Industry Technical Pain Points: Dual Challenges of Construction Reinforcement Processing Efficiency and Precision
In large infrastructure projects such as expressways and high-speed railways, the efficiency and accuracy of steel bar processing directly affect the progress and quality of the project. Traditional single-head steel bar bending equipment has three major pain points: Firstly, it can only process one steel bar at a time, with a daily maximum output of less than 800 bars (taking Φ25mm steel bars as an example), which is difficult to meet the daily demand of thousands of bars in large projects; secondly, it heavily relies on manual operation, with bending angle errors often reaching ±2°, leading to mismatched steel bar joints and a high rework rate of up to 15%; thirdly, the equipment occupies a large area, with a single-head machine requiring more than 10㎡ of space, and when multiple machines are placed in parallel, the site utilization rate is less than 60%. A high-speed railway project once suffered a delay of 12 days in pier casting due to the lag in steel bar processing efficiency, resulting in direct economic losses exceeding 2 million yuan. How to achieve "efficient, accurate, and compact" steel bar processing through technological innovation has become a pressing problem in the industry.

Introduction to Enterprise Technical Strength: Xuhui Intelligent Equipment's Horizontal Four-Head Solution
Xuhui (Shandong) Intelligent Equipment Co., Ltd. is located in the Heze Engineering Machinery Manufacturing Base of Shandong. Focused on the research and development of CNC rebar equipment for 12 years, it boasts a 30-person technical team and a 2000㎡ modern factory. Its horizontal four-head rebar bending center (model XH-W4) resolves industry pain points through three technological innovations:
Technical Principle and Parameters:Equipped with a four-head synchronous drive design, capable of processing 4 rebars (Φ12-Φ40mm) simultaneously. Fitted with a FANUC servo motor from Japan, the bending speed reaches 45°/second, with a daily production capacity of up to 3200 rebars (Φ25mm) increased by 300% compared to traditional equipment.
Precision control:Integrated with HEIDENHAIN encoder from Germany, bending angle error is controlled within ±0.5°. Combined with our independently developed "Intelligent Calibration System", it can automatically compensate for the elastic deformation of steel bars, ensuring joint errors less than 1mm.
Space Optimization:The equipment has a length of only 4.5m, a width of 1.8m, and occupies an area of 8.1㎡. It saves 62% of space compared to four single-head machines and supports modular assembly, allowing flexible expansion to an 8-head or 12-head system.

In an airport expansion project, the XH-W4 equipment operated continuously for 200 days without any failure, processed 260,000 steel rebars, and achieved a qualified rate of 99.2% in splicing, helping the project complete the main structure construction 18 days ahead of schedule, and was commended as a "Pioneer Unit of Technological Innovation" by the owner.

FAQ: Horizontal Four-Head Rebar Bending Center Technical Selection Guide
Q1: Is the four-head equipment suitable for small batch processing scenarios?
A: The XH-W4 supports the "single-head independent control" mode, allowing any machine head to be turned off. The minimum processing batch is 1 steel bar, with a single-bar processing energy consumption of only 0.8 kW·h, a 40% reduction compared to traditional equipment, suitable for mixed scenarios of small and large-scale processing.
Q2: What are the requirements for the rebar material of the equipment?
A: Compatible with common construction rebars such as HRB400, HRB500, with bending radius ≥ 4 times the diameter of the rebar (e.g., for Φ25mm rebars, the minimum bending radius is 100mm), the tensile strength loss of the rebars after bending is ≤5%, in compliance with GB/T 1499.2-2018 standard.
Q3: How to ensure long-term stability of operation?
A: Core components use imported brands: German Rexroth hydraulic system, Swedish SKF bearings. The entire machine passes a 2000-hour continuous fatigue test, with critical components having a lifespan exceeding 5 years; and offers "3-year full warranty + lifetime maintenance" service, responding to faults within 48 hours.
