Substantial technological advancements have disrupted the market of pendulum NC servo feeders. Conventional models, primarily designed for small plate processing, display limitations when applied to larger operations. The fresh approach we will discuss herein promises to transform not only the functionality of these devices but also to extend their processing range significantly.

Dual-Axis Linkage in Servo Feeders: The Challenges

Typical pendulum NC servo feeders operate using a dual-axis linkage, allowing for both horizontal and vertical feed. Employing a pair of straight guide rails on both axes, these devices rely on a solitary nut ball screw and a tiny gap separating the rails. Such a setup, while adequate for small-scale plate processing, experiences issues when it comes to larger operations.

Long plate processing using this traditional structure often leads to restricted horizontal movement and operational jitter. Additionally, the sagging of the ball screw presents another set of obstacles, ultimately undermining the desired effectiveness of these devices.

A New Dawn: The Reinvention of Large-Scale Pendulum NC Servo Feeders

In response to these challenges, the industry has shifted towards an innovative, structurally enhanced design for large-scale pendulum NC servo feeders. This innovation effectively addresses the limitations of the previous models by eliminating screw jitter during horizontal motion, vastly improving machine stability, and ensuring feeding precision for long plate processing.

Advanced Horizontal Structure: Promoting Stability and Precision

In the revamped design, the distance between the horizontal straight guide rails is increased, with an additional middle straight guide rail installed. This layout accommodates multiple nuts on the horizontal ball screw, which in turn, connect to a Mitsubishi servo motor through a horizontal coupler.

The Mitsubishi servo motor powers the horizontal ball screw transmission. During the machine’s operation, the middle horizontal straight guide rail minimises any screw jitter or sag, allowing for smooth, uninterrupted horizontal movement. The widened gap between the nuts on the horizontal ball screw, all connected to the vertical platform, ensures a synchronous and stable operation, thus improving the overall stability of horizontal movement.

Vertical Design Enhancements: Optimising Load Capacity and Motion

In the vertical plane, large-scale pendulum NC servo feeders see an expanded gap between the vertical straight guide rails. To guarantee stable operation, the vertical ball screw and the vertical straight guide rail are equipped with a heavy-load design, ensuring the device remains steadfast during the vertical effective travel.

The Mitsubishi servo motor is linked to the vertical ball screw through a vertical coupler, facilitating smooth vertical motion. This coupling, combined with the wider guide rails and heavy-load design, greatly enhances the stability and accuracy of vertical operations.

In conclusion, these transformative design modifications of large-scale pendulum NC servo feeders represent an evolutionary leap in the field, bringing unprecedented levels of precision, stability, and functionality to large-scale plate processing operations.
