Description

Technical Field

[0001] The utility model relates to the technical field of H-shaped steel, in particular to an H-shaped steel flange correction mechanism. Background Art

[0002] H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost savings and light structural weight. It has been widely used. The flange part of the H-shaped steel is prone to bending during the processing, which affects its use. At this time, a straightening machine is needed to correct it.

[0003] The H-beam flange straightening machine in the prior art usually uses a roller or a pressure plate to apply a correction pressure to the H-beam flange for correction. During the H-beam forming process, some granular impurities may adhere to its surface. When the roller or the pressure plate is extruded and corrected, these impurities may be pressed into the surface of the flange plate and cause the surface of the flange plate to dent. An H-beam flange straightening machine with Chinese patent publication number CN116586461A drives multiple fixed square cylinders on opposite sides to approach each other to gradually contact the non-welded side of the H-beam flange plate. The guide roller and the push scraper first abut against the non-welded side of the flange plate. As they get closer, the guide roller pulls to force multiple rotating plates to rotate with the corresponding slip rings as the center of the circle, so that the rotating plates in symmetrical positions move away from each other. During the process, the push scraper abuts against the non-welded side of the flange plate and moves away from each other synchronously, thereby pushing and scraping the impurity particles on the surface of the non-welded side of the flange plate to the non-contact surfaces on both sides to remove impurities. However, most of the existing H-beams are straightened during transportation. In this solution, the fixed cylinder needs to be driven downward for cleaning and straightening after the H-beam stops intermittently, which has certain limitations. Utility Model Content

[0004] The utility model provides an H-shaped steel flange correction mechanism to solve the above problem.

[0005] The utility model adopts the following technical scheme: an H-beam flange correction mechanism, comprising a frame arranged in front and back; a conveying device is arranged on the frame; a mounting frame is arranged on the upper end of the frame so as to move up and down; a correction device is arranged on the mounting frame; the correction device comprises a positioning assembly, a correction roller, and a cleaning assembly; the positioning assembly is used to prevent the H-beam from deflecting during movement; the correction roller is rotatably mounted on the mounting frame;

[0006] The cleaning assembly includes a cleaning structure, a shoveling structure, and a transmission structure; the cleaning structure includes a cleaning roller; the cleaning roller is arranged in front of the correction roller and is rotatably mounted on the mounting frame; elastic cleaning bristles are arranged on the side wall of the cleaning roller; the transmission structure is used to drive the cleaning roller to rotate during the rolling of the correction roller along the flange of the H-beam, and the rotation direction of the cleaning roller is opposite to that of the correction roller, so that the cleaning roller can clean the impurities on the surface of the flange of the H-beam in the direction opposite to the traveling direction of the H-beam, and drive the granular impurities away from the correction roller when the correction roller squeezes the flange of the H-beam; the cleaning shoveling structure is arranged in front of the cleaning roller, and is used to strike and shovel away the impurities adhering to the surface of the flange of the H-beam in front of the cleaning roller when the cleaning roller is cleaning.

When in use, the correction roller drives the first transmission wheel to rotate clockwise, the first transmission wheel drives the second transmission wheel to rotate counterclockwise through the first intermediate wheel and the second intermediate wheel, and the second transmission wheel drives the cleaning roller to rotate counterclockwise, so that the correction roller and the cleaning roller rotate in opposite directions.

[0008] Furthermore, the cleaning hairs are arranged in a spiral shape, which is used to push the granular impurities to both sides of the H-beam flange, avoid the accumulation of impurities on the surface of the H-beam flange, and reduce the resistance of subsequent cleaning.

[0009] Furthermore, the shovel cleaning structure includes a movable plate and a shovel plate; the movable plate is arranged on the mounting frame for movement forward and backward; the lower end of the shovel plate is wedge-shaped and is arranged at the lower end of the movable plate for movement up and down; a spring is connected between the shovel plate and the movable plate; a horizontally arranged driving rod is fixed to the upper end of the movable plate; the end of the driving rod close to the first transmission wheel is rack-shaped; a horizontally arranged spring is connected between the driving rod and the mounting frame; a rotating rod is provided on one side of the correction roller; a rotating wheel is fixed on the rotating rod; the rotating wheel is meshed with the first transmission wheel; mating wheels are fixed at both ends of the rotating wheel shaft; the mating wheel is provided with meshing positions and release positions of the rack end of the driving rod alternately along the circumference of the mating wheel; and meshing teeth are provided at the meshing position. When in use, the correction roller drives the first transmission wheel to rotate, and the first transmission wheel drives the matching wheel to rotate through the rotating wheel, and the matching wheel drives the meshing teeth and the driving rod to engage, driving the driving rod to move with the H-beam to compress the spring to accumulate force.

When the H-beam flange contacts the correction roller, the auxiliary motor is stopped, and the H-beam flange drives the correction roller to rotate through friction resistance.

[0012] The beneficial effect is: when the H-beam is moving, in the process of the correction roller rolling along the H-beam flange, the transmission structure drives the cleaning roller to rotate, and the rotation direction of the cleaning roller is opposite to that of the correction roller, so that the cleaning roller can clean the impurities on the surface of the H-beam flange in the direction opposite to the moving direction of the H-beam, and drive the granular impurities away from the correction roller when the correction roller squeezes the H-beam flange. At the same time, when the cleaning roller is cleaning, the cleaning structure strikes and removes the impurities adhering to the surface of the H-beam flange in front of the cleaning roller, thereby improving the correction effect of the H-beam flange.
