Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket

Objective:

Design of 3D model of bracket as per given drawing and drafting of flat pattern.

Introduction:

When molten metal is hot rolled into flat sheet which ranges from 0.5mm to 6mm thickness uniformly across the length termed as sheet metal. Below 0.5mm thickness termed as foil and above 6mm thickness categorised as steel plate. Application of sheet metal is very vast from industrial fabrication to aerospace industry. Various profile and increasing the local strength of structure is achieved by accommodating following sheet metal feature like flange, beads, coining, blanking, dimple, reliefs etc.

Here we are designing a bracket of a component from given drawing sheet metal parameter for 3mm sheet.

Design Methodology:

Tools used:

Sketch: drawing the side view profile

Counter flange: profile is extruded to 200mm for 3mm thickness

Normal cut-out: Project the profile on the face and cut the section from base model

Unbending: flattening the model to create feature.

Bead: unbend the model and create bead feature as per dimension

Rebend: Re-bend the model to 3D model

Holes: creating simple hole profile of 20mm size on the flat base.

Flat pattern: To obtain flat surface for drafting.
