Making thread on bars.
Hi,
I’m a medium size bolt producer. I do my bolts with straight bars and straight reinforcement bars. (I don’t use bars in coils.) I cut or roll a threads on bars and re-bars. (mainly on re-bars) Before cutting or rolling thread I have to prepare a head of the bar - I peel it. I know that there is different possibility. Instead of pilling I could extrude the head of the bar, and it would look a same like after peeling. My problem is that I know there is such a technology, but I don’t know any producer of machines which do such a thing. Can any of you help me? Do you know any factory which do such a things? (In Europe or anywhere else.) Thanks for any clue. |
