Sheet metal box design guide.

In the original design sheet metal requires two bending processes. During bending the sheet metal must bridge fully across the v die see figure 2. If you can t visualize how the flat pattern for a box should look with sheet metal find an old shoe box or cereal box and unfold it. Bends can give strength and shape to a part and are formed in a machine using bend brakes.

Similarly the more complicated the sheet metal bending process the more material waste may be caused. In the workspace add desired custom features as needed. The v die is usually selected to be 5x to 8x the workpiece thickness. 3d cad files are converted into machine code which controls a machine to precisely cut and form the sheets into the final part.

Focus on the flange depth in the fab shop the v die width in the press brake limits the size of the flange that can be bent. Sheet metal fabrication is the process of forming parts from a metal sheet by punching cutting stamping and bending. Sheet metal design guidelines are followed to design quality sheet metal enclosures. The box i have my students create in class ends up being 5 5 x 2 x 3 5.

Following all sheet metal design guidelines is very difficult in the complex part. Sheet metal materials are the most commonly used materials in the structural design of communication products. Consider material and finishing options along with design elements like bends reliefs holes and slots when developing sheet metal components before diving into the details of sheet metal fabrication recognize a basic fact of all sheet metal parts. In the improved design the sheet metal only needs one bending process to complete the bending of the two sides at the same time.

From the list select sheet metal box. Bends in the same plane should be designed in the same direction. Since sheet metal cannot be bent to a 90 degree position without breaking at sharp corners all bends will have an acceptable bend radius. The most common sheet metal form is a bend.

They start out flat. Therefore exceptions can be there for complex features design. Selection principle of sheet metal materials. This helps in delivering the product at low cost and faster timelines.

Sheet metal fabrication our basic guidelines for sheet metal fabrication include important design considerations to help improve part manufacturability enhance cosmetic appearance and reduce overall production time.
