Technical characteristics

A) AUTOMATIC ADJUSTMENT FOR CONE Constant parallel levelingcontrol of movable rolls by MASSIVE MECHANICAL TORSION SHAFTSwithout any of the adjustments and re-balancing required by hydraulicleveling systems.

B) ALL PANETARY MOVEMENTS - Eliminating all friction common tovertical, diagonal or horizontal sliding guide systems and requiring

absolutely no adjustment.

C) PERMENENT LUBE SYSTEM - No more ordinary greasing andlubrication for all the life of the machine by specially protectedscreened and full-life pre-greased components.

D) Replacement of all low efficiency components (reduction unit, highfriction bronze bushings, mechanical drives, gears, belts joined arms,sliding guides, etc.) by new high energy efficiency drives PlanetaryGears DIRECT DRIVE COUPLED to the rolls, bearings, central multi-wayelectro/hydraulic power motor) keeping the real force available on the

plate to bend (positive power) Energy saving system conforms to the"International High Efficiency and Anti-Pollution" rules and standards.

Features

- All steel structural welded frame construction (often no foundation required)- Hydraulic drives with infinitely variable speeds automatically adjusted by progressive

controls- (hydroelectric valve machines excluded)

Plate is driven by high energy efficiency hydraulic motor/planetary drive.- eliminating secondary reduction gears, chains, synchronization devices and clutches.- Instantaneous drive stop of rolls by hydraulic over-center valves- Side-forming rolls controlled by hydraulic cylinders with infinitely variable

speed (hydroelectric valve machines excluded)- Automatically controlled side roll parallelism mechanical controlled by Torsions

Bars- Hydraulic powered drop end- Automatic balancing of top roll (to open the machine)- All rolls mounted on SPECIAL floating 2 crowns rolls bearings with automatic

self-alignment- All rolls are cambered to compensate for deflection and to increase the driving

and gripping power of the two central rolls.- Fully hydraulic powered movements- One only operator required

Material Strength

This is by far the most important consideration when selecting a set of plate rolls.

Material specifications state the minimum yield strength that the material will beproduced to,but in general there is no maximum limit, steel arriving at your works is likely to beabove the specification stated minimums.

A commonly used steel is BS EN 10025:1993 S275, this steel has a statedminimum yieldOf 275N/mm2 , yet it often arrives at works gates with yields of 360N/mm2 thisincrease in yield strength will reduce the pre bend and roll capabilities of a machineby 16%.Please look at page 2 of this quotationK factor chart shows how a change insteel yield strength will effect pre bend & roll capabilities

Closing of the longitudinal seam edge

To produce a perfect closing of the longitudinal seam, the bending rolls have to bemanufactured with a correctly calculated compensating top roll camber, specific to amaterial thickness,

At point of order, the manufacturer will require to know, at which material thicknesstop roll camber is to be calculated, this is generally the material thickness at whichmost of your production is done.

For avoidance of doubt Material rolled aboveorbelow the specified materialthickness to be used in the camber calculation, is likely to suffer from barreling or

hour glass effects, to what degree we cannot be specific.

Flat produced with pre bend

There is a theoretical possibility of achieving a flat each side of the longitudinalseam of the plate approx 1 to 2 times the material thickness. There are manyvariables that influence the ability to actually achieve this theoretical flat, theexperience of the machine operator being a factor.

Cone rolling

When cone rolling, the machines capacity is reduced to that of the pre bendcapacity.ie the thickness & the length.When you pre bend a plate with the side rolls set parallel to the top roll, the bearingloading is equal at the end of each side roll. This loading changes when you tilt theside rolls to produce the cone, the side bearings at the drop end take approx 80% -100% of the loading.

Optional Extras - not included in the machine price:

Top & side supports

As rolled material moves from pre bending, to rolling, ie the rolled material passesthrough the rolls and rises upwards,when the bending radius is pretty large thematerials own weight becomes sufficient to bend the newly formed cylinder, thisoccurs as the material approaches and passes the vertical center line of themachine.

If the materials weight is not supported in this phase of the bending, it might causethe cylinder to lose its cylindrical shape, possibly creating an irregular series ofradii, plus the added possibility of bulging or creasing as the material bounces.

A machine fitted with vertical & side support units solves this problem.

Gauging

During and after the rolling you will have the need to measure the radii, how will youdo this ?. The normal method is radii templates,do you already have these ??. Thismethod is ok for small diasthe measuring of large radii with, large templates can bedifficult , we recommend the purchase of our archmeter for larger radiimeasurements

Handling

Will this tie up your craneage, would a roller conveyor bed assist.Have you a specific plate handling system - have you plate clamps, plate magnets, apneumatic lifting device for stainless material ? We do recommend that you use aroller conveyor(s) to support the flat material in front of the machine. The length ofthis supporting conveyor as a minimum needs to be the cylinders developed length.Shorter conveyor beds cause problems with material overhang, this is a particularproblem with CNC controlled machines where the actual positioning of the materialagainst the back roll is important.

CNC Control

To have a fully automatic bending cycle, a CNC (MG Touch Command) will give youfull control of the bending operations other than controlling the whole loading anddownloading process. Our own software written by our engineers is somethingmore than the normal dedicated general software as its made for exclusively for outmachines.
