Description

Technical Field

[0001] The utility model relates to the technical field of metal stress tests, and particularly relates to a metal stress corrosion test device for efficiently simulating a lava environment. Background Technique

[0002] With the continuous development of earth science, geological engineering and deep space exploration technologies, the performance requirements for metal materials in extreme environments are increasing day by day. As one of the most severe environments in nature, the lava environment can reach a temperature of up to thousands of degrees Celsius, accompanied by strong acid-base corrosion and oxidation, which poses a great test to the stress corrosion performance of metal materials.

[0003] Therefore, a test device is needed to conduct simulation tests on applied materials. During the test process of the existing metal stress corrosion test device for simulating a lava environment, samples are usually continuously tested. Therefore, when a sample test is completed, a new sample to be tested needs to be placed into the heating box. Due to the simulation of a high-temperature environment, the temperature inside the heating box is extremely high. When the heating box is opened, the local temperature rises suddenly. When disassembling and removing the completed test sample, heat-insulating clothing needs to be worn. At the same time, opening the lid of the heating box will cause the internal temperature to decrease, and it is necessary to continue heating to the test required temperature during the test, resulting in low test efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a metal stress corrosion test device for efficiently simulating a lava environment, which can quickly replace the samples to be tested, with less temperature loss and high efficiency.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme: a metal stress corrosion test device for efficiently simulating a lava environment, including a simulation box. A vertically rotating material column is arranged inside the simulation box. A plurality of stretching components are arranged in an array along the circumferential side of the material column. The stretching component includes a material groove opened on the material column and two hydraulic cylinders arranged oppositely up and down in the material groove. Clamps are arranged at the piston ends of the two hydraulic cylinders. An opening is arranged on the side wall of the simulation box, and a part of the material column extends out of the simulation box through the opening. A heat-insulating cover is arranged at the opening, and a material taking port corresponding to the material groove is opened on the heat-insulating cover.

[0006] As a further optimization of the metal stress corrosion test device for efficiently simulating a lava environment of the utility model, the material column is rotationally connected to the top wall and the bottom wall of the simulation box through a rotating rod.

[0007] As a further optimization of the metal stress corrosion test device for efficiently simulating a lava environment of the utility model, the rotating rod at the upper end of the material column passes out of the simulation box and is connected to the output shaft of the motor.

[0008] As a further optimization of a metal stress corrosion test device for efficiently simulating a lava environment in the present utility model, a rotating rod at the upper end of the material column passes out of the simulation box and is connected to a driving rod.

[0009] As a further optimization of a metal stress corrosion test device for efficiently simulating a lava environment in the present utility model, the simulation box and the heat insulation cover are integrally formed. The shells of the simulation box and the heat insulation cover are both hollow structures, and the hollow cavity rooms are filled with heat insulation materials.

[0010] As a further optimization of a metal stress corrosion test device for efficiently simulating a lava environment in the present utility model, the two hydraulic cylinders in the material tank are respectively arranged on the top wall and the bottom wall of the material tank.

[0011] As a further optimization of a metal stress corrosion test device for efficiently simulating a lava environment in the present utility model, the outer walls of the simulation box and the heat insulation cover are both wrapped with hollow heat insulation interlayers.

[0012] As a further optimization of a metal stress corrosion test device for efficiently simulating a lava environment in the present utility model, a heat insulation support is provided at the bottom of the simulation box.

[0013] The present utility model has the following beneficial effects: In the present utility model, a material column is vertically rotatably arranged inside the simulation box, and a plurality of stretching components capable of stress stretching the specimen are arranged on the peripheral side of the material column. Since a part of the peripheral side of the material column can be located outside the simulation box, only by controlling the rotation of the material column, the stretching components that need to install or disassemble the specimen can be located outside the simulation box, which is convenient for the installation and disassembly of the specimen. At the same time, the material column always keeps in close contact with the simulation box, which can avoid a large amount of heat loss, thereby improving the test efficiency.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0018] Such as Figure 1-2As shown in the figure, the present utility model provides a metal stress corrosion test device for efficiently simulating a lava environment. When installing a new specimen to be tested during the test process, it is not necessary to open the box door, and the installation can be carried out conveniently and with high efficiency.

[0019] What the test device provided by the present utility model has in common with the prior art is: it includes a simulation box 2 capable of simulating a lava environment. Inside the simulation box 2, there is a heater 9 and an injection port capable of injecting different gases. The heater 9 is used to heat the inside of the simulation box 2, and the injection port can inject the gas required to simulate the environment. The injection port is in a sealed state under normal conditions. The above are all prior arts and will not be elaborated here.

[0020] What the test device in the present utility model is different from the prior art is: inside the simulation box 2, there is a vertical material column 5. The upper and lower end faces of the material column 5 are respectively provided with rotating rods 10 rotatably connected to the top wall and the bottom wall of the simulation box 2. The rotating rods 10 can make the material column 5 rotate vertically inside the simulation box 2. The simulation box 2 is provided with a plurality of stretching components arrayed along its circumferential side. After the simulation box 2 simulates the lava environment, the stretching components stretch the specimen, and thus the test starts.

[0021] In this embodiment, the stretching component includes a material groove 6 opened on the circumferential side of the material column 5 and two hydraulic cylinders 7 arranged oppositely inside the material groove 6. Clamps 8 are provided at the piston ends of the two hydraulic cylinders 7, and the clamps 8 can be selected according to the shape of the specific specimen. By respectively arranging the two ends of the specimen on the two clamps 8 in the material groove 6, the piston ends of the hydraulic cylinders 7 will contract, thereby being able to stretch the specimen.

[0022] In this embodiment, an opening is provided on the side wall of the simulation box 2. A part of the column body of the material column 5 passes through the opening in a fitting manner and is located outside the simulation box 2. When the material column 5 rotates, all the material grooves 6 of the material column 5 can rotate outside the simulation box 2. By only controlling the rotation of the material column 5, the material groove 6 that needs to install or disassemble the specimen can be oriented towards the outside, which is convenient for the installation and disassembly of the specimen and can avoid a large amount of heat loss at the same time. It should be noted here that the opening on the side wall of the simulation box 2 fits tightly with the column body of the material column 5 and slides, and a heat-insulating sealing gasket is embedded on the inner side wall of the opening.

[0023] In order to prevent the part of the column body of the material column 5 located outside the simulation box 2 from consuming the heat inside the simulation box 2, a heat-insulating cover 3 covering the material column 5 is provided on the outer wall of the simulation box 2. A material taking port 4 corresponding to the material groove 6 is opened on the heat-insulating cover 3. The setting of the material taking port 4 is to facilitate the installation and disassembly of the specimen in the material groove 6. At the same time, when disassembling, as long as the specimen to be disassembled is moved to the material taking port 4, it can be waited until the temperature drops before disassembling to avoid the risk of high-temperature scalding.

[0024] In the present utility model, in order to control the rotation of the material column 5, two structures capable of driving its rotation are provided. One structure is electric control. A motor 1 is provided on the upper end face of the simulation box 2. The rotating rod 10 at the upper end of the material column 5 passes through the outside of the simulation box 2 and is connected to the output shaft of the motor 1. Another way is manual control of rotation. The rotating rod 10 at the upper end of the material column 5 passes through the outside of the simulation box 2 and is connected with a driving rod 10. By controlling the rotation of the rotating rod 10 by the staff, the material column 5 is driven to rotate.

[0025] In the present utility model, the simulation box 2 and the heat insulation cover 3 are integrally formed. At the same time, in order to improve the heat preservation effect and avoid heat waste, the shells of the simulation box 2 and the heat insulation cover 3 are provided with a hollow structure, and a heat insulation material is filled in the cavity thereof.

[0026] In the present utility model, both the outer walls of the simulation box 2 and the heat insulation cover 3 are wrapped with a hollow heat insulation layer. The simulation box 2 is further insulated through the hollow heat insulation layer. At the same time, a heat insulation bracket 8 is also provided at the bottom of the simulation box 2.

[0027] The specific embodiments of the present utility model have been described above. It should be understood that the present utility model is not limited to the above specific embodiments, and those skilled in the art can make various deformations or modifications within the scope of the claims, which does not affect the essence of the present utility model.
