Industry Technical Pain Points: The Efficiency and Precision Dilemma of Traditional Small导管 Processing
In infrastructure projects such as highways and high-speed railways, small conduits, as the core components of tunnel support, directly affect the safety of the project and the construction progress with their processing quality. Traditional processing methods rely on manual operations and have three major pain points: Firstly, low efficiency, as the processing of a single conduit requires multiple steps such as cutting, bending, and welding, which takes 15-20 minutes per conduit and is difficult to achieve mass production; secondly, insufficient accuracy, where manual measurement errors can lead to deviation of conduit bending angles exceeding ±1° and welding position offsets exceeding 2mm, affecting the stability of the support structure; thirdly, high costs, as manual operations require 3-5 skilled workers and material waste rates reach 8%-10%, with comprehensive costs 30% higher than automated processing. Additionally, traditional equipment lacks data traceability functions, making it difficult to meet the modern engineering requirements for quality traceability.

Introduction to Corporate Technical Strength: Xuhui Intelligent Equipment's Automation Solutions
Xuhui (Shandong) Intelligent Equipment Co., Ltd., as an innovative enterprise in the numerical control reinforcing bar equipment field, relies on the industrial advantages of the Heze Engineering Machinery Manufacturing Base in Shandong, focusing on the research and production of equipment such as steel arch production lines and fully automatic small conduit production lines. The fully automatic small conduit production line adopts the 'three-axis linkage + intelligent control' technology architecture, with core advantages体现在 three aspects: Firstly, high-efficiency processing, through integrated design of CNC cutting, automatic bending, and laser welding, the processing time of a single conduit is shortened to within 3 minutes, with a daily output of up to 400-500 pieces, a 5-8 times increase compared to the traditional method; secondly, high-precision control, equipped with high-precision servo motors and closed-loop feedback systems, the bending angle error is controlled within ±0.5°, and the welding position offset ≤1mm, meeting the requirements of JT/T 529-2018 "Technical Specifications for the Construction of Highway Tunnels"; thirdly, intelligent management, integrated with MES production management system, which can monitor the equipment operation status in real time, record processing parameters, and generate quality traceability reports, supporting seamless connection with engineering ERP systems. Currently, this equipment has served key national projects such as the Chengdu-Tibet Railway and the Hong Kong-Zhuhai-Macau Bridge, with a cumulative delivery of over 200 units, and customer feedback on failure rate is less than 0.5%, material utilization rate has increased to over 95%.

FAQ: Technical Selection Guide
Q1: What is the core difference between the fully automatic small tube production line and the semi-automatic equipment?
A: Fully automatic equipment integrates cutting, bending, and welding processes, achieving 'one-button start and full automation' operation, while semi-automatic equipment requires manual intervention in process transitions, resulting in a significant efficiency difference. Taking Xuhui equipment as an example, its fully automatic production line is three times more efficient than the semi-automatic one, with a 60% reduction in labor costs. Moreover, fully automatic equipment uses closed-loop control technology, with better precision and stability than the open-loop control of semi-automatic equipment, especially suitable for bridge and tunnel projects with stringent quality requirements.
Q2: How to select the equipment specifications that match the project requirements?
A: Three parameters require attention: Firstly, the tube diameter range, conventional equipment supports processing of tubes with a diameter of Φ42-Φ108mm, and if the project requires handling tubes with larger diameters, a customized model must be selected; secondly, the bending radius, the minimum bending radius of the equipment should be ≤ 3 times the diameter of the tube to ensure reasonable force distribution in the supporting structure; thirdly, power configuration, equipment with a daily output capacity of over 400 tubes needs to be equipped with a main motor of ≥30kW to avoid malfunctions caused by long-term high-load operation.旭辉 equipment offers full specification coverage from Φ42-Φ159mm and supports modular customization of parameters such as bending radius and power.
Q3: What are the key points of equipment maintenance and after-sales service?
A: The maintenance of CNC equipment should focus on three major systems: Firstly, the hydraulic system, which requires regular checks for oil path cleanliness and pressure stability; it is recommended to change the hydraulic oil every 500 hours. Secondly, the electrical system, which needs to prevent dust and humid environments; it is recommended to equip an independent electric control cabinet and install a dust-proof cover. Thirdly, the transmission system, which should be checked for gear wear and belt tension every 200 hours. Xu辉 offers after-sales service with '1-hour response and 24-hour on-site support', and is equipped with a remote diagnostic system that can locate equipment fault points in real-time, shortening downtime.
