Hammer press equivalent to 6 Ton hydraulic press

AI Thread Summary
A 3-ton hammer press may be used for forging operations previously done with a 6-ton hydraulic press, but the processes differ significantly. The hydraulic press applies pressure gradually, while the hammer press delivers rapid impacts, potentially affecting the material properties. There is no exact equivalence between the two types of presses, as the deformation rates and die requirements vary. The actual force needed for the forging operation may be less than the maximum capacity of either press. Therefore, it is possible to achieve similar results with the smaller hammer press, depending on the specific application and conditions.

TL;DR Summary
i need a help, this is my first post in this platform, actually few year ago I perform a forging operation in a 6 Ton forging press but now i have 3 Ton hammer press, can i use that press to make that product.
is there any calculation to find out equivalent hammer press of a forging press

I'm really no expert on this materials processing question, but I doubt that an exact equivalence can be established. With the hydraulic press, the metal deformation is relatively slow and continuous. With the hammer press, the metal deformation is very rapid. I would expect significantly different properties in the resulting forged material in these two processes.

Welcome to PF.

The rating in tons is probably 1:1, only the time is different.

The forging press would build up pressure on the die gradually, until the process completed. The hammer press will apply a single impact, that may require the dies be mounted differently as excess force must be carried by the die.

Is the pressed material hot or cold? Is the workpiece being bent or coined?

If the process was previously done OK in a 6 ton press, that does not mean it required all 6 tons. It may only require one ton, so it could well be done in the 3 ton hammer press.
 
Thread 'What type of toilet do I have?'
I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...
After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
