In the world of stamping automation, the NC servo feed unit stands as a game-changer. Its seamless operation, harnessed through a servo motor and synchronized with the press’s cam signal, has made it the go-to choice for material feeding. This article delves into the workings of the NC servo feed unit, highlighting its advantages and operational principles.
Understanding the NC Servo Feed Unit
The NC servo feed unit operates by synchronizing with the press’s cam signal, ensuring precise material feeding. Its operation boasts user-friendliness, ease of feed distance adjustments, on-the-fly flexibility, and easy installation, all without the need for press feed axis modifications. As a result, it has become the primary choice in the realm of stamping automation.
The Operational Principle
The core principle of the NC servo feed unit revolves around the stamping cycle. It starts at the upper dead center, moves through the lower dead point, and returns to the upper dead point. During the stamping process, the non-processing time is utilized to advance the material coil with a fixed feed pitch, achieving a station-by-station stamping effect.
Enhancing Material Positioning
The contact angle between the die and the material primarily pertains to the forming zone. In contrast, the NC feed unit employs cam angle settings on the press to advance the material in the non-forming area. As the die stamps the material, a die material locating pin securely positions it. Subsequently, the cam angle on the press is used to relax the material within a certain range. This eases the material’s tension, thus enhancing the precision of material positioning during stamping.
Continuous Stamping Efficiency
One significant advantage of the NC servo feed unit is that the feeding zone does not interfere with the forming zone. This enables the use of a continuous stamping method, resulting in high production efficiency.
The NC servo feed unit allows for flexible adjustment of the feeding distance, which depends on the press’s Strokes Per Minute (SPM) and the feeding angle. In cases of delayed feeding, it promptly halts both the press and the feed unit as a safety precaution.
Safety and Efficiency
Not only does the NC feed unit provide rapid and precise material supply and advancement, but it also enhances the safety of the stamping process. It reduces the burden on human labor significantly. The unit encompasses various specifications and features, including material width, thickness, surface requirements, feeding direction, height, speed, material relaxation mode, feed memory, multi-stage feeding capabilities, material end detection, and misalignment feeding, among others.
In conclusion, the NC servo feed unit is a vital component in the world of stamping automation. Its ability to synchronize with the press, optimize material feeding, and enhance safety make it an indispensable choice for businesses aiming to streamline their stamping processes. With its flexibility and precision, this equipment takes material feeding to a whole new level in the realm of stamping automation.
