Bending Aluminum Sheet Metal

As this happens you gain a small amount of total length in your part.

Bending aluminum sheet metal.

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. From a bending perspective it s always best to bend these parts in an annealed state and then temper them to the correct condition. 6061 t6 aluminum is tempered and notorious for not bending easily. If you re bending 0 020 thick material use a 0 020 radius.

For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. Determine your minimum bend by measuring the distance from your closest feature i e. Insert your aluminum sheet into the brake beneath the removable clamp bar. If you have any questions or want to discuss your design contact us.

Likewise when you are trying to develop a flat pattern you will have to make a deduction from your desired part size to get the correct flat size. In high purity forms aluminum is soft and ductile. 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. Depending on designation alloys go through different heat treatment procedures during production.

That s the ideal anyway but the reality is that many parts arrive at the press brake in a less than ideal state. Now that you know your bend allowance take your protractor and draw a clear line with your marker across the point at which you will bend your sheet metal.

Mark your bend lines. A cutout or the edge of your flange to your bend. Simple sheet metal bender using a hand roller clamps and plywood. Choose a bend radius that matches your minimum bend.

Make sure the bar is seated firmly inside the frame. This is done through the application of force on a workpiece. Then place the clamp bar back down on top of the aluminum crosswise. Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius.
