Description

Technical Field

[0001] The utility model relates to the technical field of mechanical part rust removal, in particular to a rust removal device for mechanical parts. Background Art

[0002] The rusting of mechanical parts is mainly due to the chemical reaction of metals with oxygen, moisture, etc. in the air. When the protective layer on the part surface is damaged or non-existent, oxygen and moisture are likely to come into contact with the metal surface, triggering an oxidation reaction and forming a rust layer. In addition, some special environmental factors such as corrosive gases, chemical substances, high temperature and high humidity will also accelerate the rusting process of mechanical parts. During use, parts may be subjected to external forces such as friction and collision, damaging the surface protection and creating conditions for rusting. At the same time, if parts are left idle for a long time and lack maintenance, they are also prone to rusting. Therefore, it is necessary to remove rust from rusted mechanical parts. Among them, steel pipes are common mechanical parts. At present, sandblasting rust removal equipment is relatively common, which can remove rust and is suitable for the rust removal of various mechanical parts, playing an important role in industrial production.

[0003] However, when the existing sandblasting rust removal device is in use, generally, it directly sandblasts and removes rust on the surface of the steel pipe. Because there are many stubborn rust stains on the surface of the steel pipe, it is relatively difficult to directly remove the stubborn rust stains. Therefore, it is necessary to design a new type of rust removal device to solve the above problems. Summary of the Invention

[0030] Further, referring to Figure 3 and Figure 6 , the moving mechanism includes: an electric guide rail 11, a second sliding block 12, and a mounting plate 13; mounting grooves are provided between the inner walls of both sides at the top of the rust removal box 1, the electric guide rail 11 is fixedly installed in the mounting grooves; the second sliding block 12 is slidably installed at the bottom of the electric guide rail 11; the mounting plate 13 is fixedly connected to the bottom of the second sliding block 12.

[0031] Start the electric guide rail 11. The electric guide rail 11 drives the second sliding block 12 to slide in the installation groove, and the mounting plate 13 fixedly connected to the bottom of the second sliding block 12 also moves accordingly. The movement of the mounting plate 13 further drives the connected telescopic mechanism, pretreatment vibration mechanism and sandblasting mechanism to move horizontally in the rust removal box 1, so that the arc-shaped vibration plate 8 continuously vibrates the rust on the surface of the steel pipe, ensuring a comprehensive and effective pretreatment of the rust slag on the surface of the steel pipe, improving the rust removal effect. Through the automatic control of the electric guide rail 11, the operation is more convenient and efficient, reducing the error and labor intensity of manual adjustment, and being able to better realize the pretreatment of each part of the steel pipe.

[0032] Further, referring to Figure 1 , Figure 3 , Figure 6 and Figure 8 , the telescopic mechanism includes: an electric telescopic rod 14 and a buffer assembly. The electric telescopic rod 14 is fixedly connected to the middle position between the mounting plate 13 and the U-shaped groove plate 3. There are two groups of buffer assemblies, and the two groups of buffer assemblies are respectively fixedly installed on both sides between the U-shaped groove plate 3 and the mounting plate 13. The buffer assembly includes: an insertion sleeve 15, the insertion sleeve 15 is fixedly installed at the bottom of the mounting plate 13, an insertion rod 16 is inserted and adapted in the insertion sleeve 15, and the bottom of the insertion rod 16 is fixedly connected to the top outer wall of the U-shaped groove plate 3. A buffer spring 17 is fixedly connected between the inner wall of the top of the insertion sleeve 15 and the top of the insertion rod 16.

[0033] Start the electric telescopic rod 14. The electric telescopic rod 14 expands and contracts, driving the connected U-shaped groove plate 3 to move up and down. At the same time, the buffer assemblies on both sides of the electric telescopic rod 14 also work together. When the electric telescopic rod 14 extends or contracts, the insertion rod 16 moves relatively in the insertion sleeve 15, and the buffer spring 17 is compressed or stretched accordingly. In this process, the buffer assembly plays a role in stabilizing and buffering, ensuring the smooth movement of the U-shaped groove plate 3. The up and down movement of the U-shaped groove plate 3 further drives the pretreatment vibration mechanism to move up and down, enabling it to better contact the surface of the steel pipe for rust slag cracking operation, so as to adapt to steel pipes of different sizes and achieve the best rust removal effect.

[0034] Referring to Figures 1-2 , Figure 4 and Figure 6 , the sandblasting mechanism includes: a sandblasting head 18, the sandblasting head 18 is fixedly installed on the outer wall of the other side of the bottom of the U-shaped groove plate 3. One end of the sandblasting head 18 for sand inlet is connected with a sandblasting hose 20, and the end of the sandblasting hose 20 far from the sandblasting head 18 penetrates through the top of the rust removal box 1. The sandblasting hose 20 is externally connected to a sandblasting machine.

[0035] First, when sandblasting and rust removal are required for the steel pipe processed by the pre-treatment vibration mechanism, under the action of the sandblasting machine, sand grains flow through the sandblasting hose 20 to the sandblasting head 18. As the sand grains in the sandblasting hose 20 are continuously transported, the sandblasting head 18 sprays the high-speed sand grains onto the surface of the steel pipe. Since the pre-treatment vibration mechanism has cracked and loosened the rust slag on the surface of the steel pipe, the sand grains sprayed by the sandblasting head 18 at this time can more effectively impact the surface of the steel pipe, completely removing the rust and achieving efficient sandblasting and rust removal operation for the steel pipe.

[0036] Refer to Figures 1-4 and Figure 7 As shown in FIGS. and, the rotating assembly includes: a rotating motor 21, which is fixedly connected to the outer wall of the other side of the rust removal box 1. The rotating motor 21 is located below the pre-treatment vibration mechanism, and the output shaft of the rotating motor 21 penetrates through the other side of the rust removal box 1. The output shaft of the rotating motor 21 is fixedly connected with a first rotating base 22. A circular opening is provided on one side of the rust removal box 1. The clamping assembly includes a support plate 23. There are two support plates 23, and the two support plates 23 are respectively fixedly installed on the outer walls at both ends of one side of the rust removal box 1, and the two support plates 23 are symmetrically arranged at both ends of the circular opening. A sliding groove is provided on the side of each of the two support plates 23 close to each other and away from the circular opening. A sliding assembly is vertically installed in the sliding groove, and the same clamping plate 26 is fixedly installed between the sliding assemblies. The sliding assembly includes a second slide rail 24, which is vertically installed in the sliding groove. A third sliding block 25 is slidably connected to the second slide rail 24. The clamping plate 26 is fixedly installed between the two third sliding blocks 25. One side of the clamping plate 26 is provided with a threaded rod 27, and the threaded rod 27 is threadedly connected to the penetrating position on the clamping plate 26. One end of the threaded rod 27 close to the circular opening is rotatably connected to a second rotating base 28, and the first rotating base 22, the circular opening and the second rotating base 28 are all located at the same horizontal position. Conical frustums are fixedly installed at the ends of the first rotating base 22 and the second rotating base 28 close to each other.

[0037] First, insert one end of the steel pipe onto the rotating base 22 through the circular opening, so that the part of the steel pipe to be rust-removed is inside the rust removal box 1. Then, move the clamping plate 26 by sliding the third sliding block 25 on the second slide rail 24, that is, move the clamping plate 26 to the lowest position. After that, rotate the threaded rod 27 to push the second rotating base 28 closer to the steel pipe, and clamp and fix the steel pipe between the first rotating base 22 and the second rotating base 28. At this time, start the rotating motor 21, and its output shaft drives the first rotating base 22 to rotate. Since the steel pipe is clamped, the second rotating base 28 also rotates accordingly, so that the steel pipe can rotate stably, ensuring that all parts of the steel pipe can be evenly rust-removed, improving the quality of rust removal. The clamping assembly enables the device to adapt to steel pipes of different sizes and will not loosen or shift during the rotation of the steel pipe, ensuring the smooth progress of the rust removal operation.

[0038] Refer toFigure 1 , Figures 5-6 , a rust removal brush 29 is fixedly installed at the bottom of the U-shaped groove plate 3, and the rust removal brush 29 is located between the sand blasting head 18 and the support frame 8.

[0039] When rust removal treatment is carried out on mechanical parts and the pretreatment vibration mechanism vibrates and cracks the rust slag on the surface of the steel pipe, the rust removal brush 29 is always in contact with the surface of the steel pipe, and the moving mechanism drives the rust removal brush 29 to move horizontally repeatedly. At this time, the steel pipe rotates with the rotation of the clamping mechanism. Due to the rotation of the steel pipe, the rust removal brush 29 can comprehensively brush the surface of the steel pipe to further remove the remaining rust after pretreatment. In this process, the rust removal brush 29 cooperates with the pretreatment vibration mechanism and the sand blasting mechanism to carry out rust removal treatment on the steel pipe in different ways in turn, ensuring that the rust on the surface of the steel pipe is completely removed, providing a good foundation for subsequent processing and use.

[0040] Refer to Figures 1-4 , the central position of the inner wall of the bottom of the rust removal box 1 is set in a funnel shape, and a sand outlet is opened at the central position of the bottom of the rust removal box 1, and a sealing cover 30 is installed at the sand outlet.

[0041] When the sand blasting mechanism carries out rust removal operation on the steel pipe, some of the ejected sand grains will fall on the bottom of the rust removal box 1. When it is necessary to clean or maintain the rust removal box 1, first rotate the sealing cover 30 to gradually separate it from the external thread of the sand outlet until the sealing cover 30 completely opens the sand outlet. At this time, the sand grains accumulated at the bottom of the rust removal box can be smoothly discharged through the sand outlet. After the cleaning work is completed, align the sealing cover 30 with the sand outlet and rotate the sealing cover 30 to make it tightly combined with the external thread of the sand outlet to ensure that the rust removal box 1 is in a sealed state during subsequent rust removal operations, preventing sand grain leakage and external impurities from entering, so as to ensure the normal operation of the device and good rust removal effect.

[0042] Working principle: First, fix the steel pipe to be derusted inside the derusting box 1 through the clamping component of the clamping mechanism. Then, start the telescopic mechanism to drive the pretreatment vibration mechanism and the sandblasting mechanism to move up and down inside the derusting box 1. Move up and down to an appropriate height to adapt to the size of the steel pipe to achieve the best derusting effect. Start the moving mechanism to drive the pretreatment vibration mechanism and the sandblasting mechanism to move horizontally left and right repeatedly inside the derusting box 1. When the roller 10 rolls on the guide rail plate 4, since the bottom of the guide rail plate 4 is wavy, during the process of the roller 10 rolling from the highest position at the bottom of the guide rail plate 4 to the lowest position, it will drive the support frame 8 to move downward through the elastic sliding component. At this time, the protrusions at the bottom of the arc-shaped vibration plate 9 contact the steel pipe, and the rust slag on the surface of the steel pipe is vibrated and cracked. When the roller 10 rolls from the lowest position at the bottom of the guide rail plate 4 to the highest position, under the action of the elastic sliding component, the support frame 8 moves upward, and the arc-shaped vibration plate 9 is separated from the steel pipe. In this way, the rust slag on the surface of the steel pipe is vibrated and pretreated repeatedly. At the same time, the sandblasting mechanism located in the U-shaped groove plate 3 and the moving mechanism are started simultaneously. The sandblasting mechanism performs sandblasting derusting on the rust that has become loose after pretreatment. During the whole process, the rotating component of the clamping mechanism drives the clamping component and the steel pipe to rotate to ensure that the steel pipe is derusted in all directions. The pretreatment vibration mechanism cooperates with the unique roller 10 and the wavy guide rail plate 4 to efficiently vibrate and crack the rust slag on the surface of the steel pipe, making the rust loose and improving the overall derusting effect. The cooperation of the telescopic mechanism and the moving mechanism can flexibly move the positions and heights of the pretreatment vibration mechanism and the sandblasting mechanism to adapt to steel pipes of different sizes, improving the versatility of the device. Secondly, the sandblasting mechanism performs sandblasting derusting on mechanical parts after pretreatment, which can completely remove the loose rust and ensure the derusting effect.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
