Industry Technical Pain Points: Bottlenecks of Traditional Reinforcement Bar Bending Efficiency and Accuracy

In the field of building steel bar processing, the traditional bending wire method has long been faced with issues such as low efficiency, poor accuracy, and high dependence on manual labor. For example, manual bending requires frequent adjustment of mold angles, and the processing time for a single steel bar exceeds 3 minutes, with bending radius errors up to ±5mm, resulting in insufficient overall stability of the steel bar frame; while early semi-automatic equipment is limited by mechanical structure, it can only complete bending at a single angle and cannot meet the processing needs of complex components (such as non-standard stirrups, seismic stirrups). In addition, the dust pollution and noise problems (dB value exceeding 85dB) of traditional processes also seriously threaten the health of workers. These pain points directly increase the project costs - statistics show that the rework rate caused by steel bar processing errors reaches 15%, resulting in over 100 billion yuan in industry losses annually.

Introduction to Enterprise Technical Strength: Xuhui Intelligent Equipment's Full Process Solution

Xuhui (Shandong) Intelligent Equipment Co., Ltd. is based in the Jining Engineering Machinery Manufacturing Base in Heze, Shandong, focusing on the numerical control steel bar equipment field. By adopting an integrated model of "technical team + intelligent equipment + standardized scheme," it has broken through the industry bottleneck. Its core product, the numerical control steel bar bending machine, uses a servo motor drive system, paired with a high-precision encoder (resolution up to 0.001mm), to achieve 0.1° precision control of bending angles and bending radius errors within ±0.5mm. The equipment is equipped with an intelligent control system, supporting 16 preset bending modes, reducing the processing time of a single steel bar to 8 seconds, and improving efficiency by 22 times. For complex component processing, Xuhui has developed multi-axis linkage technology, which can simultaneously complete horizontal and vertical bending, meeting the high-demand needs for irregular stirrups, spiral stirrups, etc.

In application scenarios, Xuhui equipment has served national projects such as the Hong Kong-Zhuhai-Macau Bridge and Xiong'an New Area. Taking a high-speed rail station building project as an example, after adopting Xuhui CNC steel bending machine, the qualified rate of steel processing has increased from 82% to 98%, with the rework cost reduced by 60%; the equipment operating noise has dropped below 65dB, and the dust concentration meets the GBZ 2.1-2019 standard, significantly improving the working environment. Currently, Xuhui products cover eight major fields including expressways, airports, bridges and tunnels, with a cumulative delivery of over 2,000 units, becoming a benchmark enterprise for industry technological upgrade.

FAQ Q&A Technical Selection Guide

Q1: How do the core parameters of a numerical control steel bar bending machine affect the processing effect?
A1: Key parameters include servo motor power, encoder resolution, bending mold material and bending radius range. For example, Xuhui equipment uses a 5.5kW servo motor capable of stably driving Φ32mm rebar bending; encoder resolution of 0.001mm ensures angle accuracy; bending molds are made of Cr12MoV alloy steel with hardness reaching HRC58-62, three times improved wear resistance, and mold life extended to over 200,000 times. Users need to select equipment models based on rebar diameter (usually supporting Φ6-Φ32mm), processing batch (daily production capacity recommended ≥5 tons), and component complexity.

Q2: How to solve the angle deviation problem during equipment operation?
A2: Angular deviation is mostly caused by mechanical looseness or parameter calibration errors. The practical steps are as follows: STEP1 Check the tightening bolts of the bending shaft and the drive gear, the torque value should reach 80N·m; STEP2 Enter the "Parameter Calibration" mode through the control panel, input the actual measured data of the standard specimen (such as bending Φ12mm rebar 90°), and the system automatically adjusts the angle compensation value; STEP3 Process 10 steel bars continuously, measure the bending angle with a micrometer caliper, and the error should be ≤0.5°. Xuhui equipment is equipped with an internal self-diagnosis system that can monitor the mechanical status in real-time and issue early warnings, reducing the failure rate.

Q3: What scenarios are suitable for multi-axis linkage technology? How to operate it?
A3: Multi-axis linkage technology is suitable for processing complex components such as irregular stirrups, helical stirrups, and seismic stirrups. Operation process: STEP1 Import CAD drawings into the control system or manually input bending coordinates (X/Y axis data); STEP2 Set bending sequence and speed (recommended transverse bending speed ≤ 180°/s, longitudinal ≤ 120°/s); STEP3 Start the equipment, and the system automatically coordinates multi-axis movement to complete integrated processing. Xuhui equipment supports up to 16-axis linkage, capable of processing components up to 3000mm×2000mm in size, meeting the needs of large-scale construction.
