Bend Table Sheet Metal

Understanding the bend allowance and consequently the bend deduction of a part is a crucial first step to understanding how sheet metal parts are fabricated.

Bend table sheet metal. To use the tables below. The bend radius of a sheet metal design will be based on the wall thickness of the part and the tooling that is available in house. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Sheet metal bend radius.

Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. The problem with a solidworks sheet metal bend table is that it can only control the bend allowance bend deduction or k factor but the thickness and radius is still free to be changed manually. Refer to the chart for values for folder as well as various press brake tooling combinations. Refer to table s for your choice of material.

Bend tables created as a text file support the following. The second important number when creating sheet metal designs is the bend radius value. You can generate flat patterns by unfolding sheet metal features using a uniformly applied. To create your own bend table copy and edit this bend table with any text editor.

When unfolding if a bend radius or angle does not correspond to a specific entry a process interpolates between adjacent values in the table. Geometry of tooling imposes a minimum bend dimension. Since gauge tables were introduced all the parameters can be controlled base on the drop down selection which makes life much easier. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

Each column specifies a bend radius. Exemple 1 for metal sheet bending tables. We have a metal sheet of 3 m m thickness in iron with a hardness of 42 48kg mm2 if we go to the top of the table we see the thicknesses in brown we look at the 3 thickness of the sheet and we go down to the blue box we see a value of 240 this is in kn mm2 and if we take a 0 it will be in ton. A bend table is a table of bend deductions arranged in rows and columns.

0 060 crs 2 000 2 000 r0 031 aluminum 90 deg. The diagram shows one such mechanism. Bend allowance mild sheet steel 90 degree bend allowance bend allowance chart example flat size 2 2 095 3 905. A section view of a typical punch and die set used to create sheet metal bends.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Understanding the bend deduction and consequently the bend allowance of a part is a crucial first step to understanding how sheet metal parts are fabricated. All bend table types bend deduction bend allowance and k factor.
