2D Wire Bending Machine: High-Efficiency Intelligent Manufacturing Solution for Automated Hanger Production

一、Equipment Overview

Equipment Name: 2D Wire Bending Machine

Industry Positioning: Specifically designed for iron wire hanger products such as clothes hangers, pants hangers, and scarf hangers. Integrating 4-axis servo drive and automated wire bending technology, it achieves full-process precision forming of 2-6mm iron wires from feeding to finished hangers. Aiming at the strict requirements of hangers for load-bearing strength and hook curvature consistency, the equipment solves the pain points of large curvature deviation and low efficiency in traditional manual wire bending with ±0.5mm-level precision and a production speed of 10-15 pieces/minute, becoming the core equipment for large-scale hanger production.

Technical Core: Equipped with a 32-bit PLC control system and Yaqi servo system, supporting the storage of 4,000 sets of production data. It realizes flexible production of hanger main bodies, hooks, anti-slip strips and other components through 300 action combinations, adapting to various cross-sectional shapes such as round, flat, and square wires.

  • Straightening mechanism: Multiple groups of adjustable straightening wheels ensure the straightness error of iron wires <0.3mm, laying the foundation for the curvature precision of hanger hooks.
• Bending and Cutting Mechanism:
  • Bending mold: Adjustable positioning columns combined with 360° rotating mold heads, supporting up-down movement and clockwise/counterclockwise rotation of inner/outer molds, realizing the forming of complex shapes such as U-shaped main bodies and S-shaped hooks of hangers.
  • Cutter system: 1.0kW servo-driven cutter, suitable for cutting 2-6mm iron wires, with a cut verticality ≤1° and no burrs, meeting the surface finish requirements of hangers.
• Pneumatic Auxiliary System:
  • Number of cylinders: 1, number of solenoid valves: 1, driven by 0.6MPa pressure for actions such as feeding, retreating, and positioning, with a response time <50ms and process synchronization accuracy of ±0.2mm.

（三）Precision and Efficiency Indicators

• Production Efficiency: 10-15 pieces/minute (standard hangers), 20-25 pieces/minute for 200*200mm square frames, 5-8 times higher efficiency than traditional manual operations.
• Forming Precision:
  • Bending accuracy ±0.5mm to ensure the consistency of hanger hook curvature.
  • Wire feeding accuracy ±0.5mm to guarantee the splicing precision of hanger main bodies and hooks.
  • Angle control ±180° to meet the bending angle requirements of components such as hanger anti-slip strips and pants hanger clips.

三、Core Advantages of the Equipment

1. Flexible Production Capability:
   • Supports the forming of hanger components with wire diameters of 2-6mm and arbitrary curvatures. Through 4,000 sets of data storage and 300 action combinations, it can quickly switch between products such as clothes hangers, pants hangers, and scarf hangers, with a model change time <3 minutes.
   • Compatible with materials such as Q235 carbon steel and galvanized iron, and can pass the 48-hour salt spray test after surface treatment, meeting the anti-rust requirements of hangers.
2. Intelligent Control and Operational Convenience:
   • Chinese/English dual-language system, touch screen + button dual-operation mode, supporting production data upload/download. Newcomers can start working after 1 hour of training.
   • Real-time monitoring of parameters such as bending angle and wire feeding length, automatic alarm and shutdown for abnormalities, with a rejection rate ≤0.5%.
3. Energy Saving and Durability:
   • Total power 6.2kW, 35% more energy-saving than traditional equipment. Combined with a heat dissipation system, the temperature of core components ≤65℃, and the continuous operation life of the equipment exceeds 80,000 hours.
   • The mold is made of Cr12 alloy material (hardness 58-62HRC), with a service life of over 100,000 times, reducing the annual maintenance cost by 10,000 yuan.

四、Application Scenarios: Coverage of All Hanger Categories

• Standard Hanger Production:
  • Forming of hanger main bodies with a length of 400-600mm. Through ±0.5mm precision control, the hook opening size is ensured to be uniform, adapting to different wardrobe hanging rods.
  • 180° bending combined with a 360° rotating mold head to realize the hook tail barb process, with a load-bearing capacity of over 5kg to prevent clothes from slipping.
• Functional Hanger Processing:
  • Pants hanger hooks: Small ring forming with a diameter of 25-100mm. Through ±0.5mm precision control, the clip swing amplitude is <1°.
  • Anti-slip strips: Flat wire bending forming, with a flatness <0.5mm, ensuring the stability of clothes when hung.
• Derivative Applications:
  • Scarf hangers: Wave-shaped lace hangers, realizing customized production through rapid mold change.
  • Industrial parts racks: 6mm wire diameter large load-bearing frames, meeting the hanging needs of workshop tools, with a single-point load-bearing capacity ≥10kg.
