Advanced Sheet Metal Design Using NX Cad Challenge_7_ Metal bracket-II
* Title : Report on Sheet Metal bracket.
* Objective : To perform a detailed report on Sheet Metal Component with good explanation of Sheet Metal Bracket.And on the Sheet Metal modelling tools applied throughout the modelling.
* Introduction :
* Open NX cad and start with new.
* Now,sketching the model ,performing of contour flange ,normal cutout and brekcorner .
*Moreover, performing of Unbend and rebend ,holes as required for sheet metal bracket.
* Attaching the different views of model and saving .
* Design methodology :
| 1. Opening the NX cad and new file. |
| 2. Sketching and performing of Contour flange. |
| 3. Performing of different options like Normalcutout ,breakcutout,unbend and holes. |
| 4. Saving the file and closing . |
* Description :
* Open NX CAD ,click to new and start with new file as required name.
* From construction tool bar ,select sketch and click to plane .
* Now in sketch ,select line and sketch with required parameters for sheet metal bracket as shown below.
* As hown above draw a line of 80 mm to 90 degree ,a line of 54.2 with angle 145 and finallly a line of 25.8 mm with angle of 44 degree as shown below.
* Selecting the required plane .
* Model after Sketching .
* Performing of contour flange .
contour flange : The that creates a base feature By extruding a sketch along a vector or adds a material by sweeping a sketch along an edge or chain of edges .
* Here after sketchig click finish in sketch tab and select Contour flange,moreover select sketch which need to be flanged .
*In contour flange ,give thickness as 3mm and width as 158mm ,click ok .
* Model before performing contour flange :
* Model after performing contour flange :
* Performing of unbend :
Unbend : The process that flattens the bend and the material adjecent to the bend .
* From tool bar select unbend and select the a face which is to be represented .
*Furthermore,select the face which need to flatten and click apply as shown below .
* Model before performing unbend:
* Model after performing unbend:
* Sketching for performing Normalcutout.
*From construction tool select sketch and start with drawing line .
*Sketch according to the required dimension as shown below .
* Model before sketch :
* Model After sketch :
* Performing of Normal cutout :
Normal cutout: The method that cuts material by projrctiona sketch onto the model and then cutting perpendiculr to the faces intersected by the projection.
* Select normalcutout from base and select the face .
*Now,select the sketched line which need t be trimed as shown below .
* Sketch :
* Model before using Normalcutout :
* Model after using Normalcutout :
* Performing rebend :
Rebend : The process that restores the unbend feature to its previous position ,along with any features added after the unbend feature .
* From bend tool bar,select rebend .
*Now,select the surface which need to be performed rebend and click apply as shown beow .
* Model before performing rebend :
* Model after performing rebend :
* Performing of unbend for performing holes :
Unbend : The process that flattens the bend and the material adjecent to the bend .
* From tool bar select unbend and select the a face which is to be represented .
*Furthermore,select the face which need to flatten and click apply as shown below .
* Model before performing unbend:
* Model after performing unbend:
* Performing of Holes :
* select sketch from construction tool bar .
* Draw a circle with 51mm dia by selecting circle ,with given dimension and click finish.
*And draw a rectangle too with dimension of 11mm*8mm as shown below .
*Sketch according to the required dimension as shown below .
* Model before sketching :
* Model after sketching :
* Performing of Normal cutout :
Normal cutout: The method that cuts material by projrctiona sketch onto the model and then cutting perpendiculr to the faces intersected by the projection.
* Select normalcutout from base and select the face .
*Now,select the sketched line which need t be trimed as shown below .
* Model Before normalcutout :
* Model After normalcutout :
* Performing of Normal cutout :
Normal cutout: The method that cuts material by projrctiona sketch onto the model and then cutting perpendiculr to the faces intersected by the projection.
* Select normalcutout from base and select the face .
*Now,select the sketched line which need t be trimed as shown below .
* Sketch for normalcutout :
* Model Before normalcutout :
* Model After normalcutout :
* Performing rebend :
Rebend : The process that restores the unbend feature to its previous position ,along with any features added after the unbend feature .
* From bend tool bar,select rebend .
*Now,select the surface which need to be performed rebend and click apply as shown beow .
* Model before performing rebend :
* Model after performing rebend :
* Performing of break corner:
Break corner: This rounds or champers the sharp edge of tab or a flange .
* From corner tab select break corner .
*select the sharpe edge of the tab and give 12mm and click apply the as shown below
* Model before performing of break corner :
* Model After performing of break corner :
* Performing Of Unbend again :
Unbend : The process that flattens the bend and the material adjecent to the bend .
* From tool bar select unbend and select the a face which is to be represented .
*Furthermore,select the face which need to flatten and click apply as shown below .
* Model before performing unbend:
* Model after performing unbend:
* Performing of Holes :
* select sketch from construction tool bar .
* Draw a Ellipse with 24mm*30mm,with given dimension and click finish.
*And draw a rectangle too with dimension of 11mm*8mm as shown below .
*Sketch according to the required dimension as shown below .
* Model before sketching :
* Model after sketching :
* Performing of Normal cutout :
Normal cutout: The method that cuts material by projrctiona sketch onto the model and then cutting perpendiculr to the faces intersected by the projection.
* Select normalcutout from base and select the face .
*Now,select the sketched line which need t be trimed as shown below .
* Model Before normalcutout :
* Model After normalcutout :
* Isometric view :
* Front view :
* Right side view :
* Conclusion : From above it is observed that a sheet metal can be generated with required gusset holes and cutout .
