In the realm of automated heavy plate stamping, the pivotal role played by hydraulic decoilers cannot be overstated. These sophisticated machines rely on hydraulic cylinders connected to rods, which, in turn, engage wedges to tighten the inner diameter of the coil. While this method has proven effective in initiating the coil, challenges arise, especially with high-strength or easily unraveled coils. The absence of an efficient auxiliary tensioning device can lead to coil dispersion, disrupting production, causing inefficiencies, and even posing safety hazards.

Addressing High-Strength Plate Dispersion: The Innovation of Material Support Arm Mechanism

To tackle the persistent issue of high-strength plate dispersion, a groundbreaking solution has been introduced — the material support arm mechanism for hydraulic decoilers. This ingenious device incorporates material support rollers designed to counteract the outward looseness of the material during the unwinding process. Furthermore, it exerts force on the material in the direction of coil movement, streamlining the unwinding process and significantly reducing the problem of coil dispersion, especially with high-strength plates or easily unraveled coil materials.

Unveiling the Structure of Material Support Arms

The material support arms of the decoiler boast a symmetrical structure, strategically mounted on both the left and right sides in front of the coil. These arms employ material support rollers to apply force to the surface of the coil, effectively preventing material dispersion. Key components of the material support arm include the support frame, material support rollers, hydraulic motor, and material support hydraulic cylinder.

The material support cylinder propels the support frame, in turn, driving the material support rollers to secure the outer circumference of the coil. Connected to the material support rollers via gears, the hydraulic motor imparts power, facilitating the rotation of the rollers and assisting in the unwinding process. A proximity switch (or photoelectric switch) is installed at the top of the material support arm to detect and control the distance between the material support rollers and the outer circumference of the coil. The bottom surface of the material support arm features a guide rail within the base groove, accompanied by a guide plate placed in the groove. Additionally, the guide surface of the material support frame is positioned in a groove above the material support arm, featuring a guide plate pressed against by the material support pressure plate.

Seamless Operation: The Hydraulic Decoiler with Material Support Arms

In the operational sequence of the hydraulic decoiler equipped with material support arms, as the inner diameter of the coil tightens and the material pressing arm initiates the unwinding process, the material support hydraulic cylinder comes into play. This crucial component adjusts the position of the material support arms based on the width of the coil, propelling the material support rollers to secure the outer circumference of the coil. Simultaneously, the hydraulic motor imparts rotational force to the material support rollers, contributing to the smooth unwinding process. The top support of the material support rollers effectively mitigates the impact resulting from the loosening of the coil’s outer surface.

In conclusion, the integration of material support arms into hydraulic decoilers marks a significant advancement in the field of heavy plate stamping. This innovative mechanism not only addresses the challenges posed by high-strength or easily unraveled coils but also ensures a more efficient and safer production process. The symmetrical structure, coupled with the precise control offered by proximity switches, positions this technology as a game-changer, promising enhanced productivity and reliability in the realm of heavy plate stamping automation.
