Roll formers, also known as metal forming machines, fabricate long strips of metal into specific shapes. Generally, they are used to craft coiled steel for construction projects, though these machines can also be used to perform metalworking duties like material cutting and roll punching.
For the most part, roll forming machines work in a continuous cycle where the material is fed into the machine and it makes its way through stages of operation to create the final product. Basic roll formers can be separated into 4 major parts, the first of which is where the material is loaded. This material is usually fed through from a continuous coil or in sheet form. Then, there are station rollers positioned to actually shape the metal. The station rollers are the main driving force of roll former machines.
After the material has made its way through the station rollers and has been shaped accordingly it will then present at the cut off press where it will be cut to a predetermined length. Finally, the material will exit the machine onto a conveyor belt or table, so it's important your workshop has enough room to accommodate the process.
Of course, there are a range of roll formers on the market, some smaller and some more industrial sized. Just some variations of the roll forming machine includes, curving rolls, plate rolls, ring rolling machines, section rollers, slip rollers, thread rollers and corrugated curving rolls. The type of roll forming machine you choose will depend on the work you are trying to complete.
Generally, roll forming machines are ideal for creating parts uniformly and will create these parts consistently once the material thickness is set in the machine. An added benefit of modern machines is the integration of computer software which allows the machine to produce quality products at a faster pace. Some roll formers will also have the capability to punch, cut-off, emboss, weld, slit, bend, stack and bundle materials. Such technology in newer machines simplifies the operation and speeds up turn-around times.
In saying that, it's important to note that roll formers can be time consuming and tedious to set up for operation. Operators may need to ensure roll tooling and spacers are placed correctly and that there is enough clearance between rolls on both inboard and outboard sides of the stations of the machine. Once assembled, it's important operators perform test runs to ensure the material is not deformed during the machining process.
To find the right roll former machine for your needs, speak to local dealers and sellers in your area.
