Clickers logic

[JaspaJami]

Greetings from Finland

I would be able to get a clicker for small money that is in quite good condition. Except circuit board is broken/missing or similar (havent seen that yet). Owner haven't been able to find replacement part for that.

Possible that its easy to fix pcb, but if not it would be possible to design new controller for the clicker. For me electronics and programming the logic is not a problem. Problem is that i don't know how clickers are working. What kind of logic there need to be  Is there some kind of adjustable pressure sensor to recognize when it stops pressing and lift jaw up? If someone can explain whole working process of the machine for me (standard hydraulic clicker, movable jaw that is pressing from up).

And maybe... i have no knowledge of wet forming leather, but maybe it would be possible to do with same machine? If i just make a separate program for that.

This document clears things a little bit: http://www.artisansew.com/pdf/manuals/ArtisanA900seriesHydraulicClickers.pdf

Have to read it few times still to really understand it.

So, there is some kind of sensor that is calculating how deep rocker head is traveling?

They aren't all constructed the same, it depend of brand and year. Some have manual hight and stroke adjustment, some electronic. Mine is old and all manual. What brand is it. Guess that the time of the stroke is adjustable on some models too and can be used for embossing/wet forming. I use a simple old cast iron book press for embossing, when time is a factor more than the pressure.

Most common models will have the safety factors of two triggers that has to be pressed simultaneously, hight adjustment of the hammer (head) and time of the stroke. Perhaps also something for the oil pressure/level and temperature, not very complicated electronics.   If you have the brand and model number you can search for a manual/ part list (pdf) for it.

Artisan model will typically be made in China or Taiwan. In Scandinavia most used older clicking machines are German or Italian made. Common European brand are Sandt, Atom, Schön and Moenus. You will also Find Canadian and US made ones. Chinese machines are of newer model but could very well have broken electronics, not their strongest knowledge  good luck

Have you tried contacting Artisan yet regarding a spare board? The PDF you linked has a reference to "One circuit board (No.: 02E03947)" that it recommends having for a spare.

I just get more info of the clicker. It is Samco SB-25 (25ton machine). Samco is same as USM?

I think Samco clicking presses was British company, I do not know if it's the same company as the big Canadian Samco company of today. Perhaps the label tells us something more? "Samco Strong Ltd" perhaps. I don't know unless I see it. USM stands for United Shoe Machinery. They are also a Canadian company that make and refurbish old leather related machinery. I have a Fortuna band knife splitting machine that is branded by USM, refurbished by them. The best thing you can do is posting a picture of the machine and label (name/number plate) I know that  Samco is good machines and 25 ton should be good for cutting saddle parts.   Tor
