通システムなどに使用される剛体電車線の製造方
法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method of manufacturing a rigid overhead contact line mainly used for subways, monorails, new transportation systems, etc.
最近、剛体電車線として、導電性が良く、耐食
性に富み、しかも比較的重量の軽い金属（例えば
アルミニウムまたはその合金）で剛体兼フイダー

（例えばステンレス）板を密着結合させたものが

Recently, as rigid overhead contact lines, the rigid body/feeder is made of a metal with good conductivity, high corrosion resistance, and relatively light weight (e.g. aluminum or its alloy), and the surface that comes in contact with the pantographs of electric trains etc. A structure in which metal (eg, stainless steel) plates with good wear and corrosion resistance are closely bonded has been developed. FIG. 4 shows an example of this, in which numeral 1 is a rigid body/feeder made of metal with good conductivity, and 2 is a metal plate with good abrasion resistance tightly connected to the head of the feeder.
このような剛体電車線においては、剛体兼フイ
ダー１と金属板２の接合部Ａに隙間があると、
各々の金属が有する電位の差により電気化学的腐
食が発生するので、両者の接合部Ａは金属的に完
全に密着させることが必要である。 In such a rigid overhead contact line, if there is a gap at the joint A between the rigid feeder 1 and the metal plate 2,
Since electrochemical corrosion occurs due to the difference in potential between the two metals, it is necessary that the joint A between the two be brought into complete metallic contact.
このため上記のような剛体電車線を製造する方
法としては、上記２種類の金属を高温、高圧下で
同時に押し出して両者の接合部を金属的に完全に
密着させる押出法が有効であるが、両金属は強
度、軟化温度等にかなりの差があり、押出機内で
の流動性も異なるため、第４図に示すうように剛

に押し出すことが不可能であり、結局第５図に示
すように、２枚の金属板２，２を内包する形で２
つの剛体兼フイダー１，１を対称配置で押し出し
たのち、これを２つの剛体電車線に分割するとい
う方法がとられている。なお、このような方法で
３つ又は４つの剛体電車線を同時に製造すること
も可能である。 For this reason, an effective method for manufacturing the above-mentioned rigid overhead contact line is the extrusion method, in which the two types of metals are extruded simultaneously under high temperature and high pressure, and the joints between the two are completely bonded metallically. Since the two metals have considerable differences in strength, softening temperature, etc., and their fluidity within the extruder is also different, it is necessary to extrude them into a form that has a metal plate 2 on only one side of a rigid body/feeder 1, as shown in Fig. 4. However, as shown in FIG.
The method used is to extrude two rigid bodies/feeders 1, 1 in a symmetrical arrangement and then divide them into two rigid overhead contact lines. Note that it is also possible to manufacture three or four rigid overhead contact lines at the same time using such a method.
しかし上記のような方法では、複数の剛体電車
線を同時に押出成形しなければならないため、押
出機のダイスの口径が単体を押し出す場合の２倍
以上となり、きわめて大型の押出機を必要とする
ことから、設備費がかさみ、コスト高になる欠点
がある。 However, in the above method, multiple rigid contact wires must be extruded at the same time, so the diameter of the die of the extruder is more than twice that of extruding a single piece, requiring an extremely large extruder. Therefore, it has the drawback of increasing equipment costs and increasing costs.

である。[Means for solving the problems and their effects] In order to solve the problems of the prior art as described above, the present invention comprises a rigid body/feeder made of metal with good conductivity and corrosion resistance, and In a method for manufacturing a rigid overhead contact line in which a metal plate with good wear resistance is tightly bonded to a metal plate, the metal with good conductivity and corrosion resistance is closely extruded together with the metal plate to form a head, and separately from this, , a body portion is formed of the metal with good conductivity and corrosion resistance, and has a groove taper for welding connection at the portion in contact with the head portion, and then the head portion and the body portion are welded and connected in the longitudinal direction. It is characterized by being integrated.
このようにすると密着押出は頭部だけでよいの
で、ダイスの口径が小さくて済み、小型の押出機

1 to 3 show one embodiment of the present invention. First, as shown in Figure 2, two metal plates 2, 2 with excellent wear resistance are enclosed, and a metal 3, 3 with good conductivity and corrosion resistance, such as aluminum or its alloy, is placed on both sides. Extrusion forms two heads 4, 4, which are divided. Separately, as shown in Figure 3, the same metal with good conductivity and corrosion resistance as above was extruded to form an almost inverted T.
A letter-shaped main body portion 5 is formed. Groove tapers 6, 6 are formed at the top of the main body portion 5 for welding connection. Next, as shown in FIG.
The top of the head 4 is placed on the bottom surface of the head 4, and the two are welded and connected in the longitudinal direction to be integrated, thereby obtaining a rigid overhead contact wire 7. 8 and 8 are the welded parts. The single length of the rigid overhead contact line 7 is usually about 10 m.

As explained above, according to the present invention, the head and body parts of the rigid overhead contact line are manufactured separately and then welded and connected to obtain the rigid overhead contact line, which has good conductivity and corrosion resistance. Close contact extrusion of metal and metal with good wear resistance is performed only at the head, so the die for extrusion only needs to have a small diameter, and a large extruder is not required, making it possible to produce rigid contact wires at low cost. It has the advantage of being manufacturable.
