Description

A deburring device for steel pipe production Technical Field

[0001] This utility model relates to the field of steel pipe production, specifically a deburring device for steel pipe production. Background Technology

[0002] Steel pipes are long, hollow or solid tubes made of steel with cross-sections of round, square, rectangular, etc. They can be classified according to their uses as transportation pipelines, structural pipes, mechanical industry pipes, geological drilling pipes, chemical pipes, etc. Some steel pipes are made by cutting and rewinding rolled iron sheets, and then heating and shaping them. However, during the manufacturing process, burrs may remain at the joints of the iron sheets. To ensure the quality of steel pipe production, these burrs need to be removed.

[0003] However, most existing methods for deburring steel pipes still rely on manually fixing the steel pipe and then removing the burrs by scraping or grinding. During the removal process, the grinding wheel or scraper is prone to misalignment or detachment from the steel pipe, affecting the grinding effect. Furthermore, some deburring equipment is not easy to adjust the distance between the scraper and the steel pipe, resulting in incomplete burr removal and affecting the production quality of the steel pipes. Therefore, a deburring device for steel pipe production is proposed to solve the above problems. Summary of the Invention

It offers advantages such as stable conveying of steel pipes, reduced risk of deviation, and adjustable relative height between the scraper and the steel pipe. This solves the problem that existing deburring methods mostly rely on manually fixing the steel pipe and then removing burrs by scraping or grinding. During this process, the grinding wheel or scraper is prone to misalignment or detachment from the steel pipe, affecting the grinding effect. Furthermore, some deburring devices do not easily adjust the distance between the scraper and the steel pipe, resulting in incomplete burr removal and impacting the quality of the produced steel pipes.

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] As shown in Figures 1-4, a deburring device for steel pipe production includes a base 1. Four conveying devices 2, symmetrically arranged in pairs, are mounted on the top of the base 1. Two conveying wheels 3, symmetrically arranged in pairs, are fixedly connected to the outer sides of each of the four conveying devices 2. Multiple auxiliary wheels 4 are rotatably connected to the top of the base 1. A support frame 5 is fixedly connected to the top of the base 1. A lifting device 6 is installed inside the support frame 5. A fixed frame 7 is fixedly connected to the outer side of the lifting device 6. A bolt knob 8 is threadedly connected inside the fixed frame 7. A pressure block 9 located inside the fixed frame 7 is rotatably connected to the outer side of the bolt knob 8. A second limiting rod 10, slidably connected to the pressure block 9, is fixedly connected inside the fixed frame 7.

[0028] The single conveying device 2 includes a motor 21 fixedly connected to the outside of the base 1. A first transmission wheel 22 is fixedly connected to the outside of the output shaft of the motor 21. A fixed shaft 23 is rotatably connected to the outside of the base 1. A second transmission wheel 24, which is connected to the first transmission wheel 22 via a transmission belt, is fixedly connected to the outside of the fixed shaft 23. The outside of the output shaft of the motor 21 and the outside of the fixed shaft 23 are respectively fixedly connected to two conveying wheels 3.

[0029] In this embodiment, during actual use, the start of the motor 21 will drive the first transmission wheel 22 to rotate, and at the same time, the second transmission wheel 24 will also rotate under the action of the transmission belt, and the fixed shaft 23 inside it will drive the two conveying wheels 3 to rotate with the motor 21. With the cooperation of the two sets of conveying wheels, the steel pipe between them will be horizontally conveyed.

[0030] Among them, the interiors of multiple conveyor wheels 3 and multiple auxiliary wheels 4 are all arranged in an arc shape, and the multiple conveyor wheels 3 and multiple auxiliary wheels 4 are all arranged with a wider outer side and a narrower inner side.

[0031] In this embodiment, during actual use, the arc-shaped conveying wheel 3 and auxiliary wheel 4 can limit the position of the steel pipe, so as to facilitate the conveying and movement of the steel pipe and prevent the steel pipe from falling off.

[0032] The lifting device 6 includes a threaded rod 61 that is rotatably connected to the inside of the support frame 5. A knob 62 is fixedly connected to the outside of the threaded rod 61. A transmission block 63 that is fixedly connected to the fixed frame 7 is connected to the outside of the threaded rod 61 via a threaded transmission.

[0033] In this embodiment, during actual use, when the knob 62 is turned, the threaded rod 61 will rotate, and under the action of the thread, the transmission block 63 will move along the direction of the thread, and drive the fixed frame 7 and the scraper inside to adjust the height.

[0034] The support frame 5 has a first limiting rod 11 that is slidably connected to the transmission block 63, and a first threaded sleeve 12 that is threadedly connected to the outer side of the threaded rod 61.

[0035] In this embodiment, during actual use, the first limiting rod 11 and the threaded rod 61 are set parallel to each other, so that they can limit and stabilize the movement direction of the transmission block 63. The first threaded sleeve 12 can limit the position of the threaded rod 61 and prevent the threaded rod 61 from rotating by shims, washers, etc., so as to stabilize the position of the transmission block 63.

[0036] Among them, the outer thread of the bolt knob 8 is connected to the second threaded sleeve 13, the pressure block 9 is U-shaped, and the inside of the fixing frame 7 is provided with a U-shaped groove.

[0037] In this embodiment, during actual use, the second threaded sleeve 13 functions in the same way as the first threaded sleeve 12, which facilitates the limitation of the position of the bolt knob 8. The U-shaped pressure block 9 cooperates with the U-shaped groove to press and fix the scraper. A rubber pad can be provided on the outside of the pressure block 9 to enhance the pressing friction on the scraper and prevent it from falling off.

[0038] Working principle:

[0039] When scraping off burrs from steel pipes, the scraper can first be placed inside the U-shaped groove of the fixed frame 7. The position of the pressure block 9 can be adjusted by turning the bolt knob 8, and the scraper can be fixed inside the fixed frame 7 by tightening the second threaded sleeve 13. Then, the vertical height of the scraper inside the fixed frame 7 can be adjusted by turning the knob 62 so that it fits the surface of the steel pipe. The steel pipe is inserted between the conveyor wheels 3 with the mating surface facing upward. Under the rotation of the conveyor wheels 3 and the limiting support of the auxiliary wheels 4, the steel pipe is not easy to flip over and can pass smoothly under the scraper and have the burrs removed by the scraper.
