Under the pulling of the spring on the straightening cone 420, the straightening cone 420 is always abutted against the arc-shaped steel plate 100. In the process that the driving assembly 430 drives the two straightening cones 420 to be far away from each other through the straightening frame 410, the straightening cones 420 are always abutted against the arc-shaped steel plates 100 and slide under the pulling of the springs on the straightening cones 420.
When the two centering frames 410 are far away from each other, the centering frames 410 push the piston rods of the first hydraulic cylinders 521 so that hydraulic oil in the first hydraulic cylinders 521 is pressed into the second hydraulic cylinders 522, the piston of the second hydraulic cylinders 522 is driven to drive the piston rods of the second hydraulic cylinders 522 to approach the arc-shaped steel plates 100, the piston rods of the second hydraulic cylinders 522 drive the centering plates 510 to move towards the arc-shaped steel plates 100 through the centering rods 524, and the middle parts of the centering plates 510 are abutted against the arc-shaped steel plates 100 so as to clamp the two arc-shaped steel plates 100, so that the axes of the two arc-shaped steel plates 100 are overlapped.
The two centering brackets 410 continue to move away such that the centering rod 524 slides relative to the second hydraulic cylinder 522 piston rod. The righting rod 524 makes the hydraulic oil in the piston rod of the second hydraulic cylinder 522 enter the outer cavity of the sealing cavity 523 through the inner cavity of the sealing cavity 523 so as to drive the pressing rod 525 to approach the arc-shaped steel plate 100, so that the upper edge and the lower edge are bent towards the arc-shaped steel plate 100 and are attached to the arc-shaped steel plate 100, and a pressing force in the vertical direction is provided for the two arc-shaped steel plates 100 so as to clamp the two arc-shaped steel plates 100 coaxially.
The two arc-shaped steel plates 100 are then straightened and spot welded together using the spot welding assembly 710. Then, the support roller 310 rotates to drive the arc-shaped steel plates 100 to rotate, so that grooves on two sides of the arc-shaped steel plates 100 are positioned on the same vertical surface, and then the two arc-shaped steel plates 100 are welded and joined by the joint assembly 720. After the seam is completed, the two straightening cones 420 are driven to be away from and separated from the arc-shaped steel plate 100. Subsequently, the workpiece after the joint is pulled up by the hoist to elastically deform the holding plates 510, and then the workpiece is pulled out of the two holding plates 510.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
