Frequently Asked Questions
Can it integrate with automatic production lines?
Yes, all WyPipe H models support PROFINET/EtherCAT communication protocol, can be integrated with robotic loading/unloading systems and automatic quality inspection stations for lights-out manufacturing.
What is the delivery time for WyPipe H series?
Standard models (H38/H50) have a lead time of 4-6 weeks, while H76/H114 models take 6-8 weeks for production and factory acceptance testing (FAT).
What is the maintenance schedule?
Monthly: Lubricate guide rails and check hydraulic oil level; Quarterly: Calibrate bending angle and inspect die wear; Annual: Servo system maintenance and hydraulic oil replacement.
What is the required power supply?
WyPipe H38/H50: 380V 3-phase 50Hz (30A); WyPipe H76/H114: 400V 3-phase 50Hz (60A), with separate grounding (≤4Ω) and stable voltage (±5%).
What is the springback compensation accuracy?
The built-in material springback database provides 0.1-0.5° automatic compensation, and with optional laser inspection sensors, the compensation accuracy can reach ±0.05° for critical components.
Can it handle square/rectangular tube bending?
Yes, with optional square tube bending dies, WyPipe H can bend square tubes (16×16mm to 80×80mm) and rectangular tubes (20×10mm to 100×50mm) with corner radius ≥2×tube side length.
How much energy can hybrid drive save?
Compared with full hydraulic tube bending machines, the oil-electric hybrid drive saves 25-35% energy, with higher energy efficiency in batch production (≥1000 pieces/day) due to regenerative braking energy recovery.
What materials can WyPipe H series bend?
The WyPipe H series supports carbon steel (Q235/Q355), stainless steel (304/316), aluminum alloy (6061/6063), copper and brass tubes. For high-strength steel (≥450MPa), optional high-hardness tooling is required.
