Abstract
The utility model relates to metal working technical area, particularly relate to a kind of steel pipe open arc cutting knife, comprise pedestal, described pedestal is extended with the drift consistent with pipe diameter, the cross section of described drift is arc-shaped, and the side of described drift is placed with supporting bearing, and described bearing leaves the hole with outer diameter of steel pipes size, the steel pipe open arc cutting knife of this spline structure has manipulation conveniently, the advantage that operating efficiency is high.
Description
Technical field
The utility model relates to metal working technical area, particularly relates to a kind of steel pipe open arc cutting knife.
Background technology
When two different butt welding of steel tube connect, need to carry out open arc to the end of one root steel pipe, the outer surface of the cross section of end and another root steel pipe is coincide mutually, and in prior art, the open arc of steel pipe adopts the mode of cutting, this operating type needs to be grasped open arc route, manipulation difficulty is high, and efficiency is low, also has the pattern adopting machine punching press, but steel pipe is in punching course, be easily crowded flat.
Utility model content
It is convenient that the technical problem that the utility model mainly solves is to provide a kind of manipulation, efficient steel pipe open arc degree cutting knife.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of steel pipe open arc cutting knife, comprise pedestal, described pedestal is extended with the drift consistent with pipe diameter, the cross section of described drift is arc-shaped, the side of described drift is placed with supporting bearing, and described bearing leaves the hole with outer diameter of steel pipes size.
The beneficial effects of the utility model are: the steel pipe open arc cutting knife of this spline structure has manipulation conveniently, the advantage that operating efficiency is high.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
In accompanying drawing, the mark of each parts is as follows: 1, pedestal 2, steel pipe 3, drift 4, bearing 5, hole.
Detailed description of the invention
Below in conjunction with accompanying drawing to embodiment further instruction.
As shown in Figure 1, a kind of steel pipe open arc cutting knife, comprises pedestal 1, described pedestal 1 is extended with the drift 3 consistent with steel pipe 2 internal diameter, the cross section of described drift 3 is arc-shaped, and the side of described drift 3 is placed with supporting bearing 4, and described bearing 4 leaves the hole 5 with outer diameter of steel pipes size.
During operation, steel pipe is put into bearing 4, until be inserted in drift 3, machine band moving base swings, and namely completes the open arc to steel pipe.
It is convenient that the utility model has manipulation, the advantage that operating efficiency is high.
