How To Maintain The Uncoiler

Uncoiler, also known as decoiler, material rack, loading rack, unwinder machine, etc., is an indispensable unwinding device for metal coil to be stamped processing. Like the feeder, it is also a product that must be used on the factory workshop. It is suitable for the continuous stamping processing industry of various auto parts, hardware and electronic parts. We know a lot about several decoilers, and different uncoiler machines have different characteristics.

The decoiler/uncoiler plays a vital role in the cutting production line, pressing production line and various metal production lines. In order to allow it to be used for a longer period of time, we need to pay more attention to daily maintenance. Here are some useful tips.

1. Grease the decoiler/uncoiler mandrel regularly.

2. It is best to expand the coil within the acceptable parameters.

3. Check whether the core rod of the decoiler/uncoiler is stuck or abnormal before starting up.

4. Operate the uncoiler correctly according to the instructions and safety regulations.

5. When abnormal noise is heard, stop the uncoiler immediately.

6. In the metal production line, every operator in charge of different machines must cooperate closely.

Advantages of decoiler:

The decoiler is suitable for conveying various coil materials. Thin thin metal and non-metal materials can be equipped with motor power and feeding device. The brake device is adjustable and the main shaft is reinforced, which makes the rolling of the material roll more stable and increases its carrying capacity. It can automatically produce indispensable parts with the punching machine, saving manpower, material resources, and reducing costs. The effect is very good.

Uncoiler machine can save feeding time and improve production efficiency. It can be used with the calibration machine. It can be equipped with a motor and electrical control instead of a power frame.

Safety Features

Safety is a major concern on the shop floor as coils have become larger and heavier. Uncoilers have large, fast-moving parts, so operators must be trained on how the machine works as well as its correct setup.

Coils today can range from 33 to 250 kilopounds per square inch, and the uncoiler has been adapted to meet the demands in the yield strength of the coil. Heavier coils present bigger safety challenges especially when cutting the strap. Hold-down arms and snubber rolls are included on the machine to ensure the coil unwinds only on demand. The machine also can include feed-up drives and a side shift base to help centre the coil for the next process.

As coils get heavier, it becomes much harder to expand the mandrel manually. Hydraulic expanded mandrels and rotation capabilities are commonly requested as shops move operators away from the uncoiler for safety reasons and into other areas of the shop floor. Shock absorbers can be added to minimize uncoiler rotational abuse.

Depending on the process and speed, additional safety features might be required. These features include an outward coil retainer to prevent the coil from falling down, a monitoring system for the OD and RPM of the coil, and a unique braking system like water-cooled brakes for lines running at high speeds. These are all important to help ensure that when the roll forming process stops, the uncoiler also stops.
