Description
本発明は、自動車、各種産業用機械等の制動に用いられるブレーキシューの製造方法に関する。 The present invention relates to a method for manufacturing a brake shoe used for braking automobiles, various industrial machines and the like.
例えば、自動車、各種産業用機械等の制動としてブレーキシューが使用されている。
従来のブレーキシューは、特許文献１に示されるように、円板上の金属製ブランクの外周部に、外周面に前記ブランクの板厚よりも大きい溝幅をもつ凹溝をその円周方向に形成し、かつ該凹溝の内底部に溝形成用刃部をその円周方向に突設してなる予成形用ローラーダイスの、前記凹溝及び溝形成用刃部を押し付けて、前記ブランクの外周部全周に前記溝形成用刃部により外周溝を付ける予成形工程と、前記ブランクの外周溝に、外周面に拡開用刃部をその円周方向に突設してなる拡開成形用ローラーダイスの、前記拡開用刃部を押し付けることにより、前記ブランクの外周部を板厚方向に二つに割りながら拡開してウェブとこのウェブの外周部にリムを成形する拡開成形工程と、前記ウェブとリムとを所要形状に切断することにより部分円弧状のシューリムと、このシューリムの内周から突設したシューリブを有するブレーキシューを形成する工程とを備えているブレーキシューが知られている。
For example, brake shoes are used for braking automobiles and various industrial machines.
As shown in Patent Document 1, the conventional brake shoe has a groove in the outer circumferential portion of a metal blank on a circular plate having a groove width larger than the thickness of the blank on the outer circumferential surface in the circumferential direction. And pressing the concave groove and the groove forming blade portion of a pre-rolling roller die formed by projecting a groove forming blade portion in the circumferential direction on the inner bottom portion of the concave groove, A pre-molding step in which an outer peripheral groove is provided by the groove forming blade portion on the entire outer periphery, and an expansion molding formed by projecting an expanding blade portion on the outer peripheral surface of the blank in the circumferential direction of the blank. Of the roller die for expansion, expanding the outer peripheral portion of the blank while dividing the outer peripheral portion of the blank into two in the plate thickness direction, and forming a rim on the outer periphery of the web and the web Partial circle by cutting the process and the web and rim into the required shape And Jo of the shoe rim, the brake shoe and a step of forming a brake shoe having a Shuribu which projects from the inner periphery of the shoe rim is known.
しかしながら、上記に示す方法でブレーキシューを製造する場合、使用する材料（金属板）を打ち抜き法でブランク（摩擦部材支持体）を作製するため、最終的にはブレーキシューの大きさにより異なるが、約７０％程度の材料を廃棄処分することになり不経済であり、得られるブレーキシューが高価になるという問題点があった。 However, when manufacturing a brake shoe by the method shown above, a blank (friction member support) is produced by punching out the material (metal plate) to be used, which ultimately depends on the size of the brake shoe. About 70% of the material is discarded, which is uneconomical and the resulting brake shoe is expensive.
本発明は、廃棄処分する材料をできるだけ少なくして、経済的で安価なブレーキシューの製造方法を提供するものである。 The present invention provides an economical and inexpensive method for manufacturing a brake shoe with the least amount of material to be disposed of.
本発明は、短冊形状の金属板を、円筒状に形成した後、該円筒形状金属板の高さ方向のほぼ中央部に圧力をかけてくぼみを形成し、次いで上下面から圧力をかけて前記くぼみ部分を押しつぶして内面に突出部分を形成し、その後該円筒形状金属板外周の平坦部分に摩擦部材を固着するか又は一体成形することを特徴とするブレーキシューの製造方法に関する。
また、本発明は、突出部分が、圧接後全周又は部分的に溶接を施したものである前記のブレーキシューの製造方法に関する。
In the present invention, after a strip-shaped metal plate is formed into a cylindrical shape, a depression is formed by applying pressure to a substantially central portion in the height direction of the cylindrical metal plate, and then pressure is applied from the upper and lower surfaces. The present invention relates to a method for manufacturing a brake shoe, in which a hollow portion is crushed to form a protruding portion on the inner surface, and then a friction member is fixed or integrally formed on a flat portion on the outer periphery of the cylindrical metal plate.
The present invention also relates to the above-described method for manufacturing a brake shoe, wherein the projecting portion is welded entirely or partially after pressure welding.
本発明の方法により得られるブレーキシューは、廃棄処分する材料（金属板）をできるだけ少なくすることができるため、経済的で安価なブレーキシューが得られ、工業的に極めて好適である。 Since the brake shoe obtained by the method of the present invention can reduce the material (metal plate) to be disposed of as much as possible, an economical and inexpensive brake shoe can be obtained, which is extremely suitable industrially.
本発明で用いられる短冊形状（長方形）の金属板の材質は、スチール板、アルミニウム板、真鍮板等の延性のある金属板であれば特に制限はないが、これらのうちスチール板又はアルミニウム板を用いることが好ましい。
本発明において、短冊形状の金属板を円筒状に形成する方法は特に制限はないが、例えば、該短冊形状の金属板を長さ方向にロール加工することにより円筒状にすることができる。
The material of the strip-shaped (rectangular) metal plate used in the present invention is not particularly limited as long as it is a ductile metal plate such as a steel plate, an aluminum plate, a brass plate, etc. Among them, a steel plate or an aluminum plate is used. It is preferable to use it.
In the present invention, the method of forming the strip-shaped metal plate into a cylindrical shape is not particularly limited. For example, the strip-shaped metal plate can be formed into a cylindrical shape by rolling in the length direction.
短冊形状の金属板を円筒状に形成した後、高さ方向のほぼ中央部に圧力をかけてくぼみを形成するが、このくぼみの形状はＵ字状又はＶ字状であることが好ましく、該くぼみを形成する方法としては、Ｕ字状又はＶ字状に加工したローラーダイスを回転させながら押し付けて形成することが好ましい。 After the strip-shaped metal plate is formed into a cylindrical shape, a depression is formed by applying pressure to a substantially central portion in the height direction, and the shape of the depression is preferably U-shaped or V-shaped, As a method for forming the indentation, it is preferable to press and form a roller die processed into a U shape or a V shape.
次に、円筒形状金属板の上下面から圧力をかけて前記くぼみ部分を押しつぶして内面に突出部分を形成するが、圧力をかける方法としてはプレスによる方法が好ましいが、くぼみ部分を押しつぶすことが可能であればこの方法に制限することはない。 Next, pressure is applied from the upper and lower surfaces of the cylindrical metal plate to crush the indented portion to form a protruding portion on the inner surface. As a method of applying pressure, a method using a press is preferable, but the indented portion can be crushed. If so, there is no limit to this method.
なお、本発明においては、ブレーキシューの強度や剛性を上げるため前記突出部分をシームレス溶接、スポット溶接等により円周方向に全周溶接するか又は必要部分のみを部分的に溶接することが好ましい。 In the present invention, in order to increase the strength and rigidity of the brake shoe, it is preferable that the protruding portion is welded all around in the circumferential direction by seamless welding, spot welding or the like, or only a necessary portion is partially welded.
上記で得られたリング状金属板の平坦部に固着して使用する摩擦部材の材料は、一般に公知の材料が用いられ、例えばスチール繊維、黄銅繊維、銅繊維、アラミド繊維、アクリル繊維、フェノール繊維、セラミック繊維、ロックウール、チタン酸カリウム繊維、カーボン繊維等の繊維状物質、フェノール樹脂、エポキシ樹脂、メラミン樹脂、カシュー樹脂等の熱硬化樹脂やＮＢＲ、ＳＢＲ等のゴム組成分を含む結合剤、フリクションダストなどの有機質摩擦調整剤、硫酸バリウム、黒鉛、三硫化アンチモン等の無機質摩擦調整剤などが用いられる。 As a material of the friction member fixed to the flat part of the ring-shaped metal plate obtained as described above, generally known materials are used, for example, steel fiber, brass fiber, copper fiber, aramid fiber, acrylic fiber, phenol fiber. A binder containing a fibrous material such as ceramic fiber, rock wool, potassium titanate fiber, carbon fiber, thermosetting resin such as phenol resin, epoxy resin, melamine resin, cashew resin, and rubber composition such as NBR, SBR, Organic friction modifiers such as friction dust, inorganic friction modifiers such as barium sulfate, graphite, and antimony trisulfide are used.
上記の材料の他に、必要に応じて黄銅、銅等の金属粉が添加される。
なお、上記摩擦部材の材料の配合割合は、摩擦特性により異なり適宜決定され、特に制限はない。
円筒形状金属板外周の平坦部分への摩擦部材の取り付けは、固着方法又は一体成形による方法があるが、このうち固着方法については、例えば、リベット止め、接着剤等で固着することができる。もし、接着する場合、摩擦部材の接着強度を上げるため、摩擦部材を接着する前にリング状金属板の外周をローレットなどの加工を施しておくことが好ましい。
In addition to the above materials, metal powder such as brass and copper is added as necessary.
Note that the blending ratio of the material of the friction member varies depending on the friction characteristics and is appropriately determined, and is not particularly limited.
The friction member can be attached to the flat portion of the outer periphery of the cylindrical metal plate by an adhering method or an integral molding method. Of these, the adhering method can be adhering by, for example, riveting or adhesive. In the case of bonding, in order to increase the bonding strength of the friction member, it is preferable that the outer periphery of the ring-shaped metal plate is processed such as knurling before bonding the friction member.
