Plate rolling is an essential method in the production of equipment used in home appliances and automobiles. Plate rolling enables a sheet of metal to form into round, cylindrical or conical shapes. A piece of plate is positioned in a machine and being curved between three or four rolls.
The following is the brief inquiry of the types and applications of the plate rolls:
TWIN ROLLS PLATE BENDING MACHINE
This bending machine is the best solution to roll thin plates out of minimal diameters. The upper roller of this machine is the unyielding roller, and the lower roller is the elastic one covered by excessive polyurethane material. When the roller is rotated, the feed plate and upper roller are pressed in pressure, and the flexible layer is forced to produced elastic deformation.
Advantages:
- It is possible to do high accuracy shaping in one stroke.
- Do not cause scrapes on the surface of parts.
- The metal plate will not fabricate crack while in rolling.
Disadvantage:
- The machine can’t process thick sheets of metals. The maximum thickness of the plate is 6-9mm only.
THREE ROLLS PLATE ROLLING MACHINE
There are many types of 3 rolls plate bending machine. In here includes the asymmetrical, horizontal, and geometrical three rolls plate.
A mechanical motor navigates asymmetrical three rolls. Horizontal three rolls are the most customary plate rolling machine and hydraulically driven and can roll a plate with the thickness raging 6-40mm. The geometrical rolling plate machine is the advanced apparatus at home and abroad and can move a metal plate with a range of thicknesses 20-250mm.
Advantages:
- Tested and reliable hydraulic machines.
- Guarantee an accurate and abiding drag of the material.
- Easy to use and brag a unique versatility of bent materials.
Disadvantage:
- Cannot roll multi-segment arc shape.
FOUR ROLLS PLATE ROLLING MACHINE
This is the most well-grounded rolling machine in the manufacturing industry. It was a universal machine that can roll multi-segment arc shape, square, circular, and arc. The plate, if held firmly in place between the top and bottom rolls and the side rolls, make a move vertically to construct bend.
It can be connected to the CNC system with a high standard of automation. Bending complicated shapes can be done quickly with this machine. Besides, this machine doesn’t need an operator to flip and remove.
Advantage:
- It can gratify the whole range of sheet metal rolling.
- The most accurate and fastest bends are made through four rolls plate bending machine.
Disadvantage:
- It is costly, and some claimed to be impractical.
Plate Rolling is one of the most essential yet most complicated processes in metal fabrication. Years back, the operators of these machines learned the art of plate rolling by just doing it again and again, but today, with our advanced technologies, plate rolling can be in full automation.
In fabrication, it is essential to know these types of plate rolls to be able to adopt following the need and to be able to provide the best materials for consumption.
