Description
Technical field
The present invention relates to tubing manufacturing technology field, especially relate to a kind of tubing band sample stretching device.
Background technology
In production, the test of the tensile property of tubing, typically tubing is cut a bit of clamping on stretching testing machine
To complete, rather than homogeneous tube measurement, so, the band sample intercepting from tubing is circular arc, and clamping method the most traditional is
By direct for band sample clamping, band sample can be made to deform, affect test accuracy.Traditional clamping method is in bar shaped test specimen
Two holes are made a call at two respectively, then screw or pin etc. are penetrated circular hole, and then fixing screws or pin are on tensile testing machine
Tested, but the shortcoming of this method is：Band sample always occurs bending and deformation and affects test result, and due to
The wall thickness of through hole to termination is too thin, and during experiment, through hole is easily destroyed, and leads to test to stop.
Content of the invention
The technical problem to be solved in the present invention is：In order to overcome common fixture in prior art can change the shape of batten
Thus affecting the problem of measurement result, provide a kind of tubing band sample stretching device.
The technical solution adopted for the present invention to solve the technical problems is：A kind of tubing band sample stretching device, including
Main frame, upper fixture, lower clamp and moving beam, described upper fixture includes the first fixed plate and the first clamping plate, and described first is solid
Fixed board is fixedly mounted on above main frame, and described first clamping plate center has a first through hole passed through for band sample, and described
The upper surface of one clamping plate have with band sample nose shape coincide the first groove, the center of described first groove with described
The center of first through hole is identical, and described lower clamp includes the second fixed plate and the second clamping plate, and described second clamping plate center is opened
There is the second through hole passing through for band sample, described second through hole is relative with the position of first through hole, described second clamping plate
Lower surface has the second groove coincideing with band sample nose shape, the center of described second groove and described second through hole
Center is identical, and described second groove is relative with the position of the first groove, and described second fixed plate lower surface is fixedly connected with screw thread
Bar, described threaded rod is in transmission connection at the center of moving beam, and described threaded rod is provided with nut, and described nut is located at mobile horizontal
The lower section of beam.
Band sample is inserted respectively first through hole and the second through hole, then rotate band sample, snap in band sample
After first groove and the second groove, host work.
The invention has the beneficial effects as follows, present configuration is simple, easy to operate, effectively solves plain clamp and leads to bar
The drawbacks of shape sample deformation image measurement result, reduce labour cost, improve work efficiency.
