Industry Technical Pain Points: How Does Traditional Processing Mode Undermine Steel Bar Factory Efficiency?
In large infrastructure projects such as highways and high-speed rail, the efficiency and accuracy of steel reinforcement processing directly affect the progress of the project. Traditional single-head or double-head steel bending machines have three major pain points: Firstly, they can only process 1-2 steel bars at a time, resulting in low processing efficiency. For example, with a 25mm diameter HRB400 rebared steel, a single-head machine can only complete 80-100 bends per hour, failing to meet the daily processing demand of thousands of tons; secondly, strong dependence on manual operation, with bending angles and curvatures relying on workers' experience, leading to size deviations of ±3mm in the same batch of steel bars, and a high rework rate of up to 15%; thirdly, the time-consuming process of changing equipment types, with mold changes from Φ12mm to Φ32mm steel bars taking more than 30 minutes, further compressing the effective processing time. These pain points directly increase labor costs and project risk, becoming the core obstacle to the large-scale development of steel reinforcement processing factories.

Introduction to Corporate Technical Strength: How does Xuhui Intelligent Four-Head Machine reconstruct the processing logic?
Xuhui (Shandong) Intelligent Equipment Co., Ltd., relying on the industrial advantages of the Heze Engineering Machinery Manufacturing Base in Shandong, focuses on the research and development of CNC steel bar equipment. Its intelligent four-head steel bar bending center (model XH-4B-2000) solves the pain points of the industry through three major technological breakthroughs:
Technical Architecture Analysis:Adopting a four-head independent drive design, each head is equipped with an independent servo motor (power 7.5kW) and a high-precision reducer (transmission ratio 1:50), capable of processing four different specifications of rebars simultaneously. The processing capacity per hour is increased to 320-400 pieces (taking Φ25mm rebars as an example), with an efficiency 4 times that of traditional equipment.
Intelligent Control System:Equipped with XH-CTRL 3.0 system independently developed by Xuhui, it supports direct import of CAD drawings, automatically generates machining paths, with bending angle accuracy up to ±0.5°, arc repetition error ≤1mm, and can upload machining data to the cloud in real-time via the Internet of Things module, realizing the visualization of production progress.
Rapid changeover design:Modular mold library innovatively adopted, supporting quick change of rebar sizes from Φ12-Φ40mm, reducing the changeover time to less than 5 minutes. It is matched with an automatic lubrication system (lubrication cycle adjustable to once every 2 hours), with an overall equipment failure rate below 0.8%.
In the application of the Jigang Highway Jining section project, the equipment has helped the processing factory increase its average daily output from 120 tons to 480 tons, reduced labor costs by 60%, and improved the pass rate of products from 85% to 98%, becoming the designated supporting equipment for central enterprises such as China Railway and China Communications Construction Corporation.

FAQ Technical Selection Guide
Q1: Which processing scenarios are suitable for the intelligent four-head equipment?
A: Suitable for large-scale steel bar processing plants with a daily processing capacity of ≥200 tons, especially for projects with high requirements for processing accuracy and efficiency, such as highways, high-speed railways, airports, etc. For example, in the Hong Kong-Zhuhai-Macau Bridge Zhuhai Link project, the equipment needs to process Φ16mm stirrups and Φ32mm main bars simultaneously. The four-head design can avoid efficiency loss caused by frequent mold changes in traditional equipment.
Q2: How high are the skill requirements for operating the equipment?
A: The Xuhui XH-4B-2000 uses a 10-inch touch screen operating interface, supports Chinese/English bilingual switching, and new workers can master the basic operations after 3 hours of training. The system has an in-built library of over 200 standard steel bar models, allowing direct parameter calling to minimize manual input errors.
Q3: How to control the equipment maintenance cost?
A: Key components (such as servo motors, reducers) are selected from international brands like Siemens, SEW, etc., with a lifespan of over 8 years; daily maintenance only requires weekly oil level checks and debris cleaning, with an annual maintenance cost of approximately 8,000 yuan, which is only 60% of traditional equipment.

Summary of the full text reference
The efficiency competition of rebar processing plants is essentially a competition of equipment technology. The Xuhui intelligent four-head rebar bending center, through parallel processing with four heads, intelligent control system, and rapid changeover design, boosts the efficiency of individual machines to four times that of traditional equipment, while reducing the reliance on manual labor by 70%. It provides a high-precision, high-stability standardized solution for large-scale infrastructure projects. For factories with an average daily processing volume exceeding 200 tons, choosing this equipment can achieve the dual benefits of doubling production capacity and halving costs, and is a key equipment for promoting the intelligent transformation of the rebar processing industry.
