Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to an articulated roller wire feeding mechanism. Background Art

[0002] Welding is a manufacturing process and technology that uses heat, high temperature or high pressure to join metals or other thermoplastic materials. : Arc welding, including gas welding, resistance welding, solid-phase welding, and brazing, is a crucial technology in modern manufacturing. Wire feeders play a crucial role in processes like arc welding and laser brazing that require a wire feed system. Wire feeders primarily consist of a wire drive, wire feed hose, and wire feed rolls. Their function is to pull and transport the welding wire, ensuring it is stably and accurately delivered to the welding area. This provides solder for the welding torch, directly impacting welding efficiency.

[0003] Traditional wire feeders feed wire through two wire feeding rollers. The welding wire is clamped between the two wire feeding rollers and is in line contact with the wire feeding rollers. There is sliding friction during wire feeding. High friction can easily cause deformation of the welding wire and problems such as hair pulling. In severe cases, the welding wire cannot pass through the conductive nozzle and causes wire blockage, affecting welding efficiency and increasing abnormal downtime.

[0004] In addition, most traditional wire feeding mechanisms can only pull the welding wire in a single direction. For complex situations where the wire feeding angle, position or long wire feeding distance needs to be adjusted, this can only be achieved by moving or adding wire feeders. This has low flexibility, a complex structure, and is even more difficult to achieve when space is limited. Utility Model Content

[0005] In view of this, the utility model provides an articulated roller wire feeding mechanism, the purpose of which is to increase the flexibility of the wire feeding mechanism and solve the problems of large friction between the welding wire and the wire feeding wheel, which easily cause welding wire deformation and hair pulling.

[0006] To achieve the above purpose, the technical solution of this utility model is as follows:

[0007] An articulated roller wire feeding mechanism comprises a wire feeding mechanism body, the wire feeding mechanism body comprising a mounting bracket and two rows of wire feeding rollers rotatably disposed within the mounting bracket, the radial side walls of the two rows of wire feeding rollers facing each other, and a gap channel formed between the two rows of wire feeding rollers, the gap channel being used to pass welding wire;

[0008] A ball head is provided at one end of the mounting bracket, and a ball socket adapted to the ball head is provided at the other end. A first channel for passing the welding wire is provided in the ball head, and a second channel for passing the welding wire is provided in the ball socket. Both the first channel and the second channel are connected to the gap channel.

[0009] With the above structure, the contact area between the welding wire and the two rows of rollers is small, which reduces the friction on the welding wire and prevents the generation of more burrs and wire blockage. Multiple wire feeding structures can be hinged at the end through the ball head and ball socket to change the direction of wire feeding, which is more flexible.

[0010] Preferably, the mounting bracket includes a first bracket and a second bracket, the first bracket and the second bracket are arranged opposite each other with a mounting gap formed therebetween, and the two rows of wire feed rollers are arranged vertically and parallelly within the mounting gap. The above structure facilitates the installation of the wire feed rollers.

[0011] Preferably, one end of each of the first bracket and the second bracket has a hemispherical protrusion, and the protrusions of the first bracket and the second bracket together constitute the ball head. The above structure facilitates the articulation between the two wire feeding mechanisms.

[0012] Preferably, the first channel is arranged between the two protrusions. With the above structure, the structure is simple and the welding wire is not easily blocked.

[0013] Preferably, the other ends of the first bracket and the second bracket are both provided with hemispherical grooves, and the grooves of the first bracket and the second bracket together form the ball socket. The above structure facilitates the articulation between the two wire feeding mechanisms.

[0014] Preferably, the second channel is arranged between the two grooves. With the above structure, the structure is simple and the welding wire is not easily blocked.

[0015] Preferably, the ball head at the end of the mounting bracket is connected to the middle position of the mounting bracket via an inclined plane. With the above structure, the angle adjustment range between the two wire feeding mechanisms is increased to prevent interference.

[0016] Preferably, an annular groove is provided on the circumferential outer wall of the wire feeding roller, and the gap channel is formed between the annular grooves of the two facing wire feeding rollers. With the above structure, the welding wire is confined in the gap channel.

[0017] Preferably, the first and second brackets each include a vertical plate and a panel perpendicular to the vertical plate. The panel is parallel to the length of the vertical plate and extends outward from the middle of the vertical plate. A plurality of reinforcing ribs are provided between the vertical plate and the panel. This structure is simple and compact, ensuring the strength of the wire feeding mechanism.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The utility model provides an articulated roller wire feeding mechanism, in which two rows of wire feeding rollers are arranged in parallel. An annular groove is provided on the circumferential outer wall of the wire feeding roller. The welding wire is continuously rotated by the roller to feed the welding wire. There is rolling friction between the welding wire and the wire feeding roller, and the friction force is small, which reduces the problem of welding wire deformation and burrs.

[0020] 2. The wire feeding mechanism is equipped with a hinged ball head and ball socket at both ends. Multiple wire feeding mechanisms can be hinged head to tail to change the feeding direction of the welding wire, making the wire feeding flexible.

[0021] 3. The wire feeding roller is installed between the first bracket and the second bracket. The installation gap between the first bracket and the second bracket naturally forms a channel for passing the welding wire. The structure is simple and the installation is convenient.

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] like Figure 1 、 2 and Figure 4 As shown, an articulated roller wire feeding mechanism, the wire feeding mechanism body A is composed of a mounting bracket 2 and two rows of wire feeding rollers 1 rotatably arranged in the mounting bracket 2, each row of wire feeding rollers 1 has four wire feeding rollers 1, and the radial side walls of the two rows of wire feeding rollers 1 are opposite to each other, as shown in FIG. Figure 6As shown, an annular groove 11 is provided on the circumferential outer wall of the wire feeding roller 1, and a gap channel a is formed between the annular grooves 11 of the two opposite wire feeding rollers 1. The welding wire 3 passes through the gap channel a and can be confined between the annular grooves 11. The wire feeding roller 1 continuously rotates to transport the welding wire 3. There is point contact between the welding wire 3 and the wire feeding roller 1. When feeding the wire, there is rolling friction, and the friction force is small, which can reduce the deformation and hair pulling problems of the welding wire 3.

[0031] The mounting bracket 2 includes a first bracket 23 and a second bracket 24. The first bracket 23 and the second bracket 24 each include a vertical plate 231. One end face of the vertical plate 231 is a vertical plane. The vertical planes of the first bracket 23 and the second bracket 24 are opposite to each other. The first bracket 23 and the second bracket 24 are connected by bolts, and an installation gap 231 is formed therebetween. The rotating shafts of the two rows of wire feeding rollers 1 are fixed to the two vertical plates 231 and are arranged parallel to each other in the installation gap 231.

[0032] In this embodiment, Figure 3 and Figure 5 As shown, one end of each of the first bracket 23 and the second bracket 24 has a protrusion 242 with a trihedral structure, and the protrusions 242 of the first bracket 23 and the second bracket 24 together form the ball head 21. The other end is provided with a groove 243 adapted to the protrusion 242, and the grooves 243 of the first bracket 23 and the second bracket 24 together form the ball socket 22. The ball head 21 is hemispherical, and the ball socket 22 can wrap and restrict the ball head 21. The cooperation between the ball head 21 and the ball socket 22 can connect multiple wire feeding mechanism bodies A end to end within a certain angle range, change the direction of feeding the welding wire 3, and improve the flexibility of wire feeding.

[0033] like Figure 4 As shown, a first channel b is defined within the ball head 21 for threading the welding wire 3, and a second channel c is defined within the ball socket 22 for threading the welding wire 3. Both the first channel b and the second channel c are connected to the gap channel a. In this embodiment, the gap channel a is defined in the middle of the installation gap 231 between the two vertical plates 231, the first channel b corresponds to the end of the ball head 21, and the second channel c corresponds to the end of the ball socket 22. This simple structure minimizes obstruction to the welding wire 3 during transport.

[0034] like Figure 1 and Figure 6As shown, the first bracket 23 and the second bracket 24 further include a panel 232 perpendicular to the vertical plate 241. The panel 232 is parallel to the length of the vertical plate 241 and extends outward from the middle position of the vertical plate 241. Triangular reinforcing ribs 233 are provided between the vertical plate 231 and the panel 232, corresponding to the position where the wire feed roller 1 is installed. This compact structure ensures the strength of the wire feed mechanism body A. In this embodiment, the ball head 21 is connected to the panel 232 of the mounting bracket 2 and the vertical plate 241 via an inclined surface 2a, which can increase the angular adjustment range between the two wire feed mechanism bodies A and avoid restrictions.

[0035] like Figure 7 As shown, the two wire feeding mechanism bodies A are hinged to the ball head 21 and the ball socket 22, and the first channel b and the second channel c at the hinge position are spliced. Since the first channel b and the second channel c are respectively located in the middle position of the ball head 21 and the ball socket 22, there must be a through part between the first channel b and the second channel c at the hinge position to allow the welding wire 3 to pass through. The two wire feeding mechanism bodies A can be in any position within the allowable range of the ball head 21 and the ball socket 22. Multiple wire feeding mechanism bodies A are hinged head to tail to realize universal transportation of the welding wire 3.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
