Detailed implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , an impact test device for the research and development of high-performance steel, including a timing placement mechanism, an impact test mechanism, and a protection mechanism. The timing placement mechanism includes a setting frame 1. A limiting groove 2 is opened inside the setting frame 1. A bidirectional threaded rod 3 is rotatably connected inside the limiting groove 2. A moving block 4 is arranged outside the bidirectional threaded rod 3. A placing seat 5 is fixedly connected to the upper side of the moving block 4. A pressure sensor 6 is fixedly installed inside the placing seat 5. A first set screw 7 is arranged inside the moving block 4. A setting groove 8 is opened on one side surface of the setting frame 1. The upper side of the setting frame 1 is fixedly connected with a mounting frame 9 by screws. A time delay relay 10 is fixedly installed on one side of the mounting frame 9. The pressure sensor 6 is electrically connected to the time delay relay 10. A placing groove 11 is opened inside the setting frame 1. One end of the bidirectional threaded rod 3 is fixedly connected with a turning handle 12. The bidirectional threaded rod 3 is threadedly connected to the moving block 4. The moving block 4 is slidably connected to the limiting groove 2. The first set screw 7 is threadedly connected to the moving block 4. Inside the setting frame 1, the bidirectional threaded rod 3 can be rotated by the turning handle 12. The rotation of the bidirectional threaded rod 3 causes the moving block 4 threadedly connected thereto to slide in the limiting groove 2, thereby adjusting the position of the placing seat 5. The first set screw 7 inside the moving block 4 is used to fix the position of the moving block 4, so that the positions of the two placing seats 5 can be adjusted according to the size of the high-performance steel. The high-performance steel sample to be tested is placed on the placing seat 5. The weight of the sample will act on the pressure sensor 6 inside the placing seat 5. After the pressure sensor 6 senses the pressure of the sample, it transmits a signal to the time delay relay 10. The time delay relay 10 automatically starts the impact test mechanism after a set time according to the preset time delay, so that the impact test can be automatically started.

[0021] In one aspect of this embodiment, after the time-delay relay 10 starts the motor 13, its output drives the swing arm 14 to rotate. The pendulum 15 outside one end of the swing arm 14 obtains kinetic energy as the swing arm 14 rotates. During the movement of the pendulum 15, since it is slidably connected to the swing arm 14 and its position is fixed by the second set screw 16, it can be ensured that the impact is performed at a suitable time with a predetermined trajectory and speed. When the pendulum 15 completes the impact, the impact result will be displayed on the dial 18 fixed at one end of the sleeve 17.

[0022] In one aspect of this embodiment, the rubber pad 20 fixedly connected to the lower side of the bottom plate 19 contacts the position where the device is placed. Through the cooperation of the rubber pad 20 and the notch 21, the device can be placed more stably and is not prone to sliding. During the test, the protection plate 23 connected to the connecting block 22 on one side of the placement seat 5 can provide protection for the operator and reduce potential hazards.

[0023] Working principle of the present utility model: When the impact test device for the research and development of high-performance steel is in use, the bidirectional threaded rod 3 can be rotated by turning the handle 12. The rotation of the bidirectional threaded rod 3 causes the moving block 4 threadedly connected thereto to slide in the limiting groove 2, thereby adjusting the position of the placement seat 5. The first set screw 7 inside the moving block 4 is used to fix the position of the moving block 4, so that the positions of the two placement seats 5 can be adjusted according to the size of the high-performance steel. The high-performance steel sample to be tested is placed on the placement seat 5, and the weight of the sample acts on the pressure sensor 6 inside the placement seat 5. After the pressure sensor 6 senses the pressure of the sample, it transmits a signal to the time-delay relay 10. After a set time delay according to the preset time, the motor 13 starts, and its output drives the swing arm 14 to rotate. The pendulum 15 outside one end of the swing arm 14 obtains kinetic energy as the swing arm 14 rotates. During the movement of the pendulum 15, since it is slidably connected to the swing arm 14 and its position is fixed by the second set screw 16, it can be ensured that the impact is performed at a suitable time with a predetermined trajectory and speed. When the pendulum 15 completes the impact, the impact result will be displayed on the dial 18 fixed at one end of the sleeve 17. In this solution, all electrical equipment is powered by an external power supply.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
