Sheet Metal Box Design Guide

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 box design guide.

3d cad files are converted into machine code which controls a machine to precisely cut and form the sheets into the final part. In the original design sheet metal requires two bending processes. Sheet metal boxes are two part enclosures made by cutting metal sheets and then bending the resulting parts using a press brake to form a box. The v die is usually selected to be 5x to 8x the workpiece thickness.

Following all sheet metal design guidelines is very difficult in the complex part. Sheet metal fabrication is the process of forming parts from a metal sheet by punching cutting stamping and bending. Understanding the comprehensive performance of materials and the correct material selection have an important impact on product cost product performance product quality and processability. During bending the sheet metal must bridge fully across the v die see figure 2.

Bends can give strength and shape to a part and are formed in a machine using bend brakes. Sheet metal materials are the most commonly used materials in the structural design of communication products. This helps in delivering the product at low cost and faster timelines. The most common sheet metal form is a bend.

Bends in the same plane should be designed in the same direction. In the workspace add desired custom features as needed. From the list select sheet metal box. Therefore exceptions can be there for complex features design.

Selection principle of sheet metal materials. Similarly the more complicated the sheet metal bending process the more material waste may be caused. Enter the desired parameters and click ok. In the improved design the sheet metal only needs one bending process to complete the bending of the two sides at the same time.

Since sheet metal cannot be bent to a 90 degree position without breaking at sharp corners all bends will have an acceptable bend radius. Sheet metal design guidelines are followed to design quality sheet metal enclosures.
