Definitions
- the present invention relates to a welding wire charge in which welding wires such as a solid wire and a flux-cored wire are loaded and stored in a loop shape by twisting in a bail container.
- Pail containers are generally used as welding wire containers with a large capacity of 200 to 350 kg, but the contained welding wires are twisted within the elastic limit, for example, 27 per wire loop. It is housed in a bail container with a twist of 0 to 360 °. Since the welding wire has a built-in force to untwist the wire inside the bail container and tends to bounce in the axial direction of the bail container when the wire is released, the welding wire is entangled when the wire is removed. However, tangling occurs remarkably. For this reason, for example, as described in Japanese Patent Publication No. 59-8474, a ring-shaped holding plate is placed on a loop body in which a welding wire is stacked in a bail container.
- FIG. 5 is a cross-sectional view of a state in which the welding wire stored in the bail container is taken out of the loading of the welding wire described in Japanese Patent Publication No. 59-8474.
- the welding wire is twisted and stored in a loop.
- the welding wire 5 forms a cylindrical cavity 4 formed by the loop body 2.
- An annular holding plate 8 is mounted on the upper part of the loop body 2 to prevent the welding wire from jumping up.
- the inner diameter of the annular holding plate is made slightly smaller than the inner diameter of the loop as a necessary and sufficient dimension for holding the loop.
- the inner diameter of a pile container is generally 50 mm or 65 mm, but the inner diameter of the loop is about 34 to 46 mm, whereas the annular holder
- the plate used has an inner diameter of about 230 to 350 mm.
- FIG. 6 is a plan view of a portion of the bail container of FIG. 5, particularly showing several turns of the welding wire at the top of the loop 2. Since the take-out position of the welding wire 5 is rotating along the inner circumferential end 9 of the annular holding plate 8, the welding wire 5 is always in almost parallel contact with the next loop 10. In addition, it is removed while moving along the inner circumferential end 9 of the annular holding plate 8.
- the present invention has no entanglement or entanglement of the welding wire even when the welding wire is taken out of the bail container at a high speed, or when the rigidity of the wire is large, and the welding wire is bent.
- An object of the present invention is to provide a charge of a welding wire, which enables smooth feeding to a weld without causing a habit. That is, the present invention relates to a welding wire loaded in which a cylindrical hollow is formed in a central portion of a bail container and the welding wire is twisted by being twisted and stored in a loop shape.
- a wire holding member having a loop body holding portion for holding the loop body and a wire guide portion having a diameter of a hole at the center and through which a welding wire passes is set to 180 mm or less, is disposed at an upper portion of the loop body. It is assumed that.
- the breaking strength of the welding wire is T (kgf)
- the diameter of the hole through which the welding wire of the wire guide passes is 0.55 T + 10 (mm) or more.
- the weight of the wire pressing member is W (g)
- the breaking strength of the welding wire is T (kgf)
- the ratio W / T is in the range of 4 to 32.
- FIG. 1 is a cross-sectional view of a state in which the welding wire stored in the bail container is taken out of the loaded welding wire of the present invention
- FIG. 2 is a plan view of a part of FIG. 1, and FIG. It is a partially enlarged view.
- FIG. 4 is a plan view showing another example of the wire pressing member according to the present invention.
- FIG. 5 is a cross-sectional view of a state in which a welding wire stored in a bail container is taken out of a conventional welding wire charge
- FIG. 6 is a plan view of a portion-in FIG. BEST MODE FOR CARRYING OUT THE INVENTION
- FIG. 1 shows an example of the charge of the welding wire of the present invention.
- FIG. 1 is a cross-sectional view showing a state in which a wire stored in a bail container is taken out. Are stored in a loop.
- a disc-shaped flat holding plate 3 is placed on the upper end of the loop body 2 to prevent the wire from jumping up.
- the disc-shaped flat holding plate 3 of the present invention is provided with a wire extraction hole 6 at the center of the holding plate. That is, the holding plate 3 in the present invention has not only the function of simply holding the loop body 2 but also the function of regulating the take-out route of the welding wire to the center thereof.
- Reference numeral 1 2 denotes a cord member for preventing the welding wire 5 from jumping out of the gap between the wall in the bail container 1 and the holding plate 3.
- the same effect can be obtained by providing the pressing plate 3 with an elastic member that comes into contact with the inner wall of the pail container 1 instead of the string member.
- FIG. 2 is a plan view of a portion of the bail container of FIG. 1 and specifically illustrates the top few turns of the loop body 2 of welding wire.
- FIG. 3 is a partially enlarged view of FIG.
- the wire take-out hole 6 is provided in the center of the disc-shaped flat holding plate 3, so that the loop immediately before being taken out expands until it comes into contact with the inner wall of the bail container due to the rigidity of the torsion welding wire. It will be in a state where For this reason, the welding wire is pulled out from the state in which it comes into contact with the inner wall of the bail container toward the wire withdrawal hole 6 and constantly crosses over the next loop 10 and the lower loop 11. Therefore, the loop immediately before being pulled out is not in a parallel state with the next loop 10 and the lower loop 11, and a plurality of loops are not drawn out to the cylindrical cavity 4.
- This arcuate welding wire 5 acts in the direction C and is taken out while holding down the next loop 10 and the lower layer 11, so that the wire is taken out at high speed and the holding plate 3 is slightly The lower loop is not drawn out into the cylindrical cavity 4 even if it is lifted. Therefore, the welding wire 5 taken out from under the disc-shaped flat holding plate 3 is not entangled or entangled.
- the diameter of the wire extraction hole of the disc-shaped flat holding plate needs to be 180 mm or less, preferably 150 mm or less. If the diameter of the wire exit hole exceeds 18 O mm, the force of the welding wire 5 to be taken out at the corner 7 of the wire exit hole will be small, and the next loop 10 and the lower loop 11 will be held down. In some cases, the loop immediately before being taken out may come into contact with the lower layer loop 11 in parallel, and the lower layer loop 11 may be pulled out into the columnar cavity 4 and entangled or entangled.
- the diameter of the wire exit hole of the holding plate is too small. That is, assuming that the breaking strength of the welding wire is T (kgf), it is preferable that the diameter of the wire outlet hole is 0.55 T + 1 0 (mm) or more. According to the experiment, if the diameter of the wire exit hole of the holding plate is less than 0.55 T + 10 (mm) in relation to the breaking load T of the welding wire, the removed welding wire will bend. The tendency becomes remarkable. This is because if the diameter of the wire withdrawal hole of the holding plate 3 is small with respect to the breaking load of the wire, that is, the rigidity proportional to this, a bending habit is given to the welding wire 5 at the corner 7 of the wire withdrawal hole. .
- the tip position of the welding wire coming out of the torch during welding may fluctuate, and meandering of the weld bead may occur.
- the ratio WZ T is preferably in the range of 4 to 32. If WZ T is less than 4, the breaking load, that is, the rigidity of the welding wire is increased with respect to the weight of the holding plate, so that the force in the direction of arrow A shown in FIG. Is lifted up, the welding wire 5 in the upper layer of the loop body 2 jumps up, and entanglement and entanglement may occur.
- FIG. 4 is a plan view showing another example of the wire pressing member according to the present invention, in which a ring 14 through which a welding wire is passed is connected to the center of an annular flat plate 13 by three support rods 15. It was done.
- This annular flat plate 13 has a width necessary for holding the loop body, and has a function of exclusively holding the loop body, like the annular holding plate 8 in the prior art shown in FIG.
- the ring 14 is for passing a welding wire, and the inner diameter of the ring 14 naturally satisfies the dimensional conditions of the hole through which the welding wire passes in the guide portion of the present invention.
- the wire holding member shown in Fig. 4 is the one shown in Fig. 1 etc. This has the advantage that the state of the wire in the bail container can be easily seen during use, as compared with the case of FIG. Example
- No. 1 to No. 7 each have a disc-shaped flat plate with a wire extraction hole with a diameter of 180 mm or less arranged in the center of the holding plate.
- No. 1 to No. 4 are preferable conditions.
- the diameter of the hole of the holding plate satisfies 0.55 T + 10 (mm) or more in relation to the welding wire.
- the ratio W / T between the weight W and the breaking load T of the welding wire satisfies 4 to 32. Therefore, the loop just before being unrolled expands until it contacts the inner wall of the bail container, and then crosses the next loop and the lower loop to the wire extraction hole.
- the welding wire to be taken out has an arcuate shape with the corner of the wire taking-out hole as a fulcrum toward the bottom of the cylindrical container of the cylindrical cavity, and the welding wire being taken out is taken out while holding down the next loop and the lower loop. Therefore, not only the next loop but also the lower layer are not drawn out into the cylindrical cavity. Therefore, no entanglement or entanglement occurred, and the welding wire did not bend at the corner of the wire outlet hole, which was a very satisfactory result.
- the welding wire was low in rigidity relative to the weight of the holding plate, and the ratio WZ T between the weight W of the holding plate and the breaking load T of the welding wire was large.
- the previous loop cannot extend to the inner wall of the bail container, and moves along the wire exit hole while being in parallel with the lower layer loop and is taken out.
- the lower layer loop is pulled out into the cylindrical cavity once. Entanglement, tangling occurred.
- a bending habit also occurred in the welding wire due to the corner of the wire outlet hole.
- the hole diameter H of the holding plate was less than 0.55 T + 10 (mm) in relation to the breaking load T of the welding wire. Since the diameter H of the hole was small, the welding wire was bent due to the corner of the hole.
