Abstract
The utility model relates to a gauge length internal strain measuring device for a thin-wall tube high-temperature tensile test, belonging to the technical field of high-temperature material mechanical test devices. An upper V-shaped knife edge clamp is hinged through a bolt 1 at the front end; an upper stress application claw beam is respectively and fixedly connected with the upper V-shaped knife edge clamp; two ends of an upper tension spring are connected with the upper stress application claw beam; a lower V-shaped knife edge clamp is hinged through a bolt 2 at the front end, a lower stress application claw beam is respectively and fixedly connected with the lower V-shaped knife edge clamp; two ends of a lower tension spring are connected with the lower stress application claw beam; and an extensometer is fixedly connected with the upper stress application claw beam and the lower stress application claw beam. The measuring device has the advantages of having novel structure, solving measurement of deformation of the thin-walled tube under high temperature, and providing accurate and fast means for the thin-walled tube high-temperature mechanics performance testing and research.
Description
Technical field
The utility model belongs to high-temperature material mechanical testing equipment technical field.
Background technology
For the extensometer that is installed, process convex shoulder at the sample marking distance place on high-temperature short delay stretching or the high-temerature creep sample.Yet, during the thin-wall pipes drawing by high temperature, along with axial elongation, it is radially also dwindling, and pipe outer surface do not allow to weld condiment, so the fixing claw of extensometer, just can't carry out the gauge length internal strain and measure, become in the domestic and international high temperature tubing test and will solve a problem.
Summary of the invention
The utility model provides a kind of thin-wall pipes high temperature tension test with gauge length internal strain measurement mechanism, to solve at present the fixedly claw of extensometer, can't carry out the problem that the gauge length internal strain is measured.The technical scheme that the utility model is taked is: it is hinged by the bolt one of front end to go up V-knife mouth clip, goes up afterburning claw beam and fixedlys connected with last V-knife mouth clip respectively, and last extension spring two ends are connected with last afterburning claw beam; Following V-knife mouth clip is hinged by the bolt two of front end, and following afterburning claw beam is fixedlyed connected with following V-knife mouth clip respectively, and the tension spring two ends are connected with following afterburning claw beam; Extensometer is fixedlyed connected with following afterburning claw beam with last afterburning claw beam.
, on sample marking distance, more afterburning claw beam 2 is drawn outside the stove from the high temperature furnace side with V-knife mouth 1 clip, at room temperature tie with extension spring; After the hot test, the sample axial elongation reached outside the stove through extensometer 4 by clip, and sample diameter in elongation will dwindle, but because the effect of extension spring is clamped on clip on the sample all the time, can not producing skids waits malfunction, guarantees to test successfully.
Advantage of the present utility model is: novel structure, solved the measurement that thin walled tube is out of shape under hot environment, and for thin-wall pipes mechanical behavior under high temperature test and research, provide both accurate, again means efficiently.
