Decoiler, also know as uncoiler, coil reel. It’s a machine that widely used in the sheet metal forming industry. It uncoils the metal strip from a coil and feeds it to the next work station in the coil processing line. HE-machine provides a variety kind of uncoiling tools for different metal coil applications:

What is the critical component of the decoiler machine?
A spindle is a critical component of an uncoiler/coil reel structure. It has two functions: One is expanded to the desired size to support and hold on the metal coil. Another one is driving the steel coil to rotate. A quality uncoiler spindle should have excellent load-bearing performance and fatigue resistance.
How many expansion ways of uncoilers?
There’re three ways of expansion movement of the uncoiler spindle: manual expansion, pneumatic expansion, and hydraulic expansion.The manual expansion is suitable for light-duty metal coils; there is a removable handle on the mandrel center, rotating the handle can push the support rod for spindle expansion.
As for the hydraulic decoiler, the support rod is pushed by a hydraulic cylinder for smooth expansion, which makes it perfectly suitable for medium-duty and heavy-duty metal coils. When the uncoiler spindle is rotating, the hydraulic cylinder on the rod will rotate together. One end of the pipeline connects to the hydraulic cylinder, and the other end connects to the hydraulic station.
What’s the spindle rotating ways of uncoilers?
There’re two methods for a spindle rotating: One is a positive way, driven by the uncoiler motor. Another one is the passive way operated by the next coil processing station, such as coil straighteners or press feeders. That why we have motorized uncoilers and non-motorized uncoilers, also know as pull-off type uncoilers.
What industry applications do uncoiler have?
Depends on different industry applications, an uncoiler machine can be applied in metal stamping lines, laser cutting lines, roll forming lines or cut to length lines, etc. It’s widely used in machinery, automotive, electrical appliance, construction industries.
