この発明は被溶接物を突合せ溶接するもので特に被溶接
物を強固に保持するようにしたフラッシュ溶接装置に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flash welding device for butt welding objects to be welded, and particularly to a flash welding device that firmly holds the objects to be welded.
従来のものは第１図及び第２図に示すように移２５動台

を切断する。The conventional type is a pressurizing cylinder fixed to a movable table 2 and a fixed table 1 as shown in FIGS. 1 and 2. , 8 to lower the upper electrode devices 50, 51 and lower the clamping tables 3, 4.
By clamping the objects to be welded 54 and 55 with the auxiliary clamp stands 13 and 14 and operating the electrode pressurizing devices 56 and 57, the 30 electrode bodies 32, 33, 44, 45
The objects to be welded 54 and 55 are clamped, respectively, and the cutting devices 52 and 53 cut the ends of the objects to be welded 54 and 55, respectively.
しかるのちに、電極加圧装置５６、５７の加圧力を零に

材５４，５５の出し代を調整する。Thereafter, the pressure of the electrode pressurizing devices 56, 57 is reduced to zero or the electrode pressurizing devices 56, 5 are moved upward.
The holding force of the objects to be welded 54 and 55 by 7 is made zero. Thereafter, the electrode stand 24 and the riha 3-25, 36, 37 are moved forward or backward by the electrode extension adjustment devices 30, 31, 40, 41, and are removed from the cut end of each workpiece 54, 55. The extension of the materials to be welded 54, 55 is adjusted so that the distance to the tip surfaces of the electrode bodies 32, 33, 44, 45 becomes a predetermined value selected according to the welding conditions.

Pressure 5.
以上によつて出し代の調整を行なつて溶接のための準備
は完了する。そこで移動台２を固定台１の方向に接近さ
せ、両被溶接物５４，５５を突合せてフラツシユ溶接を

できる構造となつている。つづいて、加圧シリンダ７，
８によつて上部電極装置５０，５１を上方に開放して各
装置は原位置にもどる。With the above adjustment of the protrusion margin, the preparation for welding is completed. Then, the movable table 2 is brought closer to the fixed table 1, and the two objects to be welded 54, 55 are butted together to complete the flash welding. At this time, the cutting devices 52 and 53 are constructed so that they can be removed from the line. Next, the pressure cylinder 7,
8, the upper electrode devices 50, 51 are opened upward and each device returns to its original position.
以上の説明から判明する通り、従来のフラツシユ溶接装
置においては、下記の欠点を有する。As is clear from the above description, the conventional flash welding apparatus has the following drawbacks.
即ち、（１）電極加圧装置を設置して電極部を加圧する
よ 二うになつているので、強大な加圧シリンダの加圧
力を利用することができないため、電極部による被溶接
物への加圧力が充分とはいえず、通電むらができて溶接
品質が低下しやすい。In other words, (1) an electrode pressurizing device is installed to pressurize the electrode part, so it is not possible to use the powerful pressurizing force of the pressurizing cylinder; The pressurizing force is not sufficient, and the welding quality tends to deteriorate due to uneven energization.
又、小形の電極加圧装置が要求され、剛性強 〉度上充
分でない上、加圧力確保のため高圧油圧を使用すること
となるので油もれが起りやすく、溶接部の近くでもあつ
て火災のおそれがある。In addition, a small electrode pressurizing device is required, which is insufficient in terms of rigidity and strength, and high pressure oil pressure is used to ensure pressurizing force, so oil leaks are likely to occur, and there is a risk of fire if the electrode pressurizes near welds. There is a risk of
（２）出し代調整装置が電極台と直結されているので、
アブセツト時の強大な力が直接出し代調整 ３装置に作
用し、出し代調整装置の寿命を著しく短かくするか、場
合によつては破壊に到ることもある。又油圧シリンダを
使用した場合などはアブセツトカによつて電極台が後方
に押しもどされる ３−現象がおき、溶接品質を低下さ
せる。(2) Since the extension adjustment device is directly connected to the electrode stand,
The strong force at the time of absorption acts directly on the extension adjustment device 3, which can significantly shorten the life of the extension adjustment device or even lead to its destruction. In addition, when a hydraulic cylinder is used, a phenomenon occurs in which the electrode stand is pushed back by the absorber, reducing welding quality.
（３）出し代は正確に設定されねばならないが従来のも
のでは出し代調整装置が直接に電極台を前後進させるた
め、出し代調整装置の中間停止精度がそのまま出し代の
精度となつて正確さに難 ４１点があつた。(3) The protrusion margin must be set accurately, but in conventional devices, the protrusion margin adjustment device directly moves the electrode table back and forth, so the intermediate stop accuracy of the protrusion margin adjustment device directly becomes the accuracy of the protrusion margin, making it accurate. It was difficult to score 41 points.
（４）出し代調整装置の中間停止精度を高めるには、移
動速度を極めておそくする必要があるので、出し代設定
に要する時間が長かつた。(4) In order to improve the intermediate stop accuracy of the extension adjustment device, it is necessary to make the moving speed extremely slow, so it takes a long time to set the extension.
この発明は上記欠点を解消するためになされたもので、
被溶接物をクランプする第１の押圧装置と、電極装置を
押圧する第２の押圧装置とを設けることによつて、被溶

る。This invention was made to eliminate the above drawbacks.
By providing the first pressing device that clamps the workpiece and the second pressing device that presses the electrode device, the extension of the workpiece can be set accurately and quickly, and the An object of the present invention is to provide a flash welding device that can firmly hold a workpiece to be welded against upset forces.
