I need to make thousands of fasteners consisting of 1/4" x 4" threaded
rod with a 20 degree bend in the center. The ends will each get a 1/4"
nylon-insert lock nut. I plan on doing the bend on a punch press. I'm
concerned about:

-What grade of All-thread so the rod doesn't crack at the bend?

-How to cut the rod? (parting die on punch press, bandsaw, cut-off
wheel in chop saw, etc)

-How to deburr so the nuts will start?

This is for a new product so I will be ramping up and might have to
change methods according to demand.

Do you need all 4" to be threaded?

Buy 4" threaded studs and just do the bend?

All depends on your shops fixed costs and tooling you have available.
Parting on your punch press will be the most cost effective. Use a
Outside Chamfering Mill to clean up the threads, then bend.

Best Regards
Tom.

In smaller quantities we have welded the ends of long pieces of all thread
together so we could run the bundle (10-20) through an automatic feed band
saw for the cutting. You could set up a stop on a power shear but since
you'd most likely have to feed by hand I think the saw would win. For
deburring we did it by hand on a belt sander with something like 80 or 120
grit and just put a 45 degree chamfer about 1/16" wide. This was on 6 mm
rod so about the same as 1/4-20. That's where I think you need the most
improvement over what we did.

I put a nut on before cutting with a bandsaw, then hit the edges

Ptting on 2 nuts and cutting between the nuts makes both ends useable.

ANd virtually any cheap allthread will bend 20 degrees, cold, without
cracking.

Can you buy threaded rods of the proper size, in quantity, and only
perform bending? I think that it will be a lot cheaper than cutting
allthread.

Cutting allthread to length with a punch press is very
fast and accurate. Depending on the press and die set
you could crank out a 1000 an hour easily on the right press
with a automatic feeder.

Have the raw bar stock cut to length, then stick it in a lathe with a
die or CNC lathe with threading tool, thread, remove, turn around,
thread the other end.

For CNC, Id recommend an OmniTurn CNC lathe, or for threading..a
Grisholt threading lathe, or even a basic thread roller.

The OmniTurn would be the most expensive, but Id get a commission G

The Grisholt or thread roller can be found on Ebay or a local dealer

When the two ends are threaded, stick it into a bender and voila!

Threading a blank would take very little time. My best guess would be
8-10 seconds for both ends on an OmniTurn but..shrug

Grisholts or thread rollers..even less for a simple thread roller


There are shops that specialize in this sort of part and do many
thousands a day for very little money if you supply the material

http://www.ebay.com/itm/CNC-LATHE-LA...-/130631837524

http://www.ebay.com/itm/THREAD-ROLLE...-/350351280714

While a bowl feeder May..may be set up..its a long part..so a hand feed
thread roller may be best. Dies are available also on Ebay

When there's room, I've used a die grinder and 3" cutting wheel. If
the screw is loose, I can always dress the end in nothing flat.

Look for threaded rod cutting dies and machines. There are all sorts
available. I would try to use rolled thread stock instead of cut
thread stock. The rolled threads are much better quality and the stock
bends better without fracturing. Much better. There are also companies
with machines that are just for cutting to length and chamfering round
stock. They can use coiled stock and spit out straight parts really
cheap. If coiled stock is available in the correct diameter, and I bet
it is, then threads could be rolled onto the ends of the 4 inch long
pieces. You could also use a Geometric type die head and cut the
threads yourself on pre cut pieces. I could put 1.5 inches of thread
on each end of a 4 inch long part with a cycle time of less than 15
seconds per part with a die head. Even faster if the thread is rolled.
And I'm just a job shop not set up for doing thousands of parts per
job. In case you are not familiar with die heads they open up to
release the cutters or rollers so the spindle doesn't need to stop or
reverse. As the dies head is cycled off the part a cam is set up to
close the head again. The head can be closed by hand or a cam. The
head can be opened by either stopping forward motion of the head or
with a cam.

Unfortunately not,the end user needs to be able to easily replace the

Otherwise I could glue and air nail it all together like I do with other

Well, that guy has retired and we have to start with a clean sheet and I
still don't know enough about rod grades and deburring Doing higher
volume production is a LOT easier than starting from the get-go with .
The obvious solution is to farm out the job and throw money at it.

To design and build the die work is expensive and time consuming. This
project has finally come to the front burner so it has passed from the
theoretical to reality. It might be best to resurrect the original idea
but it wasn't mine and I just can't "see" it in my head. Maybe the burr
won't be an issue but it sure would ruin production time if the assembly
operator has issues with getting nuts started.

Chances are that any rod won't crack with only a 20 degree bend but if
there is a failure problem, the buyers will drop a new product like a
hot coal.

That's the trouble with working on a number of things at the same time,
as I get older I find I can't keep as many balls in the air.

If you make a suitable jig (I'm imagining soft jaws in a vise, clamp
on an aluminum shim, drill/tap transversely and remove the shim
to make 1/4-20 jaws), then the cutoff wheel in a chop saw will do you
fine. A friction-type blade will do, too.

It'll make a sharp edge, though; the easiest way to make that into a
good nut lead-in might be to pre-grind a (ring) notch on the site of
your subsequent parting cut. I sometimes finish on a wire
wheel, but for production... that could get awkward.

Grind the allthread narrower, then cut. Deburr.
Electroplate on a little zinc/zinc-chromate/whatever.
Bending would be the last step.

Somewhere, I found a link to a video, possibly Utube, that showed a
machine that formed a "U" clamp rod to used as part of a clamp to hold
onto a steel tube, like a TV antenna mast. The operator placed a rod
with threaded ends into a holder that exactly centered to rod.

Then he pressed the "go" buttons and a round die was used to pull the
rod into a forming die that made a speci

I do have a couple of screw machine companies that do other jobs for me
and I do believe that that will be the most cost effective solution when
the quantities are large enough. I need to keep it in-house until the
product takes root.


Wire forming companies specialize in this. It may not be worthwhile to
agonize over it until you get a couple of quotes, even for lower quantities.

This is for a new product so I will be ramping up and might have to
change methods according to demand.
You have had lots of great suggestions, now for mine. I discovered this
video a while back when I was looking for u-bolts to use in mounting a
new ham radio antenna to a steel mast.

This is perfect for your need, if you just change the dies and machine
stroke. And use rods that are already threaded on the ends.

Good luck!

I had to make my own u-bolts using 3/8 stainless steel rods. Threaded
ends with a die in the lathe, then used a hand powered metal bender.

Thats a cool tool, bookmarked that video.

Using studs sounds good if your size is readily available, ie off
the shelf. If you can buy in 1000's & 10000's, pricing might look
attractive.

Do you need all 4" to be threaded?

Buy 4" threaded studs and just do the bend?

Best Regards
Tom.

I assumed it would be a LOT cheaper to use All-thread even with the
added operations.

Cool! It looks almost like the bender we made for conduit handles for
another project! I'm thinking it would be easy to adapt.

Threaded rod cutter? From Ridgid or others..

Just add a depth limit to get all pieces same length..

That's the ticket! I se a couple on ebay, it could easily be automated
or even but just the dies and set up a press.

Check that both sides of the cut are clean.
Most cutters will do one side OK, but burr the other side.
You don't want to cut twice, and waste material. Do you?
