Industry Technical Pain Points: Breakthrough Needed for Traditional Reinforcement Bar Bending Efficiency and Precision

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 single-head steel bar bending equipment has three major pain points: Firstly, it can only process a single steel bar at a time, and when faced with various specifications and batch sizes, it requires frequent mold changes and parameter adjustments. The maximum daily output is only 300 bars, which is difficult to meet the daily demand of a large-scale project that requires thousands of tons; secondly, manual operation relies on experience, and the bending angle error often exceeds ±1°, leading to loose steel bar joints and increasing the cost of later welding and alignment; thirdly, the equipment has low integration, requiring multiple auxiliary equipment for processes such as cutting and threading, occupying more than 50㎡ of space, with an utilization rate of less than 60%. These pain points force the industry to urgently need intelligent and integrated steel bar bending solutions.

Introduction to Corporate Technical Strength: Xiuhui (Shandong) Intelligent Equipment's Integrated Innovation Practice

Currently, this equipment has been applied in projects such as the Zhuhai Link of the Hong Kong-Zhuhai-Macau Bridge and the high-speed railway station in Xiong'an New Area. Customer feedback shows that the comprehensive cost of rebar processing has been reduced by 35%, and the construction period has been shortened by 20%.

FAQ Q&A Technical Selection Guide

Q1: What are the core technical parameters of the intelligent four-head rebar bending center?
A1: The core parameters of the Xuhui XH-QJW4-2023 equipment include: maximum bending rebar diameter Φ40mm (HRB500 grade), adjustable bending speed of 0.5-2r/min per machine head, total power of 45kW, applicable voltage of 380V±10%, equipment weight of 8.2 tons, and operational temperature range of -10℃ to +45℃. Its four independent control modules can store 20 sets of processing parameters, meeting the requirements of GB/T 1499.2-2018 "Steel for Reinforced Concrete - Part 2: Hot-rolled Ribbed Bars".

Q2: How to select the suitable rebar bending equipment for the project requirements?
A2: Selection requires considering three aspects:Capacity matchingAccording to the average daily steel consumption of the project (e.g., about 50 tons of steel per kilometer for expressways), select the number of equipment. Each XH-QJW4-2023 unit has a daily production capacity of 1,200 bars (based on Φ25mm steel bars), which can meet the needs of small and medium-sized projects.Specification compatibilityConfirm the maximum/minimum steel bar diameter and bending radius supported by the equipment. Xuhui equipment has a bending radius range of 50-500mm, covering over 90% of engineering needs.Integration requirementsIf the project site is limited or requires a reduction in manpower, prioritize equipment with integrated saw cutting and threading functions.旭辉equipment can reduce 2 operators, cutting labor costs by 40%.

Q3: How to control the equipment failure rate? What is the maintenance cycle?
A3: Xuhui equipment adopts modular design, with key components (such as servo motors, reducers) selected from brands like Siemens, SEW, etc., with a failure rate ≤0.5%. Daily maintenance requires checking the lubrication system oil level and cleaning the residue of bent molds per shift; replace gear oil every 500 hours, and check the encoder connection of the servo motor every 2000 hours; the equipment is equipped with an automatic diagnostic system, which can monitor motor temperature, hydraulic pressure, and other parameters in real-time, achieving a 95% accuracy rate in fault warnings, reducing downtime.

The summary of the full text refers to: Intelligent integration is the upgrading direction of steel bar processing equipment.
