Definition of Bar Bender
1. General Definition
A bar bender is a mechanical tool or machine used in construction to bend reinforcing steel bars (rebar) into desired shapes and angles as specified in structural designs. It is commonly used in reinforced concrete works, where bent bars are essential for creating beams, columns, slabs, and other structural elements.
2. Main Functions
The bar bender serves several essential functions in construction:
Bending steel reinforcement bars (usually round or deformed) to specific angles or curves.
Ensuring accuracy and uniformity in bar bending.
Increasing efficiency and reducing labor time compared to manual bending.
Supporting the fabrication of rebar cages and other structural reinforcements.
3. Main Components
A typical bar bender (manual or automatic) consists of:
Bending rollers or pins: Used to guide and shape the bar during bending.
Angle selector or stop system: Sets the desired bending angle.
Electric motor or manual crank: Provides the force needed for bending.
Foot pedal or switch (in electric machines): Used to control bending motion.
Steel frame: Provides stability during operation.
