Description

Technical Field

[0001] This utility model relates to the field of new material strength testing technology, specifically a new material strength testing device. Background Technology

[0002] The strength testing device for new materials is used to evaluate the ability of new materials to resist damage by external forces. By applying different types of forces such as tension, compression, bending, and shear to the sample, the stress-strain curve of the material during the stress process is measured, thereby obtaining the mechanical properties of the material such as strength, toughness, and elastic modulus.

[0003] In the comparative case, patent publication number CN222506042U, this utility model relates to the technical field of material strength testing equipment, and discloses a new material strength testing device; it includes a base plate, and further includes: a support column fixed to the top of the base plate, the other end of the support column being fixedly connected to a top plate, and a fixing component being provided on the top of the top plate; a pressure component disposed on one side of the fixing component, the pressure component including a cylinder. This utility model can easily fix the pressure component by setting the fixing component, and by setting the pressure component, it can easily drive the detector to perform bending strength testing on the pipe, while also facilitating the installation and replacement of the detector. By setting the fixing component, it can easily fix pipes of different thicknesses. It is noted here that the fixing component is detachable, and by setting a driving component, it can easily drive the fixing component to move, thereby facilitating the fixing of pipes of different lengths.

[0004] However, in implementing the relevant technology, the strength testing device for the aforementioned new material has the following problems. In the comparative case, the pressure component can be easily fixed by the fixing component. By setting the pressure component, it is convenient to drive the detector to perform bending strength testing on the pipe, and it is also convenient to install and replace the detector. By setting the fixing component, it is convenient to fix pipes of different thicknesses. In the existing new material research and development process, the strength test results can provide key feedback to the researchers. Researchers can analyze the reasons for insufficient material strength based on the test data, such as improper component ratio, defects in the preparation process, etc., so as to adjust the research and development direction in a targeted manner, improve the material formula or preparation process, so as to improve the material strength and optimize the material performance. However, in the impact force test, the new material is prone to deformation, cracking or falling off the operating table of the strength testing equipment, which affects the safety of the operator and reduces the safety of the strength testing equipment.

[0005] Therefore, it is necessary to redesign and modify the strength testing equipment to effectively prevent the strength test results from providing key feedback to R&D personnel during the research and development of new materials. R&D personnel can analyze the reasons for insufficient material strength based on the test data, such as improper component ratios or defects in the preparation process, and thus adjust the R&D direction in a targeted manner, improve the material formula or preparation process to improve material strength and optimize material performance. However, in the impact force test, new materials are prone to deformation, cracking or falling off the equipment's operating table when impacted, which affects the safety of the operator.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, the present invention provides a new material strength testing device, comprising:

[0024] Impact testing machine 1, with a workbench 2 fixedly connected to the top of the impact testing machine 1, a placement platform 3 fixedly connected to the center of the workbench 2, and fixed boxes 4 fixedly connected to the left and right sides of the top of the workbench 2, with a transmission mechanism 5 movably connected to the front and back ends of the left side of the fixed box 4.

[0025] The transmission mechanism 5 includes a connecting rod 51, a rectangular block 52, and an arc plate 53. The front and back ends of the left side of the fixed box 4 are movably connected to the connecting rod 51. The right side of the connecting rod 51 extends through the inside of the fixed box 4 and is fixedly connected to the rectangular block 52. The left side of the connecting rod 51 is fixedly connected to the arc plate 53. The inner side of the rectangular block 52 is fixedly connected to the connecting mechanism 6.

[0026] refer to Figure 4 The connecting mechanism 6 includes a connecting block 61, a semi-circular disk 62, and a sliding column 63. The connecting block 61 is fixedly connected to the inner side of the rectangular block 52, the semi-circular disk 62 is fixedly connected to the inner side of the connecting block 61, the sliding column 63 is slidably connected to the top of the semi-circular disk 62, and the driving mechanism 7 is fixedly connected to the right side of the inner wall of the fixed box 4.

[0027] As a technical optimization of this utility model, by setting the connecting mechanism 6, the sliding column 63 can rotate on the surface of the semi-circular disk 62 and force the semi-circular disk 62 to move. The movement of the semi-circular disk 62 drives the connecting block 61 to follow the movement and complete the power transmission, thereby realizing the control of the movement direction of the semi-circular disk 62 and avoiding the inaccurate movement direction of the semi-circular disk 62 from affecting the stability of the mechanical work.

[0028] refer to Figure 4The drive mechanism 7 includes a support base 71, a servo motor 72, a turntable 73, and a U-shaped sleeve 74. The support base 71 is fixedly connected to the right side of the inner wall of the fixed box 4, the servo motor 72 is fixedly connected to the left side of the support base 71, the turntable 73 is fixedly connected to the output end of the servo motor 72, the U-shaped sleeve 74 is fixedly sleeved on the left side of the turntable 73, the top of the sliding column 63 is fixedly connected to the bottom of the U-shaped sleeve 74, and the top and bottom of the front end of the rectangular block 52 are fixedly connected to limit components 8.

[0029] As a technical optimization of this utility model, the drive mechanism 7 enables the servo motor 72 to drive the turntable 73 to rotate clockwise. The rotation of the turntable 73 causes the U-shaped sleeve 74 to move accordingly, and the movement of the U-shaped sleeve 74 causes the sliding column 63 to move synchronously. This realizes the transmission of the rotation power of the turntable 73 to the sliding column 63, thereby realizing the mechanical power drive and cooperating with the encoder in the servo motor 72 to accurately position the rotation angle and position of the turntable 73 to ensure stable operation.

[0030] refer to Figure 4 The limiting component 8 includes a slider 81 and a horizontal plate 82. The top and bottom of the front end of the rectangular block 52 are fixedly connected to the slider 81. The top and bottom of the right side of the inner wall of the fixed box 4 are fixedly connected to the horizontal plate 82. The left side of the horizontal plate 82 passes through the left side of the slider 81 and is fixedly connected to the left side of the inner wall of the fixed box 4.

[0031] As a technical optimization of this utility model, by setting the limiting component 8, the slider 81 can follow the rectangular block 52 to move, and the slider 81 moves horizontally along the surface of the horizontal plate 82, thereby keeping the mechanical parts stable during the movement.

[0032] refer to Figure 4 A D-shaped groove 9 is provided on the surface of the semi-circular disk 62 at the position corresponding to the sliding column 63. The D-shaped groove 9 is used in conjunction with the sliding column 63.

[0033] As a technical optimization of this utility model, by setting the D-shaped groove 9, the sliding column 63 can move inside the D-shaped groove 9, and at the same time, it plays a limiting role, preventing the sliding column 63 from detaching during the movement.

[0034] refer to Figure 3 A rubber pad 10 is fixedly bonded to the surface of the arc plate 53, and the rubber pad 10 is used in conjunction with the arc plate 53.

[0035] As a technical optimization of this utility model, the rubber pad 10 can assist the arc plate 53 in its work and also play a protective role, avoiding the phenomenon of scratches and wear caused by direct contact between the arc plate 53 and the new material.

[0036] The working principle and usage process of this utility model are as follows: When using the new material, place it in the center of the placement platform 3, then start the servo motor 72. The servo motor 72 drives the turntable 73 and the U-shaped sleeve 74 to rotate clockwise. The rotation of the U-shaped sleeve 74 causes the sliding column 63 to rotate accordingly. The sliding column 63 moves along the D-shaped groove 9 on the surface of the semi-circular disk 62. When the sliding column 63 moves to the left side of the D-shaped groove 9, it forces the semi-circular disk 62 to move to the left. The leftward movement of the semi-circular disk 62 causes the connecting block 61 and the rectangular block 52 to move synchronously. The leftward movement of the rectangular block 52 causes the slider 81 and the connecting block 61 to move synchronously. The connecting rod 51 moves along the same path, while the slider 81 moves stably along the surface of the horizontal plate 82. Finally, the connecting rod 51 moves to the left, causing the arc plates 53 to move closer together. When the two arc plates 53 move closer together and clamp and fix the new material, the impact testing machine 1 is started. The new material is impacted at a certain speed using a drop hammer impact device, causing the new material to fracture under the impact load. The impact toughness and impact resistance of the new material are evaluated by measuring the impact energy or the fracture characteristics of the new material. The test results are sensitive to the microstructure and defects of the material and can be used to evaluate the toughness and resistance to brittle fracture of the material.

[0037] In summary, the strength testing device for this new material, using an impact testing machine 1, a workbench 2, a placement platform 3, a fixed box 4, a transmission mechanism 5, a connecting rod 51, a rectangular block 52, an arc-shaped plate 53, and a connecting mechanism 6, works in conjunction. During operation, the rectangular block 52 moves under the influence of external forces, causing the connecting rod 51 and the arc-shaped plate 53 to move synchronously. The two arc-shaped plates 53 move closer together to clamp and fix the new material at the center of the placement platform 3, ensuring that even if the new material deforms and cracks under impact, it will not scatter debris. At the same time, the arc-shaped plates 53 fix the new material, making it more stable to accept the impact test and improving accuracy. This solves the problem that existing strength testing equipment can provide key feedback to researchers during the development of new materials. Researchers can analyze the reasons for insufficient material strength based on the test data, such as improper component ratios or defects in the preparation process, and thus adjust the research direction in a targeted manner, improve the material formula or preparation process to improve material strength and optimize material performance. In contrast, strength testing equipment often causes new materials to deform, crack, or detach from the equipment's operating platform during impact testing, affecting operator safety.
