【発明の詳細な説明】
本発明はスポット溶接技術、特にスポット溶接機用電極
（以下ｊｌに電極という）の清浄方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to spot welding technology, and in particular to a method for cleaning an electrode for a spot welder (hereinafter referred to as "electrode").
従来、亜鉛メッキ鋼板等の表面処理鋼板のスポット溶接
において、溶接を長く続けると、電極表面に、表面処理
鋼板の表面被覆層物質と、電極材クロム銅中の銅とが合
金を形成して、電極表面に付着し、これが原因となって
電極消耗を促進し、溶接品質が不安定となる欠点がある
。Conventionally, in spot welding of surface-treated steel sheets such as galvanized steel sheets, if welding continues for a long time, the surface coating layer material of the surface-treated steel sheet and the copper in the chromium copper electrode material form an alloy on the electrode surface. It has the disadvantage that it adheres to the electrode surface, which accelerates electrode wear and makes welding quality unstable.
このため、電極表面に付着した不純物を削除するために
、ヤスリ仕」−げやワイヤブラシ掛は等を行っているが
、これらの方法では、付着不純物の削除に時間がかかっ
たり、削除状態（再生品品質）のバラツキが避けられな
いなどの欠点がある。For this reason, in order to remove impurities attached to the electrode surface, sanding, wire brushing, etc. are performed, but these methods take time to remove the attached impurities and leave the removed state ( There are disadvantages such as unavoidable variations in the quality of recycled products.
本発明は電極表面に付着した不純物を、容易かつ確実に
削除できるスポット溶接機用電極のＩｎ浄方法を提供す
ることを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to provide a method for cleaning an electrode for a spot welding machine with In, which can easily and reliably remove impurities attached to the electrode surface.
このような目的は、不純物が付着した電極表面に、砥石

って吹き付けて、電極表面付着物を削除することを特徴
としたスポット溶接機用電極の清浄方法によって達成さ
れる。The purpose of this is to use spot welding, which is characterized by removing impurities on the electrode surface by spraying fine hard particles such as grinding stones, sand, metal powder, steel balls, etc. with high-pressure gas onto the electrode surface to which impurities have adhered. This is achieved by a method of cleaning mechanical electrodes.
以下添付図面に基づいて、本発明の詳細な説明する。図
は本発明法により、電極を清浄している状態を示す。The present invention will be described in detail below based on the accompanying drawings. The figure shows an electrode being cleaned by the method of the present invention.
電極１の表面に不純物が付着して汚れた時には、図に示

〜８ｋｇ ／ ｃ−の高圧エアーでｍ極１表面に吹き付
けることにより、電極１表面の付着不純物を削除するも
のである。When the surface of the electrode 1 is contaminated with impurities, the guide nozzle 2 sprays fine hard particles such as sand onto the surface of the electrode 1 at positions approximately 1 to 41 from the surface of the electrode 1, as shown in the figure.
2, and place fine hard particles such as sand from the direction of arrow 4.
Impurities adhering to the surface of the electrode 1 are removed by spraying the surface of the m-electrode 1 with high-pressure air of ~8 kg/c-.
このとき、電極１表面のｌηれ稈度によって、砂の大き
さ及び形状、高圧エアー圧力、砂を吹き付ける時間を適
当に調節することにより、電極１表面の削除度合を容易
に調整できる。At this time, the degree of removal of the surface of the electrode 1 can be easily adjusted by appropriately adjusting the size and shape of the sand, the high pressure air pressure, and the sand blowing time depending on the degree of curvature of the surface of the electrode 1.
また、案内ノズル３は、案内ノズル２から高圧エアーで
電極１表面に吹き付けた砂等を回収するための案内パイ
プで、電極１表面に砂等を吹き付けろ高圧エアーを利用
して砂等を回収するものである。In addition, the guide nozzle 3 is a guide pipe for recovering sand, etc. blown onto the surface of the electrode 1 using high pressure air from the guide nozzle 2. It is something to do.
案内ノズル３と電極１との間隙５は、０．２ｍｍ程度と
し、電極１と案内ノズル２の位置決めをする作用と、高
圧エアーでとばされた砂等が案内ノズル３から周辺に飛
散しない範囲にしている。The gap 5 between the guide nozzle 3 and the electrode 1 is approximately 0.2 mm, which serves to position the electrode 1 and the guide nozzle 2 and to prevent sand, etc. blown by high-pressure air from scattering from the guide nozzle 3 to the surrounding area. I have to.
なお、案内ノズル３からの砂のもれを完全になくするに
は、中抜き円錐形状のバネ鋼、ゴムカーテン等のシーリ
ング部材６を設けることによってシーリング可能である
。In order to completely eliminate sand leakage from the guide nozzle 3, sealing can be achieved by providing a sealing member 6 such as hollow conical spring steel or a rubber curtain.
以」二により明らかなように、本発明にかかる電極の清
浄方法によれば、電極表面に付着した不純物を短時間で
かつ確実に削除でき、電極を清浄表面とすることができ

、吹き付は時間等の調節によって、表面削除量を自由に
制御できるので、手動・自動いづれにおいても、適正な
表面削除条件を容易に決めることができる利点がある。As is clear from the following, according to the electrode cleaning method of the present invention, impurities attached to the electrode surface can be removed reliably in a short time, and the electrode can not only have a clean surface. The amount of surface removal can be freely controlled by adjusting the size and shape of the sand, the gas pressure for blowing, the time for blowing, etc., so it is easy to determine the appropriate surface removal conditions, whether manually or automatically. There are advantages that can be achieved.
