Description

Technical Field

[0001] This utility model belongs to the field of clamping technology, and in particular relates to a corrosion-resistant and wear-resistant metal clamp. Background Technology

[0002] Metal clips play a crucial role in numerous industrial production processes and the manufacture of everyday consumer goods, and are widely used in the connection and fixation of various components. Traditional metal clips are mostly made of a single metal material, or undergo only simple surface treatment to meet basic mechanical performance requirements.

[0003] However, traditional metal clips have many drawbacks. From a material perspective, clips made of a single metal material are prone to corrosion in complex and changing environments, such as humid or acidic / alkaline environments, which can damage the clip's structure and affect its normal use and service life. Even clips with simple surface treatments still have limited corrosion resistance and wear resistance. With friction, collisions, and environmental factors during use, the surface treatment layer is prone to peeling off, thus losing its protective effect. From a structural perspective, traditional clips lack scientific and reasonable positioning and avoidance designs. When assembled with other components, inaccurate installation often occurs, and interference with surrounding components is likely to occur. This not only affects the stability of the entire system but may also lead to damage to the clips or other components.

[0004] To address these issues, we provide a corrosion-resistant and wear-resistant metal clip. Utility Model Content

[0005] The purpose of this utility model is to provide a corrosion-resistant and wear-resistant metal clip. By combining the clearance groove, the first positioning groove, the second positioning groove, the base layer, the intermediate layer and the outer layer, the problem of poor corrosion resistance and wear resistance of metal clips in the prior art, as well as easy interference with surrounding components, is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a corrosion-resistant and wear-resistant metal clip, comprising a metal clip body, an avoidance groove on one side of the metal clip body, a first positioning groove on the other side of the metal clip body, and a second positioning groove on the inner wall of the metal clip body; the metal clip body includes a base layer, an intermediate layer fixedly connected to the outer surface of the base layer, and an outer layer fixedly connected to the outer surface of the intermediate layer; the intermediate layer includes a metal underlayer, a corrosion-resistant barrier layer, a transition bonding layer, and a reinforcing layer. The setting of the first positioning groove, the second positioning groove, and the avoidance groove greatly improves the adaptability and installation accuracy of the clip in practical applications, ensuring that it fits tightly and accurately with other components. The material system composed of the base layer, the intermediate layer, and the outer layer fundamentally enhances the corrosion resistance and wear resistance of the clip. The stainless steel base layer provides solid foundation strength, the coatings of the intermediate layer successively strengthen the bonding force, corrosion resistance, and wear resistance, and the outer layer further consolidates the protective effect, comprehensively improving the performance of the clip. Compared with traditional clips, it can better adapt to complex and harsh working environments.

[0008] The present invention is further configured such that the metal underlayer is coated on the outer surface of the base layer, the corrosion-resistant barrier layer is coated on the outer surface of the metal underlayer, the transition bonding layer is coated on the outer surface of the corrosion-resistant barrier layer, and the reinforcing layer is coated on the outer surface of the transition bonding layer.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model significantly improves the assembly efficiency and accuracy of the clips and other components by rationally arranging the avoidance grooves and positioning grooves. It solves the problems of inconvenient installation and easy interference of traditional clips. From the base layer to the middle layer and then to the outer layer, each layer of material performs its own function and works together to comprehensively improve the corrosion resistance and wear resistance of the clips.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-5This utility model is a corrosion-resistant and wear-resistant metal clip, including a metal clip body 1, an avoidance groove 2 on one side of the metal clip body 1, a first positioning groove 3 on the other side of the metal clip body 1, and a second positioning groove 4 on the inner wall of the metal clip body 1; the metal clip body 1 includes a base layer 11, an intermediate layer 12 fixedly connected to the outer surface of the base layer 11, and an outer layer 13 fixedly connected to the outer surface of the intermediate layer 12; the intermediate layer 12 includes a metal base layer 121, a corrosion-resistant barrier layer 122, a transition bonding layer 123, and a reinforcing layer 124.

[0026] Specifically, the design of the first positioning groove 3, the second positioning groove 4, and the clearance groove 2 greatly improves the adaptability and installation accuracy of the clip in practical applications, ensuring that it fits tightly and accurately with other components. The material system consisting of the base layer 11, the intermediate layer 12, and the outer layer 13 fundamentally enhances the corrosion resistance and wear resistance of the clip. The stainless steel base layer 11 provides solid foundation strength, the coatings of the intermediate layer 12 successively strengthen the bonding force, corrosion resistance, and wear resistance, and the outer layer 13 further consolidates the protective effect, comprehensively improving the performance of the clip. Compared with traditional clips, it can better adapt to complex and harsh working environments.

[0027] A metal underlayer 121 is coated on the outer surface of the base layer 11, a corrosion-resistant barrier layer 122 is coated on the outer surface of the metal underlayer 121, a transition bonding layer 123 is coated on the outer surface of the corrosion-resistant barrier layer 122, and a reinforcing layer 124 is coated on the outer surface of the transition bonding layer 123. The outer layer 13 includes a first anti-corrosion and wear-resistant layer 131 and a second anti-corrosion and wear-resistant layer 132. The first anti-corrosion and wear-resistant layer 131 is coated on the outer surface of the second anti-corrosion and wear-resistant layer 132. The metal underlayer 121 is made of nickel alloy, the corrosion-resistant barrier layer 122 is made of amorphous alloy coating, the transition bonding layer 123 is made of cobalt-chromium-aluminum-yttrium alloy layer, the reinforcing layer 124 is made of chromium carbide-nickel-chromium cermet coating, the first anti-corrosion and wear-resistant layer 131 is made of polytetrafluoroethylene composite coating, the second anti-corrosion and wear-resistant layer 132 is made of silica-based sealing coating, the base layer 11 is made of stainless steel, and the edges of the metal clip body 1 are rounded.

[0028] Specifically: the metal underlayer 121 first enhances the bond between the base layer 11 and the subsequent coating, laying a solid foundation for the stability of the entire intermediate layer 12; the corrosion-resistant barrier layer 122 follows closely behind, blocking the intrusion of corrosive media; the transition bonding layer 123 further strengthens the connection between the coatings; the reinforcing layer 124 ultimately improves the wear resistance. All layers work together to significantly improve the overall performance of the clip. The combination of the first anti-corrosion and wear-resistant layer 131 and the second anti-corrosion and wear-resistant layer 132 forms a dual protection mechanism. The second anti-corrosion and wear-resistant layer 132 provides sealing and protection, while the first anti-corrosion and wear-resistant layer 131 further enhances the anti-corrosion and wear-resistant effect, making the outer layer 13 of the clip more comprehensive and effectively resisting external erosion. The nickel alloy, as the metal underlayer 121, with its excellent adhesion properties, can firmly connect the base layer 11 and the subsequent coating; the amorphous alloy coating... The corrosion-resistant barrier layer 122 possesses excellent corrosion resistance, and together with the other layer, it provides strong support for the anti-corrosion performance of the clip. The cobalt-chromium-aluminum-yttrium alloy layer serves as a transition bonding layer 123, effectively enhancing the bonding strength between the various coatings and ensuring the stability of the coating structure. The chromium carbide-nickel-chromium cermet coating serves as a reinforcing layer 124, giving the clip excellent wear resistance, enabling it to maintain good working condition even in environments with frequent friction. The combination of the polytetrafluoroethylene composite coating and the silica-based sealing coating gives the outer layer 13 both good anti-corrosion and wear resistance, providing reliable external protection for the clip. The base layer 11 is made of stainless steel, making full use of its strength and toughness advantages to provide a stable foundation for the clip. The rounded corners of the metal clip body 1 effectively avoid stress concentration and prevent the clip from cracking or being damaged due to stress concentration.

[0029] The working principle of this utility model is as follows: The metal clip body 1, by opening an avoidance groove 2 on one side, can effectively avoid spatial interference that may occur during the installation or use of other components, ensuring smooth cooperation between the clip and other parts. The first positioning groove 3 on the other side provides a basis for the precise positioning of the clip with other components in a specific direction, which helps to ensure accurate installation. The second positioning groove 4 on the inner wall can achieve positioning connection with the internally cooperating components, ensuring the stability and accuracy of the clip during operation. The metal clip body 1 is composed of a base layer 11, an intermediate layer 12, and an outer layer 13. The base layer 11 is made of stainless steel, which has good strength and toughness, providing basic support for the clip. The metal underlayer 121 of the intermediate layer 12 is coated on the outer surface of the base layer 11 and is made of nickel alloy. It can enhance the adhesion between the base layer 11 and the subsequent coating, making the entire coating structure more stable. Next, a corrosion-resistant barrier layer 122 is coated on the outside of the metal base layer 121. The amorphous alloy coating effectively blocks external corrosive media from eroding the base layer 11. A transition bonding layer 123 is coated on the outside of the corrosion-resistant barrier layer 122. A cobalt-chromium-aluminum-yttrium alloy layer further strengthens the bonding force between the coatings. A reinforcing layer 124 is coated on the outside of the transition bonding layer 123. A chromium carbide-nickel-chromium cermet coating can significantly improve the wear resistance of the clip. In the outer layer 13, a silica-based sealing coating serves as the second anti-corrosion and wear-resistant layer 132, providing a sealing and protective function to prevent the penetration of external substances. A polytetrafluoroethylene composite coating serves as the first anti-corrosion and wear-resistant layer 131, further enhancing the anti-corrosion and wear resistance of the clip. The edges of the metal clip body 1 are rounded to reduce stress concentration, prevent damage to the clip due to stress concentration, and extend its service life.
