Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a rust removal device for the outer wall of steel pipes. Background Technology

[0002] Due to limitations in storage conditions, steel pipes are susceptible to oxide corrosion. This corrosion is generally chemical corrosion, which is slow and leaves a thin, porous, brown rust layer on the surface. The presence of moisture in the air can slowly create perforations. Therefore, rust removal is necessary before use to prevent further corrosion. During machining, the outer wall of the steel pipe must be thoroughly derusted before use. Currently, traditional rust removal methods mostly rely on manual methods, which are labor-intensive, inefficient, and cannot flexibly adjust to the length of the pipe. Furthermore, if rust debris is not promptly removed, it can pollute the work environment and harm workers' health. Utility Model Content

[0019] 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.

[0020] like Figure 1 and Figure 2 As shown, a rust removal device for the outer wall of a steel pipe includes a rust removal operation system and a material conveying system. The rust removal operation system includes a steel pipe fixing assembly and a cleaning and rust removal system. The steel pipe fixing assembly includes an active clamping assembly, a passive clamping assembly, and a drive motor 18. The active clamping assembly includes a first clamping block 11, a sliding platform 12, a sliding rail 13, and a clamping driver 14. The drive motor 18 is fixed on the sliding platform 12, and its output shaft is connected to the first clamping block 11. The passive clamping assembly includes a second clamping block 15, a follower shaft 16, and a fixed platform 17. The second clamping block 15 is rotatably connected to the fixed platform 17 through the follower shaft 16. The cleaning and rust removal system includes a moving assembly, a rust removal assembly, and a debris collection system. The rust removal assembly is connected to the moving assembly and includes a protective cover 23 and a rust removal brush head 24. The debris collection system includes a dust collection port 25, an air duct 26, and a fan. The dust collection port 25 is located inside the protective cover 23 and is connected to the fan through the air duct 26.

[0021] In use, when the steel pipe is transported by the material conveying system to the space between the active clamping component and the passive clamping component, the clamping driver 14 pushes the sliding platform 12 to move along the sliding track 13, and then fixes the steel pipe between the first clamping block 11 and the second clamping block 15; the drive motor 18 drives the first clamping block 11 to rotate, causing the steel pipe to rotate, and the moving component drives the rust removal component to move close to the steel pipe, and performs rust removal operation on the steel pipe while moving; when performing rust removal operation, the rust removal brush head 24 actively rotates to grind and remove rust from the surface of the steel pipe, and in conjunction with the rotation of the steel pipe and the movement of the rust removal component, the surface of the steel pipe is thoroughly ground and rust removed;

[0022] Confining the rust removal operation to the limited space within the protective cover 23 effectively prevents sparks or debris from polluting the environment or injuring operators. In practical applications, the dust collection port 25 faces the rust removal brush head 24, and the debris generated during rust removal will be sucked away by the debris collection system. Furthermore, a debris collection trough 251 is provided at the lower end of the dust collection port 25, where larger pieces of debris will fall and be collected, maximizing the cleanliness of the work surface and minimizing the harm to operators and the impact on the environment caused by debris splashing.

[0023] In practical applications, there are various ways to move the rust removal component. In this embodiment, the moving component includes a movable track 21 and a mechanical swing arm 22. The rust removal component is connected to the movable track 21 through the mechanical swing arm 22. The mechanical swing arm 22 and the rust removal component as a whole can move back and forth along the movable track 21. The mechanical swing arm 22 has a certain pitching ability and can drive the rust removal component to be raised and lowered.

[0024] When the steel pipe is fixed in place and rust removal is required, the mechanical swing arm 22 controls the rust removal component to be lowered, so that the protective cover 23 covers the steel pipe and the rust removal brush head 24 contacts the outer wall of the steel pipe. When the rust removal is completed, the mechanical swing arm 22 drives the rust removal component to be raised, the steel pipe fixing component lowers the rust-removed steel pipe, and the material conveying system transports the rust-removed steel pipe away and transports the next steel pipe to the position of the steel pipe fixing component.

[0025] The first clamping block 11 and the second clamping block 15 are coaxially arranged opposite each other; the outer diameter of the first clamping block 11 and the second clamping block 15 gradually increases from the side facing the steel pipe to the side away from the steel pipe; in practical applications, the two clamping blocks can adopt a conical or frustum-shaped design, which can be adapted to steel pipes of various diameters. The sliding platform 12 of the active clamping component has a certain stroke, which can be adapted to steel pipes within a certain length range, making the use of the rust removal device more flexible and its application range wider.

[0026] In practical applications, the clamping actuator 14 is a hydraulic cylinder or a pneumatic cylinder.

[0027] The debris collection trough 251 and the dust collection port 25 are connected in a detachable manner, which facilitates regular cleaning and maintenance.

[0028] Furthermore, a protective curtain 231 is provided at the lower edge of the protective cover 23, which can increase the protection range and prevent debris and sparks from flying during rust removal.

[0029] The material conveying system includes a conveyor belt 31 and several steel pipe slots 32 fixed on the conveyor belt. In use, the steel pipes are placed in the steel pipe slots 32 and move with the conveyor belt 31.

[0030] Advantages of this utility model:

[0031] The cleaning and rust removal system includes a moving component, a rust removal component, and a debris collection system. It can effectively collect debris during rust removal operations, reducing environmental pollution and making the operation safer. The steel pipe fixing component includes an active clamping component, a passive clamping component, and a drive motor, which can adapt to steel pipes of different lengths and diameters, making it more versatile and flexible in use. Combined with a material conveying system, it can perform continuous batch rust removal operations, greatly improving efficiency.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
