Description

Technical Field

[0001] The present application relates to the technical field of alloy material wear resistance testing, and in particular to an alloy material wear resistance testing device and a testing process. Background Art

[0002] At present, with the rapid development of modern industry, alloy materials are widely used in machinery, construction, aerospace and other fields. Especially in the environment of high strength and high wear resistance, the wear resistance of alloy materials has become one of the key factors. In particular, alloy materials treated by the boriding process diffuse the boron element into the surface of the alloy material to form a high-hardness boride layer, thereby significantly improving the wear resistance and corrosion resistance of the material. They are widely used in the manufacture of drilling tools, cutting tools and other equipment that withstand high friction and high stress. However, during use, the wear resistance of alloy materials is directly affected by the thickness of the boriding layer. Therefore, accurately detecting the wear resistance of alloy materials has become an important link in ensuring the durability and life of the materials.

[0003] Existing methods for testing the wear resistance of alloy materials are generally divided into the following categories: one is a friction and wear test based on laboratory conditions, such as evaluating the wear resistance by rubbing the alloy material against a standard material and measuring its surface loss or mass change; the other is a wear test that simulates actual working conditions, such as performing a wear test on the alloy material under high temperature, acid or other specific environments; finally, the alloy material after the test is subjected to a microscopic observation of the wear marks to provide wear-related detection information, and the wear resistance and hardness of the material surface can be evaluated by combining this information.

[0004] Although the existing detection methods can provide more intuitive material wear resistance data, these material wear resistance data need to be measured by other equipment in the subsequent operation to be accurately obtained, especially the thickness change of the boriding layer after the detection is completed, which often requires microscopic thickness measurement to obtain detailed data, and cannot intuitively display the thickness change of the boriding layer. The thickness of the boriding layer is one of the important factors affecting the wear resistance of alloy materials. Its thickness change is of great significance to the attenuation of material wear resistance, especially under extreme working conditions such as drilling tools, the actual wear amount of alloy materials is difficult to evaluate; secondly, the friction and wear test can only obtain overall wear resistance data, but cannot accurately distinguish the wear difference between the boriding layer and the friction matrix, and cannot provide the specific wear process of the boriding layer. Summary of the invention

[0005] The present application provides an alloy material wear resistance testing device and testing process. The testing device can intuitively detect the thickness of the boride layer without the need for additional testing equipment, and can also apply complex dynamic load conditions, effectively reducing the cost of testing and use, and significantly improving the evaluation effect of the alloy material's wear resistance.

[0007] By adopting the above technical solution, the combination of the lifting piece and the heating piece can not only simulate the actual friction environment, but also heat the sample to simulate the wear resistance of the alloy material under high temperature. At the same time, the alloy material sample is pressed onto the friction piece by the pressure piece, so that the pressure applied during the detection process is more accurate and controllable, ensuring that the pressure during the friction process is evenly distributed, further improving the accuracy of the test results, and the pressure piece intuitively displays the wear thickness of the sample after the test, which provides an intuitive basis for subsequent data analysis and enhances the reliability of the test results. In addition, the nozzles and multiple groups of nozzles ensure that the silver nitrate solution can be evenly sprayed on the friction substrate and alloy material samples during the test, which not only simulates the working conditions of the alloy material in a wet environment, but also helps to detect the wear resistance of the material in a corrosive environment through the solution penetration and friction process. The design of multiple groups of nozzles increases the coverage of the liquid, ensuring that the solution can fully act on the sample surface, improving the comprehensiveness and accuracy of the test; at the same time, the silver nitrate solution is used as the detection medium, which can produce color changes (such as blackening) through chemical reactions when it rubs with the alloy material sample, which provides an intuitive visual signal for the detection.

[0008] Preferably, the pressure-applying member comprises a hydraulic cylinder, a clamping rod and a liquid display tube, the hydraulic cylinder is fixedly mounted on the rotating plate, the clamping rod is coaxially slidably penetrated on the hydraulic cylinder, a piston block is fixedly mounted on the clamping rod, the piston block is located in the hydraulic cylinder, the piston block divides the hydraulic cylinder into two independent chambers, a pressure chamber and a regulating chamber, the pressure chamber is located at one end of the hydraulic cylinder close to the rotating plate, and the pressure chamber is filled with hydraulic oil; one end of the clamping rod is fixedly connected to the abutment plate, the other end of the clamping rod is fixedly provided with an anti-slip portion, a clamping spring is sleeved on the clamping rod, one end of the clamping spring is fixedly connected to one end of the hydraulic cylinder away from the rotating plate, and the other end of the clamping spring is fixedly connected to the anti-slip portion; the liquid display tube is fixedly mounted on the hydraulic cylinder, one end of the liquid display tube is connected to the pressure chamber, the liquid display tube is made of transparent material, a scale is provided on the liquid display tube, and the diameter of the liquid display tube is much smaller than the diameter of the hydraulic cylinder.

[0009] By adopting the above technical scheme, the hydraulic cylinder, clamping rod and clamping spring are set so that the alloy material sample can be evenly stressed during the detection process. At the same time, the liquid display tube is made of transparent material and is provided with a scale, which can intuitively display the height change of the hydraulic oil in the pressure chamber, so that the operator can not only conveniently monitor the changes in the applied pressure during the detection process, but also intuitively display the wear thickness of the alloy material sample after the detection is completed; conventional wear thickness measurements require additional detection equipment, and the transfer of alloy material samples is involved in this process, which invisibly increases data errors and also increases the detection cost. By adopting the above technical scheme, by utilizing Pascal's principle, the thickness of the boride layer can be intuitively detected without additional detection equipment, effectively reducing the cost of detection and use, reducing unnecessary measurement errors, simplifying the operation process, and significantly improving the evaluation effect of the wear resistance of alloy materials.

[0010] Preferably, the load assembly also includes a toggle rod and a connecting rod, the toggle rod is arranged above the rotating plate, one end of the toggle rod is rotatably connected to the mounting plate, the connecting rod is arranged at an end of the rotating plate away from the vertical plate, one end of the connecting rod is rotatably connected to the rotating plate, and the other end of the connecting rod is rotatably connected to an end of the toggle rod away from the mounting plate. The rotating plate can be driven to rotate by the toggle rod, thereby controlling the pressing of the pressure piece on the alloy material sample, thereby facilitating the installation of the alloy material sample.

[0011] By adopting the above technical scheme, the linkage structure of the set rotating rod and the connecting rod not only allows the user to flexibly adjust the pressing position of the pressure piece according to alloy material samples of different sizes and shapes, so as to adapt to diverse testing needs, but also avoids the cumbersome adjustment process when installing the sample, and ensures that the pressure piece presses the alloy material sample onto the friction piece while only needing to lift the rotating rod to easily release the pressing of the alloy material sample by the pressure piece, so that the alloy material sample can be quickly and accurately installed in place, greatly improving the operating efficiency, and can effectively avoid the risk of misoperation that may occur during the installation process, improve the safety of operation, and avoid experimental errors caused by human factors, thereby ensuring the reliability and accuracy of detection.

[0012] Preferably, the load assembly also includes a load part, which includes an impact cylinder, a load crankshaft, an impact rod, a driving bevel gear, a driven bevel gear and a transmission rod. The impact cylinder is fixedly arranged on the rotating plate, and an impact block is slidably arranged in the impact cylinder. A rotating seat is fixedly arranged on the dial rod, and the load crankshaft is rotatably arranged on the dial rod through the rotating seat. One end of the impact rod is rotatably connected to the load crankshaft, and the other end of the impact rod is rotatably connected to the impact block; the driving bevel gear is arranged on the end of the connecting shaft away from the bearing plate, and the driving bevel gear is connected to the transmission The crankshaft is connected through one end of the bearing plate, and a rotating shaft is coaxially fixed to one end of the driven bevel gear. The driven bevel gear is rotatably arranged on the dial rod through the rotating shaft. The active bevel gear is meshed with the driven bevel gear. One end of the transmission rod is rotatably connected to an end of the driven bevel gear away from the rotating shaft, and the other end of the transmission rod is rotatably connected to the load crankshaft. The transmission crankshaft is meshed with the active bevel gear and the driven bevel gear to rotate the load crankshaft, so that the impact block can slide back and forth in the impact cylinder, thereby realizing the application of dynamic load to the alloy material sample.

[0013] By adopting the above technical solution, the impact cylinder, impact rod, load crankshaft, bevel gear, transmission rod and other components are set, so that the equipment can apply dynamic load to the alloy material sample, so as to simulate the periodic impact and variable load that the alloy material is subjected to in the actual use environment, which helps to more realistically reproduce the wear resistance performance of the alloy material under complex working conditions. At the same time, the speed and frequency of the reciprocating sliding of the impact block in the impact cylinder can be adjusted, so as to realize accurate detection of the wear resistance of different materials under different load conditions. This dynamic load is more representative than the conventional dynamic pressure method, so that the test results are closer to the actual working conditions, thereby improving the accuracy of the detection.

[0014] Preferably, an adjusting member is provided on the transmission crankshaft, and the adjusting member is located below the load component, and the adjusting member includes a locking plate, a rotating block, a connecting shaft, a locking rod and an adjusting spring, the locking plate is rotatably arranged on the bearing plate, the locking plate is fixedly connected to one end of the transmission crankshaft passing through the bearing plate, a locking groove is provided on the locking plate, the locking groove is arranged in a ratchet shape, the rotating block is rotatably arranged in the locking groove, a fixing seat is fixedly provided on the mounting plate, the connecting shaft is rotatably penetrated on the fixing seat, one end of the connecting shaft is fixedly connected to a surface of the rotating block facing away from the locking groove, and the connecting shaft The other end is coaxially fixedly connected with the active bevel gear, a receiving groove is provided on a surface of the rotating block close to the connecting shaft, a rotating shaft is fixedly arranged in the receiving groove, one end of the locking rod is rotatably connected with the rotating shaft, the locking rod is rotatably arranged in the receiving groove by the rotating shaft, the adjusting spring is arranged in the receiving groove, one end of the adjusting spring is fixedly connected to the locking rod, and the other end of the adjusting spring is fixedly connected to the inner wall of the receiving groove, when the rotating block rotates, one end of the locking rod can be plugged into the inner wall of the locking groove under the action of the adjusting spring, so that the connecting shaft and the transmission crankshaft rotate synchronously.

[0015] By adopting the above technical solution, the set adjustment member can allow the applied load to be dynamically adjusted during the detection process, that is, when the motor rotates forward, since the locking groove is set in a ratchet shape, one end of the locking rod can be engaged with the inner wall of the locking groove under the action of the adjustment spring, and the connecting shaft and the transmission crankshaft rotate synchronously; when the motor is reversed, the locking rod and the inner wall of the locking groove cannot be smoothly engaged, and the transmission crankshaft cannot drive the connecting shaft to rotate, thereby controlling the start of the load member, allowing the detection equipment to adapt to different types of alloy materials and test requirements, and also allowing the load member to generate more complex dynamic loads. This dynamic adjustment capability makes the detection more flexible and can cope with various complex test conditions.

[0016] Preferably, a calibration component is provided in the liquid accumulation barrel, and the calibration component includes a calibration plate, a driving plate, a first telescopic rod and a second telescopic rod. A support plate is provided on the mounting seat, and one end of the bearing plate away from the mounting plate is overlapped on the support plate, and one end of the calibration plate passes through the support plate and the barrel wall of the liquid accumulation barrel in sequence, and the end of the calibration plate located in the liquid accumulation barrel is provided with a first wedge-shaped surface, and the calibration plate is slidably connected to the support plate and the liquid accumulation barrel; one end of the driving plate passes through the support plate and the barrel wall of the liquid accumulation barrel in sequence, and the end of the driving plate located in the liquid accumulation barrel is provided with a second wedge-shaped surface, and the second wedge-shaped surface is in contact with the outer side of the friction member.

When the lifting member drives the friction member to move downward, the extended end of the second telescopic rod will be compressed, so that the extended end of the first telescopic rod will push the calibration plate out to support the alloy material sample.

[0017] By adopting the above technical solution, the purpose of setting the calibration piece is to distinguish the wear amount between the alloy material sample and the friction matrix used for detection. The conventional detection method is to measure the two separately, which cannot intuitively display the wear amount and wear thickness of the two. The set calibration piece is equivalent to setting a reference benchmark. When the lifting part drives the friction part to slide downward, the calibration plate simultaneously supports the alloy material sample. At this time, there is a value in the liquid display tube. By comparing and analyzing this value with the value of the liquid display tube when the motor stops, the thickness of the boriding layer can be intuitively detected, and the wear difference between the boriding layer of the alloy material and the friction matrix can also be distinguished, which significantly improves the evaluation effect of the wear resistance of the alloy material. In addition, when the lifting part drives the friction part to move downward, the second telescopic rod is compressed, thereby pushing the first telescopic rod to extend, so that the calibration plate supports the alloy material sample. This linkage setting avoids the errors that may be introduced by manual operation. The automatic calibration mechanism helps to reduce the influence of human errors on the wear resistance test results, ensures the standardization of the detection process, and improves the accuracy and reliability of the detection.

[0018] Preferably, the heating element includes a turntable, a driving gear, a driven gear and a magnetic block. The turntable is fixedly provided with a rotating part, and the rotating part is rotatably connected to the liquid accumulation bucket and the mounting seat respectively. The driving end of the lifting member passes through the mounting seat, the rotating part and the turntable in sequence and is fixedly connected to the friction member. The rotating part is slidably connected to the driving end of the lifting member, and the driven gear is fixedly sleeved on the rotating part. The driving gear is fixedly connected to the output end of the motor, and the driving gear is meshed with the driven gear. The magnetic blocks are provided in several groups, and the magnetic blocks are embedded in the turntable, and the magnetic poles of two adjacent magnetic blocks on the turntable are opposite. When the motor drives the turntable to rotate, the alloy material sample will be heated by the magnetic block.

[0019] By adopting the above technical solution, the structure of the turntable and the magnetic block is set, and the characteristic of the conductor being able to quickly heat up the conductor is utilized according to the principle of electromagnetic induction, so that the alloy material can be heated to a preset temperature in a short time, while ensuring that the surface and interior of the alloy material sample maintain a uniform temperature distribution during the entire friction test, thereby providing more accurate wear resistance test results, which not only improves the detection efficiency, but also makes the entire test process more compact and reduces waiting time; in addition, the transmission system of the active gear and the driven gear is connected to the controller, and the working state of the heating element can be accurately adjusted through the control system, and the heating temperature of the sample can be easily controlled. The conductor is heated according to the principle of electromagnetic induction, so that the heating effect can be flexibly adjusted according to different material properties to meet the testing needs of different alloy materials.

[0020] Preferably, the toggle rod and the connecting rod are each provided with two groups, and the two groups of the toggle rod and the connecting rod are symmetrically arranged along the width direction of the bearing plate, and an elastic telescopic rod is arranged on the toggle rod, one end of the elastic telescopic rod is rotatably connected to the toggle rod, and the other end of the elastic telescopic rod is rotatably connected to the mounting plate, when the abutment plate presses the alloy material sample onto the friction part, the elastic telescopic rod can limit the rotation of the toggle rod, thereby ensuring that the alloy material sample is in full contact with the friction part.

[0021] By adopting the above technical solution, the turning rod and the connecting rod are set into two groups and are symmetrically set, which improves the uniformity of pressure, effectively improves the stability of the rotating plate, avoids the error caused by uneven force on the sample, and ensures that the pressure piece and the load piece can stably act on the alloy material sample; the set elastic telescopic rod can ensure that during the entire detection process, the abutment plate can always press the sample against the friction piece, so that the sample and the friction piece are in full contact, and can reduce the interference of vibration generated during the pressure and friction process on the detection result. The stable pressure state and friction force can more truly reflect the wear resistance of the alloy material.

[0022] On the other hand, the present application provides a detection process of an alloy material wear resistance detection device, comprising the following steps: S1. Lift the end of the lever away from the mounting plate, and the lifting member lifts the friction base into place. The alloy material sample is installed on the slide seat through the mounting hole. Then, lower the lever to make the abutment plate press the alloy material sample. Start the pressure pump, and the silver nitrate solution flows out of the nozzle. S2, start the motor to rotate, the transmission crankshaft drives the alloy material sample to rub against the friction substrate, and at the same time the turntable rotates to heat the alloy material, the locking plate drives the rotating shaft to rotate, the driven bevel gear drives the load crankshaft to rotate through the transmission rod, and the impact block continuously applies impact pressure to the alloy material sample; S3. The color sensor detects that the color of the silver nitrate solution flowing through the alloy material sample turns black, the motor stops rotating, and the level change of the hydraulic oil in the liquid display tube is recorded. The lifting member drives the friction base to move downward, and the calibration plate extends to support the alloy material sample, and the level change of the hydraulic oil in the liquid display tube is recorded again; S4. Based on the liquid level results of the two liquid display tubes, combined with the changes in load, temperature and friction, analyze the wear resistance of the alloy material and evaluate its performance in high temperature environment.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The hydraulic cylinder, the clamping rod and the clamping spring are arranged so that the alloy material sample can be uniformly stressed during the detection process. At the same time, the liquid display tube is made of transparent material and is provided with a scale, which can intuitively display the height change of the hydraulic oil in the pressure chamber, so that the operator can not only conveniently monitor the change of the pressure applied during the detection process, but also can intuitively display the wear thickness of the alloy material sample after the detection is completed; conventional wear thickness measurement requires additional detection equipment, and the transfer of alloy material samples is involved in this process, which invisibly increases the data error and also increases the detection cost. The above technical solution, by using the Pascal principle, can intuitively detect the thickness of the boride layer without additional detection equipment, effectively reducing the cost of detection and use, reducing unnecessary measurement errors, simplifying the operation process, and significantly improving the evaluation effect of the wear resistance of alloy materials; 2. The impact cylinder, impact rod, load crankshaft, bevel gear, transmission rod and other components are set up, so that the equipment can apply dynamic load to the alloy material sample, so as to simulate the periodic impact and variable load that the alloy material bears in the actual use environment, which helps to more realistically reproduce the wear resistance performance of the alloy material under complex working conditions. At the same time, the speed and frequency of the reciprocating sliding of the impact block in the impact cylinder can be adjusted, so as to realize the accurate detection of the wear resistance of different materials under different load conditions. This dynamic load is more representative than the conventional dynamic pressure method, making the test results closer to the actual working conditions, thereby improving the accuracy of the detection; 3.

The nozzles and multiple groups of nozzles ensure that the silver nitrate solution can be evenly sprayed on the friction substrate and alloy material samples during the test. This not only simulates the working conditions of the alloy material in a wet environment, but also helps to detect the wear resistance of the material in a corrosive environment through the solution penetration and friction process.

There are several groups of magnetic blocks 344, which are embedded on the turntable 341, and the magnetic poles of two adjacent magnetic blocks 344 on the turntable 341 are opposite.

[0047] The nozzle 36 is fixed on the liquid storage barrel 31, and the nozzle 36 is located above one side in the width direction of the friction base material 322.

[0048] When the color sensor 39 detects that the silver nitrate solution flowing through the alloy material sample turns black, the controller 24 controls the motor 21 to stop rotating, and the controller 24 controls the pressure pump 38 to turn off. This means that the boronized layer on the surface of the alloy material is worn away, and the base material inside the alloy material reacts chemically with the silver nitrate solution, causing the silver nitrate solution flowing through to turn black.

At the same time, according to Pascal's principle, in the connected pipes, the pressure of the fluid at the same height is the same. Since the diameter of the liquid display tube 423 is much smaller than the diameter of the hydraulic cylinder 421, a slight change in the hydraulic oil level in the hydraulic cylinder 421 will cause a relatively large change in the fluid level in the liquid display tube 423, thereby "magnifying" the slight change in the hydraulic cylinder 421.
