In the realm of stamping manufacturing, progressive dies have become an essential tool for shaping and stamping thin sheets. These dies, equipped with precision-enhancing features, play a crucial role in the accurate feeding and shaping of materials. However, maintaining precision in material feeding is paramount, as any significant deviation can lead to detrimental consequences. It can damage positioning pins, harm the dies, and result in substantial production losses while compromising overall product quality. As a result, the demand for precision and stability in stamping production has surged, leading to the widespread adoption of NC servo feeders in the industry.
In the past, NC servo feeders used a simple yet structurally challenging screw mechanism to adjust the gap between the upper and lower feed rollers. This method, while effective for thinner materials, struggled to maintain consistent gap sizes when dealing with thicker materials (exceeding 3.0mm) or uneven surfaces on raw material strips. Additionally, variations in material thickness along the edges of raw material strips often went unnoticed, resulting in cumulative changes. These cumulative changes caused inconsistencies in the gap at the ends of the feed roller shafts, ultimately leading to material strips veering off course and compromising feeding accuracy. This frequent issue necessitated constant stoppages for adjustments, resulting in problems like misfeeding and entangling, significantly hindering automated stamping production efficiency.
To combat these challenges, we have developed a specialized NC servo feeder tailored for thick sheet materials. This innovative feeder employs pneumatic cylinders for material pressing, a substantial departure from the traditional screw-based approach. The thick sheet NC servo feeder boasts the capability to automatically adjust the gap between the upper and lower conveying rollers based on the thickness of the raw material strip. This revolutionary design dramatically reduces the need for manual intervention, enhancing operational efficiency.
Moreover, the control device’s two cylinders share the same air source, ensuring high uniformity in pressure at both ends. This unique feature minimizes the impact of uneven surfaces on the raw material strip or irregularities in thickness along the edges by allowing the material pressing cylinders to automatically compensate for slight changes in the gap between the upper and lower conveying rollers. As a result, issues such as misfeeding, incorrect feeding, and material misalignment are effectively prevented, fundamentally safeguarding the efficiency of the stamping production process.
In summary, the introduction of specialized thick sheet NC servo feeders with pneumatic cylinder technology marks a significant leap in the stamping manufacturing industry. These feeders offer precise and consistent material feeding, reduce the need for manual adjustments, and ensure smooth and efficient production. As the industry continues to evolve, innovations like these play a crucial role in maintaining high-quality standards and meeting the growing demand for precision in stamping production.
