- Dear Eduardo;
You are right, we have seen some deposits on coiler when there is a undersize wire, we wipe out deposits and keep going. Also sometimes when we face with undersize, and couldnt find anything although check all die dia, bearings etc. About die profile, what we have to check ?
- Thank you for your valuable help.
About variation in lubricant content on wire, how can we measure or observe the content of lubricant on final dia wire. We use inclusive Na and Ca lubricant on wire drawing dies. In order to clarify the problem and do some test, how can we draw the wire for see the differences on spring machine ?
- This problen can be due to:
1.- Misadjusments on the tools of the spring making machine
2.- Variations on lubricant content on the wire causeing different slips on the guiding tool of the spring making machine .
3.- Variation on types of lubricant used wich causes to adjust the machine different for each type of lubricant.
4.- Variationos on tensile of feeding wire
1.-Consistency on type and content of lubricant used on the wire
2.-Consistency on wires tensile
3.-Proper and continus adjustment on tools of the spring making machine
- The undersize might be due to deposits on finishing dies , deposits can be due to lubricant geting harder inside the dies instead of flowing or if wire is galvanized , it can be zinc been deposited inside the dies.
Check on type of lubricant being used, die profile(very important) and if it is galvanized wire, on zinc adherence.
- Dear all;
We drawing wire for bedding spring but sometimes our wire and spring machine is run with good and sometimes run with bad. When run with bad, we see the spring different shape or changed with height etc. We now that we couldnt change anything but our wire is sometimes good , sometimes bad on run with bedding spring machines. If the only variability is wire rod, do we search the problem on wire rod ? or investigate something else.
- Dear all;
We have undersize problem on our wire drawing machines and also we couldnt find the root cause of this. We draw high carbon wire rods and for instance our last die is 2.18 mm but sometimes we measure 2.02 mm. Is there anyone help about this situation ?
