According to the utility model, an impact test board and the test sample fixing platform are cooled by utilizing the ultralow temperature performance of the liquid nitrogen; the temperature of a test sample is controlled by a temperature controller; and when the temperature of the test sample achieves the required temperature of the test, the low-temperature groove is moved downwards and the absorbing energy of the impact test board is obtained in a way of displaying the difference between the potential energy before the impact and the residuary potential energy after the impact of the impact blade on the dial. The device provided by the utility model is simple in structure, easy to achieve and reliable in data.
Description
Technical field
The utility model relates to a kind of impact test apparatus, particularly a kind of ultralow temperature impact test apparatus.
Background technology
Present impact test apparatus used divides normal temperature impact test apparatus and low-temperature impact test device, traditional low-temperature test device adopts the freezing sample of compressor cooling, the temperature of impulse test is minimum reaches-120 ℃, can't carry out the ultralow temperature impulse test for the material that uses under ultralow temperature (196 ℃).Present also useful liquid nitrogen container cooling samples is carried out low-temperature impact test, but because crucible tongs and the sample fixed station of folder sample are uncolled, causes test figure inaccurate, can not truly reflect the performance of metal material in ultralow temperature (196 ℃) situation.
The utility model content
The purpose of this utility model is to overcome the technological deficiency of ultralow temperature impulse test, provide a kind of can cooling samples, again can the cooling samples fixed station, can also measure the ultralow temperature impact test apparatus of sample low-temperature impact temperature.
The utility model is achieved through the following technical solutions:
A kind of ultralow temperature impact test apparatus comprises impacting and supports and support that described impact is supported the top and is provided with impact blade and index dial, the bottom is provided with hydraulic cylinder, described hydraulic cylinder top is connected with cooling bath, is provided with the sample fixed station above described cooling bath, is full of liquid nitrogen in described cooling bath.
Preferably, described cooling bath is double-decker, and the cooling bath intraformational bed is filled by aluminium foil and the compound heat insulation layer of low temperature glass fibrous paper.
Preferably, the mouth of finding time is set on cooling bath.
Preferably, be provided with temperature sensor on described sample fixed station, temperature sensor is connected with temperature controller.
Preferably, be provided with hook on described impact blade.
The utility model utilizes the ultralow temperature performance (196 ℃) of liquid nitrogen, impact test plate (panel) and sample fixed station carry out cooling, by temperature controller, specimen temperature is controlled, when specimen temperature reaches the testing requirements temperature, move down cryostat,, utilize the mode that after impacting the front potential energy of blade impact and impacting, the difference of remaining potential energy shows on scale, obtain impacting the absorption merit of test plate (panel), impact blade utilization hook induced effect and automatically raise pendulum after thrusting the impact test plate (panel), go to next impulse test.
The utility model obtains the data of impulse test accurately of sample under the ultralow temperature state by sample fixed station and impact specimen is cooling together, and the utility model is simple in structure, is easy to realize, data are reliable.

Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the side view of the utility model embodiment;
1. hydraulic cylinder, the mouth of 2. finding time, 3. heat insulation layer, 4. cooling bath, 5. impact and support, 6. support, 7. impact specimen, 8. sample fixed station, 9. index dial, 10. hook, 11. impact blades.
Embodiment
Below in conjunction with specific embodiments and the drawings, the technical scheme in the utility model embodiment is clearly and completely described.
Ultralow temperature impact test apparatus as illustrated in fig. 1 and 2, comprise and impact support 5 and support 6, impact is supported 5 tops and is provided with impact blade 11 and index dial 9, the bottom is provided with hydraulic cylinder 1, hydraulic cylinder 1 top is connected with cooling bath 4, cooling bath 4 tops are provided with sample fixed station 8, are full of liquid nitrogen in cooling bath 4.
The cooling bath 4 of the present embodiment is double-decker, and cooling bath 4 intraformational beds are filled by aluminium foil and the compound heat insulation layer 3 of low temperature glass fibrous paper, reduces and conducts heat, and the mouth 2 of finding time is set on cooling bath 4.
Be provided with temperature sensor on sample fixed station 8, temperature sensor is connected (not shown) with temperature controller, accurately the temperature of Control Assay.
Impact being provided with hook 10 on blade 11, can play fixing effect.
Before doing impulse test, impact blade 11 have one 150 ° raise in advance the angle, hydraulic cylinder 1 first drives cooling bath 4 and rises, make sample fixed station 8 be immersed in the middle of the liquid nitrogen cryogenics environment together with impact specimen 7, temperature controller can the test samples temperature, and when specimen temperature reached the testing requirements temperature, hydraulic cylinder 1 drove cooling bath 4 and descends, impact blade 11 declines and swing, utilize the kinetic energy impact sample 7 of potential energy conversion to impact.The mode that after the front potential energy of impact of impact blade 11 and impact, the difference of remaining potential energy shows on index dial 9, the absorption merit that obtains impacting test plate (panel).When impact sample 7 carries out impulse test, record simultaneously the Temperature numerical of temperature controller record, just can obtain the impulse test numerical value of sample at this temperature.
After finishing the impulse test of an impact specimen, impact blade 11 and utilize hook 9 induced effect to raise pendulum to initial position, go to next impulse test.
The utility model adopt can oscilaltion 4 pairs of sample fixed stations 8 of cooling bath and impact specimen 7 cooling together, obtain the impulse test accurate data under ultra-low temperature surroundings, simple in structure, easy to operate, data are true and reliable.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
