Therefore, the ultralow-temperature impact test device is simple in structure, easy to implement and reliable in data.
Description
Technical field
The present invention relates to a kind of impact test apparatus, particularly a kind of ultralow temperature impact test apparatus.
Background technology
Current 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, temperature minimum the reaching-120 ℃ of impulse test, cannot carry out ultralow temperature impulse test for the material using under ultralow temperature (196 ℃).Current 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.
Summary of the invention
The object of the invention is to overcome the technological deficiency of ultralow temperature impulse test, provide the one can cooling samples, again can cooling samples fixed station, can also measure the ultralow temperature impact test apparatus of sample low-temperature impact temperature.
The present invention is achieved through the following technical solutions:
A kind of ultralow temperature impact test apparatus, comprises impacting and supports and support, and described impact is provided with above supporting impacts blade and index dial, bottom is provided with hydraulic cylinder, described hydraulic cylinder top is connected with cooling bath, and described cooling bath top is provided with sample fixed station, in described cooling bath, is full of liquid nitrogen.
Preferably, described cooling bath is double-decker, and 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, on described sample fixed station, be provided with temperature sensor, temperature sensor is connected with temperature controller.
Preferably, on described impact blade, be provided with hook.
The present invention 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, in the time that specimen temperature reaches 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 after test plate (panel) and automatically raise pendulum thrusting to impact, go to next impulse test.
The present invention, by sample fixed station is cooling together with impact specimen, obtains the data of impulse test accurately of sample under ultralow temperature state, and the present invention is simple in structure, is easy to realize, and data are reliable.

Fig. 2 is the side view of the embodiment of the present invention;
1. hydraulic cylinder, the mouth of 2. finding time, 3. heat insulation layer, 4. cooling bath, 5. impacts and supports, 6. support, 7. impact specimen, 8. sample fixed station, 9. index dial, 10. hook, 11. impact blade.
Embodiment
Below in conjunction with specific embodiments and the drawings, the technical scheme in the embodiment of the present invention 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 support 5 tops and be provided with impact blade 11 and index dial 9, 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, in cooling bath 4, are full of liquid nitrogen.
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.
On sample fixed station 8, be provided with temperature sensor, temperature sensor is connected (not shown) with temperature controller, accurately the temperature of Control Assay.
Impact on blade 11 and be provided with hook 10, can play fixing effect.
Before doing impulse test, impact blade 11 have one 150 ° raise in advance angle, hydraulic cylinder 1 first drives cooling bath 4 to rise, sample fixed station 8 is immersed in the middle of liquid nitrogen cryogenics environment together with impact specimen 7, temperature controller can test samples temperature, and in the time that specimen temperature reaches testing requirements temperature, hydraulic cylinder 1 drives cooling bath 4 to decline, impact blade 11 declines and swing, utilize the kinetic energy impact sample 7 of potential energy conversion to impact.Impact the mode that the front potential energy of impact of blade 11 and the difference of the rear remaining potential energy of impact show on index dial 9, the absorption merit that obtains impacting test plate (panel).In the time that impact sample 7 carries out impulse test, record the Temperature numerical of temperature controller record simultaneously, just can obtain the impulse test numerical value of sample at this temperature.
Finish after 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 present invention adopt can oscilaltion cooling bath 4 cooling together with impact specimen 7 to sample fixed station 8, 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 professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to the multiple modification of these embodiment, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention 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.
