[ The arc-shaped wire feeding device according to one example is characterized in that the curvature of the outlet side fusing material receiving surface is larger than the curvature of the inlet side fusing material receiving surface of the arc-shaped wire feeding device. The curvature of the inlet side fusing material receiving surface may be the curvature of the bottom surface of the inlet side guide hole 113 or the curvature of the fusing material receiving surface of the first roller unit 31 that is seated in the front side roller seating hole 10a, The curvature of the surface of the second roller unit 33 may be the curvature of the bottom surface of the rear side guide hole 113 or the curvature of the filler bearing surface of the second roller unit 33 that is seated in the rear side roller seating hole 10a. Hereinafter, each configuration will be described in detail with reference to the drawings.

First, the guide unit 10 includes a plurality of guide holes 113 and roller seating holes 10a. 3, the guide unit 10 is shown to include a guide body 11 and a plurality of guiders 13, in which a roller seat 10a is formed in the guide body 11, And a plurality of guiders 13 that are seated on the guide 11 are each provided with a guide hole 113. 3, the guide body 11 and the plurality of guiders 13 are integrally formed so that the plurality of guide holes 113 and the roller seating holes 10a may be formed in a unitary structure have. Alternatively, although not shown, a plurality of guiders 13 each having a guide hole 113 are mounted on a frame (not shown) of the guide body 11 of Fig. 3, and a roller seat hole 10a may be formed.

2, 4A and / or 4B, the plurality of guide holes 113 are formed in an arc shape at least on the lower surface to guide the arc-shaped wire member 1. [ At this time, the structure formed in the arc shape is a downward arched structure, that is, a concave shape in a direction in which a load is applied. The arc-shaped wire roughening material 1 refers to a linear roughening material having an arc-shaped cross section. For example, the cross-sectional shape of the guide hole 113 may be various shapes such as an arcuate shape, a rugby shape, an arc shape as a part of a ring, and the like. The lower surface of the guide hole 113 may have an arcuate shape so as to support and guide the arc-shaped wire sealant 1. [

For example, referring to FIG. 4B, the curvature of the lower surface of the guide hole 113a of the guide unit 10 may be the curvature of the inlet-side abrading member receiving surface of the arc-shaped wire feeder, The curvature of the lower surface of the side guide hole 113c may be the curvature of the exit side bearing abutment surface of the arc-shaped wire feeder. That is, the lower curvature of the lower guide hole 113c is larger than the lower curvature of the entrance guide hole 113a.

In addition, in one example, the size of the entrance guide hole 113a of the guide unit 10 is larger than the size of the guide hole 113c on the rear side of the guide unit 10. [ For example, referring to Figs. 4A and / or 4B, the size of the first guide hole 113a on the entrance side is larger than the size of the third guide hole 113c on the exit side.

Next, the roller seating holes 10a of the guide unit 10 are formed so as to open upward and downward from the front side and the rear side of the guide unit 10, respectively. The roller units 31 and 33 are seated on the upper and lower sides in the seating holes 10a opened upward and downward. At this time, an arc-shaped wire padding material 1 guided through the guide hole 113 on the entrance side of the guide unit 10 is interposed between the roller units 31 and 33 which are seated on the upper and lower sides in the seating hole 10a, . For example, the guiding body 11 and the plurality of guiders 13 may be formed on or integrally formed with the guiding body 11, as shown in FIG. 3, Or may be formed in an open space shape between a plurality of guiders 13 in a frame (not shown) on which the frame 13 is mounted. The roller units 31 and 33, which are seated on the upper and lower sides of the roller receiving holes 10a of the guide unit 10, feed and feed the arc-shaped wire bonding material 1 therebetween.

Referring to FIG. 3, in one example, the guide unit 10 may include a plurality of guiders 13 and a guide body 11. At this time, guide holes 113 are provided on the lower side of the guider 13, respectively. The guider 13 is seated on a guider seat portion 11a formed on the guide body 11. [ That is, the guider 13 is detachably seated on the guider seat portion 11a, so that the guider 13 having the guide hole 113 having an appropriate size and / or curvature can be mounted on the guider seat portion 11a, (11a). The guide body 11 is provided with a roller seating hole 10a on the front side and a rear side respectively. A guider seat portion 11a is formed on one side or both sides of the front and rear sides of the respective roller seating holes 10a of the guide body 11. [ At this time, a plurality of guiders 13 are seated on each of the plurality of guider seating portions 11a.

Next, another example will be described with reference to FIG. 3, a plurality of guider seating portions 11a are formed in front of the front roller-seating holes 10a, between the front-side and rear-side roller-seating holes 10a, and between the rear-side roller-seating holes 10a 10a. 3, the plurality of guiders 13 are formed by first, second and third guiders 13a, 13b, and 13c so as to be seated from front to back on the three guider seating portions 11a, respectively. do. That is, the first guider 13a is disposed in front of the front roller-seating hole 10a, the second guider 13b is disposed between the front and rear roller-seating holes 10a, and the third guider 13c, Is mounted on the rear side of the rear roller receiving hole 10a, that is, on the rear side of the guider unit 10.

Referring to FIG. 4B, in one example, the lower curvature of the first guide hole 113a formed in the first guider 13a is smaller than that of the third guide hole 113c formed in the third guider 13c. This is big. In this case, reference symbol R1 denotes the radius of curvature of the filler material 1 passing through the first guide hole 113a, and R3 denotes the radius of curvature of the filler material 1 passing through the third guide hole 113c. In this case, in one example, the cross section of the first, second, and third guide holes 113a, 113b, and 113c may be any one of an arctic shape, a rugby shape, and an arc shape as a part of a ring. In Figs. 2, 4A and / or 4B, the guide hole section of the rugby ball type is shown, but it is also possible to use an arcuate shape, an arcuate shape which is a part of the ring, and the like.

4A and 4B, in one example, the first guide hole 113a formed in the first guider 13a has a third guide hole 113c formed in the third guide 13c, 113c formed in the second and third guiders 13b, 13c, as compared with the size of the first guide holes 113b, 113c. That is, the size of the first guide hole 113a on the entrance side is larger than the size of the rear side third guide hole 113c or the second and third guide holes 113b and 113c.

For example, in Fig. 3, the first, second and third guiders 13a, 13b, and 13c may be interchangeably coupled to the guider seat portion 11a. Accordingly, the guide hole 113 can be replaced by a guider 13 having a different size. Also, the second or third guiders 13b, 13c among the first, second and third guiders 13a, 13b, 13c may be omitted.

Alternatively, unlike in FIG. 3, there are two guiding seats 10 on the front side of the front side roller seating hole 10a, that is, between the entrance side and the front and rear roller seating holes 10a or behind the rear side roller seating holes 10a, And the inlet side guider 13a and the rear side guider 13c may be seated on the guider seating portion 11a, respectively.

Next, the roller unit 30 of the arc-shaped wire feeding device will be described in detail. Referring to FIG. 1, the roller unit 30 includes a first roller unit 31 and a second roller unit 33. The first roller unit 31 is seated on the upper and lower sides in the front roller seat 10a of the guide unit 10. The first roller unit 31 serves to adjust the center of the arc-shaped wire fusing material 1 flowing through the entrance-side guide hole 113a. For example, as shown in Fig. 4A, the center of the arc-shaped wire padding material 1 passing through the entrance guide hole 113a or the first guide hole 113a of Fig. 3 does not coincide with the center of the guide hole 113 The arc-shaped wire fusing material 1 passes between the upper roller 31b and the lower roller 31a of the first roller unit 31 and the center is adjusted. 4A shows a state in which the arc-shaped wire bonding material 1 having passed through the first roller unit 31 and having its center corrected passes through the guide hole 113c of the rear guider 13c at the rear end of the second roller unit 33 .

2, a horizontal end 231b on both sides of the convex portion 131b of the upper roller 31b on the section in the first roller unit 31 and a horizontal end 231b on both sides of the concave portion 131a of the lower roller 31a The distance between the end portions 231a is larger than the distance between the apex of the convex portion 131b and the bottom point of the concave portion 131a. That is to say, both horizontal end portions 231b of the convex portion 131b and both horizontal end portions 231a of the concave portion 131a are spaced from the vertex of the convex portion 131b and the bottom point of the concave portion 131a. Thus, arc-shaped wire fusing material 1 with the center turned is inserted between the upper roller 31b and the lower roller 31a of the first roller unit 31 and the rotation of the upper roller 31b and the lower roller 31a The left or right end portion of the arc-shaped wire roughening material 1 is brought into contact with the horizontal end portion 231b on both sides of the convex portion 131b of the upper roller 31b. At this time, as the upper roller 31b rotates, the height of the horizontal end portion 231b on both sides of the convex portion 131b of the upper roller 31b is lowered and the end of the arc-shaped wire roughening material 1 is pressed, The center of the arc-shaped wire filler material 1 can be adjusted to the center of the concave portion 131a.

Further, the second roller unit 33 is seated on the upper and lower sides in the roller-receiving hole 10a on the rear side of the guide unit 10. [ The second roller unit 33 sends the centered arc-shaped wire melt-bonding material 1 through the first roller unit 31.

1, in one example, the first and second roller units 31 and 33 may be composed of upper rollers 31b and 33b and lower rollers 31a and 33a, respectively. For example, referring to FIG. 1, the first and second roller units 31 and 33 are coupled to the body frame 20. Referring to FIG. 2, the upper rollers 31b and 33b are formed with convex portions 131b protruding outwardly and the lower rollers 31a and 33a are formed with concave portions 131a concaved toward the center. At this time, arc-shaped wire bonding material 1 is interposed between the convex portion 131b of the upper rollers 31b and 33b and the concave portion 131a of the lower rollers 31a and 33a. Although the upper roller 31b and the lower roller 31a of the first roller unit 31 are shown in Fig. 2, the second roller unit 33 may have a similar shape.

The second roller unit 33 or the first and second roller units 31 and 33 can be interchangeably installed so that the arc-shaped wire rods 1 can be calibrated so as to maintain an appropriate curvature if necessary. For example, the upper rollers 31b and 33b and the lower rollers 31a and 33a can be replaced, so that the curvature of the arc-shaped wire joining material 1 interposed therebetween can be calibrated in a feeding process.

At this time, the second roller unit 33 can calibrate and transmit the deformed curvature in the process of feeding the arc-shaped wire consumable 1. At this time, although not shown, the gap between the upper roller 33b and the lower roller 33a of the second roller unit 33 can calibrate the arc-shaped wire filler material 1 according to the set curvature. For example, at this time, the second roller unit 33 may perform heat pressurization in order to effectively calibrate the curvature of the arc-shaped wire roughening material 1.

For example, although not directly shown, the curvature of the filler bearing surface of the second roller unit 33 on the rear side is larger than the curvature of the filler bearing surface of the first roller unit 31 on the front side. For example, the consumable material receiving surface may be a curved surface of the concave portion 131a formed in the lower roller of each roller unit.

Referring to Fig. 4B, in the front end drawing, the front end of the second roller unit 33, specifically the guide hole 113a of the inlet side guider 13a formed at the front end of the first roller unit 31, The case where the curvature 1 / R ₁ of the arc-shaped wire filler material 1 is deformed or not set is shown and in the following figure, the curvature 1 / R ₃ is corrected through the second roller unit 33 Shaped wire scraper 1 passes through the guide hole 113c of the rear guider 13c formed at the rear end of the second roller unit 33. [

At this time, in another example, the curvature of the convex portion and the concave portion of the second roller unit 33 may be formed to be larger than the curvature of the convex portion 131b and the concave portion 131a of the first roller unit 31 , Whereby the curvature of the arc-shaped wire roughening material (1) is largely corrected and sent out by the second roller unit (33). In this case, the concave curvature of the first roller unit 31 may be the curvature of the inlet-side fryer-receiving surface, and the concave curvature of the second roller unit 33 may be the curvature of the outlet-

4B, the curvature of the lower surface of the guide hole 113, for example, the second or third guide hole 113c on the guide unit 10 on the rear side of the second roller unit 33, 113, that is, the curvature of the lower surface of the first guide hole 113a. At this time, the curvature of the bottom surface of the first guide hole 113a becomes the curvature of the inlet-side frying-material receiving surface, and the curvature of the bottom surface of the third guide hole 113c becomes the curvature of the outlet-

For example, the curvature of the bottom surface of the first guide hole 113a and the curvature of the concave portion of the first roller unit 31 may be selected as the curvature of the inlet-side fryer support surface, The bottom curvature of the third guide hole 113c and the curvature of the concave portion of the second roller unit 33 may be optional or both.

1, in another example, the arc-shaped wire feeding apparatus may further include a gap adjusting unit 50. [ The gap adjusting unit 50 is configured to adjust the gap between the upper rollers 31b and 33b and the lower rollers 31a and 33a in the first and second roller units 31 and 33 according to the thickness of the arc- Can be adjusted. For example, the upper frame 21 to which the upper rollers 31b and 33b of the first and second roller units 31 and 33 are coupled is connected to the lower rollers 31a and 31b of the first and second roller units 31 and 33, And 33a may be coupled to the lower frame 22 to which the lower frame 22 is coupled.

1, in one example, the arc-shaped wire feeding apparatus further includes a gear unit 40. [ The gear unit 40 serves to drive the lower rollers 31a and 33a of the first and second roller units 31 and 33 or to drive both the upper and lower rollers. In Fig. 1, the gear unit 40 is shown driving the lower rollers 31b, 33b of the first and second roller units 31, 33.

For example, in one example, arc-shaped wire filler 1 fed in an arc-shaped wire feeder may be a filler used, for example, for TIG welding.
