Plate rollers are used in the production of nearly all types of cylindrical products. Their application extends to a vast array of items including pressure vessels (Heavily used in the Oil and Gas Industries), home appliances, ships, wind power, military arsenal, aerospace, and automobile refit.
Since not all rolled metals are created equal, every project may require a specialized type of plate roll machine. Therefore, you should expect to find a vast array of plate rollers in the market. The type of equipment you choose should be based on the complexity and uniqueness of the customer’s orders. Some of the standard metal rolling machines include:
The two roll plate machines are designed to bend flat sheet metals with a width of up to 8-12” and 12 Gage thickness. This makes them ideal for batch production of thin cylindrical items used in household appliances such as filter canisters.
Three roll sheet rolling machines can be further classified into asymmetrical, horizontal lower roller move types,s and geometric variable plate rollers. Although all tools in this category operate using different principles, they are all used to bend medium to thick plates. The three-roll sheet bending machines are commonly used not only, in general, fabricating but also in chemical, boiler, shipbuilding, metal structure, petroleum, and machinery manufacturing industries.
The 4-roll plate bending machines are renowned for transforming flat sheet metal into spherical body, cone tube body or other shapes. Four roll plate bending machines are more productive, precise, safer, versatile, and easier to operate than the rest. Once the material is set and pinched the two rolls on either side of the pinched roll do all the work without having to remove the plate and rotate it for pre-bending both ends. They can roll up to 8” thick plate steel and are most likely to be outfitted with CNC controllers for variable radii applications and complex shapes such as elliptic and polycentric workpieces. Their greatest advantage is that they can be used on a wide range of sheet metals and can also accept a high degree of automation. They can also be used to roll tube segments, ovals, rounded boxes and other shapes.
