Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire straightening device, and more particularly to a device for straightening and aligning wires such as electric wires.

In conventional wire rod straightening devices, in order to straighten the wire, it is necessary to forcibly meander the wire to be processed between a large number of straightening rollers, and even one wire rod straightening system (straightening block) requires a considerable number of installed rollers. In order to straighten multiple wire rods at the same time, multiple wire straightening systems (straightening blocks) must be installed, and the number of required rollers is quite large. The overall space occupied was too large, making it inconvenient to implement. In addition, as a measure to reduce the number of straightening rollers installed, a method has been considered in which a long cylindrical roller is used as the straightening roller and multiple wire rods are simultaneously straightened using the same long cylindrical roller. It is difficult to configure the straightening rollers for both the horizontal wire straightening system and the vertical wire straightening system as long cylindrical rollers, and to straighten the wire horizontally and vertically in one continuous process. It must be an independent process, and furthermore, in this method, the plurality of wire rods to be processed tend to disperse and scatter toward the end of the long tube roller.
It is difficult to maintain and process a plurality of wires in an aligned manner, making it unsuitable for practical use.

Therefore, in the installation of the first wire rod straightening system and the other wire rod straightening system, the straightening directions thereof are arranged in cross directions with an angle difference of 90 degrees from each other with respect to the axis in the wire rod advancing direction. 1 is a horizontal wire straightening system, and the other is a vertical wire straightening system. Provided is a wire straightening device in which a torsional displacement of 90° is applied between the straightening systems, and the straightening rollers in each wire straightening system are configured as truncated conical rollers having opposite tapers on one side and the other side of the wire advancing path. death,
The object of the present invention is to eliminate the above-mentioned deficiencies of the prior art in straightening a plurality of wire rods.

Referring to the drawings, the conventional single wire straightening device shown in FIG. roller 3
The wire rod 1 to be processed is supplied from the introduction side C and meandered between the straightening rollers 2 of the vertical wire rod straightening system A, and then the horizontal wire rod straightening system In this conventional wire rod straightening device, the wire rods meander between the straightening rollers 3 of B and are forcibly driven to the delivery side D to remove irregular curved deformations in the vertical and horizontal directions. In order to perform the straightening process simultaneously, a plurality of single wire straightening devices including a vertical wire straightening system A consisting of a straightening roller 2 and a horizontal wire straightening system B consisting of a straightening roller 3 are installed in the embodiment shown in FIG. The wire rods 1 to be processed from the plurality of single wire straightening devices need to be guided in a collective manner to the delivery side D by an arbitrary number of feed rollers 4. The number of rollers required to be installed is considerable, and the area occupied by the straightening device is also quite large, resulting in a lack of implementation efficiency. As a conventional wire straightening device, as shown in FIG. 3, a long cylindrical roller 5 horizontally supports the straightening roller of the vertical wire straightening system A', and the long cylindrical roller 5 straightens the vertical wire. There is also a configuration in which straightening of multiple wires in system A' is processed at once to reduce the number of straightening rollers installed in the vertical straightening system and to reduce the installation surface area of the device, but even in this configuration, each single wire The horizontal straightening must be performed by straightening system B, which is a separate and independent horizontal wire straightening system and consists of an arbitrary number of straightening rollers 3;
Coupled with the need to install the feed roller 4, the second
It had the same drawbacks as the device shown in the figure. Further, the long cylindrical roller 5 has a disadvantage in that the plurality of wire rods processed between the rollers 5 tend to disperse toward the ends of the roller.

Therefore, as shown in FIG. 4, the wire straightening device of the present invention has an optional number of sanderch guide rollers 6, which are a pair of long cylindrical rollers sandwiching the wire progressing path, slightly axially aligned with the outer shape of the guide rollers 6. A straightening roller 7, which is a tapered truncated conical roller, is arranged so that its rotational axis is parallel to the rotational axis of the sanderch guide roller,
The straightening rollers on one side and the straightening rollers on the other side are arranged so that the straightening rollers on one side and the straightening rollers on the other side of the wire rod advancing path have tapered directions of their truncated cones in opposite directions. Unit wire rod straightening systems (A″, B″) are arranged alternately across the wire rod advancing path, and the two unit wire rod straightening systems configured as described above are mutually connected to the sandwich guide rollers 6a and 6b. Therefore, the rollers are installed adjacently and consecutively and symmetrically on the same wire advancement path, and with respect to the roller rotation axis of one wire rod straightening system,
The roller rotation axes of the other wire rod straightening system are arranged so as to be orthogonal to each other, forming a horizontal wire rod straightening system B'' and a vertical wire rod straightening system A'', which are used to straighten multiple wire rods aligned in a line. A ribbon-shaped wire bundle 8 consisting of
A truncated conical roller 7b, which is supplied to the wire rod B'' and is installed on the right side of the wire rod advancing path and is tapered so that the diameter increases upward, and a conical roller 7b that is installed on the left side of the wire rod advancing path. A truncated conical roller 7 which is a trapezoidal roller and tapers so that the diameter becomes thicker toward the bottom.
It is made to meander between the straightening rollers b′ and
As a result, the bend in the horizontal direction is corrected, and the wire is sent out via the sanderch guide roller 6b to the sanderch guide roller 6a of the vertical wire straightening system A'', where the vertical wire rod straightening system
The rotation axis of each roller of A″ is a horizontal wire straightening system.
The wire bundle 8 is introduced between the sanderch guide rollers 6a after undergoing a 90° twisting displacement at the point E. That is, the horizontal wire straightening system B'' Within the vertical wire straightening system A'', the multiple wire bundle 8, which supports and contains each single wire in a line in the vertical direction, is processed by being supported in a line in the horizontal direction due to twisting displacement at the point E. However, each single wire in the wire bundle 8 is reversed by the traction drive on the delivery side D, twisted by 90 degrees due to its physical properties, and introduced into the vertical wire straightening system A'' horizontally. Each single line correction in both vertical directions is achieved. That is, the wire bundle 8, whose bends on both the left and right sides have been corrected by the horizontal wire straightening system B'', is set in a twisted state at the point E, so that the wire bundle 8 is bent at 90 degrees by the vertical wire straightening system A''. The process proceeds so that the different bends on both the upper and lower sides are corrected. The wire bundle 8 supplied to the sandwich guide roller 6a of the vertical wire straightening system A'' is a truncated conical roller located below the wire advancing path, and is tapered so that the diameter increases toward the right side in the advancing direction. The wire is made to meander between a straightening roller which is a truncated conical roller 7a and a truncated conical roller 7a' which is a truncated conical roller located above the wire traveling path and is tapered so that the diameter becomes thicker toward the left in the direction of wire travel. The curvature in the vertical direction is corrected and the truncated conical roller is forcibly driven to the delivery side D.As shown in FIG. structure 10
It is also possible to implement this roller structure in combination with the disclosed truncated conical roller 7.

In the wire straightening device of the present invention, the straightening roller for processing a plurality of wires at once is constituted by truncated conical rollers having mutually opposite tapers across the wire advancing path. In this case, the plurality of wire rods to be processed tend to move and gather toward the center of the roller, and the dispersion and scattering phenomenon of wire rods toward the end of the roller in conventional long cylindrical rollers is prevented. Coupled with the torsional displacement of ゜, in the straightening process of multiple wire rods, from the initial stage to the final stage of the straightening process, multiple wire rods are collectively treated as one wire bundle, and only in one continuous processing process. It eliminates the drawbacks of the conventional equipment mentioned above, the work is simple, the number of rollers is small, it is economical, and the area it occupies is extremely small, so it exhibits remarkable technical effects. be.
