Description

Technical Field

[0001] This utility model relates to the field of submerged arc welding technology, specifically to a dual-wire submerged arc welding head structure. Background Technology

[0002] Submerged arc welding is a high-efficiency automated welding process commonly used for welding thick plate structural components. It has advantages such as fast welding speed, beautiful weld formation, and stable welding quality, and is widely used in bridge, pressure vessel, shipbuilding and large structural component production. Existing single-wire submerged arc welding head structures usually complete the deposition operation with a single welding wire. Although it can meet general welding needs, when faced with thick plate and high-strength welding tasks, the deposition efficiency is low, the weld filling speed is insufficient, and it is difficult to meet the requirements of high efficiency and high stability welding.

[0003] To improve production efficiency, the industry is gradually promoting "twin-wire submerged arc welding" technology, which involves simultaneously feeding two welding wires into the weld zone to achieve higher deposition rates and stronger forming capabilities. However, existing twin-wire welding head structures still have several problems in application. First, the welding wires are prone to tangling during the twin-wire feeding process, especially when the wire output path is long or the angle changes significantly, often leading to wire friction and jamming, affecting welding continuity and stability. Second, the installation position and posture requirements vary in different welding scenarios, and existing head structures generally have poor adjustability, making it difficult to flexibly adjust according to factors such as workspace and equipment layout. Third, some welding head structures are highly fixed in their connection and support methods, often requiring additional modifications or fixed brackets when changing the application scenario or installing on different support equipment, which is not conducive to universal application.

[0004] In addition, if the welding wire is subjected to uneven force or has attached impurities during the output process, it is easy to cause the welding wire to deviate and be obstructed, thereby affecting the stability of the arc and the quality of the weld. Although the existing device has partially introduced a guide wheel structure, its anti-winding and line-aligning effects are limited, and it is difficult to effectively improve the guiding accuracy and anti-winding performance when two wires are output at the same time.

[0005] In summary, existing dual-wire submerged arc welding head structures generally suffer from problems such as high risk of wire entanglement, limited adjustment range, poor adaptability, and simple protective structure. This application proposes a dual-wire submerged arc welding head structure to solve these problems, thereby improving the stability of welding operations and overall operational efficiency.

Therefore, they should not be construed as limitations on this utility model.

[0041] This application proposes a dual-wire submerged arc welding head structure, as detailed below:

[0042] For reference Figure 1-3 This application mainly consists of a welding torch 1, a welding material bin 2, a crossbar 3, a connecting shaft 4, a support 5, an anti-tangle component 6, a connecting component 7, and a wire feeding roller 8, which work together to form a cohesive whole. Through the coordination of these components, flexible installation and adjustment can be achieved under various usage conditions. Furthermore, during double-wire embedding operations, it effectively prevents welding wire tangling, avoiding any impact on welding stability and operational efficiency.

[0043] For reference Figure 1-3 The welding torch 1 is used to control the welding energy and the direction of the welding wire transmission; the welding material container 2 is located on one side of the welding torch 1, and its output end is connected to the outlet end of the welding torch 1. The two structures are common existing technology connection methods, and this application will not elaborate further.

[0044] For reference Figure 1-3 One end of the crossbar 3 is fitted onto the outer surface of the welding torch 1 to provide structural support for subsequent components. One end of the connecting shaft 4 is fixedly connected to the crossbar 3, and the other end is connected to the solder bin 2, thus ensuring that both the solder bin 2 and the welding torch 1 are stably installed. A mounting shaft 31 is provided on the side of the crossbar 3 away from the welding torch 1, which is used to connect to an external electrical control box.

[0045] For reference Figure 1-3 The support member 5 is located on the side of the welding torch 1 away from the solder bin 2 and is mounted on the crossbar 3; the anti-tangling member 6 is mounted on the support member 5. Specifically, the support member 5 includes an adjusting shaft 51, a telescopic rod 52 and a connecting plate 53. The adjusting shaft 51 is detachably fixed to the crossbar 3 by bolts, the telescopic rod 52 is fixedly connected to the adjusting shaft 51, and the connecting plate 53 is located at the end of the telescopic rod 52 away from the adjusting shaft 51.

[0046] The detachable design of the adjusting shaft 51 enables the support component 5 to have good adjustability. When the structure needs to be changed or replaced, it can be quickly replaced with a more suitable component, thereby improving assembly flexibility. The telescopic rod 52 adopts an existing mature telescopic structure to achieve the height adjustment function, which will not be described in detail here. By adjusting the length of the telescopic rod 52, the connecting plate 53 can be raised and lowered synchronously, thereby changing the installation height of the anti-entanglement component 6. This structure allows the anti-entanglement component 6 to flexibly adjust its height according to different usage scenarios, significantly improving the adaptability and practical range of the device.

[0047] Specifically, the anti-tangling component 6 includes an outer frame 61 and a wire guide shaft 62. The outer frame 61 is detachably mounted on the connecting plate 53. Two symmetrically arranged wire guide shafts 62 form a set, and there are two sets in total. These sets are used to receive the welding wire output from the two sets of wire feeding rollers 8, thereby effectively reducing the tangling of the welding wire during the output process and improving the smoothness and stability of wire feeding. It should be noted that there are two sets of wire feeding rollers 8, symmetrically arranged on the crossbar 3, for outputting the welding wire.

[0048] Furthermore, the guide shaft 62 includes a connecting rod 621, a rotating shaft 622, and an arc-shaped frame 623. The connecting rod 621 is fixedly disposed inside the outer frame 61, and the rotating shaft 622 is rotatably disposed at both ends of the connecting rod 621. One side of the arc-shaped frame 623 is fixedly connected to the connecting rod 621. Another guide shaft 62 in the set is arranged symmetrically with it, and the arc-shaped frames 623 of the two form a guide path for the welding wire to pass through. When the welding wire undergoes slight deformation or is covered with impurities during operation, the welding wire will come into frictional contact with one of the rotating shafts 622. The rotating shaft 622 rotates under the action of force, and the friction action removes impurities from the surface of the welding wire or performs minor correction of deformed parts, thereby maintaining the stability and smoothness of the welding wire output path.

[0049] For reference Figure 1-3 The connector 7 is adjustablely mounted on the crossbar 3, with its two ends connected to an external support mechanism. Further, the connector 7 includes a cross-shaped adjusting shaft 71, a snap-fit ​​frame 72, and an access shaft 73. The cross-shaped adjusting shaft 71 is sleeved on the crossbar 3 and fixed with bolts, the snap-fit ​​frame 72 is disposed on one side of the surface of the cross-shaped adjusting shaft 71, and the access shaft 73 is detachably mounted on both ends of the cross-shaped adjusting shaft 71 by bolts.

[0050] The cross-shaped adjusting shaft 71 can be adjusted in its installation position on the crossbar 3 according to actual needs, and both ends are provided with connection ports adapted to the access shaft 73. The size of the cross-shaped adjusting shaft 71 is not specifically limited, as long as one end can be installed with itself and the other end can be connected to the target structure.

[0051] For example, in one embodiment, when the connector 7 needs to be used with the vehicle assembly, one end of the access shaft 73 is adapted to be installed on the trolley structure, and the other end is fixed to the bottom of the cross adjustment shaft 71; in another embodiment, when the device needs to be used in a suspended manner, the access shaft 73 can be set at the top of the cross adjustment shaft 71 so as to be connected to the upper support structure.

[0052] Furthermore, for scenarios where the connector 7 needs to be attached to a crossbeam, a snap-fit ​​frame 72 is provided. Through the cooperation of the snap-fit ​​frame 72 and bolts, the connector 7 can be securely installed at the designated crossbeam position, enabling rapid installation and structural adaptation in multiple scenarios.

[0053] In this invention, the working steps of the device are as follows:

[0054] 1. First, adjust the relative position of the crossbar 3 and the welding gun 1 according to the operation requirements, and fix the welding material tank 2 to one side of the welding gun 1 through the connecting shaft 4 so that the welding gun 1 and the welding material tank 2 form a stable welding assembly; at the same time, confirm that the mounting shaft 31 at one end of the crossbar 3 is reliably connected to the external electrical control box, so as to provide a basis for the subsequent transmission of welding energy and control signals.

[0055] 2. Next, adjust the installation status of the support component 5 according to the working environment and the direction of the welding wire placement. Adjust the installation position of the support component 5 on the crossbar 3 by adjusting the shaft 51, and then adjust the length of the telescopic rod 52 so that the connecting plate 53 and the anti-tangling component 6 installed on it are at a suitable height, thereby ensuring that the welding wire passes smoothly on the running path;

[0056] 3. Then, after the wire feeding rollers 8 are installed, the welding wire output from the two sets of wire feeding rollers 8 is guided to the two sets of straightening shafts 62 in the anti-tangling component 6, so that the welding wire passes through the guide path formed by the arc frame 623; when the welding wire is running, the straightening shaft 62 rotates automatically under force to remove slight impurities on the surface of the welding wire and maintain the straightness of the output, preventing tangling.

[0057] 4. Finally, adjust the connection method of connector 7 according to the specific installation environment. If the device needs to be fixed on the loading vehicle, the access shaft 73 can be installed at the bottom of the cross-adjustment shaft 71 and connected to the trolley structure. If it needs to be suspended, the access shaft 73 can be installed at the top of the cross-adjustment shaft 71 to connect to the upper support structure. If it needs to be hung on the crossbeam, the device can be fixed in the designated position by using the snap-fit ​​frame 72 and bolts. After completing the above steps, dual-wire synchronous output and stable welding operation can be achieved.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
