Description

Technical Field

[0001] The present invention relates to the technical field of detecting the torsional strength of a high-entropy alloy bar, and in particular to a device and method for efficiently detecting the torsional strength of a high-entropy alloy bar. Background Art

[0002] The structure of the high entropy alloy rod 1 produced in a certain workshop is as follows Figure 1~Figure 2 As shown, the cross-section of the high-entropy alloy rod 1 is square and its total length is 50 cm. The production process of this high-entropy alloy rod 1 is: first, the high-entropy alloy is pressed into a semi-finished product by a pressing machine, and then the semi-finished product is sintered by a sintering equipment, thereby finally producing the high-entropy alloy rod 1. This high-entropy alloy rod 1 with high mechanical strength is mainly used to manufacture forging products.

[0003] After 10 high-entropy alloy rods 1 are mass-produced in the workshop, workers will test the torsional strength of all 10 high-entropy alloy rods 1. After all 10 high-entropy alloy rods 1 are tested, if the torsional strength of 2 high-entropy alloy rods does not meet the requirements, the workers will adjust the production process of the high-entropy alloy rods 1; if the torsional strength of all 10 high-entropy alloy rods 1 meets the requirements, the workers will continue to use the original production process to mass-produce a large number of high-entropy alloy rods 1 to provide them to customers.

[0004] Use in workshop Figure 3 The testing machine shown is used to test the torsional strength of the high-entropy alloy rod 1. The testing machine includes a bracket 2 fixed on the base plate, a hydraulic motor A3 fixed on the top wall of the bracket 2, the output shaft of the hydraulic motor A3 passes downward through the top wall of the bracket 2, and a vertical clamping cylinder A4 is fixed on the extended end, and the chuck A5 of the vertical clamping cylinder A4 faces downward; a vertical clamping cylinder B6 is also fixed on the base plate, and the chuck B7 of the vertical clamping cylinder B6 faces upward.

[0005] The method used by workers to test the torsional strength of 10 high entropy alloy bars 1 using the testing machine is: S1. Perform a torsional strength test on the first high-entropy alloy rod 1. The specific steps are as follows: S11, the worker takes out a Figure 1~Figure 2 As shown in the high entropy alloy rod 1, workers stick two double-sided tapes 8 on one end surface of the high entropy alloy rod 1. Figure 4 As shown, ensure that the distance between the lower double-sided tape 8 and the bottom surface of the high-entropy alloy rod 1 is 25 cm, and the distance between the upper double-sided tape 8 and the top surface of the high-entropy alloy rod 1 is 10 cm; S12. The worker sticks an angle sensor 9 on each of the two double-sided adhesive tapes 8 of the high entropy alloy bar 1. Figure 5As shown, the two angle sensors 9 are installed on the high entropy alloy rod 1 [the purpose of sticking the angle sensor 9 to the high entropy alloy rod 1 is to accurately monitor the deformation of the high entropy alloy rod 1]; S13, the worker connects the signal wires of the two angle sensors 9 to the controller; S14: The worker places the upper end of the high entropy alloy rod 1 into the chuck A5 of the vertical clamping cylinder A4. Figure 6 As shown, the lower end of the high entropy alloy rod 1 is placed into the chuck B7 of the vertical clamping cylinder B6, as shown Figure 6 As shown; S15, control the vertical clamping oil cylinder A4 to start, close the chuck A5 of the vertical clamping oil cylinder A4, and clamp the upper end of the high entropy alloy rod 1 to fix it. Figure 7 As shown; the vertical clamping cylinder B6 is controlled to start, the chuck B7 of the vertical clamping cylinder B6 is closed, and the chuck B7 clamps and fixes the lower end of the high entropy alloy rod 1, as shown Figure 7 As shown; S16, control the hydraulic motor A3 to start, the output shaft of the hydraulic motor A3 drives the vertical clamping cylinder A4 to rotate, and the vertical clamping cylinder A4 drives the upper end of the high entropy alloy rod 1 to rotate. The rotation direction of the upper end of the high entropy alloy rod 1 is as follows: Figure 8 As shown by the middle arrow, the high-entropy alloy rod 1 is gradually twisted and deformed. The twisted and deformed high-entropy alloy rod 1 then drives the two angle sensors 9 on it to rotate synchronously on the horizontal plane. The angle sensors 9 monitor the angle value and transmit it to the controller in real time. When the hydraulic motor A3 works for the set time, the controller controls the hydraulic motor A3 to shut down, and the worker calculates the average of the two angle values ​​transmitted to the controller by the two angle sensors 9. If the calculated average value is less than or equal to the specified deformation value, it means that the torsional strength of the tested high-entropy alloy bar 1 meets the requirements. The worker's next operation is: the worker controls the vertical clamping cylinder A4 and the vertical clamping cylinder B6 to close, and then the worker removes the high-entropy alloy bar 1. After removing it, the worker removes the two angle sensors 9 attached to the high-entropy alloy bar 1; If the calculated average value is greater than the specified deformation value, it means that the torsional strength of the high-entropy alloy bar 1 under test does not meet the requirements. The worker's next operation is: the worker controls the vertical clamping cylinder A4 and the vertical clamping cylinder B6 to close, and then the worker removes the high-entropy alloy bar 1. After removing it, the worker removes the two angle sensors 9 attached to the high-entropy alloy bar 1 to prepare for subsequent testing of the high-entropy alloy bar 1; S2. The worker repeats step S1 nine times, thereby completing the torsional strength test on the remaining nine high-entropy alloy bars 1. S3. After all 10 high-entropy alloy rods 1 are tested, if the torsional strength of two high-entropy alloy rods does not meet the requirements, the worker adjusts the production process of the high-entropy alloy rods 1; if the torsional strength of all 10 high-entropy alloy rods 1 meets the requirements, the worker continues to use the original production process to batch produce a large number of high-entropy alloy rods 1 to provide to customers.

[0006] However, although this testing machine can complete the torsional strength test of 10 high-entropy alloy bars 1, it still has the following technical defects: I. In step S11, a worker is required to stick two double-sided tapes 8 at the specified positions of the high-entropy alloy bar 1. In step S12, a worker is required to stick an angle sensor 9 on each of the two double-sided tapes 8 to install the two angle sensors 9 at the specified positions of the high-entropy alloy bar 1; in step S13, a worker is required to connect the signal lines of the two angle sensors 9 to the controller, and then continue to test the torsional strength of the high-entropy alloy bar 1.

[0007] However, the entire operation is done manually, and there are many operating procedures, which not only increases the work intensity of the workers, but also increases the detection time of the torsional strength of a single high-entropy alloy rod 1, thereby reducing the detection efficiency of the torsional strength of the high-entropy alloy rod 1.

[0008] II. In step S16, after each torsional strength test of a high-entropy alloy bar 1 is completed, workers are required to remove the two angle sensors 9 from the high-entropy alloy bar 1 to prepare for subsequent tests of the high-entropy alloy bar 1. This undoubtedly adds another testing step, thereby increasing the time required to test the torsional strength of subsequent high-entropy alloy bars 1, and further reducing the efficiency of the torsional strength test of the high-entropy alloy bars 1.

[0009] III. This type of testing machine can only test the high-entropy alloy bars 1 one by one, and there are as many as 10 high-entropy alloy bars 1 to be tested in the workshop. As a result, it takes a long time to complete the testing of all 10 high-entropy alloy bars 1, thereby further reducing the testing efficiency of the torsional strength of the high-entropy alloy bars 1, and thus making it impossible for workers to quickly know whether the production process used can be used for mass production of high-entropy alloy bars.

[0010] Therefore, there is an urgent need for a detection device and method that can greatly reduce the workload of workers and greatly improve the efficiency of detecting the torsional strength of high-entropy alloy bars. Summary of the Invention

The piston rods of the two horizontal electric cylinders extend into the rectangular shell, and a U-shaped clamping block is fixedly provided on the extended end thereof. A recess is provided at the bottom of the slot of one of the U-shaped clamping blocks, and an angle sensor is fixedly provided in the recess. The outer end surface of the angle sensor is flush with the slot of the U-shaped clamping block. Two hydraulic motors C are fixed on the top surface of the frame. The two hydraulic motors C are respectively located directly above the two mounting assemblies on the upper layer. The output shafts of the two hydraulic motors C both pass downward through the top wall of the frame, and a vertical clamping cylinder C is fixed on the extended end, with the clamping head C of the vertical clamping cylinder C facing downward.

[0013] The two installation components on the left side of the frame are symmetrical to the two installation components on the right side.

[0014] The longitudinal width of the slot of the U-shaped block is equal to the longitudinal width of the high-entropy alloy rod.

[0015] A wire hole is provided on the top wall of the sink, passing through the top surface of the U-shaped block. The signal line of the angle sensor passes through the wire hole and is electrically connected to the controller.

[0016] The positioning and clamping assembly includes two positioning platforms fixed on the workbench surface and a double-acting oil cylinder fixed on the bottom surface of the workbench. The two positioning platforms are respectively located directly below the two mounting assemblies on the lower layer. Positioning grooves are provided on the top surfaces of the two positioning platforms. The positioning grooves match the outer contour of the high-entropy alloy rod. The outer sides of the two positioning platforms are provided with through grooves opened in the workbench. A movable plate is fixed on the acting end of the two piston rods of the double-acting oil cylinder, and the two movable plates respectively pass through two through slots upward. A horizontal clamping oil cylinder is fixed on the top surface of the two movable plates, and the clamping head of the horizontal clamping oil cylinder is set towards the positioning platform.

[0017] A guide rail fixed on the workbench surface is provided between the through slot and the positioning platform, and a slider is fixed on the movable plate, and the slider is slidably mounted on the guide rail.

[0018] The detection device also includes a controller, which is electrically connected to the lifting cylinder, the double-acting cylinder, the horizontal clamping cylinder, the hydraulic motor C, and the vertical clamping cylinder C.

[0019] A high-efficiency method for detecting the torsional strength of a high-entropy alloy bar comprises the following steps: S1. Positioning two high-entropy alloy bars: A worker takes out two mass-produced high-entropy alloy bars to be tested, and respectively embeds the lower ends of the two high-entropy alloy bars into the positioning grooves of the two positioning platforms of the positioning and clamping assembly. Since the positioning grooves match the outer contours of the high-entropy alloy bars, the positioning of the two high-entropy alloy bars is achieved. At this time, the two high-entropy alloy bars are respectively located directly below the hollow cylinders of the two mounting assemblies on the lower layer. At the same time, the lower ends of the two high-entropy alloy bars are respectively opposite to the chucks of the two horizontal clamping cylinders of the positioning and clamping assembly; S2. The worker controls the piston rods of the two lifting cylinders to retract downward, which drives the frame downward. The frame then drives the two hydraulic motors C, the vertical clamping cylinder C, and the four mounting assemblies to move downward synchronously. The two mounting assemblies on the left side of the frame move toward the high-entropy alloy rod on the left, and the two mounting assemblies on the right side of the frame move toward the high-entropy alloy rod on the right. When the piston rods of the two lifting cylinders are fully retracted, the two high-entropy alloy bars enter the inspection station. The high-entropy alloy bar on the left is inserted into the hollow cylinder and rectangular shell of the two mounting components on the left. At the same time, the high-entropy alloy bar on the right is inserted into the hollow cylinder and rectangular shell of the two mounting components on the right. At the same time, the high-entropy alloy bar is just between the two U-shaped blocks of the mounting components. At the same time, the upper ends of the two high-entropy alloy bars are just in the chucks C of the two vertical clamping cylinders C. S3. Clamping and fixing the upper ends of the two high-entropy alloy bars: Controlling the two vertical clamping cylinders C to start, the chucks C of the vertical clamping cylinders C are closed, and the chucks C clamp and fix the upper ends of the high-entropy alloy bars, thereby achieving the clamping and fixing of the upper ends of the two high-entropy alloy bars; S4. Clamp and fix the lower ends of the two high-entropy alloy bars. The specific operation steps are as follows: S41. Both piston rods of the double-acting oil cylinder controlling the positioning and clamping assembly are retracted inward, and both piston rods drive the movable plate connected thereto to move inward, and the movable plate drives the horizontal clamping oil cylinder to move inward synchronously, wherein the horizontal clamping oil cylinder on the left side moves toward the lower end of the high-entropy alloy rod on the left side, and at the same time, the horizontal clamping oil cylinder on the right side moves toward the lower end of the high-entropy alloy rod on the right side; when the two piston rods of the double-acting oil cylinder are fully retracted, the chuck of the horizontal clamping oil cylinder is just sleeved on the outside of the lower end of the high-entropy alloy rod; S42, controlling the two horizontal clamping cylinders to start, closing the chucks of the horizontal clamping cylinders, and clamping and fixing the lower ends of the high-entropy alloy bars, thereby clamping and fixing the lower ends of the two high-entropy alloy bars; S5. Install two angle sensors at designated locations on the two high-entropy alloy bars. The specific steps are as follows: S51. The worker controls the two horizontal electric cylinders on the left side of the frame to extend. The horizontal electric cylinders drive the U-shaped clamps to move toward the high-entropy alloy rod. When the piston rods of the horizontal electric cylinders are fully extended, the two horizontally opposed U-shaped clamps just hold the high-entropy alloy rod tightly. At the same time, the angle sensors in the U-shaped clamps are just installed on the end faces of the high-entropy alloy rod, thus achieving the installation of two angle sensors at the designated positions on the left high-entropy alloy rod. S52: The worker controls the horizontal electric cylinders of the two mounting assemblies on the right side of the frame to extend, thereby installing two angle sensors at designated locations on the right side of the high-entropy alloy rod. S6. Control both hydraulic motors C to start, and the output shaft of the hydraulic motor C drives the vertical clamping cylinder C to rotate. The vertical clamping cylinder C drives the upper end of the high-entropy alloy rod to rotate, thereby gradually twisting and deforming the high-entropy alloy rod. The twisted and deformed high-entropy alloy rod drives the U-shaped clamping block to rotate synchronously on the horizontal plane. The U-shaped clamping block drives the rectangular shell and the hollow cylinder to rotate synchronously on the horizontal plane. The hollow cylinder drives the annular plate to rotate synchronously on the horizontal plane. The annular plate deforms the torsion spring. At the same time, the U-shaped clamping block also drives the angle sensor to rotate synchronously on the horizontal plane. The angle sensor transmits the monitored angle value to the controller in real time. When the hydraulic motor C works for the set time, the controller controls the hydraulic motor C to shut down, and then the worker calculates the average of the two angle values ​​transmitted to the controller by the two angle sensors; If the calculated average value is less than or equal to the specified deformation value, it means that the torsional strength of the tested high-entropy alloy bar meets the requirements; If the calculated average value is greater than the specified deformation value, it means that the torsional strength of the tested high-entropy alloy rod does not meet the requirements, thus finally completing the torsional strength test of the two high-entropy alloy rods; S7. The worker takes away the two high-entropy alloy bars that have been tested. The specific operation steps are as follows: S71. The horizontal electric cylinder of the control mounting assembly is retracted, and the piston rod drives the U-shaped clamping block to move away from the high-entropy alloy rod. After the U-shaped clamping block is separated from the high-entropy alloy rod, the elastic restoring force of the deformed torsion spring resets the hollow cylinder and the rectangular shell, thereby resetting the angle sensor to its initial position in preparation for subsequent high-entropy alloy rod testing. S72. The worker controls the horizontal clamping cylinder to close so that the chuck of the horizontal clamping cylinder no longer clamps the lower end of the high-entropy alloy rod; then controls the two piston rods of the double-acting cylinder to extend outward, thereby moving the horizontal clamping cylinder away from the high-entropy alloy rod; S73. The worker controls the vertical clamping cylinder C to close, so that the chuck C of the vertical clamping cylinder C no longer clamps the upper end of the high-entropy alloy rod. S74. Control the piston rods of the two lifting cylinders to extend upward, which drive the frame to move upward. The frame then drives the hydraulic motor C and the four mounting assemblies to move upward, so that the mounting assemblies move away from the high-entropy alloy rod. S75. After the four mounting components are reset, the worker removes the two inspected high-entropy alloy bars from the positioning table. S8. The worker repeats steps S1 to S7 four times to complete the torsional strength test on the remaining eight high-entropy alloy bars. S9. After all 10 high-entropy alloy rods are tested, if the torsional strength of 2 high-entropy alloy rods does not meet the requirements, the workers will adjust the production process of the high-entropy alloy rods; if the torsional strength of all 10 high-entropy alloy rods meets the requirements, the workers will continue to use the original production process to batch produce a large number of high-entropy alloy rods for customer use.

[0020] The present invention has the following advantages: greatly reducing the workload of workers and greatly improving the efficiency of testing the torsional strength of high-entropy alloy bars. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A high-efficiency method for detecting the torsional strength of a high-entropy alloy bar comprises the following steps: S1. Positioning two high-entropy alloy bars 1: A worker takes out two mass-produced high-entropy alloy bars 1 to be tested. The structure of the high-entropy alloy bars 1 is as follows: Figure 1~Figure 2 As shown, the lower ends of the two high entropy alloy bars 1 are respectively embedded in the positioning grooves 30 of the two positioning platforms 28 of the positioning and clamping assembly 11.

At the same time, the high entropy alloy rod 1 is just between the two U-shaped blocks 21 of the mounting assembly 14, and at the same time, the upper ends of the two high entropy alloy rods 1 are just in the chucks C26 of the two vertical clamping cylinders C25; S3. Clamp and fix the upper ends of the two high-entropy alloy bars 1: Control the two vertical clamping cylinders C25 to start, and close the chuck C26 of the vertical clamping cylinder C25. The chuck C26 clamps and fixes the upper ends of the high-entropy alloy bars 1, thereby achieving the clamping and fixing of the upper ends of the two high-entropy alloy bars 1. Figure 23 As shown; S4. Clamp and fix the lower ends of the two high-entropy alloy bars 1. The specific operation steps are as follows: S41. The two piston rods of the double-acting oil cylinder 29 of the control positioning and clamping assembly 11 are both retracted inward, and the two piston rods drive the movable plate 32 connected thereto to move inward, and the movable plate 32 drives the horizontal clamping oil cylinder 33 to move inward synchronously, wherein the horizontal clamping oil cylinder 33 on the left side moves toward the lower end direction of the high-entropy alloy rod 1 on the left side, and at the same time, the horizontal clamping oil cylinder 33 on the right side moves toward the lower end direction of the high-entropy alloy rod 1 on the right side; when the two piston rods of the double-acting oil cylinder 29 are fully retracted, the chuck 34 of the horizontal clamping oil cylinder 33 is just sleeved on the outside of the lower end of the high-entropy alloy rod 1, as shown in FIG. Figure 24-25 As shown; S42, control the two horizontal clamping oil cylinders 33 to start, the clamping heads 34 of the horizontal clamping oil cylinders 33 are closed, and the clamping heads 34 clamp and fix the lower end of the high entropy alloy rod 1, as shown in FIG. Figure 26 As shown, the lower ends of the two high entropy alloy bars 1 are clamped and fixed; S5. Install two angle sensors 9 at designated positions of the two high-entropy alloy bars 1. The specific operation steps are as follows: S51. The worker controls the horizontal electric cylinders 20 of the two mounting assemblies 14 on the left side of the frame 13 to extend. The horizontal electric cylinders 20 drive the U-shaped clamping block 21 to move toward the high-entropy alloy rod 1. When the piston rod of the horizontal electric cylinder 20 is fully extended, the two horizontally opposite U-shaped clamping blocks 21 just hold the high-entropy alloy rod 1 tightly. At the same time, the angle sensor 9 in the U-shaped clamping block 21 is just installed on the end face of the high-entropy alloy rod 1. Figures 27 to 29 As shown, two angle sensors 9 are installed at designated positions of the left high-entropy alloy rod 1; S52, the worker controls the horizontal electric cylinders 20 of the two mounting assemblies 14 on the right side of the frame 13 to extend, thereby installing the two angle sensors 9 at the designated positions on the right side of the high-entropy alloy rod 1; Among them, it can be seen in steps S1~S5 that the worker only needs to first position the high-entropy alloy rod 1 to be tested on the positioning platform 28, and then control the piston rods of the two lifting cylinders 12 to retract downward so that the two high-entropy alloy rods 1 enter the detection station, and finally control the horizontal electric cylinder 20 of the installation component 14 to extend, so that the angle sensor 9 can be installed at the specified position of the high-entropy alloy rod 1.

[0029] It can be seen that this detection device is better than Figures 3 to 8 The detection method shown does not require workers to stick two double-sided tapes 8 at the specified position of the high-entropy alloy rod 1, nor does it require workers to stick an angle sensor 9 on both double-sided tapes 8, nor does it require workers to connect the signal lines of the two angle sensors 9 to the controller, so as to detect the torsional strength of the high-entropy alloy rod 1. The present detection device realizes the automatic and rapid installation of the two angle sensors 9 at the specified position of the high-entropy alloy rod 1, which not only greatly reduces the work intensity of the workers, but also saves a large number of detection processes, thereby shortening the detection time of the torsional strength of a single high-entropy alloy rod 1, thereby greatly improving the detection efficiency of the torsional strength of the high-entropy alloy rod 1.

[0030] S6. Control both hydraulic motors C24 to start. The output shaft of the hydraulic motor C24 drives the vertical clamping cylinder C25 to rotate. The vertical clamping cylinder C25 drives the upper end of the high entropy alloy rod 1 to rotate. The rotation direction of the upper end of the high entropy alloy rod 1 is as follows: Figure 30 As shown by the middle arrow, the high-entropy alloy rod 1 is gradually twisted and deformed, and the twisted and deformed high-entropy alloy rod 1 drives the U-shaped block 21 to rotate synchronously on the horizontal plane, and the U-shaped block 21 drives the rectangular shell 19 and the hollow cylinder 16 to rotate synchronously on the horizontal plane, and the hollow cylinder 16 drives the annular plate 17 to rotate synchronously on the horizontal plane, and the annular plate 17 deforms the torsion spring 18. At the same time, the U-shaped block 21 also drives the angle sensor 9 to rotate synchronously on the horizontal plane, and the angle sensor 9 transmits the monitored angle value to the controller in real time; When the hydraulic motor C24 works for the set time, the controller controls the hydraulic motor C24 to turn off, and then the worker calculates the average of the two angle values ​​transmitted to the controller by the two angle sensors 9; If the calculated average value is less than or equal to the specified deformation value, it means that the torsional strength of the tested high-entropy alloy rod 1 meets the requirements; If the calculated average value is greater than the specified deformation value, it means that the torsional strength of the high-entropy alloy rod 1 being tested does not meet the requirements, thereby finally completing the torsional strength test of the two high-entropy alloy rods 1; S7. The worker takes away the two inspected high-entropy alloy bars 1. The specific operation steps are as follows: S71. The horizontal electric cylinder 20 of the control mounting assembly 14 is retracted, and the piston rod drives the U-shaped clamping block 21 to move away from the high-entropy alloy bar 1. After the U-shaped clamping block 21 is separated from the high-entropy alloy bar 1, the elastic restoring force of the deformed torsion spring 18 resets the hollow cylinder 16 and the rectangular shell 19, thereby resetting the angle sensor 9 to its initial position, in preparation for subsequent detection of the high-entropy alloy bar 1. S72. The worker controls the horizontal clamping cylinder 33 to close, so that the chuck 34 of the horizontal clamping cylinder 33 no longer clamps the lower end of the high-entropy alloy rod 1; then controls the two piston rods of the double-acting cylinder 29 to extend outward, thereby moving the horizontal clamping cylinder 33 away from the high-entropy alloy rod 1; S73. The worker controls the vertical clamping cylinder C25 to close, and the chuck C26 of the vertical clamping cylinder C25 no longer clamps the upper end of the high-entropy alloy rod 1. S74. Control the piston rods of the two lifting cylinders 12 to extend upward, which drive the frame 13 to move upward. The frame 13 drives the hydraulic motor C24 and the four mounting assemblies 14 to move upward, so that the mounting assemblies 14 move away from the high-entropy alloy rod 1. S75. After the four mounting assemblies 14 are reset, the worker removes the two high entropy alloy bars 1 that have been tested from the positioning table 28. The direction of removing the two high entropy alloy bars 1 is as follows: Figure 31 As indicated by the arrow; Among them, it can be seen from step S71 that the worker only needs to control the piston rod of the horizontal electric cylinder 20 of the installation component 14 to retract, and after the U-shaped block 21 is separated from the high-entropy alloy bar 1, the angle sensor 9 automatically resets to the initial position under the elastic restoring force of the deformed torsion spring 18, thereby preparing for the subsequent detection of the high-entropy alloy bar 1. It can be seen from this that the detection device is better than the following Figures 3 to 8 The detection method shown does not require workers to tear off the two angle sensors 9 on the high-entropy alloy rod 1 in preparation for subsequent detection of the high-entropy alloy rod 1, further reducing the detection process and thus shortening the detection time of the subsequent high-entropy alloy rod 1 torsional strength, thereby further greatly improving the detection efficiency of the torsional strength of the high-entropy alloy rod 1.

[0031] S8. The worker repeats steps S1 to S7 four times to complete the torsional strength test on the remaining eight high-entropy alloy bars 1. S9. After all 10 high-entropy alloy rods 1 are tested, if the torsional strength of 2 high-entropy alloy rods does not meet the requirements, the workers will adjust the production process of the high-entropy alloy rods 1; if the torsional strength of all 10 high-entropy alloy rods 1 meets the requirements, the workers will continue to use the original production process to batch produce a large number of high-entropy alloy rods 1 to provide to customers.

[0032] Among them, it can be seen from steps S1 to S8 that the present detection device can perform torsional strength detection on two high entropy alloy bars 1 at one time, compared with the Figures 3 to 8 The detection method shown does not require workers to test the high-entropy alloy bars 1 one by one, thereby achieving the completion of the detection of all 10 high-entropy alloy bars 1 in a short period of time, thereby greatly improving the detection efficiency of the torsional strength of the high-entropy alloy bars 1.
