Description

Technical Field

[0001] This utility model relates to the field of material surface treatment and testing technology, and in particular to a metal surface coating wear resistance testing device. Background Technology

[0002] Metal materials are widely used in industrial manufacturing, but due to their susceptibility to corrosion and wear, they often require a protective or decorative coating. These coatings not only improve the aesthetics of metal products but also enhance their corrosion resistance, oxidation resistance, and wear resistance, thereby extending their service life. Wear resistance is a crucial indicator of coating quality, especially under high-friction, high-temperature, or heavy-load conditions, where the coating's wear resistance directly affects the product's safety and stability. Therefore, during the metal coating production process, specialized wear resistance testing equipment is typically used to quantitatively evaluate the coating's wear resistance to ensure it meets practical application requirements.

[0003] Most commercially available metal surface coating wear resistance testing devices are based on fixed friction heads and testing principles under single environmental conditions. While these devices can perform basic wear resistance testing, they still have many shortcomings in practical applications. For example, most devices lack temperature control functions and cannot simulate usage scenarios under different ambient temperatures, making it difficult for test results to accurately reflect the actual performance of the coating under complex working conditions. Furthermore, some testing devices have simple temperature control systems with limited adjustment ranges, making it difficult to achieve rapid heating and cooling, and also failing to guarantee temperature uniformity and stability during testing. These limitations make traditional wear resistance testing equipment poorly adaptable to diverse product testing needs, affecting the accuracy and comparability of test data.

[0004] Therefore, it is necessary to design a metal surface coating wear resistance testing device to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing metal coating wear resistance testing devices, which usually lack temperature control functions and cannot simulate usage scenarios under different ambient temperatures, resulting in test results that are difficult to truly reflect the actual performance of the coating under complex working conditions, this utility model provides a metal surface coating wear resistance testing device.

[0006] The technical solution is as follows: A metal surface coating wear resistance testing device includes a box, a placement platform, a sliding plate, an electric push rod, a connecting frame, a wear testing component, and a temperature control component. The placement platform is fixedly connected to the top of the box, and sliding plates are symmetrically arranged on the left and right sides of the front of the box. An electric push rod with downward output is installed at the top of the box, and the output end of the electric push rod is fixedly connected to the connecting frame. The wear testing component is set at the bottom of the connecting frame, and the temperature control component is set at the connection between the rear side and the top of the box.

[0007] As an improvement to the above solution, the temperature control component includes a temperature controller, a circulation pipe, a protective shell, a mounting bracket, and an electric fan. The temperature controller is installed on the upper rear side of the housing. Circulation pipes are connected to the left and right sides of the top of the temperature controller. A protective shell is fixedly installed from the top to the upper inner part of the housing. The protective shell surrounds the electric push rod. The circulation pipe extends into the protective shell. Mounting brackets are provided on both sides of the top of the protective shell. An electric fan is installed at the bottom of the mounting brackets and is located above the circulation pipe.

[0008] As an improvement to the above solution, a protective net is also included, with a protective net installed on the top of the mounting frame.

[0009] As an improvement to the above solution, it also includes a dual-axis motor, a lead screw, and a sliding frame. The dual-axis motor is installed inside the placement platform. The output shafts on the left and right sides of the dual-axis motor are respectively connected to lead screws through couplings. The two ends of the lead screws are threaded and threadedly engaged with the sliding frame. The sliding frame is slidably connected to the placement platform.

[0010] As an improvement to the above solution, it also includes an electric slide rail, an electric slider, and a clamping plate. An electric slide rail is provided on the side of the sliding frame that is far apart from each other. Electric sliders are symmetrically connected to the electric slide rail. A clamping plate is fixedly connected to the side of the electric slider and the side of the sliding frame that is close to each other. The clamping plate and its corresponding sliding frame slide together.

[0011] As an improvement to the above solution, it also includes a lifting plate, a pull ring, and a limiting block. The lifting plate is vertically slidably provided at the center of the top of the placement platform. A pull ring is provided on the front side of the lifting plate. A limiting block is fixedly connected to the front side of the placement platform. A sliding groove is provided on the front side of the lifting plate. The limiting block slides in cooperation with the sliding groove.

[0012] The beneficial effects are: 1. By integrating temperature control components, the utility model realizes adjustable control of the test environment temperature, and can simulate wear resistance tests under both high and low temperature conditions, thus achieving the ability to evaluate the wear resistance performance of metal surface coatings under different temperature environments, and improving the authenticity and reliability of test results.

[0013] 2. This utility model uses a dual-axis motor to drive the lead screw to rotate, enabling the sliding frame to automatically adjust the clamping position according to the size of the sample.

[0023] Example: A wear resistance testing device for metal surface coatings, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the device includes a housing 1, a placement platform 101, a sliding plate 2, an electric push rod 3, a connecting frame 4, an abrasion testing component 5, and a temperature control component. The placement platform 101 for placing the sample to be tested is bolted to the top of the housing 1. The sliding plates 2 are symmetrically connected on the left and right sides of the front of the housing 1 to assist operators in loading and unloading parts or observing the testing process. An electric push rod 3 with downward output is installed at the top inside the housing 1. The output end of the electric push rod 3 is connected to the connecting frame 4 by welding. The abrasion testing component 5 is set at the bottom of the connecting frame 4 to apply friction to the metal surface coating and detect its wear. A temperature control component is set at the connection between the rear and top of the housing 1 to regulate the temperature of the testing environment.

[0024] like Figures 2-4 As shown, the temperature control assembly includes a thermostat 6, a circulation pipe 7, a protective shell 8, a mounting bracket 9, an electric fan 10, and a protective net 11. The thermostat 6 is installed on the upper rear side of the housing 1. The circulation pipe 7 is connected to the left and right sides of the top of the thermostat 6. The protective shell 8 is fixedly installed from the top to the upper inner part of the housing 1. The protective shell 8 surrounds the electric push rod 3 and serves to protect and insulate the heat. The circulation pipe 7 extends into the protective shell 8. Mounting brackets 9 are provided on both sides of the top of the protective shell 8. An electric fan 10 is installed at the bottom of the mounting bracket 9 and is located above the circulation pipe 7 to accelerate airflow and improve temperature control efficiency. A protective net 11 is provided on the top of the mounting bracket 9 to prevent foreign objects from entering.

[0025] like Figure 6 and Figure 7 As shown, it also includes a dual-axis motor 12, a lead screw 13, a sliding frame 14, an electric slide rail 15, an electric slider 16, and a clamping plate 17. The dual-axis motor 12 is installed inside the placement stage 101. The output shafts on the left and right sides of the dual-axis motor 12 are respectively connected to the lead screw 13 through couplings. The two ends of the lead screw 13 are threaded and threadedly engaged with the sliding frame 14. The sliding frame 14 is slidably connected to the placement stage 101 and can move laterally under the drive of the lead screw 13, thereby adjusting the clamping position. An electric slide rail 15 is provided on the side of the sliding frame 14 that is far apart from each other. Electric sliders 16 are symmetrically slidably connected to the electric slide rail 15. The side of each electric slider 16 that is close to the sliding frame 14 is connected to the clamping plate 17 by bolts. The clamping plate 17 and its corresponding sliding frame 14 are slidably engaged and can be used to clamp samples of different sizes.

[0026] like Figures 5-7 As shown, it also includes a lifting plate 18, a pull ring 19, and a limiting block 20. The lifting plate 18 is vertically slidably provided at the top center of the placement platform 101. The front side of the lifting plate 18 is provided with a pull ring 19 for easy lifting by the operator. The front side of the placement platform 101 is connected to the limiting block 20 by bolts. The front side of the lifting plate 18 is provided with a sliding groove. The limiting block 20 slides with the sliding groove to play a guiding and limiting role.

[0027] When using this metal surface coating wear resistance testing device, the operator first places the metal sample to be tested on the placement platform 101 at the top of the housing 1, and starts the dual-axis motor 12. The dual-axis motor 12 drives the output shafts on both sides to rotate, which in turn drives the lead screw 13 to rotate through the coupling. Under the threaded engagement, the sliding frame 14 slides laterally along the placement platform 101, realizing automatic adjustment of the clamping position. Next, the electric slide rail 15 is powered on and runs, and the electric slider 16 slides back and forth along the electric slide rail 15, driving the clamping plate 17 fixed to it to move, thereby clamping samples of different sizes and ensuring that the samples are stable and do not shift during the test.

[0028] After the sample is clamped, the operator can observe the interior of the housing 1 through the sliding plate 2 on the front side and confirm that the installation is correct. Next, the operator activates the electric push rod 3. The electric push rod 3 extends downward, driving the connecting bracket 4 connected to its output end and the abrasion test component 5 at the bottom to descend together, so that the abrasion test component 5 contacts the sample surface and applies the set frictional force. At this time, the abrasion test component 5 begins to apply continuous abrasion to the sample surface, while monitoring and recording data for subsequent analysis of the abrasion resistance of the coating under specific temperature conditions.

[0029] Furthermore, operators can set the target temperature of the temperature control component according to testing requirements. The temperature controller 6 switches between heating and cooling modes based on the set value to achieve the required test environment temperature. For example, when abrasion resistance testing requires a high-temperature environment, the temperature of the temperature controller 6 is increased to raise the temperature of the medium in the circulation pipe 7, and the heat is transferred to the interior of the chamber 1 through the pipes, thereby increasing the temperature of the entire test space. Conversely, when low-temperature testing is required, the temperature of the temperature controller 6 is decreased, and the cooling system is used to lower the temperature of the circulating medium, thereby reducing the temperature of the test area. During this process, the electric fan 10 accelerates airflow, promotes uniform heat distribution, and ensures a constant and consistent test environment temperature.

[0030] During testing, if it is necessary to replace the sample or perform maintenance, the operator can pull the pull ring 19 on the front side of the lifting plate 18. With the guidance of the limit block 20 and the slide, the lifting plate 18 will be raised smoothly, thereby exposing the operating space under the placement platform 101, which is convenient for loading, unloading and cleaning.

[0031] The entire device achieves efficient and stable testing of the wear resistance of the metal coating under test under different temperature conditions through the coordinated operation of multiple components, improving testing accuracy and work efficiency, and is suitable for the universal testing needs of various specifications of samples.
