Description

Technical Field

[0001] The present application relates to the field of hardness testers, and in particular to a hydraulic Shore hardness tester. Background Art

[0002] A hardness tester is an instrument that measures the hardness of an object, indicating the material's ability to resist a hard object from pressing into its surface. According to the degree of complexity, it can be divided into two types: simple hardness testers and complex hardness testers. Hardness testers are widely used and are commonly used in the rubber industry. In the screen printing process, hardness testers are mainly used to detect the hardness of scraper materials.

[0003] Hardness is one of the important performance indicators of materials. Generally, the higher the hardness, the better the wear resistance. According to the hardness unit measured, the hardness tester can be divided into: Rockwell hardness tester, Vickers hardness tester, microhardness tester, Brinell hardness tester, Shore hardness tester, Barcol hardness tester, Leeb hardness tester, Webster hardness tester, Shore hardness tester, and Burke hardness tester.

[0004] The existing Shore hardness tester uses manual pressure to drive the ejector pin to push against the object to be tested, which is laborious to use. If the number of tests needs to be calculated, the number can only be remembered manually. Its function is only to detect the hardness value, and its function is single. Utility Model Content

[0005] Therefore, it is necessary to provide a hydraulic Shore hardness tester to solve the problems in the prior art that the hardness tester needs to be manually controlled, is laborious and inaccurate to use, and cannot count automatically.

[0014] In some embodiments, the counter is provided with a contact switch and a contact point. The contact switch extends vertically, and the contact point is located on the workbench.

[0016] In some embodiments, the lifting drive mechanism further includes an oil supply assembly, a directional valve group, a hydraulic inlet pipe, and a hydraulic return pipe; the oil inlet of the hydraulic inlet pipe and the oil inlet of the hydraulic outlet pipe are both connected to the oil supply assembly through the directional valve group, the oil outlet of the hydraulic inlet pipe is connected to the oil inlet of the hydraulic cylinder, and the hydraulic return pipe is connected to the oil outlet of the hydraulic cylinder.

[0017] In some embodiments, the lifting drive mechanism further includes a hydraulic controller, and the hydraulic controller is connected to the oil supply assembly and the directional valve group.

Therefore, this application can not only be used for simple hardness value detection, but also for yield value detection, that is, for detecting at which time the object to be detected is extruded and the hardness value will change violently. For example, it can be used for testing how many times a popcorn sole loses its elasticity when stepped on, or for simulating and detecting how many times a ball does not rebound after being kicked. In this application, this number is called the yield value or elastic modulus.

[0057] A hardness tester is an instrument for measuring the hardness of an object, which represents the ability of a material to resist the penetration of a hard object into its surface. According to the complexity, it can be divided into two types: simple hardness measuring instruments and complex hardness measuring instruments. Hardness measuring instruments have a wide range of uses and are commonly used in the rubber industry. During the screen printing process, hardness testers are mainly used to detect the hardness of the squeegee material.

[0058] Hardness is one of the important performance indicators of materials. Generally, the higher the hardness, the better the wear resistance. According to the hardness unit measured, the hardness tester can be divided into: Rockwell hardness tester, Vickers hardness tester, microhardness tester, Brinell hardness tester, Shore hardness tester, Barcol hardness tester, Leeb hardness tester, Webster hardness tester, Shore hardness tester, and Burke hardness tester.

[0059] The existing Shore hardness tester is driven by manual pressing to drive the ejector pin to push against the object to be tested 10, which is laborious to use. If the number of tests needs to be calculated, the number can only be remembered manually. The function is only to test the hardness value, and the function is single.

[0060] To this end, the utility model provides a hydraulic Shore hardness tester, which can detect the hardness value of an object, and can also be used to detect the yield value / elastic modulus of an object, especially can be used to detect the elastic yield value / elastic modulus of silicone and coatings. The hardness tester body 1 can automatically rise and fall repeatedly, and can automatically calculate the number of times the hardness tester body 1 falls, thereby efficiently and labor-savingly providing a data basis for obtaining the yield value / elastic modulus, and has more functions.

[0061] See also Figure 1 and Figure 2 In a specific embodiment, the hydraulic Shore hardness tester includes a hardness tester body 1, a lifting drive mechanism, a counter 3, and a workbench 4; the lifting drive mechanism includes a hydraulic cylinder 2, the output end of the hydraulic cylinder 2 is connected to the hardness tester body 1, and is used to drive the hardness tester body 1 to rise and fall; the counter 3 is arranged at the hardness tester body, and is used to record the number of times the hardness tester body 1 falls; the workbench 4 is located under the hardness tester body 1, and is used to support the object to be tested 10.

[0062] Since the hydraulic Shore hardness tester is provided with a lifting drive mechanism and the lifting mechanism includes a hydraulic cylinder 2, it can be realized by hydraulic autonomous mechanical repeated lifting, and the hydraulic cylinder 2 drives the hardness tester body 1 to detect the hardness value, and the downward pressure is precisely controlled, without manual operation, saving time and effort, and high efficiency; since the hydraulic Shore hardness tester is provided with a counter 3, it can autonomously calculate the number of times the hardness tester body 1 descends to perform hardness detection, without manual squatting and calculation, and high efficiency, so the present application can not only be used for simple hardness value detection, but also for yield value detection, that is, for detecting the hardness value of the object to be detected 10 will change drastically when it is squeezed for the first time, such as being used to test the number of times the sole of a popcorn shoe is stepped on without elasticity, such as being used to simulate the number of times a ball does not rebound after being kicked out, in the present application, this number is called yield value or elastic modulus. The present application can be pressed automatically without manual pressing, and has an automatic counting function, so it is convenient for users to observe the number of times the hardness value converges and changes, and it is convenient and efficient to use, and can detect hardness values ​​and yield values, and has more powerful functions.

[0063] In some embodiments, the hardness tester body 1 includes a hardness indenter, which is vertically provided at the bottom end of the hardness tester body and is a component that directly contacts the object to be detected.

[0064] In some embodiments, the hardness tester body 1 is provided with a hardness display 100 for displaying the hardness value detected by the hardness tester body 1, facilitating the user to obtain the hardness value detected by the hardness tester body 1.

[0065] In some embodiments, a memory is further included, which is connected to the hardness tester body 1 and is used for storing the hardness value detected by the hardness tester body 1.

[0066] In some embodiments, the counter 3 is provided with a contact switch 300 and a contact point 301. The contact switch 300 extends vertically, and the contact point 301 is located on the workbench 4. Please refer to Figure 3 When the hardness tester body 1 does not descend, there is a distance between the contact switch 300 and the contact point 301. Please refer to Figure 4 When the hardness tester body 1 descends to abut against the object to be detected 10, the contact switch 300 abuts against the contact point 301 and is triggered.

[0067] In some embodiments, the counter 3 is further provided with a times display 302, which is used for displaying the number of times the hardness tester body 1 descends, facilitating the user to obtain the number of times the hardness tester body 1 descends.

[0068] In some embodiments, the lifting drive mechanism further includes an oil supply assembly, a directional valve group 13, a hydraulic inlet pipe 5, and a hydraulic return pipe 6. The oil inlet of the hydraulic inlet pipe 5 and the oil inlet of the hydraulic outlet pipe are both connected to the oil supply assembly through the directional valve group 13. The oil outlet of the hydraulic inlet pipe 5 is connected to the oil inlet of the hydraulic cylinder 2, and the hydraulic return pipe 6 is connected to the oil outlet of the hydraulic cylinder 2. The oil supply assembly can supply oil to the hydraulic cylinder 2, and the directional valve group 13 can change the path of the oil supply assembly to supply oil to the hydraulic cylinder 2.

[0069] In some embodiments, the lifting drive mechanism further includes a hydraulic controller 7, which is connected to the oil supply assembly and the directional valve group 13. The oil supply assembly includes an oil tank and a hydraulic pump 12. The hydraulic controller is used to control the oil supply assembly and the directional valve group 13 to achieve controlling whether the output end of the hydraulic cylinder 2 retracts or extends.

[0070] Taking the object to be detected 10 as a coating film as an example, when the coating film is repeatedly pressed and breaks through the yield value, we will observe a suddenly rising value (the coating film suddenly becomes very hard, not a slow change process, equivalent to being damaged).

[0071] To ensure that the hardness tester body 1 counts only after a stable value is obtained when it presses down, so that the calculated number of times are all valid times. In some embodiments, the lifting drive mechanism further includes a timing mechanism and a main controller 11, and the main controller 11 is connected to the timing mechanism and the hydraulic controller 7. The timing mechanism can be used to calculate the total duration of the hardness tester body 1 descending and staying at the position to be detected, or to calculate the duration of the hardness tester body 1 staying at the object to be detected 10. When the main controller 11 receives the detection duration from the timing mechanism and determines that the total duration of the hardness tester body 1 descending and staying at the position to be detected (or the duration of the hardness tester body 1 staying at the object to be detected 10) meets the requirements, it then allows the hydraulic controller 7 to control the output end of the hydraulic cylinder 2 to retract. In this way, it can be ensured that the value detected by the hardness tester body 1 during this count by the counter 3 is stable.

[0072] In one embodiment, the timing mechanism is used to calculate the duration of the hardness tester body 1 staying at the position to be detected. Since the contact 301 switch of the counter 3 is triggered at the first moment when the hardness tester body 1 presses down, therefore, it can be set that after Ns when the contact 301 switch of the counter 3 is triggered, that is, after the hardness tester body 1 stays for Ns, the counter 3 counts a value. For example, the trigger time (staying time) can be set to 5s. In this way, it is beneficial for the hardness tester body 1 to detect a stable value.

[0073] In some embodiments, the timing mechanism may include an electric energy meter 9.

[0074] In one embodiment, the timing mechanism is used to calculate the duration of the hardness tester body 1 staying at the position to be detected. Please refer to Figure 5 , the electric energy meter 9 is connected to the counter 3. For example, when the electric meter runs for NS (such as 5s) and the power flow jumps once, if the electricity consumption in 5s just makes one degree of electricity, that is, the power flow of the counter 3 jumps once, the counter 3 has worked for 5s, and the calculated duration of the hardness tester body 1 staying at the position to be detected is 5s. The main controller 11 receives the signal of the electric energy meter 9 in real time. When the received electricity signal is one degree of electricity, it controls the hydraulic controller 7, so that the hydraulic controller 7 controls the hydraulic pump 12 and the reversing valve group 13 to work, so that the hydraulic cylinder 2 drives the hardness tester body 1 to rise, completing a hardness test, and at the same time the counter 3 completes a count.

[0075] In some embodiments, the timing mechanism further includes a time display 8, and the time display 8 is connected to the main controller 11 and is used to display the total duration of the hardness tester body 1 descending and staying at the position to be detected, or the duration of the hardness tester body 1 staying at the object to be detected 10. After the main controller 11 receives the signal of the electric energy meter 9, it converts it into a time signal and transmits it to the time display 8 for display on the time display 8.
