Advanced Sheet Metal Design Using NX Cad Challenge_7_ Metal bracket-II
DESIGNING OF SHEET METAL BRACKET USING NX CAD
OBJECTIVE:
To design sheet metal Bracket as per requirements using siemens NX-CAD.
INTODUCTION:
Sheet metal is metal formed by industrial process into thin flat pieces.Sheet metal is one of the fundamental form used in metalworking and it can be cut and bend into variety of shapes.The thickness of the sheetmetal varies from 0.5mm-6mm.Sheet metal can be made from variety of material including aluminum,steel,copper etc.It is extremly strong and durable.
Siemens NX software is a flexible and powerful integrated solution that helps you deliver better products faster and more efficiently. NX delivers the next generation of design, simulation, and manufacturing solutions that enable companies to realize the value of the digital twin.
The sheet metal bracket are manufactured by stamping,Forging or die casting operation.These sheet metal bracket are used for many purpose such as mounting products like TV,antenna,projector etc.
DESIGN APPROACH:
DESIGN METHODOLOGY:
DESCRIPTION OF TOOL /FEATURES USED TO CREATE CASING DESIGN
Contour flange:
Creates a flange by extruding a sketch along a direction or add material by sweeping a sketch along a edge or chains of edges.Contour flange can also used as base feature of a new sheetmetal part or add the contour flange as secondary feature. .Contour flange is cerated only in opened sketch.
Normal cutout:
Cuts material by projecting the sketch on to the model and then cutting perpendicular to the faces intersect by the projection.
Break corner:
The break corner tool is used to remove the sharp edge and convert it to round edge.
Unbend:
This tool is used to flatterns a bend and the materials adjusent to the bend.To perform the un bend a stationary face must be selected which is the base of the sheetmetal and the other bends.Features such as cutout and holes can be added in this state of the sheet metal.
Rebend:
Restores an unbend feature to its previous bend state along with any features added after unbend feature.
Holes:
Add a hole to one or more solid bodies in a part or assemblies with the option for counterbore,countersunk and threaded.
Advanced flange:
Use this command to add flange along an edge using a bend angle or a referance face.The edge and referance face can be selected you can also select a single edge or a chain of tangent edge.
GUSSET:
It Is created at the bend between the adjcent walls.To create a gusset we have to select the bend and plane .It helps to add strength to the the sheet metal.
