Work efficiency can be improved；
The utility model sets T steel bending tool by two lower rolls or upper roller, and the crossbeam of T steel can be as common roll bending
It is bent, vertical beam is in the opening between two arcs, is free state, is driven by crossbeam and do synchronous bending, so as to complete T
The integrally bending of shape steel；It is not only high in machining efficiency due to school circle need not be carried out, and finished product radian can ensure that by veneer reeling machine control
The arc accuracy of T steel is bent, prevents large scale cylinder part welding deformation hidden danger, it is ensured that product quality is up to standard；
As of the present utility model a kind of preferred, more than one piece of reinforcement is fixedly connected with every piece of lateral surface of arc
Plate；Both the rigidity of arc can have been strengthened so that axially vertical with upper roller or lower roll, arc can have been improved again in buckling work
Compressive resistance；
As one kind of the present utility model preferably, the side that two arcs of each clamp body are adjacent is equipped with chamfering；Work as T
When there is larger angle welding the vertical beam both sides of shape steel, it is ensured that T steel is installed in place in frock；
As one kind of the present utility model preferably, the internal diameter of limit for width connecting plate is equal with the internal diameter of both sides arc；Limit for width
The inner arc surface of connecting plate can also be held tightly to lower roll or upper roller, can improve steadiness of the frock in axially position；
In sum, the utility model not only has the advantages that to be easy to that processing, weld seam is few, deformation is small, also easy guarantee arc
Plate is used for the intrados of fixed and positioned workpiece and the precision of extrados, and without processing welding lines, can improve work efficiency.
