Description

Bonded welding wire coil and binding method {BOUND WELDING WIRE COIL AND THE METHOD FOR BINDING THE COIL}

The present invention relates to a welding wire coil and a binding method, wherein the welding wire is bound with a binding wire for coil winding to maintain a coil shape.

Flux-filled welding wires or solid welding wires having a diameter of 0.6 to 2.4 mm for use in arc welding, for example, are manufactured in the form of coils, which are wound by laminating onto coils. In other words, the welding wire is coiled in a cylindrical shape (doughnut shape), and its weight is made from 1 to 20 kg, coil inner diameter of 50 to 180 mm, and coil width of about 40 to 100 mm as one unit.

This welding wire coil is wound using a winding frame such as a reel or spool (for example, Japanese Patent Application Laid-Open No. 58-10346 or Japanese Patent Application Laid-Open No. 62-19646), and a coil winding after winding. In this case, only the wire coil, the binding wire, the wide steel band, and the plastic band may be bound together. For example, Japanese Unexamined Patent Application Publication No. 5-84573 does not use a winding frame such as a reel, but restrains it with a retainer that can detach a coil body wound on a coil. As the restraint holding region, a needle bent in a U shape or a clip-shaped metal wire jig having a spring action is exemplified. Japanese Patent Laid-Open No. 6-278719 discloses a method of stacking a coil body in a bag shape with an alumina composite film and sealing after degassing.

In welding, it is necessary to rewind the wire from the coil so that the welding wire is not entangled. If the shape of the welded wire coil collapses, entanglement is likely to occur. Therefore, the coil needs to be protected and transported so as not to deform. When using a coil with a winding frame, the winding frame is coupled to the shaft of the wire feeding device of the welding machine, and the welding wire is taken out from the winding frame and fed to the welding head. In the case of a coil without a winding frame, it is mounted on a winding frame such as a spool, that is, a feeding adapter, and the feeding adapter is coupled to a shaft of a wire feeding device (for example, Japanese Patent Laid-Open No. 5-11770, Japanese Patent Laid-Open No. 5). 200553).

The user removes the above-described welding wire coil and attaches it to the supply adapter, and as shown in Fig. 16A, the supply adapter 12 is mounted on the feeder 13 of the welding machine and the feed adapter 12 is removed from the supply adapter 12. The welding wire is drawn out to start welding through the feed roller 15, the conduit liner 16 and the welding torch 17 of the welder, but as the welding proceeds, the coil is consumed and the rest of the feed adapter 12 When the wire is near the lowermost layer, as shown in Fig. 16B, the remaining wire of the supply adapter 12 is splashed and scattered. As a result, the welding wire may be entangled with the supply adapter support shaft, and when the entanglement is entangled, wire feeding may be interrupted.

The present invention maintains the coil winding layered shape even in a welding wire coil that does not use a reel winding frame, and preferably eliminates the trouble of removing the binding wire when used for welding, and at the same time avoids the tip projection of the binding wire. It is a primary object. The second object is to prevent the collapse of the coil shape during transportation, and the third object is to facilitate mounting to the welding machine. A fourth object is to prevent the retraction of the wire of the rewind boil that the remaining wire of the coil is less.

(1) The welded wire coil of the present invention for achieving the first object comprises: a welded wire coil (1) having a cross-section substantially flat plate-shaped, and an outer circumferential surface between the cross-sections thereof being a substantially cylindrical thick cylindrical surface;

A plurality of bundling wires bent at right angles along the inner circumferential surface and both end faces of the coils and bent at right angles along the outer circumferential surface of the coil to surround the coil in a rectangular loop shape (3a) ˜3d); And

Connecting wires 2 and 1e along the circumferential direction on the outer circumferential surface thereof and thereby fastening the embossed portions of the binding wire to the outer circumferential surface so as to push the embossed portion of the binding wire substantially parallel to the outer circumferential surface of the coil; Including,

The tips 3as to 3ds and 3ae to 3de of each of the binding wires are folded back to circumscribe the connecting wires. In addition, in order to facilitate understanding, the reference numerals of the corresponding elements of the embodiments shown in the drawings and described later are shown in parentheses.

According to this, in the connection portions of the binding wires 3a to 3d to the connection wires 2 and 1e, each of the binding wire terminals are folded back (inverted by 180 degrees), so that the tip projection is small. The bundled welding wire coil is stored in a packing box 21 (Figs. 9A to 12A) which is a holder for shipping, for example, and shipped. When the user uses the welding wire coil 1, the user attaches the coil 1 to the supply adapter 5 (Fig. 15), which is a holder for welding use, and then connects the connecting wires 2 and 1e connected in the hoop shape. At the same time as the fastening is released, the start end 2s or the end 2e is pulled out (pulled in the coil tangential direction). The connecting wires 2 and 1e then exit the connecting portions of the binding wires 3a to 3d and are pulled out of the coiled welding wire 1. As a result of the disconnection of the connecting wires 2 and 1e, the connecting portions of the binding wires 3a to 3d are released at once, and it is not necessary to release the connecting portions of the binding wires 3a to 3d, respectively. When the binding wires 3a to 3d are removed, the binding release operation of the coil wound welding wire 1 is completed (to be described later).

(2) The tip ends of the embossed portions of the binding wires 3a to 3d are chained together (i.e., mean they are engaged and engaged) (Figs. 7B and 8B). The tips 3ds, 3de; 3as, 3de of the embossed portions of the binding wires 3a to 3d are engaged with each other, so that the ends of the embossed portions fall in the direction in which the connecting wires 2 and 1e are relatively long (coil circumferential direction). There is no work.

(3) The welding wire coil 1 has a hook type (1sr, 1sa) in which the end (1s) at the same time as the innermost layer and the winding end (1s) of the cylindrical end is bent in the radial direction of the coil loop and bent in the direction parallel to the coil center line. 1, 5 (to be described later). When the coil 1 is mounted on the wire feed adapter 5, the winding start end 1s is engaged with the wire feed adapter 5, so that the winding start end 1s rotates together with the wire feed adapter. As a result, the wire does not slip against the wire feed adapter.

(4) The connecting wire is the final winding loop 1e of the welding wire coil, and the binding wires 3a to 3d surround the coil winding welding wire except for the final winding loop.

(5) The end of the final winding loop 1e is engaged with the binding wire 3a.

(6) The tips of the embossed portions of the binding wire 3a are rotated and folded about a line perpendicular to the outer circumferential surface of the welded wire coil so that the ends thereof cross each other and further round the final winding loop 1e. The final winding loop 1e is bent in an S shape and engaged with the binding wire 3a.

(7) A plurality of binding wires (3a to 3d) pass through the plurality of binding wires (3a to 3d) through the center space of the welded wire coil (1), in which both end surfaces are substantially flat ring shapes, and the outer circumferential surface between the both ends is a thick cylindrical shape of a substantially cylindrical surface. Bend at right angles to follow the inner circumferential surface and both end faces, except for the final winding loop (1e), and bend the bent corners at right angles to follow the outer circumferential surface to enclose the coil in a rectangular loop shape, and the embossed portion almost parallel to the outer circumferential surface of the coil Follow the final winding loop 1e along the circumferential direction on the outer circumferential surface so as to be pushed to the outer circumferential surface, thereby fastening the embossed portion of the binding wires 3a to 3d with respect to the outer circumferential surface, and distal end of the embossed portion of the binding wires 3a to 3d. Fold the welding wire of the final winding loop 1e so as to be circumferentially, and at least, at the distal end of the final winding loop 1e, the tip of each of the binding wires 3a At the same time, the front end of the two ends of the binding wire 3a is circumferentially connected to the end of the binding wire 3a, and the ends perpendicular to the outer peripheral surface of the welding coil 1 are connected. Fold back to rotate around the center.

Bonding method of welding wire coil.

Other objects and features of the present invention will become apparent from the following description of the preferred embodiments (plural) with reference to the drawings.

(Explanation of a preferred embodiment (plural))

1 shows a coil 1 of the first embodiment. The coil 1 is cylindrical and its coil cross section is rectangular. The coil 1 has a weight of about 10 kg to 20 kg, and the coil outer diameter (cylinder outer diameter) and coil inner diameter (cylinder inner diameter) are determined depending on the use conditions. The coil 1 has a connecting wire 2 that is separate from the coil winding welding wire along the width center of the outer peripheral surface 1g. Moreover, four places and the binding wires 3a-3d bind the cylindrical coil part of the coil 1 at intervals of approximately 90 degrees. After binding, the winding start start end (1s), which is at the end of the innermost cylindrical end and is the loop end, is first bent in the radial direction of the loop to be the radial side (1sr), and then approximately half of the tip side is coil shaft. Is bent in the coil inward direction in parallel to the axial parallel edge 1sa, and the winding start stage 1s is hooked.

In FIG. 2, the knot of the front-end | tip of the connection wire 2 shown in FIG. 1 is expanded and shown. The start end 2s and the end 2e of the connecting wire 2 are crushed in the mutually attracting state, such as by tightening the outer circumferential surface 1g (Fig. 1), so that the start end 2s and the end 2e face in the opposite directions, respectively. I'm bending to. As a result, the connecting wire 2 is fixed to the width center of the outer circumferential surface 1g. 1.4 mm ø solid wire (mild steel wire) is used for the connecting wire (2). Although the material is difficult to bend (plastic deformation), the tensile strength is large and the elongation is small, and it is suitable for the connecting wire 2. Table 1 shows the physical properties of the connecting wire 2 and the binding wires 3a to 3d.

Wire [1.4 ° TSN / ㎡ EL (%) Hardness (Hv) Binding wire 325-330 30.3-32.2 100-104 Connection wire 832-862 1.6-2.1 278-282 TS: tensile strength. In the tensile test, the numerical value obtained by dividing the tensile load under which the test piece breaks by the first cross-sectional area of the test piece. EL: elongation percentage. If the gage length before tension of the tensile test piece is broken by L. Tension, L = EL = [(L-Lo) / Lo] × 100.

3A and 3B show enlarged knots (connections) of the distal end of the binding wire 3c. The binding wire 3c is circumscribed along the coil end face (rectangular) of the coil 1, and the start end 3cs and the end 3ce are connected to the connection wire 2. That is, there is a connecting wire 2 on the start end 3cs and the end 3ce of the binding wire 3c which is circumferentially along the coil section (rectangular), and on the start end 3cs and the end 3ce of the binding wire 3c. The connecting wire 2 is wound about half by bending in the opposite direction in the state of applying the tensile force. The start end 3cs and the end 3ce are bent in the state in which the connecting wire 2 was wound, without interchanging.

4 shows the binding process of the binding wire described above. Furthermore, although the knot of the binding wire 3c has been described above, the process of the knot of the binding wire 3a is shown in FIG. The binding wires 3a to 3d are coupled to the connecting wire 2 in the same knot method.

A 1.4 mm diameter line (wire annealed a piano wire) was used for the bonding wires 3a to 3d. The material is easy to bend (plastically deform), but its tensile strength is small and increases. However, in the case of binding the coil 1 having a rectangular coil end face, the angle of the end face of the coil is not deformed by using a material which is easy to bend (plastic deformation), so that the material is the binding wire 3a to 3d. (See Table 1). Using the material, as shown in Figs. 3A and 3B, when the beginning 3cs and the end 3ce of the binding wire 3c are knotted and knotted, the knot withstands a tensile force of at least 10 kgf. The terminals of the other binding wires 3a, 3b, and 3d are similarly connected to the connection wire 2.

In Fig. 5, the coil 1 of the second embodiment is shown. The welding wire winding shape of the coil 1 is the same as that shown in Fig. 1, but the final winding loop 1e of the welding wire is used for about one week at the end of the coil as the connection wire. The cylindrical coil portion of the coil 1 is bound by four places and binding wires 3a to 3d at approximately 90 degree intervals. The material used as the binding wire is the same as that used for the coil 1 shown in FIG. After binding, the winding start start end 1s at the innermost cylindrical end and loop end is first bent in the radial direction of the loop to the radial side 1sr, and then approximately half of the tip side is coiled shaft. Is bent in the coil inward direction in parallel to the axial parallel edge 1sa, and the winding start end 1s is hooked.

FIG. 6 is an enlarged view of the knot of the distal end portion of the connecting wire (final winding loop of the welding wire) 1e shown in FIG. 5. By holding both ends of the connecting wire 1e and the loop before 1 loop, the both ends of the binding wire 3a are folded back, and the ends of the connecting wire 1e are held as if the binding wire 3a is held. By folding, the end of the connecting wire 1e is locked to the binding wire 3a. Both ends of the binding wire 3a are folded in a U-shape and are connected to each other at the same time.

7A and 7B show knots for the connecting wire 1e of the binding wire 3d. The binding wire 3d is coupled to the connecting wire 1e by folding both ends thereof as if the connecting wire 1e is held. Both ends of the binding wire 3d are folded in a U-shape and are connected to each other at the same time. Other binding wires 3b and 3c are also joined to the connecting wire 1e by the same knot method as in 3d.

8 shows a modification of the knotting method of the binding wire 3a for fixing the distal end of the final winding loop 1e when the final winding loop 1e of the welding wire is used as the connecting wire. In this variant, the tip ends 3as and 3ae of each of the binding wires 3d are rotated by 180 ° about a line perpendicular to the outer circumferential surface of the coil 1 so that the ends intertwine and circumscribe the connecting wire 1e. It was bent back, thereby forming an S-shaped bending process in the final winding loop. Since the final winding loop 1e is caught by the binding wire 3a by this S-shaped bending, it is necessary to form an L-shaped bend (Fig. 6) at the end of the final winding loop 1e for locking. There is no. Further, in the knot-gluing operation of the binding wire 3a, when it is difficult to bend the final winding loop in the S-shape, bending processing is formed in the S-shape at the end of the final winding loop until the binding wire 3a is knotted.

A cross sectional view is shown in FIG. 9B for a longitudinal section of the packaging box of the first aspect in which the coil 1 described above is accommodated in FIG. 9A. The coil 1 which does not have a pulsation, such as a spool, is accommodated in the corrugated cardboard box 21 in a vertical form (coil axis is received in the Y direction). If necessary, a plurality of packing boxes 2 containing the coils 1 are stacked and transported in containers. The upper surface of the outer box 21b constituting the packing box 21 is a lid that can be opened and closed by hinged one side thereof in contact with the vertical horizontal surface 21s3 or 21s4. The coil 1 is bound by the binding lines 3a to 3d to form a cylindrical shape (doughnut; the cross section is rectangular), and its outer circumference is in contact with the bottom of the outer box, so that the coil 1 is easily moved (rotated). )easy to do. When the coil 1 is moved (rotated), it hits the vertical sides 21s1 and 21s2 of the outer box 21b and breaks it, or the coil 1 is placed on the vertical sides 21s1 and 21s2, It is likely to deform and collide.

Thus, the movement preventing blocks 21b1 and 21b2 made of corrugated cardboard are disposed on the bottom surface 21bm of the outer box 21b. The movement preventing blocks 21b1 and 21b2 have a triangular zx cross section, and the length in the longitudinal direction (y direction) matches the inner depth of the outer box 21b, that is, the inner depth of the bottom surface 21bm. These movement preventing blocks 21b1 and 21b2 are attached to the bottom plate 1p made of corrugated cardboard. The size of the bottom plate 1p is matched to the inner dimension of the bottom surface 21bm of the outer box 21b, so that the blocks 21b1 and 21b2 and the bottom plate 1p are fitted to the bottom surface of the outer box 21b to move. none.

The direction of the triangular side b1a formed by the block 21b1 is directed toward the center CR of the coil 1, and the direction of the triangular side b1b formed by the block 21b1 is the coil ( It is prepared to coincide with the circumferential tangent (a) of 1). The direction of the triangular side b2a of the block 21b2 is directed toward the center CR of the coil 1, and the direction of the triangular side b2b of the block 21b2 is the coil 1. It is made to coincide with the circumferential tangential direction of (b).

Since the position where the block 21b1, 21b2 and the outer peripheral surface of the coil 1 contact is selected in the height (Z direction) which the lowest position of the coil 1 will contact the bottom plate 21p, the coil 1 will be 3 Supported at this point, the weight load on the packing box 21 is distributed, and at the same time, there is no rattling. The position where the block 21b1, 21b2 and the outer peripheral surface of the coil 1 contact may be made into the height (Z direction) from which the lowest position of the coil 1 and the bottom plate 21p may fall. Since the coil 1 is hollow-supported at two points by the blocks 21b1 and 21b2, the stability is high. Even if the coil 1 pushes the blocks 21b1 and 21b2 to move (rotate) in the x-direction, the compressive strength of the blocks 21b1 and 21b2 is large, so that there is no deformation and the transfer prevention is large. Since the movement preventing blocks 21b1 and 21b2 are made of corrugated cardboard, they are easily manufactured at low cost and light weight. Since the packing boxes 21 including the movement preventing blocks 21b1 and 21b2 are all made of corrugated cardboard, there is no particular problem as industrial waste in the disposal.

10A and 10B show longitudinal sections and cross sections of the packaging box of the second aspect. The outer box 21b is the same as the first embodiment described above, but the movement preventing blocks 21b1 and 21b2 are different. In this second aspect, the movement preventing blocks 21b1 and 21b2 and the bottom plate 21p are made by bending one long thin corrugated cardboard, and the depth thereof (y direction length) of the bottom surface 21bm of the outer box 21b. I match it with the measure length length measure. In other words, both ends of the long and thin corrugated cardboard were bent in a spiral shape so that the cross section was triangular, so that the movement preventing blocks 21b1 and 21b2 were formed. The direction of the triangular side b1a which the block 21b1 makes, and the direction of the side b1c which the end part of the corrugated cardboard forms are directed toward the center CR of the coil 1, and the block 21b1 The direction of the triangular sides b1b to be formed coincides with the outer circumferential tangent a of the coil 1.

The direction of the triangular side b2a which the block 21b2 makes, and the direction of the side 62C which the terminal end part of cardboard forms is made so that the coil 1 may face the center CR, and the block 21b2 makes 3 The direction of the square side b2c is made to coincide with the outer circumferential tangential direction b of the coil 1.

The size of the plane of the movement preventing block 21b1, 21b2 and the connection part of both blocks is matched with the inner dimension of the bottom face 21bm of the outer box 21b. Therefore, the connection portions of the blocks 21b1 and 21b2 and both blocks are fitted to the bottom surface of the outer box 21b, and do not move.

Since the position where the block 21b1, 21b2 and the outer peripheral surface of the coil 1 contact is selected by the height (Z direction) which the lowest position of the coil 1 will contact the bottom plate 21p, the coil 1 will be 3 Supported at this point, the weight load on the packing box 21 is distributed, and at the same time, there is no rattling. The position where the block 21b1, 21b2 and the outer peripheral surface of the coil 1 contact may be made into the height (Z direction) from which the lowest position of the coil 1 and the bottom plate 21p may fall. Since the coil 1 is hollow-supported at two points by the blocks 21b1 and 21b2, the stability is high. The triangular sides formed by the movement preventing blocks 21b1 and 21b2 have a double structure except the sides b1b and b2b, and do not deform because they have a high compressive strength. The direction of the triangular sides b1b and b2b formed by the movement preventing blocks 21b1 and 21b2 is the same direction as the circumferential tangential direction of the coil 1, and when the coil 1 tries to move (rotate) in the x direction. The movement prevention strength of is high.

11A and 11B show longitudinal sections and cross sections of the packaging box of the third aspect. The outer box 21b is the same as the first and second aspects described above, but the movement preventing blocks 21b1 and 21b2 are different. In this third aspect, the movement preventing blocks 21b1 and 21b2 and the bottom plate 21p are made by bending one long thin corrugated board, and the depth thereof (y-direction length) is the width of the outer box 21b, that is, vertically. The inner dimensions of the side surfaces 21s1 and 21s2 are matched. In other words, the ends of the long and thin corrugated cardboard were bent in a spiral shape so that the xz section became a double triangle, thereby forming the movement preventing blocks 21b1 and 21b2. The block 21b1 is composed of a large triangular t1 on the outside and a small triangular t2 on the inner side, and the large triangular t1 on the outside is on the vertical side 21s1 of the outer box 21b on one side. The inner side extends in the z direction, the one side extends in the x direction in the inner side of the bottom surface 21bm, and the other side b1b forms a right-angled triangular shape that extends in contact with the outer circumferential tangent of the coil 1. The direction of the side b1a of the inside small triangular shape t2 is created so that it may face the center CR of the coil 1, and the side b1d is inscribed in the side b1b.

Moreover, the block 21b2 consists of an outer large triangle t3 and the inner small triangle t4, and the outer large triangle t3 has one side of the vertical side surface 21s2 of the outer box 21b. Inwardly extends in the z direction, one side extends in the x direction inwardly to the bottom surface 21bm, and the other side b2b forms a right-angled triangular shape that extends in contact with the outer circumferential tangent of the coil 1. The direction of the side b2a of the inside small triangular t4 is created so that it may face the center CR of the coil 1, and the side b2a is inscribed in the side b2b.

The size of the plane of the movement preventing blocks 21b1 and 21b2 is matched to the inner dimension of the bottom surface 21bm of the outer box 21b. Therefore, the connecting portions of the blocks 21b1 and 21b2 and both blocks are fitted to the bottom surface of the outer box 21b and do not move.

Since the position where the block 21b1, 21b2 and the outer peripheral surface of the coil 1 contact is selected in the height (Z direction) which the lowest position of the coil 1 will contact the bottom plate 21p, the coil 1 will be 3 Supported at this point, the weight load on the packing box 21 is distributed, and at the same time, there is no rattling. The position where the block 21b1, 21b2 and the outer peripheral surface of the coil 1 contact may be made into the height (Z direction) from which the lowest position of the coil 1 and the bottom plate 21p may fall. Since the coil 1 is hollow-supported at two points by the blocks 21b1 and 21b2, the stability is high. Even if the coil 1 pushes the blocks 21b1 and 21b2 to move (rotate) in the x direction, the compressive strengths of the blocks 21b1 and 21b2 are large, so that there is no deformation and the movement preventing strength is high.

In addition, the above-described packaging box is a measuring box in which any one coil 1 is accommodated, but a plurality of coils are used as one cylinder by making the packaging box 21 and the blocks 21b1 and 21b2 long in the y direction. It is arranged to be arranged so that they are stored together. In this embodiment, the length of the packaging box in the y direction is determined depending on how many coils are collectively stored.

12A shows a longitudinal section of an example in which packaging boxes 23 to 26 for storing five coils 1 collectively in a large packaging box 27, and FIG. 12B shows a cross section.

The coil 1 described above is taken out of the packaging box 1 by the user and mounted on the welding machine using the wire feed adapter 5.

Fig. 13 shows only the elements of the wire feed adapter 5 with the detachable flange 5fr taken out from the flanged body 5b + 5ff, and the body end of the flanged body 5b + 5ff in that state.
