The bending of sheet metal with a punch and an array mounted at a folder is quite natural and normal.
Minimum radius on bending 6mm steel sheet.
The minimum inside bend radius is even larger when bending with the grain.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
Maximum weight is 40 kg.
The problem with bending too tightly.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
By multiplying the material thickness by 0 63 63 percent the natural minimum radius can be determined in this case 0 063 in.
To keep it simple i also use a 2 mm inside radius.
In steel between 0 5 and 0 8 in.
In principle does not seem that this operation is complicated and difficult.
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.
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.
Maximum sheet thickness for aluminum and stainless steel is 6 mm.
If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in.
Maximum dimensions are 2980 x 1200 mm.
Maximum sheet thickness for all other steel is 6 mm.
The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
Bend radii minimum bend sizes.
Use this document to choose values that are both manufacturable and meet your needs.
It is possible to choose other bends if you require but additional lead time and tooling charges may apply.
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.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
Let s say i have a 2 mm thick sheet and i want to bend it.
The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
If a piece of material is bent too tightly problems can occur.
These formulas are valid but they do not take into account whether the bend to be produced is a sharp or radius bend.
These dimensions are all in relation to a 90 angle.
