Description

The present invention relates to the technical field of reinforcing bar bending, and particularly to a reinforcing bar bending machine.

Reinforcing bars refer to steel materials for reinforced concrete and prestressed reinforced concrete, the cross section of which is circular and may be square with rounded corners, including smooth reinforcing bars, ribbed reinforcing bars and twisted reinforcing bars. Reinforced concrete reinforcing bars refer to straight or coiled steel materials used to reinforce reinforced concrete, and are divided into two types: smooth reinforcing bars and deformed reinforcing bars, and the delivery status is two types: linear and coiled. And the smooth rebar is actually small round steel and coiled round steel, which are usually low carbon steels. The deformed reinforcing bar is a reinforcing bar having ribs on its surface, and usually has two vertical ribs and horizontal ribs evenly distributed along the length direction. There are three types of horizontal ribs: spiral, glyph, and crescent. It is represented in millimeters of nominal diameter.
