You can set the 3mm sheet on an electric cooktop for a few minutes. Move it around so the heat is distributed evenly. Drop the sheet on the floor. It will not ring like a cold piece of aluminum. It will make a sound like a piece of oak being dropped on the floor. It will form and roll through the roller with ease. Aluminum will after heating will be workable for a few minutes. It should be long enough for your roller. I press parts in a 5 ton press using the same process. Old ziplock bags between the parts in the press help the aluminum go where it's needed when forming parts. Have a great day.

Andy Great Job. I want to inform you about something else that will help you. On the adjustment roller you should mill a straight line from end to end on that one Roller about 1/8" deep. What the groove does is when you start to roll a piece of metal the groove on the top roller aligns your sheet. The groove into the top roller will align the metal so the ends will be square or straight with each other. If you roll thicker metal it helps with the circle alignment when completed. I have rolled a lot of metal in my life from 14 gauge metal to 1 1/8" Metal. So the line on the groove helps a lot. I just wanted to inform you. Once the Metal I tightened between the first two end feed rollers and straight with the groove the metal after rolling will be straight and inline. It helps a lot with thicker metal. Great Job. I love your Craftsman skill.

Very cool project! I looked at the math behind bending a plate, and if you increase the thickness by a factor of 3 and at the same time decrease the length by the same factor, the force required to bend the plate becomes three times larger. The formula for the bending resistance (W) is the following: W=(1/6)*w*h^2 , where w is the width and h is the heigth. The thing to note is that the heigth is squared. I hope it makes sense.

Dav Andy It looks good what you have made, really nice thumbs up all ten.

That would be a good way to do it if a larger range of adjustment was needed. The moving pinch roller could move in an arc centred on one of the idler gears instead of in a straight line, then the mesh would remain constant.

Brilliant!

Back in the early 70's I worked on the maintenance at Manganese and Bronze at their Ipswich works, all we made was sintered bearings, I was always told that they were intended for light load applications because under heavy load they crush down, I wonder what your experience will be.

@AndysMachines

Жыл бұрын

That's interesting. I don't have a great deal of experience with sintered bearings but I tend to use them in low speed applications where there's not much space (radially) for a roller bearing, such as this. I've found them to be able to handle higher loads than a similarly sized ball bearing, but perhaps a needle roller bearing would be better. I also like to turn bronze bushings from solid bar for this type of thing as they can be easily made in any size, but the cost of the material can be more than buying a sintered bearing if it's a standard size.

Excelent !!!

I did build the guides with some play so the rollers can be adjusted to a slight angle for rolling cones/funnels. I haven't tried this yet though. It seems to roll fairly parallel just adjusting the rollers by eye, flipping the material round each pass probably helps with this.

Nice project. Did you consider replacing the gears with a Schmidt coupling? A Schmidt coupling can transmit the rotation over a wide range of different spacings between the rollers and is pretty easy to make compared to involute gears.

@AndysMachines

Жыл бұрын

Thanks, interesting idea! That would allow for a lot more variation of the distance(far more than actually needed), I've never made a Schmidt coupling, but I have made Oldham couplings which are simpler and work in a similar way, however I think you'd still need the gears in addition to the coupling as they (like most flexible couplings I'm aware of) transmit drive along a shaft rather than to an adjacent one

@titter3648

Жыл бұрын

​@@AndysMachines Yes the Schmidt coupling transmit drive along a shaft, but then you could for example make some simpler sprockets and use a bike chain to transmit the rotation, and then a Schmidt coupling on one of the sprockets to be able to adjust the spacing. I think a Schmidt coupling with some oilite bushings or even some needle roller bearings would have far less friction then a Oldham coupling.

Amazing...

Gday Andy. Well designed. I guess using bigger gears (14T) for larger gauge stock would maintain tooth engagement. Is that one of your hobs? Thank for another interest machine Greg

Yes, having a selection of swap-able gears would cover a greater range, I don't know why the cheap hobby machines don't do this (maybe some do?) as they seem very limited in how thick the material can be, but maybe it's to do with the strength of the construction as well. That was actually a hob I bought quite cheaply 2nd hand, I'm always on the lookout for any sizes I don't already have.

This is great, I think some heavy die springs between the roller and the housing on the 2 adjusters would help clear backlash in the movements and make the parts more accurate. A scale might help too

I haven't seen a machine that unrolls pipe. There are machines that straighten wire (from a coil), they work by passing it through a series of rollers that bend it one way then the other, maybe something similar would work?

Have you tried rolling a cone? I'm a bit perplexed by the load ratings of oilite bearings. Being plain bearing i would think they would have higher load ratings than for example a needle bearing, but they dont.

@AndysMachines

Жыл бұрын

I haven't tried rolling a cone but I did build the machine with enough play in the guides for the rollers to be at a slight angle, I think it would only roll slightly tapering cones though. With oilite bearings, since they are sintered (basically fused together powder) I think they are more likely to crush and have a lower load rating than a bearing turned from solid bronze, with roller bearings somewhere in between. However the sintered bearings I used for this seem to be holding up fine.

Andy is it the camera angle. The thickness you mentioned as 3mm that's just under an 1/8 of an inch your piece looks thicker?

It might actually be 1/8" or a little over 3mm, but no thicker than that. It may be the small size of the slip roll making the piece appear bigger, it can be hard to judge the scale of things on camera (something special effects guys rely on).

Yes, the gears are 'detachable' as they are held with a key and snap ring (or nut on the top one with handle) so it would be a simple process to change them for different sizes.

I'll have to try this out. I mostly use handsaws on wood for similar reasons. eventually I will gear down my wood bandsaw to cut mild steel. I think that would be useful to make quick cuts with larger sawdust.

Any particular reason why 3rd roller is slightly larger?

@AndysMachines

5 ай бұрын

It's so that it can reach closer to the pinch rollers and is able roll smaller tubes. You could build one with 3 rollers the same size, but in my case the size of the bearings and positions of the rollers meant the 3rd one needed to be slightly bigger. If you don't need to roll such tight curves then it wouldn't matter either.

next make a power tap.

very, very nice setup. improved Vincent R Gingery model, in difference that top roller is almost fixed in this version (one side is used to pool out finished cylinder, while Vincent takes off his top roller completely). only thing that I will improve is 2 or 3 sets of gears, one for small thickness, second one for range 1mm to 3mm and third one for 3mm-5mm, so no needs to stress teeths with longer distance. changing a gears is simple, as I see, just align them with a key.

Thanks! I can't remember if I mentioned it in this video but it did occur to me to have a 2nd set of gears / or why machines you can buy don't do this. But actually for the range of thicknesses this machine can handle the one set of gears works fine. 5mm would really be pushing it on anything but a thin strip of something soft like aluminium. Involute gears still run very smoothly when not contacting at the ideal centre distance, the teeth just need to be big enough to handle the load.
