Mastering the Use of NC Servo Feeders with Shearing Machines: A Complete Guide

The NC servo feeder is a versatile and essential component in automated manufacturing processes. Designed to enhance efficiency, it can seamlessly integrate with punch presses to create automated stamping production lines or work alongside shearing machines for cutting coil materials. This guide explains how NC servo feeders function in coordination with shearing machines and outlines the step-by-step operating procedures.

Understanding the NC Servo Feeder’s Functionality

When paired with a punch press, the NC servo feeder operates under the control of the punch press. Conversely, when used with a shearing machine, the NC servo feeder takes charge of the shearing process. After advancing the material to the desired position, the feeder sends a signal to the shearing machine to initiate cutting. This dynamic interaction ensures precision, reduces material waste, and boosts production efficiency.

Step-by-Step Operating Procedure for NC Servo Feeder with Shearing Machine

1. Powering On and Manual Operation

The initial setup involves powering on the NC servo feeder and performing manual operations to position the material correctly. Follow these steps:

1. Activate the System: Turn on the power and access the touchscreen interface.
2. Engage Manual Mode: Tap the manual button on the touchscreen to enable manual operation.
3. Control Material Movement: Use the “forward” and “reverse” buttons to adjust the material’s position. Ensure precise alignment for accurate cutting.
4. Check Shearing Machine Position: Confirm that the shearing machine is at the top dead center (marked as X0 in the closed state) before proceeding.
5. Remove Material Burrs: Press the manual shearing button on the touchscreen (or use an external button connected to X1 on the PLC) to eliminate burrs. Once cutting is complete, the shearing machine automatically returns to the top dead center.

2. Switching to Automatic Mode

After completing the manual setup, transition to automatic mode for continuous operations:

1. Initiate Feeding Stroke: In manual mode, press the “start” button to perform one feeding stroke.
2. Enable Automatic Mode: Select the automatic mode on the touchscreen and press the “start” button to begin the automated cycle.
3. Monitor the Shearing Cycle:The shearing machine cuts the material and pauses momentarily to ensure adequate shearing time.The machine returns to the top dead center after each cut.
4. Facilitate Continuous Feeding: The NC servo feeder advances the material, pauses briefly (adjustable delay), and signals the shearing machine to execute the next cut.

This synchronized process allows for uninterrupted operations, maximizing productivity.

Detailed Overview of the Automatic Cycle

In automatic mode, the NC servo feeder and shearing machine work together seamlessly to maintain a continuous production flow. Here’s how the cycle unfolds:

1. Initiate Shearing: The shearing process begins with a programmed delay for precision.
2. Return to Top Dead Center: After cutting, the shearing machine resets to the X0 position (closed state).
3. Advance Material: The NC servo feeder moves the material forward and signals the shearing machine.
4. Perform Cutting: The shearing machine executes the cut with another programmed delay to ensure accuracy.
5. Reset and Repeat: The shearing machine returns to the X0 position, and the feeder advances the material again, repeating the cycle.

Benefits of Using NC Servo Feeders with Shearing Machines

• Enhanced Precision: The feeder ensures consistent material positioning, reducing errors.
• Increased Efficiency: Automation streamlines operations, cutting down on cycle time.
• Material Savings: Accurate feeding and cutting minimize waste.
• Versatility: The NC servo feeder adapts to various production requirements, making it a valuable asset in diverse manufacturing setups.

Conclusion

Integrating an NC servo feeder with a shearing machine revolutionizes the manufacturing process by delivering precision, efficiency, and reliability. By mastering the operational procedures outlined in this guide, you can unlock the full potential of your automated production line. Whether in manual or automatic mode, the NC servo feeder ensures seamless material handling, making it an indispensable tool for modern manufacturing.
