In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a steel sheet Z-direction performance test device, includes anchor clamps and lower anchor clamps, it comprises clamping part and buckle part with lower anchor clamps to go up anchor clamps, clamping part includes steel column and stress column, the buckle part includes cylinder type foundry goods and draw-in groove, steel column one end links to each other with the stress column, stress column one end links to each other with cylinder type foundry goods, the draw-in groove that is used for connecting the dumbbell type sample is inwards offered to cylinder type foundry goods edgewise.

Preferably, the surface of the steel column is uniformly provided with grooves.

Preferably, the stress column is conical in shape, and the diameter section of the stress column increases from one end of the steel column to one end of the cone casting.

Preferably, the two ends of the dumbbell-shaped sample are respectively clamped into the clamping grooves corresponding to the upper clamp and the lower clamp.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model has the advantages of being scientific and reasonable in structure, convenience safe in utilization is fixed dumbbell type sample both ends through the draw-in groove to link to each other through steel column and experimental apparatus's anchor clamps and experiment, the welding that need not traditional mode prolongs sample both ends and carries out tensile test, makes the sample avoid receiving the damage in secondary processing, and the installation dismantlement is convenient, simplifies the operating procedure, facilitates the use, makes experimental testing result more accurate reliable.
