cochlea in sheet metal

[Gilsephony]

I make a solid with helical protusion also because:

1: the cochleas are already made of all measures and with proportionate steps.
2: They compose themselves by metro as a cochlea already calandrated.
3: If you want to know how much development is, just do the auger with protusion and see the outer and inner lengths of edges. In this way you know the inner and outer diameters of the circles to be cut.

However the best solution is 1!

we've already made them. .
they use special macchi especially made for this...

this image of how I would like to get the cochlea.. .
obviously made with shetmetal not in part!!

What do you need to do it in sheetmetal that you can't develop? in any case from the room menu - switch to part and you will have all the commands available.

Hi.

In fact in sheetmetal does not develop, the only way is to do it as I indicated, or better yet to buy it already made

I tried to make a par, then to convert it to psm, but it does not develop (v19)... in reality however usually it is used a curved dish with appropriate machinery. . since I am of vice, I recommend you contact a company that directly produces the worms that you can then weld to the central tube. (There's one in two... I don't work for them, but they are the only ones in the area).

You can't develop that kind of sheet! !
As they say, they are made especially by machinery. development is calculated by those who make these products.

Hi.

Maybe he's one of these producers!!!!

in fact it takes appropriate machinery, as already explained above by me, when I worked for the food sector to make the screws we sold out the staggered disks, how to build a spring and then with a special calandra came out the coclea, because there was the need to make them in "house" and not to buy them already made.
