Description

Technical Field

[0001] This utility model relates to the field of ceramic products technology, specifically to a ceramic tie rod used for testing the high temperature resistance and tensile strength of materials. Background Technology

[0002] Because the temperature in the high-temperature furnace is maintained at around 1600℃ for a long time, the traditional tie rod is prone to a decrease in strength due to temperature changes. It is easy to break or be damaged during tensile testing, making it unsuitable for use in environments with rapid heating and cooling. In addition, the traditional tie rod is generally a straight rod structure, which can easily cause the material to be installed at an angle to the tie rod, resulting in uneven stress on the material and affecting the test results.

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] Figure 1 This is a three-dimensional structural schematic diagram of the present invention; Figure 2 This is a cross-sectional view of the present invention. Detailed Implementation

[0014] The present invention will be further described below through specific embodiments, so as to make the technical solution of the present invention easier to understand and master, rather than to limit the present invention.

[0015] Example: See Figures 1 to 2 This embodiment provides a ceramic tie rod for testing the high temperature resistance and tensile strength of materials. The tie rod includes a main tie rod 1, a connecting part 2, and two sets of branch tie rods 3. The main tie rod 1 includes a fixed end and a pull-out end. A plurality of assembly through holes 4 are provided on the fixed end. The connecting part 2 is fixedly connected to the pull-out end. The two sets of branch tie rods 3 are parallel to each other and are fixedly installed at both ends of the connecting part 2 along the setting direction of the main tie rod 1, so that a clearance cavity 5 for avoiding the material to be tested is formed between the two sets of branch tie rods 3; The two sets of branch tie rods 3 are connected at the ends away from the connecting part 2 to form a suspension rod 6. A test mounting through hole 7 for installing the test material is provided through the suspension rod 6 corresponding to the avoidance cavity 5.

[0016] Specifically, the main tie rod 1 is assembled onto the tensile testing device through the assembly through hole 4, and the material to be tested is installed in the installation through hole 7. The tensile testing device is used to pull the tie rod to perform a tensile test on the material to be tested. The tie rod is made of ceramic, which can withstand large temperature changes and will not crack under rapid heating and cooling conditions. It has good corrosion resistance, acid and alkali resistance, wear resistance and high temperature resistance. The two sets of branch tie rods 3 are set in a split structure, which makes the force applied to each set of branch tie rods 3 more uniform. This can avoid damage to the tie rod due to deflection deformation during the tensile test, and ensure that the force direction of the material to be tested is always parallel to the traction direction of the tie rod. This avoids tilting tension caused by unreasonable distribution of traction points, and further improves the accuracy and stability of the tensile test.

[0017] Preferably, the branch tie rod 3 is set in a direction parallel to the main tie rod 1, ensuring that the traction direction of the branch tie rod 3 is always parallel to the traction direction of the main tie rod 1. This ensures that the force direction of the material under test during the tensile test is always parallel to the traction direction of the tie rod, avoiding the generation of tilting tension that would affect the accuracy of the tensile test.

[0018] Furthermore, the suspension rod 6 is set in a direction perpendicular to the branch tie rod 3, ensuring that the traction force is applied evenly to the material under test, avoiding tilting force due to unreasonable distribution of traction points, and further improving the accuracy of the traction test.

[0019] Furthermore, the assembly through hole 4 is set in a direction perpendicular to the setting direction of the installation through hole 7 to be tested, so that the assembly and locking direction of the pull rod is perpendicular to the installation direction of the material to be tested, thereby preventing the pull rod and / or the material to be tested from falling off due to excessive traction force during the tensile test.

[0020] Furthermore, the width of the connecting part 2 gradually increases from near to far from the main tie rod 1.

[0021] In this embodiment, the main tie rod 1 is a cylindrical tie rod, and the branch tie rod 3 is a square column tie rod.

[0022] When this utility model is in operation, it includes the following steps: (1) The main tie rod 1 is assembled onto the tensile testing device by means of a pin through the assembly through hole 4; (2) The material to be tested is installed on the test mounting through hole 7; (3) The tensile testing device starts working and applies different tensile forces to the material to be tested in order to complete the tensile test.

[0023] This utility model features a reasonable and ingenious design. The main tie rod is assembled onto the tensile testing device through the assembly through hole, and the material to be tested is installed in the test mounting through hole. By using the tensile testing device to pull the tie rod, a tensile test can be performed on the material to be tested. Furthermore, the tie rod is made of ceramic, which can withstand large temperature differences and will not crack under rapid heating and cooling conditions. It also has excellent corrosion resistance, acid and alkali resistance, wear resistance, and high temperature resistance. The two sets of branch tie rods are arranged in a split structure, which makes the force applied to each set of branch tie rods more even. This avoids damage to the tie rods due to deflection deformation during the tensile test and ensures that the force direction of the material to be tested is always parallel to the traction direction of the tie rod. This avoids tilting tension caused by unreasonable distribution of traction points, further improving the accuracy and stability of the tensile test.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model using the disclosed technical means and content, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. Therefore, all equivalent changes made based on the shape, structure, and principle of this utility model without departing from its technical solution should be covered within the protection scope of this utility model.
