Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire drawing machine for drawing wires.

[0002]

2. Description of the Related Art Generally, a wire drawing machine mainly comprises a plurality of drawing dies and a capstan. Conventionally, as shown in FIG. 2, when wire drawing is performed by a wire drawing machine 7, wire is gradually drawn through a plurality of drawing dies and a capstan sequentially through a wire 3. In addition, the wire 3 that has exited the ascending die 2 is wound around the ascending capstan 1 several times to obtain a pulling force of the wire 3. Therefore it the wire 3 to be pulled out strongly up capstan 1, vibration 5 has occurred between the upstream die 2 and the upstream capstan 1.

[0003]

However, in the wire drawing machine 7 described above, since the wire 3 is pulled out by the upward capstan 1 with a strong force, the wire 3 between the upward die 2 and the upward capstan 1 is strong. Due to the tension, the wire 3 to be drawn vibrated. As a result, the wire 3 rubbing the uplink <br/> die 2 outlet or upstream capstan 1 inlet, and the wire 3 surface defects (Sure flaw) is generated, there is the appearance problem that a reduction in defect and electrical properties .

[0004] In the case of a high-speed wire drawing machine, the upstream die 2 is used.
Although a table called a mache was applied immediately after the exit, there was a problem that powder was accumulated on the mache, and the powder was attached to the wire 3 or was damaged.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and has as its object to provide a wire drawing machine capable of suppressing vibration of a wire and obtaining a good wire.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a wire drawing machine for drawing a wire through a drawing die and a capstan by using a wire between an ascending die and an ascending capstan. A vibration preventing roll is arranged so as to be in contact with the wire to be drawn.

[0007]

[Acting] between the upstream die and upstream capstan as described above, the vibration preventive roll is arranged in contact with the wire to drawing, to suppress the vibration of the wire between the upstream die and upstream capstan Can be.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic view of a main part showing an embodiment of the present invention. In the final part of a wire drawing machine 7, an upward die 2 for determining a finished outer diameter of a wire 3 and an upward capstan 1 for pulling out the wire 3 are shown. In the meantime, the anti-vibration roll 4 is in contact with the wire 3 to be drawn.
Is arranged.

Thus, the wire 3 gradually drawn through a plurality of drawing dies and a capstan is drawn to a desired outer diameter. Uphill die 2 and uphill capstan 1
Since the vibration preventing roll 4 is disposed in contact with the wire 3 to be drawn, the vibration of the wire 3 is suppressed even if the wire 3 is strongly pulled out by the up- capstan 1 so that the wire can be drawn well. Is performed.

In the case of a high-speed wire drawing machine, as a matter of course, the upstream die 2 and the upstream capstan 1
The vibration prevention roll 4 is disposed so as to be in contact with the wire 3 to be drawn. In the embodiment, the upstream die
2 and the number of upstream capstans 1 are plural.
However, it is of course also applicable to one case each.
Wear.

[0011]

As has been described above devised], between the upstream die and upstream <br/> capstan, the vibration preventive roll is arranged in contact with the wire being drawn, upstream die and uplink <br The vibration of the wire between the capstans can be suppressed. Therefore, the wire is not rubbed at the exit of the ascending die or at the entrance of the ascending capstan, so that a flaw (scratch) is generated on the surface of the wire, and a good wire is obtained without causing poor appearance and deterioration of electric characteristics. Obtainable.

[0012] In addition, the upstream die and above the case of high speed wire drawing machine
Since the anti-vibration roll is disposed between the capstan and the wire to be drawn so as to be in contact with the wire to be drawn, no muffler is used, so that a good wire can be obtained without fear of powder adhering to the wire.
