Description
Technical field
The utility model relates to a kind of tensile test equipment, is specifically related to a kind of automated imaging tension of steel strand testing machine.
Background technology
Existing tension of steel strand testing machine design all adopts extensometer to measure the extensibility of steel strand wires surrender section; Make the steel strand wires pretension through prestrain; The displacement extensometer is installed then, the extensometer upper and lower holder is clamped in respectively on the steel strand wires gauge length line, steel strand wires continue to be drawn the generation elongation at yield; Extensometer is measured the steel strand wires elongation, thereby obtains stress---the strain curve of surrender section.
Because steel strand wires disrumpent feelings moments can produce powerful quick-fried disconnected impulsive force; Not impaired for the protection extensometer, all, just extensometer is taken off steel strand wires after reaching yield strength during test, the extensibility to disrumpent feelings zone can only obtain through this mode of experiment with measuring machine crosshead displacement and steel strand wires are from yield point; There is following weak point in this technology: steel strand wires can produce powerful impulsive force in disrumpent feelings moment; Crossbeam also can produce and tremble, and makes displacement measurement produce than mistake, simultaneously; Steel strand wires are when fracture; Can have the reducing phenomenon of rupture, this reducing extension can be recorded in the steel strand wires elongation total amount, causes extensibility to increase illusion (it not is that steel strand wires rationally extend that reducing is extended).Prior art is the measurement of the extension to disrumpent feelings zone from yield point to steel strand wires; Owing to there is above-mentioned inevitable unfavorable factor; Be difficult to obtain true and reliable test findings; And being drawn of this zone stretches exactly that the extension of steel strand wires duty shows, and also is the important evidence of evaluation steel strand wires quality grade.
Therefore, for solving the problems of the technologies described above, necessary a kind of structure improved automated imaging tension of steel strand testing machine that has is provided, to overcome said defective of the prior art.
