本考案は、シーム溶接機の電極成形装置の改良
に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of an electrode forming device for a seam welding machine.
（従来技術）

抵抗が益々大きくなつて電極輪と被溶接物との間
にスパークが一層激しく発生する。(Prior art) A seam welding machine consists of a pair of electrode rings, and while the workpiece is sandwiched between the pair of electrode rings and passes between these electrode rings, the flow from the workpiece to the electrode rings passes through the electrode rings. The seam is welded continuously by the welding current. The objects to be welded are usually subjected to a surface treatment such as galvanizing for rust prevention or the like. This surface treatment material tends to adhere to the electrode ring due to the heat during seam welding and sparks between the electrode ring and the workpiece, resulting in minute irregularities on the surface of the electrode ring. . If the welding operation is continued in this state, the electrical resistance will increase and more sparks will be generated between the electrode ring and the workpiece.
シーム溶接機の電極成形装置は、このような電

案内部材は、バイトが電極輪に接近して配置され
て電極輪に接触するのを確実にするため、電極輪
に接触して給電する給電部に絶縁物を介して取付
けられている。 The electrode forming device of the seam welding machine is installed close to the electrode ring in order to scrape off such adhesive substances on the surface of the electrode ring. This electrode forming device includes a cutting tool that contacts the electrode wheel in a movable manner, a tool rest that supports the tool rest, and a guide member that supports the tool rest so that it can move back and forth on the electrode wheel.
The guide member is attached via an insulator to a power supply part that supplies power by contacting the electrode ring in order to ensure that the cutting tool is placed close to the electrode ring and comes into contact with the electrode ring.
バイトは、電極輪の凝着物の発生量に応じて常

動によつてこの振動を受けて案内部材との間で擦
れるため、刃物台と案内部材との間でもスパーク
が発生して電蝕現象が起き、それが激しくなる
と、作動不良となる。 The cutting tool is brought into contact with the electrode ring constantly or frequently depending on the amount of adhered substances generated on the electrode ring, and cuts the surface of the electrode ring to remove the adhered substances and smooth the surface of the electrode ring. On the other hand, when the cutting tool contacts the electrode ring, a part of the welding current flows through the cutting tool as well, and the tool rest receives vibrations caused by the vibration caused by the contact of the cutting tool with the electrode ring, and the guide member Because of the friction between the tool rest and the guide member, sparks are also generated between the tool rest and the guide member, causing electrolytic corrosion, and if this becomes severe, malfunction will occur.
また、案内部材が絶縁物を介して給電部に取付

なる欠点があつた。 In addition, since the guide member is attached to the power supply section through an insulator, the guide member is insulated from the power supply section, but the adhesive on the electrode ring has been scraped off and the part where the insulator is sandwiched. If the tool falls on top of the tool, current will flow through the scraped object, reducing its insulation function and causing intense sparks between the cutting tool and the electrode ring.
（考案の目的）
本考案の目的は、バイトと電極輪との間のスパ

成形装置を提供することにある。(Purpose of the invention) The purpose of the invention is to provide an electrode forming device for a seam welding machine that suppresses the generation of sparks between the cutting tool and the electrode ring, eliminates the electrolytic corrosion phenomenon, and prevents malfunctions. It's about doing.

を備えたことを特徴としている。(Structure of the invention) The electrode forming device for a seam welding machine according to the invention includes:
A cutting tool that contacts the electrode wheel of a seam welding machine, consisting of a pair of electrode wheels that are supplied with power from a power supply section, that can move forward and backward, a tool rest that supports this tool, and a guide that supports this tool rest that can move forward and backward with respect to the electrode wheel. The guide member is attached to the power supply part via an insulator, and is further equipped with an electrolytic corrosion prevention means consisting of a ground wire connected to the tool rest and grounding the tool rest. There is.

とができる。 In this way, if the guide member of the tool post is attached to the power supply section via an insulator to insulate it from the power supply section, and the tool post is grounded with the ground wire, the current flowing through the tool will be connected to the ground via the ground wire. This prevents the generation of sparks and electrolytic corrosion between the tool post and the guide member, and even if objects scraped from the electrode ring fall across the insulator, this Since the current flowing through the object is grounded, the spark suppression effect can be maintained.
