Description

Technical Field

[0001] The utility model relates to the technical field of straightening machines, in particular to an automatic feeding C-shaped steel structure straightening machine. Background Art

[0002] During transportation, or when the C-shaped steel is hoisted at the construction and installation site, it collides, or when other heavy objects press on it, it will cause the C-shaped steel to deform and bend. Therefore, the C-shaped steel needs to be corrected by a straightening machine.

[0003] For example, Chinese patent CN216705543U proposes an H-beam straightening machine, which relates to the technical field of straightening machines, including a processing table, a conveyor belt, a punching device and a straightening wheel. The conveyor belt is fixedly installed on the top of the processing table. Two punching devices are fixedly installed on the top of the processing table. One of the punching devices is internally rotatably connected with a positive and negative threaded rod. The surface of the positive and negative threaded rod is sleeved with a slider. A clamping rod is fixedly installed on one side of the slider. The slider is rectangular in shape. The inside of the slider is provided with an internal thread. The straightening wheel is sleeved on the surface of the clamping rod, and the punching device includes a support frame. In the utility model, under the cooperation of the straightening wheel and the punching machine, the straightening wheel slides inside the H-beam steel groove, thereby flattening the bent position and correcting the H-beam. In addition, when the punching machine is punching downward, it can correct H-beams of different models, thereby preventing waste of steel materials.

[0004] However, in the above-mentioned patent, the steel is corrected above the conveyor belt, which may cause damage or deformation of the conveyor belt after long-term use.

[0005] Based on this, the utility model designs an automatic feeding C-shaped steel structure straightening machine to solve the above problems. Utility Model Content

[0024] 2. When the utility model corrects the upper end of the C-shaped steel, the cylinder is started, and the output end of the cylinder drives the connecting plate to move up and down, thereby adapting to C-shaped steels of different heights. The telescopic slide rod cooperates with the cylinder to drive the connecting plate to move up and down under the limiting and guiding action of the telescopic sleeve, so that the first pressing roller always maintains a balanced position, improves the stability of the first pressing roller, and makes the contact between the first pressing roller and the C-shaped steel more uniform, thereby improving the correction effect.

[0025] 3. When the utility model is installed, the second pressing roller is placed between one of the upper and lower groups of corresponding threaded holes, the connecting rod passes through the threaded holes at the upper end, the second pressing roller and the threaded holes at the lower end in sequence, and the upper and lower ends of the connecting rod are respectively locked on the support plate by bolts. When the slide plate drives the support block to move left and right, the second pressing roller corrects the C-shaped steel, thereby realizing the correction function on the front and rear sides of the C-shaped steel, and at the same time facilitating the disassembly and maintenance of the second pressing roller. In addition, multiple groups of threaded holes can adapt to C-shaped steels of different thicknesses. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The utility model is further described below in conjunction with embodiments.

[0038] The terms “left”, “right”, “front”, “back”, “up” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0039] In some embodiments, please refer to the attached instructions. Figure 1-7 , an automatic feeding C-shaped steel structure straightening machine, comprising a frame 1;

[0040] The left and right ends of the frame 1 are respectively fixedly connected with a first conveying frame 2 and a second conveying frame 3 for loading and unloading;

[0041] The upper end of the frame 1 is fixedly connected to a support block 7 for supporting the C-shaped steel and is limitedly slidably connected to the inner side of the C-shaped steel;

[0042] The upper end of the frame 1 is connected to a first correction component 5 for correcting the upper end of the C-shaped steel;

[0044] The upper end of the frame 1 is connected to a feeding assembly 4 for automatically loading and unloading C-shaped steel; a support block 7 is connected to the feeding assembly 4;

[0045] The feeding assembly 4 includes a driving assembly, a slide plate 45, a first limiting plate 46, a first baffle plate 47, a second limiting plate 48 and a second baffle plate 49.

Since the lower end of the slide plate 45 is connected with the slide rail of the frame 1 by limited sliding, when the first correction component 5 corrects the upper end of the C-shaped steel on the slide plate 45, the frame 1 supports the slide plate 45. The slide plate 45 is used to replace the conveyor belt, thereby avoiding mechanical damage to the conveyor belt caused by extrusion. In addition, since the first correction component 5 can be raised and lowered, it can adapt to C-shaped steels of different heights, and the second correction component 6 can be adjusted front and back, so it can adapt to C-shaped steels of different thicknesses.

[0051] The support column 51 is connected to the second correction component 6;

[0052] When the upper end of the C-shaped steel is corrected, the cylinder 53 is started, and the output end of the cylinder 53 drives the connecting plate 54 to move up and down, so as to adapt to C-shaped steels of different heights. The telescopic slide rod 57 cooperates with the cylinder 53 to drive the connecting plate 54 to move up and down under the limiting guide action of the telescopic sleeve 56, so that the first pressing roller 55 always maintains a balanced position, improves the stability of the first pressing roller 55, and makes the contact between the first pressing roller 55 and the C-shaped steel more uniform, thereby improving the correction effect;

[0053] The second correction assembly 6 includes a mounting column 61, a support plate 62, a second pressure roller 63, a threaded hole 64 and a connecting rod 65.
