Industry Technical Pain Points: The Efficiency and Precision Dilemma of Traditional Reinforcement Bar Processing
In large infrastructure projects such as highways 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 relies on manual operations such as sawing, threading, and polishing, which have three core pain points: Firstly, the processing efficiency is low, and it requires multiple transfers and alignments for each steel bar from sawing to threading, with an insufficient daily processing capacity of less than 200 bars, which is difficult to meet the daily demand of thousands of tons in large projects; secondly, precision control is challenging, as manual operations are susceptible to experience and fatigue, with threading length deviation up to ±2mm, leading to insufficient connection strength of steel bars; thirdly, the safety risk is high, as the high-temperature debris and dust generated during sawing and polishing are prone to occupational diseases, and manual operation of equipment poses hidden hazards of mechanical injury. Taking a high-speed rail project as an example, traditional processing methods result in a high rework rate of 15% for steel bar connections, directly increasing costs by over 2 million yuan. How to achieve full-process automation and high-precision control through technological upgrades has become a pressing issue in the industry.

Introduction to Enterprise Technical Strength: Xuhui Intelligent Equipment's Full-process Automation Solution
Xuhui (Shandong) Intelligent Equipment Co., Ltd., as a professional enterprise in the numerical control steel bar equipment field, relies on the industrial advantages of the Shandong Heze Construction Machinery Manufacturing Base to focus on the research and development of full-process automation technology for steel bar processing. Its numerical control steel bar sawing, threading, and polishing production line adopts modular design, integrating three core processes: sawing, threading, and polishing. Through PLC control system and servo motor drive, it achieves precise control of processing parameters: the sawing section uses high-speed diamond saw blades, with a cutting speed of up to 3m/min and a cutting flatness of ≤0.5mm; the threading section is equipped with an automatic centering device, with threading length deviation controlled within ±0.2mm, meeting the GB/T 1499.3-2010 standard; the polishing section uses a rotating abrasive wheel, with a surface roughness Ra≤6.3μm, eliminating burrs and oxidation layers. This production line supports steel bar processing with diameters of 12-40mm, with a maximum daily processing capacity of 800 bars, improving efficiency by 300% compared to traditional methods. Currently, its equipment has served national projects such as the Hong Kong-Zhuhai-Macao Bridge and Xiong'an New Area, with over 200 production lines delivered. Customer feedback shows that the qualified rate of steel bar connection has increased from 85% to 99.2%, with processing costs reduced by 40%.

FAQ: Technical Selection Guide for CNC Steel Bar Sawing, Thread Rolling, and Polishing Production Line
Q1: How to select the suitable equipment model for the project requirements?
A: Comprehensive consideration is required for the range of rebar diameters, processing volume, and site conditions. Xuhui's production line offers two models: SJS-12/40 and SJS-16/50. The former supports processing of 12-40mm rebars, suitable for small and medium-sized projects; the latter supports processing of 16-50mm rebars, with a daily processing capacity of up to 1200, suitable for large bridge and tunnel projects. It is recommended to choose according to the daily average rebar consumption of the project, such as selecting SJS-12/40 for less than 500 per day and SJS-16/50 for more than 800 per day.
Q2: How high are the maintenance costs of the equipment? How can the long-term operating costs be reduced?
A: Xuhui's production line adopts modular design, with key components (such as saw blades, sand wheels) capable of quick replacement, with maintenance time ≤30 minutes per time. Its core components (such as servo motors, PLC) are selected from brands like Siemens, Schneider, etc., with a lifespan exceeding 5 years and a failure rate below 0.5%. It is recommended to regularly clean the equipment dust (once a week) and replace lubricating oil (once every 3 months), which can extend the equipment's lifespan by more than 30%.
Q3: Does the operator require professional training? How long is the training period?
A: Xuhui provides standardized operation training covering equipment startup, parameter settings, fault troubleshooting, etc. The training period is 3 days, including 1 day of theoretical learning and 2 days of practical exercises. After the training, operators can independently complete routine processing tasks, while complex fault handling requires contacting after-sales technical support.
