 2 is an application of FIG. 1 in which the slanted portions 3 face each other with the raised portion 4 therebetween. Although the vertical portion of the raised portion 4 has an arc shape, such a shape is also preferable because it has sufficient proof stress against shearing force and is effective against shearing force deviated from the longitudinal direction of the backing metal. FIG. 2B is a cross section taken along a line connecting the protrusions in FIG. The front side (friction material side) 7 is processed, but the back side (opposite side of the friction material) 8 has no protruding portion due to processing.

ｍｍより高く盛り上げないように調整すればよい。FIG. 3 is a conceptual diagram showing the features of the present invention. The raised portions 2 and 4 can be formed by forming the angles A and A'of the inclined portion 3 in (a) and (b). This is due to the plastic deformation of mild steel, so that pressure is applied to parts where it is needed, such as pressing up unnecessary parts.
There is a device such as a metal mold that adjusts the bulge of plastic deformation to prevent deformation of the entire shape, but fine blanking can be used. In particular, it was mentioned earlier that the convex portion of the backing metal on the friction surface side affects the life of the friction material when it is raised higher.However, as shown in (a), the shape of the raised portion is held down to exceed the wear limit. If it is not included, it is preferable because it does not affect the life of the friction material. Generally, the wear limit is 1 to
Most of them are about 2 mm, so 1-2 from the back metal surface
It may be adjusted so that it does not rise higher than mm.

分布が均一となり好ましい。FIG. 4 shows a further embodiment of the present invention. In this method, first, a through hole 5 is formed at a position corresponding to the raised portion of the backing metal 1 (a), and then the inclined portion 3 is provided around the through hole 5.
Simultaneously with the production of (1), the extruded portion is guided to the side of the through hole (b), and the inclined portion 3 is further pushed to a predetermined size (c), whereby the raised portion 4 is formed in a protruding shape. At this time, since the remainder obtained by subtracting the volume of the through hole 5 opened first from the pushing volume of the inclined portion becomes the raised protrusion 4, the height of the protrusion 4 is the volume of the through hole 5 and the dimension of the inclined portion 3. It is possible to make a state in which the protrusion 4 does not appear on the surface of the back metal 1 as a result. If the protrusion is almost equal to the back metal surface,
When the friction material is heat-molded, the distribution of the molding pressure applied to the friction material is uniform, which is preferable.
