Design of Bracket

ADVANCED SHEET METAL DESIGN USING NX CAD IN BRACKET DESIGN

OBJECTIVE:

Main objective of the project is to create a Bracket design in NX cad Sheetmetal platform, and learn about Sheetmetal feature in Creating to the bracket.

SOFTWARE USED: NX 12.0

• To design the Sheetmetal Bracket in NX by using some feature of Sheetmetal.
• NX Software is a flexible and powerful integrated solution that helps you deliver the products faster and efficiently way.
• NX Cad software is widely used in automotive, aviation, marine industry, thermal power station. Because of it is containing modelling, drafting and manufacturing platform.

INTRODUCTION:

1. Let’s get started how NX Cad software performing in Sheetmetal application. Sheetmetal fabrication is the process of forming metal sheets to the desired shape of the components using different types of manufacturing application.
2. Sheetmetal fabrication is the process of forming parts from a metal sheet by punching, cutting, stamping, and bending.
3. 3D files are converted to machine codes to control the machine movement to create the desired shape of the component.
4. There are different types of material are used in this fabrication process, such as ALUMINIUM, BRASS, COPPER, STEEL, TIN.
5. Sheet metal parts are known for their durability, which makes them great for durability, which makes them great for end use applications.
6. Because parts are formed from a single sheet of metal, designs must maintain a uniform thickness.
7. Be sure to follow the design requirements and tolerances to ensure parts fall closer to design intent and cutting sheets of metal.

DESIGN METHOLOGY: (BRACKET DESIGN)

DESCRIPTION:

In Sheet metal workbench Bracket creating to help of above mentioned featured. While designing the Bracket model in Sheetmetal workbench, there are multiple features are used to Create them.

SKETCH:

Sketch is used for creating the model by specify shape and dimensions.

SKETCH EXPLANATION:

• In this model we want to create a Contour flange, so that why we are creating the sketch option.
• User defined sketch is using in this contour flange feature.
• And add the dimension height(p0=20mm), angle(p1=140,p2=140), top line(p3=70mm), full length(p4=340mm), radius(Rp5,Rp8=30mm), radius(Rp6,Rp7=40mm).

CONTOUR FLANGE:

Creating a base feature by extruding a sketch along a vector, or adds material by sweeping a sketch along an edge or chain of edges.

CONTOUR FLANGE FEATURE EXPLANTION:

• We select the XZ plane for Creating to the User defined sketch for Bracket Design.
• And Select sketch to creating the contour flange by extruding.
• Add dimension for Base contour flange (Thickness=3mm), (Width option=finite), (Width=200mm)

Add the sketch to normal cutout option.

NORMAL CUTOUT:

Using the normal cutout option, it is used to remove the material from projecting a sketch onto the intersecting model.

NORMAL CUTOUT FEATURE EXPLANATION:

• Select the sketch and add the normal cutout feature, specify the depth value(35mm), if it is wrong direction to make it reverse direction to make the cut the material in right position.

BREAK CORNER:

Round or chamfers a sharp corner of the tab or flange feature.

BREAK CORNER FEATURE EXPLNTION:

• Break corner option (Blend) just create the round shapes in edges.
• Click the break corner feature and which edges you want to modify the round shape.
• Add the dimension of radius(25mm).

Add the Another break corner feature,

Add the Another break corner feature,

UNBEND:

Unbend feature is used to unbend the bended region in NX Sheetmetal workbench.

UNBEND FEATURE EXPLANATION:

• Unbend feature is to create the flattens the Bracket Sheetmetal.
• If the Unbend feature we are using it will Flattens the Sheetmetal and adjacent to the bend.

To add the sketch option to create the bead feature.

BEAD:

Bead feature is used to lift material along a contour of the sketch that stimulates the stamping tool.

BEAD FEATURE EXPLANATION:

• Bead feature is Lift the material along the contour of the sketch.
• Then specify the Cross section (Circular), Depth and Radius(7mm), End condition (Formed shape), Die radius (5mm), Minimum tool clearance(5mm).

REBEND:

REBEND option is used to unbend feature to its previous bent state, along with any feature added after the unbend feature.

REBEND FEATURE EXPLANATION:

• It is just Restores an unbend features to its previous bend state.
• And it is including to the any feature added to after the unbend feature.

Check the local radius analysis.

HOLE:

To create the holes in three corner Region.

HOLE FEATURE EXPLANATION:

• We need to first assign the sketches in above the Bracket feature.
• Then click the hole feature and specify the which type of hole you want to select the general hole option.
• And specify the position of hole feature, select the direction (normal to face), form(simple), Screw type (general hole), Diameter(20mm), Depth limit (through body), Boolean (subtract).

MEASURE DISTANCE:

Measure distance option is used to measure distances in specify starting and ending point.

MEASURE DISTANCE FEATURE EXPLANATION:

• Measuring the specify starting and ending point distance.
• Click the projected distance option, and specify the vector, starting and ending point.
• Measurement option to give distance in minimum.

FLAT PATTERN:

Flat pattern is used to create the Bracket to formed Sheetmetal part.

FLAT PATTERN FEATURE EXPLANATION:

• It is created the drafting of the Sheetmetal design.
• And it is show feature names to which feature you are using to create the model.

BRACKET VIEWS:

1.FRONT VIEW:

2.TOP VIEW:

3.RIGHT VIEW:

4.ISOMETRIC VIEW:

DRAFTING:

We can create the 2D Drawing sheet from Bracket model in NX Cad software.

DRAWING SHEET:

• Drawing sheet is used to represent the Sheetmetal model in 2D view(A4) help of NX cad platform.
• It is show the which feature you are using in this Bracket

DETAILED VIEW:

• Detailed view is nothing but it is just Show the recommended view from the model in single sheet(A4).
• You will see the detail view in A4 size sheet top, right, front, isometric views in detailed view

CONCLUSION:

• In this project creating the Bracket Sheetmetal design using NX Cad Siemens 12.0 version platform.
• So, Sheetmetal basic feature and tools are learning in this project.
• Designing the Sheetmetal in NX cad software, it is user friendly interface for Creating the Bracket design.
