Background technique

H-shaped steel is widely used in large-scale buildings, water conservancy bridges, metallurgical industry and other industries. This kind of H-shaped steel is usually formed by welding. The plate is bent and deformed, so it needs a straightening machine to straighten it.

The applicant found that if the steel column specifications are H850*300*25*30, the material is Q345B, and the length is more than 8m, the flange plate is only 300mm. thicker, so the deformation of the flange plate after welding is also relatively large. Such a member with narrow and thick flange plate and relatively thick web has never been encountered in previous construction, and it is a difficult problem in rectification. If the existing straightening machine is used to straighten this kind of steel, the inner corners of the flange plate of the H-shaped steel will be pressed down a lot, that is, the pressure roller of the straightening machine can only press down the outermost edge of the flange plate, which will affect the structure of the component. The appearance quality is seriously affected, and the requirements in the quality specification cannot be met. To solve the above problems, the applicant improved the structure of the existing straightening machine.

The technical scheme adopted by the utility model: H-shaped steel flange straightening machine, which includes a machine base, a left rolling mechanism, a right rolling mechanism, a transmission roller table and a controller, and is characterized in that the left rolling mechanism includes a rolling mechanism A pressing assembly and a guide assembly, wherein the rolling assembly is composed of a pressing roller, a connecting shaft and an elevator, the pressing roller is rotatably fixed on the end of the connecting shaft, the connecting shaft is horizontally fixed on the telescopic arm of the elevator, and the connecting shaft can be The telescopic arm of the elevator moves up and down, and the elevator is fixed on the base; the guide assembly is composed of a guide wheel, a horizontal pusher and a push rod, and the push rod is fixed on the horizontal pusher horizontally, and the guide wheel passes through a The pin shaft of the push rod is fixed on the top push rod, and the horizontal pushing machine is fixed on the machine base through the guide groove, and a set of guide components are respectively arranged before and after the rolling components of the left rolling mechanism; the left rolling mechanism and the right The structure of the rolling mechanism is the same. When the pressure roller of the left rolling mechanism and the pressure roller of the right rolling mechanism roll the flange of the H-shaped steel, the rolling surfaces of the two pressure rollers are on the same level; A row of driving roller tables for driving H-beams is arranged below the middle position of the rolling mechanism and the right side of the rolling mechanism; the controller is respectively connected with the elevator, the horizontal pusher and the motor driving the driving roller table.

Further, the two guide wheels are located on the upper and lower sides of the push rod and fixed on the push rod.

Further, the shape of the pressure roller is one of a cylindrical structure or a spherical arc structure.

Further, the middle part of the rolling surface of the pressure roller is a cylindrical surface with the same diameter, and the middle part of the rolling surface of the pressure roller coincides with the edge of the H-shaped steel.

Further, the horizontal distance between the guide wheel and the side of the horizontal pusher is 217 mm, and the overlapping distance between the rolling surface of the pressure roller and the flange of the H-shaped steel is 60 mm.

Compared with the prior art, the utility model has the beneficial effects that: the structure of the straightening machine of the utility model is reasonable, and when the H-shaped steel is straightened, the pressure roller of the straightening machine can be fully contacted with the H-shaped steel flange to avoid The edges of the H-shaped steel flange are deformed by compression.
