Introduction: Double Challenge of Steel Bar Processing Efficiency and Precision
In large infrastructure projects such as expressways and high-speed railways, the efficiency and accuracy of rebar processing directly affect the progress and quality of the project. Traditional single-head rebar bending equipment, due to its slow processing speed and large fluctuations in accuracy, is difficult to meet the requirements of large-scale and high-standard construction. The horizontal four-head rebar bending center, with its innovative technology such as multi-head collaborative operation and intelligent control system, has become the key equipment to solve this problem. This article will analyze how Xuhui (Shandong) Intelligent Equipment Co., Ltd. achieves efficient and accurate rebar bending processing through structural optimization and intelligent control, based on its technical practice.

Industry Technical Pain Points: Bottlenecks in Efficiency and Precision of Traditional Equipment
Traditional single-head rebar bending equipment has two major core pain points in the processing process: Firstly, it can only bend one rebar at a time, and the processing speed is limited by the head's action cycle, making it difficult to meet the needs of large-scale construction; secondly, it relies on manual operation to adjust the bending angle and position, which is greatly affected by the operator's skill level, leading to issues such as angle deviation and position shift, thereby reducing the pass rate of finished rebar products. Taking a high-speed railway project as an example, it takes 8 hours to process 1000 HRB400 rebars with a diameter of 25mm using traditional equipment, and the rework rate due to precision issues is as high as 15%, significantly increasing the project's cost and time pressure.

Introduction to Corporate Technical Strength: Xuhui Intelligent Equipment's Multi-Head Coordination and Intelligent Control Technology
Xuhui (Shandong) Intelligent Equipment Co., Ltd., as a leading enterprise in the CNC steel bar equipment field, has developed a horizontal four-head steel bar bending center to address the pain points of traditional equipment. This equipment achieves a dual enhancement of efficiency and precision through the following technologies:
Step 1: Multi-head collaboration operation, efficiency increased by 300%.
Equipped with four independent heads, capable of bending and processing four rebars simultaneously. Each head is powered by an independent servo motor, driven by a PLC control system for synchronized operation, enhancing the processing speed by 300% compared to traditional single-head equipment. Taking HRB400 rebars with a diameter of 25mm as an example, four can be processed at a time, reducing the processing time for 1000 rebars to 2 hours, and eliminating the need for frequent manual material change, significantly reducing labor intensity.
STEP 2: Intelligent Control System, Precision Error ≤0.5°
The equipment is equipped with Xuhui's independently developed intelligent control system, supporting digital input of parameters such as bending angle and position. The system monitors the machine head position in real-time through high-precision encoders, combines closed-loop control algorithms to automatically correct deviations, ensuring the bending angle accuracy error ≤0.5° and position deviation ≤1mm. In an airport project application, the qualified rate of the finished steel bars processed by the equipment reached 99.5%, a 20 percentage point increase over traditional equipment.
STEP 3: Modular design for compatibility with various reinforcement bar specifications
The equipment adopts a modular design, allowing for quick replacement of parts such as head spacing and bending molds, suitable for processing various specifications of rebars with diameters of 12-40mm and lengths up to 12 meters. Additionally, the equipment supports custom settings for parameters such as bending radius and angle, meeting the processing needs for complex shapes like highway guardrail rebars and high-speed railway sleepers.
Summary of Technical Advantages:Xuhui Horizontal Four-Machine Head Rebar Bending Center, through multi-head coordination, intelligent control, and modular design, achieves a 300% increase in processing efficiency, accuracy error ≤0.5°, and core advantages of adapting to multi-specification rebar processing, providing the construction industry with an efficient and precise rebar processing solution.
