Roller feeders play a pivotal role in the world of stamping production, and their significance lies not only in the diversity of types based on material width and pitch but also in the distinction between low-speed and high-speed models concerning the feeding speed. Understanding these distinctions can help stamping clients optimize their production processes and enhance productivity significantly.

The Difference in Speed

The classification of roller feeders into low-speed and high-speed models stems from their feeding capabilities. The low-speed roller feeder operates at a maximum speed of 190 cycles per minute, ideally suited for traditional punches and low-speed pneumatic precision punches, catering to medium to low-speed stamping production needs. In contrast, the high-speed roller feeder achieves an impressive rapid speed of up to 600 cycles per minute, making it a perfect fit for high-speed presses in medium to high-speed stamping production.

Operational Principle Unveiled

Irrespective of whether it’s a low-speed or high-speed model, the operational principle remains consistent. The roller feeder functions by installing an eccentric disk on the output shaft of the punch or crankshaft. Power transmission occurs through universal joints, pull rods, rocker arms, and the output shaft. This mechanism drives the reciprocating rotation of the feeding drum, enabling the material to be fed through the interaction of the feeding drum and gear set in a roller-pressing manner. A brake system is incorporated to dampen the inertia motion of the feeding drum. When the feeding reaches the designated position, the roller feeder, positioned on the slide of the punch, relaxes the pressing and releasing device in a timely manner. This allows the stepped-axis relaxation shaft to lift the feeding drum, ensuring precise material positioning for accurate stamping.

Unraveling the Distinctions

Stamping clients often ponder upon the significant difference in feeding performance between low-speed and high-speed roller feeder models, given their identical operational principles. The answer lies in the comprehensive improvements that the high-speed roller feeder undergoes in various aspects:

  1. Enhanced Material Selection and Processing Techniques: The high-speed roller feeder utilizes top-notch materials and refined processing techniques. For instance, it incorporates Japanese NSK bearings and relies on original Swiss-imported brands for one-way and reverse devices.
  2. Structural Advancements: The high-speed roller feeder comes with several structural enhancements, such as the addition of a transparent cover on the feeding side. This feature enables visual observation of the material’s threading condition, providing a clear working environment.
  3. User-Friendly Clamping Mechanism: The clamping of the transmission side is made simpler and more user-friendly with a semi-split sleeve. Additionally, the adjustment of the feeding stroke can be precisely and definitively fine-tuned without any gaps, ensuring smooth operations.
  4. Anti-Reverse Mechanisms for Precise Feeding: Both the feeding and material clamping roller rotations are equipped with anti-reverse mechanisms, guaranteeing accurate feeding. Moreover, the adjustment system for the material-contacting roller surface allows for more precise fine-tuning, further optimizing the performance.

The Path to High-Speed Stability

Thanks to these material selection, processing, and structural improvements, the high-speed roller feeder achieves outstanding feeding performance at high speeds while maintaining stability. This technological advancement in the world of stamping production opens up new avenues for increased productivity and improved efficiency.

In conclusion, understanding the distinctions between low-speed and high-speed roller feeders can be a game-changer for stamping clients aiming to boost their production capabilities. The high-speed roller feeder, with its advanced features and precision, takes the productivity of stamping production to new heights. By embracing these technological advancements, businesses can revolutionize their production processes and stay ahead in the competitive landscape of the stamping industry.
