I just dropped off my new bender at the shop after a 12hr round trip road trip to pick it up. I found it on Kijiji and the picture was so bad I didn't even realize it had the rotary bender accessory with it, no dies but the pushing dies are just going to be burnouts and I think I can adapt some Hossfeld dies that I currently use. Its a 35 metric tonne press.

I need to clean a little rust off and free up the adjustments for the limit switches. It was sitting in an unheated shop and then quonset hut for a couple of years. The guy I bought it from assures me it was working when he got it from a plant in Ottawa. I was going to build a similar press but I figure the steel and machining a thread for my enerpac cylinder was going to cost me at least the $1200 I paid for this. Works out to about $.75/lb

That's a real score John! Wowzer! That machine is going to make you a lot of money.
While you can probably make some of your Hossfeld tooling work, think about adapting your Hossfeld to mount right on top of that. Make a new center pin that can drop all the way through into a bushing so you can line everything up easy. Then make an arm to push the Hossfeld swing arm around. Way better than the Hossfeld hydraulic setup.

Metric it is spelled tonne.

I was thinking of how to put on the Hossfeld and hadn't though of a pin with a bushing. I will have to pull things apart and take a look at it next week.
Once I get it cleaned up I will have to take some better pictures and send a note to my customers letting them know I have it.

The use of the rack generate rotary motion is pretty cool. Hmmm. Nice piece of kit.

John, If you decide you should try and adapt some of your Hossfeld dies to the bulldozer directly be sure to consider that many of them are castings not designed for the loads your new machine may place on them. I found out why I had a few cracked dies in a crate of used ones I picked up a while ago when I tried adapting a Hossfeld 90 degree tubing die to my draw bender. I like Grant's idea of using the new bender to power your swing arm but remember you'll have a LOT more power than the Hossfeld setup.
Nice score for sure! Steve G

Good point Steve. If I can't set the bender up to fit the Hossfeld I will drive a piece of plate with the bender and drive a stop block with the plate rather than trying to drive the die.

Yeah, once you got 35 ton of push or turn, you can do all kinds of neat things. Especially when it's guided nicely and has connecting points on the table and ram. Certainly want to make a punch and die setup. You'll be able to use it as an upsetter too! All kinds of neat possibilities. Now you'll need to increase your machining capability. Can't remember what you got in machines. Got a lathe and mill, do ya?
What's the brand?
Here's a similar machine:

This is the newer PLC controlled version of the press I got. I am definitely planning a hot punching die setup probably a cold version as well. Upsetting is something I have thought about as well. Possibly a bar shear as well, I was thinking of a lever on a bar shear to get a mechanical advantage, I may need to shear a bunch of 1" bars which needs about 50 ton but if I had a 2:1 mechanical advantage I would have the power.
I have an Excello mill with a DRO and a rotary table for it. I had a really old Southbend lathe that took up too much space and was too old and light to take a decent cut. When I installed the Massey I had to choose between the Kinyon hammer and the lathe. The lathe lost because the hammer makes me money. One of these days I need to pick up a compact heavy lathe like an old Standard Modern. Right now if I need things turned I have to send them out.

I called the dealer this morning to get a catologue of attachments because I definitely need a couple of 80mm pins for the table. End of the day he emailed me a scan of a brochure that does not show specific parts or part #s. Maybe that info will be in the manual, he thinks he can get me one for $100.

Seeing as how you have that rotary attachment, you might think about using it to power you shear. Make an eccentric drive pin (sorta like a crankshaft) to push the shear. If the ram travels 4" while the shear travels 2" you've got double the power.

Then again, maybe a toggle link would be easier to do. Hmm, maybe your original idea of a 2:1 lever would be the easiest.
Boy, that tooling block on the ram is nice. Absolutely non-rotating too. You're gonna have lots of fun with this guy.

An eccentric on that rotary attachment could be really cool. Seems like it might take up the least space and could be a little simpler to design since most of the frame would be in tension.

I go the press wired up over the holidays, but could not get the ram to move. A week ago my dad and I finally got it running. The electronics are nice for the features they add but it did take us a few hours to get things set up right . The foot pedal wiring may have been damaged and the proximity switch for the back position of the ram needed adjusting.
I turned down a job modifying a stainless half ring just before the holidays, due to the fact it was too heavy to handle under the hammer especially forging it the way they wanted it forged. They have a half ring shaped like a washer and want it forged so the id is larger, the od remains the same and it forms more than a 180degree ring. I recommended they try a large forge shop near here.
I stopped in to see them this morning to see how they had made out when I was in the neighbourhood. He mentioned the big forge shop had turned the job down, but had recommended a big bending shop in Niagara.
As I was driving back to my shop a light went off in my head, I could forge this job with my new press. When I got back to the shop I did some experimentation and called the machine shop back. Looks like I have the first job for the press.
