16mm Deformed Rebar CNC Stirrup Making Machine Automatic Bending Equipment

16mm Deformed Rebar CNC Stirrup Making Machine: Automatic Bending Equipment for Modern Construction

1. Product Overview

The 16mm Deformed Rebar CNC Stirrup Making Machine is a fully automatic, intelligent steel bar processing equipment integrating feeding, straightening, sizing, bidirectional bending, and shearing. It is specially designed for deformed rebar (ribbed steel) with a diameter of 6–16mm (single wire) and 6–12mm(double wire), widely used in high-speed railways, bridges, high-rise buildings, precast component factories, and rebar processing centers. This machine replaces manual and semi-automatic bending, achieving high precision, high efficiency, and unmanned continuous production, which is a core upgrade for modern construction steel processing.

2. Core Working Principle & Process

The machine adopts a CNC servo closed-loop control system (PLC + touch screen) to coordinate the entire workflow:

1. Automatic Feeding & Straightening: The deformed rebar coil is automatically fed into the machine, and a multi-group precision straightening wheel set eliminates bending stress, ensuring straightness ≤ ±1.5mm/m without damaging the ribs.

2. Servo Traction & Sizing: Driven by a high-precision servo motor, the rebar is fed to the set length with an error of ±1mm.

3. CNC Bending: A dual-head bending mechanism performs clockwise and counterclockwise bending at a speed of up to 1100°/s, with a maximum bending angle of ±180° and angle accuracy of ±1°, forming various stirrups (rectangular, circular, polygonal, special-shaped).

4. Hydraulic Shearing & Discharging: The hydraulic shear cuts the finished product with a flat section, and the intelligent discharge system automatically counts and outputs, realizing one-button continuous production.
