  • These Plate Bending Machines have four rolls and liner guidance for the side rolls.

  • The Top roll remains fixed, the bottom roll moves vertically, and the two side rolls move in liner guide way to form the shell.

  • The top and bottom rolls are power driven by planetary gearboxes with hydraulic motors.

  • Thin Plates need closely spaced rolls to avoid driving slippage.

  • Location of the bottom roll directly below the top roll ensures very good grip on such jobs.

  • Due to the high productivity of low thickness shells, the four roll machines prove to be an attractive investment for mass production of pipes and shells.

  • Over and above the cones, other non-circular shapes like oil tankers & elliptical shells can be made.

  • This type of roll configuration also facilitates CNC operation.

  • 20-30% higher Investment for the same thickness capacity and span compared to similar three roll machine.

Himalaya’s Four Roll Machines deliver par performance and flexibility. They are also extremely durable and accurate, and are therefore ideal for medium-to-heavy duty rolling.

Build Quality & Benefits

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. The roll guideways are machined together utilizing a fixed single reference point which allows for parallelism of all axes and precise surfaces, as well as longevity and precision of the critical characteristics of the machine.

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
Crowning1_edited.png
Crowning2_edited.png
Crowning3_edited.png

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.

Hydraulic Gear System
hydraulic gear system_edited.png

Additional energy saving is ensured in our Four Roll machines by a hydraulic system which can work at less than full capacity when jobs less than maximum thickness are rolled.

Himalaya Planetary driving system ™ used in our machines is efficient and eliminates energy wastage associated with heavy-transmission systems and yet achieves the goal of speed reduction by increasing the stages in gears and pinions. 
 

 
 

Operational Benefits

Pre-Pinching  (Pre-Bending)

Edge bending can be done before or after shell rolling depending on operator skill and choice. Thin plates can be rolled and edge-bent in a single pass.

cone.jpg
Easy Cone Bending

The cone bending process with the K series is simple. The bottom rolls need to be inclined to achieve cone bending geometry. This is controlled and monitored by electronic microprocessor (on some models). 

Our control system also ensures easy and accurate return to parallel setting after cone bending resulting into precision on repetitive jobs.

productivity.png
High Productivity
  • State-of-the-art in forming cylinders and cones.

  • Easy to install, extremely user-friendly and convenient to service. 

  • Simple to learn and operate. No extensive operator training required.

  • Robust construction reduces wear & tear.

  • Readily available spare parts.

  • Tropicalized oil cooling system ensures non-stop operations in hot working conditions.

  • Easy to understand hydraulic and electrical system reduce unwanted down time.

versatility.png
Versatility

Other than cylinders and cones, other non-circular shapes like oil tankers and elliptical shells can be made using a PLC version. 

economy.png
Economy
  • Due to the exceptional build quality, failure-resistant linear guideway design, high operational precision, and a wide range of jobs that can accurately rolled, the F series machines prove to be the most attractive investment for any type of industry, regular production or a job shop.

  • Due to a variety of accessories that are available to enhance the machine capability, the investment is justified in more than one way. The energy saving features and negligible maintenance cost also promise a low running cost.

FAQs

What is the arrangement provided for balancing of top roll when swing arm is opened?


Top roll is counter balanced automatically once the drop end is opened without any jacks or manual arrangement.




What is done to compensate for deflection of rolls during pre-bending and rolling?


All three rolls are crowned (cambering) for compensating deflection.




Is there any method to know the position of bottom rolls?


DRO (Digital Readout) is housed on the operating console which gives the position of the bottom rolls with respect to the top roll.




What is the capacity for cone bending?


Cones can be bent up to the edge-bending capacity of the machine. The bottom rolls can be inclined for the required cone angle.




What is the level of protection for electrical components?


Some of the electrical bough outs are IP 55 like motors, switchgears etc. The electrical cabinet will be manufactured as per our standard practices and will meet IP 55 protection.




Is the main drive reversible?


Forward and reverse to the main drive is provided. The bottom rolls can be moved up and down individually.




What is the type of oil required?


Hydraulic oil – Enklo 68 Planetary Gear box – EP 90




Where are the main machine controls?


Operating console houses push buttons for all the operations of the machine. The console is movable so that the operator can keep it at any desired location.




Can we bend hot plates on the machine to get higher thickness capacity?


Although the standard machine is not meant for hot rolling, occasional hot rolling can be done (a few jobs per month) provided that suitable precautions are taken.




Some plates have high yield point. The machines are rated for 26kg/mm2. How to find the equivalent thickness?


A. Divide the Actual YP by 26. Find square root of this number. Multiply this value by actual plate thickness to get effective thickness.
