Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket
SHEET METAL BRACKET DESIGN USING NX
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 increase durability of the bracket
INTRODUCTION
Sheet metal is defined us the thin sheet which made by alloys according to needed parameters .Those sheets are undergoes bending , forming , cutting, enclosing etc .
Sheet metal usage is increasing every day to life including kitchen appliances to rocket spacing every its used to fabrication of surfaces in every industries . Thin sheet metals are also known as coils and foils .
Sheet metals play a major role in automotive industries for making a surfaces of Every automobiles
Siemens Nx formerly Unigraphics is a power full CAE/CAM/CAD Tool used for every phases of engineering including Design , Analysis , Manufacturing , A class surface design .
Design Approach /Methodology
The design approach is sheet metal design in NX sheet metal work bench
Features and tools used for design
Sketch tools
- Line tool - Line tool is used to create a straight line according to coordinate system
- Rectangle - To create a rectangle on a coordinate system
- Circle - create a circle according to face and plane which we selected
- Rapid dimension – Rapid dimension is too make a dimensions of sketch
- Angular dimension – Make dimension between angular coordinates
Sheet metal features
- Bend – In sheet metal basic principal is to be bending and unbend for the case bend feature used to make bend in sheet metal according to sketch
- Normal cutout – It is used to make a cut out using given diagram
- Break corner – Command used for make a fillet at the sharp edge corner sheet metal
- Contour Flange- It’s a command is used to make a sheet metal extrusion by using defined sketch as per requirement
- Unbend - It used to make a flat sheet metal features which we make
- Hole – Hole feature is to create the holes in the parts or components like countersink ,counterbore and threaded bore operations
- Bead – It is same as dimple but it lifts the contour of the sketches to asses stamping
- Flat Pattern- Flat pattern it creates a flat pattern according to the flat surface we selected
PROCEDURES TO MAKE ODD ENCLOSURE
- 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
- Followed with contour flange in reference as top plane create a drafting for normal cut for make bracket
- Using normal cutout command make cutout according to 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 un bend
- Create a hole for fasteners mount
- Prepare a drawing sheet for Manufacturing process
Finishing the all 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 technical parameters need to consider .
