Working Principle (English Translation)
The working principle of the air feeder is based on a pneumatic control system, using compressed air as the power source, achieving automatic clamping, feeding, and releasing cycles of materials through cylinders and solenoid valves, synchronized with the press operation. The specific process is as follows:
- Preparation Stage: Material enters the feeder's inlet from the uncoiler or straightener. The air source provides 0.5-0.8MPa compressed air, entering the cylinder for drive preparation.
- Clamping Stage: When the press slider rises to the top dead center, the solenoid valve opens, and compressed air pushes the fixed clamp and movable clamp to grip the material. The fixed clamp force ensures stability, and the movable clamp force provides traction power.
- Feeding Stage: The cylinder pushes the feed arm forward, feeding the material into the press mold according to the set length. The support uses linear bearings to ensure rapid displacement, no noise, and high wear resistance. Feeding accuracy is controlled by the adjustment valve, up to ±0.05mm.
- Releasing Stage: When the press slider descends to start stamping, the solenoid valve switches, and the cylinder releases the clamps, loosening the material. At the same time, the relaxation solenoid valve activates to prevent material rebound or jamming.
- Return Stage: The cylinder resets, preparing for the next cycle. The entire process is linked with the press's cam signal to achieve automated continuous feeding.
This principle is suitable for automated processing, especially for new strong models for thicker materials. Maintenance is simple, requiring only regular checks of the air source and bearing lubrication. In professional terms, this is an "Intermittent Feeding Mechanism", emphasizing the rapid response of pneumatic cylinders and light load characteristics.
