W11S Plate Rolling Machine,Hydraulic Rolling Machine

W11S Series

3-Roller Plate Bending Machine

Product Description

The DURMAPRESS ®W11S 3 roll bending machines are driven by three hydraulic motors, assembled directly on the rollers with planetary gearboxes, for maximum performance with minimum effort. Our three roll plates are easy-to-use and have a high working speed. The three motorized rolls with hydraulic clamping of the metal sheet guarantee a constant and accurate treatment. It is also possible to roll a conical shape.W11S plate rolls are the easiest to use, most responsive and fastest roll plates available today. These plate bending machines benefit from excellent price / performance ratio.W11S hydraulic rolling machines are available in many models according to your needs. It is possible to roll metal sheet length from 4 to 12 feet for standard rolls. The most popular models are used to roll steel sheet thicknesses from 1/4 inch to 1/2 inch, but some models can roll steel sheet thicknesses from 1/32” to 11 1/2”. Other custom length and power are also possible.

Working Principle

Standard Components:

Standard Component

• Solid rolls made by 42CrMo
• PLC control
• Siemens electric parts
• Movable control panel
• Remote control

Optional Component

• Machine cover
• Cone bending device
• Top support rack for big diameter
• Lateral support rack for big diameter

Features

• Cone bending device contributes to make conical bend easily.

• Abundant shape bend like shape O,U,R etc.
• Specific bending process includes special bending craft,high-accuracy prebending of the edge,simple digital control.
• It’s easy and convenient to move the workplace when equipped with simple ground foundation and whole solid chassis.
• Customers can choose economic digital display type or TNC digital control type which’s totally dependent on their needs.
• The top roller is designed as drum shape.In order to make a perfect cylinder from thin plate to thick plate,support roller is always installed at the lower part of bottom roller.

Release Device

Hydraulic drop-end for easy removal offinished ferrule.

Cone Bending Device

HMl (human machine interface), intelligentoperation. Self-compensating, single operate,high efficiency, safe and convenient.
Many models for choice, economic numericalcontrol model.
APLC control system ensure the machine' sbottom and lateral rolls operate synchronously.Up to eight steps can be programmed with thetouchscreen.

Advantages:
3 rolls hydraulic plate bending machine with double pre-bending.The useful length of this machine is from 1000mm to 10000mm.The range of thickness is from 2 to 200mm.

Advantages are various :

1.Pre- rolling is highly reduced because the material gets pinched by in between the two central rolls.
2. Working can be made in one only pass, following the steps here below:
• Squaring
• Pre- rolling rolling
• Closing pre- rolling
3.The plate is fed into the machine horizontally thanks to the support of the lower roll (B) with the side roll (D).
4.The plate is squared thanks to the position that the side roll (C) takes.
5.The space to the limit of the machine reduces to one side only, thanks to the possibility of squaring and rolling in one only step.

Support Rack(Optional)

A four-roll oling machine is mainly composed of these parts: hydraulic positioning cylinder,control panel, top roll, side roll bottom rol.machine frame.

The four-roller rolling machine is suitable for the rolling forming work of sheet metal lt can roll round,curved and tapered woripieces within acertain range, and has the function of pre- rolling at the end of the sheet. The remaining straight edges are small and the work eficiency ishigh.The metal sheet can be roughly leveled on the machine.
