Bending Copper Sheet

How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools.

Bending copper sheet.

When bending is done the residual stresses cause the material to spring back towards its original position so the sheet must be over bent to achieve the proper bend angle. It is important to make sure that the sheet is properly pushed onto the wipe die. Clamp the wood on top of the metal to the workbench. The amount of spring back is dependent on the material and the type of forming.

Next place the wood parallel and slightly behind the bending line. Subscribe my channel for more new videos. Hello friends today i make a sheet metal bending tool. Finally bend the sheet up by hand to the angle desired.

Mark a bend line and place the sheet metal on the edge of your bench. As a result the wipe die also determines the bend s inner radius. When sheet metal is bent it stretches in length. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.

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 you bend to a sharp inside corner with sheet metal you ll be adding a ton of internal stresses. I hope you like this video. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one.

The slack between the wipe die and the punch plays an important role in getting a good result. Even on malleable materials you can end up cracking the metal at the bend or weakening it to the point where it ll break with minimal force. Wipe bending or edge bending is another way to bend sheet metal edges. The solution is to have a radius on the tool that you ll be using to bend the metal.
