Advanced Sheet Metal Design Using NX Cad Challenge_7_ Metal bracket-II

METAL BRACKET

OBJECTIVE

To create a sheet-metal design of a advanced metal bracket using the tools in SIEMENS NX 12.0 cad under the applications tab.

INTRODUCTION

The following sheet metal design is performed in NX 12.0 formerly known as ‘UNIGRAPHICS’. It is used in the mainly in Design; Engineering applications; Manufacturing sectors. Also known as CAD/ CAM/ CAE applications. It was founded in 1972 and became the world’s first CAM end user product.

Because it used by many industries and professionals for its reliability and performance ; also for its easy accessibility, it is still used and is successful for its output. Thus for performing my design I’ve used this software for its great accessibility.

DESIGN METHODOLOGY

DESCRIPTION

Using some basic advanced features in the Applications tab -> Sheetmetal. Some of the usually used features is listed as below:

1. TAB
2. FLANGE
3. NORMAL CUTOUT
4. BEND
5. BREAK CORNER
6. UNBEND
7. REBEND
8. HOLE
9. DIMPLE
10. BEAD
11. HEM FLANGE
12. CLOSED CORNER
13. UNITE
14. RESIZE BEND ANGLE
15. GAUSSET

TAB

This feature is used with sheetmetal thickness of 1 mm that is already set in the preferences under the menu. With this feature we can obtain thickness as set in the preferences box.

FLANGE

This feature is used to create a flange wherever necessary along the edges on the tab created in the previous step.

NORMAL CUTOUT

This feature is used to create a cutout blank out from the created sheet metal.

BEND

This feature is used to create a bend wherever needed over the sheetmetal along with a bend radius that is set in the preferences box earlier.

BRAKE CORNER

This feature is used to close all the sharp edges from harming whiling handling. In short this close to fillet.

UNBEND

This feature is used to make a flat sheet metal with all the changes made after the first step of TAB feature, so to transfer and understand the requirement of the necessary sheet metal by the production team.

REBEND

This feature is used to again bend the sheet metal to the necessary shape as it was before the unbend feature.

HOLE

This feature is used to create holes on the existing sheet metal .

DIMPLE

This feature is used to create a crate over the sheet metal tab created.

BEAD

This feature is used to create a bead that is nearly equal to Dimple feature.

HEM FLANGE

This feature is used to create a multiple 180 degree bend over the edge of the Sheetmetal.

CLOSED CORNER

This feature is used to create A Closed corner which is open using the adjacent bends.

UNITE

This feature is used to unite two bodies together.

RESIZE BEND ANGLE

This feature is used to repair or resize the angle of the bend that is previously created on the sheetmetal part.

GAUSSET

This feature is used to create a simple gausset in shapes including square, round which is mainly used at most times.
