Understanding how a plate rolling machine in Canada works helps to understand the principles of plate bending. The plate needs to be rolled to the desired thickness for a successful roll bending operation. This is done using the auxiliary cone cylinder device. In this process, the upper roll is drum-shaped and is attached to the lower roller. The cylinder is moved up and down by a hydraulic cylinder, adjusting the horizontal distance between the upper and lower work rolls.
The bending machine has side rolls independent of each other and are placed at the right and left of the bottom roll. These rolls perform the bending process. When a plate is fed into a plate roll machine, it is held securely on either side by two other rolls. The side rolls bend the metal sheet to its desired diameter. A pinching roll holds the plate to not slip during the bending process.
The plate roll must be thickened to prevent it from slipping. The lower roller should be idled in advance to avoid fracture. It is easy to break if the lower roller does not idle in advance. The “back” side roll is a special cylinder located at the far end of the feeding point. It is positioned to act as a back gauge and helps prevent the plate from slipping. The upper and the bottom rollers must be perfectly square to avoid deflection.
A three-roll round forming machine uses a combination of hydraulic pressure, mechanical force, and external force. Its independent axes allow for a perfect bend. A back-side roll, called the back-gauge, squares the plate before bending. Once the metal sheet has been squared off, the final step in the bending process is the final step. The pre-bending process can be completed immediately after the pre-bending stage.
The bottom roller is the driving part of the machine and is mounted to the cylinder. The roll is mounted to the top of the cylinder, and the bottom roll slides into it. A hydraulic cylinder works by pumping oil through the cylinder. The piston runs up and down the cylinder and bends the leading edge. Once the top roll has been bent, the plate is rolled to the desired diameter.
The main movement of a rolling plate machine is controlled by the pressure and the amount of pressure. The upper roller moves up and down to reduce the deformation of the barrel. The lower roller moves down with, the lower roller. The auxiliary supporting rollers support the lower roller, which enhances the rigidity of the cylinder.
