Description

  The present invention relates to an apparatus for preventing tangling of a welding wire.

  In general, in order to improve the efficiency of welding work, a welding wire stored in a large-capacity welding wire storage container is widely used so that continuous welding can be performed.

  FIG. 1 is a partial cutaway perspective view illustrating a wire storage container equipped with a conventional welding wire tangling prevention device, and FIG. 2 is a drawing of a welding wire pulled out from a wire storage container equipped with a conventional welding wire tangling prevention device. FIG.

  Referring to FIGS. 1 and 2, the welding wire W is wound and stored in a cylindrical wire storage container 400. The wound welding wire W forms a cylindrical welding wire winding body 200 in the wire storage container 400.

  The welding wire W is pulled out through the hollow portion of the welding wire winding body 200, and the welding wire W is continuously supplied to the welding apparatus.

  The welding wire W is twisted in the wire storage container 400 during winding and is wound and stored in a spiral shape. Accordingly, when the welding wire W is pulled out, the elastic recovery is restored to the original state, so that the welding wire W is pulled out while being twisted.

  If the wound welding wire W is not controlled while being twisted, the wire W pulled out while elastically recovering and the subsequent wire W ′ may jump simultaneously and get entangled with each other.

  Therefore, by mounting and holding the ring-shaped welding wire entanglement preventing device 100 at the upper end of the welding wire winding body 200, the drawn-out welding wire W and its subsequent wire W ′ are prevented from jumping up at the same time and entangled with each other. It is.

  Since the welding wire squeezing prevention device 100 is formed in one ring shape, when the welding wire W is pulled out, the welding wire squeezing prevention device 100 receives resistance from the whole. Therefore, the welding wire W may not be pulled out easily and stably from the wire storage container 400.

  Further, even if the welding wire W is pulled out overcoming the pulling resistance, when the welding wire W is pulled out, the entanglement preventing device 100 is pulled up slightly from the welding wire. At this time, the portion of the welding wire W to be drawn out and the welding wire W ′ of the subsequent portion thereof may be drawn at the same time and entangled with each other.

  As described above, there is a case where the welding wire W is difficult to be stably supplied to the welding apparatus, and there is a limit in obtaining an excellent weld bead shape because the drawing resistance when drawing the wire is large. It was.

  In order to solve the above-mentioned various problems, an object of the present invention is to prevent the welding wire from becoming entangled so that when the welding wire is pulled out from the wire storage container, the pulling-out resistance is reduced and can be easily pulled out. Is to provide.

  Another object of the present invention is to provide an apparatus for preventing entanglement of a welding wire that can prevent the welding wires that are subsequently drawn out when the welding wire is drawn out from being simultaneously drawn and entangled with each other.

  In order to achieve the above object, according to one embodiment of the present invention, a wire pressing member mounted on an upper end surface of a welding wire winding body stored in a wire storage container, and positioned inside the wire pressing member. A wire guide member for guiding a welding wire drawn from the welding wire winding body, and two or more connecting the wire pressing member and the wire guide member so that the wire pressing member and the wire guide member move independently. The connecting member is included.

  The wire pressing member or the wire guide member may have a ring shape.

  The inner edge of the wire pressing member and the outer edge of the wire guide member may be spaced apart.

  The lower surface of the wire guide member can be curved so that the pull-out resistance is reduced when the welding wire W is pulled out.

  Each of the connecting members may be made of an elastic material.

  Each of the connecting members may be connected to the upper surface of the wire pressing member and the upper surface of the wire guide member.

  The wire pressing member and the wire guide member can be loosely connected by the connecting members.

  A hollow is formed at the center of the wire winding body, and the wire guide member can be disposed in the hollow of the wire winding body.

  The wire storage container may further include two or more lifting guides disposed in the vertical direction and movably coupled to the wire pressing member.

  The lifting guide is disposed in a space between the inner surface of the wire storage container and the outer surface of the wire winding body, and restrains the upper side of the wire winding body to prevent the welding wire of the wire winding body from jumping up. be able to.

  The elevating guide may be formed in a band shape, and both end portions of the elevating guide may be fixed to the upper and lower sides of the wire storage container.

  A passage groove may be formed in the wire pressing member so that the lifting guide is inserted.

  Hereinafter, preferred embodiments of the present invention in which the objects of the present invention can be specifically realized will be described with reference to the accompanying drawings.

  FIG. 3 is a partially cut perspective view illustrating a wire container equipped with an embodiment of the welding wire tangling prevention device according to the present invention, and FIG. 4 is a perspective view illustrating the welding wire tangling prevention device. FIG. 3 is a cross-sectional view illustrating an apparatus for preventing tangling from a welding wire.

  3 to 5, the welding wire tangling prevention device 10 is mounted on the upper end surface of the welding wire winding body 20 housed in the wire housing container 40. The welding wire winding body 20 is formed by winding a welding wire W in a spiral shape in a state where a twist is applied during winding in the wire storage container 40. Such a welded wire winding body 20 can be of a cylindrical shape with a hollow formed in the center.

  The welding wire tangling prevention device includes a wire pressing member 11 mounted on an upper end surface of the welding wire winding body 20 so as to press the welding wire winding body 20 wound around the wire storage container 40, and the wire pressing member. A wire guide member 12 that is positioned inside the member 11 and that guides the welding wire W drawn from the welding wire winding body 20, and the wire pressing member 11 and the wire guide member 12 so that the wire pressing member 11 and the wire guide member 12 move independently. 11 and the wire guide member 12 may be included.

  Therefore, it is possible to prevent the welding wire from jumping up due to elastic recovery by the wire pressing member 11 and the connecting member 13 positioned on the upper end surface of the wire winding body 20. Further, since the wire guide member 12 is installed so as to be able to move independently of the wire pressing member 11, the wire guide member is used when the welding wire W is drawn into the hollow portion of the welding wire winding body 20. Only 12 can be in contact with the wire being drawn. Therefore, the welding wire W can be pulled out from the wire storage container 40 in a state in which the pulling resistance is greatly reduced.

  The wire pressing member 11 and the wire guide member 12 can each be formed in a ring shape. By forming the wire pressing member 11 in a ring shape, the upper end portion of the cylindrical wire winding body 20 can be sufficiently pressed. Further, since the inner peripheral surface of the wire guide member 12 is formed in a circular shape, the pulling resistance of the welding wire drawn from the wire winding body 20 is reduced, and the welding wire W can be drawn smoothly.

  In addition, the inner edge of the wire pressing member 11 and the outer edge of the wire guide member 12 can be separated from each other. At this time, since the inner diameter of the wire pressing member 11 is larger than the outer diameter of the wire guide member 12, the wire guide member 12 can be positioned inside the wire pressing member 11.

  The wire pressing member 11 and the wire guide member 12 can be loosely connected by a connecting member 13 made of a flexible material. Therefore, even when the wire guide member 12 is moved by the pulling force of the welding wire W when the welding wire W is pulled out, the wire pressing member 11 does not move. Therefore, the upper end portion of the wire winding body 20 is continuously pressed, so that the welding wire W of the wire winding body 20 can be prevented from jumping up due to elastic recovery.

  Any flexible material can be applied to the connecting member 13. Since the connecting member 13 is formed of an elastic material having elasticity (stretchability), the wire guide member 12 and the wire pressing member 11 can be moved more naturally and independently. An elastic band form having a certain width can be applied to such a connecting member.

  The shape of the wire pressing member 11 and the wire guide member 12 and the shape or connecting position of the connecting member 13 can be variously changed.

  The wire pressing member 11 is located close to the inner wall of the wire storage container 40, and the wire guide member 12 is located close to the center side of the wire storage container 40. Therefore, when the welding wire W is not pulled out, the wire pressing member 11, the connecting member 13, and the wire guide member 12 press the wire winding body 20, so that the welding wire W is elastically recovered from the welding wire winding body 20. To prevent jumping up.

  The wire pressing member 11 and the wire guide member 12 can be installed so as to descend when the welding wire W is drawn from the upper end surface of the wire winding body 20. At this time, the outer edge of the wire pressing member 11 is separated from the inner surface of the wire container 40 by a predetermined distance. Therefore, even if the height of the wire winding body 20 is lowered by pulling the welding wire W from the wire winding body 20, the wire pressing member 11 and the wire guide member 12 are connected to the wire winding body 20. Continue to hold the top edge.

  The operation of the embodiment of the present invention configured as described above will be described.

  FIG. 6 is a cross-sectional view showing the operation when the welding wire is pulled out from the wire storage container.

  Referring to FIG. 6, when the welding wire W is pulled out from the welding wire winding body 20 in the direction of arrow A, the welding wire W is pulled out from the drawn welding wire W and the portion of the wire guide member 12 in contact with the wire W. The force is received in the direction of arrow B in FIG.

  At this time, since the drawn out welding wire W and the portion of the wire guide member 12 in contact with the wire W are lifted upward, the drawing resistance of the drawn out welding wire W and the wire guide member 12 is reduced.

  Further, the wire guide member 12 on the opposite side of the drawn welding wire W moves to the center side of the wire storage container 40. At this time, the wire guide member 12 on the opposite side is lowered to the hollow portion of the welding wire winding body 20. Therefore, the wire guide member 12 and the connecting member 13 on the opposite side are pressed while wrapping the welding wire winding body 20. At this time, it is possible to prevent the welding wire W in the subsequent portion that should not be drawn out from being drawn and entangled with the welding wire W portion to be drawn out.

  The shape of the weld bead can be made beautiful by preventing the welding wire from being entangled as described above and being drawn out smoothly.

  Next, another embodiment of the welding wire tangling prevention device according to the present invention will be described.

  FIG. 7 is a cross-sectional view illustrating still another embodiment of the welding wire entanglement preventing device according to the present invention.

  Referring to FIG. 7, the wire guide member 12 can be disposed in the hollow of the wire winding body 20. At this time, the lower surface of the wire guide member 12 may be disposed below the upper end surface of the wire winding body 20.

  Since the wire guide member 12 is disposed in the hollow of the wire winding body 20, the connecting member 13 presses the upper end portion of the inner peripheral surface of the wire winding body 20. This structure can more strongly press the upper end portion of the inner peripheral surface of the wire winding body 20 than the structure in which the wire guide member 12 is disposed on the upper surface of the wire winding body 20. Therefore, it is possible to prevent the welding wire W from being unwound and entangled from the inner peripheral surface side of the wire winding body 20.

  FIG. 8 is a cross-sectional view illustrating another embodiment of the welding wire entanglement preventing device according to the present invention.

  Referring to FIG. 8, the lower surface of the wire guide member 12 may be formed to be curved. Accordingly, when the welding wire W is pulled out from the wire storage container 40, the drawing resistance of the welding wire W can be further reduced by the lower surface of the wire guide member 12. Therefore, the welding wire W can be pulled out more easily.

  Except for the above-described configuration, the description is omitted because it is substantially the same as the above-described tangling prevention device.

  Next, another embodiment of the welding wire tangling prevention device according to the present invention will be described.

  FIG. 9 is a cross-sectional view illustrating still another embodiment of the welding wire tangling prevention device according to the present invention.

  Referring to FIG. 9, the connecting member 13 may be connected to the upper surface of the wire pressing member 11 or the wire guide member 12. At this time, since the connecting member 13 is separated from the upper end surface of the welding wire winding body 20 (see FIG. 6), the connecting member 13 can be prevented from acting on the pulling resistance of the welding wire W.

  The connecting member 13 can be connected to either the lower surface, the side surface, or the upper surface of the wire pressing member 11 or the wire guide member 12. When the connecting member 13 is connected to the lower surface of the wire pressing member 11 or the wire guide member 12, there is a possibility that it acts as a pulling resistance of the welding wire W. However, the upper end surface of the welding wire winding body 20 is more stable. I can hold it down.

  Except for the above-described configuration, the description is omitted because it is substantially the same as the above-described tangling prevention device.

  Next, another embodiment of the welding wire tangling prevention device according to the present invention will be described.

  FIG. 10 is a perspective view showing still another embodiment of the welding wire tangling prevention device according to the present invention, and FIG. 11 is a cross-sectional view showing a state where the welding wire tangling prevention device is mounted on the wire storage container.

  Referring to FIGS. 10 and 11, the welding wire entanglement preventing device includes a wire pressing member 11, a wire guide member 12, a connecting member 13, and a lifting guide 30.

  Since the wire pressing member 11, the wire guide member 12, and the connecting member 13 are substantially the same as those described in the above-described embodiment, the description thereof is omitted.

  The elevating guide 30 is disposed in the wire storage container 40 in the vertical direction. The wire pressing member 11 is coupled to the elevating guide 30 so as to move up and down. At this time, a passage groove 14 through which the lifting guide 30 can pass can be formed on the outer periphery of the wire pressing member 11.

  One side of the elevating guide 30 is fixed to the upper end portion of the inner wall of the wire storage container 40, and the other side of the elevating guide 30 is fixed to the lower end portion of the inner wall of the wire storage container 40. Such an elevating guide extends from the upper end portion of the wire storage container 40 to the lower end portion. Such a lifting guide can be formed in a band form.

  Typically, two or more lifting guides 30 can be installed in the wire storage container 40. At this time, the elevating guides 30 can be arranged at almost the same intervals along the circumferential direction of the wire storage container 40.

  The lifting guide 30 may be disposed in a space between the inner surface of the wire storage container 40 and the outer surface of the wire winding body 20. At this time, since the elevating guide 30 restrains the upper part of the wire winding body 20, it is possible to fundamentally prevent the welding wire W of the wire winding body 20 from jumping to the upper side of the wire winding body 20. .

  When the upper end of the wire winding body 20 is gradually lowered by drawing the welding wire W from the wire winding body 20, the welding wire pressing member 11 of the welding wire entanglement prevention device 10 is lowered according to the lifting guide 30. It becomes like this.

  In addition to the above-described embodiments, it is obvious to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit of the invention. . Accordingly, the foregoing embodiments are illustrative rather than limiting and the invention is thereby not limited to the above detailed description, but may vary within the scope of the above claims and their equivalents.
