Description

Technical Field

[0001] The utility model relates to the technical field of building steel materials, in particular to a bending device for building steel materials. Background Art

[0002] Construction steel can usually be divided into steel for steel structure and steel bars for reinforced concrete structure. Steel for steel structure mainly includes ordinary carbon structural steel and low alloy structural steel. The varieties include steel sections, steel pipes and steel bars. Among the steel sections, there are angle steel, I-beam and channel steel. Construction steel often needs to be bent into a certain angle according to the needs of use. Now a bending equipment for construction steel is mostly used.

[0003] The utility model patent with the publication (announcement) number: CN217798260U solves the problem that when workers use a traditional bending equipment for construction steel, they mostly need to manually lift the construction steel from the ground to the top surface of the equipment body. Since the dead weight of the construction steel is generally large, this process will consume more physical strength of the workers. When working continuously, the labor intensity of the workers is large, which brings inconvenience to the workers in using a bending equipment for construction steel with labor saving. When it is used, the worker places the next batch of construction steel to be bent on the lifting frame, and then starts the servo motor to drive the threaded rod shaft to rotate, which can drive the lifting plate to rise along the direction of the guide slide bar and the guide slide groove, so that the construction steel placed on the lifting frame can be lifted. At this time, the worker moves the lifted construction steel to the top surface of the equipment body. This method has a simple structure, but in actual operation, workers are still required to put or take out the steel from the lifting frame. This process still requires workers to carry the steel, so that this method still requires a lot of manpower. Utility Model Content
