Industry Technical Pain Points: The Efficiency and Precision Dilemma of Traditional Reinforcement Bar Bending Equipment
In large infrastructure projects such as highways and high-speed railways, the efficiency and accuracy of steel bar processing directly affect the progress of the project and the safety of the structure. Traditional single-head or double-head steel bar bending equipment has three main pain points: First, each processing can only complete 1-2 steel bars, with a daily output not exceeding 500 bars, failing to meet the average daily demand of a thousand tons of steel bars; second, manual operation relies on experience, and bending angle errors often exceed ±1°, resulting in steel bars not being accurately aligned; third, the equipment changeover takes up to 30 minutes, failing to meet the fast switching requirements for steel bars of different specifications. Taking a high-speed railway project as an example, the rework rate reached 15% due to insufficient bending accuracy, directly increasing the cost by over 2 million yuan. Additionally, traditional equipment has high energy consumption and loud noise, not conforming to green construction standards, further limiting its application in modern engineering.

Introduction to Corporate Technical Strength: Core Breakthrough of Xuhui Intelligent Four-Head Reinforcement Bending Center
Xuhui (Shandong) Intelligent Equipment Co., Ltd., leveraging the industrial advantages of the Shandong Heze Construction Machinery Manufacturing Base, focuses on the research and development of CNC steel bar equipment. Its intelligent four-head steel bar bending center solves the pain points of the industry through three major technological innovations:
STEP 1: Modular four-head designIndependently driven four-head structure, capable of simultaneously bending 4 rebars in one go, paired with a 12kW high-power servo motor, daily production capacity can be increased to over 2000 rebars, a 300% improvement over traditional equipment. For instance, in the expansion project of Jining-Guangzhou Expressway, the equipment processed 18 tons of rebars in a single day, meeting the demand for a 3-kilometer section.
STEP 2: Intelligent Control AlgorithmIntegrated PLC+touch screen control system, supporting digital input of parameters such as bending angle, speed, and pause time, with error control within ±0.5°. With pre-set 20 standard bending templates, the changeover time is shortened to 5 minutes, compatible with various specifications of rebar from Φ12 to Φ40mm.
Step 3: Energy-saving and noise reduction technologyUsing variable frequency speed regulation technology, no-load power consumption is reduced by 40%; optimized gear transmission structure reduces noise from 85dB to 65dB, meeting EU CE certification standards. Currently, the equipment has served more than 30 national projects including the Hong Kong-Zhuhai-Macau Bridge and Xiong'an New Area, with a customer re-purchase rate exceeding 85%.

FAQ: Technical Selection Guide for Intelligent Four-Head Reinforcing Bar Bending Center
Q1: How to select the suitable bending center specification for the project requirements?
A: It is necessary to consider the steel bar diameter, bending radius, and daily production capacity requirements. For example, when processing Φ32mm steel bars, it is recommended to choose equipment with a bending radius of ≥8 times the diameter (i.e., 256mm); if the daily demand exceeds 1500 bars, prioritize the four-head model. Xuhui equipment supports the processing of steel bars with a diameter range of Φ12-Φ40mm, a bending radius range of 150-500mm, which can cover more than 90% of engineering scenarios.
Q2: What is the difference between an intelligent control system and a conventional PLC control?
A: Traditional PLC control only supports basic parameter settings, while Xuhui intelligent system integrates angle compensation algorithm, which can automatically correct the angle deviation caused by the elastic deformation of steel bars. For example, when bending Φ25mm steel bars to 90°, the system will monitor the actual angle in real-time through sensors and finely adjust the motor speed to ensure accuracy meets the standard.
Q3: How high are the maintenance costs for the equipment? How can the service life be extended?
A: Xuhui equipment features modular design, with critical components (such as servo motors, reducers) having a lifespan exceeding 50,000 hours. Routine maintenance involves regular lubrication of gears (every 500 hours) and debris cleaning. The company offers a 3-year warranty, with a core component failure rate below 0.5% and an overall maintenance cost 30% lower than similar products.
