Description

Measurements of machine

A

We're here with terry we're going to take some measurements of the coil winder. This is this: is the hydraulic power unit that runs it. This is the coil winder itself.

A

It's got a hydraulic motor here coupled through a chain drive and that what is that 80 chain or 100 chain? I.

B

Think it's 100.

A

That's 100 chain right there, that's pretty thick, two bearings and okay. So let's get the measurements.

B

For the structure bearings because we've got another bearing up here.

A

Okay, yeah there's a third one. Third,.

B

One up there and then that and then you have the the drive hub here, which is keyed to this inch and a half shaft.

B

And then the shaft is long because we actually put. We have a large cone that we had made.

A

B

And and it bolt and it fixes onto the frame.

A

B

We can actually make conical shaped coils.

A

Would you extend this even higher for higher larger boilers.

B

Good but then you're, then you're kind of limited you'd have to use something heavier than this because, as you start winding up, the pressures out here get.

A

B

A

B

You get a lot of flex, okay,.

A

So, let's just measure the whole thing. So, let's start with the cube.

B

So we've got- and this is eighth.

A

Inch angle, one and a half.

B

Yeah, that's that's what it is. It looks like it's our base. First measurement, our.

A

B

Is 22 by probably 22.

A

They're about yep 22 by 22.

B

And then, of course, your height and your legs, and all that is that's that's up to you.

A

Okay, let's get to the just to the frame where it is there without the legs. Okay, so.

B

So we're at looks like yeah.

A

B

A

And then for this this member here, how far down is that just just let's just get the exact things? Okay, so we've got like seven and five-eighths down for this member and measure that that's what is that two inches? That's a two inch by one eighth angle, and this one is what one and a half that's only one and a half yeah one. No that's! Actually one and three quarter.

B

A

Angle by one eighth, okay,.

B

A

Do this we have a half inch plate here, holding your.

B

Main bearing uh-huh.

A

How wide is the plate.

B

A

Inch plate the main bearing and that's uh the shaft is what inch and a half inch and a half shaft. And it's just a.

B

Shaft that we bought out of the master car- okay, that's.

A

Cold rolled uh yeah, okay, so we've.

B

Got six inches another six inch plank for the bottom, bearing.

A

Is that three sixteenths.

B

Yeah, probably probably or is it it's.

A

Not a quarter and.

B

It's not it's probably 316.

A

316 is played at the ball.

B

Usually index 3 is.

A

You know okay and the legs now. So what are those that's? A pipe they're just.

B

Yeah they're, probably.

A

Just one height eight inches high.

B

uh With uh adjusters welded into the bottom of them,.

A

Uh-Huh leg, adjuster system.

B

A

So it's a nut welded in and then you'd put the screw in.

B

A

B

Expand that on that, and then these I just put on there, so we can move it around with the pallet jack.

A

Okay, okay, so let's see, let's do the motor mounting like the way you have it right now. Okay, so you've got a platform, six inch wide yep and that's what is that quarter yeah. It looks like cold rolled six inches yeah platform, so this is another one and another one and a half inch angle.

A

B

One two inch angle.

A

Here supporting that and a spacer metal spacer between that and this diamond plate, yeah.

B

There's uh just measurements for bracing, so.

A

B

Four and a quarter altitude of four and a quarter and a base of ten- and I don't have my glasses on so it's.

A

Ten and a half down there.

B

Uh-Huh so the same thing with all sides, both.

A

Sides yep and then a little reinforcement gusset there like four quarters. That's a quarter inch plate.

B

By four by.

B

Five: five: five and a quarter and.

A

This distance is four: is that yeah.

B

That's four inch gusset.

A

And then the verticals here are a quarter quarter by six quarter by six plates.

B

It's probably all it was made out of stuff that you can just buy off the shelf. Yeah.

A

And this is a right here: we have a 30 gear, reducer, it says input, horsepower is 1.48, but the reducing ratio is 30.

A

and then this hydraulic little hydraulic motor dh-361512.

A

What is that danfoss made in denmark hydraulic motor, okay, okay? So let's go to the now the main parts of how the tubing works here. So can you explain the function? Basically, terry? Okay,.

B

um What this is um it's a it's a clamp for your tube okay, because you need to have tension on that as you pull it through.

A

B

The pipe kinks and bends and and you get on uniform end result, so you so you so you this clamps onto your pipe I'll shoot the.

A

B

Just load it in yeah.

A

We're all right, try that we're.

B

All ready to bend one here, I will tell you later: we have, to put a 45 degree, bend on this in order for it to draw through, and we do that with that bench bender over there. Let's look at the bench.

A

A

Is this a standard off-shelf part, or did you yeah you.

B

Can buy those at harbor freight.

A

Harbor freight pipe bender.

B

Yeah, it's just a bench bench bender.

A

B

These are made to just bend flat stock and wire. We made these dies on the lathe so that we could bend the pipe.

A

Did you use a grinding grinder attachment no.

B

Just how did you regular carbide bit okay uh performed into whatever diameter we needed? Oh.

A

So you formed what we needed, so you made your little bit the round. You basically profiled the bit to get this done yeah. So the bit was like that big. It's like.

B

It was only half.

A

Oh and you did one-sided.

B

One side at a time.

A

B

A

Is that is that.

B

Just uh and then I have two different pipe sizes: there there's uh eighth inch and half, and then this has uh 3 8, 3 8 and a quarter in.

A

The other set okay and that's just a chunk of cold rolled steel, yup, excellent.

A

And this other.

B

Yeah we have two different size dies and they're interchangeable. You can put one in here and have a larger, larger radius band.

A

Which one do you use for the one half inch.

B

Well, I we use the small radius to make our initial bend. It just depends on what application you're using them for.

A

What what is the initial dies that came in? What are the initial guys that came with this uh-huh.

B

And they're, bending for bending flat stock.

A

Uh-Huh and how many dice did this come with like like five or something.

B

Or like yeah whole set five sets one.

A

B

Four: five: six, seven eight four sets and then there's also this for bending uh 90 degree bends.

A

That came with the.

B

Comes with the bender okay, and it also comes with instructions but they're kind of vague, so uh-huh.

A

And this this is what it was there initially yeah. This helps.

B

This helps you hold your whatever your work piece is tight against this axis.

A

Okay, so that's the pipe bender.
