Advice 1: How to bend aluminum profile

Aluminium is the easiest metal to create a variety of homemade creations, as is easy to bend and has a relatively low melting point. If you love to create something with your hands, you probably have question how to bend aluminum profile. Actually, the problem is not how to bend aluminium is not that hard to do. The real problem is to bend it smoothly, without "bunching" and cracks.
How to bend aluminum profile
You will need
  • - gas burner;
  • - sifted river sand;
  • - tube Bender;
  • - bending machine;
  • - three roller machine together ;
  • cutter or an angle grinder;
  • soap.
To bend aluminum pipe, take river fine sand (sifted is better) and calcined it; the sand must be absolutely dry. Tamp it tightly into a tube and close it from both sides of wooden studs, and the second is better a hammer to make the sand more compact. Bend the pipe - if done correctly, it will bend smoothly and without corrugations ("accordion"). In no case do not violate the listed conditions, otherwise the pipe can go on an oval or even tear along the seam.
To facilitate bending, optionally heat pipe with sand burner - then the bending can be simply hand effortlessly.
If you need to bend a large number of tubes, buy a tube Bender to the desired diameter with the help of which you will be able to bend pipe easily and quickly. To further speed up the process, you have to heat the metal.
Another option is the flexible pipe: heat pipe aluminum to become plastic, fill it with water and freeze. When the water freezes, bend the pipe.
Put in the steel spring or plastic pipe to bend smoothly.
To bend the aluminum corner, heat it with a torch and in several stages, gradually bend.
For a quality flexible corner together use the three roller machine or press his mill, where there is a Board for area.
To smoothly bend the aluminum sheet, take a cutter, for example, machined from a thin file, and marked lines make wide incisions (grooves) with a depth of at least half of the thickness of the sheet. Then carefully bend the sheet in the direction of the grooves - the line would be very smooth. Cut into the sheet with a grinder - it limit the depth of incision and along the marked line exactly penetrate the sheet.
If you want to bend small sheet (0.5 m), put in place bend the metal channel, angle or wooden Board, clamp and pull through the sheet. Very carefully with a mallet for delicate work to bend the sheet.
Sheets of large size bend with bending machines.
Useful advice
To determine whether you have enough warmed up the metal before heat, DAB it with soap. Soap gradually darkens, and when it becomes dark brown, the metal ready for bending.

Advice 2: How to bend aluminum pipe

It is often necessary to bend under a certain angle aluminum tube. And if it is important that tube left tube and retained inside diameter, problems arise. Which, however, can be resolved.
How to bend aluminum pipe
You will need
  • - pipe Bender or
  • - machine tool Volnova or
  • - a spring of appropriate diameter or
  • the small sifted sand,
  • - a blowtorch or gas burner.
First, for these purposes commercially available and implemented in the free market pipe Bender, s of various types. Benders are stationary and manual. For domestic use well suited, for example, a pipe Bender for thin walled pipes. It can be used to bend copper, aluminum, thin-wall tube with plastic coated and stainless steel pipe from diameter 10 to 25 mm.
Before you begin, install the bending desired angle of flexion.
Take the machine in hand or clamp it in a vise.
Insert the tube and begin to bring arms.
Home craftsmen have been using the machine tool Volnova, which is easy to make yourself or order an experienced master.Figure: 1 — arm, 2 — clip, 3 — movable rollers, 4 — plate, 5 — roller-pattern, 6 — clamp, 7 — tube.Insert tube between rollers so that its end entered in the collar 7. Then the handle 3, turn the bracket around a stationary roller until you get the desired curve.
Return the handle to its original position and remove pipe.Clamp to clamp the long end of the pipe, and bend a short.
If neither bending, nor of the machine tool Volnova not, you can bend aluminum pipeusing the spring, a suitable diameter.Place the spring in a pipe in place of the bend and bend, preferably on the roller. The spring will keep the pipe wall from undesirable kneading.And the spring and the tube it is desirable to warm up.The spring then get fixed for the pre-wire.
Another old tried and tested craftsmen method.Fill the pipe with dry sifted sand.Plug the ends securely, so that during operation the sand is not squeezed.Secure the pipe in a vise and heat with a blowtorch or gas burner to the future site of bend.
If the paper, approached to the place of heating, begins to char, so the sand is hot.Start bending the pipe.

Advice 3: How to bend sheet metal

With Amateur designing and building is frequently necessary to bend the sheet metal. To do this quickly and gently, without damaging the sheet, in practice it turns out not so simple.
How to bend sheet metal
If you need to bend a sheet of thin metal (e.g., tin), draw on the fold line using a ruler and a cutter, a deep scratch (groove). After that, the metal will easily bend on the drawn line, the fold will be very accurate, running strictly at right angles. The cutter is fabricated out of a piece of saw blade for metal, a length of about fifteen centimeters. One end of the wind izoljatsionnoj with a tape, the second sharpened on an electric grindstone so that the tip turned a sharp "tooth", which is cut through the metal.
To bend thick metal harder. Gently Pat on the fold line with a chisel, natuba sheet to about half its thickness. Bottom under the anvil, or any other suitable size flat and heavy piece of metal. For smooth curl you'll need a long flat surface with a clear angle, e.g., metal area, clamped in a Vice or placed at the edge of the concrete slab, stairs, etc.
Lay the sheet on the area to cut the groove came just at its edge, firmly press. Then begin to gently bend, evening bend with a hammer. The deeper cut groove, the easier it is to bend the sheet. However, carefully bend a thick and large sheet metal is quite difficult, it requires some experience. Desirable assistant, two the job done a lot easier.
If you need to bend sheet metal ring, do this by tapping the surface with a hammer. Strikes apply on lines parallel to the bend lines. The sheet will bend stronger, carefully prostukivanie edge – the bend radius should be the same in all its points. When the ends of the sheetand, zagnuvshis, will meet back to back, they can be welded, or prilepite, after which finalize the shape of the resulting ring.
