[0002] An impact testing method. A heavy hammer is dropped from different heights onto a specimen (sheet, film, product), and the relationship between the drop height and the specimen failure rate is determined. The drop height at which the failure rate is 50% is used to represent the impact resistance of the specimen. A special impact test is used to determine the non-plastic transition (NDT) temperature of steel. Existing technologies for processing notches in drop-weighted specimens in various laboratories mainly involve: specimens are usually grouped one or several (thin specimens) and erected on the support platform of a press base; a line is pre-marked at the opening of the specimen; the blade of the pressing tool coincides with the marked line to achieve the notch pressing process.

[0003] During the experiment, the samples need to be erected one or a group on the support platform of the testing machine. These samples are very prone to tipping over, which poses a certain safety hazard. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] Reference Figure 1-4 An anti-tipping device for notching a sample includes a fixing plate 1, a fixing component 3 is installed at one end of the top outer wall of the fixing plate 1, and a fixing component 5 is provided at the center of the other end of the fixing plate 1. Stabilizing components 4 are provided at both ends of the top outer wall of the fixing plate 1.

[0024] The fixing component 3 includes a limiting plate 7 installed at the center of one end of the fixing plate 1, a threaded hole 8 opened at the center of the other end of the limiting plate 7, and a threaded rod 9 threadedly connected to the inner wall of the threaded hole 8. The threaded rod 9 on the limiting plate 7 drives the pressing plate 10 to move up and down under the rotation of the lever 23, and fixes it in the fixing plate 1 from the top of the sample plate 6 for easy fixing.

[0025] A pressing plate 10 is installed on the bottom outer wall of the threaded rod 9, and mounting holes 2 are opened at the four corners of the top outer wall of the fixing plate 1. The lever 23 drives the threaded rod 9 to rotate, causing the pressing plate 10 to descend and fix the sample plate 6 in the fixing plate 1. Fixing the sample plate 6 facilitates the four opposite directions to fix and support the sample plate 6, prevent the sample plate 6 from tipping over, maintain the safety of the experimental process, and facilitate the combined fixing of the sample.

[0026] Fixing component 25 includes a clamping groove 16 opened at the center of one end of the fixing plate 1, a driving block 19 installed on the inner wall of one end of the clamping groove 16, and a threaded hole 20 opened at the center of the driving block 19.

[0027] Sample plates 6 are provided on the outer wall of the bottom of the pressing plate 10, the outer wall of one side of the clamping plate 18, and the outer wall of the fixing plate 1 at one end of the stabilizing screw 14. The pressing plate 10, the clamping plate 18, and one end of the stabilizing screw 14 are all in contact with the outer wall of the sample plate 6.

[0028] The inner wall of the threaded hole 20 is threaded with a threaded rod 21, the inner wall of the clamping groove 16 is slidably connected with a sliding block 17, the top outer wall of the sliding block 17 is fitted with a clamping plate 18, and one end of the threaded rod 21 contacts the outer wall of the sliding block 17.

[0029] The outer wall of one end of threaded rod 9 and threaded rod 21 is provided with insertion hole 22, and lever 23 is slidably connected in insertion hole 22. Lever 23 drives threaded rod 21 to rotate in threaded hole 20 on drive block 19. The rotation of threaded rod 21 pushes sliding block 17 and clamping plate 18 closer to the sample. Clamping plate 18 pushes one end of the sample into the outer wall of limit plate 7 to clamp the sample, which is convenient for fixing sample plate 6.

[0030] Both the clamping plate 18 and the limiting plate 7 have an "L" shaped cross section, and the bottom outer wall of the clamping plate 18 is slidably connected to the top outer wall of the fixing plate 1.

[0031] The stabilizing component 4 includes movable grooves 11 formed at both ends of the top outer wall of the fixed plate 1 and a mounting ring 12 installed on the top outer wall of the fixed plate 1 at one end of the movable grooves 11.

[0032] The fixing plate 1 has threaded grooves 13 on both the outer wall of the mounting ring 12 and the inner outer wall of the mounting ring 12. A stabilizing screw 14 is threadedly connected to the threaded groove 13. A knob 15 is welded to one end of the stabilizing screw 14. The knob 15 drives the stabilizing screw 14 to rotate in the threaded groove 13. As the stabilizing screw 14 rotates, it contacts the outer wall of the sample plate 6, fixing both sides of the sample plate 6, which facilitates fixation and improves the stability of the sample plate 6.

[0033] Working principle: In use, the fixing plate 1 is installed on the sample equipment through the mounting hole 2. The sample plate 6 is placed on top of the fixing plate 1, with one end of the sample plate 6 extending into the bottom of the limiting plate 7. The stabilizing screw 14 is rotated by the knob 15. The stabilizing screw 14 rotates in the threaded groove 13 at the mounting ring 12 and moves closer to each other in the movable groove 11. After the stabilizing screws 14 move closer to each other, they restrict the sample plate 6 to the center of the fixing plate 1. The lever 23 drives the threaded rod 9 to rotate, causing the pressing plate 10 to descend and fix the sample plate 6 in the fixing plate 1. The lever 23 drives the threaded rod 21 to rotate in the driving block 19. The threaded rod 21 pushes the clamping plate 18 to contact the outer wall of one end of the sample plate 6 through the sliding block 17, thus fixing the sample plate 6. This facilitates the fixing and support of the sample plate 6 in four opposite directions, preventing the sample plate 6 from tipping over, maintaining the safety of the experimental process, and facilitating the combined fixing of the sample.
