Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a curved beam bending device for processing steel structures. Background Art

[0002] Steel structures are made of steel and are one of the main types of building structures. They primarily consist of components such as beams, columns, and trusses, made from sections and plates. Rust removal and prevention processes include silanization, pure manganese phosphating, water washing and drying, and galvanizing. Components are typically connected using welds, bolts, or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, high-rise buildings, bridges, and other fields.

[0003] Special-shaped beams are beam structures with non-rectangular cross-sections in construction projects. Typical forms include rainbow beams, curved beams, T-beams, and L-beams. Among them, curved beams, also known as curved steel beams, have an arc-shaped cross-section and can withstand large bending moments and shear forces, making them particularly suitable for large-span and curved steel structures. Due to the special shape of the curved beam, its stress state is more complex, and multiple stress states such as bending moments, shear forces, and torques need to be considered. In terms of processing, the manufacturing process of curved beams is relatively complex, requiring special processes such as bending and welding. In addition, the construction is difficult and requires high construction technology and equipment. The curvature and support points of the beam also need to be considered during the installation process, which is a relatively complicated process.

[0004] In existing technology, curved steel beams are formed by bending straight steel beams. Conventional press brakes consist of a machine tool, transmission mechanism, mold, and clamping mechanism. The bed is constructed of a welded channel steel spindle frame, with the upper and lower spindle bearing plates mounted within the frame using thick steel plates to ensure structural stability. The transmission mechanism, consisting of a cylinder, rack, gears, and drive shaft, converts hydraulic energy into mechanical energy, driving the various components of the press brake. The mold is a plastic component manufactured based on the profile shape and processing direction, typically made of bearing steel or roll steel and heat-treated to a hardness of at least HRC50. The clamping mechanism consists of a slide, rocker arm, and hydraulic cylinder. The cylinder's expansion and contraction drive the rocker arm to clamp and release the profile. This typical press brake structure leaves room for improvement in bending efficiency. Especially for high-hardness, large-curvature processing scenarios, the yield rate of this type of press brake is low, making it difficult to meet process requirements. Furthermore, this type of press brake can only achieve mechanical bending and cannot integrate subsequent processes such as cutting and welding. Summary of the Invention
