Unraveling the Innovation: Hydraulic Decoiler’s Dovetail-Sliding Block Structure

In the realm of efficient coil handling, the hydraulic decoiler takes center stage with its cutting-edge dovetail-sliding block structure. Let’s delve into the intricacies of this innovative mechanism that not only streamlines loading and unloading operations but also ensures a secure connection between coil rolls and the decoiler’s rotating components.

The Dovetail Dance: Sliding Blocks in Harmony

The hydraulic decoiler employs a meticulous dovetail-sliding block structure that secures both the hydraulic cylinder and the decoiler spindle with robust bolts. A central through-hole in the spindle provides unrestricted movement for the pull rod within, creating a seamless synergy between the hydraulic cylinder and the decoiler spindle.

Connecting the Dots: Precision in Motion

The piston rod of the hydraulic cylinder ingeniously connects to the pull rod through a connecting sleeve. Fastened by a circular nut, the pull rod and the tensioning sliding seat find cohesion. The connecting screw thread, engaging with the movable inclined sliding block, secures itself with a nut to the tensioning sliding seat. Sleeves play a pivotal role in maintaining precise distances between the tensioning sliding seat and the movable inclined sliding block, as well as between the movable inclined sliding blocks.

Grooving Towards Efficiency: Inclined Sliding Blocks

The movable inclined sliding block and the fixed inclined sliding block, interlocked through dovetail grooves, glide smoothly along the inclined surface. Bolted onto the material-supporting tile board, the fixed inclined sliding blocks remain immobile with the assistance of circular nuts.

Adapting to Diversity: Adjustable Inner Diameter

To accommodate varying inner diameters of coil rolls, the hydraulic decoiler boasts an adjustable inner diameter within the range of ф450-530mm. When dealing with a coil roll inner hole of ф530mm, Type A iron is bolted onto the material-supporting tile board.

Dynamic Interaction: Expanding and Contracting

As the movable inclined sliding block and the fixed inclined sliding block move axially, they drive the fixed inclined sliding blocks to move parallel to the spindle. This action causes the material-supporting tile board to expand or contract along the elongated hole in the circular plate, simultaneously affecting the fixed inclined sliding blocks on the four faces.

Seamless Coil Mounting: Precision Control

Mounting a coil roll becomes a streamlined process as the hydraulic cylinder, guided by the electromagnetic valve, moves the piston rod. This movement drives the movable inclined sliding block to contract or expand the material-supporting tile board, adjusting its outer diameter accordingly. The material-supporting tile board, in turn, snugly fits within the inner hole of the coil roll, securing it in place.

Innovative Decoiler Dynamics: Coaxial Rotation Assurance

The hydraulic decoiler’s dovetail-sliding block hydraulic expansion-contraction structure, powered by a hydraulic cylinder, orchestrates the radial movement of the coil drum’s tile. This ingenious design not only facilitates swift installation and disassembly of coil rolls but also ensures a secure connection, allowing for the smooth coaxial rotation of coil rolls with the decoiler’s rotating components.

In conclusion, the hydraulic decoiler emerges as a game-changer in the world of coil handling, combining precision, adaptability, and efficiency in a seamless dance of sliding blocks and hydraulic control.
