Description

Technical Field

[0001] This utility model relates to the field of metal hardness testing technology, specifically a hardness testing device for the research and development of metal products. Background Technology

[0002] Hardness is a performance indicator that measures the softness or hardness of metallic materials. Hardness testing is widely used in production practice and scientific research because it is simple, fast, does not damage parts, and has a certain relationship with other mechanical properties. It is used to test and evaluate the performance of metallic materials. There are many hardness testing methods, which can be basically divided into indentation method, scratch method, rebound method, etc.

[0003] In response, Chinese patent application number CN 217425258 U discloses a metal hardness testing device for metal product research and development. The device includes a mounting frame, a testing platform fixedly mounted on the inner bottom wall of the mounting frame, and a pressure head fixedly mounted on the inner top wall of the mounting frame above the testing platform. Cover plates are hinged to both the front and rear sides of the testing platform. Two side guard plates are provided inside the mounting frame, located on the left and right sides of the cover plates. Connection holes are provided on both the left and right sides of the mounting frame. This metal hardness testing device for metal product research and development has advantages such as auxiliary restraint and high protection. It solves the problem that current methods for hardness testing of metal materials used in metal products involve placing the metal to be tested on the testing platform using a clamping mechanism, followed by pressure testing by the pressure head. However, this method only allows clamping regular metal objects, resulting in significant limitations and a lack of protective measures at the testing point, posing a significant safety hazard.

[0004] However, due to its inherent limitations, this structure can only perform simple single-point continuous indentation hardness testing of metal products during the research and development process. The testing area on the metal surface is small, making it impossible to quickly switch and adjust the testing points. This results in certain limitations. Furthermore, the equipment cannot perform more efficient and stable metal loading and unloading, nor can it perform more stable hardness testing, thus failing to meet daily usage requirements. Therefore, there is an urgent need to design a hardness testing device for metal product research and development to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a hardness testing device for metal product research and development, in order to solve the problems mentioned in the background art. In the process of hardness testing of metal products, the existing structure can only perform simple single-point continuous pressing operation hardness testing due to its own limitations. The area of ​​the detection position on the metal surface is small, and it is not possible to quickly switch and adjust the detection point. The detection results have certain limitations. At the same time, the equipment cannot perform more efficient and stable metal loading and unloading, or more stable hardness testing, and cannot meet the needs of daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hardness testing device for metal product research and development, comprising a testing frame, wherein limit grooves are provided on the four sides of the side of the testing frame, lifting push rods are provided at the four corners of the inner wall of the testing frame, a lifting top cover is movably connected to the top of the testing frame, a top push rod is provided on the top of the lifting top cover, and a bottom push rod is provided at the bottom of the testing frame.

[0007] A shrink frame is fixedly connected to the four sides of the detection frame, and a flow guide is provided at the four corners of the shrink frame.

[0008] Preferably, an air pump is provided on one side of the shrink frame, and a dustproof net frame is provided at one end of the air pump.

[0009] Preferably, a guide pipe is fixedly connected to the center of the side of the shrink rack, and a control valve seat is provided at the center of the side of the guide pipe.

[0010] Preferably, the retractable frame is provided with a telescopic airbag inside, and one end of the telescopic airbag is fixedly connected to a top pressure plate frame.

[0011] Preferably, one end of the push rod is fixedly connected to a top pressure seat, and one end of the bottom push rod is fixedly connected to a bottom pressure seat.

[0012] Preferably, the bottom end of the top pressure seat is provided with a top pressure ball, and the surface of the bottom pressure seat is provided with a mating sleeve groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This hardness testing device for metal product research and development, through its testing frame, limiting groove, push rod, shrink frame, guide frame, air pump, dustproof mesh frame, guide pipe, air control valve seat, telescopic airbag, top pressure plate frame, top pressure seat, and top pressure roller, allows for more comprehensive hardness testing of metal products. In actual use, the operator first places the metal product to be tested into the center of the testing frame, then starts the air pump at one end of the shrink frame to draw air from the dustproof mesh frame. The airflow is then controlled and regulated through the four corner guide frames on the side of the shrink frame, the guide pipe on the side of the shrink frame, and the air control valve seat. The system operates by controlling the extension and retraction of the telescopic airbags inside the shrink frame. The top pressure plate at one end of the telescopic airbag passes through the limiting groove of the testing frame and abuts against the four sides of the metal product, quickly and securely fixing it in place. Then, the push rod is activated, pressing the top pressure roller at one end against the top of the metal product. The shrink frame on the side of the testing frame is then controlled to adjust the extension and retraction of the four sets of telescopic airbags and the top pressure plate, adjusting the position of the metal product. The top pressure roller at the bottom of the top pressure seat quickly adjusts its position on the surface of the metal product, enabling a more comprehensive all-around hardness test and demonstrating the practicality of the equipment design.

[0015] This hardness testing device for metal products, through its testing frame, lifting push rod, lifting top cover, top push rod, bottom push rod, top pressure seat, bottom pressure seat, top pressure roller, and docking slot, further improves the overall usability of the equipment. During daily use, operators can simultaneously activate the top and bottom push rods at the top and bottom positions. The top and bottom pressure seats at one end of each rod can be fitted together at the top and bottom ends of the metal product. The docking slot on the bottom pressure seat surface can also be fitted together with the top pressure roller at the bottom of the top pressure seat. When the top pressure roller causes deformation of the metal product, the docking slot of the bottom pressure seat provides stable fitting and bearing protection, preventing the metal product from breaking. Simultaneously, the lifting push rods at the four corners of the inner wall of the testing frame can be activated to quickly adjust the lifting top cover at the top of the testing frame, enabling rapid loading and unloading of metal products within the testing frame, demonstrating the comprehensiveness of the equipment design.

[0022] Please see Figure 1-4 One embodiment provided by this utility model:

[0023] A hardness testing device for metal product research and development includes a testing frame 1. Limiting grooves 2 are formed on the four sides of the testing frame 1. Lifting push rods 3 are provided at the four corners of the inner wall of the testing frame 1. A lifting top cover 4 is movably connected to the top of the testing frame 1. A top push rod 5 is provided on the top of the lifting top cover 4. A bottom push rod 6 is provided at the bottom of the testing frame 1. One end of the top push rod 5 is fixedly connected to a top pressure seat 15, and one end of the bottom push rod 6 is fixedly connected to a bottom pressure seat 16. A top pressure ball 17 is provided at the bottom of the top pressure seat 15. A mating groove 18 is formed on the surface of the bottom pressure seat 16. The top push rod 5 and bottom push rod 6 are simultaneously activated at their upper and lower positions. The top pressure seat 15 and bottom pressure seat 16 at one end of each of the top push rod 5 and bottom push rod 6 can be mated together at the upper and lower ends of the metal product. The mating groove 18 on the surface of the bottom pressure seat 16 can also be mated together with the top pressure ball 17 at the bottom of the top pressure seat 15.

[0024] A shrink frame 7 is fixedly connected to the four sides of the inspection frame 1. A flow guide frame 8 is set at the four corners of the shrink frame 7. An air pump 9 is set on one side of the shrink frame 7. A dustproof net frame 10 is set at one end of the air pump 9. A flow guide pipe 11 is fixedly connected to the center of the side of the shrink frame 7. An air control valve seat 12 is set at the center of the side of the flow guide pipe 11. A telescopic airbag 13 is set inside the shrink frame 7. A top pressure plate frame 14 is fixedly connected to one end of the telescopic airbag 13. When the air pump 9 at one end of the shrink frame 7 is started, air is drawn from the dustproof net frame 10 at one end. The airflow is uniformly flowed and controlled through the flow guide frame 8 at the four corners of the side of the shrink frame 7, as well as the flow guide pipe 11 and air control valve seat 12 on the side of the shrink frame 7. This realizes the telescopic control operation of the telescopic airbag 13 inside the shrink frame 7. The top pressure plate frame 14 at one end of the telescopic airbag 13 passes through the limiting groove 2 of the inspection frame 1 and is pressed against the four sides of the metal product.

[0025] Working Principle: During use, the user first places the metal product to be tested into the center of the testing frame 1. Then, the air pump 9 at one end of the shrink frame 7 is activated, drawing air from the dustproof mesh frame 10 at one end. Airflow is controlled and regulated through the four corner guide frames 8 on the side of the shrink frame 7, the guide pipes 11 on the side of the shrink frame 7, and the air control valve seat 12. This controls the extension and retraction of the internal telescopic airbags 13 of the shrink frame 7. The top pressure plate frame 14 at one end of the telescopic airbag 13 passes through the limiting groove 2 of the testing frame 1 and abuts against the four sides of the metal product, achieving rapid and secure fixation. Then, the push rod 5 is activated, pressing the top pressure ball 17 at one end against the top of the metal product. The shrink frame 7 on the side of the testing frame 1 is then controlled to adjust the extension and retraction of the four sets of telescopic airbags 13 and the top pressure plate frame 14, adjusting the position of the metal product. The bottom top pressure ball 17 of the top pressure seat 15 presses against the metal product. The device allows for rapid surface adjustment and more comprehensive hardness testing of metal products. During daily use, operators can simultaneously activate the top push rod 5 and bottom push rod 6 at the upper and lower positions of the device. The top pressure seat 15 and bottom pressure seat 16 at one end of each of the top push rod 5 and bottom push rod 6 can be fitted together at the upper and lower ends of the metal product. The mating groove 18 on the surface of the bottom pressure seat 16 can also be fitted together with the top pressure roller 17 at the bottom of the top pressure seat 15. When the top pressure roller 17 causes deformation of the metal product, the mating groove 18 of the bottom pressure seat 16 provides stable mating and bearing protection to prevent the metal product from breaking. At the same time, the lifting push rods 3 at the four corners of the inner wall of the testing frame 1 can be activated to quickly adjust the lifting top cover 4 at the top of the testing frame 1, thereby realizing the rapid loading and unloading of metal products inside the testing frame 1. The above is the complete working principle of this utility model.
