Flux-cored wire drawing machine
The flux-cored wire drawing machine is a key equipment for producing flux-cored wire. Its core task is to accurately reduce the tubular wire blank filled with flux to the required final size through multiple drawing passes, while ensuring that the internal flux powder is evenly distributed and does not leak.
| Component/Technology | Core functions and features |
Technological evolution/innovation |
| Wire drawing machine and die frame | Provides pulling power to plastically deform and reduce the diameter of the welding wire through the die. | From fixed drawing dies to multiple sets of die frames for sequential drawing, or using roller die combinations to reduce friction |
| Tension control system | Keep the tension stable in each drawing stage to prevent wire accumulation and wire breakage. | In the early days, it relied on manual experience, but now it uses mathematical models and optimal control theory to design tension feedback regulators to achieve automatic adjustment. |
| Reel and constant speed control | Winding the drawn wire. As the winding diameter increases, the wire speed is kept constant. | The innovation lies in the constant speed control component, which can automatically adjust the speed according to the real-time diameter of the reel to ensure the same quality of the same batch of welding wire |
| cooling system | Take away the heat generated during the drawing process to prevent the wire from overheating and affecting the quality | The utility model patent emphasizes the importance of the water cooling box and cooling mechanism to effectively control the temperature to ensure the quality of the welding wire. |
| Automation control (PLC/inverter) | Coordinate the entire system to run synchronously to achieve high-speed and stable production | Apply PLC, frequency converter (such as Orei F series) and human-machine interface (touch screen) to achieve automatic control |
