Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket

Developing a Sheet Metal Bracket using NX CAD

Objective

The aim of the work is to create a bracket by using NX sheet metal applications.

Introduction

In this project, creating a sheet metal bracket from 2d drawing using NX CAD and the features like bead, hole, contour flange, unbend and rebend are added.

Design Methodology / Approach

Description (Need to explain tools / Features used while designing)

Step by step procedure developing a sheet metal bracket.

Step 1: Creating a Contour flange.

Figure 2: Contour flange

In ZX plane sketch is created and then contour flange feature is selected. Now select the curve and give the width 200 mm distance as shown in figure 2.

Step 2: Normal Cut-out

Figure 3: Creating a normal cut-out feature

After completion of contour flange select the top surface to draw a sketch entity and then use normal cut-out to remove the unwanted portion as shown in figure 3.

Step 3: Break corner at sharp edges

Figure 4: Break corner 25mm dia.

Select the edges and give the blend radius 25mm.

Figure 5: Break corner 30mm dia.

Select the edge and give the blend radius 30mm.

Figure 6: Break corner 60mm dia.

Select the edge and give the blend radius 60mm.

Step 4: Unbend

Figure 7: Unbend

Part is unbend to create a features on top surface.

Step 5: Bead

Figure 8: Creating a bead

Sketch is drawn on top of the surface and selected the sketch entity while using a bead feature. The parameters are shown in figure 8.

Step 6: Rebend

Figure 9: Rebend

Rebend to original position

Step 7: Hole

Figure 10: Creating a hole

First creating a point for holes then w.r.t to points the hole is created as shown in figure 10.
