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

Design of Metal Bracket-II using NX 12

Objective:

• To Design the metal bracket as per the given diagram and dimensions
• Make the Flatpattern
• Make a 2D drawing

Introduction:

In this exercise a metal bracket is designed according to the given dimensions in the drawing. All the holes and flanges are made according to the given dimension.

Design Methodology:

Start by making a sketch --> 

Step 1:

Step 2:

Use Countour Flange option to make a flange using above sketch. Width--> 158mm

Step 3:

Make another sketch on the YZ-plane:

Step 4:

Use Normal Cutout option to cut the part as shown

Step 5:

Make a new sketch on the YZ-plane:

Step 6:

Use Normal Cutout to cut the part

Step 7:

Make a new sketch on the YZ-plane:

Step 8:

Use normal cutout to remove the part as shown

Step 9:

Make a new sketch on YZ-Plane. Make Circles and a square

Step 10:

Use normal cutout to cut the circle and holes and the square.

Step 10:

Use Break corner option to round the corners of the square cut out: radius-->4mm

Step 11:

Unbend the part 

Step 12:

Make a circle on the unbend part:

Step 13:

Use normal cutout to cut the part as shown in the figure and rebend the part.

Step 14:

Use break corner to round off the corners

12mm at the bottom and 5mm at the top.

Step 15:

Use advance flange option to make a flange on the top:

Step 16:

Unbend the part again with flange as well

Step 17:

Make two points for making holes:

Step 18:

Make two holes using hole option --> Type: General Hole --> Form: Simple --> Diameter: 6mm --> Depth Limit: Through body.

Step 19:

Make a new sketch on the unbend part on the YZ-plane:

Step 20:

Use normal cutout to make a cutout using the sketch

Step 21:

Use Advance flang on the above normal cutout. Length --> 4mm

Step 22:

Rebend the entire part.

Step 23:

Make 4 gusset on the bottom portion of the part:

Step 24:

Make a Flatpattern using flatpattern option

Description:

1. Sketch: For making sketches.
2. Line: for making straight lines.
3. Circle: for making circles.
4. Hole: For making holes.
5. Point: For marking points in sketch.
6. Normal CutOut: For cutting a portion of the part using a reference sketch.
7. Advance Flange: For making a flange on any type og curve.
8. Unbend: To unbend the part.
9. Rebend: To rebend the part.
10. Gusset: To make a stiffening on the bend part.
