Decimating the Cost of a Decoiler Machine
A decoder machine is perhaps the easiest form of metal stamping machines to operate. It’s used to create extremely thin, flat sheets of metal (listen) in a particular shape. The sheet is then laid over the workpiece with no gaps in between. The work piece thickness varies greatly between applications.
The decoder machine works in a similar fashion to the usual stamping line. However, it is done with a continuous feed mechanism. The machine uses a solenoid coil that feeds a set of needles into an electric auger that applies pressure to the metal being stamped.
When the electric force strikes the metal the thin metal strip is quickly flattened and removed. To complete the process, the stamped metal is passed through an elongated die making it even thinner than it was originally when it was first placed in the elongating die. This is what makes the decoiling die so special. The die that the machine uses can cut to a depth of up to 0.5mm and apply the coating in a very quick fashion. This ability to apply a coating quickly means that this type of machine can perform quick and reliable die changes and adjustments as well as producing a surface that is smoother than any other types of die forming equipment can produce.
Due to the fact that the metal being stamped has a low dielectric strength the machine must always be operating at full capacity in order to keep the sheet rotating at its maximum speed. This is known as coil loading capacity or LMC. Ideally you would want to have a high level of LMC and less coil stock width. However, if you are unable to achieve this you will have a lower efficiency rating for your decojouling dies and the overall production line performance will be affected.
The final factor to consider is the way the machine operates in operation. How is the feed line affected when changing the speed of the belt? Do the dies slip off the spindle because one end is too weak? What happens when the machine encounters obstacles? These are all questions that you will need to answer if you wish to purchase and operate one of the many decoiler machines available. The answers to these questions are not all that important but they can help to improve the operation and efficiency of your operation.
There are two types of coil handling machines in production today. One type of machine works by using a pressurized air clamp to place the sheet metal into place on the die. The other type uses a hydraulic cylinder and spring to place the sheet metal into place. Hydraulic cylinder and spring systems are capable of working at high speeds, but they are limited to the amount of work that they can handle at once. As a result, the hydraulic system is more expensive than the pressurized air clamp method.
