Abstract
The utility model discloses a kind of impingement crackle sampling machine, comprise the pin be arranged on base, leg, support, rotating shaft, fork and pendulum, described fork is fixedly connected with integral with pendulum, described rotating shaft is through the upper end of fork, described fork and pendulum can be that axle center rotates with rotating shaft, thus realize swinging.Plastics batten is positioned on base, decontrols after lifting pendulum, pendulum falling impacts plastics batten to a certain extent after, the pin on base blocks pendulum lower end, makes plastics batten portion fractures, thus on plastics batten obtained crack tip.The utility model can obtain the impingement crack tip of the plastic material for observing, structure is simple, reasonable in design and manufacture simple, is conducive to promoting the use of.
Description
Technical field
The utility model belongs to the Crack Damage studying technological domain of material, specifically relates to a kind of impingement crackle sampling machine.
Background technology
Since the eighties in 20th century, the research based on the fracture behaviour of the plastic material of deformation and failure mechanism causes the extensive concern of people.At present, people obtain by observing the Detailed Experimental of crackle growth and fracture behaviour mostly for the research of deformation and breakoff phenomenon.The expansion of micro-crack controls the breakoff phenomenon of many macroscopic views, therefore, has great importance to the research of the Crack Extension behavior of plastic material material.The phenomenon that plastic material is impacted and ruptures happens occasionally, and the serviceable life of plastic products is shortened.The mechanism of plastic material impact fracture is worth studying, and observes the form of the crack tip of plastic material be a kind of method of the mechanism of research plastic material impact fracture under the microscope.But plastic material is subject to impulsive force and often breaks apart, the impingement crack tip sample that plastic material parts breaks to form is difficult to be obtained by the means and methods of routine.Therefore, be necessary to design a kind of can obtain plastic material for observing impingement crack tip, structure is simple, reasonable in design and manufacture simple impingement crackle sampling machine.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of impingement crackle sampling machine is provided, its structure is simple, reasonable in design and manufacture is simple, low cost of manufacture, effectively can prepare the impingement crack tip sample of plastic material, to carry out observational study to the crack tip expansion pattern of plastic material.
For achieving the above object, the technical solution adopted in the utility model is: a kind of impingement crackle sampling machine, it is characterized in that: comprise the pin be arranged on base, leg, support, rotating shaft, fork and pendulum, described fork is fixedly connected with integral with pendulum, described rotating shaft is through the upper end of fork, described fork and pendulum can be that axle center rotates with rotating shaft, thus realize swinging, and described base, pin, support, leg are fixedly connected with integral, stage casing is positioned on base with the plastics batten of V-notch, the V-notch of plastics batten is back to pendulum, pedestal lower end is close in plastics batten both end sides face, decontrol after lifting pendulum, pendulum and fork are that axle center rotates the V-notch back side of falling impacts to plastics batten with rotating shaft, cause the crack tip that V-notch forms expansion, Charpy impact plastics batten to a certain extent after, pin on base blocks pendulum lower end, make pendulum plastics batten can not be impacted brisement, and be portion fractures, the impingement crack tip of expansion is formed at the V-notch of plastics batten, the form of this crack tip is observed by microscope, thus can study the Crack Damage expansion mechanism of plastic material.
Above-mentioned a kind of impingement crackle sampling machine, is characterized in that: described base, pin, leg, support, rotating shaft, fork and pendulum are metal material.
The utility model compared with prior art has the following advantages: 1, the utility model adopts pin to block pendulum lower end, to control the degree of Charpy impact plastics batten, make pendulum plastics batten can not be impacted brisement, and be portion fractures, form the crack tip of expansion at the V-notch of plastics batten, thus the impingement crack tip for observing can be obtained.
2, the utility model can obtain the impingement crack tip sample of plastic material, for observing and study the impact injury expansion mechanism of crackle, compensate for plastic material and is subject to impulsive force and often breaks apart and the deficiency that can only observe rupture surface.
3, the utility model structure is simple, reasonable in design and manufacture simple, is conducive to promoting the use of.
Below by drawings and Examples, the utility model is described in further detail.

Embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model comprises the pin 7 be arranged on base 1, leg 6, support 5, rotating shaft 4, fork 3 and pendulum 2, described fork 3 is fixedly connected with integral with pendulum 2, described rotating shaft 4 is through the upper end of fork 3, described fork 3 and pendulum 2 can with rotating shaft 4 for axle center rotate, thus realize swinging, described base 1, pin 7, support 5, leg 6 are fixedly connected with integral.
In the present embodiment, described base 1, pin 7, leg 6, support 5, rotating shaft 4, fork 3 and pendulum 2 are metal material.
Principle of work of the present utility model is: during use, stage casing is positioned on base 1 with the plastics batten 8 of V-notch, the V-notch of plastics batten 8 is back to pendulum 2, support 5 lower end is close in the side, two ends of plastics batten 8, decontrol after lifting pendulum 2, pendulum 2 and fork 3 with rotating shaft 4 for axle center rotates the V-notch back side of falling impacts to plastics batten 8, cause the crack tip that V-notch forms expansion, pendulum 2 impact plastics batten 8 to a certain extent after, pin 7 on base 1 blocks pendulum 2 lower end, make pendulum 2 plastics batten 8 can not be impacted brisement, and be portion fractures, the crack tip of expansion is formed at the V-notch of plastics batten 8, the form of this crack tip is observed by microscope, thus can study the Crack Damage expansion mechanism of plastic material.
