longlandy Posted July 23, 2010 Share Posted July 23, 2010 I have a large press brake but this is tied up with production work.Having opened up a 4x4 workshop at another premises I have the need of another press brake on site to save a 20m journey. The reason for this post: 1 I dont want to buy one, cant find one to my specs and lastly I have a pile of 50mm plate waiting to be used so Im going to make one.The specs will be 1000kn force ,up stroke design for simple ram set(got some ex mod 400bar units)with a 2m capacity being the biggest machine I can machine. I will start a build thread if anyone finds this interesting ,if not i'll shut up! Quote Link to comment Share on other sites More sharing options...
Gazzar Posted July 23, 2010 Share Posted July 23, 2010 Please build and post pictures! Please do not shut up. Thank you. G Quote Link to comment Share on other sites More sharing options...
steve b Posted July 23, 2010 Share Posted July 23, 2010 How will you balance the rams for offcentre loads? It would be good to see your build up if you are doing it . I use a 250T 3m Colly a lot and many years back I spec'd and installed 2 Bronx cnc Press Brakes for a new product line , they are such versatile machines cheers Steveb Quote Link to comment Share on other sites More sharing options...
western Posted July 23, 2010 Share Posted July 23, 2010 I have a pile of 50mm plate waiting to be used Hmmm, best Nige [H_F_H] doesn't get near that pile of plate It would be interesting to see. Quote Link to comment Share on other sites More sharing options...
longlandy Posted July 23, 2010 Author Share Posted July 23, 2010 My first pressbrake was a colly 70t, I purchased it as a non runner for £400 ,it improved my french trying to talk to the factory for parts! Im going to use a crank arrangement to contol balance almost like a overcrank mech brake and the colly, the idea being to avoid any specialised hydraulics etc overwise costs will rise and to make it so home builders could copy it on a smaller scale for 3mm or so chassis parts over 3' Quote Link to comment Share on other sites More sharing options...
steve b Posted July 23, 2010 Share Posted July 23, 2010 That would be a great thread , I guess with a scaled down version one could use hand pumps such as Dowty or even bottle jacks, lorry cab pump/ram combo's would work too I reckon , yeah would be a good thread LL , get to it cheers Steveb Quote Link to comment Share on other sites More sharing options...

steve b Posted July 24, 2010 Share Posted July 24, 2010 I'm sure you are much more accurate than that Nige ..I usually end up having to open up the clearances...training as an engineer and working as a fabricator means I have to keep an eye on whats going to be reality when its cold.......if you see what I mean ...cooling slowly Steveb Quote Link to comment Share on other sites More sharing options...
Astro_Al Posted July 27, 2010 Share Posted July 27, 2010 There is a good home-built pressbrake thread on pirate 4x4 in the shop & tools section - check it out. I recently found one in a scrap yard. Apparently it had only been used a few times in a light aircraft repair place before ending up there. Keetona, 8ft wide. But the muppets had left it out in the rain and completely ruined it... Still wanted 2.5k though. I tried to tell them I could buy a good used one for that, but they weren't listening. Good luck. Al. Quote Link to comment Share on other sites More sharing options...
