The 4 roll plate rolling machine is the easiest one, thanks to a frame designed to satisfy every kind of needs. Advantages are various :
1. Pre- rolling is highly reduced because the material gets pinched by in between the two central rolls.
2. Working can be made in one only pass, following the steps here below:
Squaring
Pre- rolling
rolling
Closing pre- rolling
3. The plate is fed into the machine horizontally thanks to the support of the lower roll (B) with the side roll (D).
4. The plate is squared thanks to the position that the side roll (C) takes.
5. The space to the limit of the machine reduces to one side only, thanks to the possibility of squaring and rolling in one only step.
Ensure the machine is properly assembled and calibrated. Check the hydraulic or mechanical systems, safety mechanisms, and roll alignments.
Clean the metal plate and make sure it is properly sized and positioned for bending.
Adjust the positions of the bottom and top rolls based on the desired bend radius and curvature. Consult the machine's manual or guidelines for specific adjustments.
Insert the plate into the machine's entry gap, ensuring it is centered and aligned.
Engage the hydraulic or mechanical systems to start the bending process. Monitor the progress and make adjustments to roll positions as needed.
Perform multiple passes if necessary, adjusting the rolls' positions between passes to achieve the desired shape gradually.
Once the plate has been bent to the desired shape, allow it to exit the machine. Carefully remove the bent plate and inspect it for quality.
After the bending process, perform routine maintenance on the machine, including cleaning, lubricating moving parts, and addressing any wear or damage.
