7 Ton Hydraulic Automatic Decoiler

30 Ton Hydraulic Automatic Double Head Decoiler

Hydraulic Automatic Decoiler

The 7 Ton Hydraulic Decoiler with Loading Car is a compact, high-precision automatic uncoiling device tailored for medium and small-scale metal coil processing lines. Different from heavy-duty 30-ton double-head decoilers designed for ultra-heavy load and non-stop mass production, this 7-ton hydraulic decoiler focuses on light-load versatility, precise feeding, flexible operation and cost-saving configuration. Equipped with a dedicated hydraulic loading car, it integrates automatic coil feeding, hydraulic clamping, constant-tension unwinding and linkage speed regulation. It is perfectly adapted to thin and medium-thickness metal coils, solving the problems of bulky equipment, high energy consumption and low feeding accuracy of traditional heavy decoilers for small-batch, diversified processing scenarios, becoming the preferred supporting equipment for precision metal forming production lines.

Compact Optimized Structure for Flexible Production

Adopting a streamlined lightweight steel frame structure with integral welding and anti-rust treatment, the 7-ton hydraulic decoiler features small footprint, firm structure and no redundant mechanical components. Compared with heavy-duty decoilers, it realizes effective space saving while maintaining sufficient structural rigidity, fully meeting the 7-ton rated load working requirement. The core unwinding mandrel adopts high-precision hydraulic expansion design, with uniform expansion force and stable clamping performance, which can fit various standard and non-standard coil inner diameters.

The matched professional hydraulic loading car is a core customized configuration of this equipment. The integrated loading structure realizes automatic coil lifting, translation and positioning, replacing the traditional manual crane feeding mode. The loading car features flexible walking, accurate lifting positioning and strong adaptability, which can quickly complete coil loading and docking in a narrow workshop space. The whole set of equipment is equipped with optimized bearing and transmission components, reducing mechanical resistance while ensuring stable operation, and realizing more flexible start-stop and steering response.

Intelligent Hydraulic Drive & Constant Tension Control System

The equipment adopts a mature and stable single-circuit hydraulic drive system, covering hydraulic mandrel expansion, hydraulic loading car lifting and walking power output. The hydraulic system is equipped with a pressure stabilizing and noise reduction module, which can output stable and constant power under long-term operation, effectively avoiding pressure fluctuation caused by frequent start and stop. The adjustable hydraulic pressure design can match different coil weights and material hardness, realizing flexible clamping without damaging the inner ring of thin metal coils.

Cooperating with the miniature PLC intelligent control system, the equipment achieves fully automatic uncoiling linkage operation. It supports stepless speed regulation and real-time speed synchronization with downstream leveling, slitting, stamping and rolling equipment. Built-in tension induction sensors monitor the unwinding tension in real time, automatically adjusting the operating speed to maintain constant tension feeding. This intelligent control method completely avoids material loosening, deviation, wrinkling and stretching defects caused by unstable tension, ensuring high-precision feeding of thin plates, color-coated plates and precision alloy coils.

Core Product Advantages (Differentiated from Heavy-Duty Decoilers)

Low Energy Consumption & High Cost Performance

Targeting small and medium batch production scenarios, the 7-ton hydraulic decoiler abandons the high-power heavy-load hydraulic system of large equipment. The optimized power configuration greatly reduces idle energy consumption and operating electricity costs. With simple structure and fewer vulnerable parts, the daily maintenance cost and failure rate are far lower than heavy-duty double-head decoilers. It enables small and medium-sized processing enterprises to realize automatic uncoiling with low investment and low operating cost, with extremely high cost performance.

High Precision Feeding for Thin & Medium Plates

This equipment is specially optimized for precision processing of 0.3mm–6mm thin and medium metal plates. The constant-tension micro-control system and low-jitter transmission structure ensure ultra-stable unwinding process, effectively protecting the surface of color steel plates, stainless steel decorative plates, aluminum alloy plates and other easily scratched materials. The accurate positioning and uniform feeding speed provide reliable guarantee for subsequent high-precision slitting, punching and surface processing, greatly reducing product defective rate.

Flexible Operation & Strong Adaptability

Thanks to the compact body and flexible hydraulic loading car, the equipment is suitable for workshops with limited space and flexible production line layout. It can quickly switch processing materials and adjust operating parameters to adapt to diversified production demands of small batches and multiple specifications. The simple human-machine operation interface lowers the threshold for employee operation, realizing one-key start, automatic operation and one-key stop, effectively improving production flexibility and switching efficiency.

Labor Saving & High Safety

The fully automatic hydraulic loading and unwinding process reduces manual handling and auxiliary operation links, realizing single-person unattended operation during production. The equipment is equipped with complete safety protection devices including overload pressure relief protection, material breakage automatic stop, emergency stop protection and limit protection. It effectively avoids safety risks such as manual collision and material collapse in the production process, realizing safe and standardized production.
