    Inverted Wire Drawing Machine (Inverted Bull Block)

    Wire drawing machine for diameter reduction and take-up of drawn wires
    • Drawing speed 300m/min
    • Capstan diameter 560mm
    • Inlet wire diameter 3.0-5.0mm

    Achieving ultra-fine wire diameters often starts with a single-pass drawing process capable of reducing metal wire to below 0.01 mm, with dimensional tolerances kept within ±0.01 mm. The inverted bull block wire drawing machine is a widely used solution for this type of precision work, especially when processing low-carbon steel wires such as Q195, Q235, 1008, and 1006, along with other soft and ductile metal materials.

    Applications

    Commonly used in the production of screws, nuts, washers, nails, wire mesh, bundling wire, and general-purpose iron wire.

    • Automatic and intelligent control system with integrated PLC and touchscreen; adjusts drawing speed and tension for continuous, low-intervention operation
    Main Components and Configuration
    • Pay-off stand: Single-layer pay-off stand with automatic tension and deviation control to prevent wire entanglement. Includes auto-detection for wire breakage and tangle, enabling non-stop operation. Supports multiple pay-off methods: active or passive.
    • Drawing unit: Core drive system with variable frequency motor and reducer. Equipped with double-layer capstans coated with tungsten carbide and a die box. Driven by a frequency converter to achieve precise wire take-up.
    • Wire diameter range: The 600 type handles wires from φ8.0 down to φ4.5, while the 800 type processes from φ14.0 to φ7. Additional configurations are available to match different wire specifications and production needs.
    • Power output: Depends on capstan size
    • Control unit: Siemens PLC system with integrated HMI interface for real-time monitoring of drawing force, speed, weight, and specification parameters.

    Single block wire drawing machines are suitable for drawing low-carbon steel wire, such as Q195, Q235, 1008, and 1006, into thinner diameters. They’re often used in the production of screws, nuts, washers, nails, mesh, tie wire, and other wire-based products that require consistent diameter and surface finish.

    • Our single block wire drawing machines use high-durability dies made from tungsten carbide, PCD (polycrystalline diamond), or nano-coated materials. Dies can be replaced quickly to adapt to different wire diameters.
    • Automation is supported through an integrated PLC and touchscreen interface, enabling real-time adjustment of drawing speed and tension for smooth, continuous operation.

    Each coil takes approximately 50 seconds to complete the drawing process, depending on wire size and production setup.

    Switching to better-quality wire, reducing winding tension, or replacing worn guide rollers can help resolve breakage issues. Regular maintenance of wire path components also helps prevent disruptions.
