DESIGNING a CASING using SIEMENS NX 12 0

Casing Design

OBJECTIVE

To design a casing using NX sheet metal application as shown in the above figure.

INTRODUCTION

The sheet casing structure design is obtained using sheet metal application in NX12 application. Various features such as flange, tab, dimple is used while creating the above model.

METHODOLGY

STEP1: create tab

STEP 2: create bends on each sides of the sheet.

STEP 3: create flanges on both sides (hem flange)

Step 3: mirror the body with respect to the required axis.

Step 4: create sketch on a plane with a particular offset from base, and create tab.

Step 5: create a dimple with sketch on either side of the box.

Step 6: unbend the sheet.

Step 7: create sketch for the hinge and normal cut the profile.

Step 8: re bend the sheet.

Step 9: create beads at the bottom for the support.

DESCRIPTION

TAB: it is used to create the base feature of a sheet metal

FLANGE: it is used to create an extended feature for the sheet metal

SKETCH: it’s a basic drawing in which any kind of operation can be performed, with reference to it.

UNBEND: it’s a command which is used to unbend the sheet metal with respect to a stationary face.

DIMPLE: used to create pitch down or pitch up on a surface with help of a sketch.

REBEND: its used to bring back the old bends which were bent before.

BEEDS: used for giving more strength for the sheet metal.

MIRROR FEATURE: used to create the same replica of the selected features with
