TITLE - BRACKET DESIGN

AIM: Our aim is to create the sheet metal bracket design as per the engineering drawing given to us.

INTRODUCTION

Bracket is the sheet metal component whose surface area to thickness ratio is very high, it's purpose is to provide the common platform for the two or more than two component to join hence this is used extensively for the fabrication purposes and it comes under the temporary joint and here we are going to create the design of bracket in NX- SHEET METAL ENVIRONMENT.

DESIGN APPROACH

1- SKETCH

2-CONTOUR FLANGE

3- SKETCH ON THE TOP SURFACE

4- NORMAL CUT OUT

5- BREAK CORNER

6- UNBEND

7- CREATE THE BEAD CENTER LINE ( SKETCH)

8- REBEND

9- CREATE THE HOLE AS PER THE GIVEN DATA

STEP BY STEP PROCEDURE

1- CREATE THE SKETCH IN THE XZ PLANE AS PER THE GIVEN DRAWING'S DIMENSION AS SHOWN BELOW.

2- USING CONTOUR FLANGE COMMAND CREATE THE BASE DESIGN OF THICKNESS 3mm AND WIDTH OF 200mm.

3- CREATE THE L SHAPE SKETCH ON THE TOP OF THE FACE OF GIVEN DIEMENSION AS SHOWN BELOW.

4- USING THE NORMAL CUT OUT OPTION CUT THE UNNECESSARY PART AS SHOWN BELOW

5- USE BREAK CORNER COMMAND TO AVOID ANY SHARP EDGES BECAUSE OF THE STRESS CONCENTRATION ISSUE WE USE DIFFERENT VALUE OF BLEND RADIUS AS SHOWN BELOW.

6-IN ORDER TO CREATE THE BEAD WE NEED FLAT SURFACE SO USING UNBEND OPTION CREATE THE FLAT SURFACE AFTER THAT CREATE THE LINE ON THE TOP SURFCE AND USING BEAD COMMAND CREATE THE CIRCULAR BEAD.

7- IN ORDER TO GET BACK TO THE ACTUAL SHAPE WE USE REBEND COMMAND.

8- CREATE THE HOLE OF GIVEN DIEMENSION FOR THIS FIRST CREATE THE POINT ON THE DESIRED LOCATION AFTER THAT CREATE THE HOLE OF THE GIVEN DIEMENSION.
