A plate rolling machine is a machine that will roll different kinds of

sheet metal Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Sheet metal is one of the fundamental forms used in metalworking, and it can be cut and bent into a variety of shapes. Thicknesses can vary significantly; ex ...

into a round or conical shape. It can be also called a “roll bending machine”, “ plate bending machine” or “rolling machine”. There are different kinds of technology to roll the metal plate: * Four-roller machines have a top roll, the pinching roll, and two side rolls. The flat metal plate is placed in the machine on either side and "pre-bent" on the same side. The side rolls do the work of bending. The pinching roll holds the plate. * Three-roller machines (variable pitch aka variable geometry) have one pressing top roll and two pressing side rolls. The three-roll variable pitch works by having all three rolls able to move and tilt. The top roll moves in the

. When rolling, the top roll presses the metal plate between the two side rolls. The advantage of having the variable three roll is the ability to roll many thicknesses and diameters of cylinders. For example; The side-rolls are what produce the mechanical advantage. With the side rolls all the way open, one has the maximum

mechanical advantage Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device trades off input forces against movement to obtain a desired amplification in the output force. The model for t ...

. With the side rolls all the way in, you have the least mechanical advantage. So, a machine has the capability of rolling 2-inch-thick material with the maximum mechanical advantage, but a job is only 1/2 inch thick. Reduce the mechanical advantage and one has a machine that can roll from 1/2 to 2 inches thick. Plate rollers can be powered and controlled in multiple ways. Older plate mills are driven by

will ask about the working length of the roller, the maximum thickness of the material, top roll diameter size as well as the minimum thickness of the material. Furthermore, the material yield is another critical component to disclose to machinery companies when looking for a plate roller.
