Ubatoid Posted May 2, 2010 Share Posted May 2, 2010 I am having a a little trouble drawing up some sheetmetal items in SW 2010. Basicly what I'm after is a 1mm sheet with a 30mm dutch fold (over and flat, hem) all round and then the 30mm edge is then folded again with a 9mm flange and then again at 18mm to produce a tray. What i cant seem to do if create a fold after Ive have created the hem edge. Anyone got any tips or ideas ? Quote Link to comment Share on other sites More sharing options...

Ubatoid Posted May 2, 2010 Author Share Posted May 2, 2010 This is a quick sketch of what I am trying to achieve... I have tried starting with a base flange and then adding a HEM, and then adding a sketch bend, but this does not fold up both thickneses. Also tried starting with a base flange, adding a edge flange then another edge flange and then a hem but to no avail... Quote Link to comment Share on other sites More sharing options...
shift1313 Posted May 2, 2010 Share Posted May 2, 2010 are you only doing this on two sides? whats wrong with what you have there? Quote Link to comment Share on other sites More sharing options...
Ubatoid Posted May 2, 2010 Author Share Posted May 2, 2010 This will form a four sided tray with the corners notched to accept a square leg. What I have drawn was a simple extrude from a sketch, not a sheetmetal part. I need to be able to get the blank size by unfolding the sheetmetal.

shift1313 Posted May 2, 2010 Share Posted May 2, 2010 you can convert it to sheet metal. in sheet metal after you have drawn your base, try using the miter command. Select the edge you want and it will start a sketch based on that edge and its end point. Draw what you have there. Sorry i dont have SW in front of me so i cant draw an example for you.

Ubatoid Posted May 2, 2010 Author Share Posted May 2, 2010 That doesnt seem to work, keep getting errors. This is what I have drawn.. Quote Link to comment Share on other sites More sharing options...
shift1313 Posted May 2, 2010 Share Posted May 2, 2010 for miter you only have to draw a single line path i believe. That sketch would produce problems since the inside and outside radii are not concentric as well. Let me try to remote desktop my work computer and see if i can get something to work.

shift1313 Posted May 2, 2010 Share Posted May 2, 2010 alright i was able to get my remote desktop to work and get on my work comp but it was terribly slow so i just did this quick example. You can see the sketch lines(no bends/fillets) which shows the outside edge of the miter flange. So all you need to do is draw straight lines where you want the outside edge. The bend radius and all the other settings will be taken care of by your sheet metal defaults or in the miter flange properties. Quote Link to comment Share on other sites More sharing options...
Ubatoid Posted May 2, 2010 Author Share Posted May 2, 2010 Aaaahhh, that is some nice work. I will go and have play right now. Many thanks for the tips. Quote Link to comment Share on other sites More sharing options...

JD Mather Posted May 3, 2010 Share Posted May 3, 2010 dutch fold (over and flat, hem) all round Is something like this what you are after (half split away). Quote Link to comment Share on other sites More sharing options...
JD Mather Posted May 3, 2010 Share Posted May 3, 2010 Hey Shift, what would be the most efficient technique of reproducing attached in SolidWorks? (pull down the EOP) Double Dutch.zip Quote Link to comment Share on other sites More sharing options...
shift1313 Posted May 3, 2010 Share Posted May 3, 2010 Hey Shift, what would be the most efficient technique of reproducing attached in SolidWorks? (pull down the EOP) I would still use a miter flange. You can select all 4 edges at once and it will make that part. Its the same as a contour flange in inventor. I am curious though, is there a reason you split the solid instead of using Section on the Inspect tab? Quote Link to comment Share on other sites More sharing options...
Ubatoid Posted May 4, 2010 Author Share Posted May 4, 2010 Thats the badger. I had a play with the mitre flange technique but was unable to get the clearance between the flanges small enough. What JD has drawn looks interesting though. How did you produce it, I cant open the attached IPT file, my Solidworks says I have the wrong inventor type.

JD Mather Posted May 4, 2010 Share Posted May 4, 2010 Here is a STEP file of my solution. Only took about 5 minutes in Inventor. I'm still trying to figure out how to get it in SolidWorks without a lot of work. Double Dutch.zip Quote Link to comment Share on other sites More sharing options...

What JD has drawn looks interesting though. How did you produce it, I cant open the attached IPT file, my Solidworks says I have the wrong inventor type. It works just fine for me. I set my gap down to .01" with no issue. What gap are you trying to achieve? You can use the closed corners to tighten up the edges if needed. I uploaded the one i just made. drag the end of part line down after you unzip the file. dutchfold.zip Quote Link to comment Share on other sites More sharing options...
JD Mather Posted May 4, 2010 Share Posted May 4, 2010 Well I plaed a bit more and got it but matt beat me to the solution. Here is mine, now I'll go take a look at Matt's. DoubleDutch.zip Quote Link to comment Share on other sites More sharing options...
shift1313 Posted May 4, 2010 Share Posted May 4, 2010 shame on you JD sketch fillets and an under defined sketch:) Quote Link to comment Share on other sites More sharing options...
Ubatoid Posted May 4, 2010 Author Share Posted May 4, 2010 Thanks for that Mat. I shall have a proper look again at my effort, and see where I am going wrong. Last time I worked in inches, I was working in a shipyard that is now a development of exclusive flats? Thanks also JD, Ive only been using SW for 4 years now, so I guess I have a long way to go yet.
