Description

Technical Field

[0001] The utility model relates to the technical field of H-shaped steel structures, in particular to a manufacturing tooling for H-shaped steel structures. Background Art

[0002] The H-shaped steel, with its unique H-shaped cross-section design, has become a key material in the modern construction and industrial fields. This design not only optimizes the cross-sectional area distribution, making the strength-to-weight ratio of the material more reasonable, but also significantly improves the tensile strength and yield strength of the steel. The inner and outer sides of the flange of the H-shaped steel are parallel or nearly parallel, and the flange end is at a right angle. This structural feature enables it to have excellent bending resistance in all directions. With the progress of technology and the improvement of steel smelting technology, the production of H-shaped steel has gradually achieved large-scale and standardization. Especially in large structures such as bridges, high-rise buildings, and factories, the H-shaped steel plays a key role with its high strength, high stiffness, and good seismic performance.

[0003] The manufacturing of H-shaped steel is mainly achieved by precisely welding three plates - two flange plates and one web plate. In this process, welding technologies such as submerged arc welding and high-frequency welding play a key role. In the submerged arc welding process, the steel plates are automatically slit, precisely assembled, and then welded with high precision by a submerged arc welding machine. Subsequently, through strict flaw detection, precise correction of the flange and web, and fine processes such as end face machining, a high-precision and high-quality H-shaped steel product is finally produced. This manufacturing method not only ensures the dimensional accuracy and weld quality of the H-shaped steel, but also enables the product to be flexibly designed and combined according to the actual engineering requirements, thus meeting the diverse building and industrial application needs. Through advanced welding technologies and precise manufacturing processes, the H-shaped steel, with its high strength, high precision, and high adaptability, has become an indispensable important material in the modern construction and industrial fields.

[0004] In the existing H-shaped steel manufacturing process, the first step is to precisely weld a flange plate to the web. After the preliminary welding is completed, it is necessary to carefully flip the semi-finished product using a mechanical jib so that the other end of the web can be closely attached to another flange plate for subsequent welding work. In this process, to ensure the accuracy of welding and the stability of the product, precise positioning of the semi-finished product is necessary. However, there is a significant problem in the existing manufacturing process: it is necessary to repeatedly use the mechanical jib to flip the steel plate to achieve the welding of both ends of the web to the flange plate. This multiple flipping operation not only takes time and effort but also poses a safety hazard of dropping. In addition, the finished H-shaped steel after welding needs to be placed above the workbench, and it again relies on the mechanical jib to safely remove it, which also increases the complexity and risk of the operation. Overall, the current H-shaped steel manufacturing process still needs to be optimized to reduce repetitive labor, improve efficiency, and ensure operation safety. Content of the Utility Model
