Added power to my manual 20 ton Roper Whitney punch

admin

I have a 20 ton Roper Whitney C-punch.  I wanted to try to add some power.  This is what I came up with.  The worm gear came from a Harbor freight winch.  Not pictured are the wheel bearing that are in the top and bottom of each 5/8 inch plate.The first photo shows most of the parts I machined and purchased.The last photo shows a 9/16" hole in 1/8 inch channel.  The motor moves the punch right through the metal.The motor is from Harbor freight 440/880lbs. electric hoist. I use it on my ring roller, also.  It is a good, cheap project motor with a low gear and brake.   The problem is it is slow, real slow.  It takes 80 revolutions to get the punch to travel the full distance.  The motor turns at about 60 rpm.  If I could get the tool to travel twice as fast then I would be satisfied.  The punch never has to travel the full distance any way.  I got function down, now I will can work on the form -yeah right,  most of my shop use/ shop made tools stop developing at the functional stage.Any suggestion on how to speed this thing up would be helpful.

Reply:I  like that  .. You did good.
Reply:Tap - very cool but I was thinking the gears would be turned vertical, not horizontal. Then I saw the pics, maybe put the gears the other way?John -  fabricator extraordinaire, car nut!-  bleeding Miller blue! http://www.weldfabzone.com
Reply:Thanks for the comments.  Microzone I assume you are talking about driving the punch directly.  I haven't tried to drive the gear directly.  I am not sure it will develop enough power to punch the metal without the worm drive.  I think it takes 8 tons of force to punch 1/8" steel at 9/16"hole.I don't know how to get worm assembly to form something other than a 90degree drive setup.Thanks guys
Reply:I guess I am questioning what drives the punch pin in a downward motion. The worm gear lays horizontal and just spins the larger gear, so how does the shaft move down? That's why I thought it would be easier to flip the stuff. John -  fabricator extraordinaire, car nut!-  bleeding Miller blue! http://www.weldfabzone.com
Reply:The punch has a large acme thread screw.  It travels 1/2 inch in one revolution when turned manually.  The assembly requires 80 rev to make the punch travel one revolution.Any way I guess I'll have to push it aside for a while until I get some decide what to do next.

Reply:smaller drive gear?
Reply:I had to look at those dang pictures quite a few times before I put it all together.  Without having to re-engineer everything you did I think the only way to speed it up is to have a drive motor that turns faster OR use one of those torque multipliers where you drive one side and get 1/2 speed out the other end or drive the other end and get 2x the speed out of the other side. They are reversable. Can I throw a curveball at you? HF sells some REALLY inexpensive Air impact wrenches. You could have mounted that with a socket on it and do a direct drive to the Roper Whitney. I dunno about the RPMS on that either though.Or how about a hydraulic motor in a direct drive?I dunno, I am just thinking out loud.

Reply:Thanks Joker.I will check the out the Impact wrench.  I don't know if my compressor will drive it.  Great Ideas.I don't mind reengineering.  I got tired Sunday night and just wanted to see it work.  If I could find a distributor of gears locally I would probabaly be able to get a smaller setup.Hmmm...Being a worm drive a hand drill might to the trick too.  Wow, thanks for giving me a creative jolt.
Reply:Scratch the drill...my drill anyway.  The rpm (600) is right, however. It might do 1/4" but not 9/16.   The HF impact wrench say 4.5 cfm is needed,  however they don't say how many psi.My speedaire compressor is 2.5 hp with 5.5cfm@90psi.  Would that drive the impact wrench?
