Unraveling the Limitations of NC Feeders at 250 Strokes Per Minute
In the realm of stamping production, the NC feeder stands as one of the three widely utilized feeding devices. Employing electromechanical control for feeding, it has been a staple in the industry. However, a significant drawback surfaces when the stamping press accelerates to 250 strokes per minute – the NC feeder falters in achieving precise feeding for every stroke.
The Pitfalls of Electromechanical Control at High Speeds
As the press surges to 250 strokes per minute, each stroke lasting a mere 0.24 seconds, the electromechanically controlled intermittent feeding mechanism faces constraints. With stamping strokes confined to 25mm to 30mm in high-speed presses and the mold relying on guide pins for material positioning, the NC feeder becomes incapacitated during the upper mold’s contact with the material.
This results in a drastic reduction of actual feeding time to about 40% of the stroke time (0.09 seconds). Considering the intricate demands of the electronic control system, encompassing response time, signal processing time, motor response time, acceleration and deceleration time, and system feedback time, the control system’s requirements far surpass the available time for each stroke. The consequence is a failure to meet the criteria for high-speed and high-precision feeding, with potential signal errors posing a threat to the integrity of the stamping dies.
Embracing the Solution: Gear Feeders for High-Speed Precision
In addressing the challenges posed by high-speed presses and the imperative for swift feeding, an alternative feeding solution emerges – the gear feeder. Meticulously engineered as a synchronous feeding device for high-speed applications, the gear feeder operates solely through mechanical linkage, bypassing issues associated with response times during feeding.
Mechanized Precision: The Advantages of Gear Feeders
The gear feeder, with its reliance on a cam structure, orchestrates critical movements seamlessly, ensuring exceptional repeatability in actions. This mechanical linkage not only eliminates concerns about response time but also guarantees the consistent precision of various movements during the feeding process. This adaptability enables the gear feeder to effortlessly cater to progressive feeding requirements across different speeds and precision levels.
Versatility in Action: Tailoring to Speed and Specification Demands
What sets the gear feeder apart is its adaptability to various speeds and feeding specifications. This makes it particularly suited to the high-speed feeding demands synonymous with stamping presses. As an indispensable solution in stamping production, the gear feeder excels in meeting the precision and speed prerequisites that the NC feeder struggles to fulfill.
In conclusion, the gear feeder emerges as a superior choice for stamping operations necessitating high-speed and high-precision feeding. Its mechanical precision, coupled with adaptability to diverse specifications, positions it as the go-to solution for those seeking to optimize performance in the fast-paced realm of stamping production.
