SPM or IPM on Hydraulic Presses

Well, the presses at our shop do run, so it wouldnt be bad to count, but the 3 new ones have been out of comisson for a few years, and arent currently running.

...and the manufacturer's information should be there somewhere, even if it's on the end of a telephone call, perhaps?

It would need to be, if any of the out-of-use ones were to be recommissioned!

I crawled over them head to toe, couldnt really find any spec tags, just S/N and Model numbers, these are older presses from the 60's and 70's so i didnt know if they did that back then or not. I have a Pacific, and a few lake erie's to look at. Do those still have a tech support lines?

Can't find anything for Lake Erie Eng, but this company does repairs...

you should also be looking at controllers in relation to speeds,eg for multiple bends or parts you can program the top tool to retract only 50mm after each process instead of its full stroke between operations. Depending on light /laser curtains and your mute point you may actually have to slow the press down if it comes down to fast to make sure you dont over run the mute point. Whilst you can get raw data on how fast a press operates a lot of it has to do with how the press is programed rather than raw speed.

Hi

You need a circuit diagram for the hydraulics on the press. Then you need the parts numbers of the pumps valves etc. It is a start from basics to re-engineer the hydraulic system to make things go faster. There are several ways of engineering hydraulic presses.

Firstly describe the press, i.e up stroking, down stroking, what is it pressing, pressing stroke, maximum daylight, current speeds etc. There is a company in the Uk who for more than 40 years have been doing upgrades on all sorts of presses. I can put you in touch if that would be helpful.

We have a tool that is called the Smart Stop Time Analyzer (www.jokabsafetyna.com). We use this to calculate safety stop time of machines but it will measure and graph every stroke with distance and time. The whole process is recorded and can be printed as well. Check it out.
