Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
Seeing Fig. 1, is the structural representation of deslagging device of the present invention.Welding slag sweep-out method after spiral welded pipe inside weld of the present invention reconditioning, comprises the steps:
1) spiral welded pipe weld seam shaping after, inside weld adopts inside weld sharpening machine reconditioning weld seam to qualified;
2) grinding wheel being arranged on outside weld sharpening machine rotating shaft 2 axle head is unloaded, wire brush 4 is installed; Wire brush 4 is fixedly connected with outside weld sharpening machine rotating shaft 2 by wire brush axis 3, and can rotate with outside weld sharpening machine rotating shaft 2;
3) start outside weld sharpening machine 1, wire brush 4 rotates under rotating shaft 2 drives, and wire brush 4 removes welding slag while the movement of spiral welded pipe inside weld;
4) different according to steel pipe caliber, the height of wire brush 4 adjusts by outside weld sharpening machine 1 vertical guide rail;
5) when needs carry out outside weld reconditioning, wire brush 4 and wire brush axis 3 entirety are disassembled from outside weld sharpening machine rotating shaft 2 axle head, reinstalls grinding wheel.
For realizing the deslagging device of welding slag sweep-out method after the reconditioning of spiral welded pipe inside weld, comprise wire brush 4 and wire brush axis 3, described wire brush axis 3 one end is fixedly connected with by screw thread with outside weld sharpening machine rotating shaft 2 axle head, wire brush 4 inner ring is fixedly connected with wire brush axis 3 by long key 5, and outside weld sharpening machine rotating shaft 2 drives wire brush 4 to rotate by wire brush axis 3; Wire brush 4 axle head is fixed by locking nut 6.
