All types of sheet metal forming processes are designed to create a shape out of a flat piece of sheet metal. They are designed to be completed at room temperature, which means no distortion of the sheet metal during the process.
There are different options in sheet metal forming that are included in this category. Some processes, like sheet metal stamping, force the sheet metal through a single die or a series of die to create complex shapes and designs. Other options, such as press brakes, are used to create a bend or an angle in the sheet metal that can range from simple to more complex.
The Use of a Sheet Metal Brake
The sheet metal brake uses high pressure to bend the sheet metal against a straight edge or an angle to create the shape. Depending on the specific sheet metal press brake, there is a clamping bar that holds the sheet metal and prevents it from sliding backward during the bending process.
The press then forces the metal to bend against the edge, creating any specific angle required. Different edges can be added to allow for the formation of various angles.
In addition to a simple bend, the brake press sheet metal forming process can also create metal boxes or pans. This is sometimes known as a finger brake or a box and pan brake, and it’s an extremely cost-effective way to create a square or rectangular box shapes that can be finished by welding, fastening, or soldering the edges in place.
