Description

Technical Field

[0001] The utility model belongs to the technical field of steel bars, in particular to a double-head steel bar bending machine. Background Art

[0002] Rebar is a metal material used to reinforce concrete structures, usually in the form of long round strips. In the fields of construction and engineering, rebar is often mixed into concrete to improve its tensile strength and durability. During the processing of rebar, bending machines are required. Bending machines include double-head bending machines. Double-head rebar bending machines are a type of equipment used to process rebars. They are mainly used to bend rebars in construction to meet the needs of rebars of different shapes.
