High Speed Heavy Duty Double Head Hydraulic Decoiler Machine (Max.16T) for High Speed Coil Feeding

Heavy-Duty Double Head Hydraulic Decoiler for High-Speed Production

A double head decoiler machine is an essential piece of equipment in modern metalworking and stamping lines. It is designed to improve efficiency, reduce downtime, and ensure continuous material feeding. By using two mandrels, the machine allows one coil to work while the other is prepared in advance. This setup greatly shortens coil changeover time and keeps production running smoothly.

Key Features of the Heavy-Duty Double Head Hydraulic Decoiler

1. Fast and Easy Material Loading
   The hydraulic decoiler adopts a rotary box structure and a precise brake device. This design ensures quick coil loading and stable unwinding.

2. 

   Hydraulic Expansion System
   A mandrel inside the main shaft works with an external expansion mechanism. The hydraulic station drives the mandrel and expands the support tiles outward, providing strong and reliable expansion force. When not needed, the mandrel moves in the opposite direction to release the coil.

3. Stable Brake Device
   The new brake system uses a moving ring, damping brake ring, and adjusting handwheel. By turning the handwheel, operators can adjust the friction and control the unwinding speed with accuracy. This guarantees smooth and consistent operation.

4. Improved Structural Stability
   Bearings are placed at both the upper and lower ends of the rotary box. This increases rotational stability and extends the service life of the decoiler.

Working Principle

The double head decoiler machine operates by driving one roll to unwind the metal strip while the other acts as a backup. Once the active roll is finished, the backup roll is quickly connected, minimizing downtime. As a result, workers have more time to load the next spare roll without affecting production speed.
