Definitions
- the invention relates to a method for the continuous production of metal wires according to the preamble of claim 1 and a device according to the preamble of claim 6.
- the round wires are first pulled down on a multiple drawing machine and then formed into the flat wire in a final rolling process.
- the present invention has for its object to provide a method with the flat wires in one operation from round wires in an economical way can be produced.
- the main advantage of the invention is the fact that the step "Flattening" integrated in the drawing process carried out at high speed becomes. No flat wire with an exactly rectangular cross-section is produced, but instead a wire with a cross section in which the long sides are parallel to each other run and the narrow sides are rounded.
- the flat wires that can be produced according to the teaching of the invention are preferred Use as shielding wires for electrical cables and wires. They are in the Able to cover a larger area with the same metal weight and thus lead to considerable savings in weight and costs for cables and wires.
- the flat wires have a thickness to width ratio of less than 1: 5, the flat wires can be braided on braiding systems to process.
- FIGS. 1 and 2 Exemplary embodiments explained in more detail.
- Figure 1 shows a side view of a drawing die 1, which consists of a lower part 2 and an upper part 3 is constructed.
- the lower part 2 is preferably fixed on a base arranged.
- the upper part 3 is also fixed in its position to the lower part 2, the Distance from lower part 2 to upper part 3 is conceivable.
- Lower part 2 and upper part 3 each have an inlet area 2a and 3a for cooling the die 1 serves.
- the outlet area is labeled 2d and 3d.
- the round wire 4 is made up of the lower part 2 and the upper part 3 existing die 1 gradually by pulling to a flat wire 5th reshaped.
- the fact that the die 1 is open to the sides is the cross section the flat wire is not rectangular, but the narrow sides are curved, which results from the fact that the deformation is actually a flattening or is a crushing process.
- Figure 2 shows a view of the die 1 against the direction of production. It is clear here recognizable that the die 1 shows no closed caliber.
- the die 1 shown in FIGS. 1 and 2 can be used as the last drawing stage in a continuously operating multiple drawing system are used, with several Matrices according to the invention can be arranged one behind the other in order to gradual deformation up to the final cross section of the flat wire 5 enable.
- the deformation can be accompanied by a reduction in cross-section, it
- the cross sections of round and flat wire can also be of the order of magnitude be equal.
- the die according to the invention can also be closed when rewinding from a first spool a second coil are used, the one running from the first coil Round wire is deformed into the flat wire, which is then wound onto the second coil becomes.
- the invention also has the decisive one Advantage on that the surfaces of the lower part 2 and the required for the deformation Upper part 3 can be polished much easier than with matrices closed caliber is possible.
