Tutorial 9: Sheet Metal Design

Introduction

Sheet metal is a commonly used material for the design of engineering systems. In this tutorial, you will learn to design sheet metal parts containing multiplewalls, bends, cuts, and holes. You will also learn how to create a flat pattern of the part.

Creating Base Shape

1. Start Pro/E Wildfire.. Select !"ile# $% !&ew#, and type the part name !E'ample(# in )e't *o'.+. a-e sure !Part# is selected from the )ype menu, and select !Sheetmetal# from the Sub$type menu. lic- !0# *utton.. Select the reate 2nattached E'truded Wall icon from the tool bar at the right of the screen, as shown in "igure (.1.

3. Select !ne Side# from the 4))5I*2)ES menu of the menu manager. )his will cause the part to be e'truded in one direction only.6. Select the "5&) plane as the s-etching plane.7. "lip the arrow if it is not facing away from you, and select !-ay# from the 8I5E)I& menu.9. Select !8efault# from the S0E) :IEW menu. Pro/E should now enter S-etcher mode.(. 8raw the profile shown in "igure (. and dimension it as shown. &otice that two of the radii ha;e dimensions of 3 while two ha;e dimensions of 1<.

)his is because some represent inner corners of the part while the others represent outer corners. 4lso note that you are not drawing a closedprofile, since the sheet metal is of constant thic-ness which you will define later.

1. Enter !3# into the te'tbo' on the dashboard to set the thic-ness of the sheet metal, and clic- the chec- button.1+. a-e sure SPE ) is set to !*lind# in the enu anager, and select !8one#.1. Enter !1<# into the te'tbo' on the dashboard to set the e'trusion depth, and clic- the chec- button.13. 4ll of the properties of the part should be shown in the window that reads "I5S) W4==> E'trude as shown in "igure (.+. If you need to change any

properties later, you will use this window. Select the -ay button in this window. You should see the part shown in "igure (..

Creating Additional Walls

1. Select the reate "lat Wall &o 5adius icon from the tool bar at the right of the screen, as shown in "igure (.3.

9. You will now add a datum point to help define the ne't wall. Select the 8atum Point icon from the tool bar at the right of the screen, as shown in"igure (.(.

(. Select the top right corner of the newly added wall, as shown in the figure, to define the datum point. Select !-ay# from the 8atum Point window.

11. Select !Part *end )bl# and then !8one/5eturn# from the menu manager. Select !ne Side# and then !8one#.1. Select the top edge of the newly created wall as the reference edge for the new wall, as shown in "igure (.11.

1+. Select !*y Point# from the SE)2P S0 P=4&E menu, and clic- on the datum point that you created in step (. 4 new datum plane will be automaticallycreated.

1. a-e sure the arrow is facing to the left, along the path of the edge you selected as a reference, and select !-ay# from the 8I5E)I& menu.13. 8raw the profile shown in "igure (.1. You will need to add a line along the edge of the pre;iously created wall as shown in the figure in order to

create the necessary radius.

16. 8elete the e'tra line you drew in the pre;ious step, and clic- the chec- mar- or select !8one#.17. Select !-ay# from the W4== ptions window. You should see the wall shown in "igure (.1+.

Adding Holes and Cuts

1. ?oles can be added to sheet metal parts in basically the same way as they are added in solid parts. Select !Insert# $% !?ole# from the menu bar at thetop of the screen.

. Select the top surface of one of the side flanges, shown in pin- in "igure (.1, as a reference for the hole.+. 8rag the reference handles and ad@ust their ;alues so that the hole is < from the side wall and +3 from the edge.. Set the radius of the hole to be 13, and cut the hole through the part.

3. 5epeat this process to create another hole +3 inches from the other side of the same flange. You should see two holes as shown in "igure (.13.

12



!"igure (.13#

6. 2se the menu manager operations Aas was described in )utorial 3B to mirror these two holes about the datum plane in the center of the part to createtwo holes on the opposite flange.

7. You will now create a cut in the part. You will start by unbending the part, since the cut will be through se;eral walls. Select the reate 2nbend iconfrom the tool bar at the right of the screen, as shown in "igure (.16.

9. Select !5egular# from the 2nbend ptions menu, and then select !8one#.(. Select the surface labeled 4 in "igure (.16 as the plane to remain fi'ed.1<. Select !2nbend Select# and then !8one# from the menu manager.11. Select Edge 1, hold down the control -ey, and select Edge as the edges to unbend.
