Bend Radius For 2mm Sheet Metal

There are a two major factors that affect how tight you can make the internal radius of a bend in a piece of sheet metal.

Bend radius for 2mm sheet metal.

Bending radius there should have bending radius for sheet metal bending bending radius should not be too large or too small it should be chosen appropriately. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. The thickness of the metal. Let s say i have a 2 mm thick sheet and i want to bend it.

I can now see that the minimum flange length is 8 5 mm for such a bend so i have to keep it in mind when designing. If the bending radius is too small the bending will be cracked and if the bending radius is too large the bending is easy to rebound. Let s start with 90 degrees bend which is the most simple scenario. The hardness of the metal.

To keep it simple i also use a 2 mm inside radius. An air bend force chart or force chart breaks down a number of key components of sheet metal bending in an easy to reference format. Bend radii minimum bend sizes. The material thickness will be measured in decimal form not by the gauge number.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Discover all our calculation tools in the calculators section of the top menu. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. If the bending radius is too large it is easy to rebound.

Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. The required die width is 12 mm and tonnage per meter is 22. The bending tool has a radius of 30 mm which means that our inside bend radius r is 30 mm.

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. The bending radius should not be too large or too small and should be chosen appropriately. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. Use this document to choose values that are both manufacturable and meet your needs.

This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent. When the sheet metal is bent a bend radius is required at the bend. We are going to review three bending scenarios with three different bending angles. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance.

Generally speaking the thicker a piece of sheet metal is the wider the internal bend radius will. If the bending radius is too small it will cause cracking at the bend position.
