In the realm of stamping production lines, the journey of coiled materials begins with their placement onto the material support plate of the decoiler. From there, these coiled materials are seamlessly directed into the subsequent leveling machine or punch feeder. Both the decoiler and the leveling machine have their designated waiting areas. However, complications may arise during the uncoiling process, especially when dealing with thick materials or coils exhibiting uneven edges. Such issues can introduce variations in material tension between the decoiler and the leveling machine, leading to material unwinding. This unwelcome discrepancy not only affects the quality of uncoiling but also hampers the overall efficiency of the stamping production process.
To address these challenges effectively, the installation of a pneumatic material pressure device onto the standard decoiler becomes imperative. The decoiler pressure device comprises a support structure and a driving mechanism, featuring specialized pressure wheels. The driving mechanism’s primary function is to engage these pressure wheels and apply the necessary pressure to the material. What sets this pneumatic pressure drive device apart is its reliance on an air cylinder, securely affixed to the decoiler support structure. This cylinder is intricately connected to the pressure wheels through a dedicated transmission mechanism. Opting for an air cylinder as the driving force for the pressure-type decoiler offers distinct advantages, including pollution-free operation and reduced resistance when compared to hydraulic pressure methods.
The transmission mechanism governing the pressure arm of the decoiler consists of a pivot axis, a swing arm, and a connecting rod. The swing arm and connecting rod are firmly attached to the pivot axis, with a pressure wheel affixed to the end of the swing arm, farthest from the pivot axis. The piston rod of the cylinder is intricately linked to the connecting rod. Within the support structure, two pivot axis brackets secure the pivot axis at both ends. The swing arm and connecting rod are thoughtfully positioned between these brackets. When the piston rod of the cylinder moves, whether upward or downward, it triggers a corresponding motion in the connecting rod. Consequently, the pivot axis, coupled with the attached swing arm, sways, thereby influencing the pressure wheel’s interaction with the material support plate of the decoiler.
To facilitate precise control, the cylinder is connected to an electromagnetic valve, and the control end of this valve is seamlessly integrated with a control system that governs the valve’s opening degree. The control system’s signal input terminals are meticulously connected to both the pressure and release buttons. By simply engaging the pressure or release button, the control system promptly receives the corresponding signal, thereby dictating the electromagnetic valve’s opening degree. This ingenious setup empowers the piston rod of the cylinder to move as required, orchestrating the motion of the connecting rod and, consequently, applying or releasing pressure through the pressure wheel onto the material support plate of the decoiler. This streamlined operation of pressing and releasing the pressure wheel proves to be not only efficient but also user-friendly.
To enhance longevity and minimize material wear during the uncoiling process, all pressure wheels on the decoiler are outfitted with a flexible layer composed of soft material. This thoughtful addition serves to safeguard the material, ultimately maximizing the benefits enjoyed by customers.
Incorporating pneumatic decoiler pressure devices into your stamping production line can be a game-changer, ensuring smoother operations, improved product quality, and enhanced overall efficiency.
