Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a novel bending device that can be installed in a minimum space when bending drawn wire in multiple directions.

(Prior Art) Wire multidirectional bending devices are commonly used for the purpose of straightening, mechanical descaling, or repeated bending. In many cases, multidirectional bending equipment is installed at the entrance, exit, or inside of a wire drawing machine, cold forging machine, heating furnace, plating equipment, or the like. FIG. 6 shows an example of installation at the entrance, middle, and exit of a wire drawing machine. 8 is a wire feeding device, 9 is a wire drawing machine, 10 is a winding machine,
11 is a bending device, and 12 is a wire.

Many of the multi-directional bending machines are manufactured by the Japanese Patent Publication Publication No. 60-26805.
This is a series of rollers arranged in series. Some have rollers arranged three-dimensionally,
There is no arrangement similar to that of the present invention.

(Problems that the invention aims to solve) With the conventional roller arrangement, a long space is required to install the bending device, and when installing it in existing equipment, large-scale modification is required. Cheap. Especially when relatively gentle bending is required, the roller diameter will be large.
It is easy to find it difficult to secure the necessary space.

The object of the present invention is to improve conventional bending rollers in order to eliminate the above-mentioned drawbacks. In order to achieve this purpose, this invention
The novel feature is that the rollers are arranged in a polyhedral shape.

(Means for Solving the Problems) The present invention is a multidirectional bending device characterized in that rollers are arranged three-dimensionally so that the surfaces including the rotating surfaces of the rollers constitute a polyhedron.

This invention will be explained below with reference to two specific examples shown in the drawings. Figures 1 and 2 show examples in which the rollers are arranged so that the surfaces including the rotating surfaces of the rollers form an octagonal prism, and the rollers 1-1, 1-2,...
This is an example in which the rollers 1-8 are arranged along each side of the octagonal column 4, and FIGS. 3 and 4 show the rollers 1-1,...1-4.
This is an example in which the square prisms 5 are arranged along each side of the square prism 5.

In addition to the exemplified examples, they may be arranged in any polyhedral shape such as a triangular prism, a pentagonal prism, a hexagonal prism, or a hexahedron.
Furthermore, it is also possible to provide auxiliary rollers 7 outside or inside the polyhedron. FIG. 5 shows an example in which an auxiliary roller 7 is provided to change the introduction direction 2 and removal direction 3 of the wire 12.

In many cases, the multidirectional bending device as described above is installed at the entrance, exit, or inside of a wire drawing machine, cold forging machine, heating furnace, plating device, or the like.

When the multidirectional bending device is used in combination with other processing devices, it is not necessary to attach a special drive device to drive the rotating shaft 6 of the roller, but if the processing force is particularly large, a drive device may be attached. can.

(Function) To explain the case where the bending device of the present invention shown in FIGS. 1 and 2 is used as a typical example, first, the wire is introduced from direction 2 in the rotating surface of the roller 1-1, and then Rollers 1-2,1 on adjacent surfaces
-3, . . . , wire 12 is hung from 1-8.
The wire 12 is taken out in direction 3 in the plane of rotation of the final roller 1-8.

Therefore, by using this device, the wire introduction and removal directions can be easily set to any direction. Of course, the introduction direction 2 and the extraction direction 3 can also be parallel as illustrated in FIG.

(Effects of the invention) Since the present invention is a bending device having the above-mentioned configuration, it can be made into an extremely compact device, and 1. It can be installed in a narrow space.

2. Can be easily installed on existing equipment.
