In the realm of the stamping industry, one name stands tall when discussing feeders – the roller feeder. This feeding marvel holds an esteemed position due to its extensive adoption, reliable performance, and cost-effectiveness. What sets it apart is its self-sufficiency, making it a top choice among automated equipment options for stamping industry players.
Delving into the Mechanics of the Roller Feeder
While the roller feeder finds its place as a stalwart in the stamping world, its inner workings often remain a mystery. Understanding its intricate motions and operations can have a profound impact on how customers utilize, maintain, and repair this remarkable device.
The roller feeder is ingeniously designed without an internal power unit. Instead, it draws its power from the output shaft of a press to execute its precise feeding actions. Here’s how it works: an eccentric disc mount is fixed to the end of the press’s output shaft. When the press is in operation, a sequential chain of components – including the eccentric disc, universal joint, connecting rod, rocker arm, drive shaft, and unidirectional mechanism – collaborates to create motion. This motion propels the lower roller into a cyclic rotation. This rhythmic rotation, occurring at predetermined intervals, propels the material forward.
Seamless Integration into the Stamping Process
When combined with a press, the roller feeder’s functionality comes to life. The press’s downward motion initiates the process by activating a relaxation lever connected to the roller feeder’s body. This motion, in turn, causes the relaxation support to pivot, lifting its lower end at an angle. As a result, the adjustment seat, which is supported by this framework, rises, creating space for the material to be inserted between the upper and lower rollers. The gap between these rollers can be finely adjusted by manually turning an eccentric shaft using a handwheel. Once the desired distance is achieved, a locking bolt secures the position.
As the press’s slide moves upward, the material, influenced by the roller feeder’s compression spring, causes the adjustment seat to descend, effectively clamping the material between the rollers. This process concludes the material insertion stage. The press’s output shaft then propels the eccentric disc of the roller feeder, initiating the cyclic rotation of the lower roller. The harmonious rotation between the upper and lower rollers drives the incremental feeding action, a hallmark of the roller feeder’s precision.
Unmatched Speed and Precision
The roller feeder’s mechanically driven output shaft mechanism empowers it to achieve remarkable feeding speeds, reaching frequencies of up to 600 cycles per minute. Its installation and operation are straightforward, requiring mere attachment to a press’s side and connection to the output shaft for automated production. Notably, the integration of precision unidirectional and reverse mechanisms, along with advanced electromagnetic braking, guarantees feeding accuracy to within an astounding ±0.02mm.
The Verdict: A Masterpiece of Feeding Apparatus
With its compact and accessible structural design, the roller feeder stands tall as an industry-preferred feeding solution. Its ability to harness mechanical power, coupled with its unparalleled accuracy, cements its dominance in the stamping industry. As stamping processes continue to evolve, the roller feeder remains an ever-reliable companion, ensuring efficient and precise material feeding with every cycle.
