Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket
1. Title: Bracket
2. Objective: To design the Bracket with sheet metal from NX CAD
3. Introduction: The sheet metal working domain is widely used in industries because sheet metal can quickly get and does not require any type of machining process like turning, milling, boring or any other kind of process which can be done with the help of CNC or VMC machine. In the Sheet metal process, the power utilization and material wastage are very less. So it is money and time saving also, by which the cost of sheet metal parts little bit reduces. We can manufacture a part which will have good strength and rigidity like a part modelling.
The Bracket name is suggesting to make a sheet rigid like structure by sheet metal with respect to manufacturing process and use that bracket to hold the compnents together or supporting structure or other.
4. Design Approach:
--Draw the contour Sketch which is 340 mm long and 20 mm hight.
-- use contour flange and extrude 200 mm width and 3mm thickness.
-- Draw 255x100 rectangle from any side corner of sheet .
-- Normal cut of 30 mm long.
-- Break the small corner of 25 mm.
-- Break the inner side corner of 30 mm.
-- Break the Outer side corner of 60 mm.
-- Unbend the sheet with respect to their folding edges.
-- Draw the line of 255 mm long offset from origin x 40 and Y 150
-- Create the bead 7mm depth 7mm radius and 5mm die radius.
-- Rebend the sheet from bending edges.
-- Create 3 holes for fastening.
-- Flat pattern to make drafting
5. Description:
Sketch: 2d sketch drawn for making the sheet metal of 1 mm and other features like dimples, and beads.
Normal Cut: Cut the sheet according to the requirements.
Bend: bend the sheet with respect to their bending lines.
Contour Flange: make the sheet from some complex shape sketches according to the requirements.
Break the corner: rounded shape the edges.
Unbend: Make the flat sheet metal plate.
Hole: To make the hole for fastening the bolts & nuts.
Beads: To make this is also made to emboss the structure but a circle sketch is required.
Rebend: Rebend the sheet metal with respect to its bending edges.
Flat Pattern: To make flat sheet metal for drafting details.

8. Conclusion :
From Bracket tutorial ,i have learned that how to use the contour flange and how to provide the strength to sheet. Now we will manufacture this type component for different type purposes.
