FOCUS ON FOLDING
Schröder Group managing director Franz Schröder showed its classic folding bench , the AK 2000x1.5 with digital display on the manual back gauge , at Dach + Holz recently .
At the recent Dach + Holz exhibition , it showcased its motorised folding machines and shears in addition to classic manual sheetmetal folders .
“ Just like the other MAKU motorised folding machine on display , the PowerBend Multi is also capable of conical bending . Thanks to the electronically controlled two-axis back gauge , it can be used to produce conical and form-fit plug-in profiles with precision in the tenth of a millimetre range ,” explained the manufacturer .
Another innovation of this folding machine for processing thin sheet metal of up to 2.5mm thickness is the clamping function . In combination with the option of the rotating clamping beam , it is possible to reset the clamping beam , clamp the sheet and make room for the folding beam to fold hems .
“ Our demonstration of radius bending met with great interest . The PowerBend Multi handles radius step bending , which involves pressing the sheet metal with the clamping beam against an angle formed by the bottom beam and the folding beam . This creates a slight curve . This is now repeated in fine steps as often as required . The result is a rounded sheet that shows no signs of its gradual reshaping ,” added the Schröder Group .
With the EVO DuoBend , the Schröder Group has increased the flexibility of its up-and-down technology . The new folding machine for up to 5mm thick sheets has two independently operating folding beams . This unlocks new possibilities for manufacturing large-format products with opposing bends . EVO DuoBend was presented at Blechexpo last November in Germany .
“ In special applications , the simplified handling results in enormous time savings and increased efficiency . Large trapezoidal sheets can be produced with two folding beams in one tenth of the time required with a single up-and-down folding beam ,” said the manufacturer .
The EVO DuoBend is available in working lengths of 4040mm and 3200mm . As standard , this machine is equipped with a fully automatic tool-changer on the clamping beam , which can be equipped with up to 500mm high tools . The machine is programmed with Schröder ’ s own POS 3000 control system .
Another highlight from the Group at Blechexpo last November was the MAK 4 Evolution UD , which bends 6mm thick sheets over 3200mm working lengths .
Sucorema is a Portuguese company dedicated to the manufacture of machines and systems for the sheet metal industry , under its own brand Stefa . With more than two decades of experience in designing and producing its own machines , Sucorema specialises in long folding machines , rollformers and cut-to-length / slitting lines . Its Stefa VH long folder features rounded “ C ” arms to ensure enough pressure for hemming .
Australian manufacturer , SWI Machinery , offers a range that includes Simplex & Duplex folders ; Marxman slitters ; integrated cutto-length lines ; uncoilers ; recoilers ; multistation uncoilers ; rollformers and complete customised process lines .
SWI ’ s latest model Duplex folder incorporates dozens of advances in control and mechanical design . The folder is used by roofing fabricators worldwide .
“ Our Duplex folders are built for speed and durability . When designing the Duplex , we listened to what our customers wanted from an up & down folder ,” it explained . “ Our Simplex folder is fast , simple and flexible enough to be used even by the most inexperienced operators .” n
