W11X 3 Roller Bending Machine

Description:

The w11x 3 roller bending machine has a pre-bending function at the end of the sheet, which can feed the sheet metal at a time, and can complete the sheet end pre-bending and the roll forming of the workpiece without turning the head. The three work rolls are the main driving rolls. The lifting of the upper roller and the horizontal movement of the two lower rollers are all hydraulically driven. The lifting displacement is automatically leveled by computer control, and the screen display synchronization accuracy is ±0.2mm.

W11X Lower Roller Horizontal Adjusted 3 Roller Bending Machine

The w11x 3 roller bending machine can be pre-bent and calibrated. The chassis is heavy and the center of gravity is low. The equipment is stable. The three-roller is fully driven and the three rollers are bearings, which are fully powered and do not slip. The center distance is adjustable, and it can be adjusted when rolling thin plates and thick plates, and the center is adjustable from a single side adjustable roll cone.

Feature:

w11x 3 roller bending machine can pre-bend the ends of plate and then roll it to specified shape with one time loading without reversing it.

W11X Lower Roller Horizontal Adjusted 3 Roller Bending Machine

The 3 rolls on machine are all driving rolls and upper roll and both lower rolls can be hydraulically driven for moving vertically and horizontally respectively.

The vertical movement is controlled by computer and displayed on screen with automatic leveling and synchronization accuracy of ±0.2mm.

The tilting and resetting of bearing body are hydraulically realized.

A balancing mechanism is arranged at tail of upper roll for easily discharging the rolled workpieces and cylindrical parts.It is suitable for steel plate and galvanized sheet.

It can bend sheets with a thickness of 1mm-200mm and a width of 8000mm.

Main drive

Cylindrical gear decelerator is used in this machine. This kind of gear is formed 

through carburizing and quenching of high-tensile low-carbon alloyed steel, 

the hardness of surface of gear can achieve HRC58-62, it is of high-precision, 

high contact, high transmission efficiency, high bearing capacity, stable performance, 

small volume and long service life as well as easy-maintenance and easy-installation.

we offer two kinds of technical support and services: one is that we show 

how to operate the machine at our factory; another is that we 

sent our technicians to the customer’s factory to make re-installation and 

debugging, but the customer should pay our technicians 

for their flight tickets fee (go and back), room and board fee 

and abroad and home travel cost, besides, the customer need pay our 

engineer some fee ($50-$100 each day) for installation and training.

22

Maintenance period

Warranty time: one year(it will be counted from the day that customer 

receive the machine and finish the installation and debugging)

23

package

We always use the shrink film to wrap up the electric system, hydraulic system 

and some naked steel parts (without painting ) to protect these parts from air

corrosion or use paper wrap these part first and then brush oil to protect them.

24

Painting

We paint the machine according to the customer’s request

This machine is of stable structure, reliable performance, so it is the most optimal type for heavy-duty equipment.

The top roller can make the vertical movement, while the lower rollers make horizontal movement. Compared with top roller all directional adjustable type, it more stable, and it has low fray when slipping, high synchronous precision and few trouble.

The pre-bending is achieved through movement of lower roller bearing seat to make the top roller and lower roller in the asymmetrical position. When rolling, the hydraulic motor or decelerator and universal joint drive two lower rollers rotated.
