Description

Technical Field

[0001] This utility model mainly relates to the technical field of hardness testing devices, specifically a hardness testing device for the production of alloy special materials. Background Technology

[0002] Hardness testing devices for alloy materials are core testing tools in fields such as materials science, mechanical manufacturing, aerospace, and automotive industries. Their core function is to quantify a material's ability to resist localized plastic deformation through indentation methods such as Brinell, Rockwell, and Vickers, or the Shore springback method, directly reflecting mechanical properties such as wear resistance and compressive strength. They also indirectly infer other performance indicators through empirical correlations between hardness and parameters such as tensile strength and fatigue life. Existing hardness testing devices for alloy materials typically have only one indenter and require frequent manual intervention, resulting in low testing efficiency.

[0003] According to application number 202421005330.5, a bonding wire hardness testing device includes an L-shaped plate, an L-shaped plate two fixedly connected to one side of the L-shaped plate, a rotating shaft rotatably connected to the top of the L-shaped plate two, a fixed cylinder threadedly connected to the bottom of the rotating shaft through the L-shaped plate two, two limiting plates fixedly connected to the outside of the fixed cylinder, a pressure head fixedly installed at the bottom of the fixed cylinder, and a pressure gauge fixedly installed at the end of the L-shaped plate two away from the L-shaped plate one. The rotating shaft can drive the fixed cylinder to rotate, and the limiting plates and limiting grooves can ensure the running trajectory of the fixed cylinder. The hardness of the bonding wire can be tested by the cooperation of the pressure head and the pressure gauge.

[0004] The aforementioned document improves the structure for ease of operation, enabling rapid hardness testing without requiring manual operation by employees. However, it lacks diverse testing structures and cannot detect the hardness performance of alloy materials under different ballast structures and ballast forces. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a hardness testing device for the production of alloy special materials, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hardness testing device for alloy special material production includes a control base. Two limiting plates are symmetrically fixedly installed on both sides of the top of the control base. A gantry frame is mounted on the top of the two limiting plates. A support plate is slidably installed on the top of the two limiting plates. Multiple mounting buckles are fixedly installed on the support plate. A measuring component is fixedly installed in the middle of one side of the two limiting plates. Multiple C-shaped plates are fixedly installed on one side of the gantry frame. A spring tube is fixedly installed in the middle of the C-shaped plate. A pressure block is screwed to the bottom of the spring tube. A pressure adjusting component is provided on one side of the spring tube and installed in the middle of the C-shaped plate.

[0008] Preferably, the support plate has multiple sliding cylinders at both ends, and a sliding rod is slidably installed inside the sliding cylinder. The upper and lower ends of the sliding rod are fixed to one side of the limiting plate. Multiple hydraulic cylinders are fixedly installed in the middle of the control base, and the top actuating end of the hydraulic cylinder is fixedly connected to the bottom of the support plate.

[0009] Preferably, the mounting buckle has a mounting plate welded to its bottom, and the support plate has multiple rows of neatly arranged first screw holes for mounting the mounting plate. The mounting plate has a first threaded tube at its top, and a first threaded rod is connected to the inside of the first threaded tube by a nut. A first knob is welded to the top of the first threaded rod, and a rubber pad is fitted at the bottom of the first threaded rod.

[0010] Preferably, the measuring component includes a protective sleeve mounted between the two limiting plates, with multiple microscopic cameras installed inside the protective sleeve, and a display machine installed at one end of the control base. The multiple microscopic cameras are connected to the display machine via cables.

[0011] Preferably, two straight plates are welded to the upper and lower ends of the C-shaped plate away from the spring tube, and multiple bolt grooves for bolt connection are opened on the surface of the gantry middle plate and the straight plates.

[0012] Preferably, the bottom of the spring tube passes through the C-shaped plate, a cylindrical groove is formed on the inner wall of the bottom end of the spring tube, a cylindrical block is movably provided on the inner wall of the cylindrical groove, a high-precision spring is fixedly connected to the top of the cylindrical block, and a sliding block is slidably provided on the inner wall of the spring tube and fixedly connected to the top of the high-precision spring.

[0013] Preferably, the pressure regulating component includes a second threaded rod rotatably mounted in the middle of the C-shaped plate, a second threaded cylinder connected to the middle of the second threaded rod by a nut, the second threaded cylinder being connected to the sliding block via a connecting rod, a handle welded to the top of the second threaded rod, a scale line drawn on one side of the spring tube, and a pointer welded to the side of the connecting rod near the scale line.

[0014] In summary, this technical solution has the following main advantages:

[0015] This invention allows the device to select indenters with different structures according to testing needs by making the pressure blocks and indenters interchangeable. This enables the observation of the pressure resistance of the alloy material to different structural loads. The pressure on the top of the pressure block during hardness testing can be adjusted by changing the deformation of the high-precision spring, thereby detecting the pressure resistance data of the alloy material to different loads. This method can use different pressure blocks under the same pressure as a control, or use the same pressure block adjusted to different pressures as a control, improving the flexibility and accuracy of the test.

[0016] By adjusting the position of the mounting clips on the support plate, alloy materials of different sizes can be fixed to the surface of the support plate. When multiple hydraulic cylinders are fully extended, they can lift the alloy materials to a suitable position, so that the pressure applied by the high-precision spring is the pressure ballasted on the alloy materials. Multiple microscopic cameras capture the deformation of the alloy materials, and the image signal is transmitted to a monitor via cables. The operator can electronically measure the deformation at this time through the image in the monitor, thereby accurately calculating the hardness of the alloy materials. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example

[0026] Please refer to the attached document carefully. Figure 1 ,2 As shown in Figures 4 and 5, a hardness testing device for alloy special material production includes a control base 10. Two limiting plates 11 are symmetrically fixedly installed on both sides of the top of the control base 10. A gantry frame 19 is mounted on the top of the two limiting plates 11. A support plate 12 is slidably installed on the top of the two limiting plates 11. Multiple mounting buckles 13 are fixedly installed on the support plate 12. A measuring component 14 is fixedly installed in the middle of one side of the two limiting plates 11. Multiple C-shaped plates 15 are fixedly installed on one side of the gantry frame 19. A spring tube 16 is fixedly installed in the middle of the C-shaped plate 15. A pressure block 17 is screwed to the bottom of the spring tube 16. A pressure adjusting component 18 is installed in the middle of the C-shaped plate 15 on one side of the spring tube 16. Two straight plates 151 are welded to the upper and lower ends of the side of the C-shaped plate 15 away from the spring tube 16. The middle plate of the gantry frame 19 and the surface of the straight plates 151 are also included. Multiple bolt slots 152 for bolt connection are provided; the bottom of the spring tube 16 passes through the C-shaped plate 15, and a cylindrical groove 161 is provided on the inner wall of the bottom end of the spring tube 16. A cylindrical block 162 is movably provided on the inner wall of the cylindrical groove 161. A high-precision spring 163 is fixedly connected to the top of the cylindrical block 162. A sliding block 164 is slidably provided on the inner wall of the spring tube 16 and fixedly connected to the top of the high-precision spring 163. The pressure regulating component 18 includes a second threaded rod 181 rotatably installed in the middle of the C-shaped plate 15. A second threaded cylinder 182 is connected to the middle of the second threaded rod 181 by a nut. The second threaded cylinder 182 and the sliding block 164 are connected by a connecting rod 183. A handle 184 is welded to the top of the second threaded rod 181. A scale line 185 is drawn on one side of the spring tube 16. A pointer 186 is welded to the side of the connecting rod 183 near the scale line 185.

[0027] As described above, the cylindrical block 162 has a screw groove at its bottom for connecting the pressure block 17. The pressure block 17 can be screwed to replace various pressure heads with different structures, allowing for targeted use according to testing needs. This enables observation of the pressure resistance performance of the alloy material under different structural loads. In actual use, if it is necessary to test the pressure resistance performance of different structure pressure blocks 17 at once, multiple C-shaped plates 15 can be installed on the gantry 19 through multiple bolt grooves 152 on the surface of the gantry 19 and the straight plate 151. Each different C-shaped plate 15 has a different pressure block 17 with a different pressure head structure screwed onto the cylindrical block 162. This allows the pressure resistance effect of different structures of the alloy material to be read in one pressure resistance test. High precision The spring 163 has a certain deformation that is precisely proportional to the pressure. By rotating the handle 184, the second threaded rod 181 drives the second threaded cylinder 182, the connecting rod 183, and the sliding block 164 to rise and fall, thereby adjusting the deformation of the high-precision spring 163. The pressure of the high-precision spring 163 can be determined by the scale line 185 and the pointer 186. In this way, the pressure on the top of the pressure block 17 during hardness testing can be adjusted, thereby detecting the pressure resistance data of the alloy material to different pressure loads. In this embodiment, different pressure blocks 17 can be used on multiple C-shaped plates 15 with the same pressure as a control, or the same pressure block 17 can be used with different pressures as a control.

[0028] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 3 and 6, the support plate 12 has multiple sliding cylinders 121 at both ends, and sliding rods 122 are slidably installed inside the sliding cylinders 121. The upper and lower ends of the sliding rods 122 are fixed to one side of the limiting plate 11. Multiple hydraulic cylinders 123 are fixedly installed in the middle of the control base 10, and the top execution end of the hydraulic cylinders 123 is fixedly connected to the bottom of the support plate 12. The bottom of the mounting buckle 13 is welded with a mounting plate 131. The surface of the support plate 12 has multiple rows of neatly arranged first screw holes 132 for mounting the mounting plate 131. The top of the mounting plate 131 is provided with... There is a first threaded tube 133, and a first threaded rod 134 is connected to the first threaded tube 133 by a nut. A first knob 135 is welded to the top of the first threaded rod 134, and a rubber pad 136 is fitted to the bottom of the first threaded rod 134. The measuring component 14 includes a protective sleeve 141 mounted in the middle of two limiting plates 11. Multiple microscopic cameras 142 are installed inside the protective sleeve 141. A display 143 is installed at one end of the control base 10. The multiple microscopic cameras 142 and the display 143 are connected by a cable 144.

[0029] The alloy material is placed on top of the support plate 12. The position of the mounting buckle 13 is adjusted according to the size of the alloy material. The mounting buckle 13 is installed through the mounting plate 131 and the first screw hole 132, causing the rubber pad 136 to float above the surface of the alloy material. The first knob 135 is rotated, causing the first threaded rod 134 to rotate and descend inside the first threaded tube 133, pressing the rubber pad 136 onto the surface of the alloy material to complete the fixation. When the multiple hydraulic cylinders 123 are fully extended, they can lift the alloy material to the pressure block 17. The cylindrical block 162 is suspended in the cylindrical groove 161. The supporting force of the high-precision spring 163 and the alloy material balances the cylindrical block 162. At this time, the pressure applied by the high-precision spring 163 is the pressure ballasted on the alloy material. At this time, a small deformation will occur on the surface of the alloy material. Multiple microscopic cameras 142 capture this change and transmit the image signal to the display 143 through the cable 144. The staff can electronically measure the deformation at this time through the image in the display 143, and thus calculate the hardness of the alloy material.

[0030] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
