Multi-wire Drawing Machine
Usage
Our multi-wire drawing machine was designed to greatly increase production capacity compared to standard drawing equipment. The drawing line can draw up to 16 copper wires simultaneously. This efficiency increase is invaluable to high capacity wire producers.
16 wires multi-wire drawing Equipment description
Quick die change system: Allows the production of various diameters without exchanging the complete die sets; The rpm adjustment of the last capstan to the final capstan (necessary due to omission of one or several drawing steps) is pre-set by the 2-motor-technique in connection with free- programmable control (PLC).
Drive of annealer and contact pulleys: By endless flat belt in the annealer, drive directly from the drawing machine by flat belts; belt tension can be regulated via tension pulley.
Wire traverse mechanism:Driven by AC servo-motor;
a)Constant traverse speed:When in this mode, the traverse pitch changes with the filling degree of the spool, which means , the traverse pitch increase with the spool getting fuller. The filling weight is lower than with constant traverse pitch
b)Constant traverse pitch：The traverse speed will be adapted to the spool speed when in this mode. The traverse pitch is kept constant during the complete winding process
Option: automatic adjustment of traverse width.

Multiple Wire Intermediate Drawing Machine(8/10/14/16/20 Wires)
A Multi-wire Drawing Machine is an industrial equipment used to draw multiple wires simultaneously. The machine consists of a main drawing unit that pulls several wire rods through a series of dies at the same time. The wires are then fed into individual take-up spools, where they are wound onto reels.
Multi-wire drawing machines are often used in the production of fine wires, such as those used in electronics, telecommunications, and medical devices. By drawing multiple wires at once, these machines can increase production efficiency and reduce costs compared to drawing each wire individually.
Some multi-wire drawing machines are designed to produce wires of different diameters or materials simultaneously. These machines may have multiple drawing units, each with its own set of dies and take-up spools. This allows manufacturers to produce wires with varying properties in a single operation.
