[0030] The present application provides a water-penetrating pipe anti-scratching device, which comprises an inlet assembly and an outlet guide wheel set fixedly connected to two ends of a water-penetrating pipe, wherein

[0031] The import assembly comprises a guide horn 1 and an import guide wheel set, the outlet end of the import guide wheel set is fixed to the inlet end of the water-penetrating pipe, the guide horn 1 is fixed to the inlet end of the import guide wheel set and the flared end of the guide horn 1 extends along the central axis of the water-penetrating pipe towards the direction away from the water-penetrating pipe;

[0032] The inlet end of the export guide wheel set is fixed to the outlet end of the water-penetrating pipe, and the outlet end of the export guide wheel set extends towards the direction away from the water-penetrating pipe;

[0033] The import guide wheel set and the export guide wheel set each comprise at least one pair of vertically arranged first guide wheels 2 and one horizontally arranged second guide wheel 3, and a gap for the passage of the rolled piece is formed between the first guide wheels 2 and the second guide wheel 3.

[0034] According to the above technical scheme, the import assembly and the export guide wheel set are arranged at the two ends of the water-penetrating pipe, the import assembly comprises a guide horn 1 and an import guide wheel set, the outlet end of the import guide wheel set is fixed to the inlet end of the water-penetrating pipe, the guide horn 1 is fixed to the inlet end of the import guide wheel set and the flared end of the guide horn 1 extends along the central axis of the water-penetrating pipe towards the direction away from the water-penetrating pipe; the inlet end of the export guide wheel set is fixed to the outlet end of the water-penetrating pipe, and the outlet end of the export guide wheel set extends towards the direction away from the water-penetrating pipe. The import guide wheel set and the export guide wheel set each comprise at least one pair of vertically arranged first guide wheels 2 and one horizontally arranged second guide wheel 3, and a gap for the passage of the rolled piece is formed between the first guide wheels 2 and the second guide wheel 3. The three-surface adjustable anti-scratching guide wheel is adopted, when the rolled piece enters the water-penetrating pipe from the guide horn 1 through the water-penetrating pipe anti-scratching device, the rolled piece running direction can be controlled by adjusting the guide wheel according to the running direction of the red steel in the production process, and the problem of the water-penetrating pipe being scratched due to the rolled piece swinging and scratching the inner wall when passing through the water-penetrating pipe is avoided.

[0035] Referring to Figure 1In this embodiment, to optimize the structure of the anti-scratch device for the water pipe, preferably, the guide wheel assembly includes a pair of vertical U-shaped plates 4 fixed to the guide bell mouth 1. A gap is formed between the two vertical U-shaped plates 4 for the workpiece to pass through. The two ends of the second guide wheel 3 are detachably mounted in the grooves 5 on the two vertical U-shaped plates and located below the workpiece, configured to be able to adhere to the workpiece from the bottom. A pair of flat plates 6 are connected between the pair of vertical U-shaped plates 4 and the inlet end of the water pipe. A pair of first guide wheels 2 are symmetrically arranged between the pair of flat plates 6 and cooperate with the flat plates 6 to form a gap for the workpiece to pass through and enter the water pipe. The pair of first guide wheels 2 are configured to be able to adhere to the workpiece from the side at the same time. In this way, when the workpiece enters from the guide bell mouth 1 and then enters the gap between the pair of vertical U-shaped plates 4, it encounters the second guide wheel 3, which will adhere to the workpiece from the bottom and lift the workpiece upward. At this point, the rolled piece continues to move forward. When it passes a pair of vertically arranged first guide rollers 2, the two first guide rollers 2 simultaneously press and squeeze the rolled piece from the side. This can work with the second guide roller 3 to achieve a state where the rolled piece is constrained from three sides when it enters the water pipe, thus preventing the rolled piece from swinging and scraping against the inner wall of the water pipe after entering it, which would cause the water pipe to be scratched.

[0036] like Figure 2 As shown, in this embodiment, in order to optimize the structure of the anti-scratch device for the water pipe, preferably, the above-mentioned guide wheel assembly includes a pair of flat plates 6 fixed to the outlet end of the water pipe, and a pair of first guide wheels 2 symmetrically arranged between the pair of flat plates 6 and cooperate with the flat plates 6 to form a gap for the rolled piece to pass through and enter the water pipe. The pair of first guide wheels 2 are configured to be able to simultaneously adhere to the rolled piece from the side. A guide wheel frame 7 extending in a direction away from the water pipe is formed on the lower flat plate 6, and a second guide wheel 3 is mounted on the guide wheel frame 7 and configured to adhere to the rolled piece from the bottom. In this way, when the rolled piece passes through the water pipe and extends out of the water pipe, it first enters the gap between a pair of first guide rollers 2. The two first guide rollers 2 simultaneously press and squeeze the rolled piece from the side. As the rolled piece continues to move forward, it encounters the second guide roller 3, which then presses against the rolled piece from the bottom and lifts it upward. This can work with the second guide roller 3 to achieve a state where the rolled piece is constrained from three sides at the same time. This allows the guide roller group and the guide roller group to work together end to end, constraining the direction of the rolled piece from beginning to end. This effectively solves the problem of the rolled piece swinging inside the water pipe and avoids it scraping against the inner wall and causing scratches on the water pipe.

[0037] The diameter of the different pin is different, in this embodiment, in order to make the water pipe anti scratch device can be applied to different pin, preferably, the first guide wheel 2 is installed to the flat plate 6 through the eccentric shaft 8, for adjusting the distance between the two first guide wheels 2. In this way, by adjusting the inner diameter size between the guide wheels, the scratch of the rolling piece on the inner wall of the water pipe is avoided, which can effectively support the running direction of the red steel. If the guide wheel cannot approach the red steel during production, the post personnel only needs to slightly adjust the eccentric shaft.

[0038] In actual use, the second guide wheel 3 is slightly higher than the bottom of the water pipe as the bottom wheel. If the height needs to be adjusted when encountering different specifications of the pin, different V-shaped wheels or flat wheels can be used. At this time, in order to facilitate the operator to replace the second guide wheel 3, a handle 9 is connected to the shaft of the second guide wheel 3. In this way, the operator can easily take out and replace the second guide wheel 3 from the vertical U-shaped plate 4 or the guide wheel frame 7 by holding the handle 9.

[0039] In addition, in this embodiment, the first guide wheel 2 is preferably a flat wheel, and the second guide wheel 3 is also preferably a flat wheel or a U-shaped wheel. In this way, if the horizontal position of the second guide wheel 3 is too low, the U-shaped wheel can be replaced with a flat wheel when rubbing the bottom plate to solve this problem.

[0040] In addition, in order to improve the mechanical strength and structural stability of the water pipe anti scratch device, the guide horn 1, the vertical U-shaped plate 4, the flat plate 6 and the guide wheel frame 7 are preferably made of steel plates, and the above fixing and connecting mode is welding fixation.

[0041] The guide horn 1, the vertical U-shaped plate 4, the flat plate 6 and the guide wheel frame 7 made of steel plates have a long service life, but their external profiles are also sharp, and once the operator is slightly careless, it is easy to cause scratches. In order to avoid the above situation, a fillet is preferably provided at the edge of the guide horn 1, the vertical U-shaped plate 4, the flat plate 6 and the guide wheel frame 7. After installation, the welding part can also be polished to make it smooth and flat. In actual processing and manufacturing, the water pipe anti scratch device can use existing guide wheels and scrap guide support arms for modification, which is easy to manufacture and maintain, and realizes low investment cost. After being put into use, the operation is simple, the post can adjust the guide wheel at any time, which is convenient and fast, has low failure rate, is convenient for later maintenance and maintenance, truly effectively prevents the scratch of the water pipe, reduces the quality accident, improves the production efficiency, and creates favorable conditions for the later special steel production.

[0042] The preferred embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited thereto. Within the technical concept of the present application, various simple modifications can be made to the technical solution of the present application, including the combination of various specific technical features in any suitable manner. In order to avoid unnecessary repetition, the present application will not further describe various possible combination manners. However, these simple modifications and combinations should also be considered as disclosed content of the present application, and all belong to the protection scope of the present application.
