Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of impact resistance and sliding performance testing, specifically a testing device for the impact resistance and sliding performance of PVD coating. Background Technology
[0002] PVD coating is an advanced surface treatment technology that uses physical means to convert target materials into vapor or ions in a vacuum environment and deposit them onto a substrate to improve material properties. The impact resistance and sliding properties of PVD coatings are important indicators for evaluating their durability and reliability in practical applications.
[0003] According to Chinese Patent No. CN215004638U, a testing device for evaluating the impact resistance and sliding performance of PVD coatings includes: a ball-dropping device for dropping experimental balls; an impact-receiving platform, which is inclinedly positioned directly below the ball-dropping device, with a substrate of the coating to be tested on the impact-receiving platform, the surface of which is coated with the coating to be tested, and the experimental balls falling onto the coating to be tested; and a horizontally positioned sliding reset device, with the impact-receiving platform positioned on the sliding reset device, the sliding reset device being on the same straight line as the ejection direction of the experimental balls and in opposite directions, the sliding reset device being able to slide left and right and automatically reset.
[0004] The above scheme uses a free-falling ball to test the sample, which still has the following drawbacks: after the ball hits the sample, it will bounce off the sample. The trajectory of the bounced ball cannot be predicted, which may cause the ball to hit the surrounding equipment or personnel, reducing the safety during the test. Utility Model Content
[0005] The purpose of this invention is to provide a device for testing the impact and sliding performance of PVD coatings, in order to solve the problem that the trajectory of the ejected ball cannot be predicted, which may cause the ball to collide with surrounding equipment or personnel, reducing safety during testing.
[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a testing device for the impact and sliding performance of a PVD coating, comprising a mounting plate, the mounting plate being fixed to the top surface of a testing platform, a sliding opening being provided on one side of the mounting plate, a mounting folding plate being fixed on one side of the mounting plate, a sliding hole being provided on one side of the mounting folding plate, a sliding rod being slidably inserted into the sliding hole, an impact plate being fixed to one end of the sliding rod, a spring being wound around the surface of the sliding rod, one end of the spring being fixed to the inside of the mounting folding plate, and the other end of the spring being fixed to one side of the impact plate.
[0007] Preferably, a sliding plate is fixed to the other end of the sliding rod, and a position plate is fixed to both sides of the sliding plate. Several scale strips are fixed to the top surface of the detection platform, and several fixing grooves are opened on the top surface of the detection platform. Positioning strips are fixed inside the fixing grooves.
[0008] Preferably, a replacement plate is detachably provided on one side of the impact plate, and a plurality of limiting grooves are provided on the side of the impact plate near the replacement plate. Two limiting strips are fixed on the side of the replacement plate near the impact plate, and the limiting grooves and limiting strips are slidably inserted.
[0009] Preferably, a baffle plate is fixed on one side of the testing station.
[0010] Preferably, the bottom surface of the impact plate is provided with a plurality of positioning grooves, and rollers are rotatably arranged inside the positioning grooves.
[0011] Preferably, support columns are fixed at the four corners of the bottom surface of the testing platform, and anti-slip pads are fixed at the bottom of the support columns.
[0012] Compared with existing technologies, the PVD coating impact resistance and sliding performance testing device using the above technical solution has the following advantages:
[0013] First, the staff will place the PVD-coated mold on the top surface of the testing table, directly in front of the impact plate. Then, the staff will apply a force to the right to the sliding rod through the sliding plate, which will cause the sliding rod and the impact plate to move to the right. The staff can judge the length of the spring being stretched by comparing the position of the indicator plate and the scale bar, and thus control the magnitude of the impact force applied by the impact plate to the mold. During the test, the staff will remove the force applied to the sliding plate. At this time, the stretched spring will return to its original position and apply a force to the left to the sliding rod, which will cause the impact plate to apply a force to the left to the mold, so that the mold slides to the left on the top surface of the testing table. This reduces the probability of the mold hitting nearby equipment and staff, and increases the safety during the test.
[0014] 2. Before testing the impact resistance of the PVD coating on the mold surface, the staff will first move the replacement plate above the impact plate, then insert the limiting strip into the limiting groove and fix the replacement plate on one side of the impact plate. When the impact plate hits the mold, the staff will install replacement plates of different hardness on the impact plate. The same mold can be tested using replacement plates of different hardness, and the impact resistance of the mold under different working environments can be tested.
[0015] Third, when the impact plate slides on the top surface of the testing table, the roller will roll on the top surface of the testing table, which can reduce the friction when the impact plate slides on the testing table, reduce the impact of the friction between the impact plate and the testing table on the test results, and increase the accuracy of the test results.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] like Figures 1-3 As shown, a testing device for the impact and sliding resistance of a PVD coating includes a mounting plate 1, which is fixed to the top surface of a testing platform 2. A sliding opening 3 is provided on one side of the mounting plate 1, and a mounting folding plate 4 is fixed to one side of the mounting plate 1. A sliding hole 5 is provided on one side of the mounting folding plate 4, and a sliding rod 6 is slidably inserted into the sliding hole 5. An impact plate 8 is fixed to one end of the sliding rod 6, and a spring 7 is wound around the surface of the sliding rod 6. One end of the spring 7 is fixed to the inside of the mounting folding plate 4, and the other end of the spring 7 is fixed to one side of the impact plate 8. A sliding plate 9 is fixed to the other end of the sliding rod 6, and indicator plates 10 are fixed to both sides of the sliding plate 9. Several scale strips 11 are fixed to the top surface of the testing platform 2, and several fixing grooves 12 are provided on the top surface of the testing platform 2. Positioning strips 13 are fixed inside the fixing grooves 12.
[0023] In use, the operator first places the PVD-coated mold on the top surface of the testing table 2, directly in front of the impact plate 8. Then, the operator applies a force to the right to the sliding rod 6 through the sliding plate 9, which in turn moves the sliding rod 6 and the impact plate 8 to the right. The operator can determine the length of the stretched spring 7 by comparing the positions of the indicator plate 10 and the scale bar 11, and thus control the magnitude of the impact force applied by the impact plate 8 to the mold. During testing, the operator removes the force applied to the sliding plate 9. At this time, the stretched spring 7 will return to its original position and apply a force to the left to the sliding rod 6, which will cause the impact plate 8 to apply a force to the left to the mold, making the mold slide to the left on the top surface of the testing table 2. This reduces the probability of the mold colliding with nearby equipment and operators, and increases safety during testing.
[0024] like Figure 2 and Figure 4 As shown, a replacement plate 15 is detachably provided on one side of the impact plate 8. Several limiting grooves 16 are provided on the side of the impact plate 8 near the replacement plate 15. Two limiting strips 17 are fixed on the side of the replacement plate 15 near the impact plate 8. The limiting grooves 16 and the limiting strips 17 are slidably inserted. A blocking plate 14 is fixed on one side of the testing table 2.
[0025] In use, before testing the impact resistance of the PVD coating on the mold surface, the operator will first move the replacement plate 15 above the impact plate 8, and then insert the limiting strip 17 into the limiting groove 16 to fix the replacement plate 15 on one side of the impact plate 8. When the impact plate 8 hits the mold, the operator will install replacement plates 15 of different hardness on the impact plate 8. The same mold can be tested by using replacement plates 15 of different hardness, and the impact resistance of the mold under different working environments can be tested.
[0026] like Figure 1 and Figure 4 As shown, the bottom surface of the impact plate 8 is provided with several positioning grooves 18, and the inside of the positioning grooves 18 is provided with rollers 19. Support columns 20 are fixed at the four corners of the bottom surface of the testing table 2, and anti-slip pads 21 are fixed at the bottom of the support columns 20.
[0027] During use, when the impact plate 8 slides on the top surface of the testing table 2, the roller 19 will roll on the top surface of the testing table 2, which can reduce the friction when the impact plate 8 slides on the testing table 2, reduce the influence of the friction between the impact plate 8 and the testing table 2 on the test results, and increase the accuracy of the test results.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
