[0036] Embodiment 1

[0037] Figure 1 This is a flowchart of a wear test method provided in the first embodiment of the present invention. This embodiment can be applied to obtain wear test results based on the changes in weight and profile of wear-resistant parts before and after wear. The method can be executed by the wear test device in any embodiment of the present invention. The wear test device can be implemented in the form of hardware and / or software. The wear test device can be configured in an electronic device, typically, in a wear test platform, or in a control terminal device that is connected to the wear test platform. Figure 1 As shown, the method includes:

[0038] S101, obtaining a wear test parameter set; wherein the wear test parameter set includes a plurality of wear test parameters; the wear test parameters include load, hardness ratio, test time, test speed and test stroke.

[0039] First of all, before the wear test of wear-resistant parts, it is usually necessary to clean the wear-resistant parts to be tested to remove impurities such as oil and dust attached to the surface of the wear-resistant parts; the wear test platform can issue cleaning prompts to the testers through voice broadcasts to guide the testers to perform cleaning operations on the wear-resistant parts with the help of corresponding cleaning tools; it can also issue cleaning instructions to automatic cleaning equipment (for example, ultrasonic cleaning equipment) to enable the automatic cleaning equipment to complete the automatic cleaning of dirt on the surface of the wear-resistant parts, so as to avoid impurities on the surface of the wear-resistant parts causing deviations in the wear test results; among them, ultrasonic cleaning equipment can clean dirt on the surface of the wear-resistant parts by high-frequency vibration.

[0040] Secondly, the wear-resistant parts need to be weighed and three-dimensionally scanned to record the weight information and contour information; the wear test platform can send weighing and scanning prompts to the tester through voice broadcast to guide the tester to weigh the wear-resistant parts with the help of an electronic balance, and scan the wear-resistant parts with the help of a three-dimensional scanner, and record the weight information (i.e., the original weight before wear) and the three-dimensional model entered by the tester, and the three-dimensional model reflects the contour information of the wear-resistant parts (i.e., the original contour before wear); the wear-resistant parts can also be placed in the positions of the electronic balance and the three-dimensional scanner in turn by clamping the robotic arm, and the original weight and original contour can be recorded synchronously, so as to complete automatic weighing and automatic scanning.

[0041] Then, the wear-resistant parts need to be placed in the fixture of the wear test platform and reinforced with fasteners such as bolts and clamps to ensure that the wear-resistant parts will not loosen or shift during the entire wear test process. At the same time, during the fixing process, the wear-resistant parts are in close contact with the fixture and remain horizontal to simulate the stress state in the actual working environment; the wear test platform can also issue tightening prompts to the testers through voice broadcasts to guide the testers to complete the manual fixing operation; the wear-resistant parts can also be placed on the fixture through the above-mentioned clamping robot arm to complete automatic fixing.

[0042] Thirdly, the wear test platform also includes a sandbox, and the above-mentioned fixture itself is placed at the bottom of the sandbox. Materials used for wear are placed in the sandbox, such as standard sand, machine-made sand or other materials actually used on the engineering site. The height of the material needs to completely cover the wear-resistant parts, and usually needs to be more than 5 times the particle size of the material, and a counterweight is added on the top of the material to ensure that the material is evenly distributed; the load amount is the total weight of the material and the counterweight, and the material weight is a fixed value.

[0043] Since the sandbox is a rectangular box of standard shape, and the compaction effect of the counterweight makes the material evenly distributed, the overall length and width of the materials piled in the sandbox are fixed values. When the stacking height is preset, and under the premise that the weight of the material remains unchanged, the material height is different under the compaction effect of different weight counterweights. The heavier the counterweight, the higher the material is compacted, and the greater the material density; the lighter the counterweight, the lower the material is compacted, and the lower the material density; and different material densities have different wear forces on wear-resistant parts. The greater the material density, the greater the wear force on wear-resistant parts; the smaller the material density, the smaller the wear force on wear-resistant parts.

[0044] Therefore, under the premise that the weight of the material remains unchanged, the load capacity of the sandbox can be changed by changing the weight of the counterweight; in addition, the overload ratio refers to the ratio of the weight of the counterweight to the weight of the material. Since the weight of the material is a fixed value, changing the weight of the counterweight means changing the overload ratio of the wear test; in particular, the material density in the above technical solution does not refer to the material density of the material itself, but refers to the calculation result of dividing the weight of the material in the sandbox by the volume of the material; the hardness ratio refers to the ratio of the hardness of the wear-resistant part to the hardness of the material, and the hardness of the wear-resistant part and the hardness of the material can be directly obtained according to their respective materials.

[0045] In addition, during the testing of wear-resistant parts, it is necessary to use a transmission system (for example, a hydraulic cylinder transmission system) to drive the fixture and wear-resistant parts to move in the material, and configure its output pressure and output frequency according to the working parameters in the actual working environment so that the wear-resistant parts can reach the specified moving speed (that is, the test speed), and the wear-resistant parts can move at a uniform speed; at the same time, the traditional system drives the wear-resistant parts to perform reciprocating relative motion, and the test stroke refers to the stroke of a single reciprocating relative motion, that is, the moving distance of a single reciprocating relative motion; the test time refers to the testing time of the wear-resistant parts in the sandbox, that is, the total time spent on performing the above-mentioned multiple reciprocating relative motions.

[0046] S102. According to the wear test parameter set, the wear-resistant parts are driven to move back and forth relative to each other in the sand box by the hydraulic cylinder transmission system, so that the materials in the sand box wear the wear-resistant parts.

[0047] As described in the above technical solution, the weight of the counterweight determines the load capacity, and also determines the material height and material density in the sand box; the type of material configured in the sand box and the hardness of the wear-resistant parts determine the hardness ratio; the test speed and test stroke determine the output pressure and output frequency of the transmission system; therefore, based on the above wear test parameters, the wear-resistant parts are driven to reciprocate relative motion in the sand box through the transmission system, so that the materials in the sand box wear the wear-resistant parts.

[0048] S103: Obtain a wear test result of the first wear-resistant part according to the original weight and original profile of the first wear-resistant part before wear, and the remaining weight and remaining profile after wear.

[0049] As described in the above technical solution, after the preset test time, the weight information (i.e., the remaining weight) and contour information (i.e., the remaining contour) after the wear test are obtained again through the above-mentioned weighing and scanning methods, and the wear weight can be obtained through the difference between the original weight and the remaining weight; at the same time, by performing image comparison between the remaining contour and the original contour, the differences in the structure of the wear-resistant parts before and after wear, as well as the distribution of areas with different degrees of wear can be obtained; for example, according to the volume ratio before and after wear, the front area of ​​the first wear-resistant part has a greater degree of wear, and the side area of ​​the first wear-resistant part has a smaller degree of wear.

[0050] In particular, the division of the above-mentioned wear areas can be pre-planned according to the actual structure of the wear-resistant parts. For example, the wear-resistant parts are composed of three components. The above-mentioned three components can be respectively regarded as different areas, and the wear degrees of the above-mentioned different areas are calculated. It is also possible not to pre-classify the structures of the wear-resistant parts, but to divide the areas according to the actual wear degrees. Obviously, the wear degrees of a wear area and its surrounding areas are different, thereby the distribution results of the wear areas of the wear-resistant parts can be obtained.

[0051] The service life of wear-resistant parts can be predicted based on the above-mentioned wear weight and regional wear degree; for example, when the wear weight is greater than the first weight threshold, or the ratio of the wear weight to the original weight is greater than or equal to the first ratio threshold, it indicates that the wear-resistant parts can no longer bear the use requirements of the engineering machinery. The time required for the wear weight to be greater than the first weight threshold can be obtained based on the current wear weight and the wear test time, which can be used as the predicted value of the service life of the wear-resistant parts.

[0052] At the same time, when the degree of wear of any area of ​​the wear-resistant part is greater than the second proportional value that matches it, it means that the area of ​​the wear-resistant part can no longer bear the use requirements of the engineering machinery, that is, it means that the wear-resistant part can no longer bear the use requirements of the engineering machinery; wherein different areas correspond to different second proportional values; thereby, the time required for the degree of wear to be greater than the second proportional value can be obtained based on the current degree of wear and the wear test time, so as to predict the service life of the wear-resistant part; in addition, for one or more areas with a lower service life, design tips and maintenance tips can also be given so that the original structure of the area can be reinforced during design or maintenance to ensure the targeted design and maintenance of the wear-resistant parts.

[0053] Optionally, in an embodiment of the present invention, according to the wear test parameter set, the first wear-resistant part is driven to move reciprocatingly relative to each other in the sandbox through a transmission system so that the material in the sandbox wears the first wear-resistant part, including: issuing a material change prompt according to a sampling interval to guide the sandbox to change materials, and obtaining the intermediate weight and intermediate profile of the first wear-resistant part at the current sampling moment; according to the original weight and original profile of the first wear-resistant part before wear, and the remaining weight and remaining profile after wear, obtaining the wear test result of the first wear-resistant part, including: obtaining the wear test result of the first wear-resistant part according to the original weight and original profile of the first wear-resistant part before wear, the intermediate weight and intermediate profile at each sampling moment, and the remaining weight and remaining profile after wear.

[0054] Specifically, after the wear-resistant parts and materials have been rubbed against each other for a long time, the materials will also be worn, and the friction effect on the wear-resistant parts will also be reduced. During the wear test, a material replacement prompt can be issued according to the preset sampling interval time to guide the sandbox to automatically complete the material replacement or guide the tester to manually complete the material replacement. While the material is replaced, the weight information (i.e., the intermediate weight) and contour information (i.e., the intermediate contour) at the current sampling time are synchronously obtained through the above-mentioned weighing and scanning methods; for example, the total wear test duration can be set to 20 hours, and the sampling interval can be set to 5 hours, that is, the intermediate weight and intermediate contour can be obtained at 5 hours, 10 hours and 15 hours respectively; obviously, the original weight and original contour can also be obtained at 0 hours; the remaining weight and remaining contour can be obtained at 20 hours.

[0055] According to the original weight, remaining weight and each intermediate weight, the weight change curve of the wear-resistant parts can be obtained, thereby knowing the weight change trend of the wear-resistant parts; at the same time, according to the original contour, remaining contour and each intermediate contour, the contour change trend of the wear-resistant parts under different wear time and the wear degree change trend of each wear area can be obtained, so as to obtain more comprehensive test results of the wear-resistant parts and provide more accurate test data for the design and maintenance of wear-resistant parts.

[0056] Optionally, in an embodiment of the present invention, the wear testing method further includes: numerically updating at least one wear test parameter in the wear test parameter set, and obtaining wear test results of a second wear-resistant part of the same type based on the wear test parameter set after the numerical update; and obtaining wear test results of the current type of wear-resistant part under different wear test parameters based on the wear test results of the first wear-resistant part and the wear test results of the second wear-resistant part.

[0057] Specifically, different wear-resistant parts of the same type can be tested under different values ​​of wear test parameters to obtain wear test results of the wear-resistant parts of this type under different wear test parameters; wherein, under different load amounts, the degree of wear of the wear-resistant parts by the material is different, and the greater the load amount, the greater the degree of wear of the wear-resistant parts, that is, the greater the overload ratio, the greater the degree of wear of the wear-resistant parts; for example, the overload ratios can be configured to 1.5, 2, 2.5 and 3, respectively, to obtain the wear test results of the first wear-resistant part and the second wear-resistant part under different overload ratios, respectively, to obtain the wear results of the current type of wear-resistant parts under different load amounts.

[0058] The greater the hardness of the material, the greater the degree of wear on the wear-resistant parts, that is, the smaller the hardness ratio, the greater the degree of wear of the material on the wear-resistant parts; when the materials are mudstone crushed stone, sandstone crushed stone, granite crushed stone and basalt crushed stone, the hardness ratios of the wear-resistant parts to the above materials can be 1.5, 3, 4.5 and 6 respectively; in this way, the wear test results of the first wear-resistant part and the second wear-resistant part at different hardness ratios can be obtained respectively, so as to obtain the wear results of materials with different hardness on the current type of wear-resistant parts.

[0059] The test time, test speed and test stroke are all positively correlated with the degree of wear. The larger the values ​​of the above wear test parameters are, the greater the degree of wear of the wear-resistant parts. For example, the test speeds can be set to 0.1 m / s, 0.2 m / s, 0.3 m / s, 0.4 m / s, 0.5 m / s, 0.6 m / s, 0.7 m / s and 0.8 m / s, respectively, to obtain the wear results of the first wear-resistant part and the second wear-resistant part at different test speeds, respectively. In this way, the wear test results of the current type of wear-resistant parts under different wear test parameters are obtained, so as to guide the operating personnel to reduce one or more wear test parameters with the greatest impact in the working environment, so as to extend the service life of the wear-resistant parts.

[0060] The technical solution of the embodiment of the present invention, after obtaining the wear test parameter set, first drives the first wear-resistant part to reciprocate relative motion in the sandbox through the transmission system according to the wear test parameter set, so that the material in the sandbox wears the first wear-resistant part, and then obtains the wear test result of the first wear-resistant part according to the original weight and original profile of the first wear-resistant part before wear, and the remaining weight and remaining profile after wear. Not only does it realize the test acquisition of wear weight and wear structure under specified wear test parameters, but it also only needs to achieve accurate prediction of the service life of wear-resistant parts in a short test time, avoiding the evaluation error existing in the manual evaluation method, and providing a data basis for the design and maintenance of wear-resistant parts, so as to facilitate the protection design and maintenance of areas with greater wear.

[0061] Embodiment 2

[0062] Figure 2This is a flow chart of a wear test method provided in the second embodiment of the present invention. The relationship between this embodiment and the above embodiment is that different wear-resistant parts are subjected to wear tests in different motion modes. Figure 2 As shown, the method includes:

[0063] S201. Obtain a wear test parameter set; wherein the wear test parameter set includes a plurality of wear test parameters; the wear test parameters include load, hardness ratio, test time, test speed and test stroke.

[0064] S202. According to the wear test parameter set, the first wear-resistant part is driven to perform uniform reciprocating relative motion in the sandbox through the transmission system, and the third wear-resistant part is driven to perform non-uniform reciprocating relative motion in the sandbox; wherein the test speed of the first wear-resistant part is the same as the average test speed of the third wear-resistant part.

[0065] The wear test platform can drive the first wear-resistant part and the third wear-resistant part to perform wear test at the same time through the transmission system, or can perform wear test on the first wear-resistant part and the third wear-resistant part in sequence; the first wear-resistant part moves at a uniform speed in the sandbox, while the third wear-resistant part moves at a non-uniform speed in the sandbox (for example, uniform acceleration motion combined with uniform deceleration motion, or non-uniform variable speed motion), and ensure that the moving speed of the first wear-resistant part is the same as the average moving speed of the third wear-resistant part.

[0066] S203: Obtain a wear test result of the first wear-resistant part according to the original weight and original profile of the first wear-resistant part before wear, and the remaining weight and remaining profile after wear.

[0067] S204: Obtain a wear test result of the third wear-resistant part according to the original weight and original profile of the third wear-resistant part before wear, and the remaining weight and remaining profile after wear.

[0068] S205. Obtain wear test results of the current type of wear-resistant parts under different motion modes according to the wear test results of the first wear-resistant parts and the wear test results of the third wear-resistant parts.

[0069] Therefore, under the premise that the test speed and other wear test parameters are the same, the wear test results of the same wear-resistant parts under different motion modes are obtained, thereby providing a data basis for the influence of different motion modes on the wear of wear-resistant parts. Based on this, the use recommendations of this type of wear-resistant parts in actual engineering environments can be made. For example, under the premise that the values ​​of various wear test parameters are the same, the degree of wear of wear-resistant parts under uniform motion is smaller. It is recommended that the use speed of the wear tool be configured to a uniform motion state in order to extend the service life of the wear-resistant parts.

[0070] The technical solution of the embodiment of the present invention, according to the wear test parameter set, drives the first wear-resistant part to perform uniform reciprocating relative motion in the sandbox through the transmission system, and drives the third wear-resistant part to perform non-uniform reciprocating relative motion in the sandbox, and finally obtains the wear test results of the current type of wear-resistant part under different motion modes according to the wear test results of the first wear-resistant part and the wear test results of the third wear-resistant part. Therefore, under the premise that the parameter values ​​of various wear test parameters are the same, the wear test results of the same wear-resistant part under different motion modes are obtained, thereby providing a data basis for the wear degree of the current type of wear-resistant part under different motion modes, and then issuing usage recommendations for this type of wear-resistant part in actual engineering environments.

[0071] Embodiment 3

[0072] Figure 3 This is a flowchart of a wear test method provided in Embodiment 3 of the present invention. The relationship between this embodiment and the above embodiments is that the wear type of the first wear-resistant part is determined according to the wear grooves of the first wear-resistant part; wherein the wear grooves may include grooves generated by grinding, scratching, and abrasions. Figure 3 As shown, the method includes:

[0073] S301, obtaining a wear test parameter set; wherein the wear test parameter set includes a plurality of wear test parameters; the wear test parameters include load, hardness ratio, test time, test speed and test stroke.

[0074] S302. According to the wear test parameter set, the first wear-resistant part is driven to move back and forth relative to each other in the sandbox through the transmission system, so that the material in the sandbox wears the first wear-resistant part.

[0075] S303: Acquire the wear groove of the first wear-resistant part according to the original profile and the remaining profile of the first wear-resistant part.

[0076] Abrasive wear refers to the formation of grooves with a certain depth on the surface of the wear-resistant part when the material contacts the wear-resistant part. This type of non-uniform wear is called abrasive wear; adhesive wear refers to the relatively uniform wear of the wear-resistant part when the material contacts the wear-resistant part. Although small scratches may appear, no deep grooves will appear. This type of uniform wear is called adhesive wear. After obtaining the original contour and the remaining contour of the first wear-resistant part, various wear grooves on the surface of the first wear-resistant part can be obtained through image comparison; for example, the grooves with a depth exceeding the first depth threshold are regarded as wear grooves, or the grooves with a depth exceeding the first percentage threshold of the thickness of the area are regarded as wear grooves.

[0077] S304. Obtain the wear type of the first wear-resistant part according to the proportion of the wear groove in the remaining profile; wherein the wear type includes adhesive wear and abrasive wear.

[0078] If the ratio of all wear grooves in the remaining contour is greater than the second ratio threshold, it indicates that the grooves formed on the surface of the wear-resistant part cover a large area and the wear mode is mainly caused by non-uniform abrasive wear. At this time, the area where the wear grooves are located can be marked and relevant protection prompts can be issued.

[0082] S401, obtaining a wear test parameter set; wherein the wear test parameter set includes a plurality of wear test parameters; the wear test parameters include load, hardness ratio, test time, test speed and test stroke.

[0083] S402. According to the wear test parameter set, the first wear-resistant part is driven to move back and forth relative to each other in the sandbox through the transmission system, so that the material in the sandbox wears the first wear-resistant part.

[0084] S403: Obtain the wear weight according to the original weight and the remaining weight of the first wear-resistant part.

[0085] S404: Obtain a wear coefficient according to the wear weight and the wear test parameter set.

[0086] The wear weight is related to the above wear test parameters, namely, load, hardness ratio, test time, test speed and test stroke, and is also related to the wear coefficient. The above wear test parameters are all known values, and the wear weight can also be obtained according to the test results. Specifically, the wear coefficient can be calculated according to the following equation (i.e., equation 1):

[0087] W=K*P*L*V*t*H n ; (Equation 1)

[0088] Among them, W is the wear mass, K is the wear coefficient, P is the load, L is the test stroke, V is the test speed, t is the test time, H is the hardness ratio, and n is the fixed coefficient; among them, n is pre-assigned based on the operator's experience.

[0089] S405: Obtain predicted wear weight of the first wear-resistant part under different wear test parameters according to the wear coefficient.

[0090] After obtaining the wear coefficient based on the wear test results, the predicted wear weight under the specified wear test parameters can be calculated according to the above equation, thereby achieving the acquisition of the predicted wear weight of the current type of wear-resistant parts under different wear test parameters.

[0091] The technical solution of the embodiment of the present invention, after obtaining the wear test result of the first wear-resistant part, first obtains the wear weight according to the original weight and the residual weight of the first wear-resistant part, then obtains the wear coefficient according to the wear weight and the wear test parameter set; finally, obtains the predicted wear weight of the first wear-resistant part under different wear test parameters according to the wear coefficient. In this way, the predicted wear weight of the current type of wear-resistant part under different wear test parameters is obtained, and the wear instruction prediction range of the current type of wear-resistant part is expanded to apply to different operating conditions.
