Description

Technical Field

[0001] This utility model relates to the field of rebar bending technology, and in particular to a rebar bending machine. Background Technology

[0002] Steel reinforcement is the skeleton of modern buildings. As the core load-bearing material of concrete structures, it uses steel as the base material and is formed into a smooth or ribbed surface through rolling process. It is tightly bonded to the concrete and has become the first choice for key parts of beams and columns. The bottom reinforcement of beams resists bending tension, the column reinforcement assists in resisting compression and improves seismic ductility, and the floor slab distribution reinforcement prevents cracking. Steel reinforcement builds the load-bearing skeleton of buildings. From the floor slabs of residential buildings to the box girders of cross-river bridges, from subway tunnels to super high-rise buildings, it is an indispensable cornerstone of modern infrastructure.

[0003] A search revealed Chinese Patent Publication No. CN218080133U, which discloses a rebar bending machine, relating to the field of rebar processing technology. The machine includes an operating table, a working disc, and a backing plate. Both the working disc and the backing plate are connected to the top wall of the operating table. A placement groove for placing rebars is connected to the side wall of the backing plate near the working disc. Before bending the rebars, they are placed in the placement groove, and then the machine is turned on to bend them. The placement groove ensures that the axis of the rebar is perpendicular to the axis of the bending shaft, thus ensuring that the processed rebars meet the processing requirements. However, this structure cannot process some bent rebars intended for reuse. Utility Model Content
