［産業上の利用分野］
本発明は複合線材、特に銅被覆アルミ線に好適する複合
線材の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for manufacturing a composite wire, particularly a composite wire suitable for copper-coated aluminum wire.
［従来の技術］
従来よりＣｕ被覆ＡＩ線材を製造する方法として静水圧
押出加工によるものが知られている。[Prior Art] Hydrostatic extrusion has been known as a method for producing Cu-coated AI wires.
この方法は、第２図に示すようにＣｕ管１の内部にＡｌ
ロッド２を充填し、その両端部分を先端部材３および後
端部材４とにより密封した後、Ｃｕ管１と先端部材３お
よび後端部材４とをエレクトロンビーム法により溶接し
て押出ビレット５を製作し、次いでこのビレットに静水
圧押出加工および伸線加工を施してＣｕ被覆ＡＩ線を製
造するものである。In this method, Al is placed inside the Cu tube 1 as shown in FIG.
After filling the rod 2 and sealing both ends thereof with the tip member 3 and the rear end member 4, the Cu tube 1 and the tip member 3 and the rear end member 4 are welded by the electron beam method to produce an extruded billet 5. Then, this billet is subjected to hydrostatic extrusion processing and wire drawing processing to produce a Cu-coated AI wire.
上記のようなビレットの先端部材の材質はその押出圧力
がビレットの本体部分の押出圧力より低くなるように、
一方、後端部材の材質は本体部分の押出圧力より高くな
るように選定される。The material of the tip of the billet as described above is selected so that its extrusion pressure is lower than the extrusion pressure of the main body of the billet.
On the other hand, the material of the rear end member is selected so that the extrusion pressure is higher than that of the main body portion.
しかしながら、たとえばＡｌロッドとして高純度Ａ１を
用いた場合、ビレット本体部分の平均硬度（ビレブトの
軸方向に垂直な断面における各素材の硬度をその面積比
において配分した値の平均値−断面積が同一である部分
では押出圧力に近似される。）はＨｖ３２程度と非常に
小さくなるため、先端部材の材質をその硬度がこれより
小さく、かつＣｕ管との溶接性に優れたものに選定する
ことは非常に困難である。However, for example, when high-purity A1 is used as the Al rod, the average hardness of the billet body (the average value of the hardness of each material in the cross section perpendicular to the axial direction of the billet divided by the area ratio - the cross-sectional area is the same) (approximate to the extrusion pressure in some parts) is very small, around Hv32, so it is difficult to select a material for the tip member that has a hardness smaller than this and has excellent weldability with the Cu tube. Very difficult.
［発明が解決しようとする課題］
本発明は上記の難点を解消するためになされたもので、
金属管内に軟質材料からなる金属ロッドを収容したビレ
ットの押出初期の圧力を低下せしめ、押出中の圧力変化
、特に押出初期の圧力上昇をスムーズにすることにより
複合線材を容易に製造することができる方法を提供する
ことをその目的とする。[Problem to be solved by the invention] The present invention has been made in order to solve the above-mentioned difficulties.
By lowering the pressure at the initial stage of extrusion of a billet containing a metal rod made of a soft material in a metal tube, and smoothing the pressure change during extrusion, especially the pressure increase at the beginning of extrusion, it is possible to easily manufacture a composite wire rod. Its purpose is to provide a method.
［課題を解決するための手段］
本発明は、金属管内にこれより軟質の材料からなる金属
ロッドを収容し、前記金属管の両端部を先端側がテーパ
状に成形された先端部材および後端部材とにより密封し
た後、これを押出すことにより複合線材を製造する方法
において、前記先端部材の内部を中空に形成し、この内
部に前記金属ロッドの先端部を嵌合せしめたことを特徴
とする。[Means for Solving the Problems] The present invention provides a tip member and a rear end member in which a metal rod made of a softer material is accommodated in a metal tube, and both ends of the metal tube are formed into a tapered shape on the tip side. In the method of manufacturing a composite wire by sealing with and then extruding, the interior of the tip member is formed hollow, and the tip of the metal rod is fitted into this interior. .
本発明の方法は、金属管内部に充填される金属ロッドの
硬度値が小さいほど有効である。この理由はビレットの
本体部分の平均硬度より低い硬度を有する先端部材を材
質的に選定するものが一般的に非常に困難なことによる
。金属管の材質としてはＣｕ、 Ｃｕ系合金、Ｆｅ５Ｆ
ｅ系合金等が、一方、金属ロッドとしてはＡＩ、高純度
Ａ１等を挙げることができる。The method of the present invention is more effective as the hardness value of the metal rod filled inside the metal tube is smaller. The reason for this is that it is generally very difficult to select a material for the tip member that has a hardness lower than the average hardness of the main body of the billet. The material of the metal tube is Cu, Cu alloy, Fe5F.
Examples of the metal rod include e-based alloy and the like, while examples of the metal rod include AI, high-purity A1, and the like.
［作用］
本発明においては、先端側がテーパ状に成形された先端
部材の内部が中空に形成され、この内部にも軟質材料か

ち、先端部材と金属管の肉厚をほぼ同一とすれば、先端
部分の平均硬度は若干増大するが、断面積が小さいため
押出圧力は本体部分より低下する。[Function] In the present invention, the interior of the tip member whose tip side is formed into a tapered shape is formed hollow, and the tip of the metal rod made of a soft material is fitted inside this, so that, for example, the tip member can be made of the same material as the metal tube, and the extrusion pressure can be gradually increased. That is, if the wall thickness of the tip member and the metal tube are approximately the same, the average hardness of the tip portion will increase slightly, but the extrusion pressure will be lower than that of the main portion because the cross-sectional area is small.
［実施例］ 以下本発明の一実施例について説明する。[Example] An embodiment of the present invention will be described below.

中空である。First, a metal tube 9 having an outer diameter of 100 mm and an inner diameter of 9 mm, a tip member 7 and a rear end member 8 were manufactured. This tip member 7
consists of a cylindrical nose portion with an outer diameter of 36 mm and a truncated conical tapered portion with a length of 88.8 m continuing from this base to the metal tube 9, and the angle of this taper portion is approximately 47″. The inside is hollow.

At this time, since the inside of the metal tube is maintained in a vacuum, it is possible to prevent interference between the metal tube and the rod during extrusion.

A u-coated AI wire was manufactured. In this case, since the average hardness of the conical portion was lower than the average hardness of the main body portion, stable extrusion could be performed.
