Description

Technical Field

[0001] This invention relates to the field of corrosion resistance testing technology, specifically to a corrosion resistance testing instrument and method for metal material coatings. Background Technology

[0002] The corrosion resistance of metallic materials refers to their ability to resist corrosion by a medium. It is determined by their composition, chemical properties, and microstructure. During the production of finished products, corrosion resistance testing is required.

[0003] For example, patent CN221707252U discloses a metal parts corrosion resistance testing device, which includes a testing cylinder body. A rotating ring is fixedly connected to the top of the testing cylinder body, and a fixed frame is fixedly connected to the top of the rotating ring. A cleaning component is rotatably connected inside the rotating ring. The cleaning component is used to clean the metal parts before corrosion resistance testing. A drive wheel is rotatably connected to the fixed frame, and a lifting component is fixedly connected to one end of the drive wheel. The lifting component is used to improve the testing effect. A valve is opened on one side of the bottom of the testing cylinder body. The cleaning component cleans the metal parts before corrosion resistance testing to ensure that the metal surface is free of impurities and corrosion products, thereby improving the accuracy and reliability of the test. Secondly, the application of the lifting component can effectively improve the testing effect, making the test results more comprehensive and accurate.

[0004] For example, patent CN212964544U discloses a device for detecting the corrosion resistance of steel wire coating, which includes a base. A foot pad is fixedly installed on the lower outer surface of the base. Columns are fixedly installed on both sides of the upper end of the base. A crossbeam is fixedly installed on the upper end of the column. A cylinder is fixedly installed in the middle of the upper end of the crossbeam. A movable plate is fixedly connected to the lower end of the cylinder below the crossbeam. A clamp is fixedly installed on the lower outer surface of the movable plate. A liquid storage tank is placed in the middle of the upper end of the base. A timer is fixedly installed on the upper side of one side of the liquid storage tank. A pH detector is fixedly installed on the upper side of the other side of the liquid storage tank. A probe is fixedly installed at one end of the pH detector on the inner wall of the liquid storage tank. A connecting seat is sleeved on the upper end of the foot pad.

[0005] For example, a coating corrosion resistance testing device disclosed in patent CN210198929U includes a workbench. Support legs are fixedly installed on the lower surface of the workbench near both sides, and a testing platform is fixedly installed on the upper surface of the workbench near the middle. The testing platform has a placement groove inside, and an adjustment device is connected to the inner side of the testing platform. The adjustment device consists of a threaded rod, a handle, an adjustment plate, and a connector. A mounting base is fixedly installed on the upper surface of the workbench near the outer side of the testing platform. A sealing cover is connected to the top of the mounting base. A connecting pipe is connected through the top of the sealing cover. A funnel is connected to the top of the connecting pipe, and a guide device is connected between the connecting pipe and the sealing cover.

[0006] Most of the existing technologies mentioned above improve the overall structure. However, existing corrosion resistance testing instruments for metal coatings are limited in use because metal coatings are mostly multi-layered composite coatings. During the testing process, it is necessary to test the corrosion resistance of different layers. They cannot simultaneously test the corrosion resistance of multiple types of coatings, thus requiring the preparation of different testing reagents for multiple tests, which has certain limitations. Summary of the Invention

[0007] The purpose of this invention is to provide a corrosion resistance testing instrument and method for metal material coatings, in order to solve the problem mentioned in the background art that since most metal material coatings are multi-layer composite coatings, the corrosion resistance of different layers needs to be tested during the testing process, and it is impossible to simultaneously test the corrosion resistance of multiple types of coatings, thus requiring the preparation of different testing reagents for multiple testing operations.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a corrosion resistance tester and method for metal material coatings, comprising a reserved base, a movable support frame nested and connected to the outer side of the reserved base, and a storage container nested and installed on the outer side of the movable support frame, wherein the storage container stores the test liquid; a reserved electric push rod is provided at the lower end of the reserved base, and a guide movable rack is connected to the output end of the reserved electric push rod, and the guide movable rack is nested and connected to the inner end of the reserved base; an adaptive guide structure is provided between the movable support frame and the reserved base, and the movement range of the storage container is controlled by the adaptive guide structure.

[0009] Furthermore, the adaptive guide structure is provided with a docking movable disk, which is fixedly docked to the outside of the movable support frame. An internal toothed block is rotatably connected to the outside of the docking movable disk, and a first spring is fixedly connected to the outside of the internal toothed block. The first spring docks with the inside of the docking movable disk, while the internal toothed block meshes with the outside of the guide movable rack.

[0010] Furthermore, the reserved electric push rod pushes the guide rack to form a sliding structure along the inner side of the reserved base, and during the leftward movement of the guide rack, it drives the contacting docking disk to rotate synchronously. When the guide rack returns to its rightward reset position, it is in a non-meshing state with the built-in tooth block on the outer side of the docking disk.

[0011] Furthermore, when the outer toothed block of the guide rack contacts the inner toothed block on the outer side of the docking movable disk, the docking movable disk rotates 90 degrees, and the docking movable disk forms an elastic docking structure with the inner toothed block through the first spring.

[0012] Furthermore, the inner side of the reserved base is provided with a guide support structure, which adaptively adjusts the support height of the storage container; the guide support structure is provided with an abutting docking member, which is nested and docked at the lower end of the reserved base; a vertical movable member is connected through the inner side of the reserved base, and a second spring is fixedly connected to the outer side of the vertical movable member, and the second spring is docked with the upper end face of the reserved base.

[0013] Furthermore, the reserved base has a built-in first liquid bladder bonded internally, and the outer side of the built-in first liquid bladder is connected to a transverse movable top block, and the transverse movable top block corresponds to the outer side of the guide movable rack. The inner side of the built-in first liquid bladder is connected to a supply hose, and the supply hose runs along the inner side of the reserved base. The outer end of the reserved base is nested with a transverse limiting component, and the lower end of the transverse limiting component is connected to a built-in second liquid bladder, and the built-in second liquid bladder is connected to the end of the supply hose.

[0014] Furthermore, when the guide rack moves to contact the vertical movable component via the reserved electric push rod, the vertical movable component is stretched by the second spring and moves along the upper end face of the reserved base. The vertical movable component also applies pressure upward to the contacted storage container, and the storage container forms a sliding structure along the outer side of the movable support frame.

[0015] Furthermore, when the guide rack moves to contact the transverse movable top block, the transverse movable top block applies pressure inward to the built-in first liquid bladder, and the built-in first liquid bladder forms a supply state with the built-in second liquid bladder through the supply hose, and the transversely expanded built-in second liquid bladder pushes the transverse limiting component to move outward.

[0016] A corrosion resistance testing instrument for metal material coatings is disclosed, along with a testing method for the corrosion resistance testing instrument, comprising the following steps:

[0017] S1: The pre-installed electric push rod drives the guide rack to move laterally. The leftward movement of the guide rack will cause the docking disc and the movable support frame to rotate synchronously through the built-in toothed blocks until the outer toothed blocks of the guide rack are fully in lateral contact with the docking disc. This will cause the movable support frame and the corresponding storage container to adaptively adjust their angles, enabling rapid testing and treatment of the corrosion resistance of different coatings.

[0018] S2: When the guide rack contacts the vertical moving part, the vertical moving part under force causes the upward-moving vertical moving part to simultaneously apply pressure to the storage container in contact with the corresponding position. The storage container under force will move vertically along the outside of the corresponding movable support frame and react with the work to be tested in contact.

[0019] S3: When the guide rack contacts the transverse movable top block, pressure will be applied to the built-in first liquid bladder, allowing the built-in first liquid bladder to supply laterally through the supply hose and the built-in second liquid bladder. The transversely expanding built-in second liquid bladder pushes the transverse limiting component outward, thereby providing auxiliary support to the outside of the storage container at the corresponding contact position through the transverse limiting component, ensuring its support strength and detection accuracy.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This corrosion resistance testing instrument and method for metal coatings features an adaptive guiding structure. This structure controls the movement range of the storage container. After placing the workpiece in the corresponding position, a pre-installed electric push rod drives the guide rack to move laterally. The leftward-moving guide rack, through its built-in toothed blocks, drives the docking disc and the movable support frame to rotate synchronously until the outer toothed blocks of the guide rack are fully in lateral contact with the docking disc. This causes the movable support frame to adaptively adjust its angle with the storage container at the corresponding angle. By using different types of testing liquids during the testing process, the corrosion resistance of different coatings can be quickly tested. This allows for simultaneous and rapid testing of multiple types of coating corrosion resistance without the need for repeated mixing of different testing reagents, thus improving the device's practicality.

[0022] Furthermore, during the continuous lateral movement of the guide rack, when its outer side contacts the vertical moving part, the force-bearing vertical moving part will be forced to move along the upper end face of the reserved base by the second spring. This allows the upward-moving vertical moving part to simultaneously apply pressure to the storage container in contact with the corresponding position. The force-bearing storage container will then move vertically along the outer side of the corresponding movable support frame, thereby adaptively reacting to the contacting work to be tested, allowing the user to quickly test the corrosion resistance of the corresponding coating.

[0023] Furthermore, a guide support structure is provided, which adaptively adjusts the support height of the storage container. As the guide rack moves outward continuously, it applies pressure when it contacts the lateral movable top block, causing it to move along the interior of the reserved base. This pressures the built-in first liquid bladder, which then supplies liquid laterally to the built-in second liquid bladder via a supply hose. The laterally expanding second liquid bladder pushes the lateral limiting component outward, thereby providing auxiliary support to the outer side of the storage container at the corresponding contact position through the lateral limiting component. This prevents instability during vertical movement and ensures support strength and detection accuracy. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-9This invention provides the following technical solution: a corrosion resistance tester and method for metal material coatings. To address the problem that since most metal material coatings are multi-layered composite coatings, the corrosion resistance of different layers needs to be tested during the testing process, making it impossible to simultaneously test the corrosion resistance of multiple types of coatings, thus requiring the preparation of different testing reagents for multiple tests, the invention discloses a method comprising: a pre-reserved base 1 with a movable support frame 16 nested on its outer side; a storage container 2 nested on the outer side of the movable support frame 16, with the storage container 2 storing the test liquid; a pre-reserved electric push rod 3 provided at the lower end of the pre-reserved base 1, with the output end of the pre-reserved electric push rod 3 connected to a guide rack 4, which is nested within the inner end of the pre-reserved base 1; and an adaptive guiding structure provided between the movable support frame 16 and the pre-reserved base 1, which controls the range of motion of the storage container 2.

[0036] The adaptive guiding structure is equipped with a docking movable disk 5, which is fixedly docked to the outside of the movable support frame 16. An internal toothed block 6 is rotatably connected to the outside of the docking movable disk 5, and a first spring 7 is fixedly connected to the outside of the internal toothed block 6. The first spring 7 engages with the inside of the docking movable disk 5. Simultaneously, the internal toothed block 6 meshes with the outside of the guide movable rack 4. A pre-installed electric push rod 3 pushes the guide movable rack 4 to form a sliding structure along the inside of the pre-installed base 1. During the leftward movement of the guide movable rack 4, the docking movable disk 5 in contact rotates synchronously. 4. When the guide rack 4 moves to the right and resets, it is in a non-meshing state with the inner toothed block 6 on the outer side of the docking movable disk 5. When the outer toothed block of the guide rack 4 contacts the inner toothed block 6 on the outer side of the docking movable disk 5, the docking movable disk 5 rotates 90 degrees. The docking movable disk 5 forms an elastic docking structure with the inner toothed block 6 through the first spring 7. After the workpiece to be tested is placed in the corresponding position, the reserved electric push rod 3 can be driven to push the guide rack 4 to perform lateral displacement. The guide rack 4 moving to the left will drive the docking movable disk 5 and the movable support frame 16 to rotate synchronously through the inner toothed block 6 until the guide rack moves to the left. The outer teeth of the moving rack 4 are fully in lateral contact with the docking movable disk 5, causing the movable support frame 16 to adaptively adjust the angle of the storage container 2 at the corresponding angle. This allows for rapid testing of the corrosion resistance of different coatings using different types of testing liquids. [Subsequently, the guide rack 4 is reset to the right via the reserved electric push rod 3, and it is in a non-meshing state with the built-in teeth 6 on the outer side of the docking movable disk 5, thus avoiding deviation in the support position of the storage container 2 after the angle adjustment.] This enables simultaneous and rapid testing of the corrosion resistance of multiple coating types without the need for reverse... By repeatedly mixing different test reagents and conducting multiple tests, the guide rack 4, during its continuous lateral movement, comes into contact with the vertical moving part 9. The force-bearing vertical moving part 9 will then be stressed by the second spring 10, which moves along the upper surface of the reserved base 1. This allows the upward-moving vertical moving part 9 to simultaneously apply pressure to the corresponding contact storage container 2. The stressed storage container 2 will then move vertically along the outer side of the corresponding movable support frame 16, thus adaptively reacting with the contacting work to be tested, allowing the user to quickly test the corrosion resistance of the corresponding coating.

[0037] Example 2: Based on Example 1, a guide support structure is also disclosed, the specific structure of which is as follows:

[0038] A guide support structure is provided on the inner side of the reserved base 1, which adaptively adjusts the support height of the storage container 2.

[0039] The guide support structure is equipped with abutting connector 8, which is nested and connected to the lower end of the reserved base 1. A vertical movable member 9 is connected through the inner side of the reserved base 1, and a second spring 10 is fixedly connected to the outer side of the vertical movable member 9. The second spring 10 is connected to the upper end face of the reserved base 1. An internal first liquid bladder 12 is bonded to the inside of the reserved base 1, and a transverse movable top block 11 is connected to the outer side of the internal first liquid bladder 12. The transverse movable top block 11 is aligned with the outer side of the guide movable rack 4. The inner side of the built-in first liquid bladder 12 is connected to a supply hose 15, which runs along the inner side of the reserved base 1. A lateral limiting component 14 is nested at the outer end of the reserved base 1, and the lower end of the lateral limiting component 14 is connected to the built-in second liquid bladder 13. The built-in second liquid bladder 13 and the end of the supply hose 15 are connected to each other. When the guide movable rack 4 moves to contact the vertical movable member 9 through the reserved electric push rod 3, the vertical movable member 9 is stretched by force to stretch the second spring 10 along the upper surface of the reserved base 1. The vertical movable component 9 applies pressure upwards to the contacting storage container 2, and the storage container 2 forms a sliding structure along the outside of the movable support frame 16. When the guide movable rack 4 moves to contact the horizontal movable top block 11, the horizontal movable top block 11 applies pressure inwards to the built-in first liquid bladder 12, and the built-in first liquid bladder 12 forms a supply state with the built-in second liquid bladder 13 through the supply hose 15. The horizontally expanded built-in second liquid bladder 13 pushes the horizontal limiting component 14 to move outwards. During the continuous outward movement of the guide movable rack 4, when it contacts the horizontal movable top block 11, it will apply pressure accordingly, allowing it to move along the interior of the reserved base 1, thereby applying pressure to the built-in first liquid bladder 12, allowing the built-in first liquid bladder 12 to provide horizontal supply through the supply hose 15 and the built-in second liquid bladder 13. The horizontally expanded built-in second liquid bladder 13 pushes the horizontal limiting component 14 to move outwards, thereby providing auxiliary support to the outside of the storage container 2 at the corresponding contact position through the horizontal limiting component 14, preventing instability during its vertical movement.

[0040] Example 3: Based on Examples 1 and 2, a detection method for a corrosion resistance tester is also disclosed, including the following steps:

[0041] S1: The pre-installed electric push rod 3 drives the guide rack 4 to move laterally. The guide rack 4, moving to the left, will drive the docking disk 5 and the movable support frame 16 to rotate synchronously through the built-in tooth block 6 until the outer tooth block of the guide rack 4 is fully in lateral contact with the docking disk 5. This will cause the movable support frame 16 to adaptively adjust its angle with the storage container 2 at the corresponding angle, allowing for rapid testing and treatment of the corrosion resistance of different coatings.

[0042] S2: When the guide rack 4 contacts the vertical movable member 9, the vertical movable member 9, which is in an upward state, applies pressure to the storage container 2 at the corresponding contact position. The storage container 2, which is under pressure, will move vertically along the outside of the corresponding movable support frame 16 and react with the work to be tested.

[0043] S3: When the guide rack 4 contacts the transverse movable top block 11, pressure will be applied to the built-in first liquid bladder 12, so that the built-in first liquid bladder 12 is supplied laterally through the supply hose 15 and the built-in second liquid bladder 13. The transversely expanded built-in second liquid bladder 13 pushes the transverse limiting component 14 outward, thereby providing auxiliary support to the outside of the storage container 2 at the corresponding contact position through the transverse limiting component 14, ensuring its support strength and detection accuracy.
