Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket

DESIGNING A SHEET METAL BRACKET using NX-CAD

Objective

To design a sheet metal Bracket in NX-CAD sheet metal spplication workbench and also creating the drafting of the Bracket.

Introduction

NX sheet metal design software incorporates material and process information in sheet metal-specific modelling features: bends, flanges, tabs, cutouts, beads, dimples, louvers, corner and edge treatments, patterns and other formable features. We can also quickly convert solid models to sheet metal components, and create sheet metal parts that enclose other components.

With NX sheet metal CAD tools, we can apply standard values, such as material thicknesses and bend radii, based on industry or company best practices. With folding and unfolding capabilities, we can work with models at any stage of the fabrication process. NX sheet metal software creates accurate flat patterns for documentation and manufacturing.

Design Methodology/Approach

Description

1. Sketch the drawing for the Bracket in XZ Plane

2. Use Contour Flange to give the thickess and body to the sketch of the Bracket

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. Draw another sketch on the XY Plane for the Normal Cutout

4. Create the Normal Cutout on the body to get the required shape of the Bracket

Normal Cut: Cuts material by projecting the sketch onto the model and then cutting perpendicular to the faces intersected by the projection.

5. Use Break Corner to smoothen the edges of the Flange with the required radius

Break Corner: Rounds or chamfers sharp corners of a tab or a flange.

6. Draw another sketch on the XY Plane for the Bead

7. Unbend the body for applying the Bead

Unbend: Flattens a bend and the material adjacent to the bend.

8. Apply the Bead with the proper parameters

Bead: Lifts material along the contour of a sketch that simulates a stamping tool.

9. Rebend the body to its previous shape

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

10. Skecth in the XY plane for the position for the 3 Holes

12. Create the Holes on the 3 specified points

Hole: Adds a hole to one or more solid bodies in a part or assembly with options of counterbored, countersunk and threaded

13. Create the Flat Pattern for Drafting the drawing sheets

Flat Pattern: Creates a flat pattern feature from the formed sheet metal part.
