Product Introduction
The steel arch frame production line of Xuhui (Shandong) Intelligent Equipment Co., Ltd. adopts a fully automated process, integrating core technologies such as cold bending forming, intelligent cutting, robotic welding, and digital quality control. The production line takes the CNC cold bending machine as its core and achieves precise bending of I-beams through a PLC control system. In the welding process, multiple collaborative robots are used, equipped with a three-dimensional vision positioning system that can automatically identify weld seams and complete end-plate welding. The efficiency of single-weld formation is increased by more than 40% compared with traditional processes.
This production line offers modular, flexible production capacity. With adjustable conveying brackets and C-type positioners, the product qualification rate remains stable at over 99.8%. Key processes such as continuous welding, cutting, and plate mounting are all carried out without manual intervention, requiring only 1–2 operators per shift—an 80% reduction in labor compared with traditional manual operation. The line also integrates an AI visual inspection system, which monitors welding quality and dimensional accuracy in real time, automatically sorts semi-finished products that require re-welding, and ensures consistent quality of finished products.
Notably, the production line adopts laser CNC cutting technology instead of traditional hydraulic cutting, increasing material utilization by 30%. At the same time, through the Internet of Things platform, it enables remote monitoring of equipment status and real-time analysis of production data, providing a basis for subsequent process optimization. This intelligent and intensive production model not only significantly improves the processing efficiency and quality stability of tunnel steel arch frames, but also supports green manufacturing by reducing dust pollution and energy consumption.

Specialized training and passing the assessment are required. Unlicensed personnel are strictly prohibited from operating. New employees must be mentored by experienced staff for at least three working days before working independently.
It is strictly prohibited to modify the preset parameters of the equipment without authorization. If adjustment is necessary, it must be calculated by technicians, modified through a permission password, and recorded in the parameter change ledger.
- Feeding and material compatibility
Before loading, the specifications of the raw materials must be checked. Mixing different types of steel is strictly prohibited to avoid material jamming or processing deviations. The material length must match the stroke of the conveying bracket. Materials that are too long or too short are prohibited from being fed.
II. Safety Protection: Strictly adhere to protection measures for high-risk processes to prevent personal and equipment accidents
- Personal protective equipment is mandatory
- Laser cutting station: Anti-laser goggles must be worn, and direct viewing of the laser beam is strictly prohibited.
- Welding station: Flame-retardant work clothes, welding masks, and insulating gloves must be worn to prevent arc burns or electric shock.
- Full production line operation: All personnel must wear safety helmets and anti-slip work shoes. Loose clothing or jewelry is strictly prohibited to prevent entanglement in the conveying mechanism.
- Do not tamper with the safety devices of the equipment
The light curtain and mechanical interlock devices of the production line must be kept in good condition. When triggered, the equipment must stop immediately. Shielding or removing them is strictly prohibited.
Emergency buttons (red, distributed in prominent locations at each workstation) must be tested regularly (once a week) to ensure that the entire line powers off when pressed. Blocking them is strictly prohibited.
- Workshop environmental safety
Safety passages must remain unobstructed, and materials or tools must not be stacked in them.
The welding fume purification system and laser cutting dust removal equipment must be started simultaneously to ensure workshop dust concentration complies with GBZ 2.1 standards. Filter cartridges must be cleaned regularly (once a month).
III. Quality Control: Real-time monitoring of key indicators to prevent non-conforming products from circulating
- Inspection of processing parameters
Spot-check processing accuracy every two hours: the weld seam height should be ≥ the design value. If it exceeds the standard, the machine must be stopped for adjustment.
The AI visual inspection system must be calibrated daily before startup (using standard samples) to ensure it can detect defects such as weld porosity and undercut. Non-conforming products must be marked and isolated, and are prohibited from entering the next process.
- Raw materials and finished products management
Raw materials must be accompanied by material certificates. Before entering the site, their mechanical properties must be randomly inspected. Rusted, deformed, or unqualified steel is strictly prohibited.
Finished products must be stored separately, stacked no more than three layers high (to prevent deformation), and coated with anti-rust paint (enhanced protection is required if environmental humidity exceeds 60%).
IV. Emergency Response: Standardize handling of sudden situations to minimize losses
- Equipment failure handling
- Material jamming fault: Immediately stop the machine, cut off the power supply, check the jamming position, and clear it with a special tool. Do not forcibly restart the equipment.
- Abnormal noise or smoke: Immediately cut off the power, investigate the cause (such as motor overload or short circuit), contact the equipment manufacturer’s after-sales service, and do not disas
Equipment Maintenance and Upkeep
Regular maintenance can extend service life and reduce malfunctions
Daily maintenance (before and after operations)
- Before startup: Check whether the equipment’s power supply and air source are normal, and whether there are any abnormal noises from the guide rails of the cold bending machine or the joints of the robot.
- After shutdown: Clean residue from the laser cutting head (using a dedicated brush) and from the nozzle of the welding robot’s torch (to prevent welding wire from sticking). Add lubricating oil to the bearings of the conveying bracket.
Regular maintenance (performed periodically)
- Weekly: Check the cooling fan of the PLC control cabinet (ensure it is not blocked) and the insulation layer of the wires and cables (ensure there is no damage).
- Monthly: Calibrate the accuracy of the servo motor of the cold bending machine and replace the wire feeding wheel of the welding robot.
- Quarterly: Disassemble and inspect the laser cutting focusing lens (for scratches) and test the grounding resistance of the equipment (to prevent leakage).
- A maintenance ledger must be established to record the maintenance time, content, and replaced parts for traceability.
