Automotive seat grid plate bending
Industry Applications
1. Integrated Island Layout & Process Flow (Total footprint approx. 10.0m × 3.5m)
Multi-Axis Independent Pay-off & Multi-Channel Straightening
Configured with 5–7 independent servo active pay-off racks (load capacity 20-500kg), each with independent tension control to ensure synchronous unwinding without interference or tangling. Each feeding route is equipped with an independent straightener, perfectly eliminating internal coil stress to meet strict straightness requirements for subsequent grid positioning.
Servo Fixed-Length Feeding & Wire Threading Positioning
Horizontal wires accurately pass through the center plastic tubes or positioning guide sleeves, while vertical wires are automatically arranged according to grid spacing. Positioning accuracy directly determines grid forming quality. Select high-end machines are equipped with visual positioning detection for dual assurance.
Automatic End Hooking & Knotting Lock
The hooking/knotting mechanism is deeply integrated into the host. The ends of the horizontal wires are precisely hooked and fastened onto the plastic-coated vertical wires, while the vertical wire ends undergo secondary bending. Certain configurations utilize a flip-plate knotting mechanism to complete bending and structural locking in one step.
Smart Security & One-Step Direct Discharging
The dual-display bus control system supports one-click program recall for setup; the entire machine is fully enclosed in sheet metal and equipped with 3 safety rolling doors. The final output is a complete, high-precision grid frame, completely eliminating subsequent manual assembly processes.
2. Core Advantages & Benefits
Multi-Axis Sync, One-Step Output
Dozens of axes operate synchronously across multiple stations, completing horizontal hooking and vertical forming in one step, fundamentally replacing the tedious "single-wire bending + manual threading & knotting" multi-process mode.
High Consistency & Precise Dimensions
Full servo CNC precision control ensures highly consistent grid spacing and hooking angles. Its ±0.2mm repeat positioning accuracy perfectly meets the stringent tolerance requirements of automotive seats.
Damage-Free Plastic-Coated Wire Forming
Optimized bending mechanisms with customized tooling, or non-destructive solutions using rotary cylinders and cam followers, perfectly accommodate plastic-coated wires, ensuring the coating remains completely undamaged throughout processing.
Adjustable Width & Import Substitution
Cylinder-driven bending station spacing is dynamically adjustable to easily adapt to various vehicle models. Performance matches South Korean equipment at just 60% of the cost, making it the preferred choice for mainstream seat suppliers.
