Pneumatic feeders, although an older technology, continue to hold a place in the market due to their affordability. While roller feeders and NC servo feeders are now more popular for their advanced capabilities, pneumatic feeders are still preferred for scenarios with low stamping volumes and minimal precision requirements.

Why Choose Pneumatic Feeders?

Pneumatic feeders offer several advantages in specific use cases. They are cost-effective and simpler to maintain, making them an ideal choice for operations where the high cost of advanced feeders cannot be justified. Understanding these benefits can help you determine if a pneumatic feeder is the right fit for your manufacturing needs.

Receiving and Checking Installation Accessories

When customers opt to install pneumatic feeders themselves, the delivery method varies based on the model. Smaller models (below 7C) are shipped via courier, while larger models are sent via logistics due to the floor stand requirements. Upon receipt, it is crucial to verify that all necessary installation accessories are included. The standard kit typically contains:

  • Mounting Plate: Secures the feeder to the press table.
  • Mounting Screws: Used to affix the mounting plate.
  • Three-Point Combination Unit: Handles water filtration, pressure regulation, and oil lubrication.
  • High-Pressure Hose: Connects the feeder to the external air source.
  • Feeding Rod: Controls the feeding timing.
  • Sealing Rings: Prevent air leaks and ensure feeding accuracy.

Step-by-Step Installation Process

1. Determine Installation Position

First, decide on the installation position based on your stamping process requirements. The pneumatic feeder can be used for both feeding and pulling materials, so the location will depend on your specific operational needs.

2. Secure the Mounting Plate

Place the mounting plate on the side of the press where the feeder will be installed. Mark the screw hole positions, drill the necessary holes, and securely fix the mounting plate in place.

3. Install the Feeder Body

Align the main body of the pneumatic feeder with the mounting plate and secure it. Ensure it is firmly attached and properly positioned.

4. Set Up the Feeding Rod Device

Attach the feeding rod device to the press table in alignment with the floating rod on the feeder’s main body. Proper alignment is crucial for accurate feeding.

5. Connect the Three-Point Combination Unit

Install the three-point combination unit at a suitable location on the lower part of the press body using screws. Connect the external air source to the unit’s inlet, attach the high-pressure hose from the outlet to the feeder, and fill the unit with lubricating oil.

Final Steps and Testing

After completing the installation, double-check all connections and ensure everything is securely fastened. Turn on the air source and test the pneumatic feeder to verify that it operates correctly. Adjust the feeding rod as needed to match the desired feeding time and precision.

Maintenance Tips for Pneumatic Feeders

Regular maintenance is essential for the optimal performance of your pneumatic feeder. Periodically check for air leaks, ensure the lubricating oil is at the correct level, and inspect the sealing rings for wear. Timely replacement of consumable parts will prevent feeding inaccuracies and prolong the feeder’s lifespan.

Conclusion

Pneumatic feeders remain a viable option for many manufacturing operations due to their cost-effectiveness and simplicity. By following the detailed installation steps and maintaining the equipment properly, you can achieve reliable performance even with this older technology. Whether you are feeding or pulling material, a well-installed pneumatic feeder can meet your needs efficiently.
