Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous annealing winding device for continuously annealing and winding a metallic wire.

[0002]

2. Description of the Related Art A wire made of a metal material is generally classified into a hard material and a soft material. In the production of a soft material, there are a case where annealing is performed after plastic working and a case where an annealing device is installed in a tandem in a wire drawing device or a rolling device and annealing is performed continuously. In recent years, particularly in pursuit of productivity, a continuous wire drawing or rolling device equipped with a wire drawing / rolling device and a tandem annealing device has been used for the production of a soft wire rod having a small sectional area of approximately 310 mm ² or less.

FIG. 2 shows the configuration of a general continuous drawing or continuous rolling apparatus. An annealing device 2, a dancer device 3, and a winding device 4 are installed in a drawing or rolling device 1 in tandem. The wire drawing or rolling device 1 performs plastic working on a wire. The annealing device 2 includes a first sheave 5, a second sheave 6, and a third sheave 7, and the plastically worked wire 12 is wound around these sheaves 5 to 7, and the electric resistance of the wire 12 is used. The wire 12 is annealed by heating the wire using the sheave as an electrode. Winding device 4
Winds the wire 12 ′ annealed by the dancer device 3 under the thickening control by the bobbin 11. 10 is a traverser.

[0004] As shown in FIG.
A fixed-side pulley 8 and a movable-side pulley 9 are provided. A wire 12 ′ is wound between the pulleys 8, 9, and the movement of the movable-side pulley 9 with respect to the fixed-side pulley 8 is adjusted to perform winding thickening control. Like that.

[0005] On the other hand, there are various characteristics required for a wire rod as a product, but in certain applications, there is an increasing demand for uniformity of the linearity of the wire rod. In the production of hard materials, continuous annealing may be performed, which is called so-called strain relief annealing. At that time, a continuous drawing or continuous rolling device in which an annealing device is installed in tandem is used as in the case of the soft material.

[0006]

In the conventional continuous wire drawing / rolling apparatus, improvement of the apparatus for improving the linearity of the wire rod and improvement of its use have been made. As an example, adjustment of the peripheral speed of a pulley in a annealing apparatus, execution of strain relief annealing, and the like can be cited. In particular, in the strain relief annealing, there is also a case where the tension applying annealing is performed to improve the effect by increasing the weight of the dancer pulley. Furthermore, there has been a device for increasing the speed increase ratio of the peripheral speed of the pulley, increasing the tension in the annealing device, and improving the linearity.

[0007] However, in the positive tension annealing, the deformation of the bobbin caused by the increase in the tension of the wire is promoted, and when the speed increase ratio of the pulley peripheral speed is increased, the quality of the wire surface deteriorates due to the increase in slip. Problem arises.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a continuous annealing and winding apparatus for a wire, which is provided with a mechanism capable of independently adjusting the tension in the winding apparatus while positively applying tension to the wire in the annealing apparatus. It is in.

[0009]

Means provided by the present invention: a continuous annealing and winding apparatus for a wire rod includes an annealing apparatus and a dancer apparatus installed in a tandem with a rolling or drawing apparatus and an annealing apparatus for a winding apparatus. A tension pulley for generating tension in the wire is installed between the wire and the dancer device to add tension to the annealed wire.

The tension pulley may comprise a driving tension pulley and a driven tension pulley. As the drive source of the drive-side tension pulley, a drive motor of a rolling device or a wire drawing device may be used, or an independent power source, for example, a motor may be used.

[0011]

FIG. 1 shows only a tension pulley and a dancer device of a continuous annealing and winding apparatus for a wire rod according to the present invention. For the rolling device or the drawing device, the annealing device, and the winding device for performing the plastic working on the wire rod, see FIG. 2 and the above description related thereto.

The tension pulley is composed of a driving-side tension pulley 13 and a driven-side tension pulley 14. The driving-side tension pulley 13 uses the shaft of the fixed-side dancer pulley 8, and is parallel to the fixed-side dancer pulley 8. Provided. Driven tension pulley 14
Is a position supported by an independent shaft and does not hinder the movement of the movable dancer pulley 9,
3 is provided.

The wire 1 annealed by the annealing device 2 (FIG. 2)
2 'is first wound around the driving-side tension pulley 13 and the driven-side tension pulley 14, and then wound around the dancer pulleys 8 and 9. The drive-side tension pulley 13 is linked to a separately provided power source, for example, a motor (not shown) via a sprocket (or pulley) 15, a drive belt or a chain 16, and is driven by the operation of the motor.

By making the peripheral speed of the driving-side tension pulley 13 faster than the peripheral speed of the third sheave 7 (FIG. 2) in the annealing device 2, tension is applied to the wire 12 ', and the strain after the strain relief annealing or the annealing is performed. The linearity is improved.

As the power source, in addition to the independent motor as described above, a drive motor of a drawing or rolling device may be used via belts.

Since the ratio between the peripheral speed of the driving-side tension pulley and the peripheral speed of the third sheave in the annealing device due to the operation of the power source can be arbitrarily changed, the applied tension to the wire is changed by the speed ratio.

The number of tension pulleys need not always be two on the drive side and the independent side, and may be one on the drive side.

[0018]

As described above, according to the present invention, continuous annealing of a wire rod provided with a mechanism capable of independently adjusting the tension in the winding apparatus while positively applying tension to the wire rod in the annealing apparatus. The intended task of providing a winding device; the object can be achieved. According to the apparatus of the present invention, the tension of the passing wire rod in the annealing apparatus can be arbitrarily changed by the tension pulley irrespective of the winding tension at the bobbin, so that there is no deterioration in surface quality or deformation of the bobbin, It is possible to manufacture a wire excellent in linearity, and it can be said that the effect is great.
