Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan structure figure of Fig. 1.
Be labeled as among the figure: lower support 1, upper support body 2, depression bar 3, pressure head 4, sample support bar 5, sample backstay 6, guide-localization bar 7, back-moving spring 8.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1 and shown in Figure 2, bend-proof clamp of the present utility model, comprise support, depression bar 3, pressure head 4 and at least two sample support bars 5, described support has lower support 1 and upper support body 2, depression bar 3 slip caps are contained in the upper support body 2, pressure head 4 is connected depression bar 3 bottoms and is positioned at upper support body 2 belows, and sample support bar 5 is arranged on the upper surface of lower support 1.During work, bend-proof clamp of the present utility model is placed on pressure test machine platform centre, the Inorganic Non-metallic Materials sample (as cement sample or amorphous refractory sample) of 40mm * 40mm * 160mm is placed on the sample support bar 5, and makes position, sample center aim at pressure head 4.The starting pressure testing machine begins to exert pressure, and pressure head 4 moves down and break sample, measures maximum pressure value, stops to exert pressure, and rises pressure testing machine top, and pressure head 4 is resetted, and clears up the testing experiment of the next sample of beginning behind the residual sample.By the setting of this bend-proof clamp, only need to place it in to work on the pressure testing machine and get final product, do not need to adopt special bending test machine, thereby can reduce the cost in the sample testing process greatly, and can reduce floor area; And it is simple in structure, is convenient to make, and is easy to operate.
For reaching better detection effect, described sample support bar 5 has two, is set with sample backstay 6 between two sample support bars 5 at lower support 1 upper surface, and the height of described sample backstay 6 is greater than the height of sample support bar 5.Then when placing the Inorganic Non-metallic Materials sample, place it in earlier on the sample support bar 5, allow its side then, can guarantee the accurate placement of sample position, thereby guarantee test data accurately and reliably near sample backstay 6.
On the basis of above-mentioned embodiment, in order to reach better detection effect, be set with at least two pressure head guide-localization bars 7 at upper support body 2 lower surfaces, described pressure head guide-localization bar 7 slides and is set in the pressure head 4, the supporting plane that pressure head guide-localization bar 7 forms perpendicular to sample support bar 5.When then pressure head 4 down moves, can move, prevent that pressure head 4 from walking askew with the guiding of guide-localization bar 7; And pressure head guide-localization bar 7 is vertical with the supporting plane that sample support bar 5 forms, and can guarantee that pressure head 4 vertically presses on the Inorganic Non-metallic Materials sample that needs to detect.The supporting plane that sample support bar 5 forms is the placement plane of Inorganic Non-metallic Materials sample.
In the above embodiment, the lifting position on pressure testing machine top can be directly connected on the depression bar 3, then the lifting at pressure testing machine lifting position can drive the lifting of pressure head 4, and as optimal way, is connected with at least two group back-moving springs 8 between upper support body 2 and pressure head 4.By this version, the lifting position of pressure testing machine can directly be connected with depression bar 3.During work, pressure testing machine lifting position applies acting force on depression bar 3 when moving down, thereby drive ram 4 moves down, break sample after, pressure testing machine lifting position rollback, at this moment, under the effect of back-moving spring 8, pressure head 4 is returned to initial position.
For improving the transmission effect of pressure, depression bar 3 bottoms are connected with pressure head 4 by spherical pair.Thereby can guarantee the stable of pressure and accurately transmit.
