Description

Technical Field

[0001] This application belongs to the field of welding, and more specifically, relates to a highly convenient and stable wire feeding system. Background Technology

[0002] Since its inception, the marine engineering industry has witnessed the leapfrog development of subsea pipelines from shallow waters to medium-deep waters, deep waters, and ultra-deep waters. Pipe-laying vessels are like "factories" for land-based operations, consisting of multiple work stations such as pipeline end processing stations, assembly and welding stations, inspection stations, and joint coating stations. Among these, assembly and welding is the key process after the pipes are joined and laid into the seabed.

[0003] Offshore pipelaying vessels are expensive to build, with daily operating costs typically exceeding one million, making equipment stability and ease of use crucial. For assembly welding stations, welding equipment must be quickly installed in the confined space of the vessel before pipelaying operations. If the original wire feeder matched with the welding machine is used, a wire straightener usually needs to be installed and adjusted separately, and a shielding gas supply from an external gas source needs to be connected and a flow regulating device installed, undoubtedly increasing installation time and costs. In particular, placing an independent wire spool and wire feeder on the welding machine mounting platform greatly affects operational convenience, and improper placement of the wire spool can also significantly affect wire feeding stability, leading to unstable welding. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a highly convenient and stable wire feeding system, aiming to solve the problems of low installation efficiency, large operating space occupation, and poor wire feeding stability of existing wire feeding systems during pipelaying operations.

[0005] This application provides a highly convenient and stable wire feeding system, specifically including a wire feeding box body, a wire spool, a wire spool frame, a wire straightening device, and a wire feeder. The wire spool frame, the wire straightening device, and the wire feeder are sequentially installed inside the wire feeding box body along the wire feeding direction. The wire spool is detachably installed on the wire spool frame, and both sides of the wire spool are provided with limiting devices. The wire on the wire spool passes through the wire straightening device and is then fed out by the wire feeder.

[0006] Compared with the prior art, the above-described technical solution conceived in this application greatly increases the installation efficiency and convenience of the wire feeding system by highly integrating the wire spool, wire spool holder, wire straightening device, and wire feeder into the main body of the wire feeding box. At the same time, the wire feeding system does not occupy the welder's operating space, and the straightened wire will not be touched by the welder during operation, affecting the wire feeding stability. This achieves the beneficial effects of improving the stability of wire feeding and the convenience of wire feeding system installation. In addition, after the wire spool is installed on the wire spool holder, both sides of the wire spool can be limited, thereby making the rotation of the wire spool more stable during wire feeding and further improving the wire feeding effect.

[0007] As a further preferred embodiment, the welding wire spool frame includes a mounting plate, a rotating roller, and a threaded cover. The mounting plate is fixedly connected to the inner wall of the wire feeding box body. The rotating roller is rotatably connected to the mounting plate with its rotation axis perpendicular to the mounting plate. The threaded cover is threadedly connected to the end of the rotating roller away from the mounting plate. The welding wire spool is sleeved on the rotating roller with its two ends abutting against the mounting plate and the threaded cover, respectively.

[0008] By adopting the above technical solution, after the welding wire spool is sleeved on the rotating roller, the threaded cover is rotated to make the other side of the welding wire spool abut against the mounting plate, thereby achieving the limitation of both sides of the welding wire spool. The structure is simple and the operation is convenient.

[0009] As a further preferred embodiment, the outer wall of the rotating roller is provided with a positioning protrusion, and the welding wire spool is provided with a positioning groove that fits into the positioning protrusion.

[0010] By adopting the above technical solution, the welding wire spool is relatively stable with the rotating roller after being sleeved on the rotating roller, which further improves the stability of the welding wire spool.

The welding wire passes through the two straightening mechanisms in sequence, and the force direction of the welding wire in the two straightening mechanisms is different.

[0013] As a further preferred embodiment, the straightening mechanism includes a mounting base and a straightening component. A groove is provided on one side of the mounting base, and the straightening component is disposed in the groove. Through holes are provided on both sides of the mounting base. The welding wire passes through one through hole, is straightened by the straightening component, and then exits through the other through hole.

[0014] By adopting the above technical solution, the straightening component is located in the groove, and the mounting base can provide a certain degree of protection for the straightening component, while also saving more space.

[0015] As a further preferred embodiment, the straightening assembly includes a positioning wheel and a movable wheel, both of which are disposed in a groove and have their rotation axes parallel to each other, with a welding wire channel between the positioning wheel and the movable wheel.

[0016] By adopting the above technical solution, the welding wire passes between the positioning wheel and the movable wheel during the conveying process, which can automatically complete the straightening of the welding wire. The structure is simple and the straightening effect is good.

[0017] As a further preferred embodiment, the movable wheel is movably positioned to move closer to or further away from the positioning wheel, and the straightening assembly further includes a drive element for driving the movable wheel to move.

[0018] By adopting the above technical solution, the driving component drives the movable wheel to move in order to adjust the distance between the positioning wheel and the movable wheel, thereby making it suitable for straightening welding wires of different specifications.

[0019] As a further preferred embodiment, the driving component includes a slider and a screw, the mounting base has a groove, the slider is slidably connected in the groove, the movable wheel is disposed on the slider, the screw is rotatably connected to the mounting frame body, and the screw passes through the slider and is threadedly connected to the slider.

[0020] By adopting the above technical solution, the rotating screw can drive the sliding wheel to move within the groove, thereby completing the position adjustment of the movable wheel, which is convenient and quick.

[0021] As a further preferred embodiment, the system also includes a gas supply device for providing welding shielding gas.

[0022] By adopting the above technical solution, the gas supply device can provide protective gas for the welding process, making the welding process safer.

[0023] As a further preferred embodiment, the gas supply device includes an inlet pipe, an outlet pipe, and a gas flow meter. The gas flow meter is fixedly installed between the inlet pipe and the outlet pipe. The inlet pipe and the outlet pipe are connected through the gas flow meter, and the other end of the inlet pipe is connected to an external gas source.

[0024] By adopting the above technical solution, the gas flow meter can monitor the airflow in the inlet and outlet pipes, ensuring that the gas supply device provides a stable flow of protective gas.

[0025] As a further preferred embodiment, the wire feeding box body is hung on the mounting frame.

[0026] By adopting the above technical solution, the main body of the wire feeding box is suspended and installed, which increases the convenience of mobilizing and demobilizing equipment at the construction site.

[0027] In summary, compared with the prior art, the technical solutions conceived in this application have the following main technical advantages:

[0028] 1. In this application, the wire spool, wire spool holder, wire straightening device, and wire feeder are integrated into the wire feeding box body with a high degree of integration. This allows for direct installation by transferring the wire feeding box body, greatly increasing the installation efficiency and convenience of the wire feeding system. At the same time, this wire feeding system does not occupy the welder's operating space, and the straightened wire will not be touched by the welder during operation, thus affecting the wire feeding stability. This achieves the beneficial effects of improving the stability of wire feeding and the ease of installation of the wire feeding system.

[0029] 2. In this application, by installing the wire spool with the welding wire wound on it on the wire spool frame, and limiting the two sides of the wire spool by the mounting plate and the threaded cap respectively, the rotation of the wire spool is more stable when the welding wire is fed. This can achieve the beneficial effect of improving the stability and speed uniformity of the wire feeding. At the same time, the wire is straightened by the wire straightening device before feeding, which further improves the wire feeding effect.

[0030] 3. The welding wire straightening device in this application includes two straightening mechanisms, which can improve the straightening effect of the welding wire, adapt to welding wires with different bending angles, and thus further improve the wire feeding stability and speed uniformity.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0039] Reference Figure 1-4 This application discloses a highly convenient and stable wire feeding system, comprising a wire feeding box body 1, a welding wire spool 2, a welding wire spool frame 3, a welding wire straightening device 4, and a wire feeder 5, as well as a gas supply device 6 and a mounting frame 7. The wire feeding box body 1 is detachably hung on the mounting frame 7 via a suspension structure. Specifically, a hook hole is provided on the top of the wire feeding box body 1, and a hook is fixedly connected to the mounting frame 7. The hook is passed through the hook hole on the wire feeding box body 1, allowing the wire feeding box body 1 to be hung on the mounting frame 7, increasing the convenience of equipment mobilization and demobilization at the construction site.

[0040] In this embodiment, the wire spool holder 3, the wire straightening device 4, and the wire feeder 5 are all installed inside the wire feeding box body 1 and arranged sequentially from top to bottom along the wire feeding direction. The wire feeder 5 is vertically fixed to the bottom plate of the wire feeding box body 1, and the wire feeder 5's cable interface extends to the outside of the wire feeding box body 1. The wire spool 2 is detachably installed on the wire spool holder 3, and the wire spool 2 is provided with limiters on both sides after installation. Specifically, the wire spool holder 3 includes a mounting plate 31, a rotating roller 32, and a threaded cover 33. The mounting plate 31 is fixedly connected to the inner wall of the wire feeding box body 1 by screws. The rotating roller 32 is rotatably connected to the mounting plate 31, and its rotation axis is perpendicular to the mounting plate 31. The threaded cover 33 is connected to the rotating roller. The end of the welding wire spool 2 away from the mounting plate 31 is threaded and adapted. The welding wire spool 2 is sleeved on the rotating roller 32 and its two ends abut against the mounting plate 31 and the threaded cover 33 respectively. After the welding wire spool 2 is sleeved on the rotating roller 32, the threaded cover 33 is rotated so that the other side of the welding wire spool 2 abuts against the mounting plate 31, thereby limiting the two sides of the welding wire spool 2. At the same time, the outer wall of the rotating roller 32 is provided with a positioning protrusion 321. The welding wire spool 2 is provided with a positioning groove that fits into the positioning protrusion 321. When the welding wire spool 2 is sleeved on the rotating roller 32, the positioning protrusion 321 is located in the positioning groove, which improves the stability of the welding wire spool 2. The welding wire on the welding wire spool 2 is straightened by the welding wire straightening device 4 and then fed out by the wire feeder 5.

[0041] To straighten the welding wire on the welding wire spool 2, the welding wire straightening device 4 includes two straightening mechanisms. Both mechanisms are installed inside the wire feeding box body 1 and are located on the same straight line. The welding wire passes through the two straightening mechanisms sequentially, and the force directions of the welding wire in the two straightening mechanisms are different. The welding wire is straightened sequentially through the two straightening mechanisms, improving the straightening effect and accommodating welding wires with different bending angles. The welding wire straightening device 4 also includes three threaded mounting parts. The two straightening mechanisms are connected as a whole by a threaded mounting part. The other ends of both straightening mechanisms are connected by threads... The threaded mounting component is installed inside the wire feeding box body 1; the straightening mechanism includes a mounting base 41 and a straightening assembly 42. A groove is provided on one side of the mounting base 41, and the straightening assembly 42 is disposed within the groove. Through holes are provided on both sides of the mounting base 41. The welding wire passes through one through hole, is straightened by the straightening assembly 42, and then exits through the other through hole. The threaded mounting component is installed at the through hole. The middle part of the threaded mounting component is hollow, allowing the welding wire to pass through the threaded mounting component and enter the groove on the mounting base 41. The straightening assembly 42 includes a positioning wheel 421, a movable wheel 422, and a driving component 423. Both the positioning wheel 421 and the movable wheel 422 are located in the groove and their rotation axes are parallel to each other. A welding wire channel is located between the positioning wheel 421 and the movable wheel 422. In this embodiment, three positioning wheels 421 and two movable wheels 422 are provided, with the two movable wheels 422 corresponding to the two gaps between the three positioning wheels 421. The movable wheels 422 are driven to move by the driving component 423. The movable wheels 422 are movably positioned to move closer to or further away from the positioning wheels 421. In this embodiment, the driving component 423 includes a slider 4231 and a screw 4232. A groove 4 is provided on the mounting base 41. 11. The slider 4231 is slidably connected in the groove 411. The movable wheel 422 is set on the slider 4231. The screw 4232 is rotatably connected to the mounting frame body. The screw 4232 passes through the slider 4231 and is threadedly connected to the slider 4231. During the conveying process, the welding wire passes between the positioning wheel 421 and the movable wheel 422, which can automatically complete the straightening of the welding wire. The movable wheel 422 is driven to move by the driving component 423 to adjust the distance between the positioning wheel 421 and the movable wheel 422, so that it can be used to straighten welding wires of different specifications.

[0042] Furthermore, this application provides welding shielding gas for the welding process through a gas supply device 6. The gas supply device 6 includes an inlet pipe 61, an outlet pipe 62, and a gas flow meter 63. The gas flow meter 63 is fixedly installed between the inlet pipe 61 and the outlet pipe 62 and is located outside the wire feed box body 1. The inlet pipe 61 and the outlet pipe 62 are connected through the gas flow meter 63, and the other end of the inlet pipe 61 is connected to an external gas source. An air pump can be installed on the outlet pipe 62 to discharge the shielding gas.

[0043] The outer side of the wire feeding box body 1 is provided with buttons for controlling the forward and reverse wire feeding of the wire feeder 5 and buttons for controlling the opening and closing of the gas supply device 6.
