Description

Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, in particular to a clamping mechanism for producing H-shaped steel. Background Art

[0002] H-beam is an economical and efficient profile with more optimized cross-sectional area distribution and 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 H-beam are arranged at right angles, H-beam has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structure weight. It has been widely used. It is an economical cross-sectional profile with a cross-sectional shape similar to the capital Latin letter H. It is also called universal steel beam, wide flange (edge) I-beam or parallel flange I-beam. The inner and outer sides of the flange of H-beam are parallel or nearly parallel, and the ends of the flanges are at right angles. In the production process of H-beam, the clamping mechanism is usually used to fix and clamp the H-beam to be processed for cutting, welding, cold bending and other processing operations. This clamping mechanism needs to have sufficient strength and stability to ensure that the position of the H-beam will not move or deform during the processing, so that the clamping mechanism is effective and reliable in the production process of H-beam, so that the processing operation can proceed smoothly and meet the expected quality requirements.

[0003] The existing clamping mechanism for H-beam production is not convenient for rapid clamping and loosening during actual use, and it is difficult for personnel to operate when producing and processing H-beam.

[0004] After searching the existing patents: a clamping mechanism for H-beam production (publication number: CN220051474U), including a base, a bracket and a first clamping plate, an H-beam body is installed on the top of the base, fixed plates are installed on both sides of the top of the base, brackets are installed on the inner side of the fixed plates, an adjustment structure is provided on one side of the bracket, and a lifting structure is provided inside the bracket, the lifting structure includes an internal thread, a screw, a movable block and a handle, the screw is installed inside the bracket, the top of the screw is installed with a handle, the outer side of the screw is installed with a movable block, and the inside of the movable block is installed with an internal thread. The utility model adjusts the distance between the first clamping plate and the second clamping plate by rotating the handle provided at the top of the bracket, rotating the screw, and the movable block drives the second clamping plate to move up and down, so that the first clamping plate and the second clamping plate can fix the edges of the H-beam body of different heights.

[0005] Although the above patent has achieved the adjustment of the distance between the first clamp and the second clamp so that the first clamp and the second clamp can fix the edges of the H-beam body of different heights, it is not convenient for positioning and transportation. When transporting the H-beam, the H-beam is prone to shaking or shifting, resulting in friction between the H-beam and the conveying equipment or other objects, causing damage.

[0006] Therefore, it is necessary to invent a clamping mechanism for H-beam production to solve the above problems. Utility Model Content

[0020] 1. The clamping mechanism used in the production of H-beams is provided with a limit assembly and a clamping block. When the H-beam needs to be clamped, the H-beam is conveyed to the rolling sleeve in an I-shape, and then the cylinder is started to contract and the tension frame is pulled, so that the two sets of clamping blocks rotate at both ends of the tension frame, and then the limit column slides in the slide groove, so that the clamping block is clamped on the surface of the H-beam.
