Step eight: and hoisting a 4 th U-shaped thin plate, and after the 4 th U-shaped thin plate is placed, completing clamping of the 3 rd U-shaped thin plate according to the fifth step to the seventh step.
Step ten: the seventh telescopic piece drives the tail assembly to stretch out and push tightly. And the third supporting plate and the fourth supporting plate on the right side of the third outer container assembly sequentially extend out, so that the 4 th U-shaped thin plate is clamped and compressed, and the thin plate is installed.
The internal process flow of the turning welding of the thin plate is as follows:
and after the welding of the external welding seam is finished, turning over the tool. The inside butt weld of 3 positions altogether, when welding 1 st welding seam, the third backup pad and the fourth backup pad of outer courage subassembly, inner bag subassembly angle supporting shoe, first backup pad and second backup pad are packed up in proper order. Then, the first telescopic piece on the base assembly retracts, and when the first inner container assembly and the first outer container assembly are synchronously pulled apart (the inner container and the outer container are synchronously moved by the bolt), the position of the inner weld bead is displayed. And then the cylinders on the first inner container assembly and the first outer container assembly extend out in sequence to clamp the workpiece again. Internal welding may then be performed.
And after the welding of the 1 st welding channel is finished, presenting the 2 nd welding seam by the same action flow, and welding. Thereby, the 3 rd weld was welded. Namely, the welding of all the inner welding passes is completed.
