Tube production line SJZ series

Pipe Manufacturing Plant tractor equipment ‌Ensuring Continuous Production: By gripping extruded tubes/profiles and applying steady pulling force, the puller uniformly draws them from the die exit and conveys them to downstream processes, guaranteeing continuous line operation‌ Dual-puller systems are particularly crucial: While one puller head grips and moves the tube, the other can return to the starting position, enabling seamless alternating operation. This significantly minimizes downtime and boosts production capacity‌ Controlling Product Quality: Precise adjustment of pulling force and speed effectively prevents tube bending or deformation caused by gravity or uneven stress‌ For instance Four-track pullers distribute force evenly to avoid crushing damage to thin-walled tubes Designs incorporating rubber belts/pads provide sufficient friction while minimizing surface scratches, preserving the tube's appearance‌ Enhancing Dimensional Accuracy: Puller speed must be strictly synchronized with extrusion speed. Excessive pulling speed causes stretching, thinning, or breakage; insufficient speed leads to material accumulation and deformation‌ Modern pullers utilize servo motor drives and PLC control systems to achieve millimeter-level speed synchronization, ensuring tube parameters (wall thickness, diameter) meet standards‌ Reducing Scrap Rate and Economic Costs: Continuous pulling reduces waiting time during non-extrusion cycles. Combined with automatic cutting, it enables precise length control, minimizing material waste‌ It also avoids downtime or errors caused by manual intervention, comprehensively improving the finished product rate‌
