【考案の詳細な説明】
〔産業上の利用分野〕
本考案は、炭酸ガスアーク溶接などに使用され
る電気溶接機において、溶接用のワイヤーに給電
を行うためにトーチの先端部に交換可能に装着さ
れる電気溶接用チツプ（以下、単に「チツプ」と
略称する）に関するものである。[Detailed description of the invention] [Industrial application field] This invention is an electric welding machine used for carbon dioxide arc welding, etc., and is replaceable at the tip of the torch to supply power to the welding wire. This invention relates to an electric welding tip (hereinafter simply referred to as a "chip").
従来のチツプは、クローム銅に切削加工と穿孔
加工を施して製作されているが、その材質の硬度
が高いために加工が難しく、特にワイヤーを挿通
させるために軸心に設けるワイヤー挿通孔は、そ
の孔径が小さい（直径0.8mm〜1.3mm）のみなら
ず、その長さが孔径の40〜60倍位あるので、穿孔
加工を更に困難にしている。
Conventional chips are manufactured by cutting and drilling chrome copper, but the high hardness of the material makes machining difficult, especially the wire insertion holes that are made at the center of the shaft for the wires to pass through. Not only is the hole diameter small (0.8 mm to 1.3 mm in diameter), but its length is about 40 to 60 times the hole diameter, making drilling even more difficult.
このワイヤーは、ワイヤー送給装置に巻回され
ているものを巻き戻しているために、巻き癖が付
けられている。このワイヤーがチツプのワイヤー
挿通孔に挿通された状態では、その巻き癖によつ
て、通常チツプの入口、中央部、及び出口の三箇
所において夫々チツプに接触しており、これによ
りチツプを介してワイヤーに給電される。 This wire has curls because it is unwound from the wire feeding device. When this wire is inserted into the wire insertion hole of the tip, due to its curl, it usually contacts the tip at three locations: the entrance, the center, and the exit of the tip. The wire is powered.
この状態が長く続いてワイヤーが順次繰り出さ
れてゆくと、チツプのワイヤー挿通孔の先端が摩
耗してその径が次第に大きくなる。このような状
態で、溶接作業が行われると、ワイヤーの先端部
が目標位置からずれてしまい、正確な溶接が行え
ない。特に、ロボツトを使用した溶接作業の場合
には、人手による溶接作業のように微妙な修正が
できないので、上記不具合は致命的となる。 If this state continues for a long time and the wires are fed out one after another, the tip of the wire insertion hole in the chip wears out and its diameter gradually increases. If welding work is performed in such a state, the tip of the wire will shift from the target position, making it impossible to perform accurate welding. In particular, in the case of welding work using a robot, the above-mentioned problems are fatal because delicate corrections cannot be made as in manual welding work.
また、電気溶接作業においては、チツプの先端
部にスパツタが付着し易く、このスパツタがチツ
プの先端部に付着すると、溶接用ワイヤーの送給
の抵抗となり、甚だしい場合には送給不能になる
ことさえある。このため、電気溶接作業において
は、チツプの先端部に付着したスパツタを定期的
に取り除かねばならない。 In addition, during electric welding work, spatters tend to adhere to the tip of the tip, and if these spatters adhere to the tip of the tip, they will create resistance to the feeding of the welding wire, and in extreme cases, it may become impossible to feed the welding wire. Even. Therefore, during electric welding work, it is necessary to periodically remove spatter adhering to the tip end of the chip.
そこで、チツプの軸心に形成されたワイヤー挿
通孔の先端部の摩耗の防止と、スパツタの付着の

うちに接触箇所のチツプの材質が剥がれるバーン
バツク現象が誘発される。 Therefore, in order to prevent both abrasion of the tip of the wire insertion hole formed in the axis of the chip and prevention of adhesion of spatter, we have developed A cap made of ceramic has been developed that is attached to the tip of the chip by caulking. According to this chip, each of the above-mentioned problems can be solved, but since the curl of the wire is forcibly corrected by the center hole of the ceramic cap, the wire and the inner circumferential surface of the wire insertion hole of the chip are Because the contact position changes depending on the degree (strength) of the wire curl, the power supply becomes unstable (specifically, the supplied current changes), which has a negative impact on welding work, and the contact The chips themselves become unstable, and as they repeat contact and non-contact, a burnback phenomenon occurs in which the material of the chip at the contact point peels off.
これを防止するために、第１０図に示されるよ

しく高価となる。 In order to prevent this, a wire insertion hole is inserted into the center wall of the chip, as shown in FIG.
A contact chip 9 is fitted into the spring 9 at right angles to the contact tip 9 attached to the tip of the spring 9.
A is used to constantly press the wire A against the inner peripheral surface of the wire insertion hole 1 on the body surface side, thereby ensuring secure contact between the wire A and the chip. However, even with this arrangement, since the chip itself is at a high temperature, the spring 9 deteriorates due to heat and no longer performs its pressing function, and the chip becomes extremely expensive due to the installation of the spring 9.

In view of the above-mentioned problems with conventional chips, the present invention has been developed to stably supply power to the wire at the tip of the chip body, and to prevent wear on the tip of the wire insertion hole formed in the chip. It is an object of the present invention to provide a chip that can simultaneously prevent adhesion of spatter.

The means adopted by the present invention to solve the above problems is that a ceramic cap is attached to the tip of a chip body consisting of a pair of divided bodies vertically divided into two parts passing through the axis of the chip body. By forming a groove having a bent part on the surface where each divided body comes into close contact with each other and integrating each divided body,
A bent portion is formed near the tip of the wire insertion hole formed in the axis of the chip body by the slot and connected to the center hole of the ceramic cap.

先端部分に屈曲部を形成することができるので、
一定の電圧に対して大きな供給電流が得られる。[Operation of the device] The chip body is divided into two in the vertical direction, and slots with bent parts are formed in the surfaces of the divided bodies that come into close contact with each other, so that the two divided bodies are integrated. A bent portion is provided in the wire insertion hole formed by the slot at the axis of the chip body. Therefore, a wire insertion hole having a small hole diameter and a bent portion in the middle can be easily formed in the chip body. Since the wire is fed through this bent portion, the chip body and the wire are surely in contact with each other, and since the contact position is constant, the power feeding is stable. Moreover, since a bent part can be formed at the tip of the wire insertion hole,
A large supply current can be obtained for a constant voltage.

なる。 In addition, the tip of the tip is equipped with a cap made of ceramic, which has high wear resistance and ability to remove deposits, so the diameter of the tip of the wire insertion hole can be adjusted even when the wire is fed. It does not become larger due to wear, and the tip of the wire always remains in the target position during welding work. In addition, spatter is less likely to adhere to the tip of the chip body, and adhering spatter can be easily removed.
