法を選択使用している。 When using welding wire for automatic or semi-automatic welding, for example, a wire winding frame (hereinafter sometimes referred to as wire spool) as shown in Figure 1 is used.
Attach it to an automatic or semi-automatic welding machine while wrapped in 1. The welding wire 2 is given a curl (hereinafter referred to as cast) in order to prevent it from collapsing due to winding (spring pack) from the wire spool 1. On the other hand, since the welding wire 2 is wound many times around the spool core 3 of the wire spool 1, the winding radius gradually increases from the beginning of winding to the end of winding. The welding wire 2 is given a cast with a radius of curvature that approximately corresponds to the radius of its winding. That is, the cast formed on the welding wire 2 has a smaller radius of curvature r in the winding layer closer to the spool core 3 (on the bolt side), and a smaller radius of curvature R in the winding layer farther from the spool core 3 (distal side). is getting bigger. By the way, many methods of forming casts have been developed in the past, and methods that suit the actual circumstances of each manufacturing site are selected and used, taking into consideration ease of operation, processing accuracy, etc. are doing.

変化せず、溶接作業性が安定する。 EMBODIMENT OF THE INVENTION The structure and effect of this invention are demonstrated concretely below based on Example drawing. FIG. 2 is a process explanatory diagram illustrating the cast forming method of the present invention, in which the welding wire 2 fed from the welding wire supply side A is passed through a first cast roller 5 with a small diameter and a second cast roller with a large diameter. The welding wire 2 is first wound around the outer periphery of the first cast roller 5 at least once, and then sent to the second cast roller 6. After being wound once, it is fed into the wire spool 1. In the illustrated example, a presser roller 8 for fine cast adjustment is provided, and this is attached to the lower end of an elevator 7 such as a hydraulic cylinder, and the presser roller 8 is moved forward and backward toward the welding wire 2 that is running. That is, arrow A
The welding wire 2 fed from the direction is first formed into a relatively small diameter cast by the first cast roller 5, but in the example shown in FIG. conduct,
Thereafter, it is fed into a second cast roller 6 having a relatively large diameter, and the second cast roller 6 re-forms the previously formed cast into a desired cast. At this time, since the welding wire 2 has been pre-bent by the first cast roller 5, it can be re-formed into the final desired cast extremely smoothly. As described above, in the present invention, the welding wire 2 that has been pre-bent is slightly bent immediately after forming the cast, or is fed as is to the second cast roller 6, so that the welding wire 2 can be easily bent into the desired cast. can be done. On the other hand, winding around the wire spool 1 is carried out by winding the tip of the welding wire 2 around the spool core 3 in the same way as in the conventional case, but as mentioned above, since the winding radius of curvature changes from the centripetal side to the distal side, the second It is necessary to gradually increase the cast of the welding wire 2 sent out from the cast roller 6. Regarding this point, the present invention utilizes the fact that the welding wire feeding trajectory 2a toward the centripetal side changes to the feeding trajectory 2b toward the centrifugal side as the winding progresses. That is, the straightening section subjected to the bending process by the cast roller 6 is
Assuming that the outer circumferential length of is L and the overlapping lengths are 2a' and 2b', the length is shortened from L+2a' to L+2b'. That is, the bending correction section by the second cast roller 6 is (L+2a')-(L+2b')=(2a'-2b')
will decrease, and the cast will increase by the amount that decreases. Therefore, as the number of layers wrapped around the wire spool 1 increases, the cast applied to the welding wire 2 gradually becomes shorter from 2a' to 2b', and the cast with the desired radius of curvature becomes optimal. The wire is wound around the wire spool 1 while being adjusted. Furthermore, since the cast difference between the start and end of winding is also small, wire feeding performance does not change significantly between the start and end of winding, and welding workability is stabilized.

ればよい。 As described above, in the present invention, the welding wire is wound around the large cast roller, and the correction section by the large cast roller is lengthened, so that a cast with a desired radius of curvature can be formed correctly. Furthermore, since there is no uneven cast formation, uneven feeding within the tip of the welding torch and meandering of the welding line are prevented when welding wire is used, and accurate welded joints can be obtained.
Furthermore, when forming a cast with a larger radius of curvature using the cast forming method of the present invention, the second cast roller 6 may be converted to a larger diameter cast roller.
