Abstract
Description
Technical Field
[0001] This utility model relates to the field of flange welding technology, and in particular to a welding device for flange production. Background Technology
[0002] Flange welding is a crucial process for pipeline connections, with common types including slip-on welding, butt welding, and socket welding. Slip-on welding is used for low-pressure, small-diameter pipes, butt welding is suitable for harsh environments such as high pressure and high temperature, and socket welding is used for small-diameter pipes. The process includes pre-weld preparation, beveling, assembly and positioning, welding operation, and weld inspection. During welding, it is important to control deformation, prevent defects, pay attention to the environmental conditions, and perform proper post-weld treatment to ensure weld quality and guarantee the safe and stable operation of the pipeline system.
[0003] When welding flanges, welders need to perform welding operations at a certain angle at the weld point. During the welding process, the flange structure also needs to be rotated as the welding progresses to avoid affecting the welding quality due to the welder's inability to move the handheld welding equipment smoothly.
[0004] Based on this, a welding device for flange production is proposed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-3 This utility model provides a technical solution:
[0023] A welding device for flange production includes a base 1, a connecting block 2 connected to the upper end of the base 1, a hinge frame 3 connected to the connecting block 2, a placement plate 5 rotatably connected to the hinge frame 3, a clamping piece 9 connected to the placement plate 5, and an adjustment mechanism for adjusting the deflection angle of the placement plate 5 connected to the connecting block 2.
[0024] Specifically, such as Figure 1 As shown, a fixing block 7 is connected to the placement plate 5, and a cylinder 8 is connected to one side of the fixing block 7. A clamping plate 9 is fixedly connected to the telescopic end of the cylinder 8. The clamping plate 9 can be used to fix the flange structure and improve the firmness of the flange structure connection during welding.
[0025] Specifically, such as Figure 3 As shown, a limiting frame 14 is connected to the hinge frame 3, and a rotating column 13 is rotatably connected to the limiting frame 14. The rotating column 13 is fixedly connected to the lower end of the placement plate 5. The rotating column 13 and the limiting frame 14 cooperate with each other, so that the flange structure can be rotated at the same time during the welding process, thereby changing the welding position without the need for the welder to move, which improves the convenience of welding.
[0026] Specifically, such as Figure 2 and Figure 3 As shown, a rotating shaft 12 is connected to the hinge frame 3, and the limiting frame 14 is rotatably connected to the rotating shaft 12. By setting the rotating shaft 12 structure, the tilt angle of the flange can be easily adjusted.
[0027] Specifically, such as Figure 2 and Figure 3 As shown, the adjustment mechanism includes an arc-shaped rail 4, which is fixedly connected to the connecting block 2. The arc-shaped rail 4 has a slot 10. The lower end of the limit frame 14 is connected to a cylinder 11, and one end of the cylinder 11 is connected to a locking block 16. The locking block 16 abuts against the arc-shaped rail 4 to fix the cleaning angle of the placement tray 5. The structure is simple and the fixing operation can be completed quickly, which greatly improves the flange welding efficiency.
[0028] Specifically, such as Figure 2 and Figure 3 As shown, one end of cylinder 2 11 is connected to a limit rod 15, and a locking block 16 is fixedly connected to the limit rod 15. The limit rod 15 is slidably arranged between the arc-shaped rails 4. The structure of the limit rod 15 serves to limit the structure of cylinder 2 11 and prevent the structure of the placement plate 5 from shifting. A handle 6 is connected to the outside of the placement plate 5. The handle 6 is mainly designed to facilitate the operation of the welding personnel.
[0029] In summary, the welding device for flange production provided in this embodiment allows the flange to be placed in the center of the placement plate 5 when flange production welding is required. Then, two cylinders 8 are operated in conjunction with the clamping plate 9 to clamp the flange structure. This clamping structure is also suitable for welding clamping between the flange and other structures.
[0030] The welder can then adjust the tilt angle of the placement plate 5 according to the welding technique, and then control the extension of the cylinder 11 so that the limit rod 15 drives the locking block 16 to abut against the arc-shaped rail 4. The arc-shaped rail 4 is marked with corresponding tilt angle marks to indicate the tilt angle during flange welding. The arc-shaped rail 4 is also marked with a distinctive groove 10 structure. The number of grooves 10 can be adjusted according to the actual welding requirements. The simplest number of grooves 10 is two, corresponding to 0° and 90° of flange tilt, respectively.
[0031] After fixing the flange tilt angle, the welder can hold the welding tool in one hand and the handle 6 in the other, and rotate the flange structure as welding progresses, thereby completing the flange production welding.
[0032] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
