Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure processing, and in particular relates to a construction steel structure processing and bending device. Background Art

[0002] Steel structures are mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates. In steel structures, each component or part is connected by welds, bolts or rivets. Steel structures have the characteristics of high strength, light weight, strong deformability, good toughness and high reliability. The application of steel structures in construction projects can effectively improve the performance of construction projects and save construction project costs. Replacing concrete structures with steel structures can reduce the use of sand, stone and cement, and reduce the damage to non-renewable resources.

[0003] Application No. 202123379698.7 provides a bending device for processing steel structures for construction. Through the setting of two adjustable bending columns and the setting of a rotating mechanism, it can automatically bend steel structures of different specifications, avoid manual work by workers, effectively reduce the labor intensity of workers, and improve work efficiency at the same time; by driving the guide screw to rotate by a driving motor, it can drive the push plate to move, and the push plate pushes the steel structure to move, so that the position of the steel structure can be automatically adjusted according to the bending requirements, which is more convenient to use. The limit plate is driven to move by a hydraulic cylinder so that the limit plate fits at both ends of the steel structure, and the position of the steel structure can be fixed, avoiding the displacement of the steel structure during the bending process, and ensuring the bending accuracy. The bending device for processing steel structures for construction can not only automatically bend steel structures of different specifications, but also automatically push the steel structure to move;

[0004] However, when the device bends the workpiece, it is necessary to bend the workpiece by rotating the bending column, but the device cannot bend the workpiece to 90 degrees. When the bending column rotates 90 degrees, the bending column overlaps the workpiece, which will affect the unbent part of the workpiece; and the device clamps the workpiece on both sides, which can easily cause the workpiece to slide up and down or rotate during the bending process, and its practicality is poor.
