Description

Technical Field

[0001] This utility model relates to the field of wire feeder technology, and in particular to a wire feeding device for a gas shielded welding machine. Background Technology

[0002] A wire feeder is a device used in welding processes to automatically and continuously deliver welding wire to the welding area. It typically consists of a motor, reducer, wire feed rollers, clamping mechanism, and wire guide tube. The motor drives the wire feed rollers to rotate via the reducer. The wire feed rollers, in conjunction with the clamping mechanism, clamp the welding wire and feed it out at a set speed and feed rate. The wire is then accurately delivered to the welding arc via the wire guide tube, ensuring a stable supply of welding wire during the welding process and thus achieving high-quality welding. Wire feeders are widely used in various arc welding methods, such as CO2 gas shielded welding, TIG welding, and submerged arc welding.

[0003] In related technologies, during the feeding of welding wire, there may be impurities such as rust on the surface of the welding wire. During feeding, debris is easily generated and adheres to the equipment, thereby contaminating the internal environment of the wire guide tube and affecting the subsequent welding effect. In addition, different welding wires use different wire rolls, but existing equipment cannot easily and quickly replace the wire rolls, which greatly affects work efficiency.

[0004] Therefore, we propose a wire feeding device for gas shielded welding machines to solve the above problems. Utility Model Content

[0040] In this embodiment, the cleaning mechanism includes a cleaning tube 10 and four annular blades 11. The cleaning tube 10 is fixedly installed on one side of the motor box 3, and four annular blades 11 are fixedly installed on the inner side of the cleaning tube 10 to facilitate cleaning of the welding wire surface.

An auxiliary pressure roller 7 and a welding wire pressure roller 8 are respectively sleeved on the two pressure roller shafts 6, which can facilitate the adjustment of the positions of the auxiliary pressure roller 7 and the welding wire pressure roller 8.

[0042] In this embodiment, the auxiliary pressure roller 7 is in contact with the auxiliary winding roller 12, and the welding wire pressure roller 8 is in contact with the welding wire coil 13, which facilitates the compression of the welding wire and prevents it from deviating.

[0043] In this embodiment, a cylinder 9 is fixedly installed on one side of the motor box 3. The output end of the cylinder 9 is in contact with the pressure roller bracket 5, so that the pressure roller bracket 5 can be moved by the cylinder 9.

[0044] In this embodiment, a motor chamber is provided on the inner side of the motor box 3. Two servo motors 14 are fixedly installed on one inner wall of the motor chamber. The output shafts of the two servo motors 14 are fixedly connected to the auxiliary roller 12 and the sleeve base 15 respectively. The two servo motors 14 can drive the auxiliary roller 12 and the sleeve base 15 to rotate respectively.

[0045] In this embodiment, the replacement mechanism includes a guide ring 16, a threaded rod 17, a linkage base 18, and a support assembly. The guide ring 16 is fixedly installed on one side of the sleeve base 15. Six guide grooves are opened on one side of the guide ring 16. A threaded groove is opened on the inner side of the sleeve base 15. The threaded rod 17 is threadedly connected to the threaded groove. The linkage base 18 is rotatably sleeved on the outer side of the threaded rod 17. A support assembly is provided on one side of the linkage base 18. The linkage base 18 can be moved by the threaded rod 17.

[0046] In this embodiment, the support assembly includes six support blocks 19, six linkage metal blocks 20, and six extrusion metal blocks 21. Support blocks 19 are slidably installed on the inner side of each of the six guide grooves. One side of each of the six support blocks 19 is in contact with the inner wall of the same welding wire roll 13. Linkage metal blocks 20 are fixedly installed on one side of each of the six support blocks 19. Linkage grooves are opened on one side of each of the six linkage metal blocks 20. Extrusion metal blocks 21 are fixedly installed on each of the six ends of the linkage base 18. Each of the six extrusion metal blocks 21 is in contact with the corresponding linkage metal block 20. Linkage protrusions are provided on one side of each of the six extrusion metal blocks 21. The six linkage protrusions are slidably installed in the corresponding linkage grooves, so as to facilitate the movement of the corresponding linkage metal blocks 20 by the six extrusion metal blocks 21.

[0047] Working Principle: During wire feeding, the appropriate wire coil 13 is selected based on different requirements. The wire coil 13 is then placed on the support assembly. The operator rotates the threaded rod 17 using a screwdriver. The threaded rod 17 is threadedly connected to the sleeve base 15. Since the sleeve base 15 is fixedly connected to the output shaft of the servo motor 14, and the servo motor 14 has a self-locking property, the sleeve base 15 cannot rotate. The threaded rod 17 moves axially, causing the linkage base 18 to move. The linkage base 18 then moves six extrusion metal blocks 21, which in turn extrude pressure onto the corresponding linkage metal blocks 20. This movement of the six linkage metal blocks 20 causes the corresponding support blocks 19 to move. All six support blocks 19 are slidably installed in the corresponding guide grooves on one side of the guide ring 16. Therefore, the six support blocks 19 come into contact with the inner wall of the wire coil 13, thus... Internal support is achieved, so when the servo motor 14 rotates, the replacement mechanism can drive the wire coil 13 to rotate, thereby conveying the welding wire. When conveying the welding wire, the operator controls the pressure roller mechanism to apply appropriate pressure according to the different types of welding wire to prevent the welding wire from deviating during the conveying process. The cylinder 9 starts and drives the pressure roller bracket 5 to move. The movement of the pressure roller bracket 5 drives the two pressure roller shafts 6 to move, thereby driving the auxiliary pressure roller 7 and the welding wire pressure roller 8 to apply appropriate pressure to the auxiliary winding wheel 12 and the welding wire coil 13 to prevent the welding wire from deviating. When the welding wire on the welding wire coil 13 is conveyed to the auxiliary winding wheel 12, it will be cleaned through the cleaning tube 10. When the welding wire passes through the cleaning tube 10, the annular blade 11 will clean its surface to prevent impurities and rust on it from contaminating the wire guide tube 4, thereby affecting the welding effect. After the welding wire is cleaned, it will be conveyed into the wire guide tube 4 through the auxiliary winding wheel 12 for subsequent work.

[0048] The technological advancements of this invention compared to existing technologies are as follows: the surface of the welding wire fed on the welding wire coil 13 can be cleaned, preventing rust from entering the wire guide tube and causing contamination, thus ensuring subsequent welding quality, increasing the practicality of the equipment, and allowing for convenient and quick replacement of the welding wire coil 13. This enables the wire feeder to adapt to different production needs, greatly improving work efficiency and increasing the applicability of the equipment.
