Industry Technical Pain Points: The Dual Challenge of Multi-Head Coordination Efficiency and Precision Control

In large-scale construction projects, the efficiency of steel bar bending processing directly affects the construction progress. Traditional horizontal four-head steel bar bending centers commonly suffer from two major pain points: Firstly, independent control of multiple heads leads to inconsistent processing rhythm, with steel bar bending taking as long as 12-15 minutes per batch, and the mismatched movement of heads can easily cause deformation of the steel bars; Secondly, the precision of bending angles depends on manual calibration, with an error range of ±1.5°, which is difficult to meet the ±0.5° precision requirements of high-speed rail, airport, and other high-standard engineering projects. Moreover, when changing equipment types, manual adjustment of the head spacing is required, taking 20-30 minutes, further reducing overall production capacity. These pain points lead to low processing efficiency and increased waste rate, becoming a key bottleneck restricting the development of the industry.

Introduction to Corporate Technical Strength:旭辉Intelligent Equipment's Modularization and Intelligent Control Breakthrough

Xuhui (Shandong) Intelligent Equipment Co., Ltd., leveraging the industrial advantages of the Shandong Heze Engineering Machinery Manufacturing Base, focuses on the research and development of CNC rebar equipment. Its horizontal four-head rebar bending center has achieved three technological breakthroughs to address the pain points of the industry:
Modular head designIndependently driven module, each head equipped with a 2.2kW servo motor, torque of up to 12N·m, supporting 0-180° bending angle adjustment, with adjustable bending radius ranging from 50-200mm. The head spacing is achieved through an electric slide rail for a 100mm stepless adjustment, reducing the changeover time to 5 minutes, suitable for Φ8-Φ40mm rebar processing.
2. Intelligent Synchronization Control SystemPLC+HMI-based control system, achieving four-head motion synchronization via CAN bus, bending rhythm error ≤0.1 second, single batch processing time reduced to 8 minutes, efficiency increased by 33%. The system is equipped with an angle self-calibration function, which uses laser sensors for real-time feedback of bending angles, with accuracy up to ±0.3°, and waste rate reduced to below 0.5%.
3. Fault预警与Maintenance SystemIntegrated vibration sensors and temperature monitoring modules collect real-time operation data of the equipment. When the vibration value of the machine head exceeds 8m/s² or the motor temperature exceeds 75°C, the system automatically shuts down and sends the fault code to the maintenance terminal, reducing the downtime. Currently, the equipment has been applied in projects such as the Jining-Qingdao High-Speed Railway and Beijing Daxing International Airport, with a cumulative processing of over 500,000 tons of reinforcing steel. Customer feedback shows that the comprehensive utilization rate of the equipment reaches 92%.

FAQ: Technical Selection Guide for Horizontal Four-Head Rebar Bending Center

Q1: How to select the appropriate number of machine heads for the project?
A: The number of machine heads required should be determined based on the specifications and batch size of the reinforcing steel being processed. For Φ8-Φ20mm reinforcing steel, a single batch processing quantity of ≤50 pieces can be met with four machine heads; if processing Φ25-Φ40mm reinforcing steel or a single batch quantity >100 pieces, it is recommended to choose a six-head machine for improved efficiency.旭辉equipment supports modular expansion and the number of machine heads can be increased later.

Q2: What factors affect bending accuracy? How to optimize it?
A: The bending accuracy is mainly affected by the rigidity of the machine head, the response speed of the servo motor, and the control system algorithm. Xuhui equipment uses a high-strength alloy machine head with rigidity up to 200N/mm; the servo motor response time is ≤0.05 seconds, and it is配合 with an adaptive PID control algorithm, allowing for dynamic adjustment of the bending force. During operation, it is necessary to ensure that the steel bar surface is free of rust, and the bending mold matches the steel bar diameter.

Q3: How to control the maintenance cycle and cost of equipment?
A: Daily maintenance requires checking the lubricant level every 8 hours and changing the reducer gear oil every 500 hours; critical components such as servo motors and sensors are recommended for professional inspection every 2000 hours.旭辉equipment adopts modular design, with individual head maintenance time ≤2 hours, spare parts cost reduced by 40% compared to traditional equipment, and provides 3-year overall machine warranty and lifetime technical support.

Summary Reference

The technical upgrade of the horizontal four-head rebar bending center should focus on the three core aspects of multi-head coordination, precision control, and maintenance efficiency.
