Bend Radius Copper Sheet

The first uses bending springs and the second a pipe bending machine.

Bend radius copper sheet.

If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured. For steel the factor is 1. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. If copper has to be bent a factor of 1 5 must be used.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. First we must start with the k factor. Table 1 preferred recommended 90 degree bend radii for various sheet metals. Most copper pipe tube can be readily bent and two main methods are employed.

The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. As a general rule the minimum bending radius for copper bar is equal to the thickness of the bar. The minimum bend radius data shown in these charts is measured to the inside of the bend.

What is the minimum radius. Tube and pipe bending. In this case the minimum radius equals the respective sheet thickness. Recommended minimum bend radii for steel and aluminum.

It is the smallest inside bend radius that you can place in a piece of material before the tensile forces on the outside of the bend begin to tear the grains in the material apart. It is normally expressed in terms of multiples of the material thickness e g. Specifing a bend radius from here will help prevent hair line cracks. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance.

The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius. If the punch nose radius. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

We want to know the final length of the detail. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried.
