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

METAL BRACKET

OBJECTIVE

To design a metal bracket from a 2D drawing

METHODOLOGY

DESCRIPTION

Step 1: Sketching

A sketch is drawn on the yz-plane for the front view and another on the xz plane.

Step2: Flanging and cutting

Feature Used: Flange & Normal cut

A contour flange of width of 158 mm and 3mm thickness is created from the previous sketches

The top edges are normal cut for a depth of 120 mm and 49 mm

Step 3: Breaking the corners and cutting

Feature Used: Break corner & Normal cut

The corners are broken for 4.5 mm radius and again normal cut for 60 mm depth.

Step 4: Unbending and sketching

Feature Used: Unbend

The model is unbent to sketch the bottom hole on yz-plane and normal cut for 36 mm depth.

Step 5: Re-bending and sketching

Feature Used: Re-bend & break corners

The model is re-bent and the corners are bent for 10 mm, 5 mm and 12 mm. An advanced flange is added to the top for 5 mm.

Step 6: Adding gussets

Feature Used: Holes & gusset

Two holes of 6 mm diameter are created on bottom face and two pair of gussets are created for a depth of 5 mm, die radius 2 mm, width 8 mm and side angle 45° along the bends.
