Sheet metal part

[drawingsCHR7R]

Good day to the Inventor community!

I have a bit of a block at the moment and I am struggling to model this part. (In the attached pics)

I have given this so many attempts and it just keeps failing. Could someone please assist me with modeling this!?

The biggest problems I am facing at the moment is the following:

1. The hole going through this bracket creates a notch at the top with apparently makes the bracket stronger thus I need to show it, all my attempts thus far have made it look like an extra part as opposed to being one with the rest of the bracket. ( i am so frustrated with this at the moment due to my lack of sheet metal knowledge)

2. This is also a huge problem I am having, if you look along the side of the bracket you will see what to me looks like fillet or folded edge, this wouldn't be too tough to deal with if it weren't for the fact that it goes over a rounded corner too!! I have no idea how to make that? 

That's about it. All the help will really be appreciated guys! Thanks a lot.

Kind regards

H. Joseph

take a look at the part!

Lol that looks great! Unfortunately it still doesn't have the notch at the top it almost looks like a seam of some sorts (but it isn't) . My superiors are adamant that the notch be in. Yours also seems to be missing the rounded edge?

Thanks for giving it a shot though!

What version of Inventor are you using?

Can you Attach the *.ipt file of your attempt to model the geometry here?

The part can easily be modeled, but not as a standard Sheet Metal part.

This is a formed part, not a brake-press bent part.

You might be able to get it to Unwrap in 2020 if you need a "flat pattern".

[drawingsCHR7R]

Of course. Find here attached said ipt. 

Initially I did do it as an ipt and then converted to sheet metal because this will in the end of the day be a pressed product.

I would really appreciate your assistance on this!

These are the two best attempts I could do. I am currently using Inventor 2020.

@JDMather 

before I forget I gave it another go today, I tried using contour flange to get the notch profile. Looks really good but not too sure how to go from here.

[JDMather]

Your sketches are not fully defined - not placed logically relative to the Origin Center Point.

I assume you have not had any classroom training in how to use the sketcher.

This might take a bit longer as we will have to cover the basics first.

Back in a bit...

@JDMather 

That is correct, I am self-taught with regards to Inventor. Most of what I know I figured out and was assisted by the autodesk forums.

Thank you! I await your response.

[JDMather]

I need a bit more information.

In this picture the "feet" look a bit wider than the "body".

Is that the case?  If yes, what is the width ??

Also, I need a picture from side indicated.

When taking these pictures - try to get as perpendicular to the faces of the part as possible.

Edit: Well that is just great, this morning I cannot embed images.

Hopefully the zip will work.

[drawingsCHR7R]

Yes the "feet" are a bit wider but this is only due to the fold on the side making everything else be smaller.

I currently don't have the sample anymore so this is the best i can do right now with regards to a side view. Thanks for the tip, will definitely keep it in mind when I take pictures again.

i have also attached the flat pattern that I was able to make. 

[drawingsCHR7R]

@JDMather 

Apologies, I forgot to add the side view that I have.

[JDMather]

Another tip - when taking photos - place a sheet of paper (I prefer orange or green) in the background.

@drawingsCHR7R 

The pdf file you attached does not match the part?

Are you attempting to model it as a simplified bent part (as in the pdf file) or are you attempting to model as a press formed part (the real world part shown in your photos)?

[drawingsCHR7R]

Sounds like a great tip. I'll definitely keep that in mind in the future.

No they are definitely the same part. The one I just converted to sheet metal and did a flat pattern and an isometric view hile in idw. The first one is before I took it to sheet metal. Apologies about this it was a while back when I did this, had multiple attempts with a different idea each time.

Where ou able to make the notch and rounded edges?

[drawingsCHR7R]

Hi there,

Just wanted to find out if you made any progress on the 'how-to-guide' for modeling that piece?

Thanks for all of your assistance thus far on this, it is greatly appreciated.

[JDMather]

This will probably take several weeks as I have my real work to get done first and also I am concerned that we need to cover basic sketching techniques first, or you would not be able to understand and adapt my modeling techniques.

[drawingsCHR7R]

No problem. I fully understand.

Thank you for your assistance on this, have a great day further.

[JDMather]

Start a new part file from scratch.

Sketch the 103 x 50 rectangle as shown.

Q1. What color is your rectangle?

Q2. What does it say in lower right corner of your screen (see image below)?

Attach your new *.ipt file here with only the rectangle for next step instruction.

[drawingsCHR7R]

@JDMather 

Find attached.

@JDMather 

Apologies, I didn't answer your questions.

Q1: Using a 2 point centre rectangle from point of origin my rectangle was black and I inserted your two dims.

Q2: It says fully constrained.

[JDMather]

From Step 1 - add a Coincident constraint between midpoint of bottom horizontal line of the rectangle and the projected Origin Center Point.
