Sheet metal gusset

wancrum · ‎04-14-2017

Hi there,

I am trying to model a sheet metal bracket that will be used to attach parts at 90°. I don't understand how to add a gusset for strength in the bends. I found the post referencing cbliss's website but when I try to open the downloaded file it gives me an error. Could someone please point me in the right direction for how I should go about this. I believe I can create a punch for the three ribs in the center but I am just unsure of how to go about creating the gussets on the bends. Thank you for any help with this.

Can you post screen shot of the error that you are seeing?

Here are the two messages that pop up.

I don't think you will be able to get a flat pattern from the fully modeled part, but you should be able to use a simplified model without the stamped features and another model with the stamped features.

If you attach your file here modeled best you can - I will show you how I would do the gussets and center pressed feature.

Here is what I have so far. I attempted to create a rib and shell it out in an example. I created the bracket as a standard part in the second attachment but was unable to recreate the shell from the first. Last is an assembly of the bracket being used. We would modify the bracket or our part to correct hole spacing. I have it where it fits to the bracket right now. I am going to go back to try and create it as a sheet metal part. Thank you for your help.

Is something like this what you are after?

Have you installed all Service Packs and Updates for your version of Inventor?

Yes that is what I am trying to create. I was able to recreate what you did. Thank you for your help. I didn't know about the draft tool. I tried to recreate the sheet metal version gusset with both a revolve and extrusion but wasn't able to get the shell to appear correctly. I understand if the sheet metal is flattened it wouldn't show the gusset anymore so I tried the above after creating the flanges and unfolding them. If we wanted to make a version of this part, we would send the manufacturer two drawings of it- one with gussets and punches like what you modeled and another sheet metal part showing the blank unfolded. I'm thinking of how I would ask someone to make this, and that is what I would tell them. They would use both drawings to recreate the needed features?

Our version of Inventor should be up to date. I haven't seen any messages saying otherwise.

Compare the iProperties of your file vs the file that I attached.

Would a derived part work for you?

You can have the sheetmetal part without the gusset in the main part. It would contain all the regular bends and sheetmetal features required to create the flat pattern.

In the derived part, you can add additional manufacturing steps like the gussets, or maybe model the corners closed simulating a weldment.

Let me know what you think about that approach.

Kind regards,

Gerald

Do you still have trouble with this? I have just uploaded a video to demonstrate my solution. That is an Inventor addin. Hopefully it's still able to help you and everyone else.

Hi @S_May

Sorry for not attaching the file. In fact, the addin has been uploaded on app store, and waiting for approval.

I temporarily attached it in this reply. If you are interest in it, or you have any comments, please don't hesitate to let me know. It will be much appreciated.
