PEM fasteners to sheetmetal

186 Views, 11 Replies
11-13-2002 01:35 AM
I as well as many others I'm sure, regularly use PEM clinch fasteners in
sheetetal parts.
We typically specify the fasteners as part of the sheetmetal piece and the
sheetmetal house supplies the finished part.
Calling out the hole and verbally specifying 'project this side' is a rather
risky scheme....

Other than make assemblies to incorporate these fasteners, are there any
other methods to accomplish this.

Thanks,

Paul

Paul,
We make assemblies of our parts with PEM's in them, and then make the .IDW
based on the .IAM. There is no guessing as to which direction the PEM will
go. Why wouldn't you want to use this method?

I've tried deriving the assy into a single part, but I prefer the assy
method. I get an accurate parts count, can easily balloon each fastener
type (I almost always have more than one PEM type) and the drawing shows
exactly what I want the vendor to produce. I don't do flat patterns and my
sheet metal house prefers it that way.

Same here. Every part is a assembly .... I still callout the direction even though in
most cases it is obvious.

I used to do it that way too.
Then came Inventor.................Now I make assemblies.

Mike,
I suppose it's just a follow over of doing it this way for too many years
(w/pencil!)
Always thought of the parts as essentially an inseparable assy, kind of like
a weldment.
PEM callouts were via a field note and we didn't show a parts list.
So what you do is create a IDW for the sheetmetal part to fab it with, then
an IAM based on the fab detail, install and show/callout PEM's with an on
sheet Parts List?
Then the IAM is used and shows on the next assembly...

My wife accuses me of being extremely resistant to change.... guess I'll
have to show Her....!!

Thanks...

Not sure I follow what you are saying below

I make a SM part ... called 0247-01.ipt
then make a Assembly with 0247-01.ipt and all the PEM parts and call it 0247-01.iam
Make a IDW of 0247-01.iam showing all the PEMS in every view. (Except Flat if I show one)
Bom and balloon all the parts. Add direction callouts if needed.

Top assembly only references the iam files such as 0247-01.iam.

I may be, and probably am, missing a capability in IV6... At what point do
you create an IDW of the IPT (for fabrication), or is it possible to show
all the dimensions at the IAM level?
I create a seperate numbered detail dwg for fab, then use it in a new
numbered assy dwg.
Using your numbers ie;

SM part 0247-01.ipt
SM dwg 0247-01.idw
then to add PEM's, press pins etc;
SM Assy 0248-01.iam (uses 0247-01and other parts)
SM Assy dwg 0248-01.idw (BOM and baloon callouts, directions etc.)

The above scenario allows me to stock (if I desire for spares) seperate bare
sheetmetal (sans PEM's, pins etc.) and also finished parts (incl. PEM's,
pins etc.

I use PartsNow which is wonderful for getting most all of the ancillary
parts that we typically use.
Then of course my next issue is to take these nice parts descriptive names
and assigning them part numbers for purchased part specs. and inventory.

I'm thinking of the logistics of assigning 'part numbers' for identification
and inventory.
Beginning to think I'm doing what I see so many others do....use today's
technology to automate the old manual methods...hmmmm maybe time for an
afternoon of pondering..

Yes it is possible......no different than at the IPT level.

Ok I see the issue a little better. I never stock SM parts without the parts pressed in.
Couldn't you just call it out on the PO? SM part no pems installed?

(BTW in my scenario, the 0247 is the project # and every part in that project starts with
that number. I guess you would end up with every part being 2 different
parts.....0247-01... plain SM part. 0247-02 SM with pems.

Good luck with it... sounds like your needs in this area are a little more involved than
mine. 8^)

in a hurry one day...all i did was add a feature(s) on the sheet metal face (a circular extrude to whatever the diameter and height of the pem i was using) then on top of that, i just drilled a threaded hole. this allowed me to still have an ipt with what 'looked' like a pem, and plus, i already had the part in a hefty assy, so this was easiest/quickest. -Joe
