A novel wire feeding device for welding wire

Abstract

A novel wire feeding device for welding wire includes a housing, inside which a transverse moving component is installed. The upper part of the transverse moving component is fixedly connected to the housing. The transverse moving component drives the housing to move laterally. A wire feeding motor is installed inside the housing, and the output shaft of the wire feeding motor is connected to the wire feeding component. While the wire feeding component feeds the wire, the transverse moving component drives the wire feeding component to move synchronously in the opposite direction. The transverse moving component is configured to drive the wire feeding component to move laterally left and right while feeding the wire. The direction of movement is opposite to the direction of the welding wire's offset on the winding roller, thereby ensuring that the welding wire is always aligned with the wire groove of the welding machine, preventing the welding wire from swaying and making it less prone to breakage.

Description

Technical Field

[0001] This utility model relates to the field of welding wire technology, and more specifically to a novel wire feeding device for electric welding wire. Background Technology

[0002] Welding wire is a metal wire used in welding, either as filler metal or simultaneously as a conductive electrode. In gas welding and tungsten inert gas (TIG) welding, the welding wire serves as filler metal; in submerged arc welding, electroslag welding, and other gas metal arc welding, the welding wire is both filler metal and a conductive electrode. The surface of the welding wire is not coated with flux for oxidation prevention.

[0003] When using welding wire, it is usually wound on a roller and welded while the wire is being fed out. This method is more efficient. However, the current wire feeding device has a drawback: because the welding wire is wound on the roller, it swings left and right as the roller rotates during the feeding process. Utility Model Content

[0004] One advantage of this invention is that it provides a novel wire feeding device for welding wire, which is equipped with a transverse component that can drive the wire feeding component to move laterally left and right while feeding the wire. The direction of movement is opposite to the direction of the welding wire offset on the winding roller, thereby ensuring that the welding wire can always be aligned with the wire groove of the welding machine, and the welding wire will not wobble, making it less likely to break.

A wire feeding motor 7 is installed inside the housing 6, and the output shaft of the wire feeding motor 7 is connected to the wire feeding assembly.

The transverse moving assembly includes a bearing seat 18 installed inside the housing 16 and... A transverse motor 3 is installed outside the housing 16.

A nut seat 5 is engaged with the transverse lead screw 4. The upper end of the nut seat 5 extends from the slot to the outside of the housing 16. When the transverse lead screw 4 rotates, the nut seat 5 moves laterally along the slot. Two linear guides 19 are also provided at the upper end of the housing 6. The two linear guides 19 are located in the slot respectively. Both sides; the middle of the lower end of the housing 6 is fixedly connected to the nut seat 5, and both sides of the lower end of the housing 6 are fixedly connected to the movable seats of two linear guide rails 19; the wire feeding assembly includes a rotating shaft 11 fixedly connected to the output shaft of the wire feeding motor 7, a bushing 10 is rotatably provided on the rotating shaft 11, and at least two sets of connecting rods 8 are fixedly provided on the circumferential surface of the bushing 10. A support rod 9 is fixedly provided on the outer end of the connecting rod 8, a fixed baffle 17 perpendicular to the support rod 9 is fixedly provided on one end of the support rod 9, and a locking screw 14 is provided on the other end of the support rod 9. The locking screw 14 has a series of screws from the inside to the outside. A rotating sleeve 12 and a handle 13 are arranged in sequence. The rotating sleeve 12 is connected to the locking screw 14 in a freely rotatable manner. The handle 13 is engaged with the locking screw 14. A movable baffle 15 is fixedly arranged on the circumferential surface of the rotating sleeve 12. The rotation range of the movable baffle 15 does not overlap with the bushing 10 and the rotating shaft 11. A locking groove is provided at the corresponding position of the outer end of the rotating shaft 11 and the bushing 10. A locking block is detachably arranged in the locking groove. When the locking block is inserted into the locking groove, the rotating shaft 11 and the bushing 10 rotate synchronously. When the locking block is not inserted into the locking groove, the bushing 10 can rotate freely on the rotating shaft 11.

[0022] The first embodiment of this utility model is as follows:

[0023] A novel wire feeding device for welding wire includes a housing 16, a base plate 2 fixedly installed on the lower part of the housing 16, and casters 1 at the four corners of the lower part of the base plate 2 to facilitate pushing the wire feeding device. Brakes are also provided on the casters 1.

[0024] A transverse movement assembly is installed inside the housing 16. The transverse movement assembly includes a bearing seat 18 installed inside the housing 16 and a transverse movement motor 3 installed outside the housing 16. The bearing seat 18 and the transverse movement motor 3 are located at opposite ends of the housing 16. The output shaft of the transverse movement motor 3 passes through the housing 16 and is connected to a reducer. The output shaft of the reducer is connected to a transverse movement screw 4. The other end of the transverse movement screw 4 is rotatably connected to the bearing seat 18. A transversely extending slot is provided on the upper surface of the housing 16. The transverse movement screw 4 is located below the slot. A nut seat 5 is engaged with the transverse movement screw 4. The upper end of the nut seat 5 extends from the slot to the outside of the housing 16. When the transverse movement screw 4 rotates, the nut seat 5 moves laterally along the slot. The reducer can slow down the rotation speed of the transverse movement screw 4 to match the rotation speed of the welding wire feeding assembly, ensuring that the extension direction of the welding wire is always perpendicular to the axis of the winding roller.

[0025] It should be noted that both ends of the transverse lead screw 4 have a section of round rod without threads, which are connected to the bearing housing 18 and the output shaft of the reducer.

[0026] The upper end of the housing 6 is also provided with two linear guide rails 19. The two linear guide rails 19 are located on both sides of the slot and in the same direction as the slot. The middle part of the lower end of the housing 6 is fixedly connected to the nut seat 5. The two sides of the lower end of the housing 6 are fixedly connected to the moving seats of the two linear guide rails 19. The linear guide rails 19 can make the lateral movement of the housing 6 more stable. When the transverse motor 3 is working, it drives the transverse lead screw 4 to rotate through the reducer, thereby causing the nut seat 5 to move laterally along the transverse lead screw 4.

[0027] When using welding wire, since the outer coiled welding wire has a larger winding diameter and the inner coiled welding wire has a relatively smaller winding diameter, the transverse motor 3 is a variable frequency motor, which can change the frequency during operation to match the rotation speed of the roller.

[0028] In addition, the welding wire is not consumed quickly during use. In most usage scenarios, the consumption is variable. Therefore, when the welding wire on the roller is laid to the edge and changes direction, the transverse motor 3 also changes its rotation direction at the same time. Since the transverse motor 3 needs a short time to change direction, the welding wire will have a slight offset at this time. However, these slight offsets will not affect the overall technical effect.

[0029] The upper part of the transverse component is fixedly connected to the housing 6. The transverse component drives the housing 6 to move laterally. The housing 6 is equipped with a wire feeding motor 7. The output shaft of the wire feeding motor 7 is connected to the wire feeding component. The wire feeding component includes a rotating shaft 11 fixedly connected to the output shaft of the wire feeding motor 7. A bushing 10 is rotatably provided on the rotating shaft 11. Locking grooves are provided at corresponding positions on the outer ends of the rotating shaft 11 and the bushing 10. The locking grooves are two identical rectangular grooves, respectively provided on the rotating shaft 11 and the bushing 10. When the two rectangular grooves are connected, they form a complete locking groove. A locking block is detachably provided in the locking groove. When the locking block is inserted into the locking groove, the rotating shaft 11 and the bushing 10 are connected as one unit and rotate synchronously. When the locking block is not inserted into the locking groove, the bushing 10 can rotate freely on the rotating shaft 11. Thus, two working modes are possible: one is driven by the wire feeding motor 7, and the other is driven by external force pulling the welding wire.

[0030] Four sets of connecting rods 8 are fixedly arranged on the circumferential surface of the bushing 10. The angle between adjacent connecting rods 8 is 90 degrees. A support rod 9 is fixedly arranged on the outer end of the connecting rod 8. A fixed baffle 17 perpendicular to the support rod 9 is fixedly arranged on one end of the support rod 9. A locking screw 14 is arranged on the other end of the support rod 9. A rotating sleeve 12 and a handle 13 are arranged sequentially from the inside to the outside on the locking screw 14. The rotating sleeve 12 is connected to the locking screw 14 in a freely rotatable manner. The handle 13 is engaged with the locking screw 14. A movable baffle 15 is fixedly arranged on the circumferential surface of the rotating sleeve 12.

[0031] When in use, loosen the handle 13, at which point the rotating sleeve 12 can rotate freely. Rotate the movable baffle 15 to the inside, place the roller with the welding wire on it onto the support structure formed by the four support rods 9, and then rotate the movable baffle 15 to the position corresponding to the fixed baffle 17. Tighten the handle 13 and use the friction between the handle 13 and the rotating sleeve 12 to fix the movable baffle 15.

[0032] Then the wire can be fed out. During the wire feeding process, the machine casing 6 also moves left and right, and the position of the movement corresponds to the position of the welding wire on the winding roller, so that the welding wire is always perpendicular to the axis of the winding roller.

[0033] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments.
