hello to all are giuseppe
I need to make a competition piston... but I don't know how to start.
I explain better, a factory could make me pistons by following my profile and a design, but being self-taught in drawing in autocad (I am electrician and limit myself to design only apartments plants with electric symbols) I wanted to ask if any of you could help me in drawing in cad a piston with particular cuts and dimensions.
Thank you in advance.
Giuseppe
Thank you Marco who addressed me on this post
 
Tell me how I can help you more specifically, that is, do you need a structural dimensioning or just an executive board? Moreover, I prefer to draw in solid edge

:
 
Unfortunately I do not know solid edge....and the world of cad. I can send you an image of the pistons to be realized.
I thank you for your readiness and I ask you, where to best direct my question.
I also attached a design of a biella type h
I have removed the attachment, as per user's request

evening axiss
to realize your pistons in cad 3d is not a big problem indeed it is a lavor that you do in 5 minutes counted, only that having not at disposal particular data on the geometry you risk making a piston from competitions....lente. . .
In the sense that particular cuts affect the dynamics of combustion and should not be done randomly, it would take a minimum of experience :)
 
but this is a speech that concerns the whole structure of the piston
geometry is fundamental to optimize dynamic performance in general that are generated on the piston during its operation, and surely cannot be the result of the case or a drawing based on a photo; it is defined on the basis of extensive thermostructural analysis with finite elements and test at the counter. otherwise you just risk throwing away money.... .

question: but commercially nothing like that??? :confused:

Sorry.
but what pdf did you attach instead of the biella?

and then you really think you can build a piston (but any object) looking at a photo? ?
However that is already a commercial, if you want it the same you have nothing but to copy it (but to detect it "live", not through a photo).

greetings
Marco:smile:
 
I was wrong with the annex too! ! ! !
I know that commercially located....the problem is that the piston is currently mounted in the engine block.
my idea would have been to get out of this photograph, a type design, so as to quote it as size of thorn and section of elastic bands. I can't do this so precisely.
I apologize for the envoyed attachment....but sometimes the rush makes nonsense.

According to you axiss one should make a design of a fundamental component of an alternative motor so randomly? without any specification? ? ?

there was one here on cad3d that made the checks on the volume of the combustion chamber with a "prototype" of the foil-coated paper piston and a piece of cesso tube as cylinder :smile: . axiss to comparison imho is light years ahead

That sounds bad.

But it wasn't bad that piston. It was a little tender, all gritty and cranky, but it was not bad, especially seen outside the pipe of the toilet. There are still photos:biggrin:

Right, right. .
as a pin we had a suppository, and as seeger two pieces of wire to close the bags.... :cool:

(if the author hears me.... I'm joking! . )

if the author reads (but, ahinoi, I think he has eclipsed) will complete the piston according to your instructions, contact us:biggrin:
 
Come on, do the good, already the fact that he left a piston and did not try to get a turboprop at home. or to improve in the garage a rolls-royce merlin reading the magazine ... is a positive fact:-)

ah but we talk about the future diesel engine designer, the one with a paper piston, not of axiss:smile:

marcof you are a great.. .
But what happened to the road trip? Did he explode the prototype of 20 floors of softness?

probably during a paper piston seal test in the 80 pvc tube, he accidentally leaned on the sludge lever and the piston went. :smile:
