Embodiment
Below in conjunction with accompanying drawing, be described further:
A kind of electrical sheet thin plate tensile test apparatus, comprise on the sample in heating furnace 1, heating furnace 1 binder 3 under binder 2, sample, the upper connecting rod 4 being connected with binder on sample 2, the crossbeam 5 being connected with upper connecting rod 4, the holder 6 being connected with binder under sample 3, the motor cabinet 7 being connected with holder 6, is connected in the motor 8 on motor cabinet 7.On its sample, binder 2 is by the oval connecting hole 1 of processing on upper binding clasp base 9, upper binding clasp base 9, be connected in upper fixture block 1 on upper binding clasp base 9, be contained in bolt in oval connecting hole 1 and be connected on upper fixture block 2 12, upper fixture block 1 and the upper fixture block 2 12 on upper binding clasp base 9 bolt hole 1 of processing respectively and form with upper fixture block 1 merga pass that matches by being contained in bolt in oval connecting hole 1; Upper fixture block 1 and upper fixture block 2 12 connect by the bolt in bolt hole 1; Under sample, binder 3 is by the oval connecting hole 2 15 of processing on lower binding clasp base 14, lower binding clasp base 14, by being contained in the lower fixture block 1 on binding clasp base 14 under being connected in oval connecting hole 2 15, being contained in bolt in oval connecting hole 2 15 and being connected on lower fixture block 2 17, lower fixture block 1 and the lower fixture block 2 17 on lower binding clasp base 14 bolt hole 2 18 of processing respectively and forming with lower fixture block 1 merga pass that matches; Lower fixture block 1 and lower fixture block 2 17 connect by the bolt in bolt hole 2 18; On sample, binder 2 is identical with 3 structures of binder under sample and shape.
For preventing that skidding from appearring in sample in tension test, thus upper fixture block 1 and on process respectively anti-slip tank 1 on fixture block 2 12 opposite faces; Upper fixture block 1 and on process respectively anti-slip tank 2 20 on fixture block 2 12 opposite faces.
For ease of sample centering, install, upper fixture block 1 and/or on fixture block 2 12 opposite faces, and on lower fixture block 1 and/or lower fixture block 2 17 opposite faces, be provided with sample center sign 21.
