Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a universal wire feeder. Background Art

[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials by heating, high temperature or high pressure. : It mainly includes arc welding, gas welding, resistance welding, solid phase welding, brazing, etc. It is an important technology in modern manufacturing process. Among them, the wire feeder plays a vital role in arc welding, laser brazing and other processes that require a wire supply system. The wire feeder is mainly composed of wire feed drive, wire feed hose, wire feed wheel and other parts. Its function is to pull and transport the welding wire, ensure that the welding wire can be stably and accurately delivered to the welding area, provide solder and welding gun for welding, which can directly affect the welding efficiency.

[0003] Traditional wire feeders feed wire through two wire feeding wheels. The welding wire is clamped between the two wire feeding wheels and is in line contact with the wire feeding wheels. There is sliding friction during wire feeding. High friction can easily cause deformation of the welding wire and problems such as roughening. 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 that require adjusting the wire feeding angle, position or long wire feeding distance, this can only be achieved by moving or adding wire feeders. This has low flexibility, complex structure, and is even more difficult to achieve when space is limited. Summary of the invention

[0005] In view of this, the present invention provides a universal wire feeder, which aims 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, and easy deformation and roughening of the welding wire.

[0006] To achieve the above purpose, the technical solution of the present invention is as follows:

[0007] A universal wire feeder, comprising a wire feeder body, the wire feeder body comprising a mounting bracket and two rows of wire feeding rollers rotatably arranged in the mounting bracket, the radial side walls of the two rows of wire feeding rollers facing each other, and a gap channel is formed between the two rows of wire feeding rollers, and the gap channel is 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 head and tail of the ball head and the ball socket to change the direction of the welding 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 to each other, and a mounting gap is formed between the first bracket and the second bracket, and two rows of wire feeding rollers are arranged vertically and parallelly in the mounting gap. The above structure is adopted to facilitate the installation of the wire feeding 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] As a preference, 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 a hemispherical groove, and the grooves of the first bracket and the second bracket together constitute 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] As a preferred embodiment, 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 bracket and the second bracket both include a vertical plate and a panel perpendicular to the vertical plate, the panel is parallel to the length direction of the vertical plate and extends outward from the middle of the vertical plate, and a plurality of reinforcing ribs are arranged between the vertical plate and the panel. The above structure is simple and compact, and the strength of the wire feeding mechanism is ensured.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The universal wire feeder provided by the present invention has two rows of wire feeding rollers arranged in parallel, and 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 transport the welding wire. There is rolling friction between the welding wire and the wire feeding roller, and the friction force is small, thereby reducing the problems of welding wire deformation and burrs.

[0020] 2. The wire feeding mechanism is provided with an articulated ball head and ball socket at both ends. Multiple wire feeding mechanisms can be articulated 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, and the installation gap between the first bracket and the second bracket naturally forms a channel for passing the welding wire, which has a simple structure and is easy to install.

[0029] The present invention is further described below in conjunction with embodiments and drawings.

[0030] like Figure 1 , 2 and Figure 4 As shown, a universal wire feeder, the wire feeder 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. Figure 6 As 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. Rolling friction occurs during wire feeding, and the friction force is small, which can reduce the deformation and roughening 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 a mounting 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 in parallel up and down in the mounting gap 231.

[0032] In this embodiment, Figure 3 and Figure 5 As shown, one end of the first bracket 23 and the second bracket 24 both have a protrusion 242 of a trihedral structure, and the protrusions 242 of the first bracket 23 and the second bracket 24 together constitute 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 constitute the ball socket 22. The ball head 21 is hemispherical, and the ball socket 22 can wrap and limit the ball head 21. The ball head 21 and the ball socket 22 cooperate to enable multiple wire feeder bodies A to be connected 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 for passing the welding wire 3 is provided in the ball head 21, and a second channel c for passing the welding wire 3 is provided in the ball socket 22, and both the first channel b and the second channel c are connected to the gap channel a. In this embodiment, the middle of the installation gap 231 between the two vertical plates 231 is the gap channel a, the first channel b is corresponding to the end position of the ball head 21, and the second channel c is corresponding to the end position of the ball socket 22. The structure is simple, and the welding wire 3 is less obstructed during the transportation process.

[0034] like Figure 1 and Figure 6 As 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 direction of the vertical plate 241, and extends outward from the middle position of the vertical plate 241. A triangular reinforcing rib 233 is provided between the vertical plate 231 and the panel 232 at a position corresponding to the installation of the wire feeding roller 1. The structure is compact and can ensure the strength of the wire feeder 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 through the inclined surface 2a, which can increase the angle adjustment range between the two wire feeder bodies A and avoid being restricted.

[0035] like Figure 7As shown, the two wire feeder 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 of the ball head 21 and the ball socket 22, there must be a through portion between the first channel b and the second channel c at the hinge position through which the welding wire 3 can be passed. The two wire feeder bodies A can be in any position within the allowable range of the ball head 21 and the ball socket 22. Multiple wire feeder 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, and such changes all fall within the scope of protection of the present invention.
