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

SHEET METAL DESIGNING OF METAL BRACKET USING NX CAD

Objective :

To create a sheet metal model of bracket using sheet metal tools in NX CAD

Introduction :

Sheet Metal -

The sheet metal is formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metal working, and it can be cut and bent into a variety of shapes. The metals which are less 6 mm thickness are considered as sheet metals. The sheet metal is available in flat pieces or coiled strips.

The various forming processes that are used to deform the sheet metals are -

• Bending
• Curling
• Deep drawing
• Hemming and Seaming
• Punching
• Blanking and Peircing
• Rolling, Spinning and Stamping

Sheet metal is used in automobile and truck bodies, airplane fuselages and wings, medical tables, roofs for buildings and many other applications.

NX CAD in sheet metal -

NX sheet metal design software incorporates material and process information in sheet metal-specific modeling features: bends, flanges, tabs, cutouts, beads, dimples, louvers, corner and edge treatments, patterns and other formable features. You can also quickly convert solid models to sheet metal components, and create sheet metal parts that enclose other components.

NX Sheet Metal-specific features such as flanges, tabs, jogs, corner conditions, and drawn cutouts & many more along with productivity enhancements such as – automatic bend reliefs.

The software also provides common modeling features typically used in sheet metal design, such as holes and slots, as well as other essential capabilities such as copy, paste, and mirror.

The application provides defaults for sheet-metal-specific properties such as material – thickness, bend radius, and bend relief. You can easily change these defaults.

Design methodology :

Description :

Create contour flange by using drawing the outer profile of the bracket

Create the sketch for normal cut out

Normal cut out using sketch

Create the all normal cutout section apply blend edges on sharp corners

Unbend the sheet

Create a sketch an apply normal cutout

Rebend the sheet

Apply break corner

Create flange at top using advanced flange tool

Unbend, create the holes

Create ellipse and normal cut out it

Create flange

Create gusset
