Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

TITLE -  BOX ASSEMBLY

AIM- DESIGN SHEET METAL BOX ASSEMBLY USING NX-CAD IN SHEET METAL ENVIRONMENT 

INTRODUCTION

A MATERIAL HAVING THE THICKNESS RANGE BETWEEN (0.5 to 6)mm IS CALLED SHEET AND HERE WE ARE GOING TO DESIGN THE BOX USING ALL THE SHEET METAL OPERATIONS.

DESIGN FLOW CHART

• CREATE THE BASE OF BOX
• CREATING FLANGES AND HEM FLANGE
• ADDING FEATURES SUCH AS DIMPLES AND BEADS.
• CREATE THE LID FOR THE BOX
• CREATE THE HINGE FOR THE LID FOR OPENING AND CLOSING  PURPOSE.

STEP BY STEP PROCEDURE

CREATE THE TAB IN XY PLANE OF DIEMENSION (200*150)mm AS SHOWN BELOW.

     

CREATE THE FLANGE NORMAL  TO  XY PLANE THAT IS ALONG YZ PLANE

 

CREATE THE FLANGE ALONG XZ PLANE

     

WE HAVE TO FILL THE GAP SO WE ARE GOING TO USE CLOSE CORNER COMMAND

WE ARE NOW GOING TO JOIN THE OPPOSITE WALL BY HEMMING OPERATION FOR THIS FIRST WE NEED TO MAKE THE FLANGE WITH BEND RADIUS 0 AND LENGTH 0.02

  

ON THAT FLANGE CREATE ANOTHER FLANGE OF LENGTH 6.5mm

            

NOW WITH THE HELP OF HEM COMMAND WE CAN JOIN THE FLANGE

     

NOW MIRROR THE BODY USING MIRROR BODY COMMAND

   

CREATE THE DIMPLE OF X SHAPE AND MIRROR THIS FEATURE ON THE OPPOSITE SIDE OF THE WALL.

                           

CREATE THE DIMPLE ON THE BASE OF THE BOX

  

CREATE THE BEAD ON THE BASE OF THE BOX.

             

CREATE HEM ON THE EDGES 

                  

CREATE THE LID ON THE TOP OF BOX FOR THIS FIRST CREATE THE SKETCH ON THE EDGE

  

CREATE THE TAB USING THIS SKETCH

  

CREATE THE FLANGE FOR THE ROOF.

 

NOW CREATE THE TAB ON THE FACE OF THE VERTICAL WALL FOR THE HINGE 

 

AVOID THE SHARP EDGE USING BREAK CORNER COMMAND.

 

CREATE THE FLANGE AT 45 DEG WITH THE VERTICAL

CREATE ANOTHER FLANGE AT 40 DEG OPPOSITE TO THE DIRECTION OF VERTICAL FLANGE

USE HEM COMMAND TO CREATE THE SHAPE OF THE HINGE

AGAIN UNBEND IT TO CREATE THE SKETCH OF RECTANGULAR SHAPE AND DO THE NORMAL CUT OUT.

 

FINALLY REBEND IT TO MAKE THE HINGE

 

MIRROR THE HINGE THAT WE MADE.

CREATE THE TAB ON THE LID OF THE BOX

  

NOW CREATE THE HINGE OF THE LID IN THE SAME MANNER WE DONE IT FOR THE BOX HINGE

  

  

NOTE-ADJUST THE FLANGE OF THE HINGE SO THAT IT CAN MATCH WITH THE DIEMENSION OF THE HINGE OF THE BOX.

CONCLUSION : WE DESIGN THE BOX ASSEMBLY COMPLETELY IN THE SHEET METAL ENVIRONMENT OF NX_CAD.
