Description

Technical Field

[0001] This utility model relates to the field of welded pipe processing technology, and in particular to a rust removal device for welded pipe processing. Background Technology

[0002] Welded pipe processing is a complex process involving multiple steps, aiming to transform metal strip or other raw materials into welded steel pipes with the required dimensions, shapes, and properties through a series of technological steps. Welded pipe processing begins with the preparation of raw materials, which includes selecting suitable metal strips, such as steel strips or plates, and preparing auxiliary materials required for welding, such as welding wire and flux. Raw materials must undergo rigorous quality inspection to ensure that their chemical composition, mechanical properties, and surface quality meet processing requirements. Next, the raw materials undergo pretreatment steps, such as leveling, shearing, and edge treatment, to eliminate bending, waviness, and edge defects in the strip, providing a good foundation for subsequent forming and welding processes. Forming is one of the key steps in welded pipe processing. In this stage, the metal strip is bent into a tubular shape by a forming unit, forming a continuous tube. The forming unit typically includes a series of forming rollers that gradually deform the strip into the desired tubular shape through progressive bending and forming. The forming process requires precise control to ensure that the diameter, wall thickness, and shape accuracy of the tube meet design requirements. Welding is the core step in welded pipe processing. On the formed pipe, welding equipment melts the joint of the pipe using electric arc heating or other methods, and fills it with welding wire to form a weld, thus achieving a permanent connection between the pipes. During the welding process, welding parameters, such as welding current, voltage, and speed, need to be strictly controlled to ensure weld quality. Simultaneously, necessary post-processing is required for the weld, such as grinding and polishing, to improve its appearance and performance. Welded pipe processing also includes a series of post-processing steps, such as sizing, straightening, cutting, and inspection. Sizing and straightening steps are used to adjust the diameter and straightness of the welded pipe to meet customer requirements. The cutting step cuts the continuous welded pipe to the required length as needed. Finally, the inspection step conducts a comprehensive quality check of the welded pipe, including appearance quality, dimensional accuracy, mechanical properties, and chemical composition, to ensure that the quality of the welded pipe meets relevant standards and regulations. Throughout the entire welded pipe processing process, advanced equipment and technologies are required to improve production efficiency and product quality. For example, the application of automation and intelligent technologies can achieve a high degree of automation and intelligent control in welded pipe processing, reducing manual intervention and errors; while high-precision testing equipment can accurately measure and evaluate the quality of welded pipes, ensuring the stability and reliability of product quality.

[0003] Rust removal is a crucial pretreatment step in welded pipe processing, directly impacting the quality of subsequent welding and processing. Before processing, welded pipes may have contaminants such as rust, scale, and oil on their surface. These contaminants not only affect the appearance of the welded pipe but also adversely affect the welding process, leading to increased weld defects and reduced weld strength. Therefore, thorough rust removal before welded pipe processing is essential. Various rust removal methods exist, and different methods can be selected based on the severity of the rust, the material of the welded pipe, and processing requirements. One method involves grinding the surface of the welded pipe using tools such as wire brushes, grinding wheels, and polishing machines to remove rust and scale. This method is suitable for welded pipes with light rust and produces a high degree of surface smoothness. Another method involves immersing or spraying the surface of the welded pipe with pickling solution, using a chemical reaction to dissolve the rust and scale. This method is fast, but attention must be paid to the environmental and human hazards of pickling solutions and the resulting waste pickling solution.

[0004] In the process of rust removal for welded pipes, it is necessary to improve the overall efficiency and effect of rust removal. However, considering that the traditional method of rust removal for welded pipes involves directly immersing the welded pipes in the rust removal liquid, which lacks a cleaning function, residual impurities will re-adhere to the welded pipes, thus affecting the overall effect of welded pipe processing and causing great inconvenience. Therefore, there is an urgent need for a rust removal device for welded pipe processing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a rust removal device for welded pipe processing, which solves the problem in the prior art where the welded pipe is directly placed in the rust removal liquid for rust removal, which lacks a cleaning function. This causes residual impurities to re-adhere to the welded pipe, thus affecting the overall effect of welded pipe processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rust removal device for welded pipe processing includes a frame. A filter plate is fixedly connected to the lower inner side of the frame, and a bidirectional screw is rotatably connected to the upper inner side of the frame. A drive motor is fixedly connected to the outer wall of the frame by bolts. One end of the bidirectional screw passes through the side wall of the frame and is connected to the output shaft of the drive motor. Both ends of the bidirectional screw are threadedly connected to nut seats. A support plate is fixedly connected to the bottom of one side of each nut seat, and a support groove is opened on the top of each support plate. A bearing plate is provided on the inner side of the frame, and several sets of arc-shaped plates are provided at the bottom of the bearing plate. Each set of arc-shaped plates has two plates, and the two arc-shaped plates are fixedly connected to each other by bolts. A cleaning brush is fixedly connected to the inner side of all the arc-shaped plates. A connecting plate is fixedly connected to the top of the bearing plate, and a cylinder is fixedly connected to the outer wall of the frame by bolts. The output shaft of the cylinder passes through the side wall of the frame and is fixedly connected to one side of the connecting plate.

[0008] Preferably, both outer sides of the frame are connected to doors via hinges, and a bottom valve is installed on one side of the lower part of the frame.

[0009] Preferably, a sliding rod is fixedly connected to one side of the inner side of the frame, and a sliding sleeve is fitted at one end of the sliding rod, and the outer wall of the sliding sleeve is fixedly connected to the top of the bearing plate.

[0010] Preferably, one end of the bidirectional screw is rotatably connected to the inner wall of the frame via a rotating shaft, and the other end of the bidirectional screw passes through the side wall of the frame via a bearing sleeve.

[0011] Preferably, a fixing plate is fixedly connected to one side of the bottom of each of the two nut seats, and one side of each fixing plate is fixedly connected to one side of each of the two support plates.

[0012] Preferably, each of the two support plates has a slider fixedly connected to one side, and both sliders are slidably connected to the side wall of the frame through a groove.

[0013] This utility model has the following beneficial effects:

[0014] First, open the door and place the pipes to be derusted one by one into the support grooves at the top of the support plate. Each set of arc-shaped plates is fitted onto the pipe. Add a certain amount of derusting liquid to the frame. While the pipes are soaked in the derusting liquid, the support plate moves, which drives the cleaning brushes in all the arc-shaped plates to clean the pipes, thoroughly removing impurities attached to them. At the same time, the drive motor can be started to drive the bidirectional screw to rotate, which moves the two support plates through the two nut seats to support pipes of different lengths. Compared with the existing technology of directly placing the welded pipe into the derusting liquid for derusting when welding, which lacks a cleaning function, and causes residual impurities to re-adhere to the welded pipe, thus affecting the overall effect of welded pipe processing, the method proposed in this utility model uses the arc-shaped plates at the bottom of the support plate to clean the pipes, which, together with the derusting liquid, thoroughly cleans the pipes, greatly improving the efficiency of pipe derusting and making it highly practical.
