Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket

                                                     DESIGN OF SHEET METAL BRACKET USING NX CAD

OBJECTIVE :

  The objective of this project which make a sheet metal bracket which including bending and stiffening process by using Bead to provide a extra stiffening for the metal bracket increases durability of the bracket.

 INTRODUCTION :

 Sheet metal defines us the thin sheet which made by alloys according to needed parameters. Those sheets undergoes bending, forming, cutting, enclosing etc,.

 Sheet metal usage is increasing everyday to day life including kitchen appliances to rocket spacing every its use to fabrication of surfaces in every industries. Thin sheet metals are also known as coils and foils.

 Sheet metal plays a major role in automotive industries making surfaces of every automobiles.

DESIGN APPROACH/METHODOLOGY :

The design approach is sheet metal design in NX sheet metal workbench.

 

FEATURES AND TOOLS USED FOR DESIGN :

SKETCH TOOLS :

1. Line Tool - Line tool is used to create a straight line according to coordinate system.
2. Rectangle - To create a rectangle on the coordinate system.
3. Circle - To create a circle according to face and plane which we selected.
4. Rapid dimension - Its used to make dimensions for a sketch.
5. Angular dimension - Makes dimension between angular coordinates.

SHEET METAL FEATURES :

1. Bend - In sheet metal basic principle is to be bending and unbend for a case, bend feature used to make bend in sheet metal according to sketch.
2. Normal cutout - It is used to make a cutout using given diagram.
3. Break corner - Command used for making a fillet at the sharp edge corner sheet metal.
4. Contour flange - This command is used to make a sheet metal extrusion by using defined sketch as per requirements.
5. Unbend - It is used to make a flat  sheet metal which we make.
6. Hole - It is used to create hole in the parts or components like countersink, counter bore and threaded bore operations.
7. Bead - It is same as dimple but it lifts the contour of the sketches to assess stamping.
8. Flat pattern - Flat pattern, It creates flat pattern according to the flat surface which we selected.

PROCEDURE :

• Create a sketch in ZX coordinate system, after that make a contour flange.
• In before all to create preference about making a sheet thickness and bend radius according to the purpose.
• Followes with contour flange in referrence as top plane create a drafting for normal cutout for making bracket.
• Using normal cutout command make cutout according to the requirement.
• Make a sketch for bead with out unbend the sheet , bead used for stiffening purpose.
• Followed with drafting unbend the sheet , create a bead and make it unbend.
• Create a hole for fasteners mount.
• Prepare a drawing sheet for Manufacturing process.

Finishing all the steps , create a flat pattern option feature to make flat view 

DRAFTING A SKETCH SHEET :

Import a flat pattern view to the A4 drawing sheet in NX. In orient view make flat pattern view fixed with the sheet by rotation.

After making drafting save the sheet.

CONCLUSION :

  End of the project have a hands on experience about creating sheet metal Bracket with the techincal parameters need to consider.
