Automotive seat cushion wire spring bending
Industry Applications
1. Linear Equipment Layout & Process Flow (Total footprint approx. 3.5m × 2.0m)
Coil Loading & Multi-Roller Straightening
Features an X/Y bi-directional multi-wheel straightening mechanism with 14 sets of rollers. The straightening wheels utilize a profile groove design adaptable to φ1.5–3.0mm wire diameters, eliminating internal coil stress and ensuring the flatness and consistency of the spring body.
High-Speed Servo Feeding
Powered by 2 sets of synchronously driven feeding rollers, providing exceptionally high feeding accuracy. The maximum wire feeding speed easily exceeds 50m/min, guaranteeing rapid production cycles.
Precision Servo Cutting
Servo-driven shearing guarantees a flat, deformation-free cut. The cutting length accuracy is strictly controlled to ±0.2mm.
End Hook Forming & Smart Control
End hooks are formed with tight, smooth closures and no misalignment. The PC axis card control system supports Chinese/English interfaces and remote maintenance. No mold changes are required for different products sharing the same wire diameter—just recall the stored program.
2. Core Advantages & Benefits
Double-Head Sync, Doubled Efficiency
Compared to single-head benders, the double-head solution forms both ends of large zigzag springs simultaneously, increasing production speeds by more than 100%.
Customized for Zigzag Springs
Tailor-made for automotive seat wires, foam wires, and double zigzag cushion springs, deeply aligning with specific industry process requirements.
One-Step Forming for Long Bars
Fully capable of handling ultra-long parts from 1.0m up to 3.0m in a single, continuous process of straightening, feeding, bending, and cutting without segmentation.
Perfect Import Substitution
Equipped with premium components (Japanese servos, German reducers, Taiwan bearings). Matches imported performance while providing a distinct advantage in price and responsive after-sales support.
