The evolution of stamping processing is unstoppable, moving steadily towards enhanced precision, improved efficiency, and comprehensive automation. This remarkable trend intensifies the need for advanced punch press feeders, instigating a constant phase of renewal and transition. Starting from the reliable, first-generation air feeders to the more advanced second-generation roller feeders, we have witnessed remarkable improvements in accuracy, stability, and automation. Despite these leaps, we’re still grappling with the challenge of meeting ever-evolving precision stamping demands. Existing machines demonstrate an imperfect synchronisation of material holding, feeding actions, and punch press points. Additionally, the calibration process for feeder machines remains rather complex, increasingly failing to meet the demands of modern stamping production.
Emergence of the Game-Changing NC Servo Feeders
In response to these persisting challenges, the third generation of NC Servo Feeders has stepped onto the stage of the punch press industry. These machines, powered by Mitsubishi Servo Motors and integrated with Mitsubishi PLCs, feature 7-inch high-precision touch screens for effortless control. Linked to the punch press cams by signal lines, they ingeniously use the timing of the crankshaft’s path to perform feeding, repositioning, and clamping operations, achieving seamless synchronization with the punch press. The NC Servo Feeder’s touch panel simplifies operations by enabling easy setting of the feed’s length, frequency, and speed.
Bridging the Gap: Advantages of NC Servo Feeders
The NC Servo Feeder skillfully addresses the frequent limitations of earlier feeding machines. It eliminates issues like delayed and inaccurate feeding by optimizing the entire process through a direct connection with the crankshaft cam. This enhancement broadens the feeder’s application range while improving feeding precision, automation, and stability.
In Sync with the Punch Press: A Detailed Look
The NC Servo Feeder works in perfect unison with the punch press, initiating feeding between 240° and 90° clockwise on the punch press crankshaft. At the 240° mark, the feeding action commences, propelling the feeder smoothly and instantly in line with the current angle of the punch press. Feeding concludes when the crankshaft reaches 90°, thus maximizing the entire feeding interval. In addition, all NC Servo Feeders come equipped with a standard relaxation feature. Typically, this feature utilizes a solenoid valve to control a pneumatic cylinder-driven relaxation mechanism. This mechanism usually kicks in an angle past the end of the completed feed and before the mold fully contacts the material, effectively eliminating accumulated errors and ensuring long-term feed precision stability.
In conclusion, the advent of NC Servo Feeders marks a significant milestone in the stamping processing industry, effectively bridging the gap between technological advancements and ever-increasing precision demands. This innovative solution optimizes stamping processing by offering improved precision, increased automation, and enhanced stability.
