Description

この発明は水密圧縮成形撚り導体の製造方法およびその装置に関する。   The present invention relates to a method for manufacturing a watertight compression molded twisted conductor and an apparatus therefor.

水密絶縁電線を構成する水密圧縮成形撚り導体の製造に関する先行技術として特許文献１がある。   There exists patent document 1 as a prior art regarding manufacture of the watertight compression molding twisted conductor which comprises a watertight insulated wire.

特開平７−２８８０５１号公報（特許請求の範囲の請求項１）JP-A-7-288051 (claim 1)

上記特許文献１の技術は、「撚線導体に水密コンパウンドを注入し、圧縮ダイスにより圧縮し内層圧縮導体とし、前記内層圧縮導体に水密コンパウンドを注入して軽圧縮ダイスにより軽圧縮すると共に、前記軽圧縮ダイスの回転速度と、前記内層圧縮導体の前記軽圧縮ダイスへの挿通速度とを別個に制御させる」ものである。   The technology of Patent Document 1 described above is: “Injecting a watertight compound into a stranded conductor, compressing with a compression die to form an inner layer compression conductor, injecting a watertight compound into the inner layer compression conductor, and lightly compressing with a light compression die, The rotational speed of the light compression die and the insertion speed of the inner layer compression conductor into the light compression die are separately controlled. "

また、水密圧縮撚り導体の一般的な製造技術としては、「中心素線に水密コンパウンドを塗布し、この中心素線の上に、水密コンパウンドを塗布した第一層の素線を撚り合わせて圧縮成形し、さらにその上に水密コンパウンドを塗布し、その上に第二層の素線を撚り合わせて圧縮ダイスで圧縮成形する」ものがある。   Also, the general manufacturing technology for watertight compression stranded conductors is as follows: “Watertight compound is applied to the center wire, and the first layer wire coated with watertight compound is twisted on this center wire and compressed. There is a type of molding, further applying a watertight compound thereon, twisting the strands of the second layer thereon and compression molding with a compression die.

上記先行技術において前者は、軽圧縮ダイスを回転させる必要があり、かつ、軽圧縮ダイスの回転と内層圧縮導体の挿通速度を別個に制御する必要があって、機械系、制御系の構造が複雑になり装置全体がコスト高とならざるを得ない。   In the above prior art, the former needs to rotate the light compression die, and it is necessary to separately control the rotation of the light compression die and the insertion speed of the inner layer compression conductor, and the structure of the mechanical system and the control system is complicated. Therefore, the entire apparatus has to be expensive.

また、特許請求の範囲では「水密コンパウンドを注入し」となっているが、図面から解釈すると、撚り素線あるいは圧縮導体に向けて水密コンパウンドを「滴下」するもので、このために水密コンパウンドを過不足なく均等に塗布できず、軽圧縮ダイスを回転させることとなっているが、軽圧縮ダイスを回転させたとしても満足できる均等塗布ができず、なによりも、水密コンパウンドが要所外に漏出落下して装置周辺を汚し作業環境を低下させる問題がある。   Further, in the claims, “watertight compound is injected”, but when interpreted from the drawing, the watertight compound is “dripped” toward the stranded wire or the compressed conductor. Even if the light compression die is rotated, it is impossible to apply evenly without excess or deficiency, but even if the light compression die is rotated, satisfactory uniform application is not possible, and above all, the watertight compound is out of the main point. There is a problem that the work environment is deteriorated by leaking and dropping to contaminate the periphery of the apparatus.

また、後者では素線または圧縮撚り導体の表面に個別に水密コンパウンドを塗布せねばならず、多くの工程を必要となって製造コストが高くなる他、水密コンパウンドが要所以外に漏出落下して作業環境が悪化するなどの問題をもっている。   In the latter case, the watertight compound must be individually applied to the surface of the strands or the compressed stranded conductor, which requires many steps and increases the manufacturing cost. In addition, the watertight compound leaks and falls outside the main points. Has problems such as worsening work environment.

上記従来技術の問題に鑑みこの発明は、必要最小限に、かつ、より均一な水密混和物の充填・塗布を可能にし、装置全体のコストを低減し、水密混和物の充填・塗布の工数を少なくして水密圧縮撚り導体の製造コストを低減し、水密混和物の充填・塗布作業において、水密混和物が要所以外に漏出落下せず、作業環境が低下することのない水密圧縮撚り導体の製造技術を提供することを課題とする。   In view of the above-described problems of the prior art, the present invention enables filling and application of a water-tight mixture that is minimal and more uniform, reduces the cost of the entire apparatus, and reduces the number of man-hours for filling and applying a water-tight mixture. Reduces the manufacturing cost of watertight compression twisted conductors, and prevents the watertight mixture from leaking and dropping to other places in the filling and coating operations of watertight blends, so that the work environment does not deteriorate. It is an object to provide a manufacturing technique.

上記課題を解決するためにこの発明は、撚り素線間に水密混和物を充填し圧縮成形してなる水密圧縮撚り導体の製造方法において、中心導体に向けて撚り素線を収斂し、その周囲から上記中心導体と撚り素線に水密混和物を供給しながら撚り合わせて圧縮成形し、引き続いて、この圧縮撚り導体を水密混和物中に通して、その表面に水密混和物を塗布する工程を少なくとも一回通して水密圧縮撚り導体の芯を製作し、この芯の表面に最外層の撚り素線を撚り合わせて圧縮成形ダイスに引き通すことからなるものである。   In order to solve the above problems, the present invention provides a method for producing a watertight compression stranded conductor, in which a watertight mixture is filled between the strands and compression-molded. To the center conductor and the twisted strand while supplying the watertight mixture, and then compression-molding, and subsequently passing the compression-twisted conductor through the watertight mixture to apply the watertight mixture to the surface. The core of the watertight compression twisted conductor is manufactured at least once, and the outermost layer strand is twisted on the surface of the core and passed through the compression molding die.

また、ケージに装架されたボビンから繰り出された素線を収斂し圧縮ダイスに導入する撚り口ナットを含む偏心ホルダーと、前段で圧縮成形ダイス、後段で水密混和物を塗布する塗布量調整ダイスを備えたダイスホルダーとからなり、上記偏心ホルダーに水密混和物を注入する注入孔を設け、この注入孔から撚り口ナットと偏心ホルダーとの対向面間に形成される環状凹溝で開口する水密混和物の主流路を設け、かつ、上記主流路から流量調整バルブを介して上記塗布量調整ダイスを設けた中空軸孔に水密混和物を供給する分岐流路を設けてなり、上記撚り口ナットと偏心ホルダーとの対向面間に介在させるスペーサーにより上記環状凹溝での水密混和物の流量を調整し、上記流量調整バルブとして、上記中空軸孔に至る前の分岐流路にニードルバルブを設けてなる構成としたものである。   Also, an eccentric holder containing a twist nut that converges the wire drawn from the bobbin mounted on the cage and introduces it into the compression die, and a coating amount adjustment die that applies the compression molding die at the front stage and the watertight mixture at the rear stage. Provided with an injection hole for injecting a water-tight mixture into the eccentric holder, and a water-tight opening that is opened by an annular groove formed between the opposing surfaces of the twist nut and the eccentric holder from the injection hole. A branch channel for supplying a water-tight mixture from the main channel to a hollow shaft hole provided with the application amount adjusting die through a flow rate adjusting valve; The flow rate of the water-tight mixture in the annular groove is adjusted by a spacer interposed between the opposing surfaces of the eccentric holder and the knee as a flow rate adjusting valve in the branch channel before reaching the hollow shaft hole. It is obtained by the provided comprising configure Rubarubu.

上記の如く構成するこの発明によれば、先ず中心導体に向けて収斂された撚り素線の表面に流量制御された水密混和物が過不足なく均一に塗布されて圧縮成形され、引き続いて上記圧縮成形された撚線導体が水密混和物で満たされた中空軸孔と塗布量調整ダイスを通過する間に、その表面に所要量の水密混和物が過不足なく均等に塗布され、しかも、要所以外に漏出落下することがない。   According to the present invention configured as described above, first, the watertight mixture whose flow rate is controlled is uniformly applied to the surface of the stranded strands converged toward the center conductor without being deficient, and is compression-molded. While the formed stranded wire conductor passes through the hollow shaft hole filled with the water-tight mixture and the coating amount adjusting die, the required amount of the water-tight mixture is uniformly and evenly applied to the surface. There is no leakage and dropping.

また、最外層の撚り合わせと圧縮成形において、前段の「芯」表面に塗布された水密混和物が圧縮成形の際に撚り素線間に入り込み、最外層表面には水密混和物が殆ど存在しないので、絶縁被覆の際行われる導体・絶縁間の水密処理では、上記素線間に充填した水密混和物が存在しないので絶縁体の剥ぎ取りに支障を来たす心配がない。   In addition, in the twisting and compression molding of the outermost layer, the water-tight mixture applied to the “core” surface in the previous stage enters between the strands during compression molding, and there is almost no water-tight mixture on the outermost layer surface. Therefore, in the watertight treatment between the conductor and the insulation performed at the time of insulation coating, there is no fear that the insulation will be hindered because there is no watertight mixture filled between the wires.

先ず図２を参照しながら水密圧縮成形導体の製造工程を説明する。サプライに支持されたボビンＢ１から繰り出された中心素線Ｗ１の上にボビンＢ２を装架したケージＫ１から繰り出された第一層の素線Ｗ２が収斂され、第一の水密圧縮撚り導体製造装置１０ａを通過する間に、中心素線Ｗ１と第一層の素線Ｗ２に水密混和物が供給されながら撚り合わされ、圧縮成形され、その表面に水密混和物が塗布されて第一層目の水密圧縮撚り導体ＳＢ１となる。   First, the manufacturing process of the watertight compression molded conductor will be described with reference to FIG. The first layer of wire W2 drawn out from the cage K1 in which the bobbin B2 is mounted on the center wire W1 drawn out from the bobbin B1 supported by the supply is converged, and the first watertight compressed twisted conductor manufacturing apparatus While passing through 10a, the water-tight mixture is twisted while being supplied to the central wire W1 and the first-layer wire W2, and compression-molded. It becomes the compression twist conductor SB1.

次に、ボビンＢ３を装架したケージＫ２から繰り出された第二層の素線Ｗ３は、表面に水密混和物を塗布した圧縮撚り導体ＳＢ１の上に収斂され、圧縮成形ダイスＭＤを通過する間に、上記圧縮撚り導体ＳＢ１（図２（ｂ））の表面に塗布された水密混和物が第二層の素線Ｗ３の相互間に入り込みながら圧縮成形され、表面には水密混和物が殆ど付着していない水密圧縮撚り導体ＳＢ２（図２（ｂ））が得られる。   Next, the wire W3 of the second layer drawn out from the cage K2 on which the bobbin B3 is mounted is converged on the compression twisted conductor SB1 whose surface is coated with a watertight mixture and passes through the compression molding die MD. In addition, the watertight mixture applied to the surface of the compression twisted conductor SB1 (FIG. 2 (b)) is compressed while entering between the strands W3 of the second layer, and the watertight mixture is almost adhered to the surface. A watertight compression twisted conductor SB2 (FIG. 2 (b)) that has not been obtained is obtained.

上記のようにして得られた水密圧縮撚り導体ＳＢ２の表面には素線の間隙や第一層の表面に充填・塗布した水密混和物が殆どなく、絶縁被覆を押出し成形する際、絶縁層に対して相溶性のある水密混和物を塗布しながら公知の押出し成形法により絶縁層が押出し成形するので、接続や端末処理をするとき絶縁体とともに上記水密混和物が撚り導体からスムーズに除去される。   The surface of the watertight compression-twisted conductor SB2 obtained as described above has almost no gap between the strands or a watertight mixture filled / coated on the surface of the first layer, and when the insulating coating is extrusion molded, On the other hand, since the insulating layer is extruded by a known extrusion method while applying a compatible watertight mixture, the watertight mixture is smoothly removed from the twisted conductor together with the insulator when performing connection or terminal treatment. .

なお、上記実施形態では１９本（２層）撚りで説明したが、３７本（３層）撚りの場合は、上記圧縮成形ダイスＭＤに替えて図示しない第二の水密圧縮撚り導体製造装置を配置し、水密混和物を塗布した第二層の上に第三層の素線を収斂し圧縮成形ダイスに引き通して３７本（３層）撚りの水密圧縮撚り導体が得られる。   In the above embodiment, 19 (2 layers) twist is described. However, in the case of 37 (3 layers) twist, a second watertight compression twisted conductor manufacturing device (not shown) is arranged instead of the compression molding die MD. Then, the strands of the third layer are converged on the second layer coated with the watertight mixture and passed through a compression molding die to obtain a 37 (three layers) twisted watertight compression twisted conductor.

次に、水密圧縮撚り導体の製造装置について図１を参照しながら説明する。ダイスホルダー１１の前段には圧縮成形ダイス１２が嵌められ、後段には水密混和物を均一に塗布する塗布量調整ダイス１３が袋ナット１４により取り付けられ、ダイスホルダー１１の上流側前面には偏心ホルダー１５がボルト１６により偏心調整可能に取り付けられ、このとき圧縮成形ダイス１２も固定される。   Next, a watertight compression twisted conductor manufacturing apparatus will be described with reference to FIG. A compression molding die 12 is fitted in the front stage of the die holder 11, and an application amount adjusting die 13 for uniformly applying the watertight mixture is attached to the rear stage by a cap nut 14. An eccentric holder is mounted on the upstream front surface of the die holder 11. 15 is attached by a bolt 16 so that the eccentricity can be adjusted, and at this time, the compression molding die 12 is also fixed.

偏心ホルダー１５には水密混和物の注入孔１７が開口し、この注入孔１７には水密混和物を供給する図示しない押出機を接続するコネクター１８が設けられ、注入孔１７から偏心ホルダー１５の撚り口ナット１９との対向面に開口する主流路２０が形成され、偏心ホルダー１５の前面には水密混和物の流量を調整するスペーサー２１を介して撚り口ナット１９がねじ込まれ、中心素線と収斂された撚り素線に水密混和物を供給する環状凹溝２２が形成されている。   The eccentric holder 15 has an injection hole 17 for the water-tight mixture, and the injection hole 17 is provided with a connector 18 for connecting an extruder (not shown) for supplying the water-tight mixture, and the eccentric holder 15 is twisted from the injection hole 17. A main flow path 20 that opens to the surface facing the mouth nut 19 is formed, and a twist mouth nut 19 is screwed into the front surface of the eccentric holder 15 via a spacer 21 that adjusts the flow rate of the water-tight mixture, thereby converging with the central strand. An annular groove 22 is formed for supplying a watertight mixture to the stranded strands.

上記主流路２０からはダイスホルダー１１に向けて分岐流路２３が設けられ、途中ニードルバルブ２４を介してダイスホルダー１１の中空軸孔２５に通じ、水密混和物の塗布量調整ダイス１３に至る。なお、ダイスホルダー１１にはヒーターの挿入孔Ｈ、断熱保温層Ｉが設けられ、全体をフレームＦで支持している。   A branch flow path 23 is provided from the main flow path 20 toward the die holder 11 and leads to the hollow shaft hole 25 of the die holder 11 through the needle valve 24 and reaches the application amount adjusting dice 13 of the watertight mixture. The die holder 11 is provided with a heater insertion hole H and a heat insulation layer I, and the whole is supported by a frame F.

次に操作について説明する。ケージＫ１に装架されたボビンＢ２から繰り出された素線Ｗ２は、目板Ｙを経て撚り口ナット１９と偏心ホルダー１５のアプローチ部分で収斂され、ここで図示しない押出機から供給された水密混和物は主流路２０と環状凹溝２２を経て撚合わされる各素線（中心素線Ｗ１と第一層の素線Ｗ２）の周囲から供給され圧縮成形ダイス１２で圧縮成形される。   Next, the operation will be described. The wire W2 fed out from the bobbin B2 mounted on the cage K1 is converged at the approach portion of the twist nut 19 and the eccentric holder 15 through the plate Y, and here is water-tight mixing supplied from an extruder (not shown). The object is supplied from the periphery of each strand (the central strand W1 and the first-layer strand W2) twisted through the main flow path 20 and the annular concave groove 22, and is compression-molded by the compression-molding die 12.

圧縮成形された撚り導体は、水密混和物で満たされた中空軸孔２５を通過し、後段で袋ナット１４により取り付けられた塗布量調整ダイス１３を経て必要最小限の水密混和物が塗布される。なお、中空軸孔２５への水密混和物の供給は、主流路２０から分岐流路２３を経て、途中ニードルバルブ２４により消費される水密混和物の量とバランスするようになっている。   The compression-formed twisted conductor passes through the hollow shaft hole 25 filled with the watertight mixture, and the minimum necessary watertight mixture is applied through a coating amount adjusting die 13 attached by a cap nut 14 at a later stage. . The supply of the water-tight mixture to the hollow shaft hole 25 is balanced with the amount of the water-tight mixture consumed by the needle valve 24 on the way from the main channel 20 through the branch channel 23.

以上説明したようにこの装置によれば、中心導体と収斂された撚り素線に対して、その周囲から水密混和物が過不足なく均等に供給されて撚り合わされるとともに圧縮成形され、圧縮成形された撚り導体は、適量供給（補給）される水密混和物で満たされた中空軸孔を通過し、塗布量調整ダイスを通過する間に所定量の水密混和物が過不足なく均等に塗布され、さらに中空軸孔に消費量とバランスするように水密混和物を補給するので、要所以外に水密混和物が漏出落下することがなく、作業環境の低下を招くことがない。   As described above, according to this apparatus, the watertight mixture is uniformly supplied from the periphery to the twisted strands converged with the center conductor, twisted together and compressed, molded and compressed. The twisted conductor passes through a hollow shaft hole filled with a watertight mixture to be supplied (supplied) in an appropriate amount, and a predetermined amount of the watertight mixture is evenly applied without passing through the coating amount adjusting die, Further, since the water-tight mixture is replenished to the hollow shaft hole so as to balance the consumption, the water-tight mixture does not leak out and drop in areas other than the main points, and the work environment is not lowered.

以上説明した如くこの発明は、装置全体の構造をシンプルにし、圧縮成形撚り導体への水密混和物の充填が過不足なく均等におこなえるようになり、さらに、要所以外に水密混和物が漏出落下することがなく、作業環境を改善するとともに製造コストを低減したもので産業上の利用価値は極めて高いものである。   As described above, the present invention simplifies the structure of the entire apparatus, and the compression-molded twisted conductor can be uniformly filled with the water-tight mixture without excess or deficiency. The industrial use value is extremely high because the manufacturing environment is reduced while the working environment is improved.
