Folding machines: purpose, device. Modern folding machines are used to create blanks for various types of folds.
Folding machines will be indispensable for the arrangement of folded roofs, as well as for the manufacture of roofing accessories, which are auxiliary. This includes elements from the drainage system, end and front elements,
. and with its help you can also make a ventilation box of galvanized metal.
Folding connection is nothing more than twisting two adjacent sheets of metal to each other, and to arrange such a twist, the fold should be folded along the edge of the sheet, and a folded machine is required to create such a fold. There are two types of seam connections, namely double and single seam, and in addition they can be recumbent and standing. The choice of connection will largely depend on the tightness.
As for the recumbent joint, they are similar to the standing one, but with the difference that they are wrapped on one side. Now quite often you can find L-shaped roofing folds on sale, but there is no practical benefit from such a connection, and it cannot be called better or worse than a double bend, but most people believe that this is how the roof will look many times more spectacular. The L-shaped fold looks especially interesting on a rounded radius.
Please note that when choosing equipment, one should take into account, that is, machines in order to create recumbent folds, to create standing folds, as well as universal devices that can be rebuilt according necessary for any kind of bend.
The main advantage of seam roofing can be called the fact that the overlap is obtained without the presence of fastening or connecting holes, monolithic.
But still, the roofing metal itself is quite thin and it is extremely inconvenient, and sometimes even impossible, to make blanks in production, and then transport them to the object.
A small folding machine for roofing can radically change the situation (for the better). With the presence of such equipment, it is possible to create blanks on site, and in addition, there are even models that can be installed directly on the roof.Note one more nuance - to make bends at the edge of the sheets, a folding machine is required, and to make a double fold and crimp the connection to bring it to the final result, another machine is required, a folding machine. It helps to reduce the time for arranging the roof several times.
Most often, the thickness of metal for roofing works is 0.05-0. 1 cm, but the maximum can be 0.12 cm.But believe me, good machines for standing seam roofing are designed for working with metal, the thickness of which is from 0.
03 to 0.15 cm. Such equipment can already be considered practical professional, and on it you can make not only all kinds of roofing pictures, but also bend the workpieces under drainage or ventilation pipes, and in addition, make gutters and ridge-type linings.
Interestingly, that a blank for a folded roof (a strip of metal for a roof with folded seams) is called a "Picture" among professionals.
The principle of operation of the device is quite simple - any folding machines have a number of curly rollers for crimping, which fold the edges of the sheet.
The nip rollers should be installed in pairs on the nip shaft. For amateur use, a hand-operated machine is perfect. The number of crimping shafts can be very different, but no matter how many of them there are, they will be brought into action by the gearbox, and the gearbox itself will rotate thanks to the operation of the electric motor. Yes, as already mentioned, there is a device that operates from a manual drive, but they have low performance and such devices can be seen with our own eyes extremely rarely.
" ILMAKSAN KM 7.
1 meters, length 1 meter, width 0.6 meters.
"METAL MASTER MLC 12 DR-T"
With the help of such a device, you can perform bending of both standing and recumbent folds, and in addition to the roofing picture, you can even make pipes for the ventilation system on such a machine.
"Metal Master FDS 1250"
This device is a manual folding machine.
"MetalMaster GLF A4C"
This folding machine is considered universal.
This model of the folding machine is much smaller and lighter in weight than analogues, and this allows it to be used for work on a construction site. The package includes a roller-type stand for feeding rolled metal into a coil.
Such a stand is a way to support weight up to 1000 kg.
These are the best models of folding type machines.
More about SFP 700
When using a device of this brand, all types of roofing can be made in the form of rolls, and not separately folded sheets.
When using the SFP 700 machine, you can significantly reduce the time for performing all work several times, which will help increase labor productivity and minimize the number of transverse-type seams on the roof.
Renting a folding machine makes it possible to create double and even triple locks at the junction of the roof, and the finished panels will have rolled ribs. Such elements help to significantly increase the strength of the entire structure and improve the appearance of the roof. The use of the device will also be relevant when it is required to form a roofing picture of a trapezoidal, rectangular, wedge-shaped shape.
In addition, such handheld equipment can be used for:
A hand-held machine is used to make various profiles at the edges of a workpiece or galvanized steel sheet. You can also use materials with a paint and varnish or polymer coating.
The only and significant drawback is the high cost and dimensions of some of the models, but such a device and it are similarly different:
Not everyone can afford to buy a folding machine, so very often people try to manually assemble such a machine.
A do-it-yourself folder is unlikely to have the same functions, but it will cost you only 2,000 - 3,000 rubles.
The self-made machine is designed for use in the home workshop. Such a device is screwed to a wood workbench, but if legs are made for it with the help of welding, then such a machine can be easily carried.
The structure as a whole consists of three parts. Usually everything is welded and screwed onto the base part.
Note that the hardest part is to find perfectly flat corners. The easiest way is to give them to the milling machine, because if you do not do this, the folds will be crooked.
First, the front part of the structure should be screwed to the base angle:
For the crimping tooth, it was not in vain that the band saw blade was chosen, since it is a strong and rigid metal that is required to manufacture a folding machine.
To get a high-quality fold, two main parameters must be set:
dimensions, the seam allowance will turn out to be 2 cm, that is, on the edges from sheets that are adjacent, 1 cm should be set aside.
Principle of operation
How to use the device:
Folder work is in the video.
Now we hope that it will be easier for you to choose one of the folding machine models. As for hand-made devices with a hand-made drive, they are suitable only for amateurs, and for professional-level work it is better to buy factory machines.
