Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a balanced wire pressing structure for a wire feeder. Background Technology

[0002] Wire feeding is a crucial step in the welding process. In manual TIG welding, the wire feeding method often involves the welder twisting the welding wire with their fingers. This is very inconvenient for the welder, resulting in poor accuracy, inconsistency, and instability, leading to low welding efficiency and inconsistent weld formation. Furthermore, the welder has limited wire length to hold, requiring frequent handling during prolonged welding, further reducing efficiency. Also, a small section of wire remains unusable after each welding operation, causing waste. Therefore, wire feeders are often used in conjunction with a welding torch for wire feeding.

[0003] Chinese patent application number 202420123780.8 discloses a handheld electric wire feeder for argon arc welding, comprising a housing, a groove formed on the outer wall of the housing, a fixed rod movably sleeved in the inner cavity of the groove, a fixed cylinder fixedly fitted on the inner wall of the groove, a movable rod movably sleeved in the inner cavity of the fixed cylinder, a drive spring fixedly fitted on the outer wall of the movable rod, a bearing wheel rotatably connected to the outer wall of the fixed rod, a control switch fixedly fitted on the outer wall of the housing, a speed regulator installed on the outer wall of the housing, and a rotating rod rotatably connected to the inner wall of the housing. A drive wheel is mounted on the outer wall, and a driven gear is fixedly mounted on the outer wall of the rotating rod. A drive motor is fixedly mounted in the inner cavity of the housing, and a drive gear is fixedly mounted on the outer wall of the drive motor. A welding wire is mounted on the outer wall of the drive wheel. Through the support wheel and drive wheel set in the inner cavity of the housing, the drive wheel is rotated under the drive of the drive gear. During the rotation of the drive wheel, the welding wire can be moved on the outer wall of the support wheel and the drive wheel, thereby better propulsing the welding wire and making the welding wire move forward stably under the action of the drive wheel, which is more conducive to the control of the welding wire.

[0004] However, the handheld electric wire feeder for argon arc welding cannot actively apply pressure to the pressure roller during use, and the staggered drive wheel and bearing wheel have a poor straightening effect on the metal wire, making it difficult to ensure the straightness of the metal wire when it is fed out, thus reducing the practicality of the handheld electric wire feeder for argon arc welding. To address this, we propose a balanced wire pressing structure for the wire feeder. Utility Model Content

This allows for easy adjustment of the pressure of the pressure rollers 16 according to different needs, improving the practicality of the balanced wire pressing structure of the wire feeder. One end of the telescopic spring 22 is fixedly connected to the bottom of the fourth slide rod 21, and the other end of the telescopic spring 22 is fixedly connected to the outside of the pressure sensor 23.

[0023] An electric telescopic rod 17 is fixedly installed inside the housing 1. The output end of the electric telescopic rod 17 is fixedly connected to the mounting plate 13.

This, in turn, moves the two sets of second rotating rollers 15 and pressure rollers 16, adjusting their positions and adjusting the pressure rollers 16 to apply pressure to the material. When the mounting plate 13 moves, it causes the third slide rod 20 and the fourth slide rod 21 to slide within the third slide groove 18 and the fourth slide groove 19, thus adjusting the extension and retraction... Spring 22 compresses the material, thereby detecting the pressure through pressure sensor 23. The detected data is then transmitted to the control device for easy operation by the staff.
