Description
本発明は、長尺の金属線材を通線させて連続熱処理する金属線材の熱処理装置に関するものである。 TECHNICAL FIELD The present invention relates to a heat treatment apparatus for a metal wire that is continuously heat-treated by passing a long metal wire.
従来、長尺の金属線材に所定の性質を得るために行なう、焼なましや焼入れおよび焼戻し等の熱処理は、熱処理炉内にパイプを横設し、該パイプ内を水素ガスや窒素ガスなどの非酸化雰囲気に保持して、長尺の金属線材をパイプ内の長手方向に通線させることにより連続熱処理する方法が一般的に用いられている。この連続熱処理の方法では、前工程の引抜き工程で金属線材表面に塗布されるステアリン酸ナトリウム等の石鹸系、あるいはステアリン酸カルシウム等の金属石鹸系を主成分とする伸線潤滑剤の一部がパイプ内に持ち込まれて溶融分解し、パイプ内面に付着することがある。そして、この付着物とパイプ内を通線する金属線材とが直接接触し、金属線材の表面にスリ疵が発生する場合があった。 Conventionally, heat treatment such as annealing, quenching and tempering performed to obtain a predetermined property on a long metal wire has a pipe placed horizontally in a heat treatment furnace, and the pipe is filled with hydrogen gas or nitrogen gas. A method of continuous heat treatment is generally used by maintaining a non-oxidizing atmosphere and passing a long metal wire in the longitudinal direction in the pipe. In this continuous heat treatment method, a part of a wire-drawing lubricant mainly composed of a soap system such as sodium stearate or a metal soap system such as calcium stearate applied to the surface of the metal wire in the drawing process of the previous process is a pipe. It may be brought in and melted and decomposed to adhere to the inner surface of the pipe. And this deposit | attachment and the metal wire which penetrates the inside of a pipe may contact directly, and the surface of a metal wire may generate | occur | produce a crack.
このような金属線材の表面疵を防止するために、熱処理炉内のパイプ内面の所定周長に亘って耐熱クロスで覆いながら金属線材を通線させて連続熱処理する方法が提案されている（特許文献１）。特許文献１では、熱処理の前段階で金属線材の表面を洗浄する洗浄装置を用いることで伸線潤滑剤を除去するため、付着物に起因するスリ疵のリスクを低減できる。また、熱処理炉内のパイプ内面を耐熱クロスで所定周長覆うことで、パイプ内周面と金属線材とが直接接触することを抑制し、金属線材への表面疵を防止するという効果もある。 In order to prevent such surface flaws of the metal wire, a method has been proposed in which the metal wire is passed through and continuously heat-treated while being covered with a heat-resistant cloth over a predetermined circumference of the pipe inner surface in the heat treatment furnace (patent) Reference 1). In Patent Document 1, since the wire drawing lubricant is removed by using a cleaning device that cleans the surface of the metal wire in the previous stage of the heat treatment, it is possible to reduce the risk of scratches caused by the deposits. Further, by covering the inner surface of the pipe in the heat treatment furnace with a heat resistant cloth for a predetermined circumference, it is possible to suppress direct contact between the inner peripheral surface of the pipe and the metal wire, and to prevent surface flaws on the metal wire.
しかしながら、本発明者の検討によると、特許文献１に開示される熱処理の前段階で行う金属表面の洗浄では、伸線潤滑剤の滓が完全に落ち切らずに炉内へ持ち込まれ、耐熱クロス上に堆積する場合があることを確認した。そして、この堆積した伸線潤滑剤の滓が金属線材表面と直接接触することにより、金属線材の表面疵を誘発するという問題があった。
また、特許文献１で開示される洗浄装置を用いる場合には、金属線材の表面を長時間洗浄槽に浸漬して洗浄し続けなければ伸線潤滑剤を落とすことができず、装置の長大化や工数の増加が重なり経済的に不利である。
本発明の目的は、コンパクトな構成で且つ少ない工数で金属線材表面に付着した伸線潤滑剤を除去でき、伸線潤滑剤の炉内への持ち込みの問題を解決し、金属線材の表面疵を防止できる金属線材の熱処理装置を提供することである。
However, according to the study of the present inventor, in the metal surface cleaning performed in the previous stage of the heat treatment disclosed in Patent Document 1, the wrinkles of the wire drawing lubricant are brought into the furnace without being completely removed, and the heat resistant cloth It was confirmed that there was a case of depositing on top. In addition, there is a problem in that the surface defects of the metal wire are induced when the accumulated wire drawing lubricant wrinkles come into direct contact with the surface of the metal wire.
Further, when the cleaning device disclosed in Patent Document 1 is used, the wire drawing lubricant cannot be removed unless the surface of the metal wire is immersed in the cleaning bath for a long time and the wire drawing lubricant is dropped. And the increase in man-hours is economically disadvantageous.
The object of the present invention is to remove the wire drawing lubricant adhering to the surface of the metal wire in a compact configuration and with a small number of man-hours, solve the problem of bringing the wire drawing lubricant into the furnace, and reduce the surface defects of the metal wire. An object of the present invention is to provide a heat treatment apparatus for metal wires that can be prevented.
本発明者は、伸線潤滑剤の炉内への持ち込みの問題を検討し、加熱炉の前段に前記金属線材の表面を研磨する研磨機と、前記金属線材の表面を拭取る拭取り機とを順に配置する構成を採用することで、伸線潤滑剤の炉内への持ち込みを抑制し、金属線材の表面疵を大きく改善できることを見出し本発明に到達した。 The present inventor has examined the problem of bringing a wire drawing lubricant into the furnace, a polishing machine that polishes the surface of the metal wire in the front stage of the heating furnace, and a wiping machine that wipes the surface of the metal wire.

また、前記拭取り機は、通線方向に固定された拭取り布または紙で前記金属線材の表面に押圧しながら前記金属線材を通線して拭取るものであることが好ましい。
また、本発明においては、前記研磨機と前記拭取り機との間に、前記金属線材の表面を溶媒により洗浄する洗浄機を配置することが好ましい。
また、前記溶媒は、酸性水を用いることが好ましい。
また、前記溶媒に超音波を印加することが好ましい。

Moreover, in this invention, it is preferable to arrange | position the washing machine which wash | cleans the surface of the said metal wire with a solvent between the said polishing machine and the said wiping machine.
Moreover, it is preferable to use acidic water as the solvent.

本発明によれば、加熱炉の前段に金属線材の表面を研磨する研磨機と金属線材の表面を拭取る拭取り機とを順に配置することで、金属線材表面の塗布されている伸線潤滑剤を効率的に除去できる。これにより本発明は、伸線潤滑剤の炉内への持ち込みの問題を解決し、金属線材の表面疵を飛躍的に改善することができ、金属線材の量産化にとって欠くことのできない技術となる。 According to the present invention, the wire lubrication applied to the surface of the metal wire is performed by sequentially arranging a polishing machine for polishing the surface of the metal wire and a wiping machine for wiping the surface of the metal wire in front of the heating furnace. The agent can be removed efficiently. As a result, the present invention solves the problem of bringing the wire drawing lubricant into the furnace, can dramatically improve the surface flaw of the metal wire, and becomes an indispensable technique for mass production of the metal wire. .
本発明の重要な特徴は、金属線材の連続熱処理装置において、加熱炉の前段に金属線材の表面を研磨する研磨機と、金属線材の表面を拭取る拭取り機とを順に配置する構成を採用したことにある。
例えば、前工程で金属線材の表面に付着したステアリン酸カルシウム等の金属石鹸系を主成分とする伸線潤滑剤は、金属線材表面に塊状として固着しているものや、金属線材表面に薄く膜をつくるように付着しているものがある。上記で説明したように、この伸線潤滑剤の塊や薄い膜を除去するために、特許文献１に記載されるような洗浄装置を用いる場合は、金属線材の全面を長時間洗浄槽に浸漬して洗浄し続けなければ完全に落とすことができず、装置の長大化や工数の増加が重なり経済的に不利である。
An important feature of the present invention is that in a continuous heat treatment apparatus for a metal wire, a configuration is adopted in which a polishing machine for polishing the surface of the metal wire and a wiping machine for wiping the surface of the metal wire are sequentially arranged in the front stage of the heating furnace. It is to have done.
For example, a wire drawing lubricant mainly composed of a metal soap system such as calcium stearate adhering to the surface of the metal wire in the previous process is fixed as a lump on the surface of the metal wire, or a thin film is formed on the surface of the metal wire. Some are attached to make. As explained above, when using a cleaning apparatus as described in Patent Document 1 to remove this lump of drawn lubricant and thin film, the entire surface of the metal wire is immersed in a cleaning bath for a long time. If the cleaning is not continued, it cannot be completely removed, which is disadvantageous economically due to the increase in the length of the apparatus and the increase in man-hours.
図１は、本発明の熱処理装置の一例を示す模式図である。図１において、複数本のコイル（図示せず）に巻かれた金属線材１は、並列にそれぞれのコイルから連続的に引き出されて研磨機２に入る。そして、前工程の伸線工程で金属線材表面に塗布された伸線潤滑剤が引き剥がされ、次いで拭取り機３により研磨機２で落としきれなかった細かな伸線潤滑剤が拭き取られる。続いて、それぞれの金属線材１は、パイプが並列に複数本横設（図示せず）してある加熱炉４を通り、次いで冷却装置５を通って冷却され、所定の特性を得るための熱処理をされた後に再びそれぞれのコイルに巻き取られる。ここで、加熱炉４と冷却装置５内部の金属線材を通線させるパイプ内部は、非酸化雰囲気に保持され、金属線材１の表面酸化を抑制する。
本発明の金属線材の熱処理装置は、複数本の金属線材を並列で同時に熱処理することにより、生産性を大幅に向上することができる。
FIG. 1 is a schematic view showing an example of a heat treatment apparatus of the present invention. In FIG. 1, a metal wire 1 wound around a plurality of coils (not shown) is continuously drawn out from each coil in parallel and enters a polishing machine 2. Then, the wire drawing lubricant applied to the surface of the metal wire in the preceding wire drawing step is peeled off, and then the fine wire drawing lubricant that could not be removed by the polishing machine 2 is wiped off by the wiping machine 3. Subsequently, each metal wire 1 passes through a heating furnace 4 in which a plurality of pipes are juxtaposed in parallel (not shown), and then cooled through a cooling device 5 to obtain heat treatment for obtaining predetermined characteristics. After being wound, it is wound around each coil again. Here, the inside of the pipe through which the metal wire inside the heating furnace 4 and the cooling device 5 is passed is maintained in a non-oxidizing atmosphere, and the surface oxidation of the metal wire 1 is suppressed.
The metal wire heat treatment apparatus of the present invention can greatly improve productivity by simultaneously heat-treating a plurality of metal wires in parallel.
本発明は、図１に示すように、加熱炉４と冷却装置５で熱処理する前に、金属線材１の表面を研磨する研磨機２を設置することで、短時間で金属線材１の表面に塊や薄い膜で付着している伸線潤滑剤を浮かせ、容易に引き剥がすことができる。そして、研磨機２の後段に配置する拭取り機３で金属線材１の表面を拭取ることにより、引き剥がした伸線潤滑剤の残り滓や研磨粉を完全に除去することができる。これにより、本発明の熱処理装置は、伸線潤滑剤の加熱炉内への持ち込みを効果的に抑制し、金属線材の表面疵を防止できる。 In the present invention, as shown in FIG. 1, before the heat treatment in the heating furnace 4 and the cooling device 5, the polishing machine 2 for polishing the surface of the metal wire 1 is installed, so that the surface of the metal wire 1 can be obtained in a short time. The wire drawing lubricant adhering to a lump or thin film can be floated and easily peeled off. Then, by wiping the surface of the metal wire 1 with the wiping machine 3 arranged at the subsequent stage of the polishing machine 2, the remaining wrinkles and polishing powder of the drawn wire drawing lubricant can be completely removed. As a result, the heat treatment apparatus of the present invention can effectively suppress the drawing lubricant from being brought into the heating furnace and prevent surface defects of the metal wire.
本発明で適用できる金属線材の表面を研磨する研磨機の一例を模式的に図３に示す。本発明の研磨機２は、例えば図３に示すように、複数（例えば６本）の金属線材１を並列で同時に通線させながら、並列した金属線材１の上下に、駆動可能な回転軸を有する円筒体７の研磨ブラシを千鳥状に配置する。そして、それぞれの金属線材１の表面に、円筒体７の周面相当部を構成する研磨ブラシを接触させながら通線して擦過することで研磨でき、金属線材１の表面に付着している伸線潤滑剤を容易に引き剥がすことができる。このとき、研磨ブラシの材質は、金属やプラスチック等が適用できる。
また、本発明で適用する研磨機は、ブラシの代わりに砥石を用いることができる。また、研磨機２は、研磨布等で金属線材１を挟み込んで研磨する構造のものであってもよい。
研磨機２としては、図３に示すように、円筒体７を用いることが好ましい。その理由は、円筒体７を回転させることにより、並列した金属線材１の表面に研磨力を付与することができる。円筒体７としては、研磨ブラシの他に、砥石を用いることができる。
本発明の研磨機の好ましい形態としては、金属線材１よりも柔らかい材質であるナイロン毛のブラシを使用することで、金属線材１の表面に疵を付けずに研磨することができる。このとき、円筒体７の研磨ブラシを金属線材１の通線方向と同方向または反対方向に回転させて、金属線材１の通線速度と相対速度差を持たせて金属線材１の表面を研磨することにより、金属線材１の表面に塊状や薄い膜となって固着した伸線潤滑剤を容易に引き剥がすことができる。
また、本発明の研磨機のより好ましい形態としては、複数（例えば３本）の円筒体７の研磨ブラシを回転させながら、それぞれの位相を替えて回転軸方向に揺動させることにより、金属線材１の上下面だけでなく、幅方向にも研磨力を加えることができ、金属線材１の表面全周を清浄にすることが可能となる。
An example of a polishing machine for polishing the surface of a metal wire applicable in the present invention is schematically shown in FIG. For example, as shown in FIG. 3, the polishing machine 2 of the present invention has drive shafts that can be driven above and below the parallel metal wires 1 while simultaneously passing a plurality of (for example, 6) metal wires 1 in parallel. The polishing brushes of the cylindrical body 7 are arranged in a staggered manner. Then, the surface of each metal wire 1 can be polished by passing through and rubbing while a polishing brush constituting the peripheral surface of the cylindrical body 7 is in contact with the surface of the metal wire 1. The wire lubricant can be easily peeled off. At this time, the material of the polishing brush can be metal, plastic, or the like.
Moreover, the grinder applied by this invention can use a grindstone instead of a brush. Further, the polishing machine 2 may have a structure in which the metal wire 1 is sandwiched and polished by a polishing cloth or the like.
As the polishing machine 2, it is preferable to use a cylindrical body 7 as shown in FIG. The reason is that the polishing force can be applied to the surfaces of the parallel metal wires 1 by rotating the cylindrical body 7. As the cylindrical body 7, a grindstone can be used in addition to the polishing brush.
As a preferred embodiment of the polishing machine of the present invention, by using a nylon bristle brush which is softer than the metal wire 1, the surface of the metal wire 1 can be polished without wrinkles. At this time, the surface of the metal wire 1 is polished by rotating the polishing brush of the cylindrical body 7 in the same direction as that of the metal wire 1 or in the opposite direction to give a difference in relative speed between the metal wire 1 and the wire. By doing so, the wire-drawing lubricant adhered to the surface of the metal wire 1 as a lump or thin film can be easily peeled off.
Further, as a more preferable form of the polishing machine of the present invention, a metal wire is obtained by changing the phase of each of the polishing brushes of a plurality of (for example, three) cylindrical bodies 7 and swinging them in the direction of the rotation axis. The polishing force can be applied not only to the upper and lower surfaces of 1 but also in the width direction, and the entire surface of the metal wire 1 can be cleaned.
本発明の金属線材の熱処理装置は、金属線材の表面を研磨するだけでは、金属線材の表面から引き剥がした伸線潤滑剤の滓や研磨粉が金属線材の表面に再付着することがあるから、研磨機の後段に金属線材の表面を拭取る拭取り機を配置する。
本発明で適用できる金属線材の表面を拭取る拭取り機の一例を模式的に図４に示す。図４に示すように、本発明の拭取り機３は、複数（例えば６本）の金属線材１を並列で同時に通線させながら、それぞれの金属線材１の上下面および／または左右面に拭取り布８ａまたは紙８ａを固定治具８ｂで挟持する。そして、金属線材１の表面に拭取り布８ａまたは紙８ａを押し当て、押圧しながら金属線材１を通線することで、再付着した伸線潤滑剤の滓や研磨粉を拭取ることができる。なお、拭取り布８ａまたは紙８ａと固定治具８ｂは、金属線材１を通線したときに、金属線材１とともに移動してしまうのを防ぐために、スリット９で固定することが好ましい。
また、拭取り機３の後段にエアーワイパー（図示しない）を設置することがより好ましく、これにより拭取り布で除去しきれなかった伸線潤滑剤の滓や研磨粉をより確実に除去することができる。
In the heat treatment apparatus for metal wire of the present invention, only by polishing the surface of the metal wire, wrinkles or polishing powder of the wire drawing lubricant peeled off from the surface of the metal wire may reattach to the surface of the metal wire. A wiping machine for wiping the surface of the metal wire rod is disposed after the polishing machine.
An example of a wiping machine for wiping the surface of the metal wire applicable in the present invention is schematically shown in FIG. As shown in FIG. 4, the wiping machine 3 of the present invention wipes a plurality of (for example, six) metal wires 1 in parallel on the upper and lower surfaces and / or left and right surfaces of each metal wire 1. The take-up cloth 8a or the paper 8a is clamped by the fixing jig 8b. Then, the wiping cloth 8a or the paper 8a is pressed against the surface of the metal wire 1, and the metal wire 1 is passed through while being pressed, so that the wrinkles and polishing powder of the reattached wire drawing lubricant can be wiped off. . The wiping cloth 8a or paper 8a and the fixing jig 8b are preferably fixed by the slit 9 in order to prevent the wiping cloth 8a or the paper 8a and the fixing jig 8b from moving together with the metal wire 1.
Moreover, it is more preferable to install an air wiper (not shown) in the subsequent stage of the wiping machine 3, thereby more reliably removing the wire lubricant lubricant and polishing powder that could not be removed by the wiping cloth. Can do.
上記で説明したように、本発明の金属線材の熱処理装置は、加熱炉に金属線材を挿入する前に予め金属線材の表面を研磨する研磨機と、金属線材の表面を拭取る拭取り機とを順に配置することで、金属線材表面に付着している伸線潤滑剤の滓や研磨粉を容易に除去することができる。
本発明の金属線材の熱処理装置は、より細かな伸線潤滑剤の滓や研磨粉を完全に除去するために、図２に示す研磨機２と拭取り機３の間に、溶媒により金属線材１の表面を洗浄する洗浄機６を配置することが好ましい。
溶媒としては、溶剤以外に水、温水（典型的には３０℃以上）を用いることができ、伸線潤滑剤の成分に応じて適宜選択できる。中でも、酸性水（典型的にはｐＨ５以下）は、例えばステアリン酸カルシウム等の金属石鹸系を主成分とする伸線潤滑剤を金属線材表面から落としやすいという性質を有する。したがって、金属線材の表面にステアリン酸カルシウム等の金属石鹸系を主成分とする伸線潤滑剤が付着している場合は、溶媒として酸性水を用いることが好ましい。このとき、金属線材表面の付着物の組成に応じてｐＨを適宜選択することができる。
ここで、伸線工程を経た金属線材の表面を走査型電子顕微鏡で観察した結果の一例を図６（ａ）に示す。伸線工程を経た金属線材の表面は、濃灰色で示されるステアリン酸カルシウムを主成分とする伸線潤滑剤が全長に亘って付着している。この金属線材を、図３に示す研磨機２で研磨を行ない、次いで図５に示す洗浄機６で、溶媒としてｐＨ３の酸性水を３０℃で用いて、溶媒に後述する超音波振動を印加して金属線材の表面を洗浄すると、図６（ｂ）に示すように、図６（ａ）にあった濃灰色で示される伸線潤滑剤が除去されたことがわかる。
As described above, the metal wire heat treatment apparatus of the present invention includes a polishing machine that polishes the surface of the metal wire in advance before inserting the metal wire into the heating furnace, and a wiping machine that wipes the surface of the metal wire. By arranging these in order, wrinkles and polishing powder of the wire drawing lubricant adhering to the surface of the metal wire can be easily removed.
The metal wire heat treatment apparatus of the present invention uses a solvent between the polishing machine 2 and the wiping machine 3 shown in FIG. 2 with a solvent to completely remove finer wrinkles and polishing powder of the wire drawing lubricant. It is preferable to arrange a washing machine 6 for washing the surface of 1.
As the solvent, water and warm water (typically 30 ° C. or more) can be used in addition to the solvent, and can be appropriately selected according to the components of the wire drawing lubricant. Among them, acidic water (typically pH 5 or lower) has a property that it is easy to drop a wire drawing lubricant mainly composed of a metal soap such as calcium stearate from the surface of the metal wire. Accordingly, when a wire drawing lubricant mainly composed of a metal soap such as calcium stearate is attached to the surface of the metal wire, it is preferable to use acidic water as a solvent. At this time, the pH can be appropriately selected according to the composition of the deposit on the surface of the metal wire.
Here, an example of the result of observing the surface of the metal wire rod that has undergone the wire drawing step with a scanning electron microscope is shown in FIG. On the surface of the metal wire that has undergone the wire drawing step, a wire drawing lubricant mainly composed of calcium stearate shown in dark gray is attached over the entire length. The metal wire is polished by the polishing machine 2 shown in FIG. 3, and then the cleaning machine 6 shown in FIG. 5 is used with acidic water having a pH of 3 as a solvent at 30 ° C. When the surface of the metal wire was washed, it was found that the wire drawing lubricant shown in dark gray in FIG. 6A was removed as shown in FIG. 6B.
また、溶媒としての温水は、人体への影響が少なく、供給ならびに廃棄といった取扱いが容易である。そして、温水は、例えばステアリン酸ナトリウム等の石鹸系を主成分とする伸線潤滑剤を溶かしやすいという性質を有する。したがって、金属線材の表面にステアリン酸ナトリウム等の石鹸系を主成分とする伸線潤滑剤が付着している場合は、溶媒として温水を用いることが好ましい。 Moreover, warm water as a solvent has little influence on the human body and is easy to handle such as supply and disposal. And warm water has the property that it is easy to melt | dissolve the wire-drawing lubricant which has soap systems, such as sodium stearate, as a main component. Therefore, when a wire drawing lubricant mainly composed of soap such as sodium stearate adheres to the surface of the metal wire, it is preferable to use warm water as a solvent.
本発明の金属線材の熱処理装置で適用できる洗浄機の一例を図５に示す。洗浄機６は、例えば図５に示すような、洗浄タンク１１内に溶媒を浸し、溶媒内に複数（例えば６本）の金属線材１を並列で同時に通過させることで金属線材１の表面の伸線潤滑剤等を除去する装置が好適である。
図５に示す洗浄機６は、洗浄タンク１１の前面と背面の一部に金属線材１が通過するためのスリット９を設けている。洗浄タンク１１のスリット９の隙間から流れ出た溶媒は、戻り配管１４を通り、リザーブタンク１２に溜まり、ポンプ１３によって再び洗浄タンク１１に戻る構造となっている。ここで、本発明で適用する洗浄機としては、洗浄タンク１１を通過した金属線材１の表面に溶媒をシャワー状に散水することが好ましい。これにより、本発明は、金属線材１の表面の伸線潤滑剤の滓や研磨粉を効果的に除去することもできる。
また、洗浄効果を促進させる補助機構として、洗浄タンク１１内の底面には、超音波振動子１０を設置し、溶媒に超音波振動を印加できるようにしておくことが好ましい。本発明で適用する洗浄機は、溶媒を振動させることで洗浄効果をより高めることができる。
また、図５に示す洗浄機６の入口および出口には、図４に示す拭取り機３をそれぞれ配置し、金属線材表面に付着している伸線潤滑剤の滓、研磨粉や溶媒を拭取ることがより好ましい。
FIG. 5 shows an example of a washing machine that can be applied to the metal wire heat treatment apparatus of the present invention. For example, as shown in FIG. 5, the cleaning machine 6 immerses a solvent in a cleaning tank 11 and simultaneously passes a plurality of (for example, six) metal wires 1 in parallel in the solvent to extend the surface of the metal wire 1. An apparatus for removing the wire lubricant and the like is suitable.
The cleaning machine 6 shown in FIG. 5 is provided with slits 9 for allowing the metal wire 1 to pass through a part of the front surface and the back surface of the cleaning tank 11. The solvent that flows out from the gap of the slit 9 of the cleaning tank 11 passes through the return pipe 14, accumulates in the reserve tank 12, and returns to the cleaning tank 11 again by the pump 13. Here, as a washing machine applied by this invention, it is preferable to spray a solvent on the surface of the metal wire 1 which passed the washing tank 11 in the shape of a shower. Thereby, this invention can also remove effectively the wrinkles and polishing powder of the wire drawing lubricant on the surface of the metal wire 1.
Further, as an auxiliary mechanism for promoting the cleaning effect, it is preferable that an ultrasonic vibrator 10 is installed on the bottom surface in the cleaning tank 11 so that ultrasonic vibration can be applied to the solvent. The washing machine applied in the present invention can further enhance the washing effect by vibrating the solvent.
Moreover, the wiping machine 3 shown in FIG. 4 is arranged at the inlet and the outlet of the cleaning machine 6 shown in FIG. 5, respectively, so that the wire lubricant lubricant adhering to the surface of the metal wire, polishing powder and solvent are wiped off. It is more preferable to take.
