Description
Technical field
The present invention relates to metal material detection technique field, relate in particular to a kind of sample tension corrosion testing machine.
Background technology
In commercial production, need to carry out the tension corrosion test for the key position of some products with material.As be applied in sleeper beam on " motor-car ", be the critical piece of " motor-car " assembling vehicle, need high-strength, can weld, corrosion resistant 7N01 alloy, before assembling, must detect its corrosion resistance.Stress corrosion (cracking) test body used was long-pending huge, expensive, complicated in the past.As shown in Figure 1, it adopts the lever principle loading tensile, due to arm of force error, directly affects the size of moment, and three axle center friction force is along with the prolongation of time, and drag size is also in continuous variation, and the difference of degree of lubrication also can affect experiment effect.In addition, apply the verticality of power, also can vary with each individual, all these obviously exist a lot of uncertain factors.Therefore, acquired results also will carry out the revision of the convention, and what are proper for the revision of the convention, also there is no specified standard in conclusive, standard, exists dispute in actual testing, and both sides of supply and demand also must exist difference.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of sample tension corrosion testing machine is provided.More reasonably to test structure, improve the sample testing precision.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of sample tension corrosion testing machine, comprise support, corrosion cup, counterweight, upper towbar and lower towbar, it is characterized in that, described support comprises crossbeam, the upper end of described upper towbar is connected with described crossbeam, the lower end is connected with described sample, the upper end of described lower towbar is fixedly connected with the bottom of described corrosion cup, the lower end is provided with the counterweight seat, described counterweight is piled up on the counterweight seat, and glass end of described corrosion cup is provided with sample holding device.
The invention has the beneficial effects as follows: external force of the present invention is by corrosion cup, corrosive liquid and counterweight, the gravity that the three adds up is exactly proof stress, within this stress is applied directly to sample marking distance, on working portion, interspersed intermediate link, also need not consider the impact of frictional resistance and the foeign elements such as arm of force moment and angle of inclination, therefore, it detects data accurately, reliably.Different alloy samples can be regulated by weights, and is easy to use.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described corrosion glass top also is provided with the safety rope that is fixedly connected with described crossbeam.
Adopt the beneficial effect of above-mentioned further scheme to be, after sample fracture, safety rope plays interim lifting effect, can not cause the corrosion cup to topple over.
Further, described support also comprises the column that is supported on described crossbeam two ends, and the lower end of described column is provided with leg.
Adopt the beneficial effect of above-mentioned further scheme to be, supporting structure is simply firm.
Further, described upper towbar lower end is provided with the upper pin hole that is connected with described sample.
Adopt the beneficial effect of above-mentioned further scheme to be, can seek voluntarily gravity vertical, guarantee that sample bears and the vertical force of central axis without skew.
Further, described sample holding device is provided with holding tank, and holding tank is provided with the downside pin axis hole.Shown in the lower end of sample be connected with described sample by lower bearing pin.
Adopt the beneficial effect of above-mentioned further scheme to be, adopt pin shaft structure mounting or dismounting sample convenient.Lower bare terminal end arranges holding tank, can firmly fix sample, and its left and right can not swung.
