Multi Stage Deep Drawing

[Anonymous]

Hi guys,

    I am looking for an option or an add-on in inventor which helps me create Multi Stage Deep Drawn components.

It'll be really helpful if this tool can also help me analyse the same components.

I have shared a link with respect to what i am looking for, kindly advise on what can be done.

P.S :- The video link is only for a reference.

Kind regards.

I worked as a Manufacturing engineer when I got out of college for a company that made gas cylinders.  We had several presses that did deep draws in stages like you show. Had to anneal the material between draws because of work-hardening.

This is non-linear deformation, which Inventor will not do. Does anyone know if Fusion 360 might do it?  Will probably need a FEA program to do an analysis on the part.

I think you are looking for an iPart..

https://knowledge.autodesk.com/support/inventor-products/learn-explore/caas/CloudHelp/cloudhelp/2014...

you can create each stage as a member of the ipart and then document them on different views, same sheet or not.

here's an older post on this.

There is no option/addin for Inventor that does that as far as I know..

But you might want to be more specific and state what specifically you want to analyse,etc..

If you just want to make a pretty video like you show then Inventor can do that..

But I suspect you actually want to analyse and get information on blanks/stresses,etc.....

If so you might want to look into programs like autoform, abaqus.. Not sure if Autodesk simulation can do that (probably but not tailored specifically for deep drawing functions)..

You may want to contact these guys and see if they are still developing for Inventor..

But a non-native step file could be used in any software vs being an addin that works with native Inventor files..

You really need to define your needs better so a better answer or direction can be given

Hi Mohan,

I think Adrian is right. The closest workflow to achieve this is to use iPart. iPart generally is to create library components which can be reused extensively with well specified dimensions captured on a table. Each member represents a different part with a unique part number. However, it can also be leveraged to do what you are looking for to certain degree. Essentially, you will need to model the part as in the final stage. Then each member, certain features are suppressed accordingly.

Another option is using nested derive workflow. You start out a base part. Then you derive it as a different part for next stage. You add some more features representing the stage. You keep doing it until the last stage.

Either workflow lead to multiple ipt files. You will be able to document the stage individually. We have heard comments that multiple part files representing multiple stages of the same part is too cumbersome and creates file management issues. We are aware of that and we are investigating how to improve it. Ideally, we only need one ipt file. Each stage can be triggered or switched at any given moment without affecting other stages.

Many thanks!

I currently design high pressure parts for water blasting and work at a machine shop. This is exactly how I handle our machining processes, (with iparts).

What I do is model the part and then work with the machinist to determine which machining porcess will require a mill or a Lathe set-up. the drawing for the part then lists out the "stages" in which the part is created.

For example, the rough Bar will get turned down on the Lathe, the next stage may be a mill operation, then back to the lather for cleanup or threading. In this case I would have my part made with 3 "stage" options, each option would be an ipart instance.
