Description

Technical Field

[0001] This utility model relates to a device for improving the weld roughness of zinc-aluminum-magnesium welded pipes, belonging to the field of zinc-aluminum-magnesium welded pipes. Background Technology

[0002] Zinc reinforcement of the weld seam of zinc-aluminum-magnesium welded pipe is an important measure to ensure its corrosion resistance, because the high temperature during the welding process can damage the original zinc-aluminum-magnesium coating, making the area more susceptible to corrosion.

[0003] During the production of welded pipes, after passing through the high-frequency welding zone, the weld seam produced by welding needs to be smoothed using an external scraper. After smoothing, zinc is sprayed onto the weld seam using a zinc spray gun to achieve the effect of zinc supplementation. However, when measuring the zinc layer thickness of the weld seam of the finished zinc-aluminum-magnesium pipe, it was found that the zinc layer data at the weld seam fluctuated and was unstable. This resulted in the frequent need for manual zinc supplementation in the production of zinc-aluminum-magnesium welded pipes, which was time-consuming, labor-intensive, and ineffective. The main reason was that the surface roughness of the weld seam after smoothing was insufficient, resulting in poor adhesion when spraying zinc and the zinc layer thickness not meeting the requirements.

[0004] To address the aforementioned problems, this application proposes a device for improving the weld roughness of zinc-aluminum-magnesium welded pipes. Utility Model Content

[0005] The present invention aims to overcome existing defects and provides a device for improving the roughness of the weld seam of zinc-aluminum-magnesium welded pipes. This device can effectively improve the roughness of the weld seam of zinc-aluminum-magnesium welded pipes after scraping, and improve the subsequent zinc replenishment effect, thus effectively solving the problems in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An apparatus for improving the weld roughness of zinc-aluminum-magnesium welded pipe includes a zinc-aluminum-magnesium welded pipe with a weld seam formed at the top. A steel brush is provided at the top of the zinc-aluminum-magnesium welded pipe, and a drive motor is provided on one side of the steel brush. The drive motor is mounted on a mounting base, and an output shaft is fixedly connected to the output end of the drive motor. The steel brush is fixedly installed at the end of the output shaft. The drive motor drives the steel brush to rotate and roughen the weld seam on the zinc-aluminum-magnesium welded pipe, thereby improving the roughness of the weld seam.

[0007] As a further improvement of this utility model, a hollow tube is sleeved on the outside of the output shaft, and a protective shell is fixedly connected to the end of the hollow tube. The protective shell is sleeved on the upper half of the steel brush.

[0008] As a further improvement of this utility model, the mounting base is configured as a rectangular frame structure, and a first flange is mounted on the mounting base near the drive motor.

[0009] As a further improvement of this utility model, a second flange matching the first flange is fixedly provided at the end of the drive motor, and the first flange is fixedly connected to the second flange.

[0010] As a further improvement of this utility model, a first workbench is fixedly connected to the bottom of the mounting base, and a second workbench is provided on both sides of the first workbench along the direction of the zinc-aluminum-magnesium welded pipe.

[0011] As a further improvement of this utility model, the second workbench is rotatably connected with a roller assembly and a guide clamp, which are used to transport zinc-aluminum-magnesium welded pipes.

[0012] As a further improvement of this utility model, the drive motor is mounted on the mounting base in a height-adjustable manner.

[0013] The beneficial effects of this utility model are as follows: A device for improving the roughness of the weld seam of zinc-aluminum-magnesium welded pipes is installed between the leveling equipment and the zinc spraying equipment in the existing zinc-aluminum-magnesium welded pipe production line.

[0021] In the production process of zinc-aluminum-magnesium pipelines, there are many types of pipes and the production speed is fast. After the leveling process, the surface roughness of the weld is insufficient, and the zinc application is uneven, resulting in a large number of finished products with unqualified zinc application. The only way to achieve zinc application is to manually spray zinc powder. In order to improve the zinc application effect at the weld of zinc-aluminum-magnesium welded pipe 1, a device for improving the weld roughness of zinc-aluminum-magnesium welded pipe is proposed. This device is installed between the leveling equipment and the zinc spraying equipment in the existing zinc-aluminum-magnesium welded pipe production line. It is used to improve the roughness of the weld after the zinc-aluminum-magnesium welded pipe 1 is leveled, thereby improving the zinc spraying effect.

[0022] like Figures 1-3 As shown, an apparatus for improving the weld roughness of zinc-aluminum-magnesium welded pipe 1 is mainly composed of a drive motor 2, a mounting base 6, a drive shaft, and a steel brush 7. The bottom of the steel brush 7 contacts the weld roughness at the top of the zinc-aluminum-magnesium welded pipe 1. The steel brush 7 is mounted on the drive shaft, and the output shaft is fixedly mounted on the output end of the drive motor 2. When the drive motor 2 drives the drive shaft to rotate, the steel brush 7 rotates accordingly, thereby generating friction with the weld roughness on the forward-conveyed zinc-aluminum-magnesium welded pipe 1. The steel brush 7 leaves small pits on the smoothed weld surface, thereby improving the roughness of the weld roughness. When zinc is sprayed using a zinc spray gun in the subsequent process, the surface adhesion is improved, and the zinc spraying effect is enhanced.

[0023] As a further solution, the steel brush 7 is detachably mounted on the drive shaft for easy replacement after prolonged use. The steel brush 7 is configured as a structure consisting of an annular inner shell and multiple steel wires fixed to the outside of the inner shell.

[0024] In some alternative embodiments, a hollow tube 5 is sleeved on the outside of the output shaft, and a protective shell 8 is fixedly connected to the end of the hollow tube 5. The protective shell 8 is sleeved on the upper half of the steel brush 7, wherein one end of the hollow tube 5 is fixedly installed on the first flange 4. The hollow tube 5 can be set as a round tube or a square tube. The protective shell 8 mainly serves to prevent debris from splashing.

[0025] In some alternative embodiments, the mounting base 6 is configured as a rectangular frame structure, and a first flange 4 is mounted on the mounting base 6 near the drive motor 2, wherein the output shaft passes through the through hole in the middle of the mounting base 6.

[0026] Furthermore, a second flange that matches the first flange 4 is fixedly provided at the end of the drive motor 2. The first flange 4 is fixedly connected to the second flange, for example, by bolts, and is fixedly installed on the mounting base 6.

[0027] In some alternative embodiments, a first workbench 11 is fixedly connected to the bottom of the mounting base 6, and a second workbench 12 is provided on both sides of the first workbench 11 along the direction of the zinc-aluminum-magnesium welded pipe 1.

[0028] Furthermore, the second workbench 12 is rotatably connected to a roller assembly 9 and a guide clamp 10, which are used to transport the zinc-aluminum-magnesium welded pipe 1.

[0029] The tops of the first workbench 11 and the second workbench 12 are flush. The roller group 9 consists of two rollers that are commonly set in pairs in the prior art. One of the rollers is driven to rotate, which drives the zinc-aluminum-magnesium welded pipe 1 to move on the production line. After passing through the steel brush 7, the roughness of the weld seam of the zinc-aluminum-magnesium welded pipe 1 is improved. It is then transported to the spray gun for zinc replenishment.

[0030] As an optional solution, the drive motor 2 can be mounted on the mounting base 6 in a height-adjustable manner, which is convenient to adjust according to the size of the welded pipe and ensures that the steel brush 7 can contact the weld seam at the top of the zinc-aluminum-magnesium welded pipe 1.

[0031] Specifically, for example, multiple mounting holes are opened in the height direction of the mounting base 6 with a hollow rectangular hole structure, and the first flange 4 and the second flange are installed on the mounting holes at different heights by bolts, thereby realizing the height adjustment.

[0032] Or, as Figure 3As shown, a slider is provided on the first flange 4, and a groove matching the slider is provided in the height direction of the mounting base 6. The first flange 4 is slidably connected to the mounting base 6 through the slider and the groove. A lifting platform 13 is fixedly connected to the bottom of the drive motor 2. A support member 14 is fixedly connected to the bottom of the lifting platform 13. A hydraulic cylinder 15 for driving the lifting platform 13 to lift is provided at the bottom of the lifting platform 13. The support member 14 is a component with dynamic telescopic support function, such as a gas spring.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention.
