The servo hydraulic press for stack assembly serves as the core equipment in fuel cell and electrolyzer manufacturing. This high-precision CNC device utilizes servo motors as its drive source. Replacing traditional hydraulic or pneumatic presses, it employs a digital system to precisely control pressure, displacement, speed, and curves during the pressing process. This ensures each individual cell is pressed under highly consistent and controllable process conditions.
PRODUCT DESCRIPTION
Advantages
1. Active Soft-Landing Technology
Specifically designed for the brittle nature of graphite bipolar plates and membrane electrode assemblies (MEAs), the equipment features a soft-landing function. As the pressing head rapidly approaches the workpiece, it automatically switches to a low-speed creeping mode, making gentle contact with the surface. This completely eliminates micro-damage caused by high-speed impact, significantly improving component yield.
2. Dwell Pressure & Stress Relaxation Control
Ensures long-term sealing reliability and internal resistance consistency of the stack. Upon reaching the target pressure/position, the system can stably maintain the set state for extended periods. This allows sufficient stress relaxation of the seals, guaranteeing uniform internal contact pressure within the stack for consistent gas tightness and voltage output.
3. High-Precision Servo Drive
Employs high-end servo motors and precision ball screws (or a servo-hydraulic system), achieving position repeatability accuracy of ±0.01mm and pressure control accuracy of ±0.5%, providing a core guarantee for precision assembly.
4. Intelligent Safety Window Monitoring
Incorporates multiple built-in process "safety windows," ensuring real-time curves strictly follow a preset pressure-displacement envelope. If parameters deviate or trends become abnormal, an immediate alarm and machine stop are triggered, preventing batch quality risks at the source and enabling "zero-defect" production.
