Advanced Sheet Metal Design Using NX Cad Challenge_7_ Metal bracket-II

Title of the Project: SHEET METAL _ BRACKET

Objective: To Design an metal bracket using the sheet metal application in siemens NX.

Introduction: Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Thicknesses can vary significantly; extremely thin sheet metal is considered foil or sheet, and pieces thicker than 6 mm (0.25 inch) are considered plate steel or “structural steel”. And sheet metal design is a vast domain in the design of any sheet metal industry,it is used many sectors including the aeronautics & automotive sectors, in this sheet metal casing design we will look at the design approch using NX (CAD) SOFTWARE through various design , images , explaination and images.

Types of Sheet Metal

Aluminum
Alloy steel
Carbon steel
Tool steel
Galvanized steel
Stainless steel

Applications

• Sheet metal is used in automobile and truck (lorry) bodies, airplane fuselages and wings, medical tables, roofs for buildings (architecture), and many other applications.
• Sheet metal of iron and other materials with high magnetic permeability, also known as laminated steel cores, has applications in transformers and electric machines.
• Historically, an important use of sheet metal was in plate armor worn by cavalry, and sheet metal continues to have many decorative uses, including in horse tack.
• Sheet metal workers are also known as “tin bashers” (or “tin knockers”), a name derived from the hammering of panel seams when installing tin roofs.

Design methodology

Description (Tools/ Features used while designing):

Contour Flange, Creates a base feature by extruding the sketch along a vector or add material by sweeping the sketch along an edge.

Break Corners, This feature makes sharp edges to smooth round shape or to chamfer shape.

Cut a section out from the tab using the nomal cutout option . required surface was bend to the to make perfect shape of casing.
Flanges are added by 'flange command' to the corner for the gripment of privously bended surface.
Break corner option are usefull so that it make us to view neatly and smoothly it help to radius the sharp corner.
Unbend is done through unbend option will make the bended sheet metal to unflap to the size and shape of sheet to manageable requirement .
And the sketch is added to the surface to make the holes on it using hole option.

Gusset, Creates a stiffening gusset on the part.
