In the realm of stamping production, the seamless operation of machinery is paramount. One crucial component in this process is the NC servo feeder. Whether it’s the initial setup or transitioning to a new stamping die, operators must execute a series of meticulous adjustments to ensure optimal performance. Let’s delve into the essential adjustments required to fine-tune the NC servo feeder for efficient and smooth stamping production.

Servo Feeder Height Adjustment

Aligning the feeding height of the NC servo feeder with the mold line height is imperative for flawless operation. Here’s how to execute this adjustment effectively:

  1. Loosen Screws: Begin by loosening the outer hexagon M16 screws on the feeder fixing plate.
  2. Adjust Bottom Screw: Next, loosen the screw cap at the bottom of the feeder and adjust the bottom M16 screw. Clockwise rotation lowers the feeder, while counterclockwise rotation raises it.
  3. Align Feeding Height: Ensure the feeding height matches the mold entry height for seamless operation.

Servo Feeder Material Pressure Spring Adjustment

Proper tension adjustment of the material pressure spring is vital to prevent slippage and ensure accurate feeding. Follow these steps for optimal adjustment:

  1. Locate Spring: Identify the material pressure spring (located at the front for small-sized servo feeders and at the top for large-sized ones).
  2. Adjust Tension: Adjust the tension until the material and rollers do not slip, ensuring the pressure is appropriate.
  3. Optimize Pressure: Avoid excessive pressure to prevent material deflection or deformation, and ensure accurate feeding.

Servo Feeder Material Stop Wheel Width Adjustment

Adjusting the width of the stop wheel to match the material is crucial for smooth operation. Here’s how to accomplish this adjustment:

  1. Loosen Screw: Begin by loosening the stop wheel screw and relaxing the rollers on the NC servo feeder.
  2. Insert Material: Insert the material between the rollers, preferably placing it in the middle.
  3. Adjust Stop Wheel: Move the stop wheel to the sides of the material, leaving a gap of about 0.2mm, then tighten the screw for secure positioning.

Servo Feeder Start Signal Adjustment

The adjustment of the feeding start signal is pivotal for synchronized operation with the punch press. Follow these steps for precise adjustment:

  1. Configure Signal Lines: Refer to the mechanical and electrical circuit diagram for configuration and connection of feeding signal lines and relaxation signal lines.
  2. Set Feeding Start Signal: Adjust the feeding start signal to synchronize with the punch press, ensuring feeding begins when the upper and lower dies are disengaged.

Servo Feeder Relaxation Angle Adjustment

Coordinating relaxation time with the die is essential for optimal performance. Here’s how to adjust the relaxation angle effectively:

  1. Understand Timing: Relaxation starts when the upper die guide pin inserts into the material and stops before the upper die guide pin leaves the material.
  2. Refer to Diagram: Consult the timing diagram for the relaxation device to ensure precise adjustment.

Precautions for Servo Feeder Adjustment

Prioritize safety when conducting adjustments on the servo feeder. Follow these precautions:

  1. Power Off: Always turn off the power to the servo feeder before terminating work or making adjustments.
  2. Air Compressor: If inspecting or repairing pneumatic devices, stop the air compressor and release residual air.
  3. Professional Assistance: Seek professional assistance for checking or adjusting electromagnetics, pressure devices, starters, etc.

Adjustment of Supporting Equipment

Ensure seamless integration with supporting equipment for optimal performance:

  1. Start Other Equipment: Initiate other equipment in the production line, such as material racks and straightening machines, and verify compatibility and speed alignment with the NC servo feeder.

Setting Servo Feeder Parameters

Accurate parameter settings are crucial for efficient operation:

  1. Touchscreen Configuration: Utilize the servo feeder touchscreen to set parameters such as feeding length and speed according to production requirements.
  2. Counting Setting: Set the counting parameter based on production orders to ensure automated stopping and alarming once the set quantity is reached.

Trial Run

Conduct a trial run to verify proper functioning:

  1. Single-Stroke Mode: Set the punch press to single-stroke mode and confirm the feeding pitch and timing.
  2. Automatic Function: Initiate the automatic function of the feeder to commence automated feeding production seamlessly.

In conclusion, meticulous adjustment of the NC servo feeder is essential for optimizing stamping production efficiency. By adhering to these guidelines, operators can ensure smooth operation and maximize productivity in the stamping process.
