Abstract
Description
Technical Field
[0001] The utility model relates to the field of wire feeding machines, in particular to a crawler type wire feeding mechanism. Background Art
[0002] Welding is a key technology in modern manufacturing. Arc welding is a welding process in which a welding wire is heated and melted by an electric arc, fusing with the base material to form a weld joint. The wire feeder plays a crucial role in this process, directly impacting welding efficiency. The wire feeder primarily consists of a wire drive, wire feed hose, and wire feed rolls. Its function is to pull and transport the welding wire, providing solder for the welding gun.
[0003] Traditional wire feeders feed wire through two sets of wire feed rolls. The welding wire is clamped between the two wire feed rolls, and the contact area between the two wire feed rolls is very small. It is easy for the welding wire to be deformed due to the pressure, which ultimately affects the fit between the welding wire and the hole of the conductive nozzle. If the pressure is reduced by increasing the distance between the two wire feed rolls, it will lead to abnormal wire feeding, especially for softer welding wires, such as copper, aluminum and other softer materials. Utility Model Content
[0004] In view of this, the present invention provides a crawler-type wire feeding mechanism, which aims to solve the problem that the contact area between the wire feeding wheel and the welding wire is small, which causes the welding wire to be easily deformed. To achieve the above purpose, the technical solution of the present invention is as follows:
[0005] A crawler wire feeding mechanism includes two crawler systems and a driver for driving the two crawler systems to rotate in opposite directions. The outer surfaces of one side of the two crawler systems in the length direction are arranged opposite each other, and a gap channel is provided between the two. The gap channel is used for passing the welding wire.
[0006] With the above structure, the contact area between the welding wire and the track is large, the surface of the welding wire is not easily deformed, the contact between the welding wire and the conductive nozzle is better, and the welding process is smoother.
[0007] As a preferred embodiment, the two groups of crawler systems are arranged in an upper and lower manner. With the above structure, the structure is compact and convenient for conveying welding wire.
[0008] Preferably, the crawler system includes a driving wheel, a driven wheel, and a crawler assembly encircled on the driving wheel and the driven wheel, and the driver is used to drive the driving wheel to rotate. The above structure is used to provide power for the crawler.
[0009] Preferably, the driving wheel and the driven wheel are both sprockets, and the track assembly includes a chain mounted on the driving wheel and the driven wheel, the chain being composed of a plurality of hinged links, each of which is fixedly connected to a track shoe. With this structure, a rigid horizontal plane is formed to cooperate with the welding wire.
[0010] Preferably, the driver is a motor, the output shaft of which is connected to the driving wheel to drive the driving wheel to rotate. The above structure is low-cost and provides power for the crawler track.
[0011] Preferably, the outer surface of the track shoe is equipped with an insert having a lower hardness than the welding wire. This structure creates a "wrapping" effect on the welding wire, increasing the contact area with the wire, thereby improving welding efficiency and reducing downtime.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] 1. The crawler-type wire feeding mechanism provided by the utility model has a large contact area between the welding wire and the crawler, the surface of the welding wire is not easily deformed, and can have good contact with the conductive nozzle, ensuring stable wire feeding.
[0014] 2. The outer surface of the track shoe is equipped with inserts with a hardness lower than that of the welding wire, which will produce a "wrapping" effect on the welding wire. The contact area of the welding wire is larger than before. During the welding process, it can improve the welding efficiency and reduce abnormal downtime. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0020] like Figure 1 and Figure 2 As shown, a crawler-type wire feeding mechanism comprises two crawler systems 1 arranged vertically. The outer surfaces of one side of the two crawler systems 1 are arranged parallel and facing each other in the longitudinal direction, forming a gap channel 4 for passing the welding wire 3 therebetween. A driver 2 drives the two crawler systems 1 to rotate at the same speed, introducing the welding wire 3 from one end of the gap channel 4. As the crawler systems rotate, the welding wire 3 is transported from one end to the other, and then passes through the gap channel 4. The end of the welding wire 3 is connected to the conductive tip of the welding gun 5, where it is heated by an electric arc and melted for welding. Using a crawler-type wire feeding mechanism for wire feeding, the contact area between the welding wire 3 and the crawler systems is large, the surface of the welding wire 3 is not easily deformed, and it maintains good contact with the conductive tip, making the welding process smoother.
[0021] like Figure 1 As shown, the crawler system 1 is composed of a driving wheel 11, a driven wheel 12 and a crawler assembly 13 looped on the driving wheel 11 and the driven wheel 12. The crawler assembly 13 includes a chain 131 and a track shoe 132. The chain 131 is hinged by a plurality of chain links 131a in sequence, and the track shoe 132 is fixed to the outer side of each chain link 131a. Figure 4 As shown, the outer surface of the track shoe 132 is also equipped with an insert 133. The hardness of the insert 133 is lower than that of the welding wire 3, which can produce a "wrapping" effect on the welding wire 3. The contact area with the welding wire 3 is larger than before. During the welding process, the welding efficiency can be further improved and abnormal downtime can be reduced.
[0022] In this embodiment, the driving wheel 11 and the driven wheel 12 are both sprockets, and the chain 131 is mounted on the driving wheel 11 and the driven wheel 12. Figure 2 As shown, the shafts of the driving wheels 11 and the driven wheels 12 of the two sets of crawler systems 1 are mounted on the bracket 6 and can be adjusted along the length direction of the bracket 6 to accommodate welding wires 3 of different sizes. Figure 3 As shown, the driver 2 is a motor, and the output shaft of the motor is connected to the driving wheel 11. The motor drives the driving wheel 11 to rotate and drives the chain 131 to rotate, so as to continuously transport the welding wire 3.
[0023] 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.
