Technical field
The utility model relates to a kind of material properties test equipment, particularly a kind of rupture strength test unit.
Background technology
Rupture strength is that material can bear measuring of peak load when being subjected to external force crooked, is one of important indicator of various material tests.Shape shown in Figure 1 is present rupture strength equipment commonly used when detecting, it comprises support cylinder and bearing, support cylinder and bearing are manufactured to a unified integral body, can't carry out any adjustment, therefore, distance immobilizes between two support cylinder, in use for some time, support cylinder can diminish because of wearing and tearing, exceeds equipment size and allows usable range, makes testing result inaccurate; And support cylinder also can't be dismantled, and therefore must change together with bearing.
In addition, owing to antagonism folding grip size in rupture strength detects requires very strict: wherein the diameter requirement to loading cylinder and support cylinder is nominal diameter 10 ± 0.1mm for manufacturing dimension, and the size that the wearing and tearing back allows only is nominal diameter 10-0.2mm, and two support cylinder center distance can only be nominal size 100 ± 0.1mm.From above-mentioned requirements, as can be seen, the wear range that support cylinder allows is very little, in this case, for guaranteeing to obtain test findings accurately, may change testing equipment continually, and it is higher to detect cost.
The utility model content
The technical problems to be solved in the utility model just is: at the technical matters that prior art exists, the utility model provides a kind of two support cylinder center distance can adjust, can change separately support cylinder, long service life, low, simple in structure, the easy rupture strength test unit of installation of cost.
For achieving the above object, rupture strength test unit of the present utility model, comprise support cylinder, bearing, support cylinder is fixed on the bearing top by web member, its particular location can be adjusted according to the actual conditions of test specimen and the abrasion condition of support cylinder when installing or test, and support cylinder can also be rotated.
Preferably, above-mentioned web member is connected on the bearing by fastener.
Preferably, above-mentioned web member is welded on the bearing.
Preferably, above-mentioned bearing is " L " shape structure.
As further improvement of the utility model, the rupture strength test unit also comprises a base, and above-mentioned bearing is fixed on the base by securing member, and at least 2 bearings are installed on the above-mentioned base.
Further, above-mentioned base is provided with " T " font chute for erection support, and above-mentioned securing member is bolt, and bolt head is arranged in chute, and screw rod is fixed on the bearing.
Further, the quantity of above-mentioned bearing and chute all is at least 2.
The utlity model has following advantage:
1, support cylinder of the present utility model can be adjusted in the installation site at bearing top, makes that the distance between two support cylinder can be adjusted, and applicability is stronger, and can guarantee the accuracy of the rupture strength value of test;
2, because support cylinder is detachable and rotate, therefore can rotate and make the wearing and tearing of support cylinder cylinder evenly, can increase the serviceable life of support cylinder; Can the cylinder of support cylinder be quenched simultaneously, carburizing, nitriding, cross processing such as chromium, increase the wearing quality of support cylinder;
3, support cylinder of the present utility model is detachable, during the support cylinder serious wear, can only change support cylinder, and needn't change bearing, can effectively reduce cost.

Embodiment
Below with reference to Figure of description and specific embodiment the utility model is described in further details.
As shown in Figure 2, rupture strength test unit of the present utility model, comprise support cylinder 1, bearing 2, support cylinder 1 is fixed on bearing 2 tops by web member 25, its particular location can be adjusted according to the actual conditions of test specimen and the abrasion condition of support cylinder 1 when installing or test, as: the wearing and tearing of two support cylinder 1 make the center distance between it surpass allowed band, the installation site of then adjusting bearing 2 makes that corresponding two support cylinder 1 are more close on two bearings 2, to reduce center distance.Above-mentioned web member 25 is such as but not limited to connecting rod.Support cylinder 1 is rotatable, and bearing 2 is " L " shape structure; Web member 25 is connected on the bearing 2 by fastener, also can be welded on the bearing 2, also can adopt other dismountable modes to be fixedly mounted on bearing 2 tops, can specifically select fixed form according to the test demand in concrete the application, mounting hole when wherein mounting hole 21 is web member 25 employing fasteners installations, as adopt modes such as welding to connect, and mounting hole 21 can be set, above-mentioned fastener is for example but do not comprise bolt, screw, rivet.In the present embodiment, because the installation site of bearing 2 can be adjusted, make that the distance between two support cylinder 1 can be adjusted, so its applicability is stronger, can also guarantees the accuracy of the rupture strength value of testing; In addition, because support cylinder 1 is detachable and rotate, therefore can rotates and make the wearing and tearing of support cylinder 1 cylinder evenly, increase the serviceable life of support cylinder 1; Can quench to each surface of support cylinder 1 simultaneously, carburizing, nitriding, cross processing such as chromium, increase the wearing quality of support cylinder 1; At last, during support cylinder 1 serious wear, can only change support cylinder 1, and needn't change bearing 2, can effectively reduce cost.
As shown in Figure 3, on the basis of embodiment 1, rupture strength test unit in the present embodiment, also comprise a base 3, above-mentioned bearing 2 is fixed on the base 3 by securing member, this securing member can wherein fixedly have at least two bearings 2 for securing member commonly used such as bolt, screw, rivet on the base 3, the particular location of bearing 2 can be adjusted according to the test demand.
As Fig. 3, Fig. 4 and shown in Figure 5, on the basis of embodiment 2, two " L " shape bearings 1 are installed on the base 3 in the present embodiment at least, two " L " shape bearings are installed dorsad relatively, and base 3 is provided with two " T " font chutes 4, is used for installing above-mentioned two bearings 2, above-mentioned securing member 7 is bolt, during installation, bolt head 71 is installed in the chute 4, screw rod is fixed on the bearing 2.
