Bending 125 Aluminum Sheet
Lift the clamp bar away from the rear of the brake frame and slide the sheet in perpendicularly to the direction you want to bend it.
Bending 125 aluminum sheet. Which aluminum alloy bends the best is a a common question customers want the answer to. From a bending perspective it s always best to bend these parts in an annealed state and then temper them to the correct condition. Your 125 thickness will need a radius of 187 to 375 on the inside of the bend. Flip the sheet over and repeat.
If you search for aluminium bend radius you will find that 6061 t6 should be bent with a minimum bend radius of 1 1 2 to 3 times the sheet thickness. Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. We re having trouble bending 6061 t6 aluminum without cracking and i was wondering if you could give us a few pointers. Create a long fracture line then progressively bend the sheet from one end to to the other.
Make sure the bar is seated firmly inside the frame. Bending is a delicate and demanding process most of the time and common fabricating processes require a degree of formability that make your choice of proper alloy critical. To define the bend region and reduce the force required to bend a part out of sheet metal down to something you can handle without a brake press slots can be cut at the bending line to. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.
The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius. Place the fracture line over the edge of a table and bend the overhang slightly downwards. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. In high purity forms aluminum is soft and ductile.
6061 t6 aluminum is tempered and notorious for not bending easily. Bending is one of the most common sheet metal fabrication operations. Insert your aluminum sheet into the brake beneath the removable clamp bar. Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6.
After a few wiggles the sheet will fracture along the cut line leaving a clean break as shown in the above photos. With care and patience full size sheets of aluminium can be cut using this method. If bending along the grain you want closer to the bigger numbers and across you can bend to a smaller radius. 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.
