Description

Technical Field

[0001] This utility model relates to the field of steel pipe surface pretreatment, and more specifically, to an integrated machine for steel pipe surface pretreatment. Background Technology

[0002] A steel pipe surface pretreatment integrated machine is a device used for automated and integrated treatment of steel pipe surfaces. It is mainly used to remove impurities such as rust, scale, and oil stains from the steel pipe surface and form a surface condition suitable for subsequent processing (such as painting, welding, galvanizing, etc.). This type of equipment integrates multiple processing functions to achieve efficient and continuous pretreatment operations and is widely used in petroleum, chemical, construction, and machinery manufacturing fields.

[0003] Traditional processes typically employ shot blasting, sandblasting, or grinding to remove surface rust, scale, and impurities. However, these individual treatment methods have significant limitations: during the transport of steel pipes, the polished surface is prone to retaining rust fragments, abrasive particles, and other impurities. These impurities can scratch the surface of the steel pipe during subsequent transport, forming defects such as scratches and pits. This not only reduces surface smoothness but also affects coating adhesion, leading to problems such as coating peeling and unevenness in subsequent painting and galvanizing processes. In view of this, we propose an integrated steel pipe surface pretreatment machine. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned shortcomings and provide an integrated steel pipe surface pretreatment machine, which solves the limitations of traditional steel pipe surface pretreatment methods such as shot blasting, sandblasting, and grinding. After treatment, the steel pipe is easily transported with residual rust and other impurities, which scratch the surface and form defects, affecting the smoothness and coating adhesion, resulting in poor coating and galvanizing quality. To achieve the above objectives, this utility model provides an integrated steel pipe surface pretreatment machine, including an operating table. Two feeding mechanisms are symmetrically distributed on the top of the operating table. Each feeding mechanism includes a bracket fixedly connected to the top surface of the operating table. An adjusting plate is slidably connected inside the bracket. Wiping components are fixedly connected to both sides of the adjusting plate. The wiping assembly includes a first arc-shaped base symmetrically distributed on both sides of the adjustment plate. A first sponge pad is fixedly connected inside the first arc-shaped base by bolts. A second arc-shaped base is provided below the first arc-shaped base, and a second sponge pad is fixedly connected inside the second arc-shaped base by bolts.

[0005] The beneficial effects of this utility model are: In this invention, the synchronous movement of the adjusting plate and the wiping component enables precise positioning of steel pipes of different diameters, ensuring that the steel pipes remain stable during transmission and preventing shaking or deviation caused by differences in pipe diameter. At the same time, the outer wall of the steel pipe is tightly fitted with the inner walls of the first and second sponge pads. The soft and elastic material of the sponge pads can thoroughly remove residual rust fragments, abrasive particles, dust and other impurities through friction without damaging the surface of the steel pipe.

[0006] As a further improvement to this technical solution, a threaded rod is threadedly connected to the inner wall of the bracket, and the bottom end of the threaded rod is fixedly connected to the top of the adjusting plate through a bearing; the front and back of the bracket are provided with sliding grooves for the movement of the adjusting plate, and the sides of the bracket are provided with sliding rails for the sliding of the first arc-shaped base, and the sliding rails are adapted to the first arc-shaped base; two first transport wheels are rotatably connected to the bottom of the bracket, and a drive motor is fixedly installed on one side of the front of the bracket; the output end of the drive motor is splinedly connected to the output end of one of the first transport wheels; a second transport wheel is rotatably connected to the inside of the adjusting plate; the second arc-shaped base is fixedly connected to the side of the bracket and located below the first arc-shaped base; the first sponge pad and the second sponge pad are both arc-shaped and used to wipe the polished steel pipe.

[0007] The beneficial effect of adopting the above-mentioned further solution is that, through the threaded engagement between the threaded rod and the inner wall of the bracket, when the threaded rod is rotated, the adjusting plate can be driven to move smoothly up and down along the slide groove on the bracket. At the same time, the first arc-shaped base on both sides of the adjusting plate slides synchronously in the sliding rail, so that the first sponge pad and the second sponge pad can flexibly adapt to the outer diameter of steel pipes of different diameters, realize the precise clamping and limiting of the steel pipe, and avoid the steel pipe from shaking or deviating during the transmission process.

[0008] As a further improvement to this technical solution, a polishing mechanism is also fixedly installed on the top of the operating table. The polishing mechanism includes a movable plate fixedly installed on the top surface of the operating table. A motor is fixedly installed on the movable plate, and a grinding disc is splinedly connected to the output end of the motor. A sliding plate is slidably connected to the top surface of the movable plate. The top surface of the sliding plate is fixedly connected to the bottom surface of the motor, and a threaded screw is threadedly connected to the inside of the sliding plate. One end of the threaded screw is rotatably connected to the inner wall of the movable plate through a bearing. Two placement compartments are symmetrically installed on both sides of the operating table, which are used to place steel pipes before and after processing, respectively.

[0009] The beneficial effects of adopting the above-mentioned further solution are that the motor drives the grinding disc to rotate at high speed to polish the surface of the steel pipe, removing impurities such as rust and oxide scale. The combination structure of the moving plate and the sliding plate ensures that the grinding disc can stably keep close to the surface of the steel pipe, maintain uniform grinding force during the polishing process, and effectively improve the polishing quality and surface flatness.

[0010] This integrated steel pipe surface pretreatment machine, by rotating a threaded rod, drives an adjusting plate to slide vertically within a groove in a support frame. The first arc-shaped bases on both sides of the adjusting plate move synchronously along the sliding rail, allowing the first and second sponge pads to tightly wrap steel pipes of different diameters, achieving precise positioning. Simultaneously, the drive motor at the bottom of the support frame drives the first transport wheel to rotate, and the second transport wheel inside the adjusting plate rotates in coordination, stably conveying the steel pipe. During this process, the outer wall of the steel pipe makes full contact with the inner wall of the sponge pad. The flexible wiping of the sponge pad thoroughly removes impurities such as rust debris and abrasive particles remaining after polishing, preventing these impurities from scratching the surface and causing scratches or dents during the steel pipe's transport.

Detailed Implementation

[0013] 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.

[0014] The present invention provides the following preferred embodiments. Please see Figures 1-4As shown, this embodiment provides an integrated machine for surface pretreatment of steel pipes, including an operating table 100. Two feeding mechanisms 200 are symmetrically distributed on the top of the operating table 100. Both feeding mechanisms 200 include a bracket 201 fixedly connected to the top surface of the operating table 100. An adjusting plate 204 is slidably connected inside the bracket 201. Wiping components 203 are fixedly connected to both sides of the adjusting plate 204. Only the feeding mechanism 200 on the right side includes the wiping component 203. The wiping assembly 203 includes a first arc-shaped base 2031 stacked on both sides of the adjustment plate 204. A first sponge pad 2032 is fixedly connected inside the first arc-shaped base 2031 by bolts. A second arc-shaped base is provided below the first arc-shaped base 2031, and a second sponge pad 2033 is fixedly connected inside the second arc-shaped base by bolts.

[0015] The improvement in this embodiment is as follows: In the pretreatment stage of steel pipe surface, traditional processes often use polishing equipment to remove rust from the steel pipe surface. However, this method has limitations. Due to the high likelihood of impurities remaining on the steel pipe during transportation, including incompletely removed rust debris, abrasive particles generated during polishing, and dust adhering to the environment, these residual impurities can cause defects such as scratches and pits on the steel pipe surface, reducing surface smoothness and affecting the adhesion of subsequent coating, galvanizing, and other processes, resulting in coating peeling or unevenness. Therefore, by adjusting the synchronous movement of the plate 204 and the wiping component 203, precise positioning of steel pipes of different diameters can be achieved. Furthermore, during the transportation of the steel pipe, its outer wall will come into close contact with the inner walls of the first sponge pad 2032 and the second sponge pad 2033. Utilizing the soft material of the sponge pads and the wiping action, the residual impurities on the steel pipe surface are effectively removed. Eliminating impurities avoids defects such as scratches and pits on the steel pipe surface, significantly improves surface smoothness, provides a high-quality base for subsequent coating, galvanizing, and other processes, and enhances coating adhesion and uniformity.

[0016] Based on the above, the specific structure will be disclosed in detail: To achieve the up-and-down movement of the adjusting plate 204, as follows: Figure 1 and Figure 2 As shown, a threaded rod 205 is threadedly connected to the inner wall of the bracket 201. The bottom end of the threaded rod 205 is fixedly connected to the top of the adjusting plate 204 through a bearing. By rotating the handle at the top of the threaded rod 205, the threaded rod 205 is driven to rotate, which in turn drives the adjusting plate 204 to move horizontally, which is beneficial for limiting the movement of steel pipes of different diameters.

[0017] It is worth mentioning that the front and back of the bracket 201 are provided with sliding grooves for the movement of the adjustment plate 204, and the sides of the bracket 201 are provided with sliding rails 2011 for the sliding of the first arc-shaped base 2031. The sliding rails 2011 are adapted to the first arc-shaped base 2031. The design of the sliding grooves and sliding rails 2011 helps to improve the stability of the feeding mechanism 200 when it moves.

[0018] Specifically, two first transport wheels 206 are rotatably connected to the bottom of the bracket 201, and a drive motor is fixedly installed on one side of the front of the bracket 201. The output end of the drive motor is splinedly connected to the output end of one of the first transport wheels 206. A second transport wheel is rotatably connected inside the adjusting plate 204. Therefore, the adjusting plate 204 drives the second transport wheel to move downward to a position where it is in contact with the outer wall of the steel pipe, so that the outer wall of the steel pipe is in contact with the first transport wheel 206 and the second transport wheel respectively. Then, the drive motor drives the first transport wheel 206 to rotate, and so on. When cutting the steel pipe, on the one hand, the adjusting plate 204 can flexibly adjust the position of the second transport wheel to adapt to steel pipes of different outer diameters. By dynamically adjusting the distance between the two wheels, the equipment can adapt to the cutting needs of multiple specifications of steel pipes without changing the hardware, reducing mold change time and cost, and improving the versatility of the equipment. On the other hand, the first transport wheel 206 and the second transport wheel are attached to the outer wall of the steel pipe to form a clamping structure. The friction force is used to drive the steel pipe to move evenly, preventing the steel pipe from shaking, deviating or jamming due to unilateral force during the transmission process, and ensuring that the cutting process is stable and orderly.

[0019] Furthermore, to achieve cleaning of the steel pipe surface after polishing, the wiping component 203 is disclosed in detail, such as... Figure 1 As shown, the second arc-shaped base is fixedly connected to the side of the bracket 201 and located below the first arc-shaped base 2031. The first sponge pad 2032 and the second sponge pad 2033 are both arc-shaped and used to wipe the polished steel pipe. The downward movement of the adjusting plate 204 drives the first arc-shaped base 2031 and the first sponge pad 2032 to move downward, so that the outer wall of the steel pipe is tightly wrapped by the first sponge pad 2032 and the second sponge pad 2033. When the first transport wheel 206 and the second transport wheel drive the steel pipe to move and implement the steel pipe unloading, the steel pipe is wiped while being unloaded. The close contact between the sponge pad and the outer wall of the steel pipe forms a wiping force, which removes residual rust, dust, oil and other impurities during the steel pipe transmission process. In addition, the arc-shaped sponge pad design can be adapted to the curved surface of steel pipes of different diameters to ensure that the outer wall is cleaned without dead corners in the entire circumference, especially for complex parts such as welds and dents.

[0020] However, to achieve polishing of steel pipes, specifically as follows: Figure 3As shown, a polishing mechanism 300 is also fixedly installed on the top of the operating table 100. The polishing mechanism 300 includes a movable plate 301 fixedly installed on the top surface of the operating table 100. A motor is fixedly installed on the movable plate 301, and a grinding disc 302 is splinedly connected to the output end of the motor. A sliding plate is slidably connected to the top surface of the movable plate 301. The top surface of the sliding plate is fixedly connected to the bottom surface of the motor, and a threaded screw is threadedly connected to the inside of the sliding plate. One end of the threaded screw is rotatably connected to the inner wall of the movable plate 301 through a bearing. By rotating the threaded screw, the two movable plates 301 are moved to a suitable position, so that the two grinding discs 302 can fit against the outer wall of the steel pipe. The motor is started, and the two motors drive the two grinding discs 302 to rotate and polish the steel pipe. This is beneficial for polishing steel pipes of different diameters. The two grinding discs 302 rotate in opposite directions. Specifically, two placement compartments are symmetrically installed on both sides of the operating table 100, which are used to place steel pipes before and after processing, respectively.

[0021] In practical use, this utility model of an integrated steel pipe surface pretreatment machine is as follows: First, one end of the steel pipe is placed in the unloading mechanism 200 without the wiping component 203. The drive motor drives the first transport wheel 206 to rotate. At the same time, the second transport wheel inside the adjusting plate 204 cooperates with the first transport wheel 206 to transport the steel pipe smoothly. After the steel pipe is transported to the polishing mechanism 300 at the top of the operating table 100, the position of the sliding plate is adjusted by rotating the threaded screw, thereby adjusting the relative position of the motor and the polishing disc 302 with the steel pipe. After the adjustment is in place, the motor drives the polishing disc 302 to rotate and polish the surface of the steel pipe. After polishing, the steel pipe is fed into the unloading mechanism 200 with the wiping component 203. The position of the wiping component 203 and the second transport wheel is adjusted by the adjusting plate 204, so that the first sponge pad 2032 and the second sponge pad 2033 can fit the outer diameter of the steel pipe and tightly wrap the steel pipe. During the movement of the steel pipe, the first sponge pad 2032 and the second sponge pad 2033 wipe the surface of the steel pipe to remove residual impurities. The polished steel pipe is transported by the unloading mechanism 200 to the storage bin on one side of the operating table 100 for storage, waiting for subsequent processing.
