〔産業上の利用分野〕
この発明は、摩擦材が有機質の材料によって形成される
ディスクブレーキパッドを、安価に能率良く生産するた
めの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a manufacturing method for efficiently producing a disc brake pad whose friction material is made of an organic material at low cost.
アスベスト系パッドのように、摩擦材の殆んどが有機質

摩擦係数が変化する(いわゆるフェード現象を起こす)
ので、その防止策を必要とする。Disc brake pads in which most of the friction material is made of organic materials, such as asbestos-based pads, or disc brake pads in which part of the friction material includes organic materials, such as semi-metallic pads, are The frictional heat generated during the process generates gas, which changes the coefficient of friction with the disc (causing the so-called fade phenomenon).
Therefore, preventive measures are required.

向のスリットを設けて、ディスクとの摺接によりディス
ク回入側で先に発生してディスク回収側に向かうガスの
流れをこのスリットで遮断する方法の2つがある。Conventionally used methods to prevent this fade include scorch treatment, in which the completed pad is heat-treated to release gas in advance, and slits in the radial direction of the disc are provided in the friction material's sliding contact surface with the disc. There are two methods: one uses the slit to block the flow of gas that is generated first on the disk input side and heads toward the disk recovery side by sliding contact.
〔発明が解決しようとする間1題点〕
しかLながら、上記の従来法は、いずれも加工タクトが
長く、作業の連続的な自動化も難しいことから、加工コ
スト、特に直接加工費が非常に高くつく欠点がある。[One problem that the invention is still trying to solve] However, all of the above conventional methods have a long processing takt time and it is difficult to continuously automate the work, so the processing cost, especially the direct processing cost, is very high. It has the disadvantage of being expensive.
また、前者の方法は、スコーチ処理時に臭気、タール等

の方法は、スリットの加工を切削や研削によって行りて
いるため、加工時に発生する粉塵の回、収設備を必要と
する欠点もある。In addition, the former method generates odor, tar, etc. during scorch treatment, and requires equipment to collect them.On the other hand, in the latter method, the slits are processed by cutting or grinding, which generates odor and tar during processing. Another drawback is that it requires equipment to collect and collect the dust.
この発明は、これ等の欠点を解消して、有機質の材料を
含むディスクブレーキパッドを、安価に、しかも、量産
性良く製造し得るようにすることを目的としている。The object of the present invention is to eliminate these drawbacks and to make it possible to manufacture disc brake pads containing organic materials at low cost and with good mass productivity.

A press mold 4 is pressed against the disk sliding surface 3 of the friction material 2 containing an organic material that adheres to one surface, and a protrusion 5 having a height of no more than n formed on the front surface of the mold 4 allows A feature is that grooves 6, which are impressions of protrusions, are formed on the disk sliding surface 3.
溝6は、裏板1と摩擦材2とを予め接着しておき、それ

る。The grooves 6 can be formed by bonding the back plate 1 and the friction material 2 in advance, placing them on the stand 7 of the press as shown in the figure, and machining them at room temperature or by heating and pressing. It can also be applied when forming materials. In other words, friction materials using organic materials are
For example, it is common to heat and pressurize and mold a mixture of asbestos and binder resin on a backing plate, and at the same time adhere it to the backing plate. It is also conceivable to process grooves at the same time as molding and adhesion.

き種々の形状を採り得る。In addition, in order to prevent cracks from occurring in the friction material, it is desirable that the depth of the groove 6 be within several nanometers, preferably approximately 0.5 to 2 mm.With this depth, there will be no shortage. Provides anti-fade effect. The cross-sectional shape of this groove 6 is not particularly limited. That is, it can take various shapes as exemplified in (a) to (b) of FIG.
溝6の設置本数、設置ピッチ、配向方向も第3図の(イ

ッドである。The number of installed grooves 6, the installation pitch, and the orientation direction can also be arbitrarily set as shown in FIG. 3 (A) to (C). In the same figure, (a) shows three grooves extending in the radial direction of the disk, (b) shows a total of eight cross-oriented grooves, and (→ shows two grooves in the direction perpendicular to the disk radial axis at the center of the pad). It is a pad with grooves.
以上述べたこの発明の方法によれば、フェード対策用の
溝を、プレスして設けるので、溝加工の自動化を容易に
実現でき、また、1バッド当りの加工時間を僅か数秒に
短縮でき、さらに、臭気や粉塵等を回収する付帯設備も
不要になり、従って、加工コストの大巾に削減された安
価なパッドを得ることができる。According to the method of the present invention described above, since the grooves for preventing fade are formed by pressing, the automation of groove machining can be easily realized, and the machining time per pad can be shortened to just a few seconds. Additionally, there is no need for incidental equipment for collecting odors, dust, etc., and therefore, an inexpensive pad with significantly reduced processing costs can be obtained.

で、フェード防止効果、パッドの反り矯正効果等をより
高めることも可能になる。In addition, the number of grooves, installation pitch, orientation pattern, etc. can be easily changed to a more desirable state simply by replacing the mold, so it is also possible to further enhance the fade prevention effect, pad warp correction effect, etc.
