Decoiler is a device designed for feeding a steel strip (processed material) into a profile bending machine. The device is equipped with an electric drive of mandrel rotation (controlled by frequency converter) with automatic adjustment of rotation speed (depending on the size of compensation loop). On the frame of the decoiler there are 2 stands with rollers (drive) are installed; the mandrel with a set steel strip roll (processed material) is mounted by means of lifting devices on the decoiler stands from above, while the rollers of the mandrel are aligned with the rollers (drive) on the decoiler stands.
The decoiler of coiled metal feeds the strip into the mill through a compensating loop. Based on the loop size, the optimal mandrel rotation speed (sliver unwinding speed) is automatically set and maintained. All electric equipment of the decoiler is installed in a special compartment of the frame.
Decoiler is a device which is used to cooperate with other machines, such as metal slitting machines, metal cross cutting machines (guillotines), three rollers, manual sheet benders, rolling machines, etc. Decoiler is mainly necessary for preparatory work, when you want to cut the metal from coils of a certain tonnage. It’s no secret that one of the main price constituents of the finished product is the cost of the material from which the product. Therefore, manufacturers of a variety of products from sheet metal, sooner or later are faced with the fact that it is no longer profitable to buy a pre-cut someone else for your tasks, but economically more appropriate to purchase coils of metal a great tonnage and preparatory work to perform themselves.
This will reduce the cost of the final product and allow it to be more responsive to the customer’s needs. To simplify this operation is a special coiled metal coiler. With it our customers can have in stock a wide range of necessary coils and install them on the machine to make the dissolution of the metal strip on the strips, sheets or strips required sizes.
Sequence of the decoiler
- To install a metal coil on the decoiler, you need to remove the bobbin from the machine with a hoist (a crane or forklift), and pass it through the metal coil you are going to work with. After that, the bobbin together with the bobbin is placed back on the machine.
- To adjust the internal size of the bobbin, the machine has special adjustment screws. Optionally, there is an adjustment mechanism on the machine that allows you to adjust the inner diameter of the bale with the rotation of a single screw.
- The handwheel allows the machine’s bobbin to rotate and stop.
- A foot brake is optionally available to secure the bobbin on the decoiler.
Metal bending is a type of processing, when a workpiece is given the shape that is required for certain works. The product obtained as a result of bending, its properties are much stronger and more reliable than the same product obtained by welding. The fact is that the most vulnerable point of welded products are joints. It is there in the first place the process of corrosion begins. Products that were made by bending, have no seams, and hence will not corrode.
Bending equipment for sheet metal is called plate benders, bending machines and press brakes. You can buy automatic folding machine and other equipment on a specialized site. So you get all the necessary machines at an affordable price and solve important problems. Modern websites will help you find everything you need and get exactly the result you need. So you need to use such sites when you have such a need.
