Description

Technical Field

[0001] The utility model relates to the technical field of construction tools, in particular to a steel bar bending machine. Background Art

[0002] Rebar bending machine is one of the rebar processing machines. The working mechanism is a horizontal turntable rotating on a vertical axis. The center pin and the bending pin are installed on the horizontal turntable. When the disc rotates, the rebar is bent. When bending the rebar, the rebar is placed between the center pin and the bending pin, and the other end of the rebar is also against the support pin or support block, which is set on the frame of the bending machine. However, due to the inconsistent diameters of the bent rebars, it is necessary to pad the support pin or support block with a steel plate of corresponding thickness during processing. This processing method has the following shortcomings: First, the thickness of the pad steel plate is difficult to control, which affects the efficiency of rebar bending; second, the pad steel plate is easy to fly out, which poses a safety hazard.
