It perfectly solves the processing pain points of large-diameter round steel bars such as difficult manual forming, low dimensional accuracy and low production efficiency. This paper comprehensively introduces the structural design, core technical advantages, performance parameters and engineering application value of the 18mm round steel bar dedicated CNC stirrup bending machine, providing a professional reference for steel bar processing in construction, highway, railway and precast component projects.
1. Product Overview
The 18mm round steel bar intelligent CNC stirrup bending machine is a high-power, heavy-duty rebar forming equipment independently optimized and designed for large-diameter round steel processing scenarios. Different from ordinary small-diameter stirrup bending equipment, this machine is specially calibrated and strengthened for the mechanical characteristics of 18mm round steel bars, which have high hardness and strong tensile resistance. It supports one-time automatic processing of round steel bars with a diameter range of 6mm to 18mm, and can stably complete straightening, multi-angle bending, fixed-length cutting and forming of 18mm large-diameter round steel bars in a single process.
Equipped with an industrial PLC CNC intelligent control system and high-sensitivity touch screen operation terminal, the equipment realizes full-process automated operation without manual intervention. It can process various specifications of stirrups, polygonal steel frames, arc-shaped hoops and special-shaped reinforcement components, covering almost all conventional and special-shaped steel bar forming requirements in engineering construction. Widely applicable to on-site steel bar processing of large construction sites, professional rebar processing factories, precast component workshops, highway and railway infrastructure projects.
2. Core Structural Design & Pracovní princip
2.1 Optimized Mechanical Structure
The whole machine adopts a thickened welded steel frame structure, which has high rigidity and strong shock resistance, effectively avoiding machine body vibration and dimensional deviation during high-load bending of 18mm large-diameter round steel bars. The key bending components adopt high-strength alloy steel forging and overall heat treatment process, which greatly improves wear resistance and pressure resistance, and adapts to long-term high-intensity processing of large-diameter steel bars.
The equipment is equipped with a multi-head synchronous bending mechanism (five-head optional), which can realize synchronous or sequential multi-point bending. Compared with single-head bending equipment, it effectively improves the forming efficiency of large-size stirrups. The sliding fixed-length cutting tool is made of high-hardness tool steel, which ensures flat and burr-free cutting sections of 18mm round steel bars and avoids material waste caused by irregular cutting.
2.2 Intelligent Working Principle
Based on CNC digital programming technology, the equipment first inputs the required stirrup size, úhel ohybu, processing quantity and other parameters through the touch screen. The industrial PLC controller automatically calculates the processing trajectory and transmits the instructions to the servo drive system. The automatic feeding mechanism accurately sends the round steel bar to the straightening system to eliminate steel bar bending and torsion deformation. Pak, the bending mechanism completes precise angle forming according to the programmed parameters, and finally the cutting system realizes fixed-length blanking. The whole process realizes closed-loop intelligent control, with automatic error correction and parameter memory functions.

3.1 High Precision for Large-Diameter Steel Processing
Aiming at the problem that 18mm round steel bars are easy to rebound and deform during bending, the equipment is equipped with an intelligent rebound compensation algorithm. The bending angle error is controlled within ±0.5°, and the stirrup side length precision is accurate to ±1mm. It completely avoids the quality problems of unqualified steel bar size and inconsistent forming effect caused by manual processing and ordinary mechanical bending, and meets the high-precision construction standards of national key infrastructure projects.
3.2 High Processing Efficiency & Labor Saving
The full-automatic integrated design realizes one-stop processing of feeding, rovnání, ohýbání a řezání. The processing speed is automatically matched and adjusted synchronously, without manual auxiliary positioning and measuring. A single device can replace 4-6 manual workers, which reduces labor costs by more than 60%. It can continuously process 18mm round steel stirrups in batches, with stable hourly output and no need for frequent shutdown debugging, greatly improving the overall progress of steel bar processing projects.
3.3 Simple Operation & Strong Compatibility
The humanized touch screen operation interface is simple and intuitive, similar to intelligent mobile phone operation. Ordinary workers can master the operation skills after simple training. The system can store more than 100 sets of conventional stirrup processing programs, realizing one-click switching of different specifications without repeated programming. In addition to processing 18mm round steel bars, it is compatible with the processing of 6-16mm round steel bars and 8-16mm threaded steel bars, with diverse processing shapes, including square, obdélníkový, triangular, circular and special-shaped polygonal stirrups.
3.4 Stabilní výkon & Low Maintenance Cost
The whole machine is driven by high-power professional motor and matched with stable hydraulic and servo control system. It has strong power reserve and can operate stably for a long time under high-load working conditions. The core components have excellent wear resistance and fatigue resistance, with low failure rate and long service life. The modular structural design is convenient for daily maintenance and parts replacement, effectively reducing later operation and maintenance costs and equipment downtime.
