2D Wire Bending Machine: Automated Production Solution for Aquaculture Cages

Core Parameters and Industry Positioning

A 4-axis high-precision forming equipment specially designed for intelligent production of aquaculture cages, adopting Inovance servo power system and Yaqi servo control system, enabling high-speed bending of 2-6mm iron wires (round/flat/square wires). With a standard capacity of 10-15 pieces/min (200×200mm square frame), the equipment constructs a full-process automated production line to meet diverse aquaculture scenarios such as fishpond fences, shrimp pond partition cages, and seedling temporary breeding cages, improving efficiency by 500% compared to traditional manual production.

Technical Innovations and Performance Advantages

1. High-Speed Feeding and Precision Positioning System

2. 4-Axis Linkage Progressive Bending Technology

3. Intelligent Production Management System

• Rapid model switching: 4,000 groups of data storage support quick switching between 2mm seedling cages and 6mm adult fish cages within 10 minutes.
• Process self-optimization: The system automatically matches the optimal bending speed according to wire diameter (200rpm for 2mm, 120rpm for 6mm).
• Remote operation and maintenance: GPRS module uploads production data in real time and automatically pushes alarms to managers' phones in case of failures.
  

Analysis of Aquaculture Cage Production Process

1. Wire Preprocessing Flow

• Straightening treatment: 9-roller straightening system uses 0.5MPa light pressure for 2mm thin wires and 1.2MPa heavy pressure for 6mm thick wires, controlling straightness within 0.08mm/m.
• Fixed-length cutting: 15° bevel cutting blade with 1.0kW cutting servo controls cutting force of 6mm iron wire at 8kN±0.5kN, with end surface roughness Ra≤12.5μm.

2. Typical Forming Process (4mm Iron Wire 300×300mm Frame)

1. Feeding servo conveys 450mm wire → secondary straightening by 9-roller mechanism.
2. Outer mold rotates to 0°, inner mold moves up to complete bottom positioning.
3. Bending servo drives outer mold to rotate 90° clockwise for right-angle bending.
4. Feeding servo conveys another 300mm, outer mold rotates 180° counterclockwise for diagonal bending.
5. Cutting servo acts to cut the wire, and the finished product falls automatically.
   Single cycle: 2.8 seconds, 6x higher efficiency than manual operation.

3. Quality Control System

• On-line detection: 12μm laser micrometer scans in real time, automatically rejecting products with angle deviation >0.5° or side length tolerance >0.8mm.
• Durability test: 100,000 fatigue tests on 6mm iron wire bending points, with fracture times ≥85,000 (industry standard ≥50,000).
