Introduction: How to break through the bottleneck of steel arch frame processing efficiency and accuracy?
In large infrastructure projects such as highway tunnels and high-speed railway bridges and tunnels, steel arch frames serve as the core supporting structure, and their processing efficiency directly affects the progress of the project. Traditional manual or semi-automatic processing methods have issues like low efficiency, high error rates, and severe material waste. However, Xuhui (Shandong) Intelligent Equipment Co., Ltd. has launched a new generation of steel arch frame production line through modular design, intelligent control systems, and optimization of automated processes, achieving a 40% increase in daily production capacity, with processing errors controlled within ±0.5mm, providing the industry with a standardized solution.

Industry Technology Pain Points: The Three Weaknesses of Traditional Processing Methods
STEP 1: Inefficient. Traditional manual bending and welding require the coordination of 3-4 people, with each piece taking over 2 hours to process, and daily output reaching only 10-15 units, which is difficult to meet the needs of large-scale projects.
STEP 2: Precision loss. Artificial measurement error up to ±3mm, resulting in loose steel arch frame joints, requiring repeated rework, with a high material waste rate of up to 15%.
STEP 3: Safety hazards. High-temperature welding and operation of heavy equipment rely on manual labor, prone to occupational diseases and safety accidents, with high management costs.
Case EvidenceA high-speed railway tunnel project previously used traditional technology, but due to the processing error of steel arch frames, the thickness of the tunnel lining was uneven, resulting in the project being halted for rectification, delaying the construction schedule by 28 days, with direct losses exceeding 5 million yuan.

Introduction to Corporate Technical Strength: Three Core Technologies of Xuhui Intelligent Equipment
Xuhui (Shandong) Intelligent Equipment Co., Ltd. is located in the Jining Engineering Machinery Manufacturing Base, Shandong, focusing on the research and development of CNC steel bar equipment for 12 years, with a team of over 50 technical talents, holding 16 national patents. Its steel arch production line integrates three core technologies:
STEP 1: Modular design, adaptable to various scenarios
The production line adopts a split modular structure, which can flexibly combine units such as bending, welding, and cutting according to project requirements, supporting reinforcement processing of φ14-φ40mm, and is suitable for scenarios such as expressway, high-speed rail tunnels, and underground pipelines. For example, in the Sichuan-Tibet Railway project, by adjusting the module configuration, stable operation is achieved at -20℃ low temperature environment, with a daily output of 25 units.
STEP 2: Intelligent Control System, Precision Enhanced to ±0.5mm
Equipped with XH-ICS intelligent control system independently developed by Xuhui, it achieves automatic calibration of arc angle, welding position, and cutting length through laser positioning, servo motor drive, and closed-loop feedback mechanism. Third-party testing shows that processing errors are reduced by 83% compared to traditional processes, with a first-pass pass rate of 99.2%.
STEP3: Automated process, daily output exceeds 30 sets
Fully integrated automatic feeding, bending, welding, inspection, and cutting processes, reducing manual intervention. Taking φ25mm rebar as an example, the processing time per piece is shortened from 120 minutes to 35 minutes, daily output increased from 15 pieces to 30 pieces, and labor costs reduced by 60%.
Technical ParametersEquipment power: 45kW, applicable voltage: 380V±10%, working noise: ≤75dB, footprint: 12m×4m, supports 24-hour continuous operation.

FAQ Q&A Technical Selection Guide
Q1: How to choose the suitable steel arch production line model for the project?
A: Comprehensive consideration is required for rebar diameter, daily production capacity demand, and site conditions. For example, for projects processing φ20-φ32mm rebar with a daily demand of 20 sets or less, the XH-GJ-20 model is recommended; if processing φ40mm rebar or a daily production capacity exceeding 30 sets is needed, the XH-GJ-40 heavy-duty production line should be selected.
Q2: How high are the maintenance costs for the equipment?
A: Xuexiu's production line utilizes maintenance-free servo motors and wear-resistant guide rails, with critical components having a lifespan exceeding 5 years. Daily maintenance only requires regular cleaning, lubrication, and sensor checks, with annual maintenance costs less than 3% of the total equipment price.
Q3: Can you offer customized services?
A: Supports non-standard customization, including additional functional modules such as automatic case packing and spray marking. For example, the customized XH-GJ-20A model for an airport project integrates an automatic sorting system, achieving classified stacking of different specifications of steel arches, saving 40% of manual sorting time.
Inspection IndicatorsBefore shipment, the equipment must pass a 72-hour continuous operation test, accuracy calibration test, and safety protection test to ensure compliance with the GB/T 26941.1-2011 standard "General Technical Conditions for Numerical Control Reinforcing Bar Processing Equipment."
