Functions

VERTICAL FORCE DRIVE

Evenly distributed ultra-high pressing force is critical to clamp the sheet metal parts for challenging folding cycles such as open or closed hems. The unique design of the rigid C-frames combined with the vertically positioned clamping beam is the basis for this unique Technology not found in any other design of folders around the world. All the force is evenly distributed over the full length of the sheet being bent.

THALMANN’s Vertical Force Drive (VFD) ensures that all forces are vertically applied to the sheet metal that is being bent. This design principle of THALMANN machines guarantees that the forces applied for the bending process are efficiently used without significant losses.

Unlike other technologies in the market the vertical force is applied directly at the zone where the actual bend is being formed.

TORSION SHAFT TECHNOLOGY

The kinetic Torsion shaft technology provides maximal precision and reproducibility of folded parts. This technology is unmatched and unique to all THALMANN folders.

The synchronized distribution of force to the machine is at the heart of all THALMANN machines and can be compared to the synchronised mechanical control used in aircrafts. No other folder in the market is capable to deliver folded parts with an accuracy delivered through this technology.

MODULAR TOOL GEOMETRY

Three different tool geometries are available for the TZ model upper clamping beam.

The standard tool is a straight upper clamping beam with a very flat angle and inclination of only 35° degrees. This tool allows the manufacturing of profiles with a side ratio of 3:4, (ratio of profile height relative to depth) for instance 40 mm height and 60 mm depth as shown in the picture.

Optionally available is a curved upper-clamping beam tool, resembling a goat’s foot. This unique tool offers maximum space on the machine outside and can be used to form parts with a side ratio of just 1:2, e.g., 40 mm in height and 80 mm in depth as it is shown in the picture.

A further optional is the upper clamping beam tool with a nose. This tool geometry was especially designed for the production of typical roofer parts and points on extra space on the machine inside, e.g. as shown in the picture: 50 mm inwards and then 25 mm up).

The modular tool geometry is completed by the specially designed cropped folding beam. This is retraced by 15° degree and 15 mm offset to the bending line. The beam has a working width of 10 mm plus 10 mm auxiliary rail. All together results in significantly more free space and an increased clearance of totally 275°, providing key flexibility when folding. Architects, industrial and façade designers are continuously looking for new profile geometries. With the addition of a cropped clamping beam on a THALMANN folder a wider range of dimensions of bended sheet metal parts can be produced. With this feature THALMANN customers are able to expand their product portfolio and business for folded sheet metal parts.

BACK GAUGE STOP-FINGERS

A cropped bending beam allows more freedom and possibilities in the production of sheet metal profiles. The free space is extended through the folder cropped beam dimension. The additional space allows for bends with a 1:2 aspect ratio.

SHORT PART STOP-FINGERS

Parts that have length down to 100 mm are possible with sideways adjustable short back gauge stop fingers.

TAPERED BACK GAUGE

The production of tapered parts is possible up to dimensional offset of +/- 500 mm. The positioning of the sheet metal is fully automated and multiple sheets can be manufactured in a tapered shape at the same time on one machine.

With the option of an automated tapered back-gauge, architects, roofers and engineers have the possibility to develop novel profile geometries and extend the scope of façade design.

MATERIAL THICKNESS ADJUSTMENT

Hydraulic material thickness adjustment allows for an automatic adjustment of the air gap between the bending tool and upper clamping tool. A perfectly set air gap between the bending tool and upper clamping tool lays the foundation for a flawless bend.

Hydraulic material thickness adjustment allows for an automatic adjustment of the air gap between the bending tool and upper clamping tool in order to compensate for the differences in sheet thickness. The result is an air gap that is always optimally set, leading to a perfect bend radius.

DYNAMIC CROWNING

Uniform angles over the full length of the folded parts is guaranteed trough a dynamic automatic upper beam crowning system. This innovation ensures that the unwanted effect of overbending at the profile ends (the “banana effect”) is eliminated fully.

SAFETY CONCEPT

Laser guides around the machine guarantee a safe environment for operators to work in. The safety zone is placed as such that efficiencies and sufficient workspace during operation of the machine are maintained.

THALMANN’s safety concept is fully complient with the EU-guidelines for “Standard-Sicherheitsausrüstung” and “Sicherheit von Steuerungen”.

Hardox

To improve durability and for heavy duty bending operations, HARDOX 400 steel bending beams will greatly enhance tool life as well as maintain accuracy of folded parts. The type of steel used to produce the beams is similar to the steel used for excavator shovels.

The extremely wear resistant Hardox beams will under normal operation last the lifetime of the machine and can be welded when damaged. Hardox beams on a THALMANN machine improves the stiffness and stability of the machine.

ELECTRICAL SLITTER UNIT

Companies that apply additional cutting of folded sheets can integrate this operation on the THALMANN machine by adding a fully automated slitter unit. Investment in additional dedicated cutting or de-coiler units can often be avoided selecting this machine option.

In addition to achieving operational efficiencies trough the integration of folding and slitting in one operation, the folded metal sheets are less prone to damaging due to the reduction of manual handling. Scratches or bumps will be avoided with an electrical slitter unit.

On one and the same guiding system slitters and hemming/roll former heads are interchangeable. Both reductions in costs and investments are clear benefits and can be retrofitted on an existing THALMANN machine.

HEMMING AND ROLL FORMER UNIT

Modular and interchangeable hemming and roll forming units extend possibilities of forming sheet metals on a THALMANN machine. The hemming and roll forming unit can be mounted directly on the THALMANN long folding machine. This unit is ideal for the production of calibrated highly accurate dimension panels and very tight hems.

In addition to achieving operational efficiencies trough the integration of folding and a hemming and roll former unit in one operation, the folded metal sheets are less prone to damaging due to the reduction of manual handling. Scratches or bumps will be avoided with an electrical slitter unit.

LED BENDING LIGHTS

Safety of machine operators is significantly improved through positioning of LED lights under the upper clamping beam. Different colour settings can be selected to match the optimal light conditions.

M-GUARD REMOTE ACCESS

For an efficient and extended scope of remote service, the optional M-Guard functionality is recommended. A secure and fast direct link between a THALMANN machine anywhere in the world and the service team in Switzerland is easily established with M-Guard.

M-Guard offers the possibility to perform software updates, software diagnostics and problem solving tasks. Up- to-date VPN technology ensures safe and fast data-transfer. Remote maintenance significantly reduces costs and time as no travel will be required to deliver this service.
