Hey Judson and Thomas. Thanks for the info!
@Judson yeah 4.5t is pretty meager. I will have to get a cylinder that is at least twice the size (100mm bore). I worked out I can get around 15t at 3cm per second at 200 bar if I do that. It just means I have to modify the H-frame I already built. But thank you for the valuable information. I was thinking of using small surface area drawing dies, but I think it just won't be enough in the end and that is why I started this topic.
@Thomas the billets are on average roughly 10cm x 5cm x 5cm (kinda enough to make a big Bowie knife with some spare material). I have built a leafspring (Appalachian) type power hammer that I usually use for drawing out after welding by hand, but I feel it is just not moving the steel fast enough and I was drooling over some forging press videos on youtube. But yeah, maybe I can simply use the press for getting better welds and see how I can up the ram weight on the power hammer or improve my drawing dies until I find the hydraulic parts I need.
Will see what I can find in terms of 100mm bore cylinders on my local classifieds today.
Thanks again for the info and have a nice day
