Abstract

PURPOSE:To feed a wire accurately to a prescribed position, for example, a welding position while correcting the winding set of the wire which is curved by the winding set, etc. by feeding the wire while twisting the same circumferentially. CONSTITUTION:A welding wire 3 is inserted through the respective insertion holes 43, 44 of shafts 35, 36, and the insertion hole 45 provided to the output shaft 14a of a driving motor 14. A pressurizing roll 19 is brought into press contact with a feed roll 18 side and a motor 14 is started to revolve the roll 18, thereby feeding the wire 3 in an arrow beta direction. A starting motor 41 is started to revolve a shaft 36 in an arrow gamma direction. Since a rotating body 10 provided integrally with the shaft 36 revolves in the same direction as that of the shaft 36, the rolls 18 and 19 rotate and drive the wire 3 in the gamma direction along the circumferential direction of the wire 3 while the wire is held sandwiched under pressure, thereby acting the force in a twisting direction to the wire 3. The wire 3 is deformed torsionally at the twisting pitch determined by the feed speed at which the wire is fed and driven by the roll 18 and the rotating speed of the body 10, whereby the radius of the curvature of the largely curving wire 3 is changed to a considerably small radius and the wire is fed into a guiding tube 4.

MI that generates an arc by continuously feeding welding wire

However, since these welding wires are usually wound in a coil on a wire reel or wound in a coil on a pale acid, they inevitably have an arcuate or spiral curve. On the other hand, the guide tube itself that guides the welding wire is also made of flexible material so that it can be freely deformed in response to the working conditions at the welding site. Therefore, if a welding wire with such a curl is inserted into the wire guide tube described above, a large feeding load will be applied due to the friction generated between the welding wire surface and the inner peripheral surface of the guide tube, and the welding wire will be welded. There is a problem in that it is not possible to send the product smoothly to the other parts.

In addition, when the welding wire loaded in the pail acid is pulled out from the top of this can and led to the welding area through the wire guide tube, the welding wire should be wrapped in a loop with one circumference length. Since the wire is fed in a spiral curve, the tip of the wire constantly rotates when it exits the tip of the torch, making it impossible to determine the feeding position, making it impossible to accurately weld along the welding line. There is.

Next, when the drive motor 41 is started, the shaft 36 moves as shown by the arrow γ.
Since the rotating body 10, which is provided integrally with the shaft 36, also rotates in the direction of the arrow r together with the shaft 66, the feed roll 18 and the pressure roll 19
The welding wire 3 is rotated along the circumferential direction of the welding wire 3 in the direction of the arrow γ while being compressed, and a force in the torsion direction is applied to the welding wire 3. □ Therefore, the welding wire 3 is torsionally deformed at a twisting pitch determined by the wire feeding speed driven by the feeding roll 18, the rotational speed of the rotating body 10, and k, and the welding wire is greatly curved due to curling etc. 3 is deformed into a helical shape having a twist radius much smaller than the radius of curvature of the wire, and is fed through the wire guide tube 4.

Here, we will explain in detail how the curling tendency that the welding wire originally has is corrected by applying torsional deformation to the welding wire.

When such a welding wire 6 is fed by the feeding device 1 according to the present invention and subjected to torsional deformation, it is deformed into a spiral shape as shown in FIG. 4(b).

Here, the torsion radius of the welding wire 3 that has been twisted and deformed in a spiral shape is a, and the so-called torsion pitch in which the virtual side line 103 makes one revolution around the feeding axis 3C of the welding wire 3 is P. It has been found from various study results that there is a relationship similar to the following equation between the twist pitch P and the twist radius a.

(R is the radius of curvature of the wire, and d is the diameter of the wire.) Using this relational expression, the relationship between the twist pitch P and the twist radius a is illustrated as shown in FIG. 5'.

これらのグラフからねじりピッチPの値を小さくすれは

From these graphs, the smaller the value of the twist pitch P, the smaller the value of the twist radius a.

In other words, it is understood that by reducing the value of the twist pitch P, the amount of deviation of the welding wire 3 with respect to the feed shaft 3C becomes smaller, and the welding wire 6 is corrected to a state closer to a straight line. It is also understood from these graphs that the larger the curl and the smaller the radius of curvature R10-, the smaller the value of the twist pitch P needs to be.

By the way, as already mentioned, the value of the twisting pitch P is determined by the feeding speed of the welding wire and the twisting rotational speed, and reducing the value of the twisting pitch P means that the above twisting rotational speed is changed by the wire feeding speed. It means to be larger than . Therefore, the faster the rotational speed of the rotating body 10 is within a certain range, the more the welding wire 6
It can be easily seen that the straightening of the curvature is corrected to a straighter state. By the way, the radius of curvature R is 3001J+.

When the value of the twist pitch P is 508, the twist radius a becomes 0.2 mm, and at this degree of twist radius, the welding wire 6 can be regarded as substantially straight.

In addition, in the practical test results, the value of the torsion radius a is 0.1 to 0.
.. Even if a slight spiral curvature remains between 2 and 3, there is no problem with the feeding accuracy for the welding position, and if this degree of curvature remains, the contact power feeding effect within the tip of the welding torch will be reduced. It was also confirmed that there is a new effect that actually improves.

Therefore, if the wire feeding device based on the present invention is used to feed a wire that is curved due to curling, etc., the wire will be straightened to a state that approximates a straight line. Since the feeding load is significantly reduced and the wire can be fed smoothly into the guide tube, and the wire can be fed accurately to the predetermined welding position, automatic arc welding can be performed along the welding line. can be carried out smoothly and accurately. In this embodiment, the drive motor 1 that drives the feed roll 18
4 and a drive motor 41 for rotationally driving the rotary body 10 are provided independently, however, for example, both the feed roll 18 and the rotary body 10 may be rotationally driven by the drive motor 14 alone.

In this way, since only one driving source is required, the device itself can be made compact and power consumption can be reduced, making it possible to obtain an extremely economical wire feeding device. The other effects are exactly the same as those of the above-mentioned embodiment, and therefore their explanation will be omitted. Further, FIG. 7 shows an example in which the wire feeding device 70 shown in FIG. 6 is applied to a semi-automatic arc welding device. In this case, the wire feeding device 70 is
The welding wire 6 is provided on the fA71 side, and the welding wire 6 straightened by the wire feeding device 70 is inserted into the guide tube 72 and fed to the welding torch portion 73.
