Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a welding wire charge in which a twisted welding wire is provided in a pail container with a predetermined loop and stacked and housed in a tubular shape.

[0002]

2. Description of the Related Art As a container for storing welding wires of 200 to 250 kg, the inner height of the container is approximately 800 mm and the inner diameter is approximately 5 mm.
A 00 mm outer cylinder pail container is most often used. As described later, in order to provide a means for preventing movement of the wire inside the container, the upper surface of the stored welding wire is stored in a state where there is a gap with the lid of the pail container.

On the other hand, one of the recent improvements in welding efficiency accompanying the increase in the size of a welded structure is to reduce the frequency of replacing the pail container when the welding wire stored in the pail container becomes empty. A large-capacity welding wire in a pail container containing 300 kg or more of stacked wires is demanded from various directions, and 300 to 350 kg of the welding wire is stacked and stored in an inner height of an outer cylinder of approximately 700 mm and an inner diameter of approximately 650 mm. Pail containers are used.

However, there are many cases in which a pail container having an outer cylinder inner diameter of about 650 mm cannot be installed due to the space of a welding device or a work place, and a large-capacity welding wire is stored in a pail container having an outer cylinder inner diameter of about 500 mm. A need has arisen for a pail container that has been replaced.

[0005] This welding wire is 700 to 1300 N
/ Mm ² , twisted within the range of its elastic limit, given a twist of, for example, 250 to 360 °, and stacked in a flower pattern with a predetermined loop diameter. Therefore, the welding wire has a property of acting to return the twist of the wire in the pail container, and has a property of bouncing in the axial direction of the pail container when the wire is free, so that the movement of the pail container during transportation and transportation. Vibration may cause winding disturbance of the wire. When subjected to welding in this state, the wire becomes entangled or entangled during welding, making welding impossible.

For this reason, conventionally, Japanese Utility Model Publication 3-11189.
Japanese Patent Publication No. 3-7329 and Japanese Utility Model Publication No. 3-7329 propose a technique of pressing a welding wire with a cushion material through an annular holding plate. 3, 4 and 5 show the actual fairness 3-7.
No. 329 discloses a large and small frame of a square short cylinder proposed in Japanese Patent Application Publication No. 329, and a cushion material using a rubber band that is stretched over the large frame and supports the small frame. 3A and 3B show a large frame, wherein FIG. 3A is a plan view and FIG. 3B is a front view. FIG. 4 shows a small frame, (a) is a plan view,
(B) is a front view. FIG. 5 shows a state in which the cushion material is loaded, (a) is a longitudinal sectional view, and (b) is FIG. 4 (a).
It is AA sectional drawing of.

As shown in FIGS. 3 (a) and 3 (b), the large cushion member 8 is a square cylinder inscribed in the outer cylinder 4 of the pail container so as to be positioned at a predetermined height of the pail container 3. ,
Made of foldable cardboard paper. The cushion member 8 of the large frame has locking portions 11 formed at appropriate intervals near the center of each side plate 10 near one of the upper and lower ends. Opening 1 at one end
There are two. The rubber band 9 passes through the inside of each corner 13, passes through the outside of each side plate 10, and extends to the cushion member 8 of the large frame via the locking portion 11.

The small frame 14 shown in FIGS. 4 (a) and 4 (b) is made of a collapsible cardboard paper which is a square tubular body which is fitted inside the large cushion material 8 and is fitted outside the inner cylinder 1. FIG. 5A shows a state in which the welding wire 6 is pressed using the cushion material 8 of the large frame and the cushion material of the small frame 14.
(B). A welding wire 6 with a twist is accommodated in a gap between the outer cylinder 4 of the pail container and the inner cylinder 1 fixed by an appropriate method to the bottom portion 5, and the holding plate 2 is placed on the welding wire 6. ing. Small frame 14 externally fitted to inner cylinder 1 on holding plate 2
And the cushion member 8 of the large frame with the rubber band 9 on the lower side is inscribed in the pail container 3 and placed on the small frame 14 so as to be fitted outside. Then, the large cushion material 8
While holding down, the lid 7 of the pail container is fixed, and the pressing of the welding wire 6 is completed.

Incidentally, the inner diameter of the outer cylinder for storing 250 kg or less is generally about 500 mm, and the height inside the container is about 800 m.
When 300 kg of welding wire is stacked and stored in a m container, the gap between the holding plate on the upper surface of the stacked welding wire and the lid of the pail container is narrow, or the pile is stacked up to the inner height of the pail container. become. Therefore, the cushion member using the above-described square short cylinder large and small frames and a rubber band that is stretched over the large frame and supports the small frame is placed between the holding plate on the upper surface of the stored welding wire and the lid of the pail container. It cannot be inserted and cannot hold down the welding wire. Therefore, the pail container in which the welding wires are stacked and stored cannot be moved or transported.

[0010]

SUMMARY OF THE INVENTION The present invention relates to a method of manufacturing a pail container having an inner height of about 800 mm and an inner diameter of about 500 mm, in which a large volume of welding wires is stored in a stacked manner. There is a gap, and the welding wire stacked and stored with the cushion material can be held down, the pail container can be moved and transported, and the space for the welding equipment and work area can be saved. It is an object of the present invention to provide a charge of welding wire without tangling or the like.

[0011]

SUMMARY OF THE INVENTION The gist of the present invention is that the height inside the container constituting the pail container is approximately 800 mm and the inner diameter is approximately 5 mm.
In a loading of a torsion welding wire stacked and housed in a tubular shape between a 00 mm outer cylinder and an inner cylinder erected at the bottom of the pail container, the torsion welding wire is a wire from the bottom of the pail container. The wire stacking density ρ (g / cm ³ ) with respect to the wire diameter d (mm) in the pile container volume w (cm ³ ) up to the stacking height h (cm) is 2.44-0.20.
d, and preferably 2.64 to 0.20 d or less.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION The present inventors set a loop diameter and a loop pitch between an outer cylinder having an inner height of a pail container of 800 mm and an inner diameter of 500 mm and an inner cylinder provided upright at the bottom of the pail container. Instead, 300 kg of solid wires for welding (JIS Z3312 YGW11) having various wire diameters were loaded. It was investigated whether there is a gap between the pressing plate on the upper surface of the welding wire after loading and the lid, and it is possible to hold the welding wires stacked and stored with the cushioning material shown in FIGS. A gap of 50 mm or more is required to insert the cushioning material into the gap between the lid and the lid on the upper surface of the stacked and stored welding wires. Further, in the case where the upper surface of the welding wire was able to be held down by the cushion material, the welding device was used to apply 100 kg of the welding wire at a speed of 10 m / min.
Was taken out, and the presence or absence of entanglement or tangling at the time of taking out was examined.

Only some loops are shown. FIG.

FIG. 2B shows that the loop diameter D and the loop pitch P are small and
This is the case where the ear stacking density is high. Note that the actual loop

It is about 0 mm.

In the drawing, the wire stacking density ρ with respect to the wire diameter d in the pile container volume w from the solid line A to the wire stacking height h from the bottom of the pail container is 2.44.
If it is −0.20 d (g / cm ³ ) or more, there is a gap between the lid and the lid on the upper surface of the stacked welding wires, and the welding wires can be pressed by the cushion material, and the pail container can be moved or transported. This makes it possible to save space in the welding device and the working place, and there is no problem such as tangling or tangling when the welding wire is taken out. According to the above equation wire stacking density, when the wire diameter 0.9mm 2.26 g / cm ³ or more, although it comes to 2.16 g / cm ³ or more when 1.4 mm, the conventional wire diameter 0.9mm 2.12
g / cm ^3, those was 1.90 g / cm ³ about the time of 1.4 mm. This conventional condition has been customarily and generally employed without the intention of increasing the wire stacking density as much as possible.

[0015] The wire stacking density ρ with respect to the wire diameter d in the volume w of the pail container from the bottom of the pail container to the wire stacking height h is less than the solid line A, ie, 2.44-0.20d.
If it is less than (g / cm ³ ), the gap between the holding plate and the lid on the upper surface of the stacked welding wires is narrow, or the welding wires are stacked up to the inner surface height of the pail container, and the cushion material is removed. It cannot be inserted between the lid of the holding plate on the surface of the welding wire and cannot hold the welding wire.

In the drawing, the dashed line B, that is, the wire stacking density ρ with respect to the wire diameter d in the pail container volume w from the bottom of the pail container to the wire stacking height h is 2.64-0.
If it exceeds 20 d (g / cm ³ ), the stored welding wire can be held down by the cushioning material, and the pail container can be moved or transported. However, the loop pitch is small when the welding wire is taken out. Loops are simultaneously taken out and entanglement may occur. Further, since the loop diameter of the stacked and stored welding wires is small, the wires are plastically deformed at the time of loading or moving or transporting the wires, causing a bending habit, and the beads meander during welding.

[0017]

EXAMPLE A solid wire for welding of various wire diameters d (JIS Z33) is provided between an outer cylinder of a pail container having an outer cylinder inner diameter of 500 mm and an inner height of 800 mm and an inner cylinder erected at the bottom.
12 YGW11) was charged in an amount of 300 kg. At this time, the loop diameter and the loop pitch were adjusted to change the wire stacking density ρ in the pile volume w up to the wire stacking height h. After loading, place a holding plate on the top surface of the welding wire and fix the lid of the pail container by holding the welding wire stacked and stored with cushioning material for those with a gap of 50 mm or more between the holding plate and the lid. did.

The test example in which the welding wires stacked and stored by the cushion material were pressed was 500 km on a truck.
After the transportation, 100 kg of the welding wire was taken out at a speed of 10 m / min using a welding device, and the presence or absence of entanglement or entanglement was examined. In addition, welding with a welding length of 1500 mm was separately performed by a bead-on-plate test, and the presence or absence of bead meandering was also investigated. Table 1 shows the results.

[0019]

[Table 1]

Test No. 1 in Table 1 1 to 4 are examples of the present invention, and test Nos. 5 to 8 are comparative examples. Test N which is an example of the present invention
o. 1 to No. The wire stacking density ρ for the wire diameter d in the pile container volume w from the bottom of the pail container to the wire stacking height h is 2.44 to 0.20d to 2.4.
Within a range of 64-0.20 d (g / cm ³ ), a gap of 50 m is provided between the lid and the holding plate on the upper surface of the welding wire stored and stored.
m or more, the welding wire could be held down by the cushioning material, and there was no entanglement or entanglement when the welding wire was taken out after the movement and transportation of the pail container.

Test No. in the comparative examples. 5 and test no. 7
Since the wire stacking density ρ with respect to the wire diameter d in the pail container volume w from the bottom of the pail container to the wire stacking height h exceeded 2.64−0.20 d (g / cm ³ ), Although the stored welding wire was able to be held down, the loop pitch was small when the welding wire was taken out after the movement and transportation of the pail container, so that multiple loops were taken out simultaneously and entanglement and entanglement occurred once each. . In addition, since the loop diameter of the stacked and stored welding wires was small, the welding wires were plastically deformed when the wires were loaded or moved or transported, causing a bending habit, and the beads were partially meandered in the welding test.

Test No. 6 and test no. 8, since the wire stacking density ρ with respect to the wire diameter d in the pail container volume w from the bottom of the pail container to the wire stacking height h is less than 2.44-0.20 d (g / cm ³ ),
The gap between the lid and the lid on the upper surface of the stacked welding wires was narrow, and the cushion material could not be inserted between the lid and the lid on the surface of the welding wire, so that the welding wire could not be pressed. Therefore, the removal of the welding wire after transportation and the welding test were stopped.

[0023]

As described above in detail, according to the loading of the welding wire of the present invention, even when the welding wire is stored in a large volume in a bail container having an internal height of about 800 mm and an inner diameter of about 500 mm. There is a gap between the holding plate on the top of the welding wire and the lid, so that the welding wire stacked and stored with cushioning material can be held, and the pail container can be moved and transported, saving space in the welding equipment and work locations. Entanglement, entanglement and bead meandering do not occur when the welding wire is taken out.
