Bending 2mm Aluminium Sheet
Place the fracture line over the edge of a table and bend the overhang slightly downwards.
Bending 2mm aluminium sheet. The bending of sheet metal with a punch and an array mounted at a folder is quite natural and normal. If you re bending 0 020 thick material use a 0 020 radius. This weakens the aluminium and creates a fracture line. Magnetic sheet metal brake can bend items impossible for traditional box and pan brakes such as totally enclosed boxes triangles alternate bends on varyin.
With a 2mm line you could be out of square by 2mm or the hole you just drilled is off 2mm. The finer the marks the more accurate your bends and cuts will be. This doesn t sound like a lot but when you are drilling four holes to mate up to another piece its important. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal.
Learn how to bend sheet metal so you. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Bending is one of the most common sheet metal fabrication operations. Protocase tech tip video.
Medium strength alloy work hardens rapidly. Quick video about bend radius watch more tech tip videos bend radii minimum bend sizes. In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend. Calculate the force required to fold 800 mm from sheets of 3 mm aluminium 25 kg mm2.
Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one. Aluminium grades 5251 h22. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle. The force must exceed the material s yield strength to achieve a plastic deformation.
This is done through the application of force on a workpiece. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick.
