Description

Technical Field

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

[0002] Construction machinery is a general term for mechanical equipment used in engineering construction and urban and rural construction. It consists of various machines such as excavators, earth-moving machinery, compaction machinery, engineering lifting machinery, pile-driving machinery, road machinery, concrete machinery, concrete products machinery, steel-grade prestressed machinery, decoration machinery and aerial work machinery. The construction rebar bending machine, as one of the auxiliary equipment, is also very important. When the current bending machine bends the steel bar 90 degrees, it mostly uses the edge of the workbench to bend it. The workbench will be subjected to greater extrusion, which will cause damage to the edge of the workbench for a long time, affecting the effect of the steel bar bending. The existing bending equipment cannot support the bending position when bending the steel bar. Therefore, we propose a bending equipment for construction engineering. Utility Model Content
