Automotive seat grid plate bending
Project Overview
This machine synchronously feeds multiple coils of wire and uses 35–58 axes of simultaneous motion to form a complete mesh skeleton in one cycle. S‑shaped, W‑shaped, or wave‑shaped mesh is produced inline while end hooks and knots are completed simultaneously. Yield rate ≥99.8% – a direct replacement for imported equipment.
Ideal for automotive seat backrest wire meshes, cushion support grids, and lumbar support skeletons. Integrated process: multi‑coil pay‑off → independent straightening → servo feeding → transverse wire positioning → longitudinal wire arrangement → multi‑axis synchronous bending → end hook/knotting → finished mesh unloading.
5–7 Independent Pay‑offs & Straightening
Each coil (100–300kg) has its own servo‑driven pay‑off with independent tension control. Separate straightening units per wire path eliminate coil memory, suitable for φ1.5–6.0mm steel or plastic‑coated wire.
Precise Transverse & Longitudinal Positioning
Transverse wires are guided through plastic tubes; longitudinal wires are spaced automatically. Optional vision inspection ensures grid alignment before forming.
35–58 Axis Synchronous Bending & Knotting
All servo axes work simultaneously to bend transverse wire ends and lock longitudinal wires with hooks/knots. Completes S‑, W‑, or wave‑shaped mesh in one cycle – no manual assembly.
Repeatability ±0.2mm & Coating Protection
CNC closed‑loop control ensures mesh spacing and hook angles are consistent. Tooling design prevents damage to plastic coating – suitable for coated wires.
Program‑Based Changeover & Remote Support
Recall product parameters and swap tooling quickly. Dual‑display PC control with independent programming for each bending station. Ethernet remote diagnostics.
Yield ≥99.8% – Proven at Major Seat Suppliers
30% higher efficiency than traditional processes. Fully enclosed safety guarding with remote operation. Performance comparable to Korean imports at 60% cost – already used by Adient, Lear, Faurecia.
