Technical Field
The utility model belongs to the technical field of the material tensile test, a rubber tensile test frock is related to.
Background
In the process of rubber tensile test, a dumbbell-shaped rubber sample needs to be clamped on a universal material tensile machine, tensile test is carried out at a certain tensile rate, and finally the tensile strength and the elongation at break of the rubber are obtained. In the process of holding a dumbbell specimen, it is necessary to have the specimen in the middle of the tensile machine holder to ensure accurate tensile strength and elongation at break. If the sample is skewed during the clamping process, the resulting tensile strength and elongation at break will vary somewhat. At present, the sample is usually held manually according to personal experience, and the probability of the sample being skewed is high. In order to ensure the accuracy of the rubber tensile test result, it is extremely important to ensure that the sample is in the middle position of the tensile machine holder when being held.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a rubber tensile test frock in order to overcome the defect that above-mentioned prior art exists for avoid making the crooked relatively poor problem that leads to the tensile test result accuracy of sample because of artifical centre gripping.
The purpose of the utility model can be realized through the following technical scheme:
a rubber tensile test tool comprises a bottom plate and a fixing groove formed in the bottom plate;
the size of the fixing groove is matched with the size of a rubber sample strip to be tested, the rubber sample strip is fixed on the tool through the fixing groove, and the rubber sample strip is located in the middle of 2 fixing clamps during tensile testing.
Further, the bottom plate is a cuboid bottom plate.
Furthermore, the width of the bottom plate is consistent with the size of the clamp, so that when the tool moves to the two sides of the bottom plate in the width direction and is flush with the edges of the two sides of the clamp, the positioning of the rubber sample strip can be completed.
Furthermore, the fixing grooves are formed in the top surface of the bottom plate and are symmetrically arranged along the symmetry axis of the top surface in the length direction and the symmetry axis of the top surface in the width direction, namely after the bottom plate is positioned, the rubber sample strip is positioned in the middle of the clamp.
Furthermore, the fixing grooves penetrate through two sides of the bottom plate in the length direction.
Furthermore, the length of the fixing groove is smaller than that of the rubber sample strip, so that after the rubber sample strip is fixed to the fixing groove, two ends of the rubber sample strip are respectively exposed out of the tool so as to be clamped and fixed by the clamp.
Further, the thickness of the fixing groove is not more than that of the rubber sample strip, so that the rubber sample strip can be taken out before the tensile test is started.
Furthermore, the rubber sample strip is a dumbbell-shaped sample, the fixing groove is a dumbbell-shaped groove, and the rubber sample strip is fixed through the dumbbell-shaped fixing groove.
The test method for the rubber tensile test of the tool comprises the following steps:
1) installing a rubber sample strip in a fixed groove on a tool, and adjusting the relative positions of 2 clamps of the tensile testing machine;
2) pushing the bottom plate between the 2 clamps along the width direction to enable two sides of the bottom plate in the width direction to be flush with edges of two sides of the clamps, so that the rubber sample strip is located in the middle of the clamps;
3) adjusting the clamp and respectively clamping two ends of the rubber sample strip;
4) and removing the tool, starting the tensile testing machine, and performing tensile test to obtain tensile property data such as the rubber tensile strength, the elongation at break and the like of the rubber sample strip.
The tool is used for installing and positioning the rubber sample strip on a clamp of a tensile testing machine, symmetrically fixing the rubber sample strip on a bottom plate through a fixing groove, and enabling two ends of the rubber sample strip to extend out of the fixing groove so as to be clamped by the clamp; the width of the bottom plate on the tool is consistent with the size of the clamp, and in the process of installing and positioning the rubber sample strip, when the tool is completely coincided with the width of the clamp, namely, the two sides of the width of the bottom plate are flush with the edges of the two sides of the clamp, the rubber sample strip is fixed in the middle of the clamp, so that the problem that the accuracy of a test result is poor due to the fact that a sample is inclined due to manual clamping is avoided.
Compared with the prior art, the utility model has the characteristics of it is following:
1) the accuracy is high: the rubber tensile sample is fixed through the tool, so that the sample deflection caused by manual clamping is avoided, and the accuracy of a test result is improved;
2) the normative is good: through the tool, the operation of clamping the sample is further standardized, and the possibility of generating operation irregularity due to testing by different personnel is reduced;
3) time is saved: the fixture can ensure that the sample is clamped in place at one time, reduces the repeated operation of clamping the sample due to the deflection of the sample, and saves the test time.
