Description

Technical Field

[0001] The utility model relates to the technical field of welding wire feeding, in particular to a feeding device for welding wire. Background Art

[0002] During welding, the welding wire is stably supplied through the feeding device, which reduces manual operation and provides a more stable feeding effect.

[0003] In the existing technology, the welding wire is generally fed by clamping the welding wire through an actively rotating feed roller group, and the output welding wire is guided and limited by a straight tube structure such as a guide tube, so that the end of the welding wire is aligned with the welding position. The feed roller group and the guide tube can straighten the welding wire to facilitate alignment. However, different operators have different welding habits and operating angles. Even if the machine performs welding operations, different welding angles need to be designed according to different products. Therefore, when the welding wire is output, it is necessary to be able to adjust the angle with a high degree of freedom. The single straight line output after straightening cannot adapt well to different welding spaces.

[0004] In the prior art, the problem of inconvenience in adjusting the output angle of the welding wire needs to be solved. Utility Model Content

[0038] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] like Figure 1-8 As shown, a feeding device for welding wire includes: a base 1; a box shell 2, which has a feed port 201 on one side, and the box shell 2 is rotatably arranged in a vertical plane relative to the base 1, and the box shell 2 is used to accommodate a welding wire reel 8; a discharge roller group 3, which has a plurality of rotatable rotating rollers 301, and the discharge roller group 3 is located on one side of the box shell 2 and is used to feed the welding wire; a discharge pipe 4, which is located next to the discharge roller group 3, and the discharge pipe 4 rotates with the box shell 2, and the welding wire passes through the discharge roller group 3 and then out of the discharge pipe 4.

[0040] During use, a welding wire is wound around the wire reel 8, which is rotatably mounted within the housing 2. The discharge roller assembly 3 may include two rotating rollers 301 or four rotating rollers 301, and the welding wire passes between the two rotating rollers 301. When four or more rotating rollers 301 are provided, the welding wire can be better straightened. One of the rotating rollers 301 can be directly driven by a drive motor to provide power for the output of the welding wire. After the welding wire passes through the discharge roller assembly 3 and the discharge pipe 4 in sequence, it is aligned with the position to be welded. The housing 2 is rotated, and the housing 2 rotates within a vertical plane to adjust the output angle of the welding wire, ultimately aligning the end of the welding wire with the welding position.

[0041] The axis of the discharge pipe 4 can be positioned opposite to the two rotating rollers 301 in the discharge roller group 3. As shown in the figure, the feed port 201 can be set on the left side of the box shell 2, and the discharge pipe 4 can be located in front of the box shell 2. A hole can be opened on the front side wall of the box shell 2 for passing the welding wire rod.

[0042] Furthermore, the base 1 has a column 101 with a vertically arranged chute 1011 on the column 101, and the box housing 2 is arranged to rise and fall and rotate on the chute 1011.

[0043] During use, the housing 2 rotates vertically to adjust the wire delivery angle, and the lifting mechanism facilitates height adjustment, better adapting to different welding spaces. The threaded post 202 rotates or rises within the chute 1011, driving the housing 2 to rotate or rise. The locking bolt can then be threadedly connected to the threaded post 202 to lock and position the housing 2, maintaining its angle and height. The column 101 is positioned between the locking bolt and the housing 2, with one side of the housing 2 abutting against one side of the column 101, and the locking bolt abutting against the other side of the column 101.

[0044] The assembly further includes: a mounting plate 6, which is plugged into the outside of the casing 2 and has a feed hole 601 that communicates with the interior of the casing 2. The welding wire passes through the feed hole 601 and the discharge roller assembly 3 in sequence. The discharge roller assembly 3 is rotatably mounted on the mounting plate 6. The mounting plate 6 has a bracket 602; a mounting frame 603 that is rotatably mounted on the bracket 602, and the discharge pipe 4 is mounted on the mounting frame 603. The upper end of the casing 2 has a plurality of plug-in posts 203, and the mounting plate 6 has plug-in holes that plug into the plug-in posts 203.

[0045] During use, the discharge roller group 3 and the discharge pipe 4 are arranged on the box shell 2 via the mounting plate 6, and the mounting plate 6 is plugged in to achieve removable and interchangeable configuration, which facilitates changing the discharge direction of the welding wire. For example, holes can be opened on both the front and rear sides of the box shell 2 for discharging the welding wire, and the mounting plate 6 can be installed on the front or rear side of the box shell 2. The mounting plate 6 can be roughly in the shape of an inverted "L", which facilitates stable hanging and plugging on the box shell 2. The mounting bracket 603 can be tilted and arranged on the lower side of the mounting plate 6, and the mounting pipe is installed at the end of the mounting bracket 603. The mounting bracket 603 can be in the shape of a "U", fixed in the middle of the discharge pipe 4, so that the discharge pipe 4 can rotate in a vertical plane relative to the box shell 2, which facilitates fine-tuning the output angle at the end of the welding wire, making adjustment more convenient and quick.

[0046] A plurality of plug-in posts 203 may be provided on the upper end of the box shell 2 and distributed in different positions, such as the front and rear sides of the upper end of the box shell 2, to facilitate the installation of the mounting plate 6 on the front or rear side.

[0047] Furthermore, the wire reel 8 has a through hole 801 in the middle, and the base 1 has mounting grooves on the upper and lower sides; it also includes: two bayonet pins 7, each of which is slidably arranged in a bayonet pin 7, and the bayonet pin 7 is used to insert into the through hole 801 of the wire reel 8, and the part of the bayonet pin 7 inserted into the through hole 801 has two opposite inclined surfaces 701, and the wire reel 8 rotates around the bayonet pin 7; there are two compression springs 702, each of which is arranged in a compression spring 702, one end of the compression spring 702 acts on the box shell 2, and the other end acts on the bayonet pin 7, and is used to provide force for the bayonet pin 7 to be inserted into the through hole 801.

The upper and lower latches 7 are respectively inserted into the upper and lower sides of the through hole 801 in the middle of the wire reel 8 for positioning. The portion of the latch 7 inserted into the through hole 801 can be a cylinder, with inclined surfaces 701 provided on the left and right sides of the cylinder. The latch 7 can serve as the rotation axis of the wire reel 8. The upper portion of the latch 7 can be a polygon such as a triangle or a quadrilateral, or a guide can be provided to prevent the latch 7 from rotating during lifting. The two inclined surfaces 701 of the latch 7 are always located in the assembly and disassembly direction of the wire reel 8, that is, one of the inclined surfaces 701 is opposite to the feed port 201. When the wire reel 8 is inserted and removed, it is guided by the inclined surface 701.

[0049] Furthermore, there are two box shells 2, which are respectively arranged on both sides of the column 101, and the two box shells 2 are distributed up and down.
