Title:
CORRECTION DEVICE FOR TITANIUM PIPE WALLS
Document Type and Number:
WIPO Patent Application WO/2022/110254
Kind Code:
A1
Abstract:
A correction device for titanium pipe walls, which relates to the technical field of correction devices. The device comprises a housing (1), an inner wall of the housing (1) is cooperatively and rotatably connected to a rotary disc (2), projection blocks (3) are welded to the inner wall of the rotary disc (2), a cross bar (4) is cooperatively and slidably connected to the inner wall of the rotary disc (2), extension blocks (7) are welded to the surface of the cross bar (4), a moving block (6) is cooperatively and slidably connected to the surface of the cross bar (4), the inner wall of the moving block (6) is cooperatively and slidably connected to inclined surfaces (8), a fixing block (10) is welded to the surface of the moving block (6), and fasteners (12) are cooperatively and slidably connected to the surface of the fixing block (10). By means of the cross bar (4), correction to all inner walls of a pipe can be made from the outside, thus greatly increasing the overall usage efficiency, and the grinding and correction of pipes of different diameters are achieved by means of mutual cooperation among the inclined surfaces (8) and the extension blocks (7); in addition, by means of the mutual cooperation between a pipe wall frame (18) and telescopic rods (15), workers can conveniently perform work from the outside, thus reducing labor consumption.
