Abstract
The utility model discloses a kind of large-scale steel pipe straightener, comprise frame, it is characterized in that: described frame is furnished with two rows roll extrusion wheels, described lower row's roll extrusion wheels are active wheels, its each lower rolling wheel is connected with independently drive unit, and described upper row's roll extrusion wheels are limited a wheels, and its each upper rolling wheel is provided with cambered surface groove, adopt between described upper rolling wheel and frame and flexibly connect, the upper rolling wheel stated and lower rolling wheel are in intersecting opposed distribution.By the way, the utility model can carry out straightening to large diameter steel pipe.
Description
Technical field
The utility model relates to metal working technical area, particularly relates to a kind of large-scale steel pipe straightener.It is suitable for the straightening of large diameter steel pipe.
Background technology
In prior art, when the steel pipe larger to diameter carries out straightening, steel pipe is needed to be put on two fulcrums, mechanical compression is carried out to the part of distortion, market such as, common are gantry frame type straightener, this straightening pattern needs accurately to grasp pressing force and pressing stroke, misoperation, easily steel pipe is caused to the damage of unrepairable, at present, the tubing steel that bar straightener is less to diameter have good straightening effect, but due to large-scale steel pipe intensity large, enough driving forces cannot be provided, also cannot carry out straightening operation to it.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of specially for the steel pipe straightening machine of large diameter steel pipe straightening.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of large-scale steel pipe straightener, comprise frame, it is characterized in that: described frame is furnished with two rows roll extrusion wheels, described lower row's roll extrusion wheels are active wheels, its each lower rolling wheel is connected with independently drive unit, described upper row's roll extrusion wheels are limited a wheels, its each upper rolling wheel is provided with cambered surface groove, adopt between described upper rolling wheel and frame and flexibly connect, the upper rolling wheel stated and lower rolling wheel are in intersecting opposed distribution.
In solution technique, flexible locating part can adjust the roll extrusion power of rolling wheel, reaches optimum duty, and described lower rolling wheel leads to board independently drive unit drive, has enough driving forces.。
The beneficial effects of the utility model are: it is high that the utility model has operating efficiency, the advantage that straightening is effective.
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, frame 2, lower rolling wheel 3, upper rolling wheel 4, cambered surface groove.
Detailed description of the invention
Below in conjunction with accompanying drawing to embodiment further instruction.
A kind of large-scale steel pipe straightener, comprise frame, described frame 1 is furnished with two rows roll extrusion wheels, described lower row's roll extrusion wheels are active wheels, its each lower rolling wheel 2 is connected with independently drive unit, and described upper row's roll extrusion wheels are limited a wheels, and its each upper rolling wheel 3 is provided with cambered surface groove 4, adopt between described upper rolling wheel 3 and frame 1 and flexibly connect, described upper rolling wheel 3 and lower rolling wheel 2 are in intersecting opposed distribution.
In solution technique, the travel path of steel pipe when cambered surface groove can guarantee straightening.
It is high that the large-scale steel pipe straightener of this spline structure has operating efficiency, the advantage that straightening is effective.
