Himalaya - Model V- Series -Variable Geometry Plate Bending Machine

Himalaya Variable Geometry machines deliver performance equivalent to that obtained with the more expensive 4-roll plate bending rolls and are therefore ideal for medium-to-heavy duty rolling.

Exceptionally high rolling capacity is achieved due to variable bending span of the bottom rolls. the rolling capacity can be 15-20 % higher than linear guideway and swing-guide designs of same top roll dia. machines.

The special configuration of this design provides for the plate bending rolls to move independently by hydraulic cylinders – the top roll moves vertically; the bottom rolls move horizontally – and are rotated by integrated planetary gearboxes with hydro-motors. This allows for optimal central distance between the bottom rolls and the distance between the bending points offering immense advantages.

For thin plates, the roll span can be drastically reduced, generating excellent traction, and avoiding driving slippage and spring-back.

For thick plates, the bending span can be significantly increased thus reducing the bending load and plate deformation.

Additionally, bottom rolls can be moved independent to each other and can be placed asymmetrically to achieve high quality edge bending.

Another key benefit of horizontally moving bottom rolls is that the plates can be fed using a simple unpowered conveyor, saving costs.

Sturdy Steel Structure

Himalaya machines have a robust steel structure made from heavy metal plates. The frames are connected to each other by a strong box design chassis. The frames have interlocks & strengthening ribs.

Rolls

The rolls are the most important elements of our machines. Himalaya designs the rolls with optimal diameter and uses forged carbon steel rolls that are machined by high precision CNC lathes. Our rolls have a special spline-based design that is extremely efficient in connecting the rolls with the planetary gear system. This diminishes points of roll failure compared to welded connections provided by other manufacturers.

Crowning

Our rolls are crowned to compensate for roll deflection during the bending process. Custom crown-machined rolls for different materials or thickness can be selected when ordering.

Alongside our excellent design and build quality, we provide the following additional features and accessories upon request from our client.

Surface-Hardened Rolls
