Four Rolls
Bending Machine

Model

MCH-4R
High Precision and Heavy-Duty Group

VB
High Precision and Very Heavy-Duty Group

Description

Using a powerful hydraulic system, the Four Rolls Hydraulic Plate Bending Machine is characterized by high security and precision in the bending process. In the clamping pressure between the lower and upper roll the bending plate is backer up constantly, especially in the rather complex pre-bending operation. The symmetrical arrangement of the side rolls makes the pre-bending possible from both sides without changing the sheet. The bending operation is made by the pitching of the side rolls to create the appropriate radius.

Three Rolls
Bending Machine

Model

MCH-3RP
High Precision and Heavy-Duty Group

SRAH
High Precision and Very Heavy-Duty Group

Description

We have now over 100 years’ experience and all our knowledge are reflected in the latest generation of Three Rolls Hydraulic Plate Bending Machines. The Three Rolls Plate Bending Machine is a more economic machine when compared with the Four Rolls Machine but is also a capable machine to cover a big part of the demanding roll bending necessities. The pre-bending operation is made by the pressure between the side and upper roll and the symmetrical arrangement of the side rolls make the pre-bending possible from both sides without changing the sheet. The bending operation is made by the pitching of the side rolls to create the appropriate radius.

Two Rolls
Bending Machine

Model

BU-U
Very High Precision and Profitability

BU-UT
Very High Precision and Profitability

BU-UA
Very High Precision and Profitability

Description

Our 2 Rolls Plate Bending Machines, model BU, gives proof for years. It combines High Precision with High Capacity and Profitability. The machine has superposed bending rolls. The top roll is made from steel, whereas the bottom roll is covered with “Urethan”. By the impress of the top roll into the flexible bottom roll (Urethan Roll), plates will be bent with high precision. A perfect pre-bending of both sides of the plates will be obtained. Using an extensive range of tools solutions, different diameters can be formed.

Automatic Ejector
Fully Automatic Roll Bending System
Special Bending Tools (Slip On Tubes, Flexroll, Special Top Roll, Device For Removable Top Roll)

Slip On Tubes

The application of slips on the top roll allows the fabrication of pipes with big diameters. Different slips available accordingly the machine model.

Flexroll

Using the Flexroll System the sheet metal is first made into cylindrical form and as secondary operation is formed in the opposite by the scraper blade. It is therefore possible by simply changing the scraper blade position to achieve any required pipe diameter.

Special Top Roll

The special roll is a special, of the whole length, supported roll with a small inner diameter. By supporting the deformation is prevented. With the special roll it is possible to bend cylinder with small diameter and with great accuracy. No standard but customer specific.

Device For Removable Top Roll

This device composed by top support of the top roll allows using different top roll diameters and lengths. The device is designed especially for the fabrication of pipes with small diameters.
