Building 2 inch press dye?

admin

Just bought 12 ton shop press. Looks to be 1 inch shaft press. Are dyes used to shape the down ram to fit a surface, like round to square or rectangle? Have never seen one of these things used nor have I have an idea of building a dye without placing side pressure on ram. I'm looking to smash 2 to 3 inches of 1 7/8 .065 pipe flat. Got about 50 to do. Don't tell me its easy, already did 6. Would not smash when trying to do it on concrete. Had to go to anvil. Not a fun job with a 4 lb slag. Looking for help building dye. Got plazma (max30), 175 amp meg welder. I'm thinking 1/4 inch would be fine to build a dye out of for 1/16 inch pipe. A nice shape would be 3 inch square dye. What would the connection to ram look like to minimize stress? I could cut 1 1/8 hole into 1/4 plate. Maybe 3 plates with holes then a solid piece on bottom, don't know if this will work.VernLast edited by Vern2; 12-04-2009 at 01:01 PM.

Reply:Hello Vern, is the plate that the 1" shaft is welded too solid? If so you could re-drill some of the table holes so that the table could be located closer to this plate and use this plate as the top punch and the press plates on the lower table as the bottom dies and flatten two pipes at a time by positioning one on each side of the 1" press shaft. Hope this explanation makes sense. Best regards, Allanaevald

When your dealing with 2 1/2 acres of fence that is. Gates and carrels are notched, and fully welded. I had 2 bids over $12,000 for just 800 feet. Thats why I'm doing some of it myself. Vern
Reply:I'd do that with the big bench vise. Insert tube and start cranking till it got mashed flat..No government ever voluntarily reduces itself in size.

Reply:Ya need to make a heavy duty hinge.  Insert pipe into hinge and press flat.  Your hinge plates will stay aligned and not side load the ram or spit the tube out.My name's not Jim....
Reply:I don't want to design anything. Takes to much time, been their, done that.Here is the dye I built. I know it's crude but it works. It's all 1/4" plate, I wanted it strong and functional. http://www.enichesoftware.com//dye.wmvVernLast edited by Vern2; 12-06-2009 at 12:16 AM.
Reply:Thanks Prop- Doctor!!! Now I just push a button. Thanks again.Do it with a BIG VICE, I did try. I have a 6 inch vice with built in anvel( I know not a big vice, but a BIG VICE costs more then a shop press. Go price one. I was using a hammer on the vice handle. It would not smash it FLAT. Plus I can't get 21 feet of pipe to the vice. I did use the anvel part of the vice to smash the other 5 ends I had to get done, for a 3 ft turn in the fence. Had a problem with telephone wire where I wanted the fence.Just got 12 ton air over hyd bottle jack $64. A direct replacement for the crank 12 ton bottle jack ( I needed a jack anyway, my truck weights 7,200 lbs, with me in it 7,425 lbs). Now I can stick 21 ft out the 16 ft garage door. The air jack puts out more pressure then the manual one. How do I know? The dye I built fits a 1 inch round ram. When welding together the socket is smaller at the bottom then the top. The ram fits tight at the top. The manual jack would not press the ram to the bottom of the socket when smashing pipe. The air over hyd, pushed right to the bottom. Now to get more use out of the shop press, I'll have to figure out how to build a pipe bender attachment.Aevald, That would work. But I did not go in that direction.VernLast edited by Vern2; 12-06-2009 at 08:47 PM.
Reply:Looks like it's working. You really want the die to be a loose slip fit with a set screw to retain it. The press nose will mushroom a little in use and a close fit will always be a pain. Use a die grinder if you need to open up the socket. A drill bit will catch and make for an ugly process. If you want to make another die, make the socket with 5 sides in the shape of a house with at least 1/8" clearance around the press nose. Drill a hole and weld a nut on for a set screw coming from the side opposite the "roof" of the house so the nose of the press is held in the corner for alignment. Use at least a 3/8" bolt for a set screw. Align the socket on the die so the press nose is centered in the clamped position.Lincoln SA200, HH135, Lencospot, HF80 Inverter, Rockwell 11x35 lathe, HF drill mill, Kama 554 tractor w/ FEL & BH, Belarus 250AS, lot's of Chinese tools
Reply:Wow! Thanks Brad. Just the info I need. I bought a larger Drill Press for the 1 inch drill process. I know thats a nasty job. The dye foot is off center so I can place pressure where I need it. It makes for a better looking job. I could drill a 1 1/8 hole Or even make a new one. 5 side like you suggest. My only problem is aligning the sides (house), to tack the socket together. I use magnets to assist in the lineup. I'm telling you the 4 sides were rough lining them up, and I still did't get them perfect. My Max30 was built for this 1/4 inch stuff. Then the SP175 plus lincoln is perfect for the weld. If 1/4 inch is to small I stick another 1/4 plate to it. Don't have any 1/2 in shop. VernLast edited by Vern2; 12-07-2009 at 10:53 AM.
Reply:I think I figured it out. I'll build it right on the press.cut 5 sides, 2" long. Drill 3/8 holes for set screws.weld nuts.put the 5 sides on the ram.wire them together.tack to 1/4 plate. pull it off, take it to welding bench.VernLast edited by Vern2; 12-07-2009 at 06:45 PM.
Reply:Sounds like a plan. Wrap something around the press ram for clearance. Maybe a strip of aluminum can or some wire. (non-flammable stuff) It will shrink a little as the welds cool.Lincoln SA200, HH135, Lencospot, HF80 Inverter, Rockwell 11x35 lathe, HF drill mill, Kama 554 tractor w/ FEL & BH, Belarus 250AS, lot's of Chinese tools
Reply:I forgot about that thanks. It would not have worked.Vern
