Problems solved by technology

[0010] like Figures 8 to 10 As shown, the above-mentioned prior art mainly has the following problem: in the process of forming the inclined surface 4 and the groove 5 or 5' on the friction material 3 whose surface has been finely ground, the surface of the inclined surface 4 and the friction material 3 and the boundary line between the groove 5 or 5' and the surface of the friction material 3, the protrusions form burrs (burr) 22 that may have a negative impact on the initial performance of the friction material 3 although they are fine.
Therefore, even if the surface of the friction material 3 is ground smooth again by the fine grinding molars 19 of the fine grinding part 8, if the protrusions form the burrs 22 when the inclined surface 4 and the groove 5 or 5' are formed during processing, it will eventually reduce the The quality of the brake pads

[0078] The second embodiment will combine the attached Figures 18 to 20 to explain, and if Figure 4 As shown, in order to process and form the inclined groove 5' on the friction material 3 of the brake pad 1, some functions are added or modified on the basis of the first embodiment.

[0079] As described in the context of the first embodiment, from the supply part 30 to the coarse grinding part 32, the brake pad setting groove 58 of the transfer plate 60 is transferred in a state where the central axis X-X of the brake pad 1 is aligned. In addition, since the groove processing part 36 is provided with the groove molar 64 whose central axis is at right angles to the advancing direction of the machine table 56, the brake pad 1 transferred to the above groove processing part 36 needs to be made of the friction material 3 In the upward state, the central axis X-X moves at a certain angle with respect to the traveling direction of the machine table 56 .

[0087] The third embodiment will combine the attached Figures 21 to 24 to explain, and if Figure 23 and 24 As shown, on the basis of the first embodiment, components for removing the inner edge 106 of the friction material 3 of the brake pad 1 are added or deformed for this purpose.

[0088] Here, the "inner edge" of the friction material 3 refers to the friction material 3 that acts on the friction surface of the brake disc, and is formed according to the form of the brake disc. The edge of the central axis of the disk.

[0089] Such as Figure 23 and 24 , the inner edge 106 of the friction material 3 of the brake pad 1 is removed. The inner edge 106 is ground and removed in a straight line along the long axis of the brake pad 1 . Such as Figure 21 and 22 As shown, an inner edge removal processing portion 108 as a grinding removal inner edge 106 is provided between the supply portion 30 and the rough grinding portion 32 . The above-mentioned inside edge removal pr...

Abstract

The invention relates to a device for grinding brake block friction material, which comprises a first grinding part (34) which includes a supply part (30) for supplying brake block margin material, a rough grinding part (32) for grinding the surface of the friction material (3); a second grinding part (42) which includes a slot handling part (36) for forming slot (5 or 5') in the center of the friction material (3), a declining surface handling part (38) for forming declining surfaces (4) on the two sides of the friction material (3), and fine grinding part (3); a third grinding part (50) which comprises a cover part (44) for coating on the surface of the supporting board, a second fine grinding part (48) for handing the coated friction material.

Description

technical field [0001] The invention relates to a brake pad friction material grinding device, in particular to a device that can automatically complete a series of processes of grinding the surface of the brake pad friction material, machining inclined surfaces on both sides and forming grooves in the center. Brake pad friction material grinding device. Background technique [0002] Generally speaking, one side of a support plate for a brake pad of a disc brake is provided with a friction material. The processing process of the above friction material is as follows: on one side of the support plate made of steel plate, the powder raw material of the friction material is compressed to form a blank material of the friction material, and the surface is subjected to rough grinding and fine grinding. A series of grinding processes form inclined surfaces on both sides and straight or inclined grooves in the center. [0003] The prior art brake pad friction material grinding dev...
