deform 3d - settling of matrice movement (cold forming)

[rory_the_king]

Good morning, everyone.
I open a new thread to discuss a simulation point through deform-3d of a molding station.
after having created and imported the main parts of the station to study, comes the point where it is necessary to set the movements carried out by the matrices.
is to assign the following parameters (treatment of a translational motion case):
- type (speed, mechanical press, force, hydraulic press, millet, sliding matrices, screw press)
- direction (x, y e/o z)
- definition (however, function of time, function of the race, proportional to a speed of another object).
had it for cold printers (5 or 6 stations) what do you recommend?
Greetings to everyone.

...if I understand well you don't know the cinematics of the car you're going to print on? ...

I have the relative movements of the hammer and the matrix, but I have no idea of the speed and powers in play!
Does anyone have data and/or anything?
Hi.

I hope it can help you:

a machine that cuts to max 20mm of wire (600mpa) has a stamping force of about 2200kn, a 75kw motor and a maximum speed of 160 strokes/min (plate data of a press of my knowledge)

So the first aspect that I think should be evaluated is diameter and resistance of the starting wire.

Hi.

Then:
- the power in play gets it at the end of the simulation as it is function of the molding force
- if you work with a press (and I think it's your case) you have to distinguish with what kind of press work.
- if you choose to work with an eccentric press, the data can be found more or less in any catalog of eccentric presses: to the eye!
1 not all eccentric presses are equal!
2 at the simulation level will ask you some extra data that should be taken in operation if the press is born to print hot or cold, if it is a press to drool or one to work sheet.
- if you choose to work with a ginormous press (or multi-link) the problem is complicated because the data you need to simulate the cinematics is only found on the machine manual itself.
- if you choose to work with a hydraulic press the problem of complicates again because the speed range is wide, so they intervene technological reflections for the choice of working speed.

If you have to make a simulation that has no practical purpose with some extra scoops on the process I can tell you some presses with the relative parameters that serve for simulation (using forge I think the parameters eventually turn and turn are always those). .

I hope to help you... :biggrin:
