Multipass Wire Drawing Machines

Type TD and type DSD Wire drawing machines

Eurolls has two families of dry-drawing machines, particularly suitable for the production of wires of low-carbon steel, high-carbon steel, stainless steel and special alloys, using both reduction by die and reduction by cold-rolling. The TD machines are traditional multipass lines with die or cold rolling cassette reduction, with tilted blocks and speed control by means of sensing rolls. Rotation of capstans is obtained through AC Motors, connected by means of gear-boxes. The DSD machines instead are an innovative design and differ from the traditional TD machines mainly because of the use of multi-pole (usually 8 to 32) AC Motors permanent-magnet synchronous type, connected directly to the capstan shafts, therefore eliminating the use of belt transmissions or gear-boxes.

Standard configuration of Eurolls dry-drawing machines includes sturdy, vibration-free, modular steel frame, tilted capstans made of forged steel C50, tempered and induction hardened to 62 HRC, coated on the lower-band in contact with the wire by black ceramic or TC hard facing. Capstan cooling using high-turbulence water flow is even more efficient thanks to our very own patented solutions. It is possible to use rotating or fixed die-boxes, and interchangeable with Eurolls cold-rolling cassettes.

Special Applications

 

Lines can be supplied with many optional elements such as for example

  • overhead pay-off on the first block
  • stripper capstan or double deck
  • capstan with accumulation (Barco type) at the last block
  • ecological casing with eventual dust extraction
  • laser gauge for control of finished wire diameter
  • production control through the video-keyboard
  • centralized control through remote computer

 

The main characteristics and performances of the two families of machines are shown in the tables above, but with the competence and experience of their engineers, Eurolls is able to offer special machines made according to the most demanding requirements of our customers.
