The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
Minimum radius on bending 6mm steel sheet.
Each and every bend in a piece of sheet metal has a certain minimum internal radius that needs to be taken into account when planning the design of a sheet metal form.
Thick grade 350 and 400 may have a minimum bend radius of 2 5 times the material thickness when transverse bending while longitudinal bending may require a minimum bend radius that s 3 75 times the material thickness see figure 1.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
If a piece of material is bent too tightly problems can occur.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal.
Use this document to choose values that are both manufacturable and meet your needs.
Maximum dimensions are 2980 x 1200 mm.
The bending of sheet metal with a punch and an array mounted at a folder is quite natural and normal.
It is possible to choose other bends if you require but additional lead time and tooling charges may apply.
By multiplying the material thickness by 0 63 63 percent the natural minimum radius can be determined in this case 0 063 in.
Maximum sheet thickness for all other steel is 6 mm.
Let s say i have a 2 mm thick sheet and i want to bend it.
In steel between 0 5 and 0 8 in.
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.
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.
Discover all our calculation tools in the calculators section of the top menu.
To keep it simple i also use a 2 mm inside radius.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
Bend radii minimum bend sizes.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
These dimensions are all in relation to a 90 angle.
Picture a sheet of 0 100 in thick material 2 54 mm.
These formulas are valid but they do not take into account whether the bend to be produced is a sharp or radius bend.
If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in.
The minimum inside bend radius is even larger when bending with the grain.
The problem with bending too tightly.
Maximum weight is 40 kg.
