Sweet! You got a really good knack for precision! Excellent work!

Fascinating machine, very ingenious and amazingly good result. I feel an undeserved affinity with ball chain - during the war my father (a very able engineer with whom you would have much in common) was given the task of mending a machine for making ball chain that had been in a bombed factory; apparently there were only a couple of such machines in the country, most being imported before the war, and these chains had some application as timing chains in some form of military equipment, I don't know what, not sure he ever did himself. The chain making machine was itself originally German, ironically. But I have a very vivid memory of my father, in the 60's when I was a boy, describing to me how such machines worked, fed by a coil of wire for the dumb-bells and a coil of strip for the balls. Made in a continuous process of course, a blank for the ball being stamped out of the coil into a hemispherical die, between the counterpart of which the dumb-bell wire was fed in, rapped sharply on the end to form the dumb-bell as almost simulaneously the dies closed around it forming one end of the ball, the half-dumb-bell then being sheared from the coil, another sharp rap on the other end, providing the dumb-bell end ready to accept the next ball-blank. All happening very fast and noisily. That he could reconstruct the machine with no drawings further convinced me of my fathers genius, and simultaneously revealed to me how much better his 3D spatial imagination was than mine would ever be.

Hi Andy, excellent video as always. I don't know what kind of PU rubber you used, but if you have control over the curing time that would help an even distribution with in the mould I'm sure. I say this as someone who would like to make large scale tyres but don't really want to/cannot justify for such limited use, the lengths that you have gone to achieve it. As others have have mentioned, I also would love to see the production of the tyre mould too. Regards Mark in the UK

@AndysMachines

2 жыл бұрын

Thanks! I tried two different types of rubber with working times of ~10 minutes and ~ 2 hours. I thought the longer curing time would be easier to work with, but actually found the opposite. There is an effect known as 'flash curing' where if you have a large pool of resin rolling around inside the mould, this tends to set first and form a large lump. Also I thought slow speeds would coat the mould more evenly, but found faster was better. It doesn't seem very intuitive and I'm learning as I go. The viscosity of resins can also vary a lot, which is another factor to deal with.

@@AndysMachines Let me first say i design and build proffesional rotational mould machines (for plastics like LLDPE and PP), and i am impressed with what you have made. I can confirm that the higher speed should be the best. the most standard setting is 8:4 (8 rpm for the arm and 4 rpm for the form). When your moulds get more assymetrical 8:2 might work better. Unfortunately you can not change that. Maybe an upgrade for the future. Another thing that can help with assymetrical or complex moulds is to change direction during casting. We do it around each 2 mins (in a 10 min cycle). so in your case it would probably be a little quicker. I hope this information helps a bit and looking forward to more videos.

@@AndysMachines In conventional rotomoulding aka heating the mould from the outside to melt plastic, thin and thick spots are created by having either hot or cold spots, material builds up more where it is hotter. In your case it can only be controlled by your rotational speeds of the arm and form. But keep in mind that the amount of material versus free space in the mould matters. i would also try to decrease the amount of material you use and see if that gets a better result.

Neat project. I was wondering if you could get away with using string instead of ball chain though. I guess it would depend on how much torque it takes to swing the resin (the mold can be balanced before filled). A cord and pulley transmission works fine on a spinning wheel, where one is amplifying rotational speed rather than torque. I'd think that your application doesn't require a precise ratio, so a small amount of slip could be tolerated. Could you estimate how much rotational speed is needed by measuring the flow rate of the resin? I wonder if measuring the motor current is accurate enough to guestimate where the resin is inside the mold?

@AndysMachines

Жыл бұрын

Thanks! Yes you could use string, or better round rubber belt (comes in long lengths and is easily joined to make any size belt) but as you say it wouldn't be synchronous which isn't so important but it would be much more likely to slip than a toothed chain or belt so would need to be run with higher tension. One nice thing about it being synchronous it that you can stop it with the mould dead horizontal every time which makes filling it much easier, if there were any slip it would no longer be horizontal in both planes at any point so you'd have to make do getting it as level possible or adjusting it by removing the belt. As for getting the correct rotational speed, this seems to be non-intuitive and needs a bit of trial and error. The current measuring is an interesting idea though!

I wonder if you could have left the bigger locking link in place rather than build the tool to join the dumbbells by cutting a single special indent in the pulleys for it...assuming that the ratios of the pulleys and chain length could be adjusted so that the big link would always fall into those special slots, and assuming the chain never slips.

I did think of doing something like this (removing every other tooth). However the small pulley has an odd number of teeth, so this wouldn't have worked, but with an even number on both pulleys and an even number of beads on the chain it would. I expect the chain would break before it ever slipped

I'm curious - could you carve the drive gear as if the whole chain were made of those connector links? Once aligned, wouldn't it just work the same? Each "tooth" would hold two of the beads instead of one _and_ accommodate the connector link. In my head it works. Not sure about real life. The only gotcha would be making sure an even number of beads on the whole chain so the connection link always lands appropriately aligned, and not across two holes.

True. Other people suggested that too but failed to realise that both the chain and pulleys would all have to have an even number of teeth/links. The way I did it was more work, but it just seems better to me (if only marginally) and gives more flexibility, eg. I can change the ratio by just changing a pulley and shorten/lengthen the chain without having to keep track of the number of links (yes I could just use trial and error and cut off one more ball if it was an odd number). Somebody suggested it might work better with a 2:1 ratio instead of 4:1 and I've been toying with the idea of 3D printing a new pulley to see how that compares to a machined one.

The controller is built from an Atmega328 MCU and an OLED display, there is a home-made optical encoder that measures the speed, the output is just a selectable PWM signal, there is no PID loop or anything to maintain the speed, the gear reduction and fact that the mass is fairly well balanced keeps the speed constant.

2 жыл бұрын

It's an idea, but it would spend over 90% of the time going at the wrong speed. As I understand it the goal is to avoid a large puddle of resin pooling in one spot, the resin generates heat as it cures which speeds up the curing and can cause lumps to form where the resin pools. Some people have suggested reversing the direction periodically can help, but mainly for less symmetrical moulds.

I figured this would be for a cold casting process, but then the synthesis of PUs is not exactly a cold process as the polymerisation of isocyanates is exothermic.

Why did you go through the trouble with using a chain like that? It seems to me that the exact rotation is rather uncritical, so a normal flat belt would have been my choice to save a lot of time. In the end it's your machine :) Great work as always!

@AndysMachines

I just think the chain is a slightly more elegant solution than a twisted flat belt, but either would work. There are examples on KZread of people using a twisted toothed belt for this and it looks like it works fine even though it might look a bit odd to use the belt this way. The load and speed are very low so the twisting doesn't really affect the belt. The design of the machine is almost the same so the only extra work involved was in making the chain into a loop. The machine doesn't have to be perfectly synchronous, though it is nice to be able to stop it with the mould horizontally level for filling with resin. Even a round rubber belt with non-toothed pulleys will probably work fine.
