The utility model further improvement project is, described drive roll, bending roller, limiting roll are all vertically arranged in fixed frame and rotate, the framework of described fixed frame to be front end face be opening, the opening of the fixed frame at the opening of the fixed frame at described drive roll place and described bending roller, limiting roll place is oppositely arranged.
The utility model further improvement project is, two side, described each fixed frame front end is provided with the circular arc cutaway of passing for workpiece.
The utility model further improvement project is, is connected after place fixed frame is stretched out in the rotating shaft of described drive roll downwards with the output shaft of described reductor.
The utility model further improvement project is, the rear end face of the fixed frame at described bending roller place is connected with the piston rod of described hydraulic cylinder, and described hydraulic cylinder is fixed on the side of operating platform.
The utility model further improvement project is, the fixed frame at described limiting roll place is fixedly connected with on the operational platform.
The utility model further improvement project is, the both sides of described bending roller are fixed with pressing plate respectively, and the opposite face of two pressing plates is provided with chute, and the base plate both sides of the fixed frame at described bending roller place put in described chute to coordinate slides.
Compared to the prior art the utility model has the following advantages:
The utility model structure is simple, operating platform is established the drive roll that reductor drives, reductor can the larger moment of torsion of transmission, ensure that drive roll has enough power conveying workpieces to move ahead, bending roller by Driven by Hydraulic Cylinder, bending roller forward slowly movement can increase the load be applied on workpiece gradually, thus process the steel pipe of different radian, the wide accuracy of the range of work is high, and limiting roll plays spacing function, prevents workpiece tail swing from guaranteeing carrying out smoothly of bending.During use, workpiece is put in after between drive roll and limiting roll and start reductor, now workpiece is fed forward then unlatching hydraulic cylinder and makes bending roller extruding workpiece formation radian, the utility model reductor and hydraulic cylinder with the use of, driving force and loading force large, be particularly useful for the long-span steel pipe of shaping certain radian, use simple, Slow loading guarantee shaping after workpiece radian natural beauty.
