If you are planning to buy a plate roll machine, it is important to know what it is used for. There are many types of these machines, each with different features. Depending on the purpose, you can buy a basic or industrial-grade machine. These machines can process plates ranging from 10 mm to 125 mm. You should also know the limitations of the plate, as well as its capacity and crowning. You can also get a portable machine that can be moved around.

Limitations of plate

There are limitations to plate roller machines. They cannot roll thick steel plates, and the top roll cannot be too large. If the top roll is too large, the part will collapse, while too little tension will result in hourglass shapes. Users need to check for the roundness of the workpiece before starting the machine, and they should run several processing steps through it to optimize the quality of the part. Despite this, plate roller machines can perform a wide range of functions, and there are several ways to customize the results.

Capacity

The bending capacity of a rolling plate machine is the capacity to bend a steel plate into a specific shape. It is a process that involves pinching the material between two rolls, using one of them as the bending tool, and repeating the process on each end of the plate. This pre-bending process prevents large flattened sections at the mating ends of the cylinder. The theoretical value of the bending capacity of a rolling plate machine is shown in Table 1. In actual use, it will be larger.

Crowning

A plate roller machine is a common tool used to produce cylinders out of sheet metal. This type of machine features a patented crowning process. Crowns are small, elevated areas on the top and bottom rolls that maximize the straightness of the roll as the plate are in motion. A plate roll without a crown will have an open butt joint. Approximately 95 percent of plate roller machines have crowns. There are exceptions, however, such as older or very large plate rolls.

Adjustment options

Many different adjustments are available for a plate roller machine, and each has advantages and disadvantages. For example, the type of material, thickness, and diameter will determine which plate roll is best. Different plate roller machines have different adjustable parameters, so users should know about the differences before buying. These options can help you get the most out of your machine.
