Six Types of Steel Plate Rolling Machines

What is a Steel Plate Rolling Machine? The Plate Rolling Machine (also named Plate Roller, Plate Bending Machine, Plate Bending Rolling Machine, Bending Roll Machine, and Bending Rolls) is a device for the radial forming of flat sheets. The Hydraulic/Mechanical Plate Rolling Machine works similarly to a Profile Bending Machine. However, its design is much simpler.
The Plate Rolling Capacity of CNC, PLC Steel Plate Rolling Machine:: Bending thickness from 5.00mm to 350.00mm, plate rolling width from 1,000.00mm up to 10,000.00mm.

Six Types of Steel Plate Rolling Machines

Plate Bending Machines are available in a wide range. The smallest devices are table machines with manual operation by a hand crank. The largest Plate Rollers are found in shipyards and can bend sheets several centimeters thick, for example for ship armor.

There are 6 types of plate rolling machines currently on the market. Their roll bending work principle is the same, but the structure is different. Of course, the manufacturing cost, efficiency, and precision will definitely be different:

  • Type 1: Initial pinch bending rolls
  • Type 2: Double pinch bending rolls
  • Type 3: Pyramid bending rolls
  • Type 4: Top roll variable geometry bending rolls
  • Type 5: Variable geometry bending rolls
  • Type 6: 4-roll plate bending machine

Benefits and Applications

  1. The initial pinch bending rolls belong to the asymmetric plate rolling machine, which can be pre-bent at one end, which means that the other side needs to be removed for work pre-bending, and the work efficiency is not as good as that of the double pinch bending rolls.
  2. Double pinch bending rolls can be a 3-roll or 4-roll plate roll available in light to very heavy capacities. Double pinch bending rolls can prebend both plate ends without removing the workpiece thus increasing work efficiency. Four-roll plate rolls generally are the only equipment with CNCs.
  3. The pyramid bending rolls are rarely used in cutting-edge facilities. No pre-bending capability, which means long unbend flats and not as user-friendly as other types of plate rolling machines. The very low investment cost is their only advantage.
  4. Variable geometry and PRT top roll horizontal and vertical movement 3-roll plate rolls are built to handle medium to extremely heavy plate rolling applications. Easy-to-remove end yokes can make material removal a quick process.
    A machine of this type works well over a wide range of material thicknesses.
    The lower roll horizontal movement (PRV 3-roll variable geometry bending rolls) or top roll horizontal and vertical movement(PRT 3-roll plate rolls) increases the offset distance from the top roll and in so doing delivers a distinct mechanical advantage in bending.
