Product Details
The CNC steel bar shearing production line is a large-scale automatic steel bar processing equipment integrating automatic feeding, intelligent straightening, precision cutting, classified sorting and CNC control. It is tailor-made to solve the pain points of low efficiency, insufficient precision, high labor cost and weak batch processing capacity in traditional steel bar shearing operations. Integrating servo drive technology with the actual processing needs of construction projects, this equipment realizes the full-process automatic operation of straight bar from raw material feeding to finished product sorting. It can accurately process steel bars of different specifications and strength grades, and is widely used in high-consumption steel bar processing scenarios such as subway segment factories, housing construction projects, bridge tunnels, prefabricated component factories and large-scale steel bar processing and distribution centers. It is a core equipment for improving the efficiency of steel bar shearing operations, ensuring processing quality and reducing comprehensive costs.
I. Core Structure and Working Process
The equipment adopts a modular integrated design and consists of five core modules: automatic feeding system, intelligent straightening system, precision cutting system, intelligent sorting system and CNC control system. Each module is intelligently linked to realize batch and efficient processing of steel bars:

III. Core Competitive Advantages
1. Efficient Batch Processing, Doubled Production Capacity
Adopting a linkage design of servo drive and mechanical cutting, the SGS150 model can cut 6 pieces of Φ32 threaded steel at a time, which is 5-6 times more efficient than traditional single-piece shearing equipment. The full-process automatic operation only requires 1-2 operators to complete raw material replenishment and parameter monitoring, reducing labor costs by more than 70% compared with the manual + semi-mechanical mode. Calculated based on a 10-hour single shift, the SGS150 model can process more than 80,000 pieces of Φ20 threaded steel per day, meeting the batch processing needs of large-scale projects.
2. Wide Compatibility and Adaptability, Diverse Scenarios
Breaking through the single-specification processing limitation of traditional equipment, the SGS150 model can cut Φ50mm high-strength steel bars at maximum, covering the full-specification bar processing needs from Φ10 to Φ50. It supports mixed feeding of steel bars of multiple specifications, automatically matches processing parameters through the diameter identification module, and can switch between different specifications without replacing tools, adapting to the steel bar processing needs of various scenarios such as subway segments, bridge piles and high-rise buildings.
3. Precision and Stable Shearing, Controllable Quality
Adopting a combined design of scissor-type knife edge and alloy blade, the cutting process is stable without impact, with flat and burr-free cuts and deformation ≤0.5mm, which completely solves the problem of end warping in traditional shearing. The dual closed-loop control of servo motor + encoder ensures that the cutting length error is controlled within ±1mm, and the product qualification rate reaches 100%, avoiding rework loss caused by dimensional deviation and increasing material utilization rate by 4%-6%.
4. Intelligent Integration and Linkage, Flexible Production
High-end models are equipped with modular expansion interfaces, which can be linked with equipment such as steel bar bending centers, threading machines and palletizing robots to build a full-process intelligent production line from shearing to forming. The 10-inch touch screen supports CAD drawing import and parameter setting. The storage function of more than 100 sets of processing plans is suitable for multi-batch and small-batch production, and the parameter switching time is reduced by more than 90% compared with traditional equipment, realizing seamless order connection.
5. Durable and Low-Consumption Design, Worry-Free Operation and Maintenance
Core components are made of high-wear-resistant materials. The shearing blade is made of tungsten steel alloy, which can be processed continuously for more than 80,000 times after a single replacement; the main machine head is equipped with a distributed oil injection system that automatically lubricates key parts, and the annual equipment failure rate is less than 3%. The energy-saving servo system reduces energy consumption by 30% compared with traditional equipment. Calculated based on processing 5,000 tons of steel bars per year, it can save more than 200,000 yuan in electricity costs.
IV. Application Scenarios and Successful Cases
This equipment is suitable for various high-consumption steel bar processing scenarios, especially for standardized steel bar processing in subway segment factories, large-diameter steel bar blanking in bridge tunnels, batch steel bar processing in prefabricated component factories and multi-specification processing needs in large-scale steel bar processing and distribution centers. At present, it has been successfully applied in projects such as a subway group segment factory, a bridge project of China Construction Eighth Engineering Division and a large prefabricated component industrial park. Among them, after a subway segment factory adopted the SGS150 production line, the steel bar shearing efficiency increased from 15 pieces/minute of traditional technology to 120 pieces/minute, the single-shift production capacity increased by 7 times, the material loss rate decreased from 7% of traditional technology to 2.5%, and the annual raw material cost was saved by more than 1.8 million yuan. The product precision fully meets the requirements of Code for Acceptance of Construction Quality of Concrete Structure Engineering (GB50204-2015).
