Description
Technical field
The utility model relates to tubing manufacturing technology field, especially relates to a kind of tubing band sample stretching device.
Background technology
In production, the test of the tensile property of tubing, normally tubing is cut a bit of clamping to complete on stretching testing machine, instead of homogeneous tube is measured, like this, the band sample intercepted from tubing is circular arc, and the most traditional clamping method is by direct for band sample clamping, band sample can be made to be out of shape, to affect test accuracy.Traditional clamping method makes a call to two holes respectively at two of bar shaped test specimen, then screw or pin etc. are penetrated circular hole, then gib screw or pin are tested on tension tester, the shortcoming of this method is: band sample always occurs bending and deformation and affects test result, and because through hole is too thin to the wall thickness of termination, in the process of experiment, through hole easily destroys, and causes test to stop.
Utility model content
The technical problems to be solved in the utility model is: can change the shape of batten to overcome fixture common in prior art thus affect the problem of measurement result, providing a kind of tubing band sample stretching device.
The utility model solves the technical scheme that its technical matters adopts: a kind of tubing band sample stretching device, comprise main frame, upper fixture, lower clamp and moving beam, described upper fixture comprises the first fixed head and the first clamping plate, described first fixed head is fixedly mounted on above main frame, described first clamping plate center has the first through hole passed through for band sample, the upper surface of described first clamping plate has the first groove coincide with band sample nose shape, the center of described first groove is identical with the center of described first through hole, described lower clamp comprises the second fixed head and the second clamping plate, described second clamping plate center has the second through hole passed through for band sample, described second through hole is relative with the position of the first through hole, the upper surface of described second clamping plate has the second groove coincide with band sample nose shape, the center of described second groove is identical with the center of described second through hole, described second groove is relative with the position of the first groove, described second fixed head lower surface is fixedly connected with threaded rod, described threaded rod is in transmission connection at the center of moving beam, described threaded rod is provided with nut, described nut is positioned at the below of moving beam.
Band sample is inserted respectively the first through hole and the second through hole, then rotate band sample, after snapping in the first groove and the second groove to band sample, host work.
The beneficial effects of the utility model are, the utility model structure is simple, easy to operate, effectively solves plain clamp and causes band sample to be out of shape the drawback of vivid measurement result, reduce labour cost, increase work efficiency.
