Description

Technical Field

[0001] The present invention relates to the technical field of hardness detection, in particular to a device for detecting the hardness of a finished molybdenum alloy product. Background Art

[0002] Indentation hardness testing is a standardized method for assessing a material's hardness by measuring its ability to resist penetration by an indenter under a specific load. It is widely used to evaluate the mechanical properties of metals, ceramics, and composites. This test typically uses hardness scales such as Vickers (HV), Brinell (HB), or Rockwell (HR). The core principle is to press a geometrically shaped indenter (such as a diamond pyramid or carbide ball) into the specimen surface under specified conditions. The load is maintained for a specified time, then unloaded. The hardness value is calculated by measuring the size or depth of the residual indentation. The testing process must strictly adhere to international standards (such as ISO 6507 and ASTM E384), including control of key parameters such as specimen preparation, testing environment, loading rate, and dwell time. The specimen surface must be polished to ensure the required roughness and avoid surface defects that may affect the test results. The indentation location should avoid material defects or work-hardened areas, and at least multiple valid indentations should be measured on each specimen to obtain a reliable average value. Indentation hardness testing offers high accuracy and repeatability, making it suitable for hardness analysis from macro to micro scales, and is particularly well-suited for testing high-hardness materials such as molybdenum alloys. The test results can be used to evaluate the wear resistance, strength and heat treatment effect of the material, providing key data support for process optimization and quality control.

[0003] Molybdenum alloy products produce debris during indentation hardness testing. Failure to promptly remove this debris can not only affect the accuracy of test results but also damage the hardness testing equipment. If the indenter encounters this hard, brittle debris during the indentation process, it can cause localized stress concentration, accelerated indenter wear, and even micro-cracks, impacting the accuracy of subsequent tests. Especially for high-hardness molybdenum alloys (such as TZM), debris can exacerbate indenter wear and reduce service life. Summary of the Invention

By setting the guide port 57, the molybdenum alloy product to be tested can be guided so that the molybdenum alloy product can be discharged from the movable cover 54 through the guide port 57 after being subjected to an oblique upward thrust. The pressing mechanism 58 includes a connecting ring 581, which is fixedly connected to the lower surface of the movable cover 54.

[0025] The placing mechanism 7 includes a breathable ring 71 and a moving box 72. The breathable ring 71 is fixedly connected between the breathable ring 61 and the parcel box 4. The moving box 72 is movably connected to the lower surface of the breathable ring 61. The bottom surface of the inner cavity of the moving box 72 is fixedly connected to a third spring 78. The top of the third spring 78 is fixedly connected to the lower surface of the breathable ring 61. By providing the breathable ring 71, the air in the inner cavity of the breathable ring 61 can be circulated with the outside. By providing the third spring 78, the moving box 72 can rebound after moving downward. The upper surface of the moving box 72 is fixedly connected to the breathable box 73.

By setting the breathable box 73, it can cooperate with the breathable ring 71 so that the holes of the breathable ring 71 and the holes of the breathable box 73 are aligned. When they are aligned, the air in the inner cavity of the breathable box 73 can circulate due to the suction force in the inner cavity of the breather ring 61, so that the debris generated by the pressing of the molybdenum alloy finished product can be sucked into the inner cavity of the breather ring 61. By setting the support net 74, the bottom of the molybdenum alloy finished product can be supported. By setting the first connecting port 79, the first connecting pipe 710, the telescopic pipe 711, the second connecting pipe 712 and the second connecting port 713, the space in the inner cavity of the movable box 72 can be connected with the movable cover 54. When the breathable box 73 and the breather ring 71 are staggered, suction is generated in the inner cavity of the movable box 72, so that the hot air generated by the pressing of the molybdenum alloy finished product in the inner cavity of the movable cover 54 can be sucked into the inner cavity of the movable cover 54. When the locking cam 77 is in the unlock state, the locking cam 77 is in the unlock state, and the locking cam 77 is in the unlock state, so that the locking cam 77 is locked.

[0026] Working principle: When in use, the operator connects the high-pressure blower 66 to the power supply and turns on the switch, so that the high-pressure blower 66 generates a high-speed airflow in the inner cavity of the exhaust box 63. Then the operator places the molybdenum alloy finished product to be tested on the guide port 57 and pushes it to the upper surface of the support net 74; then the operator connects the pressure feedback cylinder 51 to the power supply and the controller to generate a continuous downward extrusion force. During the extrusion process, the extrusion rod 52 drives the extrusion block 53 to squeeze the extrusion groove 585, thereby rotating the rotating column 583 in the inner cavity of the limiting tube 582, and restores the balance of the pressing plate 584 and squeezes the upper surface of the molybdenum alloy finished product. During the extrusion process, the moving box 72 moves downward. The slag produced by the extrusion of the molybdenum alloy product is sucked into the inner cavity of the vent ring 61 and is finally blocked by the adsorption pad 67. The operator then inserts the positioning rod 77 into the inner cavity of the first positioning frame 75. After the hardness test of the molybdenum alloy product is completed, the pressure feedback cylinder 51 is stopped and the data is recorded. The positioning rod 77 is then pulled out, and the moving box 72 moves upward rapidly under the elastic potential energy stored in the third spring 78, and the molybdenum alloy product on the upper surface of the support net 74 moves upward. Then, under the guidance of the inclined pressing plate 584, the molybdenum alloy product hits the inner cavity of the guide port 57, and the molybdenum alloy product can be taken out.
