Three-Roll Plate Rolling Machine Parameters
A three-roll plate rolling machine is a metal fabricating machine that uses rolling force to shape a metal workpiece into predetermined curves and sections. A three-roll plate rolling machine is composed of three rolls, each set at a different angle and is used for rolling sheets of metal to desired shapes. Manufactured in various sizes and configurations for use in heavy duty and light duty applications, these machines are used to produce retaining rings, cones, circles, discs, and other metal shapes.
The main parameters of the three-roll plate rolling machine include the roll shaft diameter, roll face width, roll material, roll diameter and rollers force. The roll shaft diameter determines the amount of force the rollers exert onto the sheet material; the larger the diameter, the more force that is applied. The roll face width is the distance between the inboard faces of the two rollers, and affects the rolling length that can be achieved. Roll material can vary, and may be specified according to industry-standard designations, such as 1018 low-carbon steel and 1045 mild steel. The roll diameter is the inner diameter of the rollers, and may affect the size and shape of the output. Finally, the rollers force is the amount of force applied by the rollers, which can be adjusted to suit the sheet thickness and shape.
Additional parameters may also be utilized in the accuracy of the rolling process. These include the sheet feed, sheet bend angle, sheet coil height, sheet speed, and sheet force. The sheet feed is the amount of material fed into the rollers before it is rolled. Sheet bend angle is the angle that the sheet will be rolled to in a curved shape. Sheet coil height is the height of the coil, which affects the size and shape of the part. Sheet speed is the rate at which the part is rolled, and is generally expressed in terms of either feet per minute (fpm) or revolutions per minute (rpm). Sheet force is the amount of force that is applied to the sheet during the rolling process, and is typically expressed in tons.
By controlling these various parameters it is possible to achieve desired levels of quality and precision in metal pieces. Variations in parameters can also be used to replicate certain shape profiles within metal works so that they are more easily assembled. Both vertical and horizontal rollers can be found on most three-roll plate rolling machines.
In short, the three-roll plate rolling machine is an incredibly versatile metal fabricating machine. Utilizing a variety of parameters, it is possible to make metal pieces to a wide range of desired shapes, sizes, and angles. With its roller force, speed, feed, and angle control capabilities, this machine is an invaluable asset to any metal fabricator.
