Cylindring material cupling device using electromagnetic forming

The present invention aims to be formed by dividing the magnetic core for performing electromagnetic forming, and facilitates the positioning of the magnetic core and the bonding object, to facilitate the extraction of the bonded object after completion improve the work efficiency. The present invention means the case of forming the entire outer frame and to it; As new facing each other in the transverse direction of the bonded object to be erected at the center loading, onto which is disposed a lower portion of the case onto a means to give to the support by the hydraulic pressure, the horizontal direction at the lower side, and the support means; Comprising the said case means electromagnetic forming process means are disposed in the transverse direction in the central portion of as the magnetic core of the formed semi-circular partition to both sides stretching face each other in the transverse direction to the bonding process the joining portion of the joining objects positioned in the central portion It provides a bonding device of a cylindrical material formed by the electromagnetic forming method. A magnetic core, an electromagnetic induction coil, a field shaper
