Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to an electric welding machine with automatic wire feeding. Background Art

[0002] In the field of welding technology, electric welders are essential equipment, and their performance and efficiency directly impact welding quality and production efficiency. While traditional manual wire-feeding welders meet welding needs to a certain extent, they suffer from issues such as unstable wire feeding speed, low wire feeding accuracy, and high labor intensity. These issues are particularly prominent in large-scale, high-efficiency welding production. To overcome these shortcomings, automatic wire-feeding welders have emerged. Automatic wire-feeding welders utilize mechanical or electronic devices to automatically feed the welding wire, significantly improving the automation level and production efficiency of welding. However, with the continuous advancement of welding technology and the expansion of its application areas, the performance requirements for automatic wire-feeding welders are also increasing. Currently, most automatic wire-feeding welders on the market use a motor-driven wire feeding mechanism, adjusting the wire feeding speed and direction by controlling the motor's speed and direction. However, this wire-feeding method still presents several challenges in practical applications, such as the tendency for the wire to bend and tangle during feeding, difficulty in ensuring wire feeding accuracy, and the susceptibility of the wire-feeding mechanism to malfunction under various welding conditions.

[0003] The reference patent name is an automatic wire feeder for an electric welding machine with pre-straightened wire (publication number CN218903934U), which includes a frame, a wire reel is rotatably mounted on the frame through a first connecting seat, a mounting seat is fixedly mounted on the frame, a motor is fixedly mounted on one end of the mounting seat, a wire feeding wheel is fixedly mounted on the output shaft of the motor, and a plurality of wire-carrying bottom wheels are rotatably mounted at a linear and equidistant interval on a side position of the mounting seat close to the wire feeding wheel, an electric push rod is fixedly mounted on the frame through a first top frame, a lifting seat is fixedly mounted on the telescopic end of the electric push rod, a wire straightening pressure wheel is rotatably mounted on the lifting seat, a second top frame is fixedly connected to the top side of the frame, and a square rod is movably penetrated through the surface of the second top frame. The utility model can prevent the welding wire from easily generating large stress due to its own vibration during transportation, and avoid the welding wire that has been pre-straightened and straightened during transportation, which is beneficial to ensure continuous and stable transportation of the welding wire.

[0004] Although the above patent solves the problem of the welding wire being easily bent during the wire feeding process of the wire feeder, as welding continues, the welding wire is continuously consumed, and the user cannot know the amount of internal welding wire from the outside of the wire feeder. In actual application, personnel need to check it by themselves, which is prone to omissions. For this reason, the utility model provides an electric welding machine with automatic wire feeding. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides an electric welding machine with automatic wire feeding, which solves the problem that as the electric welding machine continues to weld, the welding wire is continuously consumed, and the user cannot know the internal welding wire inventory from the outside of the wire feeder. In actual application, personnel need to check it by themselves, which is prone to omissions.

[0014] Beneficial effects

[0015] The utility model provides an electric welding machine with automatic wire feeding. Compared with the prior art, it has the following beneficial effects:

When the amount of welding wire is sufficient, the T-shaped conductive piece is outside the first and second power-connecting pieces, the circuit is not connected, and the buzzer does not work. When the welding wire gradually decreases, the wire pressing block moves inward and finally touches the T-shaped conductive piece. The power supply forms a circuit through the second power-connecting piece, the T-shaped conductive piece, and the first power-connecting piece to supply power to the buzzer. The buzzer then sounds to remind the operator that the welding wire is about to run out and needs to be replaced or added in time.

[0017] (2) The automatic wire-feeding electric welding machine is designed with a wire pressing assembly, in which the horizontal block is connected to the vertical block by a movable connecting rod, and a spring is provided between the vertical blocks to provide elastic force, so that the wire pressing block can be pressed against the welding wire for squeezing, ensuring that the wire pressing block can be displaced as the welding wire is reduced; in addition, the guide structure provided on one side of the horizontal block ensures that during the process of squeezing the welding wire, the horizontal block and the wire pressing block can move smoothly and will not deviate from the predetermined path.
