下部プレス部材２の中央部近傍には、２つのＶ字状の溝状部２１、２２が形成されており、２つの溝状部２１、２２の間には山状部２３が形成されている。前記２つの溝状部２１、２２の外側には平坦なケーブル設置部２４、２４が形成されている。
前記下部プレス部材２は、略直方体の部材を長手方向の断面がＷ字形状となるように加工して、前記２つのＶ字状の溝状部２１、２２と前記山状部２３とケーブル設置部２４、２４とが形成されたものであり、その長手方向の長さは、図１の（Ａ）に示した折り目加工前の平坦なフラットケーブルＦａの長さＬに等しく形成され、その短手方向の長さ（幅）は、図１の（Ａ）に示した折り目加工前の平坦なフラットケーブルの幅Ｗに等しく形成されている。 In FIG. 2 and FIG. 3 which showed the top view of the said lower press member 2,
Two V-shaped groove portions 21 and 22 are formed near the center of the lower press member 2, and a mountain-shaped portion 23 is formed between the two groove portions 21 and 22. . Flat cable installation portions 24 and 24 are formed outside the two groove portions 21 and 22.
The lower press member 2 is formed by processing a substantially rectangular parallelepiped member so that the cross section in the longitudinal direction is W-shaped, and installing the two V-shaped groove portions 21 and 22, the mountain-shaped portion 23, and a cable. The lengths in the longitudinal direction are equal to the length L of the flat flat cable Fa before crease processing shown in FIG. The length (width) in the hand direction is formed to be equal to the width W of the flat flat cable before crease processing shown in FIG.

前記断面のＷ字形状のうち、両側の２つのＶ字状の溝状部２１、２２の断面の挟み角度は、それぞれ、第１の折り目の角度と、第３の折り目の角度に対応した角度であり、中央の山状部２３の断面の挟み角度は、第２の折り目に対応した角度に設定されている。
前記両側のケーブル設置部２４、２４をコ字状に囲むようにケーブルガイド２５、２５が配設されている。
フラットケーブルの折り曲げ加工に際しては、まず、前記ケーブルガイド２５、２５に囲まれた領域に、破線で示した平坦なケーブルＦａを設置する。このようなケーブルガイド２５、２５があるため、平坦なケーブルＦａを所定の位置に設置しやすい。 Among the W-shaped cross sections, the sandwiching angles of the two V-shaped groove portions 21 and 22 on both sides are angles corresponding to the first fold angle and the third fold angle, respectively. The sandwiching angle of the cross section of the central mountain-shaped portion 23 is set to an angle corresponding to the second fold.
Cable guides 25 and 25 are disposed so as to surround the cable installation portions 24 and 24 on both sides in a U-shape.
In bending a flat cable, first, a flat cable Fa indicated by a broken line is installed in an area surrounded by the cable guides 25 and 25. Since there are such cable guides 25, 25, it is easy to install the flat cable Fa at a predetermined position.

次に、図２、図４を参照して、上部プレス部材３の構造を説明する。
図４に示したように、上部プレス部材３は、フレーム部３０に固定された外側押さえ部材３１と、フレーム部３０に対して相対的に上下動可能な中央押さえ部材３２とを備えている。中央押さえ部材３２は、十分な強さのバネ３３を用いて下方に付勢されている。
前記外側押さえ部材３１には、前記下部プレス部材２の断面形状に対応させて、断面形状がＷ字形状となるように加工して、下方に凸出した２つのＶ字形状の凸部３１１、３１２が形成されている。 Next, the structure of the upper press member 3 will be described with reference to FIGS.
As shown in FIG. 4, the upper press member 3 includes an outer pressing member 31 fixed to the frame portion 30 and a central pressing member 32 that can move up and down relatively with respect to the frame portion 30. The center pressing member 32 is biased downward by using a spring 33 having a sufficient strength.
The outer pressing member 31 has two V-shaped convex portions 311 that protrude downward and are processed so as to have a W-shaped cross-section corresponding to the cross-sectional shape of the lower press member 2. 312 is formed.

前記２つのＶ字状の凸部３１１、３１２の断面の挟み角度は、それぞれ、フラットケーブルに形成される第１の折り目Ｂ１の角度と、第３の折り目Ｂ３の角度に対応した角度に設定されている。
前記中央押さえ部材３２は、前記下部プレス部材２の中央の山状部２３の断面形状と、断面形状が逆Ｖ字形状となるように加工した凹部３２１が上方に凹設されている。前記凹部３２１の断面の挟み角度は、フラットケーブルに形成される第２の折り目Ｂ２に対応した角度に設定されている。 The sandwiching angles of the cross sections of the two V-shaped projections 311 and 312 are set to angles corresponding to the angle of the first fold line B1 formed on the flat cable and the angle of the third fold line B3, respectively. ing.
The central pressing member 32 is provided with a concave portion 321 that is processed so that the cross-sectional shape of the central mountain-like portion 23 of the lower press member 2 and the cross-sectional shape become an inverted V shape. The sandwiching angle of the cross section of the recess 321 is set to an angle corresponding to the second crease B2 formed in the flat cable.

以上のように構成された上部プレス部材３は、ハンドルが押し下げられていない状態では、中央押さえ部材３２は前記バネ３３によって下方に付勢されているので、図４の（Ａ）に示したように、所定の下限位置にあって、この下限位置では、中央押さえ部材３２の下端３２３は、外側押さえ部材３１の下端３１５とほぼ同一直線上にある。
そして、ハンドルを押し下げることによって、前記フレーム部３０が下降して、中央押さえ部材３２がフラットケーブルに当たりはじめると、前記バネ３３が徐々に圧縮されて、中央押さえ部材３２は、図４の（Ａ）に示した状態の位置から、図４の（Ｂ）に示した状態を通って、図４の（Ｃ）に示した状態まで押し上げられ得る。
図４の（Ｃ）に示した状態まで押し上げられると、中央押さえ部材３２の凹部３２１は外側押さえ部材３１の凸部３１１、３１２の傾斜面と一致した面を形成する位置になり、それ以上押し上げられることはない。 In the upper press member 3 configured as described above, the center pressing member 32 is biased downward by the spring 33 in a state where the handle is not pressed down, and therefore, as shown in FIG. In addition, the lower end 323 of the central pressing member 32 is substantially collinear with the lower end 315 of the outer pressing member 31 at the predetermined lower limit position.
When the frame portion 30 is lowered by pushing down the handle and the central pressing member 32 starts to hit the flat cable, the spring 33 is gradually compressed, and the central pressing member 32 is shown in FIG. It can be pushed up from the position shown in FIG. 4 to the state shown in FIG. 4C through the state shown in FIG.
When pushed up to the state shown in FIG. 4C, the concave portion 321 of the central pressing member 32 is positioned to form a surface that coincides with the inclined surfaces of the convex portions 311 and 312 of the outer pressing member 31, and is pushed up further. It will never be done.

以上のように構成されたフラットケーブル折り曲げ装置１を用いて、平坦なフラットケーブルに３つの折り目をつける加工操作を、図５を参照して説明する。図５には、フラットケーブル折り曲げ装置１の要部を示し、細部は省略した。
図５の（Ａ）において、
まず、下部プレス部材２のケーブル設置部２４、２４に平坦なケーブルＦａを置く。このとき、ケーブルガイド２５、２５に囲まれた所定の設置領域に平坦なケーブルＦａを置き易い。
その後、ハンドルを押し下げると、上部プレス部材３が図５の（Ａ）のように下降して平坦なケーブルＦａに接触する。ハンドルをさらに押し下げると、上部プレス部材３が図５の（Ｂ）のようにさらに下降するので、平坦なケーブルＦａの中央部分は、上部プレス部材３の中央押さえ部材３２と、下部プレス部材２の中央部の山状部２３との間に挟まれてプレスされ、山形の第２の折り目Ｂ２（中央の折り目）が、ほぼ形成される。 With reference to FIG. 5, a description will be given of a processing operation for making three folds on a flat flat cable using the flat cable bending apparatus 1 configured as described above. In FIG. 5, the principal part of the flat cable bending apparatus 1 is shown, and details are omitted.
In FIG. 5A,
First, the flat cable Fa is placed on the cable installation portions 24 and 24 of the lower press member 2. At this time, it is easy to place the flat cable Fa in a predetermined installation area surrounded by the cable guides 25, 25.
Thereafter, when the handle is pushed down, the upper press member 3 descends as shown in FIG. 5A and comes into contact with the flat cable Fa. When the handle is further pushed down, the upper press member 3 is further lowered as shown in FIG. 5B, so that the central portion of the flat cable Fa is located between the central pressing member 32 of the upper press member 3 and the lower press member 2. A second crease B2 (center crease) having a chevron is substantially formed by being sandwiched and pressed between the central chevron 23.

その後、ハンドルをさらに押し下げると、フレーム部３０が下降して、上部プレス部材３の中央押さえ部材３２を付勢するバネ３３が、ハンドル操作による下方へのプレス圧力に負けて圧縮され始める。
ハンドルをさらに押し下げると、フレーム部３０がさらに下降して、上部プレス部材３のフレーム部３０に固定された外側押さえ部材３１がさらに下降し、図５の（Ｃ）のように、フラットケーブルは、上部プレス部材３の外側押さえ部材３２と、下部プレス部材２の２つのＶ字状の溝状部２１、２２との間に挟まれてプレスされ、第１の折り目Ｂ１と第３の折り目Ｂ３（側部の折り目）が形成される。 Thereafter, when the handle is further pushed down, the frame portion 30 is lowered, and the spring 33 that biases the central pressing member 32 of the upper press member 3 starts to be compressed against the downward pressing pressure by the handle operation.
When the handle is further pushed down, the frame portion 30 is further lowered, and the outer pressing member 31 fixed to the frame portion 30 of the upper press member 3 is further lowered. As shown in FIG. It is sandwiched and pressed between the outer pressing member 32 of the upper press member 3 and the two V-shaped groove portions 21 and 22 of the lower press member 2, and the first fold line B1 and the third fold line B3 ( Side folds) are formed.

図５の（Ｂ）の状態から図５の（Ｃ）の状態に移行する間、フラットケーブルの中央部分は、上部プレス部材３の中央押さえ部材３２と、下部プレス部材２の中央部の山状部２３との間に挟まれてプレスされた状態であるので、ずれることは防止され、３つの折り目が規定の位置に形成されるのである。   During the transition from the state shown in FIG. 5B to the state shown in FIG. 5C, the central portion of the flat cable has a central pressing member 32 of the upper press member 3 and a mountain shape at the central portion of the lower press member 2. Since it is sandwiched and pressed between the portions 23, it is prevented from shifting, and three folds are formed at specified positions.

なお、図２、４に示したように、上部プレス部材３の中央押さえ部材３２の凹部３２１の中央部分には、逃げ溝３２４が形成されているので、図４の（Ｃ）の状態で形成されるフラットケーブルの第２の折り目Ｂ２は、丸みを帯びることなく明瞭な折り目が形成される。
同様に、下部プレス部材２の２つのＶ字状の溝状部２１、２２のそれぞれの中央部分にも、逃げ溝２１１、２２１が形成されているので、フラットケーブルの第１と第３の目Ｂ１，Ｂ３は、丸みを帯びることなく明瞭な折り目が形成される。 As shown in FIGS. 2 and 4, a relief groove 324 is formed in the central portion of the concave portion 321 of the central pressing member 32 of the upper press member 3, so that it is formed in the state of FIG. A clear crease is formed in the second crease B2 of the flat cable without being rounded.
Similarly, since the relief grooves 211 and 221 are also formed in the central portions of the two V-shaped groove portions 21 and 22 of the lower press member 2, the first and third eyes of the flat cable are formed. B1 and B3 are formed with clear folds without being rounded.

以上のようにして、フラットケーブルに３つの折り目をつけた後、ハンドルを押し上げると、上部プレス部材３は下部プレス部材２から離れて上昇するので、折り目のついたフラットケーブルＦｂを取り出すことができる。
なお、上部プレス部材３の中央押さえ部材３２を進退可能に設けたが、中央押さえ部材３２をフレーム部３０に固定して、外側押さえ部材３１を進退可能に設けてもよい。
When the handle is pushed up after three folds are made on the flat cable as described above, the upper press member 3 is lifted away from the lower press member 2, so that the creased flat cable Fb can be taken out. .
Although the central pressing member 32 of the upper press member 3 is provided so as to be able to advance and retract, the central pressing member 32 may be fixed to the frame portion 30 and the outer pressing member 31 may be provided so as to be able to advance and retract.

以上の実施例１においては、上部プレス部材３の中央押さえ部材を進退可能に配設したが、図６に示した実施例２のように、上部プレス部材２Ｂは一体に形成し、下部プレス部材３Ｂの中央押さえ部材３２Ｂを進退可能に配設してもよい。
In the first embodiment described above, the central pressing member of the upper press member 3 is disposed so as to be able to advance and retract.
