産業上の利用分野
この発明は、銅−クロム系合金からなり、かつ
耐軟化性に優れた製品を得るための製造方法に関
し、特に、たとえば抵抗溶接器に用いられる電極
チツプを製造するための方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a manufacturing method for obtaining a product made of a copper-chromium alloy and having excellent softening resistance, and particularly relates to an electrode used in a resistance welder, for example. The present invention relates to a method for manufacturing chips.
従来の技術
たとえば、抵抗溶接器に用いられる電極チツプ

作られてきた。Conventional technology For example, electrode tips used in resistance welders must have electrical conductivity,
Softening resistance and high temperature strength are required. Conventionally, this electrode chip has been made by a method in which an ingot or an intermediate product made of a Cu-Cr alloy is rapidly cooled from a temperature of 900° C. or higher, quenched, and then subjected to an aging precipitation heat treatment.
発明が解決しようとする問題点

で溶接作業を行なえば電極チツプの先端が大きく
変形し、その結果溶接部の強度が不足するという
問題点が生じていた。Problems to be Solved by the Invention However, the copper-chromium alloy products manufactured by the above method had the following problems. For example, if we take the electrode tip used in a resistance welder as an example, if a large current flows through it and the tip reaches a high temperature, it will soften, and if welding is carried out at this high temperature, the tip of the electrode tip will be greatly deformed. As a result, a problem arises in that the strength of the welded portion is insufficient.
それゆえに、この発明の目的は、高温になつた
としても耐軟化性に優れ大きな荷重にも耐え得る
ような銅−クロム系合金製品の製造方法を提供す
ることである。 Therefore, an object of the present invention is to provide a method for manufacturing copper-chromium alloy products that have excellent softening resistance and can withstand large loads even when exposed to high temperatures.
問題点を解決するための手段
この発明による銅−クロム系合金製品の製造方
法では、まず、少なくともCrを0.1〜1.5％含有し

または線状体を冷間加工することによつて耐軟化
性に優れた製品を得る。Means for Solving the Problems In the method for manufacturing a copper-chromium alloy product according to the present invention, firstly, rapidly solidified alloy powder containing at least 0.1 to 1.5% Cr and the balance consisting of Cu is rotated. It is continuously supplied into the conduit formed between the driving wall surface and the fixed fixed wall surface. Thereafter, the alloy powder, which moves within the conduit due to the frictional force with the driving wall surface, is continuously extruded as a rod or linear body by an extrusion die provided at the end of the conduit. Then, by cold working the rod or linear body, a product with excellent softening resistance is obtained.
「少なくともCrを含有」するのは、Crが耐軟
化性に対して良好な影響をもたらすからである。
Cr含有量を「0.1〜1.5％」としたのは、0.1％未満
であるならば耐軟化性に対して効果がなく、1.5
％を越えれば耐軟化性に対する効果が飽和するか
らである。「残部がCr」であるのは、Cuが良好な
導電性を有するからである。「合金粉末」状に急
冷するのは、たとえば棒状にすることに比べて良
好な焼入性が得られるからである。 The reason why it "contains at least Cr" is that Cr has a good effect on softening resistance.
The reason why the Cr content was set to "0.1 to 1.5%" is because if it is less than 0.1%, it has no effect on softening resistance.
%, the effect on softening resistance is saturated. The reason why "the rest is Cr" is because Cu has good conductivity. The reason why it is rapidly cooled into the form of "alloy powder" is that better hardenability can be obtained compared to, for example, forming it into a rod shape.
合金粉末を、駆動壁面との摩擦力によつて移動
させ、その後押出しダイスによつて連続的に棒状
体もしくは線状体として押出すのは、以下の理由
による。すなわち、管路内に供給された合金粉末

発熱に加えて、合金粉末に押込み力による外部か
らの圧縮力が加わると、合金粉末は互いに金属接
合される。そしてこの際、Crがほど良く時効析
出される。 The reason why the alloy powder is moved by the frictional force with the driving wall surface and then continuously extruded as a rod or linear body by an extrusion die is as follows. That is, the alloy powder supplied into the pipe generates heat due to the sliding force between the powders caused by internal plastic flow based on friction within the pipe. In addition to this heat generation, when an external compressive force due to a pushing force is applied to the alloy powder, the alloy powder is metallurgically bonded to each other. At this time, Cr is properly aged and precipitated.
また、押出し後に熱間加工ではなく「冷間加
工」するのは、再結晶による過時効を避けるため
である。 Furthermore, the reason why "cold working" is performed instead of hot working after extrusion is to avoid overaging due to recrystallization.
合金粉末は、好ましくは、Crに加えて、Ag，
Sn，Al，Si，Mg，Zr，Feからなる群から選ば

耐軟化性等を向上させる効果があるからである。 The alloy powder preferably contains Ag, in addition to Cr.
Contains a total of 0 to 1% of one or more elements selected from the group consisting of Sn, Al, Si, Mg, Zr, and Fe. This is because addition of these elements has the effect of improving strength, softening resistance, etc.
