に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing an aluminum-stainless steel composite contact wire, and is particularly suitable for manufacturing an aluminum-stainless steel composite contact wire whose stainless steel surface serving as a sliding surface has a predetermined shape. It relates to a manufacturing method.
摺動面となるステンレス鋼面に丸味を有するア
ルミニウム−ステンレス鋼トロリ線を圧延圧接方
式で製造する場合、従来、溝底部に丸味をつけた
溝を有する溝付ロールに導入するステンレス鋼を
上記丸底形状に合つた形状に予備成形したものと
していた。 When manufacturing an aluminum-stainless steel contact wire with a rounded stainless steel surface that serves as a sliding surface using a rolling pressure welding method, conventionally, the stainless steel introduced into a grooved roll having a rounded groove at the bottom of the groove is It was preformed into a shape that matched the bottom shape.
そのため、ステンレス鋼を丸底形状に別工程ま
たはライン上で成形する必要があつた。 Therefore, it was necessary to mold stainless steel into a round bottom shape in a separate process or on a line.
ところで、別工程で成形するようにすると、丸
味のある帯状のものとなるため、巻取りが困難に
なる。 By the way, if it is formed in a separate process, it will become a rounded band-like product, making it difficult to wind it up.
また、別に成形治具が必要となり、不経済であ
る。そして成形時に潤滑剤を使用したり、あるい
はごみの付着があつたりすると、後処理が必要と
なり、それに時間を要する。 Furthermore, a separate forming jig is required, which is uneconomical. If a lubricant is used during molding or if dust is attached, post-treatment is required, which takes time.
また、ワイヤブラツシング時に丸味があるた
め、ブラシが引つかかり危険であり、工程上のガ
イド等の構造が丸味に合つたものとしなければな
らないので複雑となり、高価なものとなる。 In addition, the roundness during wire brushing poses a risk of the brush getting caught, and the structure of guides and the like in the process must match the roundness, making it complicated and expensive.
また、ライン上で成形するようにすると、成形
を清浄、ワイヤブラツシング前に行う必要があ

があり、それ以外にライン上に成形工程を入れる
ため、工程が長くなるという欠点を生ずる。 In addition, when forming on the line, it is necessary to clean the forming and perform it before wire brushing, and there are similar problems except for the above-mentioned difficulty in winding. This has the disadvantage that the process becomes longer.
本発明は上記に鑑みてなされたもので、その目

した点にある。 A feature of the present invention is that one of the rolls is a grooved roll in which a long thin stainless steel plate and a thick aluminum plate, each of which has a cleaned surface, are stacked on top of each other, and an endless groove with a groove bottom of a predetermined shape is provided on the peripheral end surface. The aluminum plate is fed to a pressure welding device consisting of a pair of upper and lower rolls, and the pair of rolls forms the stainless thin plate into a predetermined shape.
It is plastically deformed at a rolling reduction rate of 80% and pressed against the thin stainless steel plate formed into the above-mentioned predetermined shape to produce an aluminum-stainless steel composite contact wire whose stainless steel surface that becomes the sliding surface has a predetermined shape. That's what I did.
