Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical material testing, and in particular to a pressure device for chemical material testing. Background Technology
[0002] Tablet presses are mainly used in pharmaceutical industry tablet manufacturing processes. They are automated, continuous production equipment that compresses granular materials into round, irregularly shaped, or tablet-like products with text, symbols, or graphics, with a diameter not exceeding 13mm. After the chemical materials are manufactured, their performance needs to be tested to verify if they meet requirements. One such test is a pressure test, where the chemical materials are loaded into tooling and pressure is applied through a pressure device.
[0003] For example, a patent entitled "A Pressure Device for Testing Chemical Materials" (patent application number: CN202122762052.0) discloses a pressure device for testing chemical materials. The device achieves point contact between the ball and the top of the tooling, thereby applying a vertically downward force to the tooling, which is beneficial for the test. A handwheel is installed on the top of the threaded rod, which facilitates the movement of the threaded rod up and down on the top plate by rotating the handwheel, thus improving the efficiency of the work. However, in addition to point pressure testing, the material also needs to undergo surface pressure testing. A single testing method does not yield sufficiently rigorous data, and if multiple devices are used for different experiments, the cost is high.
[0004] Therefore, it is necessary to propose a pressure device for testing chemical materials to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a pressure device for testing chemical materials, so as to solve the problems that materials need to be subjected to both point pressure testing and surface pressure testing. The data obtained by a single testing method is not rigorous enough, and the cost is high if multiple devices are used to conduct different experiments.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure device for testing chemical materials, comprising:
[0007] Testing station;
[0008] Support frame, the support frame being fixed to the top of the testing table;
[0009] The support frame is provided with a pressure ball at its bottom end, and a pressure cylinder is installed on the outside of the pressure ball.
[0010] A support cylinder is provided, which is located directly below the pressure cylinder and extends into the interior of the support cylinder.
[0011] The support cylinder is equipped with a lifting plate that allows for vertical movement.
[0012] Preferably, both the pressure ball and the lower pressure cylinder have corresponding insertion holes on their outer sides, and a plug is inserted between the two insertion holes for fixation.
[0013] Preferably, a magnetic ring is embedded in the bottom end of the lower cylinder, and an electromagnet corresponding to the position of the magnetic ring is embedded in the top end of the lifting plate.
[0014] Preferably, an electric push rod is fixed inside the testing platform, the top end of the electric push rod extends into the support cylinder, and the extended end is connected to the bottom of the lifting plate.
[0015] Preferably, a pressure sensor is fixed inside the lifting plate.
[0016] Preferably, a pressure gauge is fixed to one side of the top of the testing platform.
[0017] Preferably, a hydraulic cylinder is fixedly connected to the top of the support frame, and a telescopic end is provided at the bottom of the hydraulic cylinder. The telescopic end extends out of the support frame, and the pressure ball is fixed to the bottom of the extended end.
[0018] Preferably, a baffle is fixed to the top of the outer side of the pressure cylinder.
[0019] The technical effects and advantages of this utility model are as follows:
[0020] 1. In the actual operation of this utility model, the chemical material that needs to be pressure tested can be placed inside the support cylinder. By starting the hydraulic cylinder, the pressure ball and the lower cylinder fixed together are driven to descend. As the lower cylinder presses down, the material inside the support cylinder can be squeezed. Since the bottom of the lower cylinder is flat, the material can be in surface contact, and the vertical compression test can be completed.
[0021] 2. Furthermore, after removing the insert, the pressure ball and the lower pressure cylinder can be disconnected. At this time, the lower pressure cylinder is placed inside the support cylinder. By activating the electromagnet, the electromagnet generates magnetic force and attracts the magnetic ring at the bottom of the lower pressure cylinder, thus fixing the lower pressure cylinder. The material to be tested can then be placed inside the lower pressure cylinder. When the pressure ball descends with the hydraulic cylinder, point contact can be achieved, completing the pressure test of the material point.
[0022] 3. The lifting plate can be pushed out of the support cylinder by the electric push rod. After the material has completed the pressure test, the material or the pressure cylinder can be pushed out to avoid getting stuck inside the support cylinder and speed up the time for subsequent personnel to remove the material.

[0028] This utility model provides, for example Figures 1-4 The pressure device for testing chemical materials shown includes: a test platform 1, which is made of high-strength aluminum alloy with an anti-slip surface and four rubber anti-vibration pads installed at the bottom to ensure the stability of the device during operation.
[0029] Support frame 3 is fixed to the top of the testing table 1;
[0030] Among them, the bottom end of the support frame 3 is provided with a pressure ball 8, and a pressure cylinder 5 is installed on the outside of the pressure ball 8;
[0031] Support cylinder 6 is located directly below pressure cylinder 5, and pressure cylinder 5 extends into support cylinder 6. Hydraulic cylinder 4 is fixedly connected to the top of support frame 3. The bottom of hydraulic cylinder 4 is provided with telescopic end, which extends out of support frame 3. Pressure ball 8 is fixed to the bottom of the extended end. Position-corresponding insertion holes 7 are opened on the outer side of pressure ball 8 and pressure cylinder 5. Insertion post 9 is inserted between the two insertion holes 7 for fixation.
[0032] In the actual operation of this utility model, the chemical material that needs to be pressure tested can be placed inside the support cylinder 6. By starting the hydraulic cylinder 4, the pressure ball 8 and the lower cylinder 5 fixed together are driven to descend. As the lower cylinder 5 presses down, it can squeeze the material inside the support cylinder 6. Since the bottom of the lower cylinder 5 is flat, it can make surface contact with the material and complete the vertical compression test.
[0033] The support cylinder 6 is equipped with a lifting plate 11 for lifting.
[0034] A magnetic ring 10 is embedded in the bottom end of the pressure cylinder 5, and an electromagnet 14 corresponding to the position of the magnetic ring 10 is embedded in the top end of the lifting plate 11.
[0035] Furthermore, after removing the insert 9, the pressure ball 8 and the lower pressure cylinder 5 can be disconnected. At this time, the lower pressure cylinder 5 is placed inside the support cylinder 6. By activating the electromagnet 14, the electromagnet 14 generates magnetic force and attracts the magnetic ring 10 at the bottom of the lower pressure cylinder 5, thus fixing the lower pressure cylinder 5. At this time, the material to be tested can be placed inside the lower pressure cylinder 5. When the pressure ball 8 descends with the hydraulic cylinder 4, point contact can be achieved, and the pressure test of the material point can be completed.
[0036] An electric push rod 13 is fixed inside the testing table 1. The top end of the electric push rod 13 extends into the support cylinder 6 and is connected to the bottom of the lifting plate 11. The lifting plate 11 can be pushed out of the support cylinder 6 by the electric push rod 13. After the material has completed the pressure test, the material or the pressure cylinder 5 can be pushed out to avoid getting stuck inside the support cylinder 6.
[0037] A pressure sensor 12 is fixed inside the lifting plate 11, and a pressure gauge 2 is fixed on one side of the top of the detection platform 1. The pressure gauge 2 is connected to the pressure sensor 12 inside the support cylinder 6 to facilitate the detection of pressure data.
[0038] A baffle is fixed to the top of the outer side of the pressure cylinder 5. When the pressure cylinder 5 and the support cylinder 6 are connected, the baffle can block the top of the support cylinder 6 to prevent the material from overflowing from the gap between the pressure cylinder 5 and the support cylinder 6 during pressure testing.
