Abstract
The utility model belongs to a rounding device, and in particular relates to a pipe mouth rounding device of a heavy-caliber steel pipe. The pipe mouth rounding device solves the problems that the rounding method of the present steel pipe can damage the surface of the steel pipe and affect the surface quality of the steel pipe, and the welding quality cannot be well ensured. The pipe mouth rounding device of the heavy-caliber steel pipe comprises a rounding core disc; a plurality of threaded holes which are uniformly distributed oppositely to the center of the rounding core disc are arranged at the side face of the rounding core disc, each threaded hole is provided with a dual-head bolt and a rounding mould, the top part of the rounding mould is circular arc-shaped, a threaded hole is also arranged at the bottom part of the rounding mould, one head of the dual-head bolt is a positive buckle, the other head of the dual-head bolt is a negative buckle, one head of the dual-head bolt is matched with the threaded hole on the rounding core disc, and the other head of the dual-head bolt is matched with the threaded hole on the rounding mould. The beneficial effects of the pipe mouth rounding device are as follows: the pipe mouth rounding device can effectively modify the non-round condition of a pipe mouth, is suitable for being used in installing as well as butt welding fields of the steel pipe, and can quickly succeed in butt welding two steel pipes with non-round pipe mouths. Moreover, the construction time is shortened, the working efficiency is improved, and great convenience is brought for welding.
Description
Technical field
The utility model belongs to rounding device, is specifically related to a kind of large-diameter steel pipe mouth of pipe rounding device.
Background technology
The heavy caliber welded still pipe mouth of pipe is not round, brings inconvenience to welding procedure.And at present, also do not have good large caliber pipe mouth full circle device, and the steel pipe butt welding that the mouth of pipe is not round, great majority adopt the light instrument support to drag and solve.This kind mode, though simple, steel tube surface there is damage, influence surface quality, the also bad assurance of welding quality.
Summary of the invention
The utility model has damage in order to solve existing steel pipe full circle mode to steel tube surface, influences steel tube surface quality, and the problem of the bad assurance of welding quality, and a kind of large-diameter steel pipe mouth of pipe rounding device is provided.
The utility model adopts following technical scheme to realize:
Large-diameter steel pipe mouth of pipe rounding device, it is characterized in that comprising full circle core dish, stud and full circle mould, full circle core dish side has some screwed holes of the uniform setting of relative full circle core disk center, each screwed hole sets a stud and a full circle mould, full circle mould top is that circular arc, bottom also have screwed hole, one of stud is a left-hand thread for right-hand thread, other end, one of stud cooperates with screwed hole on the full circle core dish, and the other end cooperates with screwed hole on the full circle mould.
Stud two is provided with the full circle bolt sleeve respectively.Full circle core dish is eight prisms.
The utlity model has following beneficial effect: the round situation of the mouth of pipe can be repaired effectively, be specially adapted to the butt welding scene is installed at steel pipe, by full circle can be quickly that two root canal orifices are round steel pipe to being welded into merit.Like this, can shorten the engineering time, increase work efficiency, bring great convenience to welding.
