PivaBend – Bending to Your Needs
Pivatic’s bending solutions overcome the traditional challenges and problems of part processing by eliminating separate bottlenecking process stages, material losses and surface damage. With PivaBend the parts are bent efficiently and can also be fully machined into the desired product on a single line.
Short part cycle times are achieved by simultaneously bending all sides of the workpiece. Different bending angles, both upwards and downwards, are performed by the same unit. The programming system makes flexible production possible, whether for just a single part or for batches of thousands of parts.
PivaBend integrated with PivaPunch provides even greater flexibility for maximum uninterrupted part production efficiency. See PivaSystems for further information.

The RAS DuctZipper allows you to produce the highest quality duct work faster and easier than ever before. RAS technology and engineering have taken the seaming process from the traditional three steps down to only one. Traditional methods rollform the receiver lock, than the rollform the flange, and finally connect the two and close the seam. The RAS DuctZipper does all this in one smooth and simple operation! The result is a clean joint, extremely tight ducts, and remarkably fast throughput.
With the RAS DuctZipper, operators will be quick to realize how fast and easy it is to create perfect ducts with minimal effort. Large ducts, small ducts - it doesn't matter! That's because of the exclusive RAS material handling system designed around front and rear support arms. The system supports ducts of any size and shape to a height of 700 mm. This extremely productive in-line design moves through the machine along with the duct work. After one seam is completed, the operator simply puts the duct crosswise onto the material guidance system and slides it back to the entry point. It's that simple and most often it saves a second operator! For ducts that are longer than 2 meter, the AutoPilot automatically detaches from the material handling system.

FOUR ROLL DIGITAL HYDRAULIC PLATE ROLLING MACHINE WITH DUAL PRE-BENDING, MOD. MCB (With Roll by Wire technology)
The MCB rolling machine line is the ideal machine to bend plate from 10 mm to 200 mm thicknesses with widths varying from two to up to six metres. It is accurate, user friendly and fast (plate advancement speed of six mt/min) and represents the best available on the market today. The MCB also represents advantages not available on other models. It can automatically pre-bend the leading edge leaving the shortest possible flat end. The MCB can roll the plate without removing, turning or reintroducing the plate as required by a single leading pre-bending machine used for this range of plate thicknesses. Unlike three roll models that require pre-bending on both ends, the MCB only requires that leading edge is pre-bent. Another important advantage is the possibility to make a shell in a single pass. The operator needs to identify only the lateral rolls position whereas on the three roll machine it is necessary to identify the six or nine positions to bend successfully a single shell.

- The HCU version of plate roll guarantees optimum quality of the rolled product. Thanks to the urethane roll forming design, it is possible to achieve the best tolerances and super-fast rolling times. The standard HCU machine can guarantee output levels of 180-200 pieces/hour while the special version HCU/S reaches output levels in excess of 300 pieces/hour.
- The flat ends are eliminated from the pipes rolled with the HCU machine. The dynamic pressing force, resulting from the action of the urethane roll against the top roll, permits the complete forming of the plate along its entire length.
- The high speed and one-pass rolling process of the HCU machine also eliminates the prebending - rolling - prebending procedures typical of traditional three and four rolls machines.
- Inexperienced operators can easily operate the HCU. The standard version is complete with a fully automatic rolling cell. The only need for the operator is to load the plate and offload the cylinder.
- The Precision and Reliability of the HCU series of plate roll is guaranteed by a special patented design combined with a solid oversized structure. The exclusive hydro-mechanical roll lifting system (GHS) guarantees exact bending repeatability and constant forming pressure.
- The HCU series of plate roll is surely the ideal solution for rolling medium and large batches of tubes with thickness up to 5mm and lengths up to 2 meters.

The MAV three roll machine is the most innovative ad revolutionary machine on the market. It is a rolling machine that has many advantages unavailable on any other three roll machine. The MAV with is "variable geometry" is the simplest and easiest rolling machine to use. It works as a press in the pre-bending of the plate edges and it is in fact more widely known as the Press-Roll". Reducing the distance between the lower lateral rolls it is possible to obtain an excellent flat end, in fact the length of the flat end is the shorter than any other three roll machine. If the distance between the lateral rolls is increased, this allows very thick plates to be bent, thus increasing the capability of the machine considerably.

The DP3 is the latest evolution of the traditional three roll double pinch plate bending machine. It has been designed to cover the needs of the fabrication shop: Strength, User Friendliness, and Versatility. FACCIN's experience in manufacturing heavy and super-heavy duty machines is applied to the design of the DP3 series of plate rolls.
- The DP3 series is the most precise 3 roll machine in its category. The RGS design reduces to a minimum the distance between the bending points guaranteeing higher bending accuracy.
- The MCS bearing system, incorporating 4 independent bearings for each bending roll is a standard feature of the DP3. It guarantees higher reliability (higher capacity of load absorption) and increases the range for tilting the side rolls, resulting in more versatility, when rolling cones.
- The Ultra wide roll support with lubrication circuit are mounted within linear slides to prevent wear and tear.
- Another important standard feature to increase the versatility of the machine is the roll shaft extensions to allow dies to be fitted to bend profile and pipe.
- The very high rotation power is a guarantee of the DP3's superior rolling torque and speed, available without loss of energy as all three rolls are driven independently by hydro-motors and gearboxes directly coupled to the rolls shafts.

Hydraulic 3 rolls bending machine with total pre-bending, designed to bend medium/big thickness plates. The model EMO is a machine which is different from the traditional 3 and 4 rolls models, thanks to its revolutionary geometry. In fact the side rolls can translate horizontally and indipendently from one another with variable pitch, while the top roll which is motorised translates vertically. With this geometry the machine can be used from time to time as a 4 rolls, a pyramidal or an asymmetric.
Thanks to the variable pitch we have: 1) great versatility of the machine (increasing the interaxis between the side rolls we can roll bigger thicknesses, decreasing it smaller thicknesses); 2) the plate is always horizontal during the pre-bending phase (therefore higher safety for the operator); 3) dimensions reduced without foundations till the heaviest sizes.
From 20 mm up to 250 mm,

FOUR ROLL DIGITAL HYDRAULIC PLATE ROLLING MACHINE WITH DUAL PRE-BENDING, MOD. MCA
The MCA rolling machine line is the ideal machine to bend plate up to 10 mm thick and up to four metres wide. It is accurate, user friendly and fast (plate advancement speed of six mt/min) and represents the best available on the market today. The MCA also represents the ultimate in terms of design and innovation with advantages not available on other models. The leading edge is automatically calculated (when CNC is supplied) and this results in the shortest leading edge flat end on the market. The MCA can roll the plate without removing, turning or reintroducing the plate as required by a single leading pre-bending machine used for this range of plate thicknesses. Unlike three roll models that require pre-bending on both ends, the MCA only requires that leading edge is pre-bent.

Four roll plate bending rolls are considered as the most versatile, precise and easy to use plate roll.
The rear lateral roll, opposite to the feeding side, can be used as a back gauge for immediate plate squaring, resulting in very easy plate alignment and "one man operation".
After the plate is squared, it is always securely clamped between the top and bottom central pinch rolls, therefore prebending and rolling operations are safe and precise without the risk of the plate slipping.
The pre bending operation does not require the plate to tilt below the feeding level (as with traditional 3 roll machines), therefore horizontal motori-zed roller tables can be used to further improve the Introduction of the plate between the rolls.
The cylinder can be rolled to the diameter needed, immediately after the pre bending of the leading edge. This means that the machine needs less valuable workshop space, as an area for plate feeding is on one side of the machine only. ( See diag. at top of this page.)
The bending of the trailing edge is carried out after the cylinder is rolled. Basically, cylinders can be rolled in one pass, in one direction.
Cone rolling is much easier, the side rolls are tilted to determine the cone angle and the central lower roll can also be tilted to clamp and drive the plate.
Because of the guaranteed clamping and driving of the plate during all the phases of the rolling process, The four roll machine is the only plate rolling technology that can be controlled effectively through NC and CNC systems.
The perfect machine for plate up to 6 ins thickness.

The production of elbow parts for air ducts starts with a rollforming proc-ess. This operation seams the blank and creates one part for the lock. In the second step the internal and outside elbow duct cheeks will be rounded on the requested radius.
Traditional rounding machines use one part rolls. Since the part comes with the rollformed seam, traditional rounding machines can offer only some poor and costly compromises. Setting the rolls to the seam thickness results in poor radii. Stronger settings will damage the seam and in the long term also the rolls.
The RAS VENTIrounder for the air duct production rounds sheet metal elbow cheeks with pre-formed Snap Lock or Pittsburgh seams. The result are perfect workpieces without the need of additional spacer parts.
After having moved the rounding rings along the working length and set them to the approximate blank width, you can start rounding the blank. The rings round the sheet metal without touching the seams. Therefore the seams keep their geometry during the rounding process. A gear-brake motor with variable speed can be operated from a single phase outlet.
|
|
When it comes to manufacturing of rings, ring rolling is the process of the future. A revolutionary progress which doesn't merely stop at the elimination of chips from production, but which enables new standards of quality to be achieved.
The working principle is characterized by a driven die (roll) for the outer profile and a free rotating die (mandrel) for the inner profile which is being pressed up by supporting rolls.
