Description

Technical Field

[0001] The present application belongs to the field of welding wire straightening, and more specifically, relates to a welding wire straightening device. Background Art

[0002] Automated pipeline welding mainly includes robotic welding and pipeline trolley welding. To improve welding quality and reduce manual intervention, arc tracking is usually required during the welding process to correct the welding trajectory.

[0003] In related technologies, arc tracking primarily adjusts the wire's left-right direction by collecting the current flowing through the wire on both sides of the groove, and then adjusts the arc's height by calculating the average current. However, arc tracking accuracy is closely related to wire straightening. When welding with a curved wire, while arc tracking can align the wire tip with the center of the groove, the arc can deviate from the center of the weld bead as the wire bends, making weld quality unreliable. Therefore, a wire straightening device is required to straighten the wire before welding.

[0004] The existing wire straightening device is usually fixedly connected to the welding equipment, and the welding wire is straightened after passing through. Due to its large size, it occupies a large space after being connected to the welding equipment. When a problem occurs, it is inconvenient to install and replace it. Utility Model Content

[0035] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0036] Reference Figure 1-4 The present application discloses a welding wire straightening device including a mounting frame body 1, a welding wire straightening mechanism 2 and two threaded mounting parts 3. The mounting frame body 1 is made of stainless steel. The welding wire straightening mechanism 2 is installed on the mounting frame body 1. The two threaded mounting parts 3 are respectively arranged on both sides of the mounting frame body 1 and are detachably connected to the mounting frame body 1. The mounting frame body 1 is installed and removed through the threaded mounting parts 3. The welding wire straightening device adopts a split design. Specifically, the mounting frame body 1 can be installed on the welding equipment through the two threaded mounting parts 3 or any one of the threaded mounting parts 3. The welding wire can be straightened through the welding wire straightening mechanism 2, which makes the welding equipment more accurate during welding, stable and reliable in operation, and can greatly improve the arc tracking accuracy and the reliability of automated welding.

[0037] In this embodiment, the length of the mounting frame body 1 is 50mm-60mm, which is small in size and can save installation controls. It is suitable for wire feeders in narrow spaces. Furthermore, a groove 11 is provided on one side of the mounting frame body 1, and the welding wire straightening mechanism 2 is arranged in the groove 11. Through holes 12 connected to the groove 11 are provided on both sides of the mounting frame body 1. During actual use, the welding wire passes through a through hole 12 during the transportation process and is straightened by the welding wire straightening mechanism 2 and then passes through another through hole 12 to complete the welding wire straightening. The welding wire straightening mechanism 2 is located in the groove 11, and the mounting frame body 1 can play a certain protective role on the welding wire straightening mechanism 2 to avoid damage to the welding wire straightening mechanism 2, and at the same time make the structure of the welding wire straightening device more compact and suitable for narrow spaces.

[0038] Furthermore, the through holes 12 on both sides of the mounting frame body 1 are threaded holes, and the through holes 12 are threadedly connected and adapted to the threaded mounting parts 3. A through hole coaxially arranged with the through hole 12 is provided on the threaded mounting part 3. One end of the threaded mounting part 3 is connected to the through hole 12, and the other end is connected to the welding equipment. The welding wire can pass through the through hole on the threaded mounting part 3 into the groove 11, and then be straightened by the welding wire straightening mechanism 2. In this embodiment, the threaded mounting part 3 adopts the quick-insert threaded joint commonly used in this field, and the connection is simple and convenient.

[0039] In this embodiment, the welding wire straightening mechanism 2 includes two positioning wheels 21 and one movable wheel 22. The two positioning wheels 21 and the movable wheel 22 are arranged in a triangular structure. The positioning wheel 21 is rotatably connected to the mounting frame body 1 through a connecting shaft. The outer peripheral walls of the positioning wheel 21 and the movable wheel 22 are both provided with an annular groove 211. The two positioning wheels 21 and the movable wheel 22 are both arranged in the groove 11 and the rotation axes are parallel to each other. A channel for the welding wire to pass through is left between the positioning wheel 21 and the movable wheel 22. After the welding wire enters the groove 11, it passes through the channel. During the transportation process, the welding wire passes between the positioning wheel 21 and the movable wheel 22, which can automatically complete the straightening of the welding wire, and the welding wire is located in the annular groove 211 on the positioning wheel 21 and the movable wheel 22, thereby improving the transportation stability of the welding wire.

[0040] In order to be suitable for straightening welding wires of different diameters, the welding wire straightening mechanism 2 also includes a driving component 23. The two positioning wheels 21 are arranged along the opening direction of the through hole 12 and are fixed in position. In this embodiment, the two positioning wheels 21 are arranged left and right in the horizontal direction. When the welding wire is transported, it fits into the outer walls of the two positioning wheels 21. The movable wheel 22 is movably arranged in the vertical direction to approach or move away from the two positioning wheels 21. The movable wheel 22 is driven to move by the driving component 23. The driving component 23 drives the movable wheel 22 to move to adjust the distance between the positioning wheel 21 and the movable wheel 22, so that it can be suitable for straightening welding wires of different specifications.

[0041] Specifically, the driving assembly 23 includes a slider 231 and a screw 232. The slider 231 is slidably connected to the mounting frame body 1. The mounting frame body 1 is provided with a slide groove 13 that is slidably adapted to the slider 231, so as to improve the sliding stability of the slider 231. The movable wheel 22 is rotatably connected to the slider 231 through a connecting shaft, and the screw 232 is rotatably connected to the mounting frame body 1. After the screw 232 extends into the slide groove 13, it passes through the slider 231 and is threadedly adapted to the slider 231. Rotating the screw 232 can drive the sliding movement, thereby completing the position adjustment of the movable wheel 22. The adjustment is convenient and fast. A scale mark 14 is provided along the moving direction of the movable wheel 22 on the inner wall of the groove 11. A pointer 233 for indicating the scale mark 14 is fixedly connected to the slider 231, so that the distance moved by the movable wheel 22 can be intuitively seen, so that it can be adjusted and reset after use.
