DESIGNING SHEET METAL BRACKET IN NX SOFTWARE

Objectives:

• To design sheet metal bracket in nx cad.
• Study about Bead and Holes used in Sheet metal design.
  

Introduction:

In this report, we are designing the sheet metal part from given drafting of thickness 3mm. Adding bead feature to the part in such a way that its stiffness should increase.

Design methodology

• Drawing the sketch of model with given data on XZ plane
• Using Contour flange command converting sketch into sheet metal of thickness 3mm
• Making normal cut-out to the part to remove unwanted material from model
• using Break corner command adding or removing the sharp corner of model
• Unbending the part to add some more features
• Adding the Bead to the Model to increase it's stiffness.
• Rebending the model
• Adding hole to the model
• Making flat pattern to do the drafting.

Description of the tool used.

DATUM PLANE: - It provides an axis on the work base.

SKETCH: - By the help of this tool 2D sketch to be drawn to get the desired shape.

DESIGN PARAMETER: This allows us to set the value of Material Thickness, Relief Depth, Bend Radius, Relief Width, K-Factor.

NORMAL CUTOUT: It allows making holes as per the sketch and removing materials.

BENDING: It allows to bend materials from edges.

COUNTOUR FLANGE: By this tool Created a base feature by extruding along the vector sketch.

UNBEND: It's do flatten bend.

HOLES: It allows to make symmetric standard holes.

DIMPLE: It is used to lift an area in the Closed sketch of the model.

BEAD: It provided to apply stiffness to the surface ( Formed), get oval shape ( Lanced), get oval shape with relief angel ( Punched).

DRAFTING (BASE VIEW): It is used to get detail sketched.

FLANGE: Used to create the flanges of required length and the angle and bend radius.

UNBEND: Used to flatten the sheet metal on give base surface.

BEAD: It is used to create a stamping effect inside or to outside of the sheet metal.

HOLE: It creates a hole of required dia on the selection of the location of the point.

REBEND: It is used to get the sheet metal to its original shape after bending it.

Flat-Pattern: It is used to create a flat surface on the selection of base surface which can be used for the drawings.
