i need a die made to shape tubing with my shop press, anyone that does CNC machining please post here or send me a pm, thanks.

 

A die like what I visualize you need does not require a CNC and can be run inexpensively on a lathe.

Im not trying to sound smartass-like.

 

the shape is rectangular and tapered.

i didn't take it as a smart-*** comment , i should have mentioned the shape in my first post.

 

Just curious what are you using it for? collectors id guess?

 

yup, t4 divided.

 

If you have a print, drop me a line..

 

yeah, a cad file would definitely be a good start. or atleast a sketch.

 

my cad drawing skills are limited but ill give it a shot and post a screen-shot and here.

 

Waiting for a drawing or a very accurate description

Am I assuming you're trying to neck the pipe down? You won't really be able to add a taper to any pipe with a shop press simply with a tapered die - it will crush the pipe out and pinch it at the tapered end. The typical way to do is is the spin the pipe on a special lathe, then hammer it down gradually with a special die thats internal and external. Of course this assumes you'll use it as I'm thinking, so no offense intended

 

I'm not trying to taper the pipe just the die.

 

random idea on a way to flare the pipe to match the flange.

basically the wedge block bolts to the flange. the die is slightly under size of the flange hole when completely expanded, and is machined small enough to fit inside the pipe completely collapsed. a couple bolts into each die block go through guide slots in the wedge block. then the wedge, which is tapered to match the die blocks, is bolted loosely to the wedge block with a large bolt. cherry the pipe, slip the flange assembly on the end, and hit it with an impact. should be able to stretch the pipe to match the flange.

any one think it will work? There is definitely an easier way, but I can't think of it right now.

 

I assume you want something like this... (ms paint ftw)

 

you got it earnie

i cant get the program to taper anymore than 92 degrees with the rounded corners but like you said the top needs to be just a bit smaller than the schedule 10 I.D.

 

is this what you are after?

 

Rosko - thanks for helping, the shape im looking for is like your top picture but the top the same shape as the bottom and just a bit smaller than 2" measured diagonally.

i think that keeping the rectangular shape from the start would require less pressure since the corners take up less surface area then the circular shape.

what do the dimensions of the flange side need to be? how tall does the punch need to be?
