れている。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In the wire cutter A of this embodiment, as shown in FIG. 1, upper and lower mounting plates 2 and 3 are fitted to a lower end side of a rotary shaft 1 with a space therebetween, and a lower mounting plate 3 and an upper mounting plate 3 are mounted. Two wires 5 between the hook 4 fixed to
18 at the position eccentric to the axis of the rotary shaft 1 by the same size.
Tensioned in a posture parallel to the rotation axis 1 with an angular interval of 0 °.
【0008】そして、回転軸1の上端部が、図示しない
インバータモータによって駆動されるスピンドル7の下
端に取り付けられるようになっている。The upper end of the rotary shaft 1 is attached to the lower end of a spindle 7 driven by an inverter motor (not shown).
【0009】本実施例では、ワイヤ5に線径0.3mm の
ピアノ線が使用され、また、各ワイヤ5の偏心寸法すな
わちワイヤ5の回転半径が13mmとなっている。In this embodiment, a piano wire having a wire diameter of 0.3 mm is used as the wire 5, and the eccentric dimension of each wire 5, that is, the turning radius of the wire 5 is 13 mm.
【0010】次に、本実施例のワイヤカッタAを自動車
のハンドルのバリ取りに使用した例を説明する。Next, an example in which the wire cutter A of this embodiment is used for deburring a steering wheel of an automobile will be described.
【0011】握り部が合成ゴムのインサート成形により
形成されたハンドルaは、図2に示すように、加工板9
上に突設された取付治具10にその中心部を取り付ける
ことによって、加工板9から浮いた水平姿勢で固定され
る。As shown in FIG. 2, the handle a whose grip portion is formed by insert molding of synthetic rubber has a processed plate 9
By mounting the central portion of the mounting jig 10 projecting upward, the workpiece 10 is fixed in a horizontal posture floating from the processing plate 9.
【0012】そして、ワイヤカッタAのワイヤ5を、図
1に示すように、バリbの出ているハンドルaの外周面
に当て、ワイヤカッタA自身をハンドルaの外周に倣っ
て図2の矢線x方向に移動させつつ、スピンドル7を駆
動してワイヤカッタAを回転軸1回りに矢線y方向に回
転させると、回転するワイヤ5によってバリbが切除さ
れる。Then, as shown in FIG. 1, the wire 5 of the wire cutter A is applied to the outer peripheral surface of the handle a where the burr b is projected, and the wire cutter A itself is imitated on the outer periphery of the handle a and the arrow x in FIG. When the wire cutter A is rotated around the rotation axis 1 in the arrow y direction while moving in the direction, the burr b is cut off by the rotating wire 5.
【0013】この場合、インバータモータへの入力周波
数を制御してスピンドル7の回転数を調節することによ
りワイヤ5の周速を種々変えたところ、周速が小さいほ

周速が大きいほど逆に切削面は平滑になるが倣うのが難
しくなる傾向にあり、このようなバリ取りにおいて、ハ
ンドルaの外周に良く倣わせ、かつ、平滑な切削面を得
るには、ワイヤ5の周速を100〜150m/min にす
るのが好適であることが確認された。In this case, when the peripheral speed of the wire 5 is variously changed by controlling the input frequency to the inverter motor and adjusting the rotational speed of the spindle 7, the smaller the peripheral speed is, the easier it is to follow the outer periphery of the handle a. The cutting surface is rough,
On the contrary, the higher the peripheral speed, the smoother the cutting surface becomes, but it tends to be difficult to follow. In such deburring, in order to follow the outer periphery of the handle a well and obtain a smooth cutting surface, It was confirmed that it is preferable to set the peripheral speed of the wire 5 to 100 to 150 m / min.
【0014】次に、ワイヤ5の本数を4本にして90°
間隔で緊張したところ、2本のときよりも切削面がさら
に平滑にできることが確認された。ただし、余り本数が
多くなると大きなバリが取りにくくなる傾向が見られ
た。Next, the number of wires 5 is changed to 4 and 90 °
When tension was applied at intervals, it was confirmed that the cutting surface could be made smoother than when two pieces were used. However, when the number was too large, it was difficult to remove large burrs.
【0015】また、ワイヤ5の回転半径を8mmと小さく
して、上記の13mmの場合と比較したところ、8mmの場

aに倣いやすい傾向が見られたが、8mmの場合でもバリ
取りに対応できることが確認された。その場合、ワイヤ
5の周速は60〜100m/min が好適である。Further, when the radius of gyration of the wire 5 is reduced to 8 mm and compared with the case of 13 mm described above, there is a tendency that the case of 8 mm is easier to cut, and the case of 13 mm is more likely to follow the handle a. Although it was seen, it was confirmed that deburring can be performed even with 8 mm. In that case, the peripheral speed of the wire 5 is preferably 60 to 100 m / min.
【0016】さらに、ワイヤ5の線径については、細い
ほど平滑な切削面が得られると思われる。現状では、例
えば線径0.1mm のピアノ線では強度的に問題がある
が、強度の点がクリアされれば細い線径のワイヤを使用
するのが好ましい。Further, regarding the wire diameter of the wire 5, it is considered that a smoother cutting surface can be obtained as the wire diameter becomes smaller. At present, for example, a piano wire having a wire diameter of 0.1 mm has a problem in strength, but if the strength is cleared, it is preferable to use a wire having a thin wire diameter.
【0017】なお、本発明は、上記実施例に示したハン
ドルaのバリ取りに限らず、合成ゴムや合成樹脂等の軟
質材製品のバリ取り全般に広く適用することができる。The present invention is not limited to the deburring of the handle a shown in the above embodiment, but can be widely applied to the general deburring of soft material products such as synthetic rubber and synthetic resin.

が確認されている。In addition to deburring, it can also be used for cutting the outer surface of a soft material product as described above. In that case,
It has been confirmed that it is preferable to set the peripheral speed of the wire 5 to 200 to 400 m / min when the turning radius of the wire 5 is 13 mm, and to 150 to 250 m / min when the turning radius is 8 mm. .

に製造できる効果がある。As described above, when the wire cutter of the present invention is used, deburring of a soft material product and its own cutting process can be efficiently performed, and a smooth cutting surface can be finished. Further, the cutter itself has a simple structure in which the wire is tensioned at the eccentric position of the rotary shaft, and has an effect that it can be manufactured at low cost.
