The device comprises an upper anti-rotation fixing plate, a magnetic slide block of the upper anti-rotation fixing plate, a lower anti-rotation fixing plate, and a magnetic slide block of the lower anti-rotation fixing plate, wherein, the curved surfaces of the upper and the lower anti-rotation fixing plates correspond to the excircle surfaces of clamps; the magnetic slide blocks are fixed at the side surface end parts of the two anti-rotation fixing plates respectively; the magnetic poles of the magnetic slide blocks on the anti-rotation fixing plates are opposite to each other; and the magnetic slide blocks are made of permanent-magnet material. The utility model solves the problems during fatigue test that buckle of the steel stranded wire gets loose, an upper clamp and a lower clamp rotate mutually, and the clamps are wound by hydraulic hoses, so as to effectively ensure smooth fatigue test of the steel stranded wire.
Description
Technical field
The utility model relates to a kind of anti-rotation device that is used for the steel strand wires torture test, belongs to the machine tool class.
Background technology
The device that carries out the metal material torture test is a fatigue tester, is also referred to as Material Testing Machine, as the MTS-810 Material Testing Machine of American MTS company.The method of utilizing fatigue tester to carry out the metal fatigue performance test in the prior art is: use the two ends clamping of two pairs of hydraulically operated fixtures of testing machine with sample, a pair of hydraulically operated fixture is connected with an axial hydraulic cylinder, control system is by the pressure of Control Shaft hydraulic oil in hydraulic cylinder, sample is applied periodic tensile force, with the mechanical property of check metal material under alterante stress, the i.e. fatigue behaviour of material.Because steel strand wires have many steel wires to reverse stranded forming, when in the torture test steel strand wires being applied for a long time periodic tensile force, the phenomenon that releases appears in steel strand wires, and originally stranded many steel wires closely fluff gradually, and causes two pairs of hydraulically operated fixtures of clamping sample to relatively rotate.The hydraulic hose that is connected with hydraulically operated fixture also rotates with anchor clamps, the situation that hydraulic hose twines anchor clamps occurs, and test can't be proceeded.
Summary of the invention:
The purpose of this utility model provides a kind of anti-rotation device that is used for the steel strand wires torture test and has solved the problem that releasing appears in the torture test steel strand wires, hydraulically operated fixture rotates mutually up and down, hydraulic hose twines anchor clamps, can guarantee carrying out smoothly of steel strand wires torture test effectively.
The technical solution of the utility model is: comprise the anti-rotation fixed head, last anti-rotation fixed head magnetic slider, following anti-rotation fixed head, following anti-rotation fixed head magnetic slider, the curved surface of upper and lower two anti-rotation fixed heads is corresponding with the anchor clamps periphery, magnetic slider is separately fixed at the side end of two anti-rotation fixed heads, and the magnetic pole of the magnetic slider on upper and lower two anti-rotation fixed heads is relative; Magnetic slider is a permanent magnetic material.
Installing on the anchor clamps of sample, upper and lower anti-rotation fixed head is being fixed on the periphery of hydraulically operated fixture with bolt.To go up the side end that anti-rotation fixed head magnetic slider is fixed on the anti-rotation fixed head with dormant bolt, to descend anti-rotation fixed head magnetic slider to be fixed on down the side end of anti-rotation fixed head with dormant bolt, upper and lower anti-rotation fixed head magnetic slider magnetic pole is relative, mutually near the time repel the frictional resistance in the time of can reducing magnetic slider effectively and slide mutually mutually.The anti-rotation fixed head that is connected with hydraulically operated fixture has prevented relatively rotating between upper and lower two hydraulically operated fixtures.
The beneficial effects of the utility model are: a kind of anti-rotation device that is used for the steel strand wires torture test adopts anti-rotation fixed head and the magnetic slider that has to the similar curved surface of anchor clamps periphery, solve the problem that releasing appears in steel strand wires in the torture test, hydraulically operated fixture rotates mutually up and down, hydraulic hose twines anchor clamps, can guarantee carrying out smoothly of steel strand wires torture test effectively.

Embodiment
The anti-rotation device that carries out the steel strand wires torture test with the MTS-810 fatigue tester is an example, and the making step of anti-rotation device is:
Referring to Fig. 3, Fig. 4 and Fig. 5, manufacture anti-rotation fixed head and following anti-rotation fixed head, use 2 block length 450mm, width 400mm, the steel plate bending of thickness 20mm becomes and the corresponding curved surface of anchor clamps periphery, and four limits polish, make anti-rotation fixed head 1 and following anti-rotation fixed head 4, make a call to the fixed orifice of three diameter 18mm on anti-rotation fixed head curved surface, make the screw of three M16 on the periphery of hydraulically operated fixture 6, its position is corresponding with three fixed orifices on the anti-rotation fixed head curved surface.Connect the position of magnetic slider in the side end of anti-rotation fixed head, make the screw of M5.Magnetic slider adopts length 30mm, width 20mm, the permanent magnetic steel of thickness 20mm and prefabricated counter sink will be gone up anti-rotation fixed head magnetic slider 2 with the bolt of M5 and be fixed on the side of anti-rotation fixed head 1, and following anti-rotation fixed head magnetic slider 3 is fixed on down on the side of anti-rotation fixed head 4.
Referring to Fig. 1 and Fig. 2, after installing steel strand wires sample 5 between upper and lower two hydraulically operated fixtures 6, to go up anti-rotation fixed head 1 and following anti-rotation fixed head 4 respectively and be connected on upper and lower two hydraulically operated fixtures 6 of clamping sample, anti-rotation fixed head magnetic slider 2 is contacted with following anti-rotation fixed head magnetic slider 3.
During torture test, upper and lower two hydraulically operated fixtures apply periodic tensile force to steel strand wires sample 5, under the effect of periodicity pulling force, the periodically deforming of length directions takes place in steel strand wires sample 5, between upper and lower two hydraulically operated fixtures apart from the generating period variation.The trend that steel strand wires sample 5 has " releasing " to reverse under the effect of pulling force.
Because upper and lower anti-rotation fixed head is fixedly connected on respectively on upper and lower two hydraulically operated fixtures, between last anti-rotation fixed head magnetic slider and following anti-rotation fixed head magnetic slider is that planar slide contacts, when sliding relatively between magnetic slider during torture test, avoid upper and lower two to press relatively rotating between anchor clamps effectively, therefore, solve the problem that releasing appears in steel strand wires in the torture test, hydraulically operated fixture rotates mutually up and down, hydraulic hose twines anchor clamps, can guarantee carrying out smoothly of steel strand wires torture test effectively.
