Hydraulic Decoiler Straightener

The Hydraulic Decoiler Straightener is a dual-functional integrated metal processing machine that combines automatic coil unwinding and precision strip straightening functions. It serves as the essential front-end equipment for coil cut-to-length lines, slitting lines and various metal sheet forming processes, solving the common problems of uneven coil unwinding, strip curvature, edge waves and residual stress in raw metal coils.

This integrated equipment consists of a hydraulic coil decoiling mechanism and a multi-roller straightening unit. Adopting full hydraulic driving design, the decoiler provides stable and adjustable tension control, enabling smooth and uniform unwinding of heavy steel coils without slipping, deviation or material jamming. It is compatible with heavy-load coil loading, effectively improving feeding stability for subsequent processing procedures.

Built with a high-precision multi-roller straightening system, the machine performs continuous alternating elastic-plastic bending on the uncoiled metal strip. It thoroughly eliminates coil camber, middle buckles and edge waviness caused by hot rolling, cold rolling and coiling processes. Different from ordinary single-function machines, the synchronous working of decoiling and straightening avoids secondary deformation of the strip, ensuring consistent flatness and structural stability of the entire material strip.

Equipped with advanced PLC and touch screen intelligent control system, the equipment supports one-click parameter setting for different materials, thicknesses and widths. It can automatically adjust hydraulic tension and straightening roller gap, realizing fully automated operation with minimal manual intervention. The precision straightening effect effectively prevents sheet rebound and warping in subsequent cutting, welding and stamping processes.

Widely applicable to carbon steel, galvanized steel, stainless steel, aluminum alloy and other metal coils, this hydraulic decoiler straightener features a rigid welded frame, wear-resistant alloy straightening rollers and centralized lubrication system. It boasts stable operation, low failure rate and long service life, perfectly matching medium and high-speed metal coil production lines, and is widely used in steel service centers, steel structure manufacturing, container and hardware processing industries.
