Sheet Metal Bending Processing
Sheet Metal Bending Processing
The focus of the sheet metal fabricating industry has been on the automation of punching, shearing and bending process for sheet metal parts and minimal focus was on the sheet metal bending operation.
Simple metal brake bending is where the sheet metal’s shape is changed at only one axis point, whereas complex parts are created by applying additional operations to the piece. Sheet metal bending is used to create V, U or channel shapes that are created with help of brakes. One can not only create sheet metal parts in SolidWorks, but even take assistance for the sheet metal bending process. It helps you to achieve the exact requirements and tight tolerances, the one that your customer’s sheet metal product expects.
The word “bending” itself is an indication that it is not simple. When you ought to bending brake something, it’s going to be a bit difficult. There are multiple kinds of brake bending and each has its advantages and disadvantages. The key difference between each type of sheet metal bending is characterized by the relationship between the thickness of the sheet metal material and the end tool position.
Top two sheet metal bending techniques, and how are they utilized:
Air brakes bending forms the metal sheet material by pressing a punch, upper or top die, into the material; forcing it into a bottom V-die, which is mounted on the press. The opening of the bottom die should be chosen adequately depending on the thickness and bend radius of the sheet metal material. One of the good thumb rules is 6 to 12 times the material thickness. The drawback here with Air bending is that it is not great when it comes to angular accuracy. However; it accommodates several materials, material thicknesses and bend angles without retooling.
Bottoming is where a piece of sheet metal is forced against the “V” opening in the bottom of the tool to create the “V” shape. In this case the punch presses the materials against the inner surface of the bottom die, while the angle of the bottom tool defines the bend angle. It is more accurate and has less spring back than air bending. A rule of thumb says that 8 times the material thickness will make a good bottom die opening. This bending technique involves greater forces which makes it all the more important to use the right kind of dies. It requires separate lower dies and retooling for every bending angle as well as significantly more pressure, but now the bending technology already over your thinking, you can bend any shape you want with Metal sHEET cnc press brake bending machines, cnc adavcned multi-V controller, good performabnce for bending metal brakes job.
There are various other sheet metal bending techniques as well including; Coining, Folding, Wiping, Three-Point Bending, Rotary Bending, Elastomer Bending, Roll Bending and Joggling.
