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