- Okay, we're standing in front a press brake.
This is a six foot machine
and we're gonna get set up to do a bend.
We've got a couple of bending dies,
this is a lower die, this is an upper die.
And these go together in the machine
so they actually do the bend.
We actually have a larger one already set up
in the machine here and we're ready to bend some parts.
Alright, so I'm gonna change the flange dimension here.
So I'm gonna go into the cycle start,
click on the flange dimension,
click on 1.5, enter, and we're ready to bend.
To design efficiently, try to keep your bends the same
and with matching flange links
to avoid having to set up
multiple sets of tooling with different back gages.
Also consider the bend radius.
The standard tools come in 0.30, 0.60, 0.90, eighth inch,
quarter inch, three eighths inch, et cetera.
Try to design using these standard tools
to avoid custom tooling
that can add cost and lead time to your parts.
You can see we can stage multiple bends,
one after another, on a part.
So I can do the first bend with the same tool,
flip that same part around and do a series of bends,
all using the same tooling,
with just different back gage links.
Many times in Solidworks, you can design parts
that are very hard to build in the real world.
For example, if you see the lower die in the video,
the flange needs to extend past the center
of the top die and touch the top
of the V groove on the back section of the tool.
As a general rule of thumb,
we wanna have a minimum flange length
of four times the material thickness.
To switch our brake tooling,
what we need to do is use an alan wrench,
release the tool, and come in with the bottom die,
go ahead and release the lower tool,
swap that out, and we can grab our next set of tooling.
To set up a brake, what we need to do
is select the correct sized tooling for the job.
First we need to add the lower die in
and then tighten it down.
Secondly, we bring in the upper die
and then bring down the press brake
to put a little pressure on the upper die
while we tighten it down.
Once it's ready to go, we then adjust our back gage
and our bend angle to make the part.
There are many different types of tools
we can use in press brake dies.
Here is an example of just a few.
Many times when designing in Solidworks, we can design parts
that are really hard to build in the real world.
For instance, if you make a hole too close to a bend,
the material can pull into the bend region
and cause a part to deform outside of what we'd expect.
You can see in these videos here, we have some holes
that have been pulled out of round
and the material has been pulled into that bend region.
A part like this, you can see we have
a really thin section on the top,
that even though it was formed,
you can see it actually warped
a little bit when it was being processed.
In the case of this part here, you can see the material
actually deforms a little bit because the bend relief
is not adequate to allow the bend to fully complete.
Keep these things in mind when you're designing parts,
that you need to make sure you have adequate bend relief,
you keep your holes and features far enough away
from the bend regions so you don't have any pulled material,
and if you're working with any hardware,
the hardware has minimum distance from the edge
so that you don't have holes
that have pulled out of round or deformed.
In this part here you can see that the bend relief
did not fully extend past the bend area.
The bend affected region
and we have some pulling of the material.
Also, think about how your part will be processed.
A part like this could be extremely hard to manufacture
because you have a flange that actually interferes
with the interior flange when the part was built.
It just makes things much harder,
it's gonna drive up cost and lead time on your part.
