How To Form Sheet Steel

As you bend a stainless steel sheet the bend area cold hardens increasing the amount of pressure required to finish the bend.

How to form sheet steel.

How can you go about shaping metal with hand tools alone. Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material. In this video i show how to make a simple metal brake with a couple. By doing so the sheet can be bent or stretched into a variety of complex shapes.

Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes countless everyday objects are fabricated from sheet metal. See all 28 photos. In both sheet metal is sunk or pressed into a die. If you want a sharp 90 bend tap along the crease with a mallet.

Finally bend the sheet up by hand to the angle desired. The sheet metal takes the form of the design cut into the die. The first 2 stages form the curves required to form the curl and the third stage closes the curl. This video shows how to create and form your own sheet metal parts with limited tooling.

To bend sheet metal in a vice start by marking a line on the metal where you want to bend it. Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered. Thicknesses can vary significantly. Follow along as i demonstrate how you can begin shaping metal with hand tools only.

Many different tools cut sheet metal and each has its own strengths and weaknesses. The edges were tuck shrunk to create the basic contour on this piece of sheet. The applied force stresses the metal beyond its yield strength causing the material to plastically deform but not to fail. If your sheet metal is long ask a friend to stabilize the part hanging out from the form blocks so it doesn t affect the bend.

Next place the wood parallel and slightly behind the bending line. To curl sheet metal on a brake press specialized tooling is required. Clamp the wood on top of the metal to the workbench. In this case the sheet of flat steel will be formed into a wheel disc.

Chromium and nickel give stainless steel its stain resistance and attribute to the hardness of the metal. This added hardness increases the amount of force needed to place a bend on a stainless steel sheet. Next put your wooden or metal form blocks in the vice and clamp your sheet of metal between the forms.
