In the dynamic landscape of stamping automation, the conventional placement of the feeder in front of the stamping die has long been the norm. The feeding roller, with its gripping prowess, orchestrates the forward movement of the stamping strip during a singular motion cycle, rotating at an angle. However, challenges arise when dealing with thinner gauge strips, prone to bending and forming arches before reaching the stamping die, disrupting the feeding process. This quandary has led to an innovative solution – positioning the feeder at the rear of the stamping die, giving rise to the ingenious “pull feeder.”

Overcoming Challenges: The Pull Feeder Advantage

When confronting the hurdles posed by thinner gauge strips, the pull feeder, operating in a reverse fashion, becomes indispensable. Unlike its conventional counterpart, the pull feeder pulls the stamping strip forward in incremental steps, mitigating bending issues and ensuring a seamless feeding process.

Pneumatic Predominance: The State of Pull Feeders

In the current stamping industry landscape, pneumatic pull feeders dominate the scene. These feeders, while effective, demand meticulous adjustments to the press for dimensional precision. The intricate process involves loosening fixed screws, adjusting the cylinder stroke, and painstakingly resecuring the screws. The press undergoes repetitive adjustments and manual fine-tuning, resulting in a precision level of a mere 0.1mm.

Elevating Precision: The Case for NC Servo Feeders

To propel stamping production lines towards unparalleled efficiency and enhance product quality, a paradigm shift is recommended – embracing NC servo feeders for pull-type configurations. This transformative move not only streamlines operational procedures but elevates pulling precision to an impressive 0.01mm.

The Ingenious Mechanics of NC Servo Feeders

The operational brilliance of pull-type NC servo feeders lies in their meticulous configuration. Pulling parameters, including step distance and speed, are effortlessly set through an intuitive touch screen. This data seamlessly travels to the Programmable Logic Controller (PLC) via a transmission line. The PLC, employing intricate program calculations, communicates with the pulse output module, which, in turn, transmits pulses through shielded cables to the servo controller. The AC servo motor, driven by the servo controller, operates with an encoder fixed coaxially at its rear. The encoder transforms speed information into coded signals, creating a closed-loop servo feedback system. This system, a pinnacle of precision, adjusts the speed of the AC servo motor, ensuring a pulling precision of 0.01mm.

Unparalleled Control: Mitsubishi PLCs and Yaskawa Servo Motors

NC servo feeders, champions of precision, exclusively utilize Mitsubishi PLCs paired with Yaskawa servo motors. This combination ensures optimal electrical control configurations, underlining their commitment to high-precision feeding in stamping operations.

Streamlining Adjustments: From Mechanical to Electrical

The pull-type NC servo feeder redefines convenience and reliability in adjustments. It eradicates the need for cumbersome mechanical adjustments, replacing mechanics with electricity and simplifying the mechanical structure. During the production process, strip parameters are effortlessly configured through the touch screen, and the flat strip, guided by the feeder support frame and material stop wheel, is seamlessly positioned. Initiating the machine prompts the pull feeder to execute reciprocating movements, culminating in a flawlessly executed pulling action.

In conclusion, the pull-type NC servo feeder emerges as a game-changer in the realm of stamping automation. Its precision, efficiency, and streamlined adjustments mark a new era, ensuring that stamping production lines operate at the zenith of their capabilities, delivering impeccable results with every cycle.
