Manufacturing Technology

Videx has adopted a new technology to allow its dual side straighten and cut machine to feed two high-speed thread rollers, one on each side of the machine, at an overall speed of 50 metres per minute.

The straighten and cut machine feeds and cuts wire at high-speed and diverts the cut-to-length bars to the two sides of the machine, from where they are fed into two powerful thread rollers that were specially designed to accept these bars and thread them at high-speeds.

The dual side lines are ideal for the large volume production of threaded rod, both for long runs and for short batches. The production rates are 2-6 times higher than in standard lines, using less floor space and at the best quality, as well as eliminating handling or operator intervention. 

Despite being dual side, each side of the machine is independently operated and controlled, enabling the machine to keep working on one side when the operator changes thread rolling dies on the other side, for example. The machines are also equipped with quick changeover features for bar diameter and length.

Furthermore, the line is highly reliable and fully mechanical and there are no clutches or hydraulic components, making it quieter and more reliable – requiring minimal maintenance. The cutting operation is performed by a rotating cam, driven by an automotive type gear through a servo drive. Wire straightening is performed by a straightener that reciprocates during cut-off, so it does not damage the wire as it never twists on the wire in one place. The machines are offered in length of 1m, 3m or 4m. Videx Machine Engineering Ltd is also offering bundling machines for galvanised threaded rods.
