SHEET METAL BRACKET-II DESIGN USING SIEMENS NX CAD

Objective

The objective of this project is to design a Sheetmetal Bracket using Siemens NX Sheetmetal Workbench.

Introduction

A bracket is any intermediate component for fixing one part to another, usually larger, part. What makes a bracket a bracket is that it is intermediate between the two and fixes the one to the other. Brackets vary widely in shape, but a prototypical bracket is the L-shaped.

Design Methodology

DESCRIPTION

1. SKETCH

It is the 2D representation of the model with respect to the plane/view.

2. CONTOUR FLANGE

Creates a base feature by extruding a sketch along a vector, or adds material by sweeping a sketch along an edge or chain of edges.

3. NORMAL CUTOUT

It cuts the model perpendicular to the sketch.

4. BREAK CORNER

Rounds or Chamfers a sharp corners of a tab or flange.

5. NORMAL CUTOUT

6. BREAK CORNER

7. UNBEND

Flattens a bend and the material adjacent to the bend.

8. NORMAL CUTOUT

9. REBEND

Restores an unbend feature to its previous bent state, along with any features added after the unbend feature.

10. BREAK CORNER

11. ADVANCE FLANGE

Adds a flange along an edge using a bend angle or a reference face. the edge and reference face can be curved.

12. UNBEND

13. HOLE

Adds a hole to one or more solid bodies in a part or assembly.

14. NORMAL CUTOUT

15. ADVANCE FLANGE

16. REBEND

17. GUSSET

Gussets are used to strengthen a flange without the need for secondary processes such as welding. A general guideline suggests that the width and depth of the gusset at an angle of 45 degrees is directly proportional to the radius and material thickness.

18. FLAT PATTERN

Flat Pattern tool is used to automatically create a flattened version of a sheet metal part and prepare the model for manufacture. The Flat Pattern feature remains the last feature in the Model tree and maintains the flat model view.

DRAFTING

Drafting is a term that refers to creating technical drawings that communicate how something is constructed or functions.

CONCLUSION

Successfully designed a Sheetmetal Bracket Design using Siemens NX Sheetmetal workbench.
