2D Wire Bending Machine: High-Efficiency Intelligent Manufacturing Solution for Metal Curtain Hooks

Ⅰ. Equipment Overview

Equipment Name: 2D Wire Bending Machine

Industry Positioning: Specifically designed for metal curtain hooks, curtain accessories, and other iron wire products, integrating 3-axis servo drive and automated wire bending technology to achieve full-process precision forming of 2-6mm iron wires from feeding to finished hooks. Aiming at the strict requirements of curtain hooks for arc consistency and hook opening precision, the equipment solves pain points such as large arc deviation and low efficiency in traditional manual wire bending with ±0.5mm-level precision and a production speed of 8-10 pieces/min, becoming the core equipment for large-scale production of metal curtain accessories.
Technical Core: Equipped with a 32-bit PLC control system and Yaqi servo system, supporting the storage of 10,000 groups of production data. It realizes flexible production of curtain hook bodies, hanging rings, connectors, and other components through 300 action combinations, adapting to various cross-sectional shapes such as round, flat, and square wires.

  • Straightening mechanism: Multiple adjustable straightening wheels ensure that the straightness error of iron wires is <0.3mm, laying the foundation for subsequent bending precision.
• Bending and Cutting Mechanisms:
  • Bending molds: Adjustable positioning columns with a 360° rotating die head, supporting up/down movement and forward/reverse rotation of inner/outer molds, realizing the forming of complex shapes such as U-bends and right-angle bends of curtain hooks;
  • Cutting system: 1.0kW servo-driven cutter, suitable for cutting 2-6mm iron wires, with a cut perpendicularity ≤1° and no burrs, meeting the surface finish requirements.
• Pneumatic Auxiliary System:
  • Number of cylinders: 3, number of solenoid valves: 4, 0.6MPa pressure drives actions such as feeding, discharging, and positioning, with a response time <50ms to ensure the synchronous precision of each process.

(3) Precision and Efficiency Indicators

• Production efficiency: 8-10 pieces/min (standard metal curtain hooks), reaching 20-25 pieces/min for a 200*200mm square frame, which is 5-8 times higher than traditional manual efficiency;
• Forming precision:
  • Bending precision ±0.5mm, ensuring the consistency of hook arcs;
  • Wire feeding precision ±0.5mm, ensuring the fit of hook opening sizes;
  • Angle control ±180°, meeting the strict requirements for hook bending angles.

Ⅲ. Core Advantages of the Equipment

1. Flexible production capability:

• Supports the forming of curtain hooks with 2-6mm wire diameters and any arc. Through the storage of 10,000 groups of data and 300 action combinations, it can quickly switch hook specifications (such as 3mm small hooks and 6mm load-bearing hooks), with a model change time <3 minutes;
• Compatible with materials such as Q235 carbon steel and galvanized iron, meeting the anti-rust and load-bearing performance requirements of curtain accessories.

2. Intelligent control and operational convenience:

• Chinese/English bilingual system, touch screen + button dual-operation mode, supporting production data upload and download. Novices can take up their posts after 1 hour of training;
• Real-time monitoring of parameters such as bending angle and wire feeding length, automatic alarm and shutdown in case of abnormalities, with a rejection rate ≤0.5%.

3. Energy saving and durability:

• Total power 4.8kW, 40% more energy-saving than traditional equipment. With a heat dissipation system, the temperature of core components is ≤65℃, and the continuous operation life of the equipment exceeds 80,000 hours;
• The mold is made of Cr12 alloy (hardness 58-62HRC), with a service life of more than 100,000 times, reducing maintenance costs.

Ⅳ. Application Scenarios: Full Category Coverage of Metal Curtain Hooks

• Standard hook production:
  • Forming of 2-4mm wire diameter curtain hook bodies, ensuring the uniformity of hook opening sizes through ±0.5mm precision control, adapting to the installation needs of different curtain tracks;
  • 180° bending angle combined with a 360° rotating die head realizes the barb process at the hook tail to prevent the curtain from slipping.
• Functional component processing:
  • Hanging ring components: Small ring forming with a diameter of 25-100mm, used for connecting curtain fabrics and hooks, with flatness <0.5mm;
  • Connectors: Flat wire bending forming, supporting multi-piece splicing of curtains, with a load-bearing capacity of more than 5kg.
• Derivative applications:
  • Curtain decorative parts: Special-shaped parts such as wavy lace and spherical hooks, realizing customized production through rapid mold change;
  • Small metal hangers: Meeting the needs of similar products such as home decorative hooks and clothing hooks.
