Multi Fold 'E' Drive

Multi Fold 'E' Drive

For over 60 years worldwide experience in sheet metal working industry is the basis of the range Multifold bending automates.

Design and construction guarantee a reliable operation, an accurate bending result and a long life span with little maintenance.

The Multifold bending automate disposes of a high production speed combined with a large extend of flexibility and the possibility for unmanned production. The interesting investment level makes it attractive to automise your production with the Multifold.

A wellconsidered, functional design linked to standardization guarantees an efficient production. A smart system of options provides the possibility to anticipate on customer wishes at all times.

The Multifold is extremely suitable for the flexible production of steel, stainless steel and aluminium products, such as:

• Panels for storage racks
• (Electrical) cabinets
• Office furniture
• Wall panels
• Doors
• Lighting armatures
• White good equipment
• Panels for heating boilers
• Tool cabinets

The Multifold is provided with two folding beams, one for positive bendings and one for negative bendings up to a maximum of +/- 135º. Through a mechanism the upper and lower beam are positioned (patent announced), as a result of which Z-bendings will be made without turning the plate. Both beams will be driven high-dynamicly by AC-servomotors. The hold-down is CNC positioned through hydraulic cylinders, as a result of which it is also possible to flatten a 135° converted side in the shape of a folded seam. With this, there can also be given a free programmable space.

The hold-down is standard executed with a quick change device for the bending fingers. Optional it is possible to execute this clamping hydraulic. If the clamping is opened, the tools can be (dis)mounted or moved vertically. When you fill up the bending fingers lateral, you can adjust the total width of the hold-down. This also applies for the folding list.

Retractable folding list

Optional, it is possible to retract parts of the folding list automatically, so that back laying bendings or welding lips can be bend.

Manipulator (positioning system)

The sheet will be lead into the infeed table automatically or manually. Through a positioning system, the sheet will be positioned exactly and will be taken over by the sheet clamp. The positioning system consists of two length gauges (Z-axis) and a width gauge. The two length gauges will be automatically adjusted on the desired product dimension.

After positioning by the pneumatic controlled width gauge, the gauges sink under the level of the in feed table.

Manipulator (lift function)

The sheet clamp can be lifted vertical with a stroke length of 35 mm, so that sheets with a last negative setting can be executed. This lift function can also be used to lift the product over the bottom tool if for example press through or louvres are mounted in the product.

Sheet clamp

The machine is executed with a sheet clamp that clamps the product in the middle. The turntable is integrated in the sheet clamp, which rotates the product, so that all sides of a product can be bend in one cycle. High dynamic AC-Servomotors take care of the drive of the turntable and the positioning of the clamp.
