Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal processing, in particular to a bending device for steel structure processing. BACKGROUND

[0002] In the fields of modern architecture, mechanical manufacturing, and various infrastructure construction, steel structures have become a widely used building and engineering material due to their high strength, light weight, and convenient construction. With the rapid development of industrial technology and the increasing scale and complexity of various projects, there is an increasing demand for precision, efficiency, and diversification in steel structure processing.

[0003] In the process of steel structure processing, bending is a key and common process operation. Through bending, straight steel can be transformed into curved shapes that meet different design requirements, thereby achieving diversified arrangement and connection of steel structures in space. However, current bending devices for steel structure processing still face many challenges and problems in actual application, which to some extent limits the further development of the steel structure processing industry.

[0004] Traditional bending devices often have single functions and can only bend steel structures of specific sizes and shapes. Once encountering different sizes and materials of H-shaped steel, a large amount of time and manpower is needed to replace the mold or perform complex debugging of the equipment, which seriously affects production efficiency and makes it difficult to meet modern large-scale and high-efficiency production demands. At the same time, when bending different sizes of H-shaped steel, due to the limitations of device design, long straight head parts are easily produced at the beginning and end of bending, which not only causes waste of raw materials, increases production costs, but also reduces the overall quality of products and the utilization rate of raw materials.

[0005] In addition, existing bending devices also have deficiencies in equipment stability and maintenance. Some bending devices are prone to structural looseness and component wear during long-term high-strength operation, resulting in unstable equipment operation and decreased processing precision. Moreover, when the equipment is partially damaged, due to its overall design structure, the entire equipment often needs to be disassembled, repaired, or replaced, which not only greatly increases the cost and time cost of equipment maintenance, but also seriously affects the continuity of production, causing significant economic losses to enterprises.

[0006] In terms of automation, many bending devices still rely on a large amount of manual operation. The loading and unloading of steel materials often require the use of cranes with manual assistance, which not only makes the production process less smooth but also cannot guarantee safety, making it difficult to meet the requirements of modern production for high efficiency, precision, and automation.

[0007] Therefore, the present application designs a bending device for steel structure processing to solve the above problems. SUMMARY
