Description

Technical Field

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

[0002] At present, with the rapid development of modern industry, alloy materials are widely used in fields such as machinery, construction, aerospace, etc. Especially in an environment with high-strength and high-wear resistance requirements, the wear resistance of alloy materials becomes one of the key factors. In particular, alloy materials treated by the boronizing process, by diffusing boron elements into the surface layer of the alloy material to form a high-hardness boride layer, thus significantly improving the wear resistance and corrosion resistance of the material, are widely used in the manufacture of equipment such as drill bits and cutting tools that bear high friction and high stress. However, during use, the wear resistance of alloy materials is directly affected by the thickness of the boronizing layer. Therefore, accurately detecting the wear resistance of alloy materials has become an important link in ensuring the durability and lifespan of the materials.

[0003] Existing wear resistance detection methods for alloy materials are generally divided into the following categories: One category is friction and wear tests based on laboratory conditions. For example, after rubbing an alloy material with a standard material, the surface loss or mass change is measured to evaluate wear resistance; another category is wear tests that simulate actual working conditions. For example, under high temperature, acidic or other specific environments, wear tests are carried out on alloy materials; finally, microscopic observation of the worn alloy material is carried out to provide wear-related detection information. By integrating this information, the wear resistance and hardness of the material surface can be evaluated.

[0004] Although existing detection methods can provide relatively intuitive material wear resistance data, these material wear resistance data need to be accurately obtained through subsequent operations on other equipment. Especially after the detection, the thickness change of the boronizing layer often requires microscopic thickness measurement to obtain detailed data, and it is impossible to intuitively display the thickness change of the boronizing layer. As one of the important factors affecting the wear resistance of alloy materials, the thickness change of the boronizing layer is of great significance for the attenuation of material wear resistance. Especially in extreme working conditions such as drill bits, it is difficult to evaluate the actual wear amount of alloy materials; secondly, friction and wear tests can only obtain overall wear resistance data, and cannot accurately distinguish the wear differences between the boronizing layer and the friction matrix, and cannot provide the specific wear process of the boronizing layer. Summary of the Invention

[0005] The present application provides a wear resistance detection device and detection process for alloy materials. This detection device can directly detect the thickness of the boronizing layer without additional detection equipment, and can also apply complex dynamic load conditions, effectively reducing the cost of detection use and significantly improving the evaluation effect of the wear resistance of alloy materials.

[0006] In a first aspect, a wear resistance detection device for an alloy material provided by the present application adopts the following technical solution:

[0007] A wear resistance detection device for an alloy material, comprising:

[0011] A friction component, the friction component includes a liquid accumulation bucket, a friction part, a lifting part and a heating part, the liquid accumulation bucket is fixedly arranged on the installation seat, the friction part is arranged in the liquid accumulation bucket, the lifting part is fixedly arranged on the installation seat, the lifting part is located below the friction part, the driving end of the lifting part is connected with the friction part, the friction part can move up and down in the vertical direction under the drive of the lifting part, the heating part is rotatably arranged on the inner wall of the liquid accumulation bucket, the heating part is in transmission connection with the motor, and the heating part can rotate to heat the alloy material sample, so as to simulate high-temperature environmental conditions;

[0012] The friction member includes a friction base and a friction substrate, the friction base is fixedly connected to the driving end of the jacking member, the friction substrate is fixedly embedded in the friction base, a nozzle is fixedly provided on the liquid accumulation barrel, the nozzle is located above one side in the width direction of the friction base, and a plurality of nozzles are provided on the nozzle; a liquid storage tank is provided on the mounting plate, a pressure pump is provided on the liquid storage tank, the pressure pump is transmission-connected to one end of the nozzle, the pressure pump is electrically connected to the controller, the liquid storage tank is filled with silver nitrate solution, a color sensor is provided on the inner wall of the liquid accumulation barrel, the color sensor is located on the side of the friction base away from the nozzle, and the color sensor is electrically connected to the controller; when the color sensor detects that the color of the silver nitrate solution flowing through the alloy material sample becomes black, the controller controls the motor to stop rotating, and at the same time, the controller controls the pressure pump to turn off;

[0013] A load assembly, the load assembly includes a rotating plate, a pressure piece and an abutment plate, a vertical plate is fixed on the load-bearing plate, one end of the rotating plate is rotatably connected to the vertical plate, the pressure piece is arranged on the rotating plate, and the abutment plate is arranged on the pressure piece, and the side of the abutment plate facing away from the pressure piece abuts against the alloy sample, and the pressure piece presses the alloy material sample onto the friction piece through the abutment plate. At the same time, after the wear resistance performance test is completed, the pressure piece can intuitively display the worn thickness of the alloy material sample.

[0014] By adopting the above technical solution, the combination of the lifting part and the heating part can not only simulate the actual friction environment, but also heat the sample to simulate the wear resistance of the alloy material at high temperature. At the same time, the alloy material sample is pressed against the friction part by the pressure part, making the pressure applied during the test more precise and controllable, ensuring that the pressure is evenly distributed during the friction process, further improving the accuracy of the test results. In addition, the pressure part 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.

[0015] In addition, the arranged nozzle and multiple groups of spray heads ensure that silver nitrate solution can be evenly sprayed on the friction substrate and alloy material sample during the test. This not only simulates the working conditions of the alloy material in a humid environment but also helps detect the wear resistance of the material in a corrosive environment through the penetration of the solution and the friction process. The design of multiple groups of spray heads increases the liquid coverage range, ensuring that the solution can fully act on the sample surface, improving the comprehensiveness and accuracy of the test. At the same time, using silver nitrate solution as the detection medium can produce a color change (such as turning black) through a chemical reaction when it rubs against the alloy material sample, which provides an intuitive visual signal for detection. Compared with the conventional method of measuring the sample after a specified time or a specified number of friction times, this can not only effectively judge the wear degree and time of the sample under friction and corrosion conditions, avoid relying on complex instrument detection, simplify the operation process, but also accurately detect the thickness of the boronized layer on the sample while detecting wear resistance. In addition, the arranged color sensor can timely prompt that the sample has reached the critical state of wear, avoiding excessive friction or damage to the sample and ensuring the accuracy of the detection result.

[0016] Preferably, the pressing member includes a hydraulic cylinder, a pressing rod, and a liquid display tube. The hydraulic cylinder is fixedly arranged on the rotating plate. The pressing rod coaxially and slidably penetrates through the hydraulic cylinder. A piston block is fixedly arranged on the pressing rod. The piston block is located inside the hydraulic cylinder. The piston block divides the hydraulic cylinder into two independent chambers, namely a pressure application chamber and an adjustment chamber. The pressure application chamber is located at one end of the hydraulic cylinder close to the rotating plate, and the pressure application chamber is filled with hydraulic oil. One end of the pressing rod is fixedly connected to the abutting plate, and an anti-detachment portion is fixedly arranged at the other end of the pressing rod. A pressing spring is sleeved on the pressing rod. One end of the pressing spring is fixedly connected to the end of the hydraulic cylinder away from the rotating plate, and the other end of the pressing spring is fixedly connected to the anti-detachment portion. The liquid display tube is fixedly arranged on the hydraulic cylinder. One end of the liquid display tube is communicated with the pressure application chamber. The liquid display tube is made of a transparent material. A scale is arranged on the liquid display tube, and the diameter of the liquid display tube is much smaller than the diameter of the hydraulic cylinder.

[0017] By adopting the above technical solution, the hydraulic cylinder, clamping rod and clamping spring are set 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 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 this process involves the transfer of alloy material samples, which invisibly increases data errors and also increases the detection cost. By adopting the above technical solution, by utilizing the Pascal principle, the thickness of the boride layer can be intuitively detected without additional detection equipment, effectively reducing the cost of detection, reducing unnecessary measurement errors, simplifying the operation process, and significantly improving the evaluation effect of the wear resistance of alloy materials.

[0018] Preferably, the load assembly further 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 member on the alloy material sample, thereby facilitating the installation of the alloy material sample.

[0019] By adopting the above technical solution, the linkage structure of the dial 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, thereby adapting to diverse testing needs, but also avoids the tedious adjustment process when installing the sample, ensuring that the pressure piece presses the alloy material sample onto the friction piece while only needing to lift the dial rod to easily release the pressure of the pressure piece on the alloy material sample, so that the alloy material sample can be installed quickly and accurately, greatly improving the operating efficiency, and can effectively avoid the risk of misoperation that may occur during the installation process, thereby improving the safety of the operation, and avoiding experimental errors caused by human factors, thereby ensuring the reliability and accuracy of the detection.

[0020] Preferably, the load assembly further includes a load part, and the load part 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 mounted on the rotating plate, and an impact block is slidably arranged in the impact cylinder. A rotating seat is fixedly provided 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 rotatably connected to the transmission The crankshaft is connected through one end of the carrying 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, and the active bevel gear is meshed with the driven bevel gear. One end of the transmission rod is rotationally connected to the end of the driven bevel gear away from the rotating shaft, and the other end of the transmission rod is rotationally 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 slides back and forth in the impact cylinder, thereby realizing the application of dynamic load to the alloy material sample.

[0021] By adopting the above-mentioned 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, thereby simulating 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 testing 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.

[0022] Preferably, an adjusting member is provided on the driving crankshaft. The adjusting member is located below the load assembly. The adjusting member includes a locking disc, a rotating block, a connecting shaft, a locking rod and an adjusting spring. The locking disc is rotatably arranged on the bearing plate. The locking disc is fixedly connected to one end of the driving crankshaft passing through the bearing plate. A locking groove is formed on the locking disc. The locking groove is arranged in a ratchet shape. The rotating block is rotatably arranged in the locking groove. A fixed seat is fixedly provided on the mounting plate. The connecting shaft is rotatably inserted through the fixed seat. One end of the connecting shaft is fixedly connected to a surface of the rotating block facing away from the locking groove. The other end of the connecting shaft is coaxially and fixedly connected to the driving bevel gear. A receiving groove is formed on a surface of the rotating block close to the connecting shaft. A rotating shaft is fixedly provided in the receiving groove. One end of the locking rod is rotatably connected to the rotating shaft. The locking rod is rotatably arranged in the receiving groove through 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. The other end of the adjusting spring is fixedly connected to the inner wall of the receiving groove. During the rotation of the rotating block, one end of the locking rod can be inserted into the inner wall of the locking groove under the action of the adjusting spring, so that the connecting shaft and the driving crankshaft rotate synchronously.

[0023] By adopting the above technical solution, the provided adjusting member can allow dynamic adjustment of the applied load during the detection process. That is, when the motor rotates forward, since the locking groove is arranged in a ratchet shape, one end of the locking rod can be clamped with the inner side wall of the locking groove under the action of the adjusting spring, and the connecting shaft and the driving crankshaft rotate synchronously. When the motor rotates reversely, the locking rod cannot be smoothly clamped with the inner peripheral wall of the locking groove, and the driving crankshaft cannot drive the connecting shaft to rotate. In this way, the start of the load member can be controlled, enabling the detection device to adapt to different types of alloy materials and test requirements, and also enabling the load member to generate more complex dynamic loads. This dynamic adjustment ability makes the detection more flexible and can cope with various complex test conditions.

[0024] Preferably, a calibration member is provided inside the liquid accumulation bucket. The calibration member 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. One end of the bearing plate away from the mounting plate is lapped on the support plate. One end of the calibration plate sequentially passes through the support plate and the barrel wall of the liquid accumulation bucket. One end of the calibration plate located inside the liquid accumulation bucket is provided with a first wedge surface. The calibration plate is slidably connected to both the support plate and the liquid accumulation bucket; One end of the driving plate sequentially passes through the support plate and the barrel wall of the liquid accumulation bucket. One end of the driving plate located inside the liquid accumulation bucket is provided with a second wedge surface, and the second wedge surface abuts against the outer wall of the friction member. The driving plate is slidably connected to both the support plate and the liquid accumulation bucket; A support frame is fixedly provided on the support plate. The first telescopic rod and the second telescopic rod are both fixedly provided on the support frame. The extending end of the first telescopic rod is fixedly connected to the end of the calibration plate away from the liquid accumulation bucket. The extending end of the second telescopic rod is fixedly connected to the end of the driving plate away from the liquid accumulation bucket. And the tail end of the first telescopic rod is in transmission connection with the tail end of the second telescopic rod. When the lifting member drives the friction member to move downward, the extending end of the second telescopic rod will be compressed, and then the extending end of the first telescopic rod will push out the calibration plate to support the alloy material sample.

[0025] By adopting the above technical solution, the purpose of the provided calibration member is to distinguish the wear amount between the alloy material sample for detection and the friction matrix. The conventional detection method is to measure the two separately, and it cannot intuitively display the wear amount and wear thickness of the two. The provided calibration member is equivalent to setting a reference benchmark. When the lifting member drives the friction member to slide downward, the calibration plate synchronously 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 in the liquid display tube when the motor stops, the thickness of the boronized layer can be intuitively detected, and at the same time, the wear difference between the boronized layer of the alloy material and the friction matrix can be distinguished, significantly improving the evaluation effect of the wear resistance of the alloy material; In addition, when the lifting member drives the friction member to move downward, the second telescopic rod is compressed, and then the first telescopic rod is pushed 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 detection results, ensures the standardization of the detection process, and improves the accuracy and reliability of the detection.

[0026] Preferably, the heating element includes a turntable, a driving gear, a driven gear, and magnetic blocks. A rotating portion is fixedly provided on the turntable. The rotating portion is respectively rotatably connected to the liquid accumulation barrel and the mounting seat. The driving end of the lifting member sequentially passes through the mounting seat, the rotating portion, and the turntable and is fixedly connected to the friction member. The rotating portion is slidably connected to the driving end of the lifting member. The driven gear is fixedly sleeved on the rotating portion. The driving gear is fixedly connected to the output end of the motor. The driving gear meshes with the driven gear. A plurality of groups of magnetic blocks are provided. 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 blocks.

[0027] By adopting the above technical solution, the structure of the turntable and the magnetic blocks is set. Utilizing the characteristic that the electromagnetic induction principle can quickly heat the conductor, the alloy material can be heated to the preset temperature in a short time, while ensuring a uniform temperature distribution on the surface and inside of the alloy material sample during the entire friction test, thereby providing more accurate wear resistance test results, not only improving the detection efficiency, but also making the entire test process more compact and reducing the waiting time; in addition, the transmission system of the driving 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, easily controlling the heating temperature of the sample. Making the conductor heated by the electromagnetic induction principle enables the heating effect to be flexibly adjusted according to different material characteristics, adapting to the test requirements of different alloy materials.

[0028] Preferably, two sets of the turning rods and the connecting rods are provided, and the two sets of the turning rods and the connecting rods are symmetrically arranged along the width direction of the bearing plate. An elastic telescopic rod is provided on the turning rod. One end of the elastic telescopic rod is rotatably connected to the turning rod, and the other end of the elastic telescopic rod is rotatably connected to the mounting plate. When the abutting plate presses the alloy material sample against the friction member, the elastic telescopic rod can limit the rotation of the turning rod to ensure full contact between the alloy material sample and the friction member.

[0029] By adopting the above technical solution, setting two sets of the turning rods and the connecting rods and arranging them symmetrically improves the uniformity of the pressure application, effectively improves the stability of the rotating plate, avoids errors caused by uneven stress on the sample, and ensures that the pressing member and the loading member can stably act on the alloy material sample; the provided elastic telescopic rod can ensure that during the entire detection process, the abutting plate can always press the sample against the friction member, making the sample fully contact with the friction member, and can reduce the interference of the vibration generated during the pressure application and friction processes on the detection results. The stable pressure application state and frictional force can more truly reflect the wear resistance of the alloy material.

[0030] On the other hand, the present application provides a testing process for alloy material wear resistance testing equipment, comprising the following steps:

[0031] S1. Lift the end of the lever away from the mounting plate. The lifting member lifts the friction base into place. The alloy material sample is mounted on the slide through the mounting hole. The lever is then lowered to press the abutment plate against the alloy material sample. The pressure pump is started, and silver nitrate solution flows out of the nozzle.

[0032] S2. Start the motor to rotate, and the transmission crankshaft drives the alloy material sample to rub against the friction substrate. 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. The impact block continuously applies impact pressure to the alloy material sample.

[0033] S3. The color sensor detects that the silver nitrate solution flowing through the alloy material sample has turned black. The motor stops rotating and records the change in the hydraulic oil level in the liquid display tube. The lifting member drives the friction base downward, and the calibration plate extends to support the alloy material sample. The change in the hydraulic oil level in the liquid display tube is recorded again.

[0034] 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.

[0035] In summary, the present application includes at least one of the following beneficial technical effects:

[0036] 1. The hydraulic cylinder, holding rod and holding spring are provided so that the alloy material sample can be uniformly stressed during the test. 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 test, but also intuitively display the wear thickness of the alloy material sample after the test is completed. Conventional wear thickness measurement requires additional testing equipment, and the transfer of alloy material samples is involved in this process, which invisibly increases data errors and also increases the test cost. However, the above technical solution, by utilizing Pascal's principle, can intuitively detect the thickness of the boride layer without additional testing equipment, effectively reducing the cost of testing, reducing unnecessary measurement errors, simplifying the operation process, and significantly improving the evaluation effect of the wear resistance of alloy materials.

[0037] 2. Components such as the impact cylinder, impact rod, load crankshaft, bevel gear, and transmission rod are set up to enable the device to apply dynamic loads to the alloy material sample, thereby simulating the periodic impacts and variable loads that the alloy material withstands in the actual usage environment. This 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 accurately detect the wear resistance of different materials under different load conditions. This dynamic load is more representative than the conventional dynamic pressure application method, making the test results closer to the actual working conditions, thus improving the accuracy of the detection;

[0038] 3. The purpose of setting the calibration part is to distinguish the wear amount between the alloy material sample used for detection and the friction matrix. The conventional detection method is to measure them separately, which cannot intuitively display the wear amount and wear thickness of the two. The set calibration part is equivalent to setting a reference benchmark. When the lifting part drives the friction part to slide downwards, the calibration plate synchronously 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 in the liquid display tube when the motor stops, the thickness of the boride layer can be intuitively detected, and at the same time, the wear difference between the boronized layer of the alloy material and the friction matrix can be distinguished, significantly improving the evaluation effect of the wear resistance of the alloy material; In addition, when the lifting part drives the friction part to move downwards, the second telescopic rod is compressed, and then the first telescopic rod is pushed out to make the calibration plate support the alloy material sample. This linkage setting avoids the errors that may be introduced by manual operation, and 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;

[0039] 4. The set nozzle and multiple groups of nozzles ensure that the silver nitrate solution can be evenly sprayed on the friction substrate and the alloy material sample during the test. This not only simulates the working conditions of the alloy material in a humid environment, but also helps to detect the wear resistance of the material in a corrosive environment through the penetration of the solution and the friction process. The design of multiple groups of nozzles increases the coverage range 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, using silver nitrate solution as the detection medium can produce a color change (such as turning black) through a chemical reaction when it rubs against the alloy material sample. This provides an intuitive visual signal for the detection. Compared with the conventional method of measuring the sample after a specified time or a specified number of friction times, this can not only effectively judge the wear degree and time of the sample under friction and corrosion conditions, avoid relying on complex instrument detection, simplify the operation process, but also accurately detect the thickness of the boride layer on the sample while detecting the wear resistance; In addition, the set color sensor can timely prompt that the sample has reached the critical state of wear, avoiding over-friction or damage to the sample, and ensuring the accuracy of the detection results.

Detailed implementation mode

[0051] The following is a further detailed description of this application in conjunction with the attached Figures 1-7 drawings.

[0052] The embodiment of this application discloses a wear - resistance detection device for alloy materials.

[0053] Referring to Figure 1 and Figure 2 , the wear - resistance detection device for alloy materials includes a mounting component 1, a driving component 2, a friction component 3, and a load component 4. The driving component 2, the friction component 3, and the load component 4 are all mounted on the mounting component 1. The driving component 2 is located below the friction component 3, and the load component 4 is located above the friction component 3. The mounting component 1 is both the installation foundation of the entire detection device and a fixing mechanism for fixing the alloy material sample to be detected; the driving component 2 is the power core of the entire detection device, which can not only drive the friction movement between the alloy material sample to be detected and the friction component 3, but also drive the load component 4 while the alloy material sample to be detected is moving; the friction component 3 is the actual acting mechanism for carrying out wear resistance detection, and can also simulate a specific high - temperature environment; the load component 4 can apply different dynamic loads to the alloy material sample to be detected while it is moving.

The magnetic blocks 344 are embedded on the turntable 341, and the magnetic poles of two adjacent magnetic blocks 344 on the turntable 341 are opposite. When the motor 21 drives the turntable 341 to rotate, since the alloy material sample is a conductor, according to the electromagnetic induction principle, eddy currents will be generated in the conductor in an alternating magnetic field, so joule heat will be generated in the conductor, thereby realizing the heating of the alloy material sample, and thus simulating the wear resistance detection of the alloy material in a high-temperature environment.

One end of the driving plate 352 sequentially passes through the support plate 113 and the barrel wall of the liquid accumulation barrel 31. A second wedge surface 3521 is provided at one end of the driving plate 352 located inside the liquid accumulation barrel 31, and the second wedge surface 3521 abuts against the outer side wall of the friction base 321.

When the jacking member 33 drives the friction base 321 to move upward, under the action of the return spring 355, the extending end of the first telescopic rod 353 drives the calibration plate 351 to retract.

[0066] The nozzle 36 is fixedly arranged on the liquid accumulation barrel 31, and the nozzle 36 is located above one side of the friction base material 322 in the width direction.

[0067] When the color sensor 39 detects that the color of the silver nitrate solution flowing from the alloy material sample turns black, the controller 24 controls the motor 21 to stop rotating, and at the same time the controller 24 controls the pressure pump 38 to close. This means that the boronized layer on the surface of the alloy material has been worn off, and the base material inside the alloy material reacts chemically with the silver nitrate solution, causing the flowing silver nitrate solution to turn black.

[0068] Certainly, in other embodiments of the present application, the lifting member 33 can also be set as an electric push rod, as long as it is a linear driving member that can drive the friction base 321 to move in the vertical direction.

The pressing member 42 includes a hydraulic cylinder 421, a pressing rod 422, a pressing spring 424 and a liquid display tube 423. A vertical plate 123 is fixedly arranged on the bearing plate 12. One end of the rotating plate 41 is rotatably connected to the end of the vertical plate 123 away from the bearing plate 12. The turning rod 44 is arranged above the rotating plate 41.

When the abutting plate 43 presses the alloy material sample against the friction member 32, the elastic telescopic rod 47 can limit the rotation of the turning rod 44 to ensure full contact between the alloy material sample and the friction member 32.

[0070] There are two sets of pressing members 42, and the two sets of pressing members 42 are symmetrically arranged along the length direction of the rotating plate 41. The hydraulic cylinder 421 is fixedly arranged on the rotating plate 41. The abutting rod 422 is coaxially and slidably penetrated through the hydraulic cylinder 421. A piston block 4221 is fixedly arranged on the abutting rod 422. The piston block 4221 is located inside the hydraulic cylinder 421. The piston block 4221 divides the hydraulic cylinder 421 into two independent chambers, namely a pressing chamber 4211 and an adjusting chamber 4212. The pressing chamber 4211 is located at one end of the hydraulic cylinder 421 close to the rotating plate 41, and the pressing chamber 4211 is filled with hydraulic oil; one end of the abutting rod 422 is fixedly connected to the abutting plate 43, and an anti-disengagement portion 4222 is fixedly arranged at the other end of the abutting rod 422. The abutting spring 424 is sleeved on the abutting rod 422. One end of the abutting spring 424 is fixedly connected to the end of the hydraulic cylinder 421 away from the rotating plate 41, and the other end of the abutting spring 424 is fixedly connected to the anti-disengagement portion 4222. The liquid display pipe 423 is fixedly arranged on the hydraulic cylinder 421, and one end of the liquid display pipe 423 is communicated with the pressing chamber 4211. The diameter of the liquid display pipe 423 is much smaller than the diameter of the hydraulic cylinder 421, and the length of the liquid display pipe 423 is greater than the length of the pressing chamber 4211. The two sets of liquid display pipes 423 are connected in parallel.

[0071] Therefore, by turning the turning rod 44, the rotating plate 41 can be driven to rotate, so as to control the abutting of the abutting plate 43 against one end of the alloy material sample. At the same time, according to Pascal's principle, in a connected pipeline, the pressure of the fluid at the same height is the same. Since the diameter of the liquid display pipe 423 is much smaller than the diameter of the hydraulic cylinder 421, a small change in the liquid level of the hydraulic oil in the hydraulic cylinder 421 will cause a relatively large change in the liquid level of the fluid in the liquid display pipe 423, so as to "amplify" and show the small change in the hydraulic cylinder 421.

[0072] The load member 46 includes an impact cylinder 461, a load crankshaft 462, an impact rod 463, a driving bevel gear 464, a driven bevel gear 465 and a transmission rod 466. The impact cylinder 461 is fixedly arranged on the rotating plate 41. The impact cylinder 461 is located between the two sets of hydraulic cylinders 421, and the impact cylinder 461 is arranged in parallel with the hydraulic cylinder 421. An impact block 4611 is slidably arranged in the impact cylinder 461, and hydraulic oil is hermetically injected into the impact cylinder 461. A rotating seat 441 is fixedly arranged on the turning rod 44. Since there are two sets of turning rods 44, there are also two sets of rotating seats 441. One end of the load crankshaft 462 is rotatably connected to the rotating seat 441. The load crankshaft 462 is rotatably mounted on the turning rod 44 through the rotating seat 441. One end of the impact rod 463 is rotatably connected to the load crankshaft 462, and the other end of the impact rod 463 is rotatably connected to the impact block 4611.

[0073] The driving bevel gear 464 is arranged at the end of the connecting shaft 253 away from the bearing plate 12, the driving bevel gear 464 is fixedly connected to the connecting shaft 253, and a rotating shaft 4651 is coaxially fixed to one end of the driven bevel gear 465. The driven bevel gear 465 is rotatably set on the dial rod 44 through the rotating shaft 4651, and the driving bevel gear 464 is meshed with the driven bevel gear 465. One end of the transmission rod 466 is rotatably connected to the end of the driven bevel gear 465 away from the rotating shaft 4651, and the other end of the transmission rod 466 is rotatably connected to the load crankshaft 462. The transmission crankshaft 22 is meshed with the driven bevel gear 465 through the driving bevel gear 464, 465, so that the load crankshaft 462 rotates, thereby causing the impact block 4611 to slide back and forth in the impact cylinder 461, thereby realizing the application of periodic load to the alloy material sample.

[0074] The implementation principle of the alloy material wear resistance testing device of the embodiment of the present application is as follows: lift the end of the dial rod 44 away from the mounting plate 11, and the lifting member 33 lifts the friction base 321 into place. The alloy material sample is installed on the slide 13 through the mounting hole 131, and then the dial rod 44 is lowered to press the abutment plate 43 against the alloy material sample, and the pressure pump 38 is started, and the silver nitrate solution flows out of the nozzle 361; the motor 21 is started to rotate, and the transmission crankshaft 22 drives the alloy material sample and the friction substrate 322 to rub against each other, and at the same time the turntable 341 rotates to heat the alloy material. The locking plate 251 drives the rotating shaft 2522 to rotate, and the driven bevel gear 465 drives the load crankshaft 462 to rotate through the transmission rod 466, and the impact block 4611 continuously applies impact pressure to the alloy material sample; when the color sensor 39 detects that the color of the silver nitrate solution flowing through the alloy material sample turns black, the motor 21 stops rotating, and the liquid level change of the hydraulic oil in the liquid display tube 423 is recorded. The lifting member 33 drives the friction base 321 to move downward, and the calibration plate 351 extends to support the alloy material sample, and the liquid level change of the hydraulic oil in the liquid display tube 423 is recorded once.

The locking disc 251 drives the rotating shaft 2522 to rotate, and the driven bevel gear 465 drives the load crankshaft 462 to rotate through the transmission rod 466. The impact block 4611 continuously exerts impact pressure on the alloy material sample;
