Description
Technical field
The present invention relates to a kind of testing machine that detects the antitorque commentaries on classics cutting performance of tackifier, the antitorque commentaries on classics testing shear performance of the tackifier machine of the online detection moment of torsion of particularly a kind of energy, temperature and loading number of times.
Background technology
When tackifier used as cementing agent or coating, used tackifier was in being subjected to repeat shear loads process, and sample is normal because shear fatigue or torque overload cause between tackifier and the matrix peels off, and produces the interface unsticking and loses efficacy.Therefore, very necessity of limit static load performance is sheared in antitorque commentaries on classics shear fatigue performance and the antitorque commentaries on classics of measuring tackifier.
The domestic and international at present measurement to the tackifier anti-shear performance has various general and proprietary material testing machines, can reach accurate measurement.But these universal or special testing machines are limited to peel strength or the maximum shear strength of testing tackifier mostly, belong to limit static load and detect, and can not detect the anti-shearing fatigue behaviour of tackifier; The part test machine can only be used to study the anti-lateral shear performance of tackifier, and can not directly study the performance that the antitorque commentaries on classics of tackifier is sheared; In the present testing machine, loading force, moment of torsion and temperature that seldom can the real time record process of the test.Under different temperature (normal temperature and high temperature), the test of the antitorque commentaries on classics cutting performance of tackifier and metallic matrix (comprising antitorque commentaries on classics shear fatigue performance and antitorque commentaries on classics shearing limit static load performance) solves as yet fully.
" fluid sealant with by the method for testing of bonded substrate bonding sample interface shearing strength " (Chinese patent 20091002114.3) is disclosed to be a kind of testing machine of the maximum shear strength in interface when being exclusively used in test adhesive bonds plane." being used to test the Electromagnetic Drive fatigue tester of tackifier stretch-proof cutting performance " (Chinese patent 200720169626.0) is disclosed to be a kind of testing machine that is exclusively used in test stretch-proof fatigue of adhesive coating between two planes.The method and the test unit thereof of adhering material shearing performance " test " (Chinese patent 200610018601.0) is disclosed to be a kind of sample that is exclusively used in simulation when being subjected to principle stress and lateral stress, the testing machine of maximum shear strength in interface and tired shear resistance during test adhesive bonds plane.(Chinese patent 200910031760.8) is disclosed is a kind of sanitary filling field composite pad material that is used for testing " stacked ring type boxshear apparatus and to the method for testing composite liner material ", when applying different vertical loads, the transfer of the weakest slipping plane between different geotechnological material surface of contact in the sample." double-arm shear strength tester " (Chinese patent 200510017598.6) disclosed to be a kind ofly to bear curved compressive load by both arms, makes that clamped fibers cloth is stressed to remain unchanged, and realizes the shear resistance of fiber cloth is tested by plane shear.Above-mentioned testing machine all can not realize testing the antitorque commentaries on classics cutting performance of tackifier.Present invention can be implemented under normal temperature or the high temperature, detect antitorque commentaries on classics cutting performance between tackifier and the matrix, comprise antitorque commentaries on classics shear fatigue performance and antitorque commentaries on classics shearing limit static load performance.
Summary of the invention
The object of the invention is to provide a kind of testing machine that is used to test the antitorque commentaries on classics cutting performance of tackifier, this testing machine has overcome the unredeemed performance that detects the antitorque commentaries on classics shearing of tackifier under different temperatures of other testing machines, can destroy tackifier antitorque commentaries on classics shear fatigue under pulsating cyclic load or symmetrical cycle loading respectively, two indexs of antitorque commentaries on classics shearing overload destruction detect under the static load effect.Utilize taper bolt and the inner sleeve that has tapering to be exerted pressure in the adhesion interface in the pilot system; Charger drives the jaw rod member and realizes back and forth loading, thereby the bonding plane between the inside and outside sleeve is implemented torsional shear.When the tackifier shear failure that twists lost efficacy, inside and outside sleeve relatively rotates.The adjustable contact device that be connected on the inner sleeve this moment touches travel switch, and charger quits work.In the process of the test, data collecting card is with the detected taper bolt bearing pressure of pressure transducer, the detected loading number of times of photoelectric sensor, the detected temperature signal of temperature sensor, signals such as the detected driving torque of load transducer input industrial computer is noted.
The technical scheme that the present invention solves its technical matters employing is: the inside and outside sleeve that bonds together is fixed on the base by outer sleeve, and inside and outside sleeve is realized connecting by tackifier.Pilot system places high temperature furnace, but set environment temperature before the test.During the torsional shear torture test, drive the jaw rod member by the loading system that can realize back and forth loading inner sleeve is applied reciprocal moment of torsion.During the torsional shear overload test, drive the jaw rod member by loading system inner sleeve is applied the unidirectional moment of torsion that increases progressively.When producing relative motion between the inside and outside sleeve, adjustable contact device touches travel switch quits work loading system, and test stops.Data such as real time record load, loading number of times (torture test), temperature and moment of torsion in the process of the test.Secondly, taper bolt is exerted pressure to inner sleeve, and then make between the inside and outside sleeve bonding interface and produce pressure, realize tackifier is carried out antitorque commentaries on classics shearing performance test when bearing different pressures by adjusting gusset.This testing machine can carry out experimental test to the fatigue behaviour of tackifier under torsional shear stress under the different temperatures, simultaneously, also can use this testing machine and carry out under the different temperatures the quiet ultimate load under the tackifier torsional shear stress and carry out experimental test.
The invention has the advantages that the antitorque commentaries on classics cutting performance to tackifier under different temperatures detects the data that real time record is required.This testing machine structure is simple, easy to operate, can be used to detect the adhesive property of tackifier and metal or material such as nonmetal.
