SA-DLS-100

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.

Main Components and Configuration

Component: Function & 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.
