Crafting a mechanically automated stamping production line is no simple task. It requires the harmonious synchronisation of multiple elements, with a high-speed roller feeder and a punch press being the critical components. While these systems are designed to accommodate a vast range of products and process molds, it’s not just a matter of swapping out molds. Rather, it requires an intricate sequence of adjustments to the high-speed roller feeder to ensure the seamless and consistent operation of the production line.

This article will delve into the crucial aspects of these adjustments that follow mold replacement on the high-speed roller feeder:

1. Perfecting the Calibration of Feeder Height

The first step after a mold replacement is adjusting the feeder height on the high-speed roller feeder. Equipped with a specific range for adjustments, the roller feeder’s mounting plate simplifies the process of modifying the feeder’s height to align with the new punch mold.

Methodology for Feeder Height Adjustment: To adjust the feeder height, begin by loosening the fixed bolts on the roller feeder’s mounting plate. Next, tweak the height of the adjusting bolt at the base of the plate to suit the height of the newly installed mold.

2. Fine-Tuning the Connecting Rod Length

Following the adjustment of the feeder height, the length of the connecting rod, structured in three segments on the roller feeder, must also be tweaked. This adjustment ensures that when the punch press slide is at its upper dead point, the connecting rod forms a perfect 90° angle with the rocker arm.

3. Adapting the Feeding Step Distance on the Eccentric Disk

Molds come with their own unique process requirements. Hence, adjustments to the step distance on the feeder’s eccentric disk are crucial to meet the specific demands of each mold process.

4. Tailoring the Position and Thickness of the Material Stop Wheel

The material stop wheel is integral during feeding, and its position needs to be adjusted to meet the width requirements of the material. In tandem, the thickness adjustment disk should be altered to match the actual thickness of the material.

5. Modifying the Relaxed Punch Rod Screw Length

The relaxation punch rod apparatus of the high-speed roller feeder, installed on the punch press slide, must also be tweaked to accommodate changes in feeding height. The rule of thumb is to adjust the punch rod length so that when the punch mold guide pin enters the guide hole, it just touches the outer edge of the body relaxation bracket. This adjustment ensures that the roller on the high-speed roller feeder is within 0.5mm of disengaging the material, allowing the material to slide effortlessly between the two rollers.

Adapting to the dynamic needs of various products and processes is not an instantaneous affair. It requires meticulous adjustments and a deep understanding of the interconnected parts that make up the high-speed roller feeder. By mastering these techniques, you can ensure that your automated stamping production line operates with the precision and efficiency it was designed to deliver.
