Full -automatic arc butt welder of bending

The utility model discloses a full -automatic arc butt welder of bending, construct its characterized in that including arc O press structure, welding mechanism, clamp frame mechanism, thread cuttingmechanism, straightening mechanism and wire conveying machine: arc O press constructs including compriseing mold core and eccentric rotating shaft at least, the mold core sets up in eccentric rotatingshaft's axle center, and eccentric rotating shaft rotates around the mold core relatively. Rotate to press through drive eccentric rotating shaft and hold the shaping of bending of arc that metal wire realized metal wire along the mode of mold core shape, rotate with the gear mechanical drive eccentric rotating shaft that bends through the rack of bending simultaneously, make forming mechanism overall structure simple, easily the operation realize, low cost moreover, the shaping is of high quality, in addition through combining arc O press structure and welding mechanism etc. The automatic integration of welding that
