Closed Sheet Metal Box Design

Next month concludes with the pros and cons of hems jogs and forming tools.

Closed sheet metal box design.

Bends in sheet metal are manufactured using sheet metal brakes. Drawing a sheet metal box in solidworks 2010. The box i have my students create in class ends up being 5 5 x 2 x 3 5. Sheet metal materials are the most commonly used materials in the structural design of communication products.

Understanding the comprehensive performance of materials and the correct material selection have an important impact on product cost product performance product quality and processability. The patterns for a cardboard box will look very similar to what you need to plan out for the sheet metal box. Columnist gerald davis continues a discussion of 3 d cad and precision sheet metal manufacturing in part iii of a four part series focusing on design guidelines for sheet metal. In this tutorial video i will sketch power box chassis in solidworks with the help of sketch and sheet metal tools i hope you like it.

Sheet metal tolerances are far more generous than machining or 3d printing tolerances. Factors affecting tolerances include material thickness machines used and number of steps in part production. To make things easy for my students i designed our classroom box so it would be able to work on the size of a standard 8 5 x 11 piece of paper. By adding cutouts for ports switches ventilation or mounting these versatile and cost effective enclosures can be used in applications ranging from electronics to robotics.

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. Please subscribe our c. A 1 degree tolerance on all bend angles. A press brake creates a bend by pressing sheet metal into a die with a linear punch so design does not allow the creation of closed geometry.
