MAking crimp plate using sheet metal

I need to create the crimp plate in inventor to give my shop the measurements before the crimping process for material and also give them measurements to complete the crimping process. I figured I could use the sheet metal process, but I need a little help in doing so. I'm trying to find an easier way than going back to Autocad and p-line everything.crimp pl.jpg

This one is trivialy easy.
What version of Inventor are you using?

Attach your ipt file here.

Version 12? or do you really mean 2012?

If you don't have a file, what is the picture?

Is this formed in a press brake?

If so what is the radius of the forming die?

What is the k-factor for that machine/thickness of material? You can find that out by taking a piece of the same material/same die setup and then measure its flat length. Then form it 90 degrees and measure the length of each resulting flange.

I can plug the dimensions into the program I have to figure out the k-factor if you can get the part formed..

(see attached image for the dimensions I need)

Examine the part that I posted.  You are doing too much work.

I also have a question, once i place my crimps the second crimp measurement is off and the overall length also. Can you give any insight on how to fix this. Do i change the unfold rule or the bend radius?

Are you also running Inventor 2012?

Attach your *.ipt file here and end all doubt.

Using 2017, if it helps the second bend show be 1" bigger.

Then your "k factor" is not correct for your press brake die and process (air bending/bottoming,etc..)

You need to edit the "unfold rule" and enter in a proper k factor to achieve the correct flat length.. 

You currently are using "4" V-Crimp Mild Steel Kfactor" which shows as 0.. It should be closer to .5

I have one other concern, we are using a special die that forms these part in one hit, but as you can see it come up for three hits at each v-crimp. How can i change it to come up with the correct information.

Well.. Thats up to you.. The "bend notes" functionality in Inventor is intended for individual single bends.

Adapt to what works for you.. Either don't show the bend notes.. Or only put a bend note for the single center line and edit it to make sense..

Or just use a leader or whatever.. 

 

Frankly I find it "goofy" that you have 47.4642 degrees,etc... anyways.. no one goes to that precision on a bend angle..

Why not 45 deg anyways? Whats the actual angle of the custom die..
