Sheet Metal Introduction

z Could draw part and extrude or revolve like in most of the projects to date.

z Sheet metal application more powerful.

z Parts have constant thickness.

z Do not need to mess with feature order to get part towork right.

z Old way very order dependent

z Easy to change sketch of previously created flange.

z Automatically takes care of bend allowances

K FactorsK Factors

z A si ngl e valu e whi ch c an be u sed t o rep resen t ho wsheet metal bends fold/unfold over a wide range of geometric parameters

z If your model is being used for manufacturing, setK<0.5

z If not it will not unfold correctly for most bendingscenarios.

z Use 0.42 or 0.33

Bend Type Common “K” facto

Large Radius Bend (radius 4

larger than stock) 0.5

Rotary Bender (like “Ready

bender”) 0.43

Vee Bend 0.42

90 Deg. Wipe - No Set Radius 0.38

90 Deg. Wipe Plus Set Radius 0.33

Bend AllowancesBend Allowance

z How much material isneeded between two panelsto accommodate a givenbend.

z Solidworks automaticallytakes this into account whencreating flat drawings from3D.

Solidworks Features

Base Flange – Creates sheet metal part

Edge – Adds a wall to an edge

Miter – Adds a series of flanges to an edge (or edges)

Hem – Curls the edge of a sheet metal piece

Sketched Bend – Adds a bend to a selected sketch

Closed corner – Extends the face of a sheet metal part



2

Solidworks Features (Cont’d)

Jog – Adds 2 bends from a sketched line

Break corner – cuts material from a face or edge

Unfold – unfolds bends in a sheet metal part

Fold – folds flattened bends in a sheet metal part

Flatten – shows the flattened pattern of a part

Rip – creates a gap between two edges

Sheet Metal Toolbox

Bottom

1) Add Sheet Metal Toolbar (Right

click; add Sheet Metal)2) Choose icon labeled Base

Flange

3) In the base flange window

select Front View

4) Create a rectangle withdimensions 9.89” and 18”

5) Exit sketch and the base flange6) Properties window will appear

on the left hand side of the

screen.

7) Under Sheet metal

parameters set T1 value to 0.1

inches

Bends:

1) Select the Edge Flange

icon

2) Select edge to be bent (18”

long edge)

3) Drag the bend direction up

4) Set D value under flangelength to 1 inch.

Cover

1) Create a “Base Flange”

drawing in the front plane.

2) Exit Sketch

3) Make to desired thickness.

End Pieces

z Create a “Base Flange”drawing in the front plane

z Exit sketch

z Both ends need to be edge

flanged

z Select “Edge Flange” from thetoolbar

z Selecting one edge at a time,

drag each arrow out (all in the

same direction.)

z Pull these edge flanges out 1”

z Repeat until the entire end

piece is flanged.

Sides

z Create a “Base Flange”drawing of the side of 18” X 6”.

z Exit sketch and on the lefthand side ensure that T1 is

again set to 0.1 inches

NOTE: All flange lengths from this

point on will be assumed as 1

inch unless otherwise stated.



3

Hinges

z Create a “Base Flange” drawing

in the front plane

z Exit sketch and ensure that T1

is set to 0.1 inches

z Create plane on top of rounded

part; draw 2 rectangles

z Cut Extrude rectangles through

all

z Extrude 4 bolt holes

HandleHandle Hinge

zCreate a “Base Flange” drawing inthe front plane

z Exit sketch and ensure that T1 is

set to 0.1 inches

z Extrude 2 bolt holes

Handle

z Circle extruded over path

Final Toolbox Design Hem Feature

z Select Hem icon

z Select edge to hem

z Choose hem outside or

inside

z Choose hem type (closed,

open (shown), teardrop or

rolled

zChoose distance to hem

Jog Bend

z When the feature bends in

one direction and quicklyagain turns in the other

z Create a line on the piece

you want bent

z Choose jog offset (distance

between the two bends),

position and angle

z Can keep original length of

piece being bent or can add

material as it bends.

Miter Flange

z Select Miter Flange icon

z Create sketch plane on

inside horizontal edge

z Draw shape of flange you

want to createz Click Propagate

z In Miter Parameters, under

Flange position, click Bend

Outside icon



4

Sketched Bend

z Select Sketched Bend icon

z Create a line drawing on the

surface you want to bend

z Exit sketch

z In the Property Manager

under Bend Parameters:

• Select the face with the

sketch below the bend linefor Fixed face

• Click Bend Outside

• Set Bend Angle to 90

• Select Use default radius.

Closed Corner

z Select Closed Corner

icon

z Select the edge of

the base flange as

shown for Faces to

Extend

z Choose corner

type: Butt (Shown),

overlap and under lap

Unfold / Fold

UNFOLD

z Select Unfold icon

z Select edge to unfold

z Select Plane to which the

edge unfolds

FOLD

z Select Fold icon

z Select edge to fold

z Select Plane to which the

edge folds perpendicular

Flat Patterns

z Largest advantage is the flat

patterns ability.

z Create items as you need

them in 3D

zWhen design is done,

collapse to a flat pattern.

z Keeps relationships true,

but creates a 2D drawing.

z Perfect for getting the flat

parts cut in large quantities.

Forming ToolsForming Tools

z Drag and drop from

design library.

z Maintain constantthickness.

z Only used for sheet

metal
