Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of forging casting, more specifically to a rust-proof and wear-resistant forging. Background Art
[0002] The workpiece obtained by forging a metal blank by physical means to deform it is called a forging. This forging is generally used in major fields such as petroleum, chemical industry or automobile. The forging method is divided into cold forging, warm forging and hot forging, which is divided according to the temperature during forging. Forging at room temperature is called cold forging, and forging at a temperature higher than that of the metal blank is called hot forging. In actual use, the forging is directly placed in the air. After long-term use, it is easy to rust, corrode and wear after being exposed to wind, sun and rain. Especially some rotating forgings are more prone to wear due to the lack of continuous lubrication, and the service life is greatly shortened, which has become a problem that many companies urgently need to solve. In view of this, the inventor proposes a rust-proof and wear-resistant forging, which achieves the effect of rust and corrosion resistance by passivating the forging and spraying an anti-rust coating, and continuously lubricates the easily worn areas to avoid wear.
[0003] In order to solve the problem that rust and corrosion easily occur during the use of forgings and extend the service life, a Chinese patent (authorization announcement number: CN215763796U) discloses a high-strength and anti-corrosion I-shaped flange forging. The utility model includes a flange mechanism, which includes a pipe body and flanges connected to both ends of the pipe body. The inner diameter and outer diameter of the pipe body are gradually reduced from the middle to the two ends; and the pipe wall of the pipe body is an arc wall, and the inner surface of the pipe body is fixed with a plurality of spiral guide plates evenly spaced along the circumference of the pipe body; the two ends of the spiral guide plates extend to the two ends of the pipe body respectively; the center of the flange is provided with a through hole connected to the pipe body; the inner wall of the pipe body is coated with an anti-corrosion coating; a plurality of reinforcement mechanisms are evenly distributed on the outside of the pipe body in the circumferential direction; each reinforcement mechanism includes a support plate and two support plates respectively located at both ends of the support plate; the support plate and the support plate are fixedly connected; the middle part of the support plate close to the pipe body is against the outer surface of the pipe body; the two support plates correspond to two flanges respectively; each support plate is close to the outer peripheral wall of the corresponding flange and fixedly connected to the flange. The utility model provides anti-corrosion performance through the anti-corrosion coating on the inner surface of the pipe body, thereby extending the service life.
[0004] This solution still has some shortcomings in application. Since forgings are usually easily exposed to the air, the anti-corrosion coating will fall off as it constantly reacts with the air, thus affecting its service life. At the same time, forgings often rotate and wear each other during use, especially when there is no lubrication between the two. The wear will be faster, which also affects the service life. Therefore, it is necessary to improve the structure of the forgings to make them have better anti-rust, corrosion resistance and wear resistance. Utility Model Content

[0020] The specific implementation of the present utility model will be further described below with reference to the accompanying drawings.
[0021] like Figures 1 to 4 As shown, a rust-proof and wear-resistant forging comprises an upper forging 1 and a lower forging 2. The surfaces of the upper forging 1 and the lower forging 2 are passivated to form an anti-oxidation film 3, and the outer surface of the anti-oxidation film 3 is coated with an anti-rust coating 4. A circular convex cavity 21 is provided in the middle of the lower forging 2, and an outer wall of the circular convex cavity 21 is provided with an external thread 22 and a telescopic block 23 is provided on the symmetrical side. A covering groove 5 is correspondingly provided in the middle of the upper forging 1, and an internal thread 51 is built in the side edge 5 of the covering groove, and the internal thread 51 is adapted to be screwed with the external thread 22. A circular circumferential edge 6 is provided on the outer side of the lower forging 2, and a rotation groove 7 is formed between the circular circumferential edge 6 and the circular convex cavity 21, and the upper forging 1 is embedded in the rotation groove 7 and can rotate along the rotation groove 7.
[0022] Furthermore, the external thread 22 and the internal thread 51 are parallel threads, and the telescopic block 23 is embedded between the internal threads 51 .
[0023] Furthermore, a protruding block 8 is provided on the side wall of the internal thread 51 , and the protruding block 8 is movably abutted against the telescopic block 23 .
[0024] Furthermore, an opening 9 is provided at the top of the circular raised cavity 21 , and a through hole is correspondingly provided at the top of the upper forging 1 , and the through hole is arranged corresponding to the opening 9 .
[0025] Furthermore, a telescopic cavity 10 is provided on the symmetrical side of the circular raised cavity 21, a spring 11 is provided at the bottom of the telescopic cavity 10, the telescopic block 23 is embedded in the telescopic cavity 10 and the bottom is connected to the spring 11, and the telescopic block 23 can be telescoped along the telescopic cavity 10 through the spring 11.
[0026] Furthermore, a mesh-like perforation (not marked in the schematic diagram due to viewing angle reasons) is provided between the telescopic cavity 10 and the circular convex cavity 21 , and the telescopic cavity 10 and the circular convex cavity 21 are connected.
[0027] Furthermore, the rotating groove 7 is in an oblique structure that gradually decreases from the inside to the outside.
[0028] [Example]
[0029] First, the upper forging 1 and the lower forging 2 are rotationally connected through the external thread 22 and the internal thread 51 (the internal thread and the external thread are parallel threads, not spiral threads), and the lubricating oil is poured into the circular convex cavity 21 of the lower forging 2 through the perforation of the upper forging 1, and the lubricating oil is stored in the circular convex cavity 21. Then, since the surfaces of the upper forging 1 and the lower forging 2 are provided with an anti-oxidation film 3 and the outer sides of the anti-oxidation film are coated with an anti-rust coating 4, they can effectively prevent rust and oxidation during use. Then, when the upper forging 1 and the lower forging 2 rotate, when the telescopic block 23 abuts against the convex block 8, the telescopic block 23 penetrates into the telescopic cavity 10 inwardly, so that the lubricating oil in the telescopic cavity 10 flows out to the rotating groove 7. Since the rotating groove 7 is an oblique structure that gradually decreases from the inside to the outside, the lubricating oil can flow down to lubricate the entire rotating groove 7 to prevent wear. Finally, after the lubricating oil in the circular convex cavity 21 is used up, it can be continued to be added through the perforation to keep the rotating groove 7 lubricated.
[0030] It can be seen from the above description of the utility model that, compared with the prior art, the advantages of the utility model are:
[0031] The utility model first forms an anti-oxidation film through passivation treatment of the upper forging and the lower forging, and sprays an anti-rust coating on the outer side of the anti-oxidation film. Through this setting, the upper forging and the lower forging have the functions of rust and corrosion resistance, and significantly improve the corrosion resistance of the forging; then, the upper forging and the lower forging are connected by threaded rotation, and the circular convex cavity in the middle of the lower forging is provided with a telescopic cavity, and the telescopic block in the telescopic cavity can be extended inward through the abutment of the convex block of the upper forging, so that the lubricating oil in the circular convex cavity flows to the rotating groove. Since the abutment of the convex block and the telescopic block is cyclic, the continuous circulation of the lubricating oil can be guaranteed, the lubrication of the rotating groove is maintained, and the wear caused by the continuous rotation of the upper forging and the lower forging is avoided; finally, the lubricating oil can be regularly injected into the circular convex cavity through the perforation of the upper forging to maintain the normal use of the lubricating oil. The utility model has a novel structure and a clever design, can realize the anti-rust, anti-corrosion and anti-wear functions of the forging, and is suitable for promotion.
[0032] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial improvement of the utility model using this concept should be regarded as an infringement of the protection scope of the utility model.
