Both my grandfather and great grandfather were both wire drawers at Bruntons. My grandfather helped to draw the wire for the Forth Road Bridge

Thank you don for coming to itc and sharing your knowledge

If the die box is not locked down tightly after adjustment or if the wire is scooting up the block as it gets hot, the helix can change. Is the helix change happening on a standard push up block or is this occurring on a dead block? Also if the die bearing is very short say less than 10% bearing length it is hard to control helix.

What kind of material do you do on your machines?low/high carbon.. Inox?

Both high and low carbon

I think That this process has sense only on the last block Before the spooler .. In the other blocks the wire should work as straight as possible against the capestan.. What do you think about? I work on a 13 blocks machine

Of course setting the cast and helix on the last block is very critical but the cast and helix should be set on all the other blocks as well. And yes the wire alignment going into the die box might not be a straight line because how you have to move the die box to get the proper cast and helix. but if your die geometry is correct this should not be an issue. For proper removal of wire from a block the cast and helix needs to be correct.. If you get a break at these blocks with wrong cast the wire will slinky off the block and could cause an injury. plus if the cast and helix are incorrect at each block it makes that much more difficult to adjust proper at only the last block .

Is it common for the start and finish of a run to have radically different helix? I can start the job with a 0” helix but end with 5” helix by the end. Any suggestions?

yes, the die box alignment is the most probable cause. Also, check your drawing speed.

If someone is setting the helix with a die only there are two things that can cause it to change once the machine is up and running. First if the wire is slipping or shooting up the block as the machine starts running, this will cause a change in the set helix, also if the die box is not lock down properly it can move during the run the helix can change. If someone is setting the cast or helix with casting rollers, like on a dead block flier the setting can change as the wire warms up and the rollers heat up and expand. This expansion in the size of the roller is just like slight moving that roller in. You usually only see this with small diameter wire. Also, more often when using rollers, is if the bearings in the roller are going bad, the dragging of wire over a roller that isn’t spinning smoothly or not turning at all will definitely cause the cast or helix to change. When turning slowly or if even when a roller bearing is in your hand it is very difficult to determine if the bearing will run smoothly at high RP Hope this was helpful

Hi Sir, I am interested in learning about die series like the dies set which are used to reduce from 5.5mm Dia wire to 3.20mm dia in 6 blocker machine please make a video on this topic or send me the links if u have any study materials, Thank you 🙂

Panchaksharaiah Hiremath I have a die program that can determine your die set up for a reduction of 5.5 to and finish size as long as you know the number of blocks you want to us. Send an email to meet at DYoung 6775 at gmail.com and I will forward you the diet program if that's what you're looking for Don Young

Not quite sure what you mean by overcome the turns. If you mean the wire is overlapping the strands above it on The block this could be that the Helix is not set properly and the dancer response it's not working 100% correctly so when the machine changes speed The Wire becomes loose a little bit on the block and if the helix is incorrect the wire will jump over some of the other strands already on the block. You must have a dead helix set coming out of each die so this does not occur. Without seeing the actual problem in a video it's hard to say though.

Most people don't want a negative helix👎🏼 #reject
