Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a container wire for welding.

[0002]

2. Description of the Related Art Due to the aging of welders and the like, there is a demand for lightweight wires (less than 10 kg), and those wound in conventional plastic pools, etc.
From the viewpoint of industrial waste generation and resource recovery, its disposal has become a social problem.

If these problems can be solved, it can be applied in a wide range, such as welding wires having to be carried manually, welding at high places and narrow places, and the like.

Conventionally, a winding body S as shown in FIGS. 1 and 2 has been widely used as a storage body for a lightweight welding wire. That is, the winding body S is obtained by winding the welding wire W on the body portion 1a of the bobbin 1 made of plastic, iron, fiber board or the like, and the winding start end on the winding body portion 1a.
After the winding end is locked in the groove, hole, etc. of the flange portion 1b, the whole is covered with a moisture-proof material, and then stored in a corrugated cardboard 3 or the like. FIG. 2 shows an example of the reel 1 and a state in which the welding wire W is wound around the reel 1.

In the case of these storage methods, it is always necessary to consider disposal of waste such as plastic. On the other hand, as a coil winding welding wire, a wire having a diameter of 2.0 mmφ or more has been put into practical use, but a wire having a diameter of less than 2.0 mmφ has not been put into practical use because the coil is distorted and entangled.

In view of such circumstances, the present invention is to provide a welding container-enclosed wire which is lighter in weight than conventional ones and which is housed so as not to cause trouble during use. It is intended.

[0007]

As a result of earnest research for solving the above-mentioned problems, the inventor of the present invention has found that wires having a diameter of 1.6 mm or less are normally maintained at the time of wire straightness at the time of welding and prevent loosening at the time of feeding. For convenience of setting to the welding and feeding device, it was wound on a spool (spool) made of plastic or the like, but without these reels, a cylinder having an inner cylinder, an outer cylinder and a bottom plate By storing in a container in the prescribed manner,
The present invention has been completed based on the finding that the wire can be restrained and packaged.

That is, according to the present invention, the outer cylinder inner wall diameter is 100.
Height of ~ 300mmφ with inner cylinder and bottom plate 20 ~ 200
1 to 10 kg of thin wire of 0.6 to 1.6 mmφ so that the inner diameter of coil is 50 to 250 mmφ in a cylindrical container of mm.
The gist is a wire in a welding container, which is characterized by being stored.

The present invention will be described in more detail below with reference to the drawings.

The reason for limiting the wire diameter, the coil weight, the shape and size of the container, etc. in the present invention is as follows.

Wire diameter: 0.6 to 1.6 mmφ The wire diameter of the thin wire targeted by the present invention is
The range is from 0.6 to 1.6 mmφ. The loosening, entanglement, and the like during use (welding) are a problem with thin wires, especially those with a diameter of 1.6 mm or less. Therefore, the upper limit of the wire diameter is 1.6 mmφ. On the other hand, the lower limit of the wire diameter is set to 0.6 mmφ as a value that can be produced on an industrial basis.

Weight of one coil: 1 to 10 kg If the weight of one coil is less than 1 kg, the weight is too small and the frequency of coil replacement is too high, which is not practical. On the other hand, 10
If it exceeds kg, the weight becomes too large, and as with the conventional one, the manual handling becomes a problem. Regarding the coil unit weight, in the case of a thin wire, if it exceeds 10 kg,
Frequent wire entanglement and entanglement, wire feedability,
If it is too strong, it will lead to defects in the weld. Therefore, the unit weight of the coil is 1 kg or more and 10 kg or less.

Coil inner diameter: 50 to 250 mmφ In order to obtain good wire feedability and straightness, the coil inner diameter (see FIG. 3a) must be 50 mmφ or more.
However, if the inner diameter of the coil exceeds 250 mmφ, the winding shape of the coil itself becomes large, and the size cannot be reduced, which is not preferable.
Therefore, the inner diameter of the coil is set to 50 mmφ or more and 250 mmφ or less.

Outer cylinder inner wall diameter of the cylindrical container: 100 to 300
If the mmφ outer cylinder inner wall diameter (see b in Fig. 3) is too small, the wire stacking height becomes large compared to the wire stacking width, and the change in the drawing conditions (height direction) becomes large as the wire is used. Tangles are likely to occur. Therefore, the inner wall diameter is 100 mm or more. However, if the inner wall diameter exceeds 300 mm, the coil shape becomes large and the size cannot be reduced. Therefore, the inner wall diameter of the outer cylinder is set to 100 mm or more and 300 mm or less.

Cylindrical container height: 20 to 200 mm If the height of the cylindrical container (see H in FIG. 3) is too small, the coil shape becomes large and the size cannot be reduced. Therefore, the height should be 20 mm or more. However, if the height exceeds 200 mm, the wire stack height becomes larger than the wire stack width,
As the wire is used, the pull-out condition (height direction) changes greatly, and the wire is likely to be entangled. Therefore, the height H of the cylindrical container is set to 20 mm or more and 200 mm or less.

As described above, the cylindrical container of the present invention is provided with the outer cylinder having a predetermined size and shape.
The present invention is characterized in that an inner cylinder is provided in the cylindrical container. For example, as shown in FIG. 3 as an example, the cylindrical container 4 has an outer cylinder 5, an inner cylinder 6 and a bottom portion 7, and the inner cylinder 6 is
It is hollow and provided in the center of the cylindrical container 4. In that case,
When the wire is used, the hollow portion of the inner cylinder 6 can be fitted into a cylindrical jig (a cylindrical portion provided in the center of the wire support base) (hatched portion in the figure) provided in the wire feeding device. Is preferred.

The cylindrical container may be formed of an appropriate material. For example, an outer cylinder made of plastic or a waterproof board,
The inner cylinder and the bottom are made into a one-body molding die. The height of the inner cylinder is preferably equal to or lower than the height of the outer cylinder. Further, as shown in FIG. 4, a hole 6 ′ may be opened in the upper part of the inner cylinder 6 so that the cylindrical portion (dotted line in the figure) of the wire support base of the wire feeding device can be inserted therethrough. . It is also possible to seal the upper surface of the container with a rust preventive film or the like, remove the rust preventive film at the time of use, and set the wire feeder.

FIGS. 5 to 8 show an example of the structure of the welding container-containing wire of the present invention.

FIG. 5 shows a wire W in a container 4 in which an outer cylinder 5, a bottom plate 7 and an inner cylinder 6 are integrally molded with a plastic or waterproof board.
The rust preventive film 8 is heat-sealed or glued on the upper surface in order to prevent rust of the wire during storage. Furthermore, the inner cylinder inner wall and the inner cylinder outer wall are formed in a tapered shape that spreads upward, and the taper of the inner cylinder 6 allows the wire to be pulled out more smoothly. Further, since the position of the wire W is regulated by the outer cylinder 5 and the inner cylinder 6, it is possible to prevent the wire from being disturbed during transportation, drawing of the wire, or the like. Further, by tapering the inner cylinder 6 and the outer cylinder 5,
The wire can be smoothly dropped into the container when the wire is manufactured.

FIG. 6 shows a configuration in which the bottom plate (disc) 7 and the inner cylinder 6 of the container 4 are made of plastic or cardboard, and the whole is covered with a resin film 9 such as a waterproof (moisture-proof) shrink film. Therefore, the outer cylinder 5 is made of a film. According to this structure, the wire W is regulated by the film 9 (outer cylinder) and the inner cylinder 6 such as a plastic plate, and the regulation of the wire is more reliable than in the case of the structure of FIG. Also, the manufacturing cost can be reduced.

FIG. 7 shows an example in which the entire container is covered with a rust preventive film 8. The inner cylinder, the outer cylinder and the bottom are made of a rust preventive film, and the rust preventive film 8 is heat-sealed on the upper surface. is there. According to this structure, the manufacturing cost is low, and the regulation of the wire is sure. If a disc-shaped cardboard or a plastic plate having a certain degree of rigidity is used instead of the rust-proof film heat-sealed on the upper surface, the rigidity as a container wire increases and the handling becomes easy. Become.

As a modification of the configuration shown in FIG. 7,
As shown in FIG. 8, the entire wire may be covered with the anticorrosion film 8. In this case, the top and bottom of the cylindrical space will be open if you do not cover it with anticorrosion film.
Since this point is different from that of FIG. 7, it can be set as it is on the wire feeding device.

Next, examples of the present invention will be described.

[Table 1] Shown in. In FIG. 5, the inner wall diameter of the outer cylinder is the outer wall inner wall diameter at the bottom of the container, although the inner wall diameter varies depending on the measurement location because of the taper. From Table 1, all of the examples of the present invention were good in wire feedability and wire straightness.

It goes without saying that the present invention can be applied to both solid wires and flux-cored wires.
