Advanced Sheet Metal Design Using NX Cad - Metal bracket-II

Designing of a Metal Bracket

Objective: To design a ‘Metal Bracket’ using Siemens NX Sheetmetal Application.

Introduction: For studying different tools and features used for designing sheet metal design parts, this project was selected. This project was mainly focused in providing an idea about the workflow in creating a part design and to familiarize certain tools in this application.

Design Methodology:

As shown in the flowchart, I started by sketching the base feature and it was constructed by using the contour flange. Then by adding normal cut out the shape of bracket was produced. After unbending certain feature like Break corners, advanced flanges and holes were applied on the base feature. Then it was rebended and required gussets were applied. A flat pattern was applied for creating a draft image.

Description:

For designing of a Metal Bracket, the following features were used:

1. Contour Flange: To create a main base flange by extruding a sketch.
2. Advance Flange: To add a flange along a edge using bend angle or a reference face.
3. Break corner: To round the sharp edges of tabs and flanges.
4. Unbend: To flatten the bend features.
5. Normal Cut-out: To create a cut based on the sketch input.
6. Gusset: To create a stiffening gusset on bends.
7. Rebend: The unbended features are bended using this feature.
8. Flat Pattern: Used to create a flat pattern for draft purposes.
