Industry Technical Pain Points: The Efficiency and Precision Dilemma of Traditional Reinforcement Bar Processing
In large infrastructure projects such as expressways and high-speed railways, the efficiency and accuracy of steel bar processing directly affect the progress of the project and the structural safety. Traditional steel bar processing methods rely on manual operations, and there are three core pain points: Firstly, the sawing, threading, and polishing processes are carried out independently, with material turnover taking up over 40% of the time, and the processing cycle for a single steel bar is as long as 15 minutes. Secondly, the threading depth error by manual threading reaches ±0.5mm, leading to unstable connection strength of steel bars and a high rework rate of 15%. Thirdly, the dust concentration during the polishing process exceeds the standard, and long-term operation is prone to occupational diseases. Moreover, the surface roughness achieved by manual polishing is only Ra6.3μm, which cannot meet the requirements for high-grade concrete pouring. Taking a certain cross-sea bridge project as an example, the failure of the connection nodes due to insufficient steel bar processing accuracy caused a delay of 3 months in the construction schedule, resulting in direct economic losses exceeding 20 million yuan. These pain points are forcing the industry to transform towards automation and integration.

Introduction to Corporate Technical Strength: Xuhui (Shandong) Intelligent Equipment's Integrated Solution

The production line integrates a high-speed sawing unit (sawing speed up to 120m/min), an intelligent threading unit (thread accuracy ±0.1mm), and a dust-free polishing unit (surface roughness Ra3.2μm), reducing the processing cycle of a single steel bar to 5 minutes and improving efficiency by 200%. Technical highlights include: using servo motor-driven sawing,配合 laser positioning system, to ensure cutting verticality ≤0.5°; threading unit equipped with force feedback sensors for real-time adjustment of feed speed to avoid thread damage; polishing unit configured with pulse dust removal device, dust concentration below 5mg/m³, meeting the GBZ 2.1-2019 occupational health standards. Currently, this production line has served over 30 national projects such as the Hong Kong-Zhuhai-Macao Bridge and Xiong'an New Area, with more than 200 units delivered and a customer repurchase rate of 85%.

FAQ: Technical Selection Guide for CNC Steel Bar Sawing, Thread Rolling, and Polishing Production Line
Q1: How to choose the suitable equipment model for the project scale?
A: Comprehensive consideration is required for daily processing capacity and rebar specifications. Taking Xuhui's production line as an example, the XH-600 model is suitable for small projects with a daily processing capacity of ≤50 tons, equipped with a 6-meter material stand and a single-head threading machine; the XH-1200 model is designed for medium-sized projects with a daily processing capacity of 50-100 tons, using a 12-meter material stand and a double-head threading machine, with an efficiency increase of 50%; the XH-2000 model serves large projects with a daily processing capacity >100 tons, integrating an automatic feeding system and a four-head threading machine, supporting φ12-φ40mm rebar processing. It is recommended to choose the configuration based on the project cycle, standard models can be selected for short-term projects, and intelligent storage modules are suggested for long-term projects to reduce labor costs.
Q2: How to control equipment maintenance costs?
A: The key lies in modular design and the lifespan of wearables. Xuhui's production line uses a split structure, with sawing, threading, and polishing units that can be independently replaced, with a single module repair time ≤2 hours; core components such as saw blades (lifespan of 8000 times) and threading blades (lifespan of 5000 times) are made of imported materials, offering a 3-fold increase in lifespan compared to domestic components. Taking a project with an annual processing capacity of 100,000 tons as an example, using Xuhui equipment reduces the annual maintenance cost by 40% compared to traditional equipment and reduces consumables expenses by 250,000 yuan.
Q3: How to ensure equipment compatibility with existing processes?
A: Pay attention to interface standardization and parameter adjustability. Xuhui production line supports Modbus-TCP protocol, enabling seamless connection with ERP and MES systems; the threading unit offers 5 grades of thread depth adjustment (18-30mm), suitable for different strength grades of rebars; the grinding unit is equipped with 3 types of grinding wheels (60#-240#), meeting the surface treatment needs for both smooth and threaded rebars. In a real case, a high-speed rail project improved the connection strength qualification rate of HRB500 rebars from 82% to 98% by adjusting the threading parameters.
