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, various industrial machines, and the like.

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.

上記の欠点を解消するために本発明者らは、特許文献２及び３に示されるように、短冊形状の金属板を、その幅のほぼ中央部を長さ方向にＶ字形状に折り曲げた後、該Ｖ字形状金属板の左右両側面の上端から下端の間の一部分を長さ方向に外側に折り返し、その後Ｖ字形状部分の外側から内側に圧力をかけて圧接し、平坦部とそれに垂直な突出部分を有するＴ字形状に加工し、さらに突出部分が内側になるようにリング状又は円弧状に加工し、次いでリング状又は円弧状外側表面の平坦部に摩擦部材を固着するか又は一体成形してブレーキシューを製造する方法を考案した。   In order to eliminate the above-mentioned drawbacks, the present inventors, as shown in Patent Documents 2 and 3, after bending a strip-shaped metal plate into a V-shape in the longitudinal direction at a substantially central portion of its width. The part between the upper end and the lower end of the left and right side surfaces of the V-shaped metal plate is folded back outward in the length direction, and then pressed by applying pressure from the outer side to the inner side of the V-shaped part. Processed into a T-shape having a protruding portion, and further processed into a ring shape or an arc shape so that the protruding portion is inside, and then a friction member is fixed to the flat portion of the ring-shaped or arc-shaped outer surface or integrated. A method of manufacturing a brake shoe by molding was devised.

It is an economical and inexpensive arc-shaped brake shoe, and is extremely suitable industrially.

本発明で製造される円弧状ブレーキシューは、単一の円弧状ブレーキシューが得られる寸法を有する短尺のブロック状金属Ａを用いて１個ずつ単一の円弧状ブレーキシューを製造してもよく、また単一のリング状加工品が得られる寸法を有する短尺のブロック状金属Ｂを用いて、これをリング状に形成し、その後分割して２〜３個の円弧状ブレーキシューを製造してもよく、さらに複数の円弧状ブレーキシューが得られる寸法を有する長尺のブロック状金属を用いて必要とする大きさの単一の円弧状ブレーキシューが得られる部分で切断して多数（４個以上）の円弧状ブレーキシュー、即ち、１枚のブロック状金属から単一の円弧状ブレーキシューを多数製造してもよい。   The arc-shaped brake shoes manufactured according to the present invention may be manufactured one by one using a short block-shaped metal A having a dimension capable of obtaining a single arc-shaped brake shoe.

本発明で用いられる短尺のブロック状金属Ａ、Ｂ又は長尺のブロック状金属の材質は、スチール、アルミニウム、真鍮板等の延性のある金属であれば特に制限はないが、これらのうちスチール又はアルミニウムを用いることが好ましい。   The material of the short block metal A or B or the long block metal used in the present invention is not particularly limited as long as it is a ductile metal such as steel, aluminum, or a brass plate. It is preferable to use aluminum.

本発明において、短尺のブロック状金属Ａ、Ｂ又は長尺のブロック状金属をＴ字形状に加工する場合、引き抜き法により加工するが、この加工方法は、例えば、上下に２つの金型を使用し、ブロック状金属を加熱、加圧しながら前記の金型間を引き抜き加工するものであり、その加工方法の一例として下記に示すように、引き抜きを２度行って加工する方法がある。この方法は、先ず１回目の引き抜き法として、一方の金型は押圧部分（ブロック状金属の平坦部を形成する部分）が平坦で、他方は中央部にくぼみを設けた金型をそれぞれ使用し、これらの金型間を一般的に公知の加熱加圧条件で、ブロック状金属を引き抜き、ブロック状金属の片側中央部上面が円弧状の突起を形成する。   In the present invention, when a short block metal A, B or a long block metal is processed into a T-shape, it is processed by a drawing method. This processing method uses, for example, two upper and lower molds. Then, the above metal molds are drawn while heating and pressurizing the block-shaped metal. As an example of the processing method, there is a method of performing the drawing twice as shown below. In this method, first, as a first drawing method, one die uses a die having a flat pressing portion (a portion forming a flat portion of a block-like metal) and the other having a depression at the center. The block-shaped metal is drawn between these molds under generally known heating and pressing conditions, and the upper surface of one central portion of the block-shaped metal forms an arc-shaped protrusion.

次に、２回目の引き抜きを行うが、この方法は、一方の金型には円周方向にＴ字形状の平坦部を形成するためのくぼみを設けた金型を使用し、他方の金型には円周方向に平坦部に対して垂直な突出部分を形成するためのくぼみを設けた金型をそれぞれ使用し、これらの金型間を一般的に公知の加熱加圧条件で、前記で得た片側中央部に突起を形成したブロック状金属を引き抜くことにより、平坦部とそれに垂直な突出部分を有するＴ字形状加工品を得ることができる。   Next, the second drawing is performed. In this method, a mold having a depression for forming a T-shaped flat portion in the circumferential direction is used for one mold, and the other mold is used. Each of the molds provided with a recess for forming a projecting portion perpendicular to the flat portion in the circumferential direction, and between these molds, generally known heating and pressing conditions, By drawing out the obtained block-like metal having a protrusion formed on the central portion on one side, a T-shaped processed product having a flat portion and a protruding portion perpendicular to the flat portion can be obtained.

引き抜き法でＴ字形状加工品を作製する方法として上記では、引き抜き法を２回で行う例で説明したが、引き抜き法による場合は、塑性変形抵抗が相当あり、材料が切れるおそれがあるため、必要に応じて複数回の引き抜き法で行ってもよい。
なお、本発明においては、上下に２つの金型を使用してＴ字形状加工品を作製する他に、一体型のダイスの円錐状の穴又は複数に分割したダイス（組立構造）で作製した穴の部分を引き抜く方法でＴ字形状加工品を得ることができる。 In the above description, the method for producing a T-shaped processed product by the drawing method has been described in an example in which the drawing method is performed twice. However, in the case of the drawing method, plastic deformation resistance is considerable, and the material may be cut. You may carry out by the drawing method of multiple times as needed.
In the present invention, in addition to producing a T-shaped processed product using two upper and lower dies, it is produced with a conical hole of an integrated die or a die (assembled structure) divided into a plurality of dies. A T-shaped processed product can be obtained by pulling out the hole portion.

上記で得られるＴ字形状加工品における平坦部とは得られるブレーキシューのリムに相当するもので、また平坦部に垂直な突出部分とはブレーキシューのシューウェブに相当するものである。
Ｔ字形状に加工した後、突出部分が内側になるように円弧状に加工するが、この加工方法についてはロール加工が最適であるが、必ずしもこの方法に限る必要はない。 The flat portion in the T-shaped processed product obtained above corresponds to the rim of the obtained brake shoe, and the protruding portion perpendicular to the flat portion corresponds to the shoe web of the brake shoe.
After processing into a T-shape, processing is performed in an arc shape so that the protruding portion is on the inside, but roll processing is optimal for this processing method, but it is not necessarily limited to this method.

上記で得られた円弧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。
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。 As a material of the friction member fixed to the flat portion of the arc-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. Binders containing fibrous materials such as ceramic fibers, rock wool, potassium titanate fibers, carbon fibers, thermosetting resins such as phenol resins, epoxy resins, melamine resins, cashew resins, and rubber components such as NBR, SBR, Organic friction modifiers such as friction dust, inorganic friction modifiers such as barium sulfate, graphite, and antimony trisulfide are used.
In addition to the above materials, metal powder such as brass and copper is added as necessary.
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.

円弧状金属加工品外側表面の平坦部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円弧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。   The friction member can be attached to the flat portion of the outer surface of the arc-shaped metal workpiece by an adhering method or a method by integral molding. Of these, the adhering method can be adhering with, for example, riveting or an adhesive. . If bonded, in order to increase the bonding strength of the friction member, it is preferable that the outer periphery of the arc-shaped metal plate is processed such as knurling before bonding the friction member.
