Abstract
The utility model discloses a special chuck for magnesium alloy sheet tensile tests. The chuck comprises two corresponding clamping units, wherein one clamping unit is provided with at least one through hole and the other clamping unit is provided with through holes or blind holes corresponding to the through holes; threads are arranged in the blind holes. The chuck has the beneficial effects that the chuck clamps magnesium alloy sheets firmly and reliably and smaller stress is concentrated on the clamped parts, so that the clamping requirement in the magnesium alloy sheet tensile tests can be better met, thus improving the credibility of the test results.
Description
Technical field
The utility model relates to a kind of magnesium alloy sheet tension test special carrier.
Background technology
Magnesium alloy materials has the features such as density is little, lightweight, wearing quality is good, thermal diffusivity is good than aluminium alloy, is with a wide range of applications, as can be applicable to automotive hub, frame of handwheel, notebook computer casing, automobile panel etc. at engineering field; But meanwhile, the chemical property of magnesium alloy is more active, especially burning-point is lower, its warm forming process is more restive, mainly take at present casting and plastic forming as main, therefore becomes study hotspot, in magnesium alloy sheet plastic forming field, bias toward it is carried out to warm tension test, by changing the parameters such as draft temperature, draw speed, carry out the mechanical property of test material, thereby provide fundamental basis for the plastic forming of Mg alloy thin wall part.But because magnesium alloy sheet chuck by standard configuration on conventional universal testing machine is relatively difficult to firm grip, to test findings, bring relatively large deviation, the confidence level of test findings is not high.
Summary of the invention
The purpose of this utility model is to provide a kind of magnesium alloy sheet tension test special carrier using on universal testing machine, and this chuck is solid and reliable to the clamping of magnesium alloy sheet, thereby can improve the confidence level of test findings.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A tension test special carrier, described chuck is comprised of two grip unit of mutual correspondence, and a grip unit has at least one through hole, and another grip unit has corresponding with it through hole or blind hole, in described blind hole, has screw thread.The utility model in use, two grip unit will be held test specimen and be clamped in middle, has opened and through hole or the corresponding hole of blind hole in grip unit corresponding position, test specimen holding portion, like this, two grip unit can will be held the solid and reliable clamping of test specimen by bolt, and retained part stress is concentrated less, easy to operate, can better meet the tension test clamping needs of magnesium alloy sheet, thereby improve the confidence level of test findings.
As improvement of the present utility model, a grip unit has two through holes, another grip unit has two blind holes or through hole, be bolted two groups of mutual corresponding through hole and blind holes or be bolted two groups of through holes of correspondence mutually, being held test specimen is more firmly clipped in the middle by described two grip unit, rotation can be do not produced, the tension test clamping needs of magnesium alloy sheet can be better met.
As further improvement of the utility model, the diameter of each through hole is 10mm.Like this, be conducive to chuck clamping to carry out tension test in universal testing machine standard cartridge.
As of the present utility model, further improve, the shape of the chuck that described two grip unit form is cylindrical or rectangle or ellipse.These several shapes are more conducive to dormant bolt and connect tensile test specimen, can fall stress concentration, better meet the tension test needs of magnesium alloy sheet, thereby improve the confidence level of test findings.
In sum, the beneficial effects of the utility model are: this chuck is solid and reliable to the clamping of magnesium alloy sheet, and retained part stress is concentrated less, can better meet the tension test clamping needs of magnesium alloy sheet, thereby improve the confidence level of test findings.
Accompanying drawing explanation
Fig. 1 is that the utility model is used view.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Embodiment 1, and as shown in Figure 1, the utility model is paired use in use, and whole tension test test specimen is comprised of upper and lower two chucks and tensile test specimen 3.In the grip unit 1 of upper end chuck, get out two through holes, in upper end grip unit 2, get out the interior threaded blind hole corresponding with grip unit 1, in test specimen 3 holding portions, upper end, get out the through hole corresponding with grip unit 1 and grip unit 2, so that the blind hole on the through hole in grip unit 1, grip unit 2, the through-bore axis on test specimen 3, on same straight line, firmly connect described two chucks and test specimen 3 with M8 dormant bolt.Lower end chuck and lower end are held test specimen and copy upper end chuck and upper end to be held test specimen boring, with M8 dormant bolt, firmly connect described two chucks and test specimen 3, then chuck clamping are carried out to tension test in universal testing machine standard cartridge.
Embodiment 2, in the present embodiment, the structure of chuck is substantially the same manner as Example 1, institute's difference is, grip unit 1 has two through holes, grip unit 2 has corresponding with it through hole, on test specimen 3, get out the through hole corresponding with grip unit 1 and grip unit 2, so that the through hole in grip unit 1, through hole in grip unit 2, through-bore axis on test specimen 3 is on same straight line, with M8 dormant bolt, firmly connect described two chucks and test specimen 3 again, then chuck clamping is carried out to tension test in universal testing machine standard cartridge.
