Problems solved by technology

[0011] In the test process of the above-mentioned cantilever beam impact testing machine, in order to prevent the sample broken by the pendulum from flying out and hurting people, or the pendulum is loose and flying out and hurting people, no one is allowed to stand in the direction of the swing of the pendulum. Moreover, the average height of a person is about 1.8m, and the activity space occupied by the cantilever beam impact testing machine is the space in the direction of pendulum rotation, which occupies the activity space of the human body. Therefore, the test space required by the cantilever beam impact testing machine It is difficult to add the Izod impact testing machine in a limited room, and because of the short course time and the large number of students participating in the course at the same time, only individual students are allowed to operate the test in person, and other students can watch the test, so that it is impossible to allow more Students operate it by themselves, which violates the original intention of carrying out the experimental course to let students operate in the experiment and experience what they have learned

Embodiment 1

[0085] A material mechanics test device includes a casing, a sample placing mechanism, a hammer body placing mechanism, and a hammer body launching mechanism. The sample placement mechanism, the hammer body placement mechanism, and the hammer body launch mechanism are sequentially arranged in the casing from top to bottom.

[0086] Such as figure 2 As shown, the casing includes a top plate 1-1, a side plate, and a bottom plate 1-2. The side plates include a first side plate 1-3, a second side plate 1-4, a third side plate 1-5, and a fourth side plate 1-6 which are welded and fixed in sequence. The upper end of the first side plate 1-3, the upper end of the second side plate 1-4 and the upper end of the fourth side plate 1-6 are welded and fixed with the top plate 1-1, and the lower end of the first side plate 1-3 reaches the fourth side plate. The lower ends of the side plates 1-6 are welded and fixed to the bottom plate 1-2. In order to improve the stability of the casing...

Embodiment 2

[0136] This embodiment 2 is the same as embodiment 1, the difference is that, as Figure 18-20 As shown, in a kind of material mechanics test device of the present embodiment 2. In order to prevent the hammer body 3-1 from being damaged when the hammer body 3-1 falls, a buffer mechanism is also provided between the sample placement mechanism and the hammer body placement mechanism.

[0137] The buffer mechanism includes a third guide rod 5-1, a first buffer pad 5-2, a second buffer pad 5-3, an iron core 5-5, an armature 5-6, a switch, and a power supply.

[0138] The third guide rod 5-1 is provided with two side by side, and the two second guide rods 3-2 are located between the two third guide rods 5-1, and the hammer body 3-1 can move between the two third guide rods 5-1. Swipe up and down between -1. One end of the third guide rod 5-1 is welded and fixed to the second side plate 1-4, and one end of the third guide rod 5-1 away from the second side plate 1-4 is welded and f...

Abstract

The invention discloses a material mechanics test device and a using method thereof, and relates to the technical field of material mechanics tests. Including the casing, the sample placing mechanism, the hammer body placing mechanism, the hammer body launching mechanism, the height scale is arranged in the casing, the sample placing mechanism for clamping the sample, the hammer body placing mechanism for placing the hammer body, The hammer body launch mechanism used to launch the hammer body upwards and break the sample is connected with the casing sequentially from top to bottom. The present invention can reduce the space required for the impact toughness test.

Description

technical field [0001] The invention relates to the technical field of material mechanics testing, in particular to a material mechanics testing device and a method for using the same. Background technique [0002] Strength, plasticity, and toughness are the three basic mechanical properties of materials. For the detection of material toughness, impact toughness tests are indispensable. Impact toughness (a k ) is also called impact strength, which is the energy absorbed by the sample under impact load (called impact energy, with A K Indicated) divided by the area of ​​the sample section (indicated by S) obtained from the quotient. [0003] For the determination of the impact toughness of non-metallic materials such as hard plastics, glass fiber reinforced plastics, and ceramics, the test equipment used is a cantilever beam impact tester. Such as figure 1 As shown, the test principle of the Izod impact testing machine is as follows: [0004] ①Fix the lower end of the sam...
