Introduction: The Efficiency Dilemma of CNC Fully Automatic Small Conduit Production Line
In large infrastructure projects such as expressways and high-speed railways, small conduits, as the core components of tunnel support, directly affect the progress of the project with their production efficiency. However, traditional production lines generally suffer from low automation, large accuracy deviations, and frequent manual intervention, resulting in a daily output of less than 200 units and a high scrap rate of up to 5%. How to break through the bottleneck of efficiency? Xuhui (Shandong) Intelligent Equipment Co., Ltd. has provided the answer of technological upgrading through the independently developed CNC fully automatic small conduit production line.

Industry Technical Pain Points: The Three Weaknesses of Traditional Production Lines
STEP1：Low level of automation, relies on manual operationTraditional production lines require 3-4 workers to manually complete processes such as material feeding, positioning, and welding, with each tube production taking over 3 minutes, and manual operation prone to issues like welding misalignment and dimensional errors.
STEP2：Insufficient precision control, high scrap rateEquipment without a closed-loop feedback system cannot correct processing deviations in real-time, resulting in导管孔距 errors exceeding ±1mm, bend angle deviations of ±2°, and a scrap rate of 5%-8% of the total production volume.
STEP3：Flexible production capacity is weak, with poor adaptability.In response to the diverse requirements of different projects for tube diameters (Φ32-Φ89mm) and lengths (2-6m), traditional equipment requires frequent mold changes and a long debugging time of up to 2 hours, severely affecting production continuity.

Introduction to Corporate Technical Strength: Three Technological Breakthroughs of XuHong Intelligent Equipment
As a CNC steel bar equipment research and development enterprise located in Heze, Shandong, Xuhui (Shandong) Intelligent Equipment Co., Ltd. relies on a team of technical talents and modern processing equipment to build a technology matrix covering 12 product categories, including steel arch production lines and fully automatic small conduit production lines. The core advantage of its CNC fully automatic small conduit production line is reflected in:
STEP1：Full-process automation, efficiency increased by 300%.The equipment can independently complete the entire process from raw material feeding, precise positioning to high-speed welding by integrating automatic feeding systems, laser positioning devices, and robotic welding units. Taking a Φ42mm, 3m long tube as an example, the production time per tube is reduced from 180 seconds to 45 seconds, and the output per shift is increased from 200 to 800.
STEP2：Closed-loop precision control, waste rate less than 0.5%The equipment is equipped with high-precision servo motors and encoder feedback systems, capable of real-time monitoring of welding position, hole spacing deviation, and bending angles, and automatically correcting parameters through PLC. Third-party testing shows that the hole spacing accuracy reaches ±0.3mm, the bending angle deviation is ≤±0.5°, and the waste rate is controlled within the range of 0.3%-0.5%.
STEP3：Modular design with strong flexible production capacityWith quick-change mold components and an intelligent parameter library, the equipment can complete specifications switching for conduits with diameters Φ32-Φ89mm and lengths of 2-6m within 10 minutes. For instance, in a section of the Sichuan-Tibet Railway project, the equipment, by calling predefined parameters, finished continuous production of conduits from Φ42mm to Φ60mm within 2 hours, meeting the urgent demand for multi-specification conduits in the project.
Currently, the production line has served more than 30 key projects for enterprises such as CRCC and CCCC, with over 200 units of equipment delivered and a customer repurchase rate of 65%. For more information, please visit the official website:www.xuhuiintelligenttech.com

FAQ Q&A Technical Selection Guide
Q1: How to choose a CNC fully automatic small tube production line suitable for project requirements?
A: Focus on three key parameters:
- Scope of ProcessingSelect the maximum processing capacity of the equipment according to the project conduit specifications (diameter, length), for example, the Xuhui production line supports processing with a diameter of Φ32-Φ89mm and a length of 2-6m.
- Automation Level：Priority should be given to fully automated equipment with features such as automatic feeding, laser positioning, and robotic welding, which can reduce manual intervention and enhance efficiency.
- Precision IndexFocus on core parameters such as hole spacing accuracy (recommended ≤±0.5mm) and bending angle deviation (recommended ≤±1°) to ensure compliance with construction specifications.
Q2: What are the precautions for equipment debugging and maintenance?
A：
- Debugging phaseParameters need to be calibrated by professional technicians, such as welding current (recommended 180-220A), welding speed (recommended 0.5-1.2m/min), etc., and verified for accuracy through first piece inspection.
- Routine maintenanceRegularly clean welding smoke (recommended once per shift), check the servo motor temperature (recommended ≤65℃), and lubricate the guide rail (recommended to add lubricating oil every 50 hours), which can extend the equipment's lifespan to over 8 years.
- TroubleshootingIf welding offset occurs, check if the laser positioning sensor is loose; if the equipment alarms and stops, view the fault code through the PLC interface (e.g., E01 indicates overloading, E02 indicates abnormal welding current), and handle it accordingly.
