Precision manufacturing relies heavily on the seamless integration of various components, and when it comes to automated stamping production lines, metal sheets play a pivotal role. Before these sheets undergo stamping, a crucial step is employed – leveling. This process is instrumental in eliminating internal stresses within the metal sheets and ensuring their optimal flatness. At the forefront of the leveling process, a material rack unfurls the metal coil and directs it into the leveling machine. Subsequently, a feed mechanism propels the leveled sheet into the stamping die, completing the automated production cycle.
In recent times, the NC servo feeder has emerged as a game-changer in the world of stamping. It has gained widespread adoption among stamping professionals owing to its user-friendly operation, exceptional feeding precision, and its remarkable ability to handle thick sheet materials, which roller feeders or air feeders often struggle with. However, like any innovation, NC servo feeders are not without their challenges. Two significant issues have been identified, and we are here to address them comprehensively.
Issue 1: Rigid Power Transmission
The primary concern with the existing NC servo feeders lies in their power transmission mechanism for raising and lowering the roller. It’s rigid and inflexible, which during operation can lead to misalignment, causing jamming or uneven vertical positioning. This, in turn, results in inaccurate feeding, which has been a source of frustration for many users.
To tackle this issue head-on, we’ve implemented targeted structural improvements. At the crucial juncture where the NC servo feeder’s lifting power source relaxation cylinder meets the plate it provides, we’ve introduced a floating joint. This innovation replaces the previous rigid connection with a flexible and active one, greatly enhancing the feeder’s mechanical performance and ensuring a reliable connection. The result? A feeder that prevents jamming or misalignment due to non-vertical alignment, guaranteeing precise feeding.
Issue 2: Material Arc and Feeding Precision
The second major issue arises when the NC servo feeder is tasked with feeding relatively thick metal sheets, typically in the range of 2-4.5mm. During this process, a long material arc forms between the feeder and the leveling machine. If this arc is not sufficiently long, the material may deform in the opposite direction after leveling. Moreover, the lengthened material arc, combined with the thickness of the material, generates a gravitational force in the rearward direction. This rearward force can cause the feeding rollers to slip during startup, leading to imprecise feeding, much to the dismay of operators.
To comprehensively address this issue, we’ve introduced a groundbreaking solution. At the feeder’s inlet, we’ve added a pair of material-feeding anti-reverse pinch rollers. These rollers are designed to rotate forward only, eliminating any backward movement. One side of these rollers features a hinged handle, which, when pressed downward during material loading, lifts the upper material-feeding anti-reverse pinch roller. This simple yet effective mechanism facilitates material insertion. During regular operation, both the upper and lower material-feeding anti-reverse pinch rollers securely grip the material, allowing it to move only in the forward direction and preventing any undesirable retraction.
With the introduction of these anti-reverse pinch rollers, the pesky rearward gravitational force of the material is neutralized, eradicating roller slippage during startup. The result is enhanced feeding precision at its core, effectively resolving the issue that has been a thorn in the side of NC servo feeder users.
In conclusion, our structural innovations for the NC servo feeder address its major shortcomings, elevating its performance and ensuring a seamless stamping process. By providing a flexible power transmission mechanism and introducing material-feeding anti-reverse pinch rollers, we have not only enhanced precision but also improved the overall user experience. These advancements are set to make a significant impact in the world of precision manufacturing, aligning with the ever-increasing demand for flawless production processes.
