TITLE: Sheet metal design of BRACKET.

OBJECTIVE: To design a sheet metal Bracket from a 2D sketch with help of NX CAD tool features.

INTRODUCTION:

In this project convert the 2D sketch to 3D and add the advanced features to get strengthen the bent portions.

For this project, I have chosen the NX tool with help of advanced sheet metal design features.

DESCRIPTION:

FEATURES USED:

SKETCH: This is used to create a basic sketch of the design on selecting the desired plane, then later it can be modeled for the requirement.

CONTOUR FLANGE: It is used to create a model of sheet metal by selecting the sketch.

NORMAL CUTOUT: This feature is used to cut the portions of the sheet metal by giving sketch curves.

BEND: This feature is used to bend the sheet metal along the sketched curve upon our requirement.

BREAK CORNERS: Break corners is used to make the edges round for easy handling when using.

UNBEND: Unbend is a feature used to analyze the model whether it has perfectly assigned the alignments, which ensures for the modeler to do further operations on it.

HOLES: Make holes on the sheet metal by selecting the points located on the sketch.

GUSSETS: It is used to strengthen the flange without the need for secondary processes such as welding.

REBEND: This is used to re-bend the object after all conformations.

ABOUT GUSSET:

As per the guidelines that the width and depth of the gusset at an angle of 45 degrees is directly proportional to the radius and material thickness.

t = Sheet metal thickness, h = depth of gussets, W = width of gussets

A certain distance must be maintained between a hole and gusset to avoid metal deformation and fracturing. It is recommended that the minimum distance between hole edge to gusset should be at least eight times the material thickness.
