Description

Technical Field

[0001] The utility model relates to the field of testing equipment, in particular to a metal material torsion testing machine. Background Art

[0002] A metal material torsion testing machine is an experimental device used to test the performance and characteristics of metal materials when subjected to torsion. This testing machine is usually used for material mechanical property testing and research to evaluate parameters such as strength, toughness, and deformation behavior of metal materials under torsion loading. The torsion testing machine applies torsional force or torque to the metal sample to cause torsional deformation, thereby measuring the material's stress-strain relationship, yield strength, torsional strength, plastic deformation and other performance indicators under torsion loading. These data are of great significance for designing engineering structures, formulating metal processing processes, and evaluating material properties. In torsion tests, the change curve of torque over time or torsion angle is usually recorded to analyze the torsional characteristics of the material. The torsion testing machine can be used to evaluate the mechanical properties of metal materials under torsion loading, providing an important reference for engineering design and material selection. This testing equipment has a wide range of applications in material science research, metal processing process optimization and other fields.

[0003] Existing metal material torsion testing machines can usually only effectively clamp and fix metal materials with relatively fixed shape specifications during testing; however, for some special-shaped metal materials, this testing machine may not be able to provide sufficiently stable clamping, resulting in difficulties in torsion testing; in this case, the operator may need to use additional means to ensure that these special-shaped materials can be firmly fixed; this limitation may bring certain challenges and complexities to the testing process, because the special shape and structure of special-shaped metal materials may not be suitable for the design of existing clamping systems; since the clamping capacity of the testing machine is limited by the shape specifications, handling special-shaped materials may require more manpower and time investment to ensure that the stability and accuracy of the materials can be maintained during the test; therefore, for these special-shaped metal materials, operators may need to take additional measures and means to ensure that they can be properly fixed and supported during the torsion test.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3, the utility model provides an embodiment: a metal material torsion testing machine, including a cabinet 1, a vertical frame 3 is fixedly connected to the top of the cabinet 1, a connecting pipe 5 is arranged inside the vertical frame 3, a clamping pipe 6 is fixedly connected to one side of the connecting pipe 5, a motor 8 is arranged inside the clamping pipe 6, a two-way threaded column 9 is fixedly connected to the output end of the motor 8, the two-way threaded column 9 is rotatably connected to the inside of the clamping tube 6, a butt plate 7 is threadedly connected to the outer wall of the two-way threaded column 9, a chuck 10 is rotatably connected inside the butt plate 7, a chuck 10 is rotatably connected inside the chuck 10, a chuck 2 11 is rotatably connected inside the chuck 2 11, a chuck 3 12 is rotatably connected inside the chuck 3 12, a rubber strip 13 is fixedly connected to one side of the chuck 3 12, and a limited position component is arranged inside the vertical frame 3; refer to Figure 4 The limiting assembly includes a fixing frame 4 and a limiting plate 19, wherein the fixing frame 4 is fixedly connected to the bottom of the inner wall of the vertical frame 3, and the limiting plate 19 is fixedly connected to the top of the inner wall of the vertical frame 3;

[0031] Specifically, when clamping metal materials, first pass the material through the connecting tube 5 and move it to the clamping tube 6 position, then start the motor 8 to drive the bidirectional threaded column 9 to start rotating, and as the bidirectional threaded column 9 rotates, the docking plates 7 on both sides will move toward the center position, and this movement process causes the chuck 1 10, chuck 2 11 and chuck 3 12 to start rotating, adapting to and fixing the shape of the material, and at the same time, the rubber strip 13 is close to the material to ensure that it is firmly clamped for subsequent testing; through this operation step, the tested metal material can be reliably clamped and fixed in the clamping structure in the test mechanism 2, and this double-head clamping method ensures the stability and accuracy of the material during the test process, providing a reliable basis for subsequent experiments; the automated design of the entire clamping process makes the operation more efficient and precise, while ensuring the consistency and repeatability of the clamping process, and the structural design of the system makes the clamping process more intelligent and automated, providing convenience and reliability for material testing.

[0032] The connecting tube 5 is rotatably connected to the inside of the fixing frame 4, the clamping tube 6 is rotatably connected to the inside of the limit plate 19, a test mechanism 2 is arranged on the top of the cabinet 1, a fixing frame 15 is fixedly connected to the top of the cabinet 1, a motor 2 16 is arranged inside the fixing frame 15, a rotating column 17 is fixedly connected to the output end of the motor 2 16, the rotating column 17 is rotatably connected to the inside of the vertical frame 3, a gear 2 18 is fixedly connected to the outer wall of the rotating column 17, a gear 14 is fixedly connected to the outer wall of the clamping tube 6, the gear 14 is meshed with the gear 2 18, a plurality of clamping tubes 6 are arranged, and the clamping tube 6 on one side is arranged inside the test mechanism 2;

[0033] Specifically, by manipulating one side of the motor 2 16, the motor 2 drives the rotating column 17 to rotate. This rotational action causes the rotating column 17 to drive the gear 1 14 to rotate in the opposite direction through the gear 2 18. At the same time, on the other side, the motor 2 16 also drives the rotating column 17 and the gear 2 18 to rotate in the same direction. This design enables the same torque to be achieved through the gear 14, and the metal material is tested. When cyclic torsion is required, it is only necessary to simultaneously operate the dual motors 2 16 in a reverse driving mode. In this way, the torque is synchronized through the gear 2 18 and the gear 1 14. At the same time, the tooth mark design allows the driving force to be more finely controlled. The working principle of this system ensures the accuracy and stability of the torque during the test. The collaborative working mechanism of the dual motors 2 16 makes the test process smoother and more reliable, providing reliable technical support for the evaluation of the performance of metal materials. The precise control and synchronous operation of the torsion test make the experimental data more reliable and accurate, providing an important experimental basis for material engineering research.

[0034] Working principle: When it is necessary to clamp the material, the material is passed through the position of the connecting tube 5, so that the metal material reaches the position of the clamping tube 6. At this time, the motor 8 is started, so that the motor 8 drives the two-way threaded column 9 to start rotating. When the two-way threaded column 9 rotates, the docking plates 7 on both sides will move toward the center position, and then the chuck 10, the chuck 2 11 and the chuck 3 12 are continuously rotated to adapt to the shape of the corresponding material, so that the rubber strip 13 is close to the material, so that the material to be tested is clamped and fixed. The corresponding test mechanism 2 also has a corresponding clamping structure, so as to achieve the clamping of the two ends of the material. Then, by driving the motor 2 16 on one side, the motor 2 16 can drive the rotating column 17 to rotate, thereby driving the gear 1 14 to rotate in the opposite direction through the gear 2 18. At this time, the rotating column 17 and the gear 2 18 driven by the motor 2 16 on the other side rotate in the same direction, and then the torque is achieved through the gear 14, and the metal material is tested. When cyclic torsion is required, it is only necessary to drive the dual motors 2 16 in the opposite direction at the same time, and achieve torque synchronization through the gear 2 18 and the gear 1 14, and the corresponding tooth marks make the driving force more finely controlled.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
