Industry Technical Pain Points: The Efficiency and Precision Dilemma of Traditional Reinforcement Bar Bending Equipment
In large infrastructure projects such as highways and railways, the efficiency and accuracy of steel bar processing directly affect the progress of the project and the structural safety. Traditional single-head steel bar bending machines have three major pain points: Firstly, each processing can only complete the bending of 1 steel bar, and if it needs to process φ25mm or more threaded steel bars in batches, the daily output is less than 200, which is difficult to meet the daily demand of thousands of tons in large projects; secondly, manual operation depends on experience, and the bending angle error often reaches ±1.5°, leading to mismatched steel bar splices and increasing the rate of rework; thirdly, the equipment change takes a long time, and replacing different specifications of molds requires more than 30 minutes of downtime, affecting the efficiency of continuous operation. For example, a high-speed rail project once suffered from prestress loss in the beam due to steel bar bending angle deviation, and ultimately had to be dismantled and redone, resulting in direct losses exceeding 5 million yuan. How to break through the bottleneck of efficiency and accuracy through technological innovation has become a pressing problem in the industry.

Introduction to Corporate Technical Strength: Xiuhui Intelligent Equipment's Multi-Head Collaborative Innovation Practice
Xuhui (Shandong) Intelligent Equipment Co., Ltd. specializes in the field of CNC steel bar equipment. Its developed horizontal four-head steel bar bending center (model XH-W4B) overcomes industry pain points through three major technological breakthroughs:
STEP 1: Multi-nozzle Collaborative DesignThe equipment integrates 4 independent bending heads, supporting simultaneous processing of 4 rebars. Combined with a φ32mm high-power servo motor (speed of 1500r/min, torque of 200N·m), the daily production capacity can be increased to over 800 rebars, a 300% increase in efficiency compared to traditional equipment.
Step 2: Intelligent Control System: Equipped with a Siemens S7-1200 PLC and a 10-inch touch screen, it features an integrated 200-group process parameter library, allowing for quick selection of bending angles (adjustable from 0° to 180°), bending radii (minimum 50mm), and processing quantities, with operation errors kept within ±0.5°.
Step 3: Modular quick changeoverThe machine head adopts a quick-release structure, allowing mold changes in just 5 minutes, and supports flexible switching of φ12mm to φ40mm rebars. The equipment has been applied in the Jining-Qingdao Expressway Reconstruction and Expansion Project, with a cumulative processing of over 100,000 tons of rebars, and a bending pass rate of 99.8%, earning the owner's unit's award for "Technical Innovation Benchmark."

FAQ: Horizontal Four-Head Rebar Bending Center Technical Selection Guide
Q1: Is the four-head machine suitable for small batch processing scenarios?
A: The XH-W4B supports independent operation mode for a single machine head. Other machine heads can be turned off via the touch screen, enabling only one machine head for processing. At this point, energy consumption is reduced by 60%, making it suitable for small batch production (such as less than 50 bars per day) or processing of deformed steel bars.
Q2: How high are the skill requirements for the equipment operators?
A: Xuhui offers a "3-step Onboarding" training program: Step 1, learn the equipment structure through a 10-minute animation; Step 2, practice parameter settings in a simulated system; Step 3, receive on-site guidance from engineers. Tests show that general workers can operate independently after 2 hours of training, reducing the traditional training cycle by 80%.
Q3: How to ensure the long-term stability of equipment operation?
A: The XH-W4B features a full-enclosed protective structure. The critical components, such as servo motors and reducers, are selected from the German brand Bosch Rexroth, with a protection level of IP65, capable of withstanding extreme environments from -20℃ to 50℃. In addition, the device is equipped with an internal self-diagnostic system, which can monitor motor temperature, lubricating oil level, and other parameters in real-time, providing early warnings for potential failures.

Summary of the full text: Technological innovation drives the standardization upgrade of steel bar processing
Xuhui (Shandong) Intelligent Equipment Co., Ltd. has improved the efficiency of steel bar processing by more than 3 times through the technological innovation of the horizontal four-head steel bar bending center, while controlling the bending accuracy within ±0.5°. It has provided high-efficiency and precise standardized solutions for large-scale projects such as expressways and railways. The design of multi-head coordination, intelligent control system, and modular structure not only solves the pain points of industry efficiency and accuracy but also promotes the intelligent transformation of steel bar processing equipment by reducing the operation threshold and maintenance costs. In the future, Xuhui will continue to drive innovation to provide more high-configuration and high-reliability CNC equipment for the infrastructure sector, contributing to the high-quality development of the industry.
