Advanced Sheet Metal Bracket Design Using NX Cad
Sheet Metal Design of Bracket Using NX CAD
Objective: To design a Sheet Metal Bracket Assembly by using Siemens NX Sheet metal workbench.
Introduction:-
Sheet metal enclosures are fabricated by 'cold forming', where the metal is clamped and bent in machines called 'press brakes'. As a result, metal typically cannot be formed into a true 90 degree corner. Instead, the corners are curved. You’ll find them in everything from junction boxes to control panels for industrial machinery. These enclosures are simple, versatile and extremely tough, so they’re in high demand for electrical projects and are often custom-fabricated.
Design Methodology
DESCRIPTION
Sketch: Sketch tool was used for creating the sketch required for tabs, cut outs, dimples, beads etc.
Contour flange: It is used for extruding a sketch along a specified vector to form a base feature.
Normal cut out: This tool is used to cut the material by projecting a sketch onto the model and then cutting normal to the faces intersected by the projection.
Break corner : It is used to round or chamfer the sharp corners of a tab or flange.
Bead: Beads are used to enhance the strength of the sheet metal part. It lifts the material according to a sketch that simulates a stamping tool. Here, four beads were used at the bottom of the box assembly.
Unbend: This feature is used to unbend the adjacent bends and flatten them.
Rebend: It is used to rebend the unbended corners after adding any features on the faces.
Hole: It adds holes on sheet metal part according to the specified sketch points.
Flat Pattern: After the object is completely finished and to produce the machining drawing we use flat pattern option to create the detailed flat sheet with all the features marked on it along with its description.
Drafting: We can convert the flatpattern of the model to a 2D draft on a drafting sheet.

CONCLUSION
This project underlines the tools and considerations for designing a sheet metal bracket. It also underlines sheet metal application in NX and advantage of NX as a software for sheet metal design and its application as bracket.
