High Engineering Standards

Machine Frame

The design of the machine frame is a critical part of any machine with relation to its ability to produce accurate parts for a long period of time.

Durma uses several different types of construction, depending on the certain dimension, such as length, tonnage, stroke, daylight and throat/depth. Box frame construction is standard on machines 1,100-ton and larger. For details on Durma’s unique box frame construction, please reference the ADSL series.

Precision Machining

Modern machining centers are utilized for accuracy, rigidity and smooth operation. Frames, assembly surfaces and connection holes are machined after the welding process, up to 60’ in a single pass. Surface machining nearly to grinding tolerance: 1.6-3.2 micron roughness average (0.8 micron on grinding). Parallel and square surfaces with 0.05-0.1 mm tolerances. There is no axial eccentricity. In comparison, non-precision machining results in:

• Difference between Y1 Y2 (ram level) axes• Difficult to hold tools parallel• Difficult to hold tool dimensional tolerances• High vibration during the bending process

High Engineering Standards

Cylinder Connection

In order to allow tilting of the ram without damage, special spherical seating and connections are used. This type of connection also allows sudden forces to be absorbed gently.

Ergonomic Working Height

Lower beam (bed) height for most machines is optimized at approximately 35-36” (excluding die holders and dies) for ergonomic operation.

High Engineering Standards

Lower Deflection & Longer Lifetime

Durma’s high engineering standards minimize stress and deflection. All mainframe components (side frames, ram, bed) are designed with built-in safety factors. All Durma machines are constructed from st44-2 steel. Acceptable industry stress standards for material is 8.5kg/mm2 stress. All Durma machines must meet a value of 5-6kg/mm2. These strict standards reduce deflection and increase frame durability and the ability to hold tolerances over long periods of heavy use. All incoming plate must be certified by the Durma standards and requirements. Durma’s high frame rigidity and robustness provides long-term accurate bending.

What happens if lower engineering criteria are accepted?For example, in the case of 8.5kg/mm2:

• Weight of machine can be reduced by as much as 30%• Machine operates at limit for deflection and stress• Steel fatigues from high deformation and stress at limit, as well as

the risk of cracking is present• High deflections on the ram and the bed that are too large to offset

with crowning devices

High Engineering Standards

Frame Welding

Welding methods are selected after “welding equivalent” calculation.

• MIG MAG welding on frame (below right)• SAW (submerged arc welding – below left) at cylinder connection

point. Welding at critical areas is subjected to high forces and vibration, and has to be clear of atmospheric contamination during the welding process.

• Applied force at the welding position yields rigidity and strength.

High Engineering Standards

Large Part Clearance

A combination of the specially-designed reservoir, outboard mounted ram guides, large side frame gaps, strokes and daylights provide for increased openings and reduced collisions during the bending process.

Control

Delem DA 66TThe new generation DQ Touch control offers an even higher grade of efficiency in programming, operation and control of today’s press brakes. Ease of use combined with state-of-the-art technology go hand-in-hand, improving productivity.

The touch screen gives access to the proven Delem user interface and enables direct navigation between programming and production. Functions are directly located where you need them, offering optimized ergonomics throughout the application.

The DA-66T offers 2D programming that includes automatic bend sequence calculation and collision detection. Full 3D machine set-up with multiple tool stations give true feedback on the product feasibility and handling.

Highly effective control algorithms optimize the machine cycle and minimize set-up time. This makes using press brakes easier, more efficient and more versatile than ever.

The OEM panel located above the screen, reserved for machine functions and OEM application switches, is integrated in the design and can be used depending on the required application.

• Part nesting for optimal material utilization• Advanced programming features such as common line cutting for

increased machine productivity• Direct 3-D CAD interface to streamline geometry importation

• Offline Press Brake Programming• Automatic generation bending sequence• Real time collision detection• Simulation of the bending process

Features

Y1, Y2 Precision & FlexibilityIn the ADS Series, Y1, Y2 ram positioning system, each cylinder operates independently in a closed loop system. Linear encoders combined with precision hydraulic valves and the CNC command center provide +/- 0.0004” accuracy and the ability to program all ram position, speeds and ram tilt. Application advantages include:

• Stage or progressive bending• Fade out or conical work• Enhanced material handling with total ram control

Quick-Set Front Sheet SupportsRugged support arms with disappearing stops are mounted on a linear guide rail system. This allows “fingertip” lateral adjustment as required by the bend length of the part. They are also equipped with side gauges for the fast, easy and accurate feeding of parts: small or large.

Features

Oversized Ram GuidesLong, rectangular shaped guides assure stable, smooth and secure ram positioning. Conventional machines typically have these guides mounted on the inside of the frames, resulting in obstructions to the full length acute angle bends.

Large Stroke, Daylight & ThroatThe large frame dimensions allow versatile production of parts requiring increased clearance profitably and easily.

• Forming of deep sectioned four-sided boxes• Forming and removal of complex large parts

Features

X/R Style Back GaugeWith the X/R style back gauge, the height of the back gauge is programmable in addition to the depth. This is very useful for changes in die height, extreme crowning settings, and for gauging to the flange that may be a different height than the die.

Shimless BendingIndependent left and right axes (Y1 Y2) are controlled by electronic servo valves and electronic linear position controllers. A CNC-controlled motorized crowning system homogenizes bending, forcing every point of the bending part to acquire straight bends. The need for shimming is eliminated.

Features

Pocket-Style Back Gauge FingersWhen equipped with an optional tapering style back gauge, it is necessary to have fingertips that can properly receive and secure the part when it is introduced at an angle in the X axis.

3 Step Back Gauge FingersThree step style fingers are used for the X/R and X/R/Z1,Z2 back gauge configurations. Special fingers are also available upon request.

Optional Features

Z1, Z2 Independent Finger WidthIndependent finger width movements allow gauging of stage or progressive work along the bed and also automatically set according to bend length or part width.

X1, X2 Independent Finger WidthAllows gauging of parts requiring a large taper. Fingers are mounted on a common gauge bar.

Optional Features

X PrimeIndependent +/- 5” of one finger. An inexpensive solution for tapered parts.

Six Axis Back GaugeIn this configuration (X1/X2 / Z1/Z2 / R1/R2) it can be almost assured the operator will never spend time in the manual adjustment or setup, regardless of part complexity.

Optional Features

Laser-Style Angle Measurement SystemManufacturing sheet metal parts with properly bending angles that are kept constant at all times often meets a problem during the actual production process: different parameters in material thickness and stresses. The best solution is a laser-based bending angle measuring device.

• Any bending angle can be measured• Very compact: everything in the appliance• Light influence: light or dark material surfaces play practically no

part

Optional Features

Pneumatic Die Positioning (I Axis)Two position system allows front to back shuttle from one die position to another. This can be useful in hemming and other special demanding operations.

CNC Controlled Multi-Vee PositioningCNC-controlled front to back positioning of the Durma multi-vee die. Multiple vee openings may be placed on a single side of the die block, in this case it is possible to program which of the dies you wish to use.

Optional Features

Laser Beam Safeguarding DeviceDue to the multiple purpose use of press brakes, point of operation guarding is the responsibility of the machine buyer/user. For this reason we offer the Akas ram-mounted “laser” style point of operation guard. The system is based off the location of the punch tip. Simply by pressing a button, the system travels down and finds the safe setting relevant to the punch being use at the time.

CNC-Controlled Sheet FollowersReduces operator involvement and “dishing” of large sheets or panels. Followers support large sheets as they are being bent. A ‘parking station’ is available on one end of the bed allowing the operator to quickly and easily position the sheet follower units out of the way, on jobs for which they are not required. The following units adjust easily in height and width via linear guide. Pneumatic height adjustment is available optionally (shown with three).
