Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket

TO DESIGN A SHEET METAL BRACKET BY USING SIEMENS NX CAD

Objective:

The main aim is to design sheet metal bracket by using NX CAD.

Introduction:

To design a bracket in sheet metal, brackets are used to support and holding the load like a fixture. Brackets need more strengthening to withhold the weight of the objects.

Wall mounted brackets are used for tv mount, door handles, etc.,

Design methodology:

Features used for design a casing:

• Sketch
• Contour flange
• Create sketch for normal cutout
• Normal cutout
• Break corners
• Create sketch for bead
• Unbend the sheet metal
• Bead feature
• Rebend the sheet metal
• Holes
• Flat pattern the sheet metal
• Add drawing sheets to model

Sketch:

To setup the coordinate system and draw a sketch by giving dimensions and constraints to the plane, in this model to use origin point and make the sketch portion by using tools like

• Line
• Curve

For sketch by given dimensions for contour flange.

Contour Flange:

To add contour flanges to sketch model for required thickness and direction.

Sketch for normal cutout:

To create sketch constraints on the XY plane for normal cutout.

Normal cutout:

To add this feature for to remove the unwanted portion from the sheet metal.

Break corners:

To add this feature to transition the edges into smooth fillets by giving radius to the sheet metal.

Sketch for bead:

To add create sketch on the required plane for creating bead by giving the sketch constraints.

Unbend:

To unbend the model for further operations by selecting the center face for unbend the sheet metal.

Bead:

To create a bead on the sheet metal for providing addition strength to the model.

Rebend:

To rebend the model by selecting the feature and make select stationary face and drag the left mouse button on the model.

Create holes:

To create holes on the plane by giving sketch pointers and add diameter to them.

Flat pattern:

To flat pattern the model for drafting and manufacturing purpose.

Drafting:

To adding into drawings file for manufacturing the model by referring dimensions.
