Description
Technical field
The present invention relates to building pipe processing technique field, the building pipe of specially a kind of double-station accurate positioning is welded
Device.
Background technique
Tubing is exactly the material for making pipe fitting, and the quality of the different tubing of different pipe fittings, tubing directly determines
The quality of pipe fitting, tubing are materials necessary to architectural engineering, with the development of science and technology, the tubing that house decoration uses
It experienced the development course of plain cast iron pipe, pipe of cement, ductile iron pipe, coating steel pipe, plastic tube and aluminum plastic composite pipe, tubing
The support and transmission material indispensable as building field, is widely used in building field, applies generally for satisfaction
Work, the demand used etc., need to change pipe length, with fixed length when usual tubing is bought from producer
Degree, therefore in use, it needs for pipe length to be adjusted, needs to cut when too long compared to needed length, by
In pipe cutting equipment, and it is too short compared to needed length when, then need to weld.
However, existing equipment when welding building pipe, needs to use manual operation by two building pipes
Welding position carries out grinding process, is then directed at the welding position of two building pipes, tubing is in the welding process by tubing
The influence of structure usually rotates the tubing after welding after tubing welded one side, then again to tubing another side
Welded, carry out welding when, need manually to be operated, it is not only time-consuming and laborious, and work when
It waits, manpower is limited, and can not be carried out continuously the biggish manual labor of intensity, and it is prolonged to work, and be easy to make in docking
It is the problems such as at weldering, solder skip partially occur at welding position, just very high into tubing its own temperature for crossing welding processing, manually into
The work of row overturning is very difficult, the work overturn after the temperature of tubing can only be waited to decline, and in cooling mistake
Cheng Zhong, tubing itself is it is possible that deformation, to influence the effect of following process, while present device can only manage one
