SinDoc Posted September 1, 2021 Share Posted September 1, 2021 Stumbled across this video on Youtube and thought it was a cool watch. Quote Link to comment Share on other sites More sharing options...
anvil Posted September 1, 2021 Share Posted September 1, 2021 I don't know your experience level, so say this as a general comment. The thing to notice with these industrial forgings is that the only difference in this and what you can do in your shop is the power and size of the iron. The techniques and tooling used used to achieve the different forgings are no different than what you would use in your shop. The benefit here is with such large iron, and the time frame due to the mass of the billit allows us to see just what techniques and tooling are used.

Frazer Posted September 1, 2021 Share Posted September 1, 2021 On this large of a scale it does make it easier to see what's going on. The butchering dies they were using to form several diameters along the shaft in the first 2 minutes or so are exactly like those you would put in a guillotine tool for making tenons. I'm guessing they use a lot of H series tool steels in that plant... Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 1, 2021 Share Posted September 1, 2021 Well the smith sitting in an airconditioned room using a joystick is a bit different than me standing at the anvil with sweat running down my face...But I had the same idea---same as what we do only writ large!

Frazer Posted September 1, 2021 Share Posted September 1, 2021 I'm sure the guys in the latter half of the video the end have some sweat running down their face. You can also see there are (and I'm stating the obvious here) safety procedures they're following while working around the hammer. For example the guy around 5:30 keeps his tongs flat on the "anvil" lets go of the piece every time the hammer is about to come down. A similar precaution is taken (letting go of the handle) with the guy around 7:30. I think it's safe to say if the reins/handle jump in an unexpected way he would loose the battle of competing forces. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 1, 2021 Share Posted September 1, 2021 Two different set-ups on opposite sides of the world. I think I've seen the Asian outdoor one before with some pictures of the entire hammer included and fewer safety equipment in use. Quote Link to comment Share on other sites More sharing options...
SinDoc Posted September 1, 2021 Author Share Posted September 1, 2021 I thought the same thing about it being identical to what we do in our home forges, but with MUCH larger presses and bits of hot metal lol. One of the follow up videos showed a 17000 ton press doing work. I just thought it was neat to see and a couple other videos pop up with that one showing other large scale forging I thought to myself "that's cool".

Frazer Posted September 1, 2021 Share Posted September 1, 2021 It looks like they are using coal fines as their punch lube/release agent. That's what I use and they work, well, just fine. I have more fines around than graphite slurries.. Quote Link to comment Share on other sites More sharing options...
TWISTEDWILLOW Posted September 1, 2021 Share Posted September 1, 2021 Wow did y’all notice how much scale fell off around 1:06 Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 1, 2021 Share Posted September 1, 2021 You know that there is an IFI member that works as a Metallurgist for a big USA open die forging company, Scot Forge. Quote Link to comment Share on other sites More sharing options...
TWISTEDWILLOW Posted September 2, 2021 Share Posted September 2, 2021 I wonder if you could fill a 5 gallon bucket with the scale that came off that one piece after it was done Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 2, 2021 Share Posted September 2, 2021 And have lots left over! Quote Link to comment Share on other sites More sharing options...
SinDoc Posted September 2, 2021 Author Share Posted September 2, 2021 I watched another one on lunch where they made giant gears. One shed enough scale to probably fill a 55 gallon drum lol. Quote Link to comment Share on other sites More sharing options...
