Features
Designed for rapid, repeatable bending of Φ6.35–9.52mm tubes (customizable), this pneumatic-servo system achieves ≤5-second bend cycles with ±0.1mm U-shape accuracy and <15% ovality. Integrates Mitsubishi PLC+HMI controls, 7.5kW hybrid power (hydraulic + servo), and tool-free mold swaps – optimized for copper/aluminum refrigeration lines, automotive tubing, and micro-fluidic systems.
Ultra-Flexible Tube Processing
Handles Φ6.35–25mm customizable diameters (wall thickness ≤35%) with 3–5 bends/cycle. Pneumatic clamping + servo-driven feed ensures zero-slip material handling at ≤0.5% scrap rate.
Closed-Loop Bending Precision
Mitsubishi FX5U PLC monitors force-feedback to maintain ±0.1mm bend angle under 6–10MPa hydraulic pressure. Real-time ovality correction via mandrel-roller synchronization.
Pneumatic Saw-Blade Cutting Integration
0.4–0.6MPa air-powered cutting (≤1s cycle) ensures burr-free tube ends with ±0.05mm length tolerance. No secondary trimming required.
One-Touch Tooling Adaptability
Quick-release mold system swaps bending dies in <2 minutes. Preloaded recipes on 10.1-inch Mitsubishi HMI enable batch changes without reprogramming.
