Abstract

The invention discloses a deformation correcting device for welded tubes. The deformation correcting device is convenient to use and good in deformation correcting effect. The device comprises a portal frame arranged on an installing base, a movable base which can move in the vertical direction is movably arranged in the portal frame, and a rotating shaft is arranged on the movable base. The rotating shaft is sleeved with a main worm gear and a rotating base, the movable base is provided with a main worm driving the main worm gear, and a through hole is formed in the center of the rotating base and used for allowing the welded tube to penetrate. Three or more shaping assemblies are evenly distributed in the circumferential direction of the through hole in the rotating base. Each shaping assembly comprises a fixing plate arranged on the rotating base, the fixing plates are connected with sliding bases through bolts, wherein the sliding bases move in the radial direction of the through hole, and shaping rollers are arranged on the sliding bases and are perpendicular to the moving direction of the sliding bases and rotate freely. Limiting pressing strips are arranged on the parts, on the two sides of each sliding base, of the rotating base. The shaping faces of the shaping rollers are circular arc surfaces of which the diameter is the same as the diameter of the peripheries of the welded tubes, and the total circular arc length of all the shaping faces accounts for over 80% of the length of the peripheries of the welded tubes.

Description

technical field [0001] The invention relates to an orthopedic device for a welded pipe. Background technique [0002] After the welded pipe is welded, due to the effect of welding thermal stress, the pipe will be deformed to a certain extent, and this deformation will directly affect the quality of the pipe. Therefore, the welded pipe needs to be corrected by a series of orthopedic devices to correct this deformation. The position where the welded pipe is seriously deformed during welding may be different on different production lines, but the shaping roller of the existing orthopedic device cannot be adjusted relative to the circumferential position of the pipe, which makes the roller shaft of the orthopedic roller more susceptible to flexural stress. large, affecting the shaping effect and shortening the life of the orthopedic roller. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an orthopedic device for a we...
